Gary Guthart
Thank you for joining us today. Our team performed well in the third quarter in the face of pandemic-related headwinds. The rise of the Delta variant and stresses in some hospitals pressured the demand for surgery. Global supply chain disruption has yet to abate, necessitating redirection of internal resources to continue to meet our customers demand.
Despite these challenges, growth in the use of our products continued in the quarter and capital demand remained robust. Our new platforms advanced in their commercialization, in their innovation, and in their clinical programs. Turning first to procedures, the increased COVID burden tempered the recovery we saw in the second quarter, particularly in the month of August.
The impact of the Delta variant drove procedures in the United States below our expectations at the start of the quarter with run rate stabilizing the last couple of weeks of September. Adoption continues in the United States, driven particularly by benign general surgery procedures including bariatric surgery, cholecystectomy, and hernia repair.
A trend in malignant procedures remains solid, including prostatectomy, hysterectomy, lobectomy, and colon resection. Two trends that have emerged over the past few years are the increased use of da Vinci in benign procedures, and rising use of our advanced instrumentation and targeted procedures.
Both are the result of focusing on our customers’ needs and delivering product and economic solutions to match. Outside the United States, procedure performance varied as a function of regional pandemic impact. In China, growths in the quarter were strong and span multiple specialties reflecting continued adoption.
In Japan and Korea, our procedure business remains healthy, with slight sequential procedure growth Q2 to Q3, despite COVID -related surgery disruption. Germany, the UK and France had reasonable year-over-year procedure growth and our customers are having success in diversifying procedure categories beyond urology.
Regarding the capital environment, new system placements continued to be robust. The United States had an outstanding capital quarter with a balanced mix of hospitals new to da Vinci, as well as healthy incremental placements for existing customers, and trade-ins of older technology.
This performance has been driven by collaboration with U.S. integrated delivery networks, as they thoughtfully manage and expand the capacity of their da Vinci fleets. Elsewhere, China, Japan, and Europe had solid placements in the quarter, and our placements in Brazil showed strength.
Turning to our newer platforms. Our single-port system da Vinci SP had a solid quarter as we pursue additional indications. Placements of our flexible bronchoscopy platform Ion grew nicely sequentially in Q2 to Q3, powered by continued strong customer experiences in the field. Our finances were strong again this quarter though they followed an unusual path.
System strength and favorable system sales mix drove strong system revenue. Procedures grew at the low end of our expectations as a result of the Delta variant. Instrument and accessory revenue per procedure moved down modestly as benign procedures continued to make up more of the procedure mix and our extended-use instrument program reaches equilibrium in the field.
Our spending grew sequentially and year-over-year as we continue to invest in expanding our new platforms and digital programs, as well as builds our go-to-market capabilities globally. Our expense growth was again modestly lower than planned, driven by some increase in time to fill open positions in a tight labor market, lower travel-related spending given the pandemic, and some under-spending in prototypes.
We will continue to invest in programs that fulfill the mission and build the Company. Turning to our innovation efforts, we developed and deployed technology-enabled solutions to support our customer’s pursuit with the [Indiscernible]: better outcomes, better patient experiences, better care team experiences, and lower total cost to treat per patient episode. I would like to take a moment to overview the clinical status of our programs.
For our da Vinci system, there are now over 9.7 million lifetime procedures performed with over 28,000 peer-reviewed clinical publications. Da Vinci X and XI now have over 70 representative clinical usages allowing broad use across multiple clinical specialties from urology to gynecology, thoracic surgery, general surgery, and trends oral surgery. Tens of thousands of surgeons routinely use our multi-port systems.
We continue to invest in our multi-port products, instruments, and services to further expand our capabilities and indications. Many surgeons continue to work with us to pursue new learning with several prospective studies ongoing. Our flexible bronchoscopy system, Ion, continues to build momentum clinically and commercially, with several presentations and manuscripts updating Ion clinical progress at the 2021 CHEST conference this weekend.
As described in yesterday's press release, early clinical trial results point to outstanding capability allowing for definitive diagnosis of harder to reach body regions. Our teams are hard at work building our manufacturing and supply capabilities to meet rising demand. Our single-port system SP has a clinical database of 28 peer-reviewed clinical publications.
There are currently several ongoing prospective studies for SP in Korea and the United States, including our IDE trial for colorectal indications. This quarter, we received FDA approval of our unit portal thoracic IDE. Broad SP adoption will be paced by additional regional and clinical clearances, which remain our focus for the SP program.
Our digital solutions provide data-driven insights to surgeons, operative services and hospital administration. For virtual reality training to efficiency insights, to custom comparative outcomes analysis, these tools are now routinely employed by our customers and our teams to improve programs. Our analytics program supported thousands of customers in the quarter.
Turning to machine learning, our teams are at the leading edge of [Indiscernible] -based clinical science for surgery through our collaborations with leading academic centers, informing algorithmic and scientific discovery. Taken together, these programs allow our customers to quantify our collective impact on the quadrupling quarter [Indiscernible].
