Impact of Coronavirus Disease-2019 Protocols on Primary and Revision Total Knee Arthroplasty.

Background: Surgical site infection (SSI) after total knee arthroplasty (TKA) is associated with increased morbidity and healthcare expenditures. During the coronavirus disease-2019 (COVID-19) pandemic, our institution intensified hygiene standards, including greater glove, personal protective equipment (PPE), and mask use. We assessed the effect of these changes on SSI rates in primary total knee arthroplasty (pTKA) and revision total knee arthroplasty (rTKA). Patients and Methods: A retrospective review was performed identifying TKA from January 2019 to June 2021 at a single institution. Baseline characteristics and outcomes were compared before (January 2019 to February 2020) and during (May 2020 to June 2021) the COVID-19 pandemic when no restriction on operative services was in place and were further analyzed during the first (May 2020 to November 2020) and second (December 2020 to June 2021) periods after full operative services were restored. Results: A total of 3,398 pTKA (pre-pandemic: 1,943 [57.2%]; pandemic: 1,455 [42.8%]) and 454 rTKA (pre-pandemic: 229 [50.4%]; pandemic: 225 [49.6%]) were included. For primary cases, superficial and deep SSI rates were similar before and during COVID-19; however, for revision TKA, the incidence of all (-0.32%, p = 0.035) and superficial (-0.32%, p = 0.035) SSIs decreased during COVID-19. Primary TKA had longer operative times (p < 0.001) and shorter length of stay (LOS; p < 0.001) during COVID-19. Both pTKA (p < 0.001) and rTKA (p = 0.003) were discharged to skilled nursing facilities less frequently during COVID-19 as well. Conclusions: After our hospital implemented COVID-19-motivated hygienic protocols, superficial SSI rates decreased in rTKA but not in pTKA. During COVID-19, patients were less likely to be discharged to skilled nursing facilities, and pTKA operative times increased. Although these changes occurred during intensified hygiene protocols, further research is needed to determine how these factors contributed to the observed changes.

RAPT Scores Predict Inpatient Versus Outpatient Status and Readmission Rates After IPO Changes for Total Joint Arthroplasty: An Analysis of 12,348 Cases.

BACKGROUND: Changes to Medicare's Inpatient Only List (IPO) and factors associated with the COVID pandemic have led to more total joint arthroplasty (TJA) patients to be designated as outpatient (OP). This potentially complicates postoperative care for patients with lower functional status and poor social support. These factors make the decision between OP versus inpatient (IP) designation particularly challenging for healthcare teams. The Risk Assessment and Prediction Tool (RAPT) was designed to indicate patient risk for needing posthospital discharge to facility and considers social and functional factors. The purpose of this study is to 1) evaluate the correlation of RAPT as a clinical tool to aid decision-making regarding OP versus IP for Total Hip and Knee Arthroplasty (THA and TKA), 2) assess the impact of recent changes to the IPO and the COVID pandemic on OP TJA readmission rates, and 3) determine whether 90-day readmissions are correlated with RAPT scores after OP TJA. METHODS: We identified all elective TKA and THA patients from 2015 through 2021 in our electronic health record at our large, urban, academic health system. Fracture patients were excluded. For those patients with available RAPT scores, we determined OP and IP designations, with IP defined as those with length-of-stay 2 midnights or more. We performed subanalysis of OP between same-day and next-day discharge. RAPT scores and readmission rates were compared at time points related to changes in the IPO: before TKA removal in 2018 (period A), from 2018 until THA removal in 2020 (Period B), and after January 1, 2020, inclusive of impact from the COVID pandemic (Period C). RESULTS: Reviewed were 11,819 elective TKAs and 10,212 elective THAs. RAPT scores were available for 6,759 TKA patients and 5,589 THA patients. For both TKA and THA, RAPT scores between IP, same-day, and next-day discharged OP were significantly different across all time periods (P < .001). The percentage of OP designation increased across all time periods for TKA and THA. Over these same time periods, mean RAPT scores decreased significantly for both OP TKA and OP THA (P < .01). Concurrent with these changes were significant increases in OP THA 90-day readmission rates across Periods A and B (P = .010) as well as A and C (P = .006). Readmitted OP TKA had significantly lower RAPT scores than OP TKA without readmission during Period B (P < .001). Readmitted OP THA had significantly lower RAPT scores than those without readmission for all periods (P < .05). To facilitate clinical utility, median RAPT scores were also analyzed, and showed that RAPT scores for OP THA patients with readmission were 1 to 2 points lower for all time periods. CONCLUSION: RAPT scores correlate with IP versus OP status for both TKA and THA and vary significantly with same-day versus next-day discharge. OP TJA RAPT scores may also help predict readmission, and counsel some patients away from OP surgery. Average RAPT scores of 10, 9, and 8 appeared to be separators for same day, next day, and inpatient stay. Changes to the IPO and COVID pandemic correlate with decrease in RAPT scores for both TKA and THA patients within all designations. In addition, a shift toward lower RAPT for OP TJA correlates with increased 90-day readmission rates for OP TJA. Taken together, these results suggest that patients with poorer function and worse social support systems are increasingly being driven toward OP surgery by these changes, which may play a role in increasing readmission rates. Social support and functional factors should be considered for OP elective TKA and THA. Further, any OP TJA value-based payment system must account for these variables.

