Quantifying the Backlog of Total Hip and Knee Arthroplasty Cases: Predicting the Impact of COVID-19

Negative health impacts of navigating the healthcare system for musculoskeletal conditions: A scoping review protocol

Musculoskeletal (MSK) conditions, particularly shoulders, knees, and the low back issues, place a significant burden on individuals, society, and healthcare systems. There is a lack of attention to negative health effects impacting patients because of their interactions to access appropriate diagnostics, assessments, and treatments. This scoping review intends to search and synthesize peer-reviewed evidence on the negative health impacts associated with navigating the healthcare system for MSK care. A scoping review will be conducted following the PRISMA guidelines for Scoping Reviews and Arksey and O'Malley's 5-step process. Six databases will be searched with no time or geographic limits. Included articles must meet all the following criteria: 1) the patients must be adults, 2) patients must be seeking care for their knee, low-back, or shoulder condition, 3) interacted with the healthcare system, and 4) experienced health impacts due to navigating the healthcare system. Information from each article will be charted in a pre-determined extraction. This protocol aims to share our methods ahead of analysis to increase rigour and transparency. The scoping review results will better elucidate the health impacts of the inaccessibility of high-quality care for MSK conditions. The findings also aim to inform the development of patient-centered outcomes to evaluate alterations to the current MSK pathways.

Specialty economies of scope in English hospitals: Cost Arguments for colocation

OBJECTIVE

Current policy responses to COVID-19 disruption and care backlogs suggest potential changes to the location and structure of hospital healthcare supply. However, few studies investigating the cost effects of hospital reorganisation consider changes in the mix of outputs or test for the existence of economies of scope in hospital healthcare. Attempts to create dedicated hubs to address healthcare demand backlogs could have unintended adverse cost effects where these are provided outside existing hospital arrangements. To evaluate this, we investigate the existence and size of economies of scope in English hospital healthcare.

DATA

We use cost and activity data from the English NHS, linked to aggregated staff wage information and information taken from hospital financial statements. Cost and activity data was obtained from NHS England's Costing Publications. Wage data was extracted from the NHS's Electronic Staff Record via the NHS England Workforce Statistics Team, and published hospital financial accounts were aggregated and linked together at the organisation level.

RESULTS

General Surgery exhibited positive economies of scope when provided alongside other healthcare, as to a lesser extent did General Medicine and Obstetric/Gynaecology healthcare. There was little evidence for economies of scope in Diagnostic and Pathology services, Orthopaedics, or Emergency Care. Few (2/28) output cross-products (cost complementarities) were statistically significant, but Baumol's wider definition of scope economies demonstrates that scope economies are present in some specialties.

CONCLUSION

Policymakers seeking to maximise the amount of healthcare provided and minimise the costs of doing so may wish to consider retaining General Surgery, General Medicine and Obstetric/Gynaecology healthcare supply alongside the provision of other clinical specialties. There is limited evidence that reconfiguring supply by centralizing other specialty groups into fewer providers would increase costs.

Impact of the Covid-19 pandemic on inpatient health care in Switzerland 2020-2021-A descriptive retrospective study using admission data of all Swiss hospitals

BACKGROUND

As part of the Covid-19-restrictions in Switzerland, a federal ban on non-urgent examinations and treatments was applied to all hospitals during six weeks in spring 2020 ("spring lockdown"). The aim of this study was to comprehensively investigate the consequences of the Covid-19 pandemic on Swiss inpatient admissions based on data of all hospitals, focusing on selected procedures of different medical urgency.

METHODS

The study includes all acute care inpatient cases (including Covid-19 cases, excluding cases in psychiatry and rehabilitation) according to the Swiss Medical Statistics of Hospitals. Besides the total number of admissions, subdivided by regions, hospital types and age groups, we focused on selected procedures representing different medical urgency: elective surgeries, cancer surgeries, and emergencies. Procedures were selected based on expert interviews. We compared the number of admissions during spring lockdown and for the whole years 2020 and 2021 in absolute numbers and in percentage changes to the corresponding periods in 2019 (baseline year).

RESULTS

During spring lockdown, the number of admissions decreased by 47,156 (32.2%) without catch-up effect by the end of 2020 (-72,817 admissions/-5.8%). With procedure-specific decreases of up to 86%, the decline in admissions was largest for elective surgery, a decline that was only fully reversed in the case of a few procedures, such as joint arthroplasty. Strikingly, admissions due to emergencies also substantially decreased during spring lockdown (stroke -14%; acute myocardial infarction STEMI: -9%, NSTEMI: -26%). Results for the selected procedures in cancer surgery showed no consistent pattern. In 2021, admission numbers for most procedures reached or even exceeded those in 2019.

CONCLUSIONS

The substantial reduction in admissions, particularly in elective procedures, may reflect the impact of the triage in favor of anticipated Covid-19-cases during spring lockdown. By the end of 2020, admissions were still at lower levels relative to the previous, pre-pandemic year. The numbers in 2021 reached the same levels as those in 2019, which suggests that the Covid-19 pandemic only temporarily impacted inpatient health care in Switzerland. Long-term consequences of the observed reduction in admissions for emergencies and cancer surgery need to be investigated at the individual level.

Total Hip and Total Knee Arthroplasty Outpatient Case Volume During the 2020 COVID-19 Pandemic in New York and California

BACKGROUND

Inpatient total hip and total knee arthroplasty were substantially impacted by the SARS-CoV-2 (COVID-19) pandemic. We sought to characterize the transition of total joint arthroplasty (TJA) to the outpatient setting in 2 large state health systems during this pandemic.

METHODS

Adult patients who underwent primary elective TJA between January 1, 2016 and December 31, 2020 were retrospectively reviewed using the New York Statewide Planning and Research Cooperative System and California Department of Health Care Access and Information datasets. Yearly inpatient and outpatient case volumes and patient demographics, including age, sex, race, and payer coverage, were recorded. Continuous and categorical variables were compared using descriptive statistics. Significance was set at P < .05.

RESULTS

In New York during 2020, TJA volume decreased 16% because 22,742 fewer inpatient TJAs were performed. Much of this lost volume (46.6%) was offset by a 166% increase in outpatient TJA. In California during 2020, TJA volume decreased 20% because 34,114 fewer inpatient TJAs were performed. Much of this lost volume (37%) was offset by a 47% increase in outpatient TJA.

CONCLUSIONS

This present study demonstrates a marked increase in the proportion of TJA being performed on an outpatient basis in both California and New York. In both states, despite a decrease in overall TJA volume in 2020, outpatient TJA volume increased markedly.