Before turning the time over to Marshall, today we announced some changes in responsibilities of our senior executive team. These changes are the result of a structured process over the past few years, and they are driven by our need to support growth in our product lines, commercial reach, operations capabilities and business infrastructure, as we scale to meet the global opportunity to advance minimum invasive care.
Starting January 1st, 2022, our Executive Vice President and Chief Business Officer, Dave Rosa, will take on an important new role of Executive Vice President and Chief Strategy and Growth Officer, leading our efforts to identify and realize long-term business opportunities, continuing to build the value of our integrated product offerings, and ensuring our customers clearly understand the value of our ecosystem in creating successful, minimally-invasive programs.
Henry Charlton, currently General Manager of the U.S. and Europe, will succeed Dave as Chief Commercial Officer overseeing global commercial sales, regional marketing, and commercial enablement. Also, Marshall Mohr will take on an important new position as Executive Vice President Global Business Services, bidding Intuitive 's continued growth in information technology, and our enterprise process, data and systems, and global facilities.
Jamie Samath, we will succeed Marshall as Chief Financial Officer. They are each outstanding proven leader and will report to me. We expect them to spearhead our efforts to achieve our mission and continue to position Intuitive as first choice of our customers in a growing marketplace. I'll now turn the call over to Marshall, who will take you through our financial highlights in greater detail.
Marshall Mohr
Good afternoon. I want to describe the highlights of our performance on a non-GAAP or pro forma basis. I will also summarize our GAAP performance, later in my prepared remarks. Reconciliation between our pro forma and GAAP result is posted on our website.
The information in our earnings release and within our prepared remarks reflects the 3-for-1 stock split completed earlier in October. Overall, third quarter procedures grew 20% year-over-year and reflect the impact of Delta variant resurgence. COVID also impacted third quarter 2020 procedures, making year-over-year comparisons complicated.
In the U.S., procedures grew 16%, reflecting the impact that COVID resurgence had on hospital resources regionally, the impact of the resurgence was most pronounced in August and early September, and regionally in the south and southeast. Later in the quarter, as COVID cases began to slow, procedures began to recover.
However, it is difficult to estimate the extent to which this resurgence or future resurgences will impact da Vinci procedures. Year-over-year, OUS procedures grew 30% with the impact of COVID varying regionally. In Europe, COVID had a greater impact in Italy and France, and less in UK and Germany.
While there continued to be COVID hotspots within some of our Asia-Pacific markets, overall procedures in the region performed well. China growth in the third quarter continued to be far higher than other regions, primarily reflecting system installation growth over the past year. Relative to the beginning of the pandemic, many hospitals are able to better manage increased COVID patient hospitalization.
However, staffing shortages and hospital supply chain issues are challenging some hospital capacities and could impact deferrable procedures, including da Vinci procedures, going forward. Jamie will provide additional procedure commentary later in this call. Key business metrics for the third quarter were as follows.
Third quarter 2021 procedures increased approximately 20% compared with third quarter 2020 and decreased approximately 3% compared to the last quarter. Compound annual growth between the second quarters of 2019 and 2021 was 13.5%. Third quarter system placements of 336 systems increased 72% compared with 195 systems for the third quarter of 2020, and increased 2% compared with 328 systems last quarter.
We expanded our installed base of da Vinci systems over the last year by 11% to approximately 6,525 systems. This growth rate compares with 8% last year and 10% last quarter. Utilization of clinical systems in the field measured by procedures per system, increased approximately 9% compared with last year, and decreased 6% compared with last quarter.
Compounded annual utilization growth rate between the third quarters of 2019 and 2021 was 3%. Moving on to capital placements, system placements in the quarter reflected a continued trend of IDN multi-system purchases and were driven by procedure growth and hospitals upgrading in order to access our standardized and fourth-generation capabilities.
Looking forward, we see the following capital revenue dynamics. Procedure growth drives capital purchases in many of our markets, to the extent that COVID impacts procedures, it will also impact capital purchases. The trading cycle has been a tailwind to system placements. However, as the installed base of older generation product declines, the number of trade-ins will decline over time.
Leasing and alternative financing arrangements enabled customer access to our systems. While the percentage of systems placed under operating leases fluctuate quarter-to-quarter, we believe leasing will increase as a percentage of sales over time, which will result in the deferral of otherwise current revenue into future periods.
Macroeconomic conditions created by COVID could regionally impact hospital capital spending, and as competition progresses in various markets, we will likely experience longer selling cycles and price pressure. Additional revenue statistics and trends are as follows. Third quarter revenue was 1.4 billion, representing a 30% increase from last year and a 4% decrease from last quarter.
The compound annual revenue growth rate between the third quarters of 2019 and 2021 was 12%. The year-over-year revenue increase reflected growth in both procedures and system placements. The decrease relative to the second quarter of 2021 reflects lower instrument and accessory revenue associated with lower procedures and increased leasing as a percentage of placements.
Leasing represent 41% of current quarter placements compared with 35% last year and 33% last quarter. Leasing as a percentage of total sales has and will continue to fluctuate with customer and geographic mix. However, we anticipate more customers will seek leasing or alternative financing arrangements than reflected in historical run rates.