Impact of COVID-19 Protocols on Primary and Revision Total Hip Arthroplasty.

BACKGROUND: Surgical site infection (SSI) after total hip arthroplasty (THA) is associated with increased morbidity, mortality, and healthcare expenditures. Our institution intensified hygiene standards during the COVID-19 pandemic; hospital staff exercised greater hand hygiene, glove use, and mask compliance. We examined the effect of these factors on SSI rates for primary THA (pTHA) and revision THA (rTHA). METHODS: A retrospective review was performed identifying THA from January 2019 to June 2021 at a single institution. Baseline characteristics and outcomes were compared before (January 2019 to February 2020) and during (May 2020 to June 2021) the COVID-19 pandemic and during the first (May 2020 to November 2020) and second (December 2020 to June 2021) periods of the pandemic. Cohorts were compared using the Chi-squared test and independent samples t-test. RESULTS: A total of 2,682 pTHA (prepandemic: 1,549 [57.8%]; pandemic: 1,133 [42.2%]) and 402 rTHA (prepandemic: 216 [53.7%]; Pandemic: 186 [46.2%]) were included. For primary and revision cases, superficial and deep SSI rates were similar before and during COVID-19. During COVID-19, the incidence of all (-0.43%, P = .029) and deep (-0.36%, P = .049) SSIs decreased between the first and second periods for rTHA. pTHA patients had longer operative times (P < .001) and shorter length of stay (P = .006) during COVID-19. Revision cases had longer operative times (P = .004) and length of stay (P = .046). Both pTHA and rTHA were discharged to skilled nursing facilities less frequently during COVID-19. CONCLUSION: During COVID-19, operative times were longer in both pTHA and rTHA and patients were less likely to be discharged to a skilled nursing facility. Although intensified hygienic standards may lower SSI rates, infection rates did not significantly differ after our hospital implemented personal protective guidelines and a mask mandate.

American Association of Hip and Knee Surgeons Advocacy Efforts in Response to the SARS-CoV-2 Pandemic.

As soon as it became clear that our economy was going to be paralyzed by the SARS-CoV-2 pandemic, the American Association of Hip and Knee Surgeons leadership acted swiftly to ensure that our members were going to be eligible for the anticipated federal economic stimulus. The cessation of elective surgery, enacted in mid-March and necessary to stop the spread of the SARS-CoV-2 virus, would surely challenge the solvency of many of our members' practices. Although our advocacy efforts discussed further have helped, clearly more relief is needed. Fortunately, our mitigation efforts have led to a "flattening of the curve" and discussions have begun on when, where, and how to safely start elective surgery again.

The Ethics of Telemedicine

Improvement in telecommunication technology, the widespread access to this technology across all socioeconomic categories, and the need to leverage health care provider access has resulted in telemedicine's rapid growth.1'3 This is particularly true for orthopedic surgery. [...]telemedicine will play an increasingly important role in our profession. The purpose of this report is to examine these issues using the ethical and legal principles of beneficence, nonmaleficence, justice, and primacy of patient interest in order to gain a better understanding of how telemedicine can be used to provide care within the ethical and legal boundaries of medicine. Mill opined that individual rights to happiness may be limited when it is for the good of society.5 Clearly, allowing patients unfettered access to providers when doing so would endanger those providers and other patients, would harm society. [...]we are well within ethical bounds to insist that patients who pose a risk to others by horizontal disease transmission seek routine medical care via telemedicine.

Ethical Implications of Resuming Elective Orthopedic Surgery During the COVID-19 Pandemic.

The COVID-19 pandemic has had unprecedented impact on the United States health care system. One of the consider-ations was the decision to halt elective orthopedic surgery to preserve consumption of scarce resources. However, as the number of COVID-19 cases decrease, there will be discus-sions regarding the modality of resuming elective orthopedic surgery. Ethical considerations will come to the forefront in terms of determining the best course of action, patient selection, resource rationing, and financial implications. These factors will be examined through the lens of the four tenets of bioethics, beneficence, maleficence, autonomy, and justice, to elucidate the best approach in ethically manag-ing elective orthopedic surgery during a global pandemic.

Patient and Surgeon Satisfaction with Telehealth During the COVID-19 Pandemic.