Cryoneurolysis for the Treatment of Knee Arthritis to Facilitate Inpatient Rehabilitation: A Case Report

A 65-year-old woman presenting with a sensory ganglionopathy complicated with COVID-19 is limited in her rehabilitation due to pain from lateral compartment knee osteoarthritis. To increase participation in rehabilitation, cryoneurolysis of the medial and lateral anterior femoral cutaneous nerve and infrapatellar branches of the saphenous nerve was provided to manage pain associated with knee osteoarthritis. The patient reported immediate relief from pain. Physiotherapy noted improvement immediately after the procedure. Follow-ups at 7- and 11-days post-treatment revealed ongoing increases in mobility and reduction in pain. The patient was discharged to live independently shortly after cryoneurolysis. Cryoneurolysis for knee osteoarthritis could be considered as a treatment option to increase participation in rehabilitation for hospital inpatients who are stalled in their rehabilitation due to pain and poor mobility from knee osteoarthritis.

The Impact of the Coronavirus Disease 2019 Pandemic on US Total Knee and Hip Arthroplasty Procedures in 2020

Background

The coronoavirus disease 2019 (COVID-19) pandemic had profound impact on elective procedures in the United States. We characterized the longer-term decline and recovery of hip and knee arthroplasty procedures following the onset of the COVID-19 pandemic in the United States.

Methods

We conducted a retrospective analysis of patients undergoing primary and revision total knee and hip arthroplasty (TKA and THA) in the United States between 2014 and 2020 using claims from a large national commercial payer data set contaivning deidentified information from patients with commercial health coverage. We calculated the percentage of cases lost by month using a forecast model to predict TKA and THA volumes in the absence of COVID-19. We then calculated the association between COVID-19 positivity rates and THA/TKA procedures by state and month.

Results

There was a large initial decline in procedures, with primary TKA and THA volumes declining by 93.2% and 87.1% in April 2020, respectively, with revisions seeing more modest declines. Cases quickly recovered with volumes exceeding expected levels in summer months. However, cumulative 2020 volumes remained below expected with 9.7% and 7.5% of expected primary TKA and THA cases lost, respectively. Higher state COVID-19 positivity rates were associated with lower primary TKA, THA, and revision knee procedure rates.

Conclusions

After the initial decline in March and April, knee and hip arthroplasty cases resumed quickly; however, by the end of 2020, the annual procedure volume had still not recovered fully. The loss in case volume within states was worse in months with higher COVID-19 positivity rates.

Same-Day Total Joint Arthroplasty in the United States From 2016 to 2020: The Impact of the Medicare Inpatient Only List and the COVID-19 Pandemic

BACKGROUND

Same-day total hip arthroplasty (THA) and total knee arthroplasty (TKA) continue to gain popularity in the United States. The present study sought to quantify recent same-day outpatient trends taking into consideration the COVID-19 pandemic as well as the removal of these procedures from the Medicare inpatient only (IPO) list.

METHODS

Patients undergoing primary elective TKA and THA were identified using the Nationwide Ambulatory Surgery Sample and the National Inpatient Sample from January 1, 2016, to December 31, 2020. The same-day cohort included Nationwide Ambulatory Surgery Sample and National Inpatient Sample patients with a length of stay = 0 days. The inpatient cohort included patients with length of stay ≥1 day. National estimates were extrapolated using weight functions.

RESULTS

From January 2016 to December 2020, the proportion of same-day TKA increased from 1.2 (719) to 62.4% (31,293) and the proportion of same-day THA increased from 2.0 (599) to 54.5% (18,252). Following removal from the Medicare IPO list, same-day TKAs increased from 3.2% (1,895) in December 2017 to 13.8% (9,269) in January 2018, and same-day THAs increased from 10.7% (4,295) in December 2019 to 22.5% (8,708) in January 2020. Between February and March 2020, same-day TKAs increased from 42.4 (26,148) to 44.4% (16,972) and same-day THAs increased from 28.5 (10,729) to 30.2% (7,409).

CONCLUSIONS

The proportion of same-day TKA and THA dramatically increased following removal from the Medicare IPO list and in response to the COVID-19 pandemic. By December 2020, same-day TKA and THA accounted for >50% of all cases performed in the United States.

An Updated Estimate of Total Hip and Total Knee Arthroplasty Inpatient Case Volume During the 2020 COVID-19 Pandemic in the United States

Background

Inpatient total hip arthroplasty (THA) and total knee arthroplasty (TKA) practices were dramatically affected in the United States in 2020 as elective surgeries were paused in response to the COVID-19 pandemic. This study sought to provide an updated estimate of inpatient total joint arthroplasty (TJA) case volumes in the United States in 2020.

Methods

A retrospective cohort study was performed by identifying all adult patients who underwent primary, elective TJA from January 1st, 2017 to December 31st, 2020, using the National Inpatient Sample. Monthly and annual case volumes were reported with descriptive statistics. Baseline case volumes were established by taking the average number of monthly cases performed in 2017, 2018, and 2019. These monthly averages were compared to 2020 values.

Results

From 2017 to 2019, the average case volume was 1,056,669 cases per year (41.0% THA, 59.0% TKA) and 88,055 cases per month. In 2020, 535,441 cases were identified (45.4% THA, 54.6% TKA), corresponding to a 49.3% reduction from the 2017-2019 annual average. Monthly cases decreased to 4515 in April during the "first wave" of COVID-19, corresponding to a 94.8% decrease from prior years. In June, cases rebounded to 55,520 before decreasing again in July to 50,100 during the "second wave" of COVID-19. During the "third wave," COVID-19 cases decreased month-over-month from October through December (56.5% decrease).

Conclusions

This updated estimate identified a 49.3% decrease in inpatient TJA cases in 2020 compared to prior years. This is similar to the 46.5-47.7% decrease in case volume previously reported.

Impact of the coronavirus disease 2019 pandemic on equity of access to hip and knee replacements: a population-level study

PURPOSE

The COVID-19 pandemic had innumerable impacts on healthcare delivery. In Canada, this included limitations on inpatient capacity, which resulted in an increased focus on outpatient surgery for non-emergent cases such as joint replacements. The objective of this study was to assess whether the pandemic and the shift towards outpatient surgery had an impact on access to joint replacement for marginalized patients.

METHODS

Data from Ontario's administrative healthcare databases were obtained for all patients undergoing an elective hip or knee replacement between January 1, 2018 and August 31, 2021. All surgeries performed before March 15, 2020 were classified as "pre-COVID," while all procedures performed after that date were classified as "post-COVID." The Ontario Marginalization Index domains were used to analyze proportion of marginalized patients undergoing surgery pre- and post-COVID.