40% of systems placed in the third quarter involve trade-ins, which is consistent with the 40% last year and higher than the 38% last quarter. As customers continue to upgrade to fourth-generation capabilities, the population of installed SI is decreasing, particularly in U.S. where 97 trade-ins were completed in the third quarter, leaving an installed base of SIs of approximately 425 systems.
As a result, we expect lower trade-out transactions over time. Trading activity can fluctuate and be difficult to predict. Third quarter average selling prices increased to 1.57 million from 1.55 million for both the third quarter of 2020 and the second quarter of 2021. Average selling prices will fluctuate with geographic and product mix.
Consistent with historical patterns, we expect a higher mix and systems sold to distributors in the fourth quarter, which carry lower prices. We recognized 25 million of lease buyout revenue in the third quarter compared to 17 million last year and 26 million last quarter. Lease buyout revenue has varied significantly quarter-to-quarter, and will likely continue to do so.
Instrument accessory revenue per procedure of $1,900 decreased slightly compared with $1,910 per procedure for the third quarter of last year, and decreased compared with $1,940 per procedure in the second quarter. The year-over-year change reflects increased usage of extended-use instruments, mostly offset by increased usage of our advanced instruments.
The decrease from the previous quarter reflects customers continuing to adjust their instrument buying patterns to reflect the additional uses per instrument included in extended-use instruments. Ten of the systems placed in the third quarter were SP Systems. Our installed base of SP Systems is now 89, 10 in Korea, and 79 in the U.S.
We continue our measured roll out of SP as we work on gathering clinical data to gain additional procedure clearances in the U.S. We placed 28 Ion systems in the quarter, bringing the installed base to 98 systems. There were approximately 2,000 Ion procedures completed in the third quarter. Ion system placements and procedures are excluded from our overall da Vinci system and procedure counts.
Our rollout of [Indiscernible] Progressing well. Outside the U.S. we placed 109 systems in the third quarter compared with 79 in the third quarter of 2020 and 115 systems last quarter. Current quarter system placements included 47 into Europe, 20 into Japan, and 17 into China, compared with 39 into Europe, 15 into Japan, and 12 into China in the third quarter of 2020.
We also placed 9 systems in Brazil in the third quarter and now have placed 23 systems in Brazil over the past four quarters. Moving on to gross margin, and operating expenses. Pro forma gross margin for the third quarter of 2021 was 71.3% compared with 70.2% for the third quarter of 2020 and 71.7% last quarter.
The third quarter of 2020 included 23 million of service credits issued in conjunction with our customer relief program, higher period costs associated with lower production levels, and higher excess and obsolete inventory charges. The decline in gross margin relative to the second quarter primarily reflects product mix.
Product and customer mix fluctuate quarter-to-quarter, which can cause fluctuations in gross margins. COVID has impacted global supplier of semiconductors and other materials used in our products. While to date we've been able to secure supply necessary to ensure fulfillment of customer demand, our teams are expending significant time and effort to bridge future supply with demand.
To date we've experienced immaterial component increase, cost increases, and freight expedition fees. However, global shortages could result in future supply disruptions as well as delayed development and regulatory activities. We also expect supply issues to result in higher production costs.
Pro forma operating expenses increased 21% compared with the third quarter of 2020, and increased 2% compared with last quarter. The increase, compared to the prior year, reflects costs associated with higher headcount, increased variable compensation, and increased spending in areas impacted by COVID.
Third quarter spending was below our expectations due to delays in headcount hiring and lower spending on activities restricted by COVID, including clinical development, marketing events, and travel costs. In addition, COVID delayed some R&D work resulting in under spend on prototypes. We expect spending on activities restricted by COVID to increase as the impacts of the pandemic decline.
We also expect spending to increase as a percentage of revenue as investments in headcount infrastructure and other support area s catch-up to the growth of the business. Finally, we expect to continue to invest in expanding and accelerating our ecosystem of products and capabilities. Jamie will provide spend guidance later in this call. Our pro forma effective tax rate for the third quarter was approximately 24%.
We recorded expense of 11 million associated with periods prior to 2020 related to guidance recently provided by the IRS associated with stock-based compensation. We expect our pro forma tax rate for the fourth quarter to be approximately 21.5%. Our actual tax rate will fluctuate with changes in geographic mix of income, changes in taxation made by local authorities, and with the impact of one-time items.
Our third quarter pro forma net income was 435 million, or $1.19 per share, compared with 334 million, or $0.92 per share, for the third quarter of 2020, and 477 million or $1.31 per share for the last quarter. Third quarter 2021 and 2020 included pre -tax gains of approximately 8 million and 62 million associated with investments in companies that resulted from development agreements entered into in prior years.
I will now summarize our GAAP results. GAAP net income was 381 million or $1.04 per share for the third quarter of 2021 compared with GAAP net income of 314 million or $0.87 per share for the third quarter of 2020 and GAAP net income of 517 million or $1.42 per share for the last quarter.
We ended the quarter with cash and investments of 8.2 billion compared with 7.7 billion last quarter. The increase in cash in the third quarter primarily reflected cash from operations and stock exercises. We did not repurchase any shares in the quarter. And with that, I'd like to turn it over to Jamie.
