The Impact of the Coronavirus Disease 2019 Pandemic on US Total Knee and Hip Arthroplasty Procedures in 2020. Arthroplast Today 2024; 27:101348. [PMID: 38690096 PMCID: PMC11058713 DOI: 10.1016/j.artd.2024.101348] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/13/2023] [Revised: 01/12/2024] [Accepted: 02/05/2024] [Indexed: 05/02/2024] Open
Abstract
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.

Examining the Relationship Between Value and Patient Satisfaction With Treatment in Total Joint Arthroplasty. Arthroplast Today 2024; 25:101311. [PMID: 38317707 PMCID: PMC10839615 DOI: 10.1016/j.artd.2023.101311] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/04/2023] [Revised: 10/19/2023] [Accepted: 11/26/2023] [Indexed: 02/07/2024] Open
Abstract
Background A shift toward performance, cost, outcomes, and patient satisfaction has occurred with healthcare reform promoting value-based programs. The purpose of this study was to evaluate the relationship between patient satisfaction and value with treatment in a cohort of patients undergoing total knee arthroplasty (TKA) and total hip arthroplasty (THA). Methods Value was determined by the relationship of treatment outcome with episodic cost. Measurements included both clinical outcomes and patient-reported outcomes. Participating surgeons took part in the modified Delphi method resulting in an algorithm measuring patient value. Treatment outcome, cost, and resultant value (outcome/cost) of both TKA and THA were evaluated using binomial logistic regression by adjusting for age, gender, body mass index, Charlson comorbidity index, tobacco, education, and income with patient-reported satisfaction as the outcome. Results This study had a total of 909 patients (TKA n = 438; THA n = 471), with an average age of 67 (TKA) and 65 (THA) years. Patient satisfaction shared a significant positive relationship with treatment outcome for TKA (odds ratio [OR] = 1.53, confidence interval [CI] = 1.35-1.73, P < .001) and THA (OR = 1.93, CI = 1.62-2.29, P < .001). Higher value was associated with a significantly higher odds of patient satisfaction for both TKA (OR = 1.39, CI = 1.25-1.54, P < .001) and THA (OR = 1.70, CI = 1.47-1.97, P < .001). Conclusions This study showed a positive relationship between treatment outcome but not cost with subsequent value and patient satisfaction. This method provides a promising approach to comprehensively evaluate outcomes, cost, and value of total joint arthroplasty procedures. This approach can help predict the probability of value-driven patient satisfaction.

Abstract
ABSTRACT The dynamic health-care environment continues to undergo disruptive change. As the health-care system emerges from the pandemic, underlying issues have progressively become critical. Private equity acquisition is dramatically increasing, and consolidation in the entire health-care system limits choice and access. Challenges in the workforce and supply chain persist, adding pressure on already strained health-care organizations. Innovative solutions are required to provide equitable value-based access to orthopaedic care.

J Arthroplasty 2023; 38:2193-2201. [PMID: 37778918 DOI: 10.1016/j.arth.2023.09.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/10/2023] [Revised: 04/05/2023] [Accepted: 06/14/2023] [Indexed: 10/03/2023] Open
Abstract
OBJECTIVE To develop evidence-based consensus recommendations for the optimal timing of hip and knee arthroplasty to improve patient-important outcomes including, but not limited to, pain, function, infection, hospitalization, and death at 1 year for patients with symptomatic and radiographic moderate-to-severe osteoarthritis or advanced symptomatic osteonecrosis with secondary arthritis of the hip or knee who have previously attempted nonoperative therapy, and for whom nonoperative therapy was ineffective, and who have chosen to undergo elective hip or knee arthroplasty (collectively referred to as TJA). METHODS We developed 13 clinically relevant population, intervention, comparator, outcomes (PICO) questions. After a systematic literature review, the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach was used to rate the quality of evidence (high, moderate, low, or very low), and evidence tables were created. A Voting Panel, including 13 physicians and patients, discussed the PICO questions until consensus was achieved on the direction (for/against) and strength (strong/conditional) of the recommendations. RESULTS The panel conditionally recommended against delaying TJA to pursue additional nonoperative treatment including physical therapy, nonsteroidal antiinflammatory drugs, ambulatory aids, and intraarticular injections. It conditionally recommended delaying TJA for nicotine reduction or cessation. The panel conditionally recommended delay for better glycemic control for patients who have diabetes mellitus, although no specific measure or level was identified. There was consensus that obesity by itself was not a reason for delay, but that weight loss should be strongly encouraged, and the increase in operative risk should be discussed. The panel conditionally recommended against delay in patients who have severe deformity or bone loss, or in patients who have a neuropathic joint. Evidence for all recommendations was graded as low or very low quality. CONCLUSION This guideline provides evidence-based recommendations regarding the optimal timing of TJA in patients who have symptomatic and radiographic moderate-to-severe osteoarthritis or advanced symptomatic osteonecrosis with secondary arthritis for whom nonoperative therapy was ineffective to improve patient-important outcomes, including pain, function, infection, hospitalization, and death at 1 year. We acknowledge that the evidence is of low quality primarily due to indirectness and hope future research will allow for further refinement of the recommendations.