RESULTS

A total of 102,743 patients were included-42,812 hip replacements and 59,931 knee replacements. There was a significant shift towards outpatient surgery during the post-COVID period (1.1% of all cases pre-COVID to 13.2% post-COVID, p < 0.001). In the post-COVID cohort, there were significantly fewer patients from some marginalized groups, as well as fewer patients with certain co-morbidities, such as congestive heart failure and chronic obstructive pulmonary disease.

CONCLUSION

The most important finding of this population-level database study is that, compared to before the COVID-19 pandemic, there has been a change in the profile of patients undergoing hip and knee replacements in Ontario, specifically across a range of indicators. Fewer marginalized patients are undergoing joint replacement surgery since the COVID-19 pandemic. Further monitoring of access to joint replacement surgery is required in order to ensure that surgery is provided to those who are most in need.

Development of a machine learning algorithm to identify surgical candidates for hip and knee arthroplasty without in-person evaluation

INTRODUCTION

Arthroplasty care delivery is facing a growing supply-demand mismatch. To meet future demand for joint arthroplasty, systems will need to identify potential surgical candidates prior to evaluation by orthopaedic surgeons.

MATERIALS AND METHODS

Retrospective review was conducted at two academic medical centers and three community hospitals from March 1 to July 31, 2020 to identify new patient telemedicine encounters (without prior in-person evaluation) for consideration of hip or knee arthroplasty. The primary outcome was surgical indication for joint replacement. Five machine learning algorithms were developed to predict likelihood of surgical indication and assessed by discrimination, calibration, overall performance, and decision curve analysis.

RESULTS

Overall, 158 patients underwent new patient telemedicine evaluation for consideration of THA, TKA, or UKA and 65.2% (n = 103) were indicated for operative intervention prior to in-person evaluation. The median age was 65 (interquartile range 59-70) and 60.8% were women. Variables found to be associated with operative intervention were radiographic degree of arthritis, prior trial of intra-articular injection, trial of physical therapy, opioid use, and tobacco use. In the independent testing set (n = 46) not used for algorithm development, the stochastic gradient boosting algorithm achieved the best performance with AUC 0.83, calibration intercept 0.13, calibration slope 1.03, Brier score 0.15 relative to a null model Brier score of 0.23, and higher net benefit than the default alternatives on decision curve analysis.

CONCLUSION

We developed a machine learning algorithm to identify potential surgical candidates for joint arthroplasty in the setting of osteoarthritis without an in-person evaluation or physical examination. If externally validated, this algorithm could be deployed by various stakeholders, including patients, providers, and health systems, to direct appropriate next steps in patients with osteoarthritis and improve efficiency in identifying surgical candidates.

Elective Joint Arthroplasty Should be Delayed by One Month After COVID-19 Infection to Prevent Postoperative Complications

BACKGROUND

It remains unclear whether a history of recent COVID-19 infection affects the outcomes and risks of complications of total joint arthroplasty (TJA). The purpose of this study was to compare the outcomes of TJA in patients who have and have not had a recent COVID-19 infection.

METHODS

A large national database was queried for patients undergoing total hip and total knee arthroplasty. Patients who had a diagnosis of COVID-19 within 90-days preoperatively were matched to patients who did not have a history of COVID-19 based on age, sex, Charlson Comorbidity Index, and procedure. A total of 31,453 patients undergoing TJA were identified, of which 616 (2.0%) had a preoperative diagnosis of COVID-19. Of these, 281 COVID-19 positive patients were matched with 281 patients who did not have COVID-19. The 90-day complications were compared between patients who did and did not have a diagnosis of COVID-19 at 1, 2, and 3 months preoperatively. Multivariate analyses were used to further control for potential confounders.

RESULTS

Multivariate analysis of the matched cohorts showed that COVID-19 infection within 1 month prior to TJA was associated with an increased rate of postoperative deep vein thrombosis (odds ratio [OR]: 6.50, 95% confidence interval: 1.48-28.45, P = .010) and venous thromboembolic events (odds ratio: 8.32, confidence interval: 2.12-34.84, P = .002). COVID-19 infection within 2 and 3 months prior to TJA did not significantly affect outcomes.

CONCLUSION

COVID-19 infection within 1 month prior to TJA significantly increases the risk of postoperative thromboembolic events; however, complication rates returned to baseline after that time point. Surgeons should consider delaying elective total hip arthroplasty and total knee arthroplasty until 1 month after a COVID-19 infection.

A reinforcement learning-based optimal control approach for managing an elective surgery backlog after pandemic disruption

Contagious disease pandemics, such as COVID-19, can cause hospitals around the world to delay nonemergent elective surgeries, which results in a large surgery backlog. To develop an operational solution for providing patients timely surgical care with limited health care resources, this study proposes a stochastic control process-based method that helps hospitals make operational recovery plans to clear their surgery backlog and restore surgical activity safely. The elective surgery backlog recovery process is modeled by a general discrete-time queueing network system, which is formulated by a Markov decision process. A scheduling optimization algorithm based on the piecewise decaying [Formula: see text]-greedy reinforcement learning algorithm is proposed to make dynamic daily surgery scheduling plans considering newly arrived patients, waiting time and clinical urgency. The proposed method is tested through a set of simulated dataset, and implemented on an elective surgery backlog that built up in one large general hospital in China after the outbreak of COVID-19. The results show that, compared with the current policy, the proposed method can effectively and rapidly clear the surgery backlog caused by a pandemic while ensuring that all patients receive timely surgical care. These results encourage the wider adoption of the proposed method to manage surgery scheduling during all phases of a public health crisis.

Challenges with patient management of osteoarthritis during the COVID-19 pandemic: review

Osteoarthritis is a growing public health concern, affecting millions of people worldwide. With progressively worsening joint function and pain, management of osteoarthritis is important to ensure high quality of life for patients. Treatment includes a combination of pharmacologic agents and non-pharmacologic methods such as exercise and physical therapy. However, if multiple treatments fail to improve symptoms, joint replacement surgery is the final course of action. When the new coronavirus, SARS-CoV-2 (COVID-19), was declared a pandemic, all aspects of osteoarthritis treatment become affected. Due to increased public health measures, non-pharmacologic modalities and elective surgeries became limited in accessibility. Additionally, there were concerns about the interaction of current medications for osteoarthritis with the virus. As a result of limited options for treatment and quality of life of patients was negatively impacted, especially in those with severe osteoarthritis. Furthermore, a backlog of joint replacement surgeries was created which could take up to several months or years to address. In this review, we describe the impact COVID-19 had on osteoarthritis management as well as tactics to deal with the large caseload of surgeries as operative rooms begin to re-open for elective surgeries.