Jamie Samath
Thank you, Marshall. Our overall third quarter procedure growth was approximately 20% compared to growth of 7% during the third quarter of 2020. Q3 procedure growth reflected 16% growth in U.S. procedures, and 30% growth in all U.S. markets. In the U.S. procedures in Q3 were adversely impacted by an increase in COVID related hospitalizations due to the Delta variant.
Procedures were particularly impacted in those states with relatively lower vaccination rates. As the number of COVID-related hospitalizations peaked and began to improve in September, we saw U.S. procedures start to recover. Q3 growth reflected relative strength in bariatric procedures, cholecystectomy, and hernia repair.
In the more mature procedure categories, year-over-year growth in prostatectomy was strong relative to historical averages and benign hysterectomy grew in the low single-digits range. Third quarter OUS procedure volume grew approximately 30% compared with 9% growth for the third quarter of 2020.
Third quarter of 2021 OUS procedures were driven by growth in prostatectomy and earlier stage growth in general surgery, gynecology, kidney cancer procedures, and thoracic surgery. China procedure growth remain strong and broad-based as a result of continued expansion of the installed base under the current quarter and the addition and training of surgeons new to the da Vinci platform.
Growth in Japan was solid, but was impacted by localized lockdowns stemming from ongoing efforts to prevent resurgences of COVID. Growth in Korea was also solid, primarily driven by gynecology, urology, and head and neck procedures. A little more than half of the procedures in these three key Asian markets are outside of urology.
In Europe, procedure growths vary by country based on the relative impact of the Delta variant and the impact of COVID -related mitigation measures. Growth in the UK and Germany was solid, with procedure growth in France and Italy impacted by reduced capacity for surgery as hospitals reserved resources for potential increases in COVID patients.
During Q3, customers in the U.S. and Europe effectively consumed their remaining inventory of 10 life instruments following the launch of extended-use instruments in those regions in Q4 of last year. With this full adoption in the U.S., customers are benefiting from INA per procedure costs that reduce by approximately 10% in lower acuity procedures such as cholecystectomy and hernia repair.
In Europe, customers are benefiting from an even larger reduction in NIA costs for target procedures. While recent procedure trends are confounded by the various waves of the pandemic, we believe based on customer feedback that the adoption of extended-use instruments is having a positive impact on targeted procedures.
In our new platform, Ion procedures increased almost 4 folds as compared to Q3 of 2020, driven by significant expansion of the number of systems of customers and an increase in usage in the existing installed base. Our single-port platform, which is gauged by additional regional and clinical clearances, showed solid performance with almost 50% year-over-year procedure growth.
Now, turning to the clinical side of our business, each quarter on these calls, we highlight certain recently published studies that we deemed to be notable. However, to gain a more complete understanding of the body of evidence, we encourage all stakeholders to thoroughly review the extensive details of scientific studies that have been published over the years.
During the quarter, Dr. Michael Kent from Beth Israel Deaconess Center, Harvard Medical School in Boston, Massachusetts, published results from a landmark multi-center Pulmonary Open, Robotic and Thoracoscopic Lobectomy or PORTaL study in y the annals of surgery.
This retrospective study sponsored by Intuitive compared lobectomy outcomes associated with open, VATS, and robotic assisted da Vinci surgery with over 6,000 cases included in this analysis. After 1-to-1 propensity score matching, a comparison of open and da Vinci lobectomies with approximately 800 patients in each group, showed a two-day shorter length of stay, and a 9.5% lower rate of prolonged hospital stay associated with da Vinci lobectomies.
The da Vinci cohort also had an approximately 8-minute shortened [Indiscernible] time for cases without a concomitant procedure. Post - operative complications were approximately 9% lower with the da Vinci robotic approach.
With regards to the propensity score match comparison of minimally invasive approaches with over 1,700 patients in each group, the da Vinci approach evidenced of 1.1 day shorter mean length of stay, and a 6.1% low rate of conversion to thoracotomy when compared to VATS, with the differences in conversion rates report for each tumor stage in the analysis.
The authors concluded in part, "In this retrospective multi-institutional data analysis, both robotic-assisted and VATS lobectomy were associated with improved peri -operative outcomes compared to open lobectomy. " Robotic-assisted lobectomy was associated with additional differences compared to VATS, such as a reduced length of stay and conversion rate.
In August of this year, Professor Umberto Bracale from the University of Naples Federico II in Naples, Italy published a systematic review with meta-analysis of transversus abdominis release (TAR) for ventral hernia repair, assessing short-term outcomes of the open and robotic-assisted approaches.
The macroanalysis combined six studies, containing over 800 patients, of whom just over 200 patients underwent robotic - assisted da Vinci surgery, and just under 600 patients who underwent the open approach. Results of this macroanalysis found that robotic-assisted approach was associated with a full point 4 day shorter length of stay, 64% lower risk of post-operative complications, and 79% low risk of developing systemic complications.