Abstract
BACKGROUND There is ongoing debate regarding the efficacy of arthroscopic partial meniscectomy (APM) for meniscus tears in patients with knee osteoarthritis (OA). Some insurance payers will not authorize APM in patients with knee OA. The purpose of this study was to assess the timing of knee OA diagnoses in patients undergoing APM. METHODS A large commercial national claims data set containing deidentified information from October 2016 to December 2020 was used to identify patients undergoing arthroscopic partial meniscectomy. Data were analyzed to determine whether patients in this group had a diagnosis of knee OA within 12 months before surgery and for the presence of a new diagnosis of knee OA at 3, 6, and 12 months after APM. RESULTS Five lakhs thousand nine hundred twenty-two patients with a mean age of 54.0 ± 8.52 years, with the majority female (52.0%), were included. A total of 197,871 patients underwent APM without a diagnosis of knee OA at the time of the procedure. Of these patients, 109,427 (55.3%) had a previous diagnosis of knee OA within 12 months preceding surgery, and 24,536 (12.4%), 15,596 (7.9%), and 13,301 (6.7%) patients were diagnosed with knee OA at 3, 6, and 12 months after surgery, respectively. CONCLUSION Despite evidence against APM in patients with knee OA, more than half of the patients (55.3%) had a previous diagnosis of OA within 12 months of surgery and 27.0% received a new diagnosis of knee OA within one year of surgery. A notable number of patients had a diagnosis of knee OA either before or shortly after APM.

Abstract
Background There is debate regarding the efficacy of intra-articular (IA) hyaluronic acid (HA) injections for the management of knee osteoarthritis (OA). This study aimed to determine if IA HA utilization and payer coverage of viscosupplementation affected the prevalence of total knee arthroplasty (TKA) procedures and the age of TKA patients. Methods We performed a retrospective analysis from 2014 to 2020 using a large national commercial claims data set. We analyzed the number of TKA procedures and the age of the patients in states that covered IA HA vs those with limited coverage. Mixed random effects and slopes models were used to identify the impact of the IA HA injections. Results Of 7,335,301 patients with knee OA, 440,606 (6.0%) received a TKA procedure at an average age of 59 years. The rate of TKA procedures increased by 0.56% per year (95% confidence interval [CI] 0.46-0.66; P < .001). Payer coverage of IA HA injections had no effect on TKA prevalence (P = .926). The age of surgical patients increased yearly by 0.15 years (95% CI 0.12-0.18; P < .001), regardless of IA HA injections (P = .990). After controlling for demographics and comorbidities, patients that received an IA HA injection had a higher probability of receiving a subsequent TKA (odds ratio = 2.83; 95% CI 2.80-2.87; P < .001); this finding was conditional of patients' age at the first diagnosis of knee OA. Conclusions Additional clinical trials should be employed to identify the role of HA injections in the treatment armamentarium for knee OA.

Making a Joint Decision Regarding the Timing of Surgery for Elective Arthroplasty Surgery After Being Infected With COVID-19: A Systematic Review. J Arthroplasty 2022; 37:2106-2113.e1. [PMID: 35533820 PMCID: PMC9074381 DOI: 10.1016/j.arth.2022.05.006] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/18/2022] [Revised: 04/30/2022] [Accepted: 05/02/2022] [Indexed: 02/02/2023] Open
Abstract
BACKGROUND The Coronavirus Disease 2019 (COVID-19) pandemic has caused a substantial number of patients to have their elective arthroplasty surgeries rescheduled. While it is established that patients with COVID-19 who are undergoing surgery have a significantly higher risk of experiencing postoperative complications and mortality, it is not well-known at what time after testing positive the risk of postoperative complications or mortality returns to normal. METHODS PubMed (MEDLINE), Excerpta Medica dataBASE, and professional society websites were systematically reviewed on March 7, 2022 to identify studies and guidelines on the optimal timeframe to reschedule patients for elective surgery after preoperatively testing positive for COVID-19. Outcomes included postoperative complications such as mortality, pneumonia, acute respiratory distress syndrome, septic shock, and pulmonary embolism. RESULTS A total of 14 studies and professional society guidelines met the inclusion criteria for this systematic review. Patients with asymptomatic COVID-19 should be rescheduled 4-8 weeks after testing positive (as long as they do not develop symptoms in the interim), patients with mild/moderate COVID-19 should be rescheduled 6-8 weeks after testing positive (with complete resolution of symptoms), and patients with severe/critical COVID-19 should be rescheduled at a minimum of 12 weeks after hospital discharge (with complete resolution of symptoms). CONCLUSIONS Given the negative association between preoperative COVID-19 and postoperative complications, patients should have elective arthroplasty surgery rescheduled at differing timeframes based on their symptoms. In addition, a multidisciplinary and patient-centered approach to rescheduling patients is recommended. Further study is needed to examine the impact of novel COVID-19 variants and vaccination on timeframes for rescheduling surgery.