Changes Over a Decade in Patient-Reported Outcome Measures and Minimal Clinically Important Difference Reporting in Total Joint Arthroplasty

Background

When used appropriately, the minimal clinically important difference (MCID) provides a powerful tool for identifying meaningful improvements brought about by a given treatment, offering more clinically relevant information than frequentist statistical analysis. However, recent studies have shown inconsistent derivation methods and use of MCIDs. The goal of this study was to report the rate of patient-reported outcome measures (PROMs) and MCIDs use in the literature and assess how this rate has changed over time.

Methods

All articles published in 2010 and 2020 reporting on total hip arthroplasty or total knee arthroplasty in The Journal of Clinical Orthopaedics and Related Research, The Journal of Bone and Joint Surgery, and The Journal of Arthroplasty were reviewed. In each reviewed article, every reported PROM and, if present, its corresponding MCID was recorded. These data were used to calculate the rate of reporting of each PROM and MCID.

Results

While the total number of articles on total hip arthroplasty and total knee arthroplasty reporting PROMs increased over time, the proportion of articles reporting PROMs decreased from 49.8% (131/263) in 2010 to 35.5% (194/546) in 2020 (P = .011). Of these articles that report PROMs, the proportion of articles reporting any MCID increased from 2.3% (3/131) in 2010 to 16.5% (32/194) in 2020 (P = .002).

Conclusions

The rate of reporting of MCIDs among articles relating to total hip arthroplasty and total knee arthroplasty that report PROMs has increased significantly between 2010 and 2020 but remains low. Continued emphasis on appropriate inclusion and value of MCIDs when PROMS are reported in clinical outcomes studies is needed.

Impact of the COVID-19 Pandemic on Patient Satisfaction After Total Joint Arthroplasty

The coronavirus disease 2019 (COVID-19) pandemic impacted the inpatient experience before and after total joint arthroplasty (TJA). This study aimed to examine how these changes affected patient satisfaction following TJA as recorded by Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) postdischarge surveys and comments at 2 large academic institutions. A retrospective review identified patients who completed HCAHPS surveys following primary and revision TJA at 2 academic institutions: 1 in a predominately rural southern state (Institution A) and 1 in a northeastern metropolitan city (Institution B). Patients were grouped by discharge date: pre-COVID-19 (April 1, 2019, to October 31, 2019) or COVID-19 affected (April 1, 2020, to October 31, 2020). Differences in demographics, survey responses, and comment sentiments and themes were collected and evaluated. The number of HCAHPS surveys completed increased between periods at Institution A but decreased at Institution B (Institution A, 61 vs 103; Institution B, 524 vs 296). Rates of top-box survey responses remained the same across the 2 periods. The number of comments decreased at Institution B (1977 vs 1012) but increased at Institution A (55 vs 88). During the COVID-19-affected period, there was a significant increase in the negative comment rate from Institution B (11.6% vs 14.8%, P=.013) and a significant decrease in the positive comment rate from Institution A (70.9% vs 44.3%, P<.001). There was an increase in negative patient sentiments following TJA during the COVID-19 pandemic as seen in qualitative comments but not quantitative responses. This suggests that certain aspects of the TJA patient experience were impacted by COVID-19. [Orthopedics. 2023;46(2):e105-e110.].

An Investigation for Future Practice of Elective Hip and Knee Arthroplasties during COVID-19 in Romania

Background and Objectives: Elective arthroplasty in Romania has been severely affected by the COVID-19 pandemic, and its effects are not quantified so far. The aim of this paper is to determine the impact of COVID-19 on arthroplasty interventions and how they varied in Romania. Materials and Methods: We performed a national retrospective analysis of patients who underwent primary and revision elective hip and knee interventions at the 120 orthopedic-traumatology hospitals in Romania that are registered in the National Endoprosthesis Registry from 1 January 2019 to 1 September 2022. First, we examined the monthly trend in the number of surgeries for seven categories of arthroplasties. We calculated the percentage change in the average number of cases per month and compared them with other types of interventions. We then examined the percentage change in the average monthly number of arthroplasty cases, relative to the number of COVID-19 cases reported nationwide, the influence of the pandemic on length of hospital stay, and the percentage of patients discharged at home who no longer follow recovery protocols. Finally, we calculated the impact of the pandemic on hospital revenues. Results: There was an abrupt decrease in the volume of primary interventions in hip and knee patients by up to 69.14% with a low degree of patient care, while the average duration of scheduled hospitalizations increased. We found a 1-2-day decrease in length of hospital stays for explored arthroplasties. We saw an increasing trend of home discharge, which was higher for primary interventions compared to revision interventions. The total hospital revenues were 50.96% lower in 2020 compared to 2019, and are currently increasing, with the 2022 estimate being 81.46%. Conclusions: The conclusion of this study is that the COVID-19 pandemic severely affected the volume of arthroplasty of the 120 hospitals in Romania, which also had unfavorable financial implications. We proposed the development of new procedures and alternative clinical solutions, as well as personalized home recovery programs, to be activated if necessary, for possible future outbreaks.

Inflation-Adjusted Medicare Reimbursement for Hip Arthroscopy Fell by 21.1% on Average Between 2011 and 2022

Purpose

To examine Medicare reimbursement for hip arthroscopy from 2011 to 2022.

Methods

The seven most common procedures performed with hip arthroscopy by a single surgeon were gathered. The Physician Fee Schedule Look-Up Tool was utilized to access financial data of the associated Current Procedural Terminology (CPT) codes. The reimbursement data for each CPT were gathered from the Physician Fee Schedule Look-Up Tool. With the consumer price index database and inflation calculator, reimbursement values were adjusted for inflation to 2022 U.S. dollars.

Results

Following an adjustment for inflation, it was found that reimbursement rate for hip arthroscopy procedures on average was 21.1% lower between 2011 and 2022. The average reimbursement per CPT code for the included codes was $899.21 in 2022 compared to inflation adjusted $1,141.45 in 2011, a difference of $242.24.

Conclusions

From 2011 to 2022, the average inflation-adjusted Medicare reimbursement has steadily declined for the most common hip arthroscopy procedures. As Medicare is one of the largest insurance payers, these results have substantial financial and clinical implications for orthopaedic surgeons, policy makers, and patients.

The Effect of COVID-19 on Elective Total Knee Arthroplasty Utilization, Patient Comorbidity Burden, and Complications in the United States: A Nationwide Analysis

INTRODUCTION

Total knee arthroplasty (TKA) is one of the highest volume elective procedures done nationwide. Elective surgery was suspended because of the COVID-19 pandemic. The utilization trends, comparison of patient demographics, and postoperative outcomes in 2020 have yet to be evaluated substantially. We compared temporal trends in procedural volume, patient demographics, and postoperative complications of elective TKA in 2019 and 2020.