Readmission and reoperations were comparable between both groups. The office concluded in part, "Based on the data for the metro analysis, the robotic approach for TAR seem safe and feasible, even in more difficult cases. Robotic assisted TAR shows the common advantages of minimally invasive procedures that improve short-term outcomes with significant benefits in the early post-operative period. "
Lastly, as noted in yesterday's press release, preliminary results from the precise study evaluating outcomes associated with the Ion endoluminal system will present into the Annual CHEST Conference. This preliminary analysis of 69 subjects showed a diagnostic yield of 83% with a sensitivity of malignancy of 84% to 88% from the biopsy of peripheral pulmonary nodules with a mean size of 17 millimeters.
These initial outcomes regarding the performance of the Ion system are encouraging and we look forward to the full study being published in the second half of 2022. I will now turn to our financial outlook for 2021. During Q3, we experienced a more challenging supply chain environment for the deterioration in on-time delivery performance from our suppliers. We also saw increased supply chain costs.
While this did not have a material impact to our operating results in Q3, the outlook we are providing does not reflect any potential significant disruption or additional costs related to supply constraints. Starting with procedures, last quarter we forecast 2021 procedure growth of 27% to 30%. Given Q3 results and the impact of the Delta variant, we are now narrowing our full cost and expect full-year 2021 procedure growth of 27% to 29%.
This procedure outlook does not reflect a significant impact from a [Indiscernible] stopping shortages or a resurgence of COVID-19. The high-end of the range assumes the COVID-19 related hospitalizations in the U.S. continued the recovery that began in September, and the COVID -related mitigation measures in OUS markets continued to ease.
Turning to gross profit, on our last call, we forecast our 2021 full year pro forma gross profit margin to be within 70.5% and 71.5% of revenue. We now expect 2021 pro forma gross profit margin to be within 71% and 71.5% of revenue. This range does not reflect any significant disruption associated with the current supply chain challenges.
Our actual gross profit margin will vary quarter-to-quarter, depending largely on product, regional, and trade-in mix, the impact of product cost reductions in manufacturing efficiencies, and competitive pricing pressure. With respect to operating expenses, on our last call, we forecast to grow full-year pro forma 2021 operating expenses between 17% and 21% above 2020 levels.
We are refining our estimate and now expect a full-year pro forma operating expense growth to be between 17% and 19%. We expect our non-cash stock compensation expense to range between 450 and 460 million in 2021. With regard to pro forma other income which is comprised mostly of interest income, we expect a range of between 50, 55 million in 2021.
Finally, with respect to income tax, we expect our Q4 2021 pro forma tax rate to be approximately 21.5% of pre - tax income. That concludes our prepared remarks. We will now open the call to your questions.
Question-and-Answer Session
Operator
Ladies and gentlemen, if you'd like to ask a question [Operator Instructions]. We'll go first to Amit Hassan with Goldman Sachs. Your line is open. Please go ahead.
Amit Hazan
Hello. Thanks and good afternoon. I want to come back to the supply chain comment first. Just ask you how visibility looks for componentry now versus maybe a little bit earlier this year, what lead times look like now, it sounds tighter, just a little more color around that and to what extent have you already been able to either double order, for lack of a better term, I guess, or stockpile this year, and how viable of an option does that remain for you?
Marshall Mohr
Yes. I think -- Amit, it's Marshall. The environment, as it relates to supply chain, has deteriorated and got more difficult over time. And as we said, we've dedicated substantial resources to dealing with those shortages. And it has not, to-date, created an issue with us supplying customer demand. But there is a risk, and it's a real risk until we call it out to make sure that everybody is aware of that.
From the perspective of costs, we talked some cost increased material costs last quarter. They were not significant. And we also incurred some expediting fees associated with freight. Again, not material. But going forward, we do expect increased costs, and that will probably hit the margin in Q4 or Q1. It's hard to predict exactly how much until -- I think that summarizes it for you. It's difficult environment right now.
Jamie Samath
I just -- I think our supply chain and manufacturing teams are doing great. I think they're working in a tough macro-environment, and that macro-environment will clear up when it clears up.
Operator
Our next question we go to Larry Biegelstein with Wells Fargo. Go ahead, please.
Lawrence Biegelsen
Good afternoon. Thanks for taking the questions. Just two for me: one on Ion, Gary, and then one on procedures. So the precise data look good. Yesterday, I guess the question is do you think the early data suggests your shape sensing technology can lead to better yields and lower pneumothorax rates versus your main competitor, which uses a different technology? And how much of a catalyst do you think the data from yesterday will be for Ion? And I just have one follow-up.
Gary Guthart
Yeah. I think that the architecture as a whole, the shape sensor, the way it works, the design choices about making a soft catheter that's quite and can go deep into the [Indiscernible] been really strong for us. And I think the data speaks for itself.
You can compare for yourself the data that focuses and that for Monarch, and we feel great about where we are. I think it is catalyzing. As we speak, I think that those results are helping us in the market. Our customers are giving us really good feedback. And we continue to invest in operations part of that program as well as the innovation side. We feel really good about.