BACKGROUND: Until recently, telehealth represented a small fraction of orthopedic surgery patient interactions. The COVID-19 pandemic necessitated a swift adoption of telehealth to avoid patient and provider exposure. This study analyzed patient and surgeon satisfaction with telehealth within the department of orthopedic surgery during the height of the COVID-19 pandemic. METHODS: All orthopedic surgery patients who partici-pated in telehealth from March 30 to April 30, 2020, were sent a 14-question survey via e-mail. Orthopedic surgeons who used telehealth were sent a separate 14-question survey at the end of the study period. Factors influencing patient satisfaction were determined using univariate proportional odds and multivariate partial proportional odds models. RESULTS: Three hundred and eighty-two patients and 33 surgeons completed the surveys. On average, patients were "satisfied" with telehealth (4.25/5.00 ± 0.96), and 37.0% preferred future visits to be conducted using telehealth. Multivariate partial proportional odds modeling determined that patients who found it easiest to arrange the telehealth visit had greater satisfaction (5.00/5.00 vs. 1.00-3.00/5.00: OR = 3.058; 95% CI = 1.621 to 5.768, p < 0.001), as did patients who believed they were able to communicate most effectively (5.00/5.00 vs. 1.00-4.00/5.00: OR = 20.268; 95% CI = 5.033 to 81.631, p < 0.001). Surgeons were similarly "satisfied" with telehealth (3.94/5.00 ± 0.86), and while their physical examinations were only "moderately effec-tive" (2.64/5.00 ± 0.99), they were "fairly confident" in their diagnoses (4.03/5.00 ± 0.64). Lastly, 36.7% ± 24.7% of surgeons believed that their telehealth patients required an in-person visit, and 93.9% of surgeons will continue using telehealth in the future. CONCLUSIONS: Telehealth emerged as a valuable tool for the delivery of health care during the COVID-19 pandemic. While both patients and surgeons were satisfied with its use, this study identifies areas that can improve the patient and surgeon experience. The effectiveness and satisfaction with telehealth should inform regulatory and reimbursement policy.

The Use and Acceptance of Telemedicine in Orthopedic Surgery During the COVID-19 Pandemic.

Background:A major byproduct of the recent coronavirus disease 2019 (COVID-19) pandemic has been the accelerated adoption of telemedicine within orthopedic practices.Introduction:The purpose of the study is to evaluate satisfaction associated with telemedicine and to determine how telemedicine is used by orthopedic surgeons in response to social distancing efforts necessitated by the COVID-19 pandemic.Methods:We developed a survey to evaluate surgeon's perception of telemedicine during the COVID-19 pandemic. The survey consisted of four major sections focusing on (1) surgeon characteristics and current use of telemedicine, (2) telemedicine for new patients, (3) telemedicine for routine follow-up patients, and (4) telemedicine for postoperative patients.Results:We collected 268 survey responses. Overall, 84.8% of surgeons were using telemedicine, but only 20.5% of surgeons were using it before the COVID-19 pandemic. The overall satisfaction with telemedicine was 70.3% ± 20.9%. Of those who use telemedicine, 75% currently use it for new patients, 86.6% currently use it for routine follow-up patients, and 80.8% currently use it for postoperative patients (p = 0.01). Surgeons had higher satisfaction with building rapport and performing physical examination maneuvers for either routine follow-up or postoperative patients than for new patients (p < 0.0001 for both). However, satisfaction with obtaining imaging did not differ among the cohorts (p = 0.36). Surgeons felt they are more likely to continue to use telemedicine after the COVID-19 pandemic for either routine follow-up or postoperative patients than for new patients (p < 0.0001).Discussion:Owing to challenges posed by the COVID-19 pandemic, telemedicine use has increased substantially among orthopedic surgeons in recent months.Conclusions:Our study established that physician implementation of telemedicine has increased significantly as a result of the COVID-19 pandemic, with the majority of surgeons satisfied with its use in their practice, and plan on incorporating telemedicine in their practices beyond the pandemic.

Modification of a Validated Risk Stratification Tool to Characterize Geriatric Hip Fracture Outcomes and Optimize Care in a Post-COVID-19 World.