METHODS

Using a multicenter, nationwide representative sample, a retrospective query of the 2019 to 2020 American College of Surgeon's National Surgery Quality Improvement Program database was conducted for patients undergoing elective TKA. Temporal trends in utilization, demographics, and length of stay were compared pre-COVID-19 (2019 to 2020Q1) with post-COVID-19 (2020Q2 to Q4). Postoperative outcomes were compared by calendar year (2019 versus 2020). Linear regression was used to evaluate changes in procedural volume over time. A significance threshold of P < 0.05 was used.

RESULTS

A total of 121,415 patients underwent elective TKA in 2019 (N = 72,002) and 2020 (N = 49,413), a 31.4% decline. The proportion of hospital-defined "outpatient" TKAs in 2020 was significantly greater than that in 2019 (41.5% versus 25.5%; P < 0.001). Elective TKA utilization declined by 65.1% in 2020Q2 and never returned to prepandemic baseline in 2020Q3 to Q4. The average length of stay was shorter in 2020 (1.56 versus 1.87 days; P < 0.001). The proportion of same-day discharge increased each quarter from 2019Q1 to Q4 (6.2% to 8.6%) to 2020Q1 to Q4 (8.7% to 17.1%). Total complication rates were similar in 2019 (4.84%) versus 2020 (4.75%); P = 0.430. The 30-day mortality (0.08% versus 0.07%; P = 0.858), revision surgery (1.0% versus 1.0%; P = 0.940), and readmission (2.8% versus 2.6%; P = 0.053) rates were no different between 2019 and 2020.

CONCLUSION

Elective TKA declined during the second quarter of 2020. A large proportion of surgeries were transitioned to outpatient with rates of same-day discharge increasing over the study period, despite no change in complication, mortality, and readmission rates. Patient outcomes were not compromised despite pandemic restrictions for elective surgery.

The combined effect of policy changes and the covid-19 pandemic on the same day discharge and complications following total hip arthroplasty: a nationwide analysis

Introduction

As a result of the SARS-CoV-2 (COVID-19) pandemic in 2020, elective surgeries, including total joint arthroplasty (TJA), were suspended nationwide. Concurrent removal of total hip arthroplasty (THA) from the Medicare inpatient-only list posed challenges to the delivery of quality patient care with low payor cost. Therefore, the objective of this study was to compare temporal trends in patient demographics, case volumes, length of stay, and complications following elective THA in the years 2019 to 2020 in the United States.

Methods

The 2019 to 2020 ACS-NSQIP database was queried for elective THA patients. Patients Pre-COVID (2019 and 2020Q1) were compared with post-COVID (2020Q2-Q4). THA utilization, demographics, 30-day complications, and length of stay (LOS) were compared between years. Linear regression evaluated changes in case volumes over time with significance threshold of P < 0.05.

Results

A total of 77,797 patients underwent elective THA in 2019 (n = 43,667) and 2020 (n = 34,130), resulting in a 24.5% decline. Outpatient THA increased in 2020 (35.6%) vs. 2019 (5.7%) (P < 0.001). There was no significant difference in the volume of cases in 2019Q1 through 2019Q4 (P = 0.984). Elective THA volumes declined by 68.8% in 2020Q2, returned to pre-pandemic baseline in 2020Q3, before leveling off at 81.5% of baseline in Q4. Average LOS was significantly shorter in 2020 (1.55 days) vs. 2019 (1.78 days) (P < 0.001) and the proportion of same day discharge (SDD) increased quarterly from 2019 to 2020. There was no significant difference in the total complication rates in 2019 (6.6%) vs. 2020 (6.6%) (P = 0.831).

Discussion

Elective THA precipitously declined during the second quarter of 2020. The combined effect of policy changes and the COVID-19 pandemic resulted in a seven-fold increase in the number of surgeries performed in the outpatient setting in 2020. Rates of SDD doubled over the study period, despite no change in complication rates.

No time to waste; the impact of the COVID-19 pandemic on hip, knee, and shoulder arthroplasty surgeries in the Netherlands and Denmark

AIMS

This study aimed to investigate the estimated change in primary and revision arthroplasty rate in the Netherlands and Denmark for hips, knees, and shoulders during the COVID-19 pandemic in 2020 (COVID-period). Additional points of focus included the comparison of patient characteristics and hospital type (2019 vs COVID-period), and the estimated loss of quality-adjusted life years (QALYs) and impact on waiting lists.

METHODS

All hip, knee, and shoulder arthroplasties (2014 to 2020) from the Dutch Arthroplasty Register, and hip and knee arthroplasties from the Danish Hip and Knee Arthroplasty Registries, were included. The expected number of arthroplasties per month in 2020 was estimated using Poisson regression, taking into account changes in age and sex distribution of the general Dutch/Danish population over time, calculating observed/expected (O/E) ratios. Country-specific proportions of patient characteristics and hospital type were calculated per indication category (osteoarthritis/other elective/acute). Waiting list outcomes including QALYs were estimated by modelling virtual waiting lists including 0%, 5% and 10% extra capacity.

RESULTS

During COVID-period, fewer arthroplasties were performed than expected (Netherlands: 20%; Denmark: 5%), with the lowest O/E in April. In the Netherlands, more acute indications were prioritized, resulting in more American Society of Anesthesiologists grade III to IV patients receiving surgery. In both countries, no other patient prioritization was present. Relatively more arthroplasties were performed in private hospitals. There were no clinically relevant differences in revision arthroplasties between pre-COVID and COVID-period. Estimated total health loss depending on extra capacity ranged from: 19,800 to 29,400 QALYs (Netherlands): 1,700 to 2,400 QALYs (Denmark). With no extra capacity it will take > 30 years to deplete the waiting lists.

CONCLUSION

The COVID-19 pandemic had an enormous negative effect on arthroplasty rates, but more in the Netherlands than Denmark. In the Netherlands, hip and shoulder patients with acute indications were prioritized. Private hospitals filled in part of the capacity gap. QALY loss due to postponed arthroplasty surgeries is considerable.Cite this article: Bone Jt Open 2022;3(12):977-990.

Second and Third Pandemic Waves in Apulia: How COVID-19 Affected Orthopedic and Trauma Care-A Single-Center Study

PURPOSE

In orthopedics and traumatology, as a direct consequence of the COVID-19 first wave, there was a massive reorganization and a stop to all elective activities, which were postponed. In this study, we aimed to analyze the impact of the COVID-19 pandemic on orthopedic surgery in Apulia during the second wave, from March to June 2021 (when Apulia was under social distancing restrictions), and during the third wave, from September to December 2021 (when Apulia was under no restrictions). We compared these months to the same periods in 2019 for an evaluation of the surgical decrease during the pandemic period.