Lawrence Biegelsen
Thanks for that, Gary. And then on procedures, I guess it sounds like most or if not all major markets are moving in the right direction. I'd love to hear a little bit more color, particularly on the U.S. and it sounds like Jamie, and by the way congratulations on the new role, it sounds like we should expect normal seasonality in Q4.
When we look at 2018 and 2019, the sequential procedure growth was very similar worldwide U.S. and OUS, is it possible that it could be a little stronger given that we're seeing a recovery? Thanks for taking the question.
Jamie Samath
Thank you, Larry, by the way. I would say this, what are reflected in the high-end of our procedure guidance are really two things. Those COVID-19 related hospitalizations in the U.S. continued the recovery that began in September, and that was in the middle part of September that that recovery commenced. So there's a progression there that continues through Q4.
It also assumes that the mitigation measures in OUS markets, which are typically a little more conservative than we see in the U.S., continued to ease, and those also started to ease in September. At the low end, what we see is a slower recovery in the U.S. from what we saw in Q3 and choppiness OUS in terms of the on-off of mitigation measures in various markets. And so that range of 27% to 29% that we provided, really it's just a function of the rate at which we recover from what occurred in Q3 with the Delta variant. That was a little color on that.
Lawrence Biegelsen
Thanks so much. Yeah. Go ahead.
Gary Guthart
Just jumping in. I think there are two things that are going on. One is, what will pace us is hospital availability for surgery [Indiscernible] it. It's not infection rate, it's going to be resourced consumption at the hospital and their ability to pivot their resources, both human capital and facilities, back towards surgery.
As you double-click on that, some of it is regional variance, but some of it is actually just hospital system variance. There are differences in how each hospital has managed it. So it's hard to generalize, I think, beware of averages.
Lawrence Biegelsen
Got it. Thanks for taking the questions.
Operator
Next question comes from Bob Hopkins with Bank of America. Go ahead, please.
Robert Hopkins
Thank you and good afternoon. Just to follow up on that last question. So for Jamie or Marshall, I guess, therefore, do the procedure volumes that you are forecasting for Q4, is that assuming improving year-over-year growth in Q4 versus the year-over-year growth in Q3, or about the same?
Jamie Samath
Yes. The -- I think what's implied by the guidance that we provided at the low-end of Q4 year-over-year growth will be 15%. At the high end, it will be 22%. So you compare that to what we showed in Q3 of '20, and you see the range is above and below what we recorded in Q3. And I think again, it just reflects both the year-over-year comparison in terms of the base for Q4 in 2020 as well as the range of scenarios in terms of what actually occurs with procedures in Q4.
Robert Hopkins
Okay. Thank you for that. And then just one quick one for Gary, I was struck by your comments in your opening remarks about your -- how your multi-port systems now have 70 clinical uses. And I was curious, you just elaborate on that a little bit. Is that 70 different surgical procedures or how are you characterizing clinical usage? I found that an interesting number.
Gary Guthart
Yeah, that's right. It's the number of different procedures that's described in our labeling as to where this might be used in the body or in sub-specialties. So if you look in urology, there's a handful of different procedures that it can be used for and likewise gynecology general surgery. And as you just walk through, that's a set of procedures for which we've engaged the agency and put in our labeling. So they are quite broadly applied.
Robert Hopkins
Okay. My model only has 10, so I guess I have some work to do. Thank you.
Gary Guthart
You got 10. And we're not done. I think surgeons and we and regulatory agencies around the world continue to explore where else technologies like ours can go.
Robert Hopkins
Thank you.

Next question comes from Tycho Peterson with JPMorgan. Please go ahead.
Tycho Peterson
Good afternoon. I wanted -- I think you can elaborate a little bit more on the staffing shortage comments. I know this isn't maybe fully baked into guidance, but how much risk do you think this presents? How widespread it did? Obviously, there's very tight labor market, but just something you're seeing across most of your customers or how would you characterize it?
Gary Guthart
On the -- you're referring to the customer side?
Tycho Peterson
Correct.
Gary Guthart
Yeah. Jamie wanted to talk a little bit about it.
Jamie Samath
Yeah. We've had anecdotal inputs from some customers that they're facing staffing shortages. Other customers have said to us that they're able to overcome those risks. And so given the mix dynamics and the lack of clear evidence in terms of its impact on procedures, what we've said is the remainder of the year guidance does not reflect any significant disruption from the last staffing shortages, meaning that there's no deterioration in the phenomena for hospitals.
Tycho Peterson
And then another dynamic you flagged was just the selling cycle. Obviously, early days on the competitive front, but on the back of the CE Mark for Medtronic, I'm just curious, out of your -- what you're hearing from your sales reps just in terms of early interest, potential demos things like that.
Gary Guthart
Yeah. I think with several of the other systems that are on the market, and as you say, the most recent one, we see early engagement. Those first engagements tend to be a placement of clinical trial sites and training centers and so on. So they are not surprising. They're their early access programs to get into the market up.
So far there are far a number of claims about what these new systems will do and I think the reality is time will tell the genuine systems. I think evidenced has to be generated to backup those claims. And so far, we don't see anything yet that looks like evidence. Just the said claims, so we'll keep serving our customer, doing what we can to make sure that they can achieve the quadrupling. And we'll see how other companies do.