OBJECTIVES: (1) To demonstrate how a risk assessment tool modified to account for the COVID-19 virus during the current global pandemic is able to provide risk assessment for low-energy geriatric hip fracture patients. (2) To provide a treatment algorithm for care of COVID-19 positive/suspected hip fractures patients that accounts for their increased risk of morbidity and mortality. SETTING: One academic medical center including 4 Level 1 trauma centers, 1 university-based tertiary care referral hospital, and 1 orthopaedic specialty hospital. PATIENTS/PARTICIPANTS: One thousand two hundred seventy-eight patients treated for hip fractures between October 2014 and April 2020, including 136 patients treated during the COVID-19 pandemic between February 1, 2020 and April 15, 2020. INTERVENTION: The Score for Trauma Triage in the Geriatric and Middle-Aged ORIGINAL (STTGMAORIGINAL) score was modified by adding COVID-19 virus as a risk factor for mortality to create the STTGMACOVID score. Patients were stratified into quartiles to demonstrate differences in risk distribution between the scores. MAIN OUTCOME MEASUREMENTS: Inpatient and 30-day mortality, major, and minor complications. RESULTS: Both STTGMA score and COVID-19 positive/suspected status are independent predictors of inpatient mortality, confirming their use in risk assessment models for geriatric hip fracture patients. Compared with STTGMAORIGINAL, where COVID-19 patients are haphazardly distributed among the risk groups and COVID-19 inpatient and 30 days mortalities comprise 50% deaths in the minimal-risk and low-risk cohorts, the STTGMACOVID tool is able to triage 100% of COVID-19 patients and 100% of COVID-19 inpatient and 30 days mortalities into the highest risk quartile, where it was demonstrated that these patients have a 55% rate of pneumonia, a 35% rate of acute respiratory distress syndrome, a 22% rate of inpatient mortality, and a 35% rate of 30 days mortality. COVID-19 patients who are symptomatic on presentation to the emergency department and undergo surgical fixation have a 30% inpatient mortality rate compared with 12.5% for patients who are initially asymptomatic but later develop symptoms. CONCLUSION: The STTGMA tool can be modified for specific disease processes, in this case to account for the COVID-19 virus and provide a robust risk stratification tool that accounts for a heretofore unknown risk factor. COVID-19 positive/suspected status portends a poor outcome in this susceptible trauma population and should be included in risk assessment models. These patients should be considered a high risk for perioperative morbidity and mortality. Patients with COVID-19 symptoms on presentation should have surgery deferred until symptoms improve or resolve and should be reassessed for surgical treatment versus definitive nonoperative treatment with palliative care and/or hospice care. LEVEL OF EVIDENCE: Prognostic Level III. See Instructions for Authors for a complete description of Levels of Evidence.

Increased Mortality and Major Complications in Hip Fracture Care During the COVID-19 Pandemic: A New York City Perspective.

OBJECTIVES: To examine one health system's response to the essential care of its hip fracture population during the COVID-19 pandemic and report on its effect on patient outcomes. DESIGN: Prospective cohort study. SETTING: Seven musculoskeletal care centers within New York City and Long Island. PATIENTS/PARTICIPANTS: One hundred thirty-eight recent and 115 historical hip fracture patients. INTERVENTION: Patients with hip fractures occurring between February 1, 2020, and April 15, 2020, or between February 1, 2019, and April 15, 2019, were prospectively enrolled in an orthopaedic trauma registry and chart reviewed for demographic and hospital quality measures. Patients with recent hip fractures were identified as COVID positive (C+), COVID suspected (Cs), or COVID negative (C-). MAIN OUTCOME MEASUREMENTS: Hospital quality measures, inpatient complications, and mortality rates. RESULTS: Seventeen (12.2%) patients were confirmed C+ by testing, and another 14 (10.1%) were suspected (Cs) of having had the virus but were never tested. The C+ cohort, when compared with Cs and C- cohorts, had an increased mortality rate (35.3% vs. 7.1% vs. 0.9%), increased length of hospital stay, a greater major complication rate, and a greater incidence of ventilator need postoperatively. CONCLUSIONS: COVID-19 had a devastating effect on the care of patients with hip fracture during the pandemic. Although practice patterns generally remained unchanged, treating physicians need to understand the increased morbidity and mortality in patients with hip fracture complicated by COVID-19. LEVEL OF EVIDENCE: Prognostic Level III. See Instructions for Authors for a complete description of Levels of Evidence.

The Response of an Orthopedic Department and Specialty Hospital at the Epicenter of a Pandemic: The NYU Langone Health Experience.

As the world grapples with the COVID-19 pandemic, we as health care professionals thrive to continue to help our patients, and as orthopedic surgeons, this goal is ever more challenging. As part of a major academic tertiary medical center in New York City, the orthopedic department at New York University (NYU) Langone Health has evolved and adapted to meet the challenges of the COVID pandemic. In our report, we will detail the different aspects and actions taken by NYU Langone Health as well as NYU Langone Orthopedic Hospital and the orthopedic department in particular. Among the steps taken, the department has reconfigured its staff's assignments to help both with the institution's efforts and our patients' needs from reassigning operating room nurses to medical COVID floors to having attending surgeons cover urgent care locations. We have reorganized our residency and fellowship rotations and assignments as well as adapting our educational programs to online learning. While constantly evolving to meet the institution's and our patient demands, our leadership starts planning for the return to a new "normal".