METHODS

We performed a retrospective analysis of major orthopedic procedures, day-surgery procedures and urgent procedures (trauma and non-traumatic amputation) performed during the second and third waves of the pandemic in our clinic, and we compared these data with the same procedures performed in the corresponding periods of 2019, before the pandemic.

RESULTS

Surgical activity was significantly decreased during both periods; the only increase in surgical activity in 2021 compared to 2019 was in total hip, knee and shoulder arthroplasty, with a surge of +7.69% registered in the period September-December 2021.

CONCLUSIONS

Longer waiting lists and limited healthcare resources were the big challenges for the orthopedic community, and they still represent a substantial issue to confront today.

Comparison of total joint arthroplasty care patterns prior to the Covid-19 pandemic and after resumption of elective surgery during the Covid-19 Outbreak: A retrospective, large urban academic center study

BACKGROUND

After the suspension of elective surgeries was lifted in June 2020 in New York State, challenges remained regarding coordination of total joint arthroplasty (TJA) cases. Using the experience from a high-volume health system in New York City, we aimed to describe patterns of care after resumption of elective TJA.

METHODS

We retrospectively assessed 7,699 TJAs performed before and during the COVID-19 pandemic. Perioperative characteristics and clinical outcomes were compared between TJAs based on time period of performance: 1) pre-pandemic (PP, June 8th-December 8th, 2019), 2) initial period post-resumption of elective surgeries (IR, June 8th-September 8th, 2020), and 3) later period post-resumption (LR, September 9th-December 8th, 2020).

RESULTS

LOS > 2 days (83%, 67%, 70% for PP, IR, LR periods respectively) and discharge rates to post-acute care (PAC) facilities were lower during the pandemic periods (OR_{IR vs. PP}: 0.48, 95% CI: 0.40-0.59, p < 0.001; OR_{LR vs. PP}: 0.63, 95% CI: 0.53-0.75, p < 0.001). Compared to the pre-pandemic period, the risk for 30-day readmission was lower during the IR period (OR: 0.62, 95% CI: 0.40-0.98, p = 0.041) and similar during the LR period (OR: 0.96, 95% CI: 0.65-1.41, p = 0.832).

CONCLUSIONS

Despite decreased LOS and discharge to PAC for TJAs performed during the pandemic, 30-day readmissions did not increase. Given the increased costs and lack of superior functional outcomes associated with discharge to PAC, these findings suggest that discharge to PAC facilities need not return to pre-pandemic levels.

Same-Day Discharge Following Aseptic Revision and Conversion Total Joint Arthroplasty: A Single-Institution Experience

Background

With hospital inpatient capacity increasingly limited and primary total joint arthroplasty (TJA) rapidly transitioning to outpatient settings, the feasibility of outpatient aseptic revision and conversion TJA (rTJA) has been considered. Before the widespread adoption of outpatient rTJA, guidelines must be established to prevent patient harm. To this end, this study describes our initial experience with same-day-discharge (SDD) aseptic rTJA.

Methods

All aseptic rTJAs performed between May 8, 2015, and December 30, 2021, were retrospectively reviewed. Revision indications, patient selection criteria, and outcomes including SDD success rate, predischarge complications, all-cause emergency department visits, inpatient readmissions, and unplanned clinic encounters within 90 days of surgery were recorded.

Results

Thirty-five SDD aseptic rTJAs were performed. Conversion total hip arthroplasty (55.0%) and instability (27.3%) were the most common indications for hip revision. Instability (50%) and conversion total knee arthroplasty (20.8%) were most common for knee revision. SDD was achieved in 97% (34/35) of cases. One hip patient failed SDD due to persistent hypoxia requiring an overnight hospital stay and also underwent closed reduction for dislocation in the emergency department within 90 days of discharge. Two additional patients had unplanned clinic encounters within 90 days of the index procedure. There were no hospital readmissions or reoperations within 90 days.

Conclusions

Our initial experience suggests SDD aseptic rTJA can be safe and effective when modern perioperative outpatient protocols and surgical techniques are implemented. Future studies should further define patient selection criteria to optimize outcomes and minimize complications in this population.

IMPACT OF MEASURES TO FIGHT THE PANDEMIC COVID-19 ON KNEE ARTHROPLASTIES IN BRAZIL

Objective

To assess the impacts of measures to face COVID-19 on total knee arthroplasty procedures in the country, based on data provided by the SUS Information and Informatics Department (DATASUS).

Methods

Cross-sectional study of secondary data in the public domain, available on the website of the Department of Information and Informatics of SUS (DATASUS), containing information about hospital admissions in the SUS.

Results

Brazil suffered a 51.82% decrease, on average, in the performance of total knee arthroplasty by the Unified Health System (SUS) in 2020, due to measures to face COVID-19. The analysis by region offers more details on this reduction in the number of procedures. In the Northeast, the decrease was on average 48.02%, whereas in the Center-West it was 65.61%. Southeast, North, and South registered an average decrease of 49.38%, 51.81%, and 55.06%, respectively.

Conclusion

COVID-19 impacted the realization of TKA in Brazil, with greater and lesser levels of decline observed in different Brazilian regions. In the Southeast region, for example, the states of São Paulo and Minas Gerais were the most affected, mainly due to the large population concentration, as well as Paraná, which has high numbers of procedures and a sharp decrease in 2020.

Elective Inpatient Total Joint Arthroplasty Case Volume in the United States in 2020: Effects of the COVID-19 Pandemic

BACKGROUND

Despite known surgical volume reductions in 2020 during the height of the COVID-19 pandemic, no study has fully quantified the impact of the pandemic on the number of elective inpatient total hip (THA) and total knee arthroplasty (TKA) cases. The purpose of the present study was to analyze THA and TKA case volumes in the United States during the COVID-19 pandemic.

METHODS

The Premier Healthcare Database was utilized to identify adults undergoing primary elective THA or TKA from January 2017 to December 2020. The National Inpatient Sample was cross-referenced to provide nationwide representative sampling weights. Patients undergoing revision total joint arthroplasty (TJA) or non-elective surgery were excluded. Two quantitative models were created from both databases to estimate TJA case volume in 2020. Descriptive statistics were utilized to report monthly changes in elective TJA utilization throughout 2020. Univariate analyses were performed to compare differences between subgroups.