Tycho Peterson
Maybe last one, we have[Indiscernible] we always get the question about new system for you guys. It feels like that you picked up a little bit lately. You're putting up good system numbers. I'm curious in your view, is that something the market needs right now? What do you wanted to say, if anything at all, about the appetite for another system from you guys or anything you may be working on?
Gary Guthart
First thing is that we think there is room for innovation on all the platforms we have. So whether it's multi-port and Gen 4, we continue to innovate. We've done a lot of sequential innovation on Gen 4, so our X and XI are different [Indiscernible] we continue to invest both in incremental opportunities and in deeper, bigger opportunities on multi-port.
And as we're ready to roll those out, you'll hear about it. We brought to market SP, we continue to innovate on SP, and get sequential products and clearances globally for SP. And likewise Ion, which is having great success early in its first indication but we think has opportunities deeper in the body and different locations in the body, which will proceed and describe over time.
So yeah, I think you should expect continued innovation from us. As to whether we think that we're in immediate need of something, we are innovating at a pace where we think we can bring things that matter to the quadrupling, not so much an idea of what's our retail strategy, but more can we do something that changes quadrupling or otherwise improves the customer experience, and that's what we're focused on.
Tycho Peterson
Okay. Thank you.

Next question comes from Rick Wise with Stifel. Go ahead, please.
Frederick Wise
Good afternoon, everybody. One focused question and then a larger picture when Gary when you -- in your opening comments, you mentioned that extended life instruments, if I understood, have reached I thinks the urban forward was equilibrium.
I just want to make sure I understood what you were implying that suggest that the initial phase of adoption has happened and we're going to see better growth X, sort of initial stocking ASP impact. And is there a second round of instruments? This has been so successful. How all should we think about all that?
Gary Guthart
Well, with regard to what I meant by equilibrium, it was really that the initial stocking orders and the transition from older instruments to newer is largely taking place, but I'll let Jamie answer that more carefully than I just did.
Jamie Samath
Actually, I think that's right, Gary. There's a period of time when as we launched extended-use instruments, customers in the U.S. and Europe in particular were ordering those instruments array higher than their usage as they consume the 10 life instruments that took some time to gain to parity. And so you saw in the end of positive benefit to Ion per procedure in Q1 and Q2.
Q3 for those regions that largely came to parity. We did launch extended-use instruments later in Asia and some of the rest of the world countries. And so they are still working their way to parity. So there will be small downward pressure on NIA per procedure holding everything else equal as they get to parity looking forward.
Frederick Wise
Thank you.
Gary Guthart
The second half of your question, just to finish it, you talked about are we done, is that it for these kinds of ideas and extended-use instruments and da Vinci[Indiscernible], these were design and process investments that we made to pursue what we think of is the virtuous cycle. The idea that if we can improve quality and lower cost for our customers, that they can use our products in more and different procedures.
And we're not done doing that. It may not look exactly like what we've done in the past, there are other things that we think we can do with it. Allow them high-value systems at different price points, or value instruments at different price points, so that line of reasoning has not exhausted.
Frederick Wise
And Gary, just one last big picture question. Obviously, you've created 2 new senior leadership roles here, for Marshall and for Dave Rosa. Maybe just -- if you could just flush out your thinking.
Is it simply -- and it would be enough that Intuitive has gotten so large and complex in the future, to survive, you just need more senior leadership -- focused leadership? Or what are you charging? What are you expecting? What should we expect from Marshall and Dave in the coming years? Thank you.
Gary Guthart
Thank you for that question. Over the last few years, we've had an expansion of business and expansions of opportunity, both are happening. On the business side, we want to make sure that we serve our customers at very high-quality quickly in local regions where we can, and that we take advantage of a lot of the systems enterprise data that we have to help drive the business and help our customer.
And that's something that Marshall has been doing and I've asked them to double down on that to make sure that we can really take advantage of our global scale and serve our customers in our business really well at that scale. And it's an opportunity and it's a real work. The flip side is I have never been more positive about the long-term opportunity for companies like ours that can master the kinds of things that we have to do to help minimum invasive care and interventions.
And so there's real opportunity there. And I'd like us to get there quickly to have the agility and focus to be able to open new ideas and new architectures and new markets. And I can think of nobody more qualified to lead that effort than Dave Rosa, who is visited just about all parts of the Company.
He started off as an engineer and scientist and has done many things for us. So we're really trying to get the advantages of scale to help our global customer and also be agile in capitalizing on growth opportunities as we see them.
Frederick Wise
Thank you so much, Gary.

Next question comes from Matt Taylor with UBS. Go ahead, please.
Matt Taylor
Hey. Thanks for taking the question. I was hoping maybe, Marshall, you could talk a little bit more about the supply chain issues from the standpoint of just helping us get visibility or understand how close you are to the edge there. And meaning, you keep calling out this risk that exists but it sounds like you've been doing a really good job with managing things so far.
Is there any benchmark numbers you can give us to help us understand what the lead times are in some of the key things that could get disrupted or the likelihood that it will happen? Is it getting better or is there a real risk of you not being able to ship some product is I guess the core of the question?
Marshall Mohr
I don't think I can say it's getting better. I actually think that it's difficult situation and will continue for some time. If you think about the one that's been talked about the most, the semiconductors, you've seen it in the auto industry, it's an issue in computers. And if you had to order any home goods that contained chips, you would know that there's a problem there.
That will take a long time to remedy. It takes a long time to build fabs, it takes a long time to produce product, and so I think that will go well into next year the predictions that we're hearing. I think Gary told you our team has done a marvelous job so far. So I think there are issues on a regular basis, and the issues so far that our team has been able to resolve those.
I don't have any statistics to provide you on how often, or what it means. I would just say that some -- anecdotally, some lead times have extended beyond 6 months. That's not all our products, and it's not an average you should apply to everything, but in some cases it's pretty long. And so I think it's a problem we highlight as just to make sure that you're aware of the risk.
Matt Taylor
Okay. Thank you very much.
Operator
And we have a follow-up question from Amit Hazan with Goldman Sachs. Go ahead, please.
Amit Hazan
Thank you for that. I thought maybe just to follow up on the spiky question was just a little bit more on just inflationary headwinds generally. And Marshall, just how you're seeing labor costs growth today versus early in the year or more normal times and raw material cost growth versus normal times.
And it's just hard for us to start thinking about these things along with what you commented on the supply chain for next year is just qualitatively as we start to think about where operating margins might go.
Marshall Mohr
We've seen some cost increases. Again, they haven't been that significant. And frankly, our teams have done a marvelous job of sort with efficiency and effectiveness to offset those increased costs. But we're hearing from suppliers that they're going to raise their prices.
And so we're saying that hey, we expect that costs will go up more. Not sure. I want to say that the inflation where it is has hit us and am here to stay, but we are seeing some supplier's raise costs.
Amit Hazan
Thank you.

Our next question comes from [Indiscernible] Evercore ISI. Evercore ISI,? go ahead, please.
Vijay Kumar
Hey guys. Thanks for taking my question. Gary, maybe 2 quick one’s for you. The precise study 80% diagnostic resolution. Could you -- is that good enough, Gary? Certainly, when -- the headline numbers, when we look at other studies, it's a good number. But I'm just curious, is the point where the market beckon to these new numbers and should we see an inflection in adoption of Ion?
And just one quick one on 3Q. I know you called out the Delta but was there any labor shortage impact in 3Q itself? Because historically we haven't seen the pandemic impact or Intuitive has outperformed peers. It just perhaps a little excessive in 3Q. Was there something else going on? Thank you.
Gary Guthart
Okay. On the first one, in terms of diagnostic yield, you had said 82% and I guess what I'd advise everybody is, there's a couple of numbers that are important and they stay linked together. And that is what the size of the lesion is? And then what's the positive diagnostic rate, the ability to definitively diagnose? That's what the interventional pulmonologists are looking at.
So the bigger the lesion, if it's 3-centimeter lesion, your diagnostic yield rate is going to go up your definitive[Indiscernible] because it's easier to hit. So you got to look at both numbers. It's not a single metric. So 82 for smaller lesions are leading, as far as I can tell for endobronchial approaches for that approach. Some folks can get to higher yield rates, but they are hitting bigger targets.
So you need to look at both, and that's what I encourage you to do. The second thing that I advise you is that there are other ways to examine or get a biopsy. There can be outside the body, CT-guided needle biopsies, and those outside the body CT-guided needle biopsies have high success rates at gathering the tissue, but they have a lower safety profile than the endobronchial approach.
So there's a third dimension, which is, did you get the tissue you needed to get a definitive diagnosis? How big was the lesion you were trying to target? Then what was the complication rate. And we think that Ion is really good at managing all 3 of those relative to competitive approaches, and we're seeing a nice uptick as a result. And is that a tipping point? We'll see. So far, so good. That's what we had expected.
This kind of performance, that's what we were targeting. We're pleased to see it being borne out over multiple sites and multiple customers, and we think that's going to be helpful. With regard to your second question, you were talking a little bit about are we seeing an unusual or more aggressive slowdown because of Delta, then perhaps others.
What I'd encourage you to think about there is where in the world everybody is exposed and where they are seeing their growth. So in our case, we have a certain regional profile where our procedures are being done. Other companies may have much bigger exposure to say markets or countries that have a lower impact having to do with Delta. Frankly, I think it's as simple as that, but time will tell on that as well.
So let's go ahead and conclude. That was our last question. In closing, we continue to believe there is a substantial and durable opportunity to fundamentally improve surgery and acute interventions.
Our teams continue to work closely with hospitals, physicians, and care teams in pursuit of what our customers have termed a Quadruple Aim: better more predictable patient outcomes, better experiences for patients, better experiences for their care teams, and ultimately a lower total cost of care.
We believe value creation in surgery and acute care is foundationally human. It falls from respect for and understanding of patients and care teams, their needs, and their environment. Thank you for your support on this extraordinary journey. We look forward to speaking with you again in three months.