RESULTS

From 2017 to 2019, it was estimated that 1,006,000 elective inpatient TJAs (64.2% TKA and 35.8% THA) were performed annually. In 2020, an estimated 526,000 to 538,000 cases (62.0% TKA and 38.0% THA) were performed, representing a 46.5% to 47.7% decrease in nationwide volume from the prior 3-year average. Moreover, the elective TJA case volume for April 2020 was 1.9% of the average for that month from 2017 through 2019. Subsequently, case volumes for May and June increased compared with the volumes for those months from 2017 through 2019. There was then a decrease in cases for July, corresponding with the "second wave" of COVID-19, followed by an additional steady monthly decline through December, corresponding with the "third wave." Finally, the elective TJA cases for December 2020 represented only 41.0% of the average case volume for that month from 2017 through 2019.

CONCLUSIONS

In the midst of the 2020 COVID-19 pandemic, approximately 526,000 to 538,000 elective inpatient TJA cases were performed, representing a 46.5% to 47.7% decrease compared with the 3 previous years. The effects of the COVID-19 pandemic persisted through the end of that year, with decreased case volume through December 2020.

Autologous versus synthetic bone grafts for the surgical management of tibial plateau fractures: a systematic review and meta-analysis of randomized controlled trials

AIMS

Our objective was to conduct a systematic review and meta-analysis, to establish whether differences arise in clinical outcomes between autologous and synthetic bone grafts in the operative management of tibial plateau fractures.

METHODS

A structured search of MEDLINE, EMBASE, the online archives of Bone & Joint Publishing, and CENTRAL databases from inception until 28 July 2021 was performed. Randomized, controlled, clinical trials that compared autologous and synthetic bone grafts in tibial plateau fractures were included. Preclinical studies, clinical studies in paediatric patients, pathological fractures, fracture nonunion, or chondral defects were excluded. Outcome data were assessed using the Risk of Bias 2 (ROB2) framework and synthesized in random-effect meta-analysis. The Preferred Reported Items for Systematic Review and Meta-Analyses guidance was followed throughout.

RESULTS

Six studies involving 353 fractures were identified from 3,078 records. Following ROB2 assessment, five studies (representing 338 fractures) were appropriate for meta-analysis. Primary outcomes showed non-significant reductions in articular depression at immediate postoperative (mean difference -0.45 mm, p = 0.25, 95%confidence interval (CI) -1.21 to 0.31, I2 = 0%) and long-term (> six months, standard mean difference -0.56, p = 0.09, 95% CI -1.20 to 0.08, I2 = 73%) follow-up in synthetic bone grafts. Secondary outcomes included mechanical alignment, limb functionality, and defect site pain at long-term follow-up, perioperative blood loss, duration of surgery, occurrence of surgical site infections, and secondary surgery. Mean blood loss was lower (90.08 ml, p < 0.001, 95% CI 41.49 to 138.67) and surgery was shorter (16.17 minutes, p = 0.04, 95% CI 0.39 to 31.94) in synthetic treatment groups. All other secondary measures were statistically comparable.

CONCLUSION

All studies reported similar methodologies and patient populations; however, imprecision may have arisen through performance variation. These findings supersede previous literature and indicate that, despite perceived biological advantages, autologous bone grafting does not demonstrate superiority to synthetic grafts. When selecting a void filler, surgeons should consider patient comorbidity, environmental and societal factors in provision, and perioperative and postoperative care provision.

The effect of the COVID-19 pandemic on revision total hip and knee arthroplasty at a large academic hospital network

We sought to quantify the impact of COVID-19 on canceled revision total joint arthroplasty (TJA) in a large academic hospital network. We performed a retrospective analysis of revision TKA and THA in a healthcare system containing 5 hospitals in a time period of 8 months prior to and 8 months after the cessation of elective surgery. We found a 30.1% decrease in revision TKA and a 6.80% decrease in revision THA. Revision TJA volume decreased in our healthcare system during COVID-19 compared to prior to the pandemic, which will likely have lasting financial and clinical ramifications for the healthcare system.

Comparing ERAS-outpatient versus standard-inpatient hip and knee replacements: a mixed methods study exploring the experience of patients who underwent both

BACKGROUND

Optimizing patients' total hip and knee arthroplasty (THA/TKA) experience is as crucial for providing high quality care as improving safety and clinical effectiveness. Yet, little evidence is available on patient experience in standard-inpatient and enhanced recovery after surgery (ERAS)-outpatient programs. Therefore, this study aimed to gain a more in-depth understanding of the patient experience of ERAS-outpatient programs in comparison to standard-inpatient programs.

METHODS

We conducted a convergent mixed methods study of 48 consecutive patients who experienced both standard-inpatient and ERAS-outpatient THA/TKA contralaterally. A reflective thematic analysis was conducted based on data collected via a questionnaire. Bivariate correlations between the patient experience and patients' characteristics, clinical outcomes and care components satisfaction were performed. Then, the quantitative and qualitative data were integrated together.

RESULTS

The theme Support makes the difference for better and for worse was identified by patients as crucial to their experience in both joint replacement programs. On the other hand, patients identified 3 themes distinguishing their ERAS-outpatient from their standard-inpatient experience: 1) Minimizing inconvenience, 2) Home sweet home and 3) Returning to normal function and activities. Potential optimization expressed by patients were to receive more preoperative information, additional postoperative rehabilitation sessions, and ensuring better coherence of care between hospital and home care teams. Weak to moderate positive and statistically significant correlations were found between patients' THA/TKA experience and satisfaction with pain management, hospital stay, postoperative recovery, home care, and overall results (rs = + [0.36-0.66], p-value < 0.01).

CONCLUSION

Whatever the perioperative program, the key to improving patients' THA/TKA experience lies in improving support throughout the care episode. However, compared to standard-inpatient care, the ERAS-outpatient program improves patients' experience by providing dedicated support in postoperative care, reducing postoperative inconvenience, optimizing pain management, returning home sooner, and recovering and regaining function sooner. Patients' THA/TKA experience could further be enhanced by optimizing the information provided to the patient, the rehabilitation program and the coherence between care teams.

Management of Outpatient Elective Surgery for Arthroplasty and Sports Medicine During the COVID-19 Pandemic: A Scoping Review

Background:

The onset of the coronavirus disease 2019 (COVID-19) pandemic has presented unforeseeable challenges to the orthopaedic community, especially arthroplasty and sports medicine subspecialities, as many surgeries were deemed nonessential and delayed. Although there is a glimpse of hope with the approval and distribution of vaccines, daily case numbers and death tolls continue to rise at the time of this review.

Purpose:

To summarize the available literature on the management of elective sports medicine and arthroplasty procedures in the outpatient setting to gather a consolidated source of information.

Study Design:

Scoping review; Level of evidence, 5.

Methods:

A scoping review of 3 databases (PubMed, Embase, and OVID Medline) was performed using the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) checklist. All retrospective and prospective analyses, systematic reviews and meta-analyses, expert opinions, and societal guidelines were included for review, with 29 articles meeting the inclusion criteria.

Results:

Guidance for resumption of elective arthroplasty and sports medicine surgery and patient selection during the COVID-19 pandemic focuses on resource availability, patient fitness, and time sensitivity of the procedure, with patient and surgical team safety as the highest priority. Telemedicine and other innovative technology can be used to continue patient care during periods of delayed surgery through monitoring disease progression and offering nonoperative management options.

Conclusion:

While the current societal recommendations provide guidance on safety protocols and patient prioritization, each orthopaedic practice must consider its unique situation and use evidence-based medicine when determining surgical timing and patient selection.

The Impact of COVID-19 on Medical Device Reporting and Investigation

Introduction The Manufacturer and User Facility Device Experience (MAUDE) database houses medical device reports submitted to the U.S. Food and Drug Administration (FDA). In May 2020, the FDA released guidance about medical device reporting during a pandemic, anticipating delays in reporting and investigating events involving medical devices. Methods We aimed to understand how the COVID-19 pandemic impacted medical device reporting by analyzing reports in the MAUDE database that mention COVID-19. Results From the 816,470 reports submitted between January 1 and July 31, 2020, 3,500 (0.43%) included phrases related to COVID-19. Of these reports, 4.8% (167/3,500) described adverse events during COVID-19 patients’ treatment, and 90.3% (3,161 /3,500) described barriers manufacturers faced investigating malfunctioning devices during the pandemic. 4.9% (172/3,500) of reports were not related to COVID-19. Malfunctions were clinically significant in 85.8% (3,004/3,500) of reports. Discussion Reports indicate challenges some manufacturers had when investigating medical devices during the pandemic. The pandemic made investigating implants uniquely difficult, as restrictions to person-to-person contact limited the type of care patients could receive. Because full-scale investigations into malfunctioning devices may be difficult to perform during the pandemic, safety issues may go unaddressed and result in future harm to patients. Conclusion The COVID-19 pandemic and the myriad of healthcare, travel, and shipping challenges it created impacted how manufacturers reported and investigated medical devices. At the current time, it is unclear how manufacturers will address delayed clinical management of implant devices and other uninvestigated malfunctions after the pandemic and how this will impact patient safety.

The Effect of the COVID-19 Pandemic on Total Hip and Knee Arthroplasty Surgical Volume in 2020 in Poland

The aim of this study was to analyse the effect of the first year of the COVID-19 pandemic on total hip arthroplasty (THA) and total knee arthroplasty (TKA) surgical volume in Poland. A retrospective analysis of data concerning THA and TKA collected by the National Health Fund in Poland in 2019 and in 2020 has been conducted. The number of primary hip or knee arthroplasties in 2020 was around 71% and 67% of the number registered in 2019, respectively. There was also a decline in the volume of revision arthroplasties observed, with 65% and 63% of THA and TKA revisions performed in 2019. The most significant decrease was observed in April and May, and during the second wave of the pandemic in November 2020, with a decline of 87%, 55% and 56%, respectively. The results of this study show the significant impacts that the COVID-19 pandemic had on the volume of elective hip and knee arthroplasties in Poland in 2020. In comparison with 2019, a decrease of around 30% for primary and of 40% for revision arthroplasties was observed. The most significant decline was observed in April and May 2020, and during the second wave of the COVID-19 pandemic in Poland in November 2020.

The Initial Impact of COVID-19 on Total Hip and Knee Arthroplasty

BACKGROUND

The SARS-CoV-2 (COVID-19) pandemic caused a massive disruption in elective arthroplasty practice in the United States that to date has not been quantified. We sought to determine the impact of COVID-19 on arthroplasty volumes in the United States, how this varied across the country, and the resultant financial implications.

METHODS

We conducted a retrospective analysis of Medicare fee-for-service beneficiaries undergoing primary and revision total knee arthroplasty (TKA) and total hip arthroplasty (THA) from January 1^st through March 31^st, 2020 with 74,080 TKAs and 54,975 THAs identified. We calculated the percent drop in average daily cases from before and after March 18, 2020. We then examined variation across states in arthroplasty case volumes as it related to reported COVID-19 cases, the impact of COVID-19 on length of stay and percentage of patients discharged home. Finally, we calculated the revenue impact on hospitals and surgeons.

RESULTS

There was a steep decline in TKA and THA volumes in mid-March of 94% and 92%, respectively. There was a significant variation for arthroplasty case volumes across states. We found minimal change in length of stay except for primary THAs with fracture going from 5 + days to 4 days. We saw an increasing trend in discharge to home with the greatest effect in primary THAs with fracture. The total daily hospital Medicare revenue for arthroplasty declined by 87% and surgeon revenue decreased by 85%.

CONCLUSION

The beginning of the COVID-19 pandemic caused a significant decrease in arthroplasty volumes in the Medicare population with a resultant substantial revenue loss for hospitals and surgeons.

Patient Perceptions of COVID-19-Related Surgical Delay: An Analysis of Patients Awaiting Total Hip and Knee Arthroplasty

BACKGROUND

COVID-19 has caused unprecedented delays in elective orthopedic surgery. Understanding patients' perceptions of the disruptions in care and their willingness to reengage the healthcare system are crucial to planning the resumption of elective care.

QUESTIONS/PURPOSES

The purpose of this study was to elicit patient perceptions about delays in total joint arthroplasty during the COVID-19 pandemic.

METHODS

We identified a consecutive series of patients who experienced COVID-19-driven delays to scheduled total hip or knee arthroplasty at an urban, academic medical center in the Southeastern United States. A 20-item survey was administered via telephone. Answers were recorded and descriptive statistics were performed. A post hoc χ-square analysis compared characteristics and outlooks of patients who did and did not immediately desire surgery.

RESULTS

Of 111 patients (64% of those identified) who met inclusion criteria and completed the survey, 96% said they felt that they were treated fairly and 90% said that the surgical delay was in their best interest; 68% reported emotional distress from the delay, but 45% reported a desire to wait longer for the pandemic to subside. Lower joint-function scores, higher pain levels, higher pain catastrophizing scores, and longer latency from personally deciding to pursue surgery were associated with the reported need for immediate surgery.

CONCLUSION

Overall, patients reported that they understood the need for elective surgical delays during the COVID-19 pandemic. However, the psychological implications they reported were not negligible. Patient preference for immediate reengagement with the healthcare system was dichotomous, with many patients favoring precautionarily furthering the delay. Understanding these preferences will help optimize elective orthopedic care during unprecedented times.