Abstract
➤ In the not-so-distant future, orthopaedic surgeons will be exposed to machines that begin to automatically "read" medical imaging studies using a technology called deep learning. ➤ Deep learning has demonstrated remarkable progress in the analysis of medical imaging across a range of modalities that are commonly used in orthopaedics, including radiographs, computed tomographic scans, and magnetic resonance imaging scans. ➤ There is a growing body of evidence showing clinical utility for deep learning in musculoskeletal radiography, as evidenced by studies that use deep learning to achieve an expert or near-expert level of performance for the identification and localization of fractures on radiographs. ➤ Deep learning is currently in the very early stages of entering the clinical setting, involving validation and proof-of-concept studies for automated medical image interpretation. ➤ The success of deep learning in the analysis of medical imaging has been propelling the field forward so rapidly that now is the time for surgeons to pause and understand how this technology works at a conceptual level, before (not after) the technology ends up in front of us and our patients. That is the purpose of this article.

Do Physicians Overestimate Radiographic Findings in Patients Undergoing Knee Arthroplasty? Arthroplast Today 2022; 15:98-101. [PMID: 35509289 PMCID: PMC9058881 DOI: 10.1016/j.artd.2022.03.022] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/08/2021] [Revised: 03/24/2022] [Accepted: 03/25/2022] [Indexed: 11/24/2022] Open
Abstract
Background Total knee arthroplasty (TKA) is 1 of the top 2 most common and expensive surgical procedures among Medicare beneficiaries. Due to the procedure's high annual cost, overdiagnosis and subsequent overutilization of TKA has substantial health-policy implications. Concerns regarding the overexaggeration of radiographic findings and overutilization of TKA have been expressed by medical insurers. Currently, the standard of care for assessing potential knee arthroplasty candidates includes assigning a Kellgren-Lawrence (KL) radiographic score. Our study investigated the accuracy of reported preoperative KL scores in patients undergoing TKA. Material and methods Records of 277 patients who had underwent TKA at our institution for knee osteoarthritis were randomly selected from a large patient data registry and retrospectively reviewed. Two blinded raters assigned KL scores to the radiographs obtained during the preoperative assessment, which were compared to the scores reported by the operative surgeon. An intraclass correlation coefficient (ICC) was calculated to determine inter-rater reliability. Results Between blinded raters, ICC3k = 0.88 (95% confidence interval: 0.86-0.90, P < .001), demonstrating good reliability. Between all raters, ICC2k = 0.89 (95% confidence interval: 0.86-0.90, P < .001), also demonstrating good agreement. Raters fully agreed on the KL classification for 196 patients (70.76%). Compared with blinded raters, the operative surgeon assigned lower KL scores. Conclusion Reporting of KL score is consistent between operative surgeons and independent reviewers. In cases of disagreement between reviewers, the operative surgeon was generally more conservative in their estimation of the extent of osteoarthritis present radiographically. Concerns regarding inflation of radiographic findings to support surgical preauthorization are unwarranted.

Abstract
BACKGROUND Web-based patient engagement portals are increasing in popularity after total hip and knee arthroplasty (THA and TKA). The literature is mixed regarding patient utilization of these modalities and potential clinical benefit. We sought to determine which demographic factors are associated with increased platform participation and to quantify the impact of a web-based patient portal on patient-reported outcome measures (PROMs). METHODS We performed a retrospective analysis of consecutive primary THA (n = 554) and TKA (n = 485) at a single academic institution with minimum follow-up of 12 months. Patients were divided into those who opted-in and those who opted-out of portal use. Global health and joint-specific PROMs were collected preoperatively and postoperatively. Linear mixed effects modeling, bivariate analysis, and logistic regression were utilized. RESULTS Of the 1039 included patients, 60.6% (336) THA and 62.7% (304) TKA patients enrolled in the portal. Those who opted-in were younger (P < .001, P < .003), had higher body mass index (P = .024, P = .011), and had a higher household income (P < .001, P < .001) in THA and TKA cohorts, respectively. Portal participation in the TKA but not the THA cohort was associated with significant improvement in physical function (P = .017) and joint-specific function (P = .045). For THA patients who opted-in, increased portal logins were associated with more rapid improvement and higher functional scores (P = .013). CONCLUSION There is an inherent difference between patients who opt-in to and those who opt-out of web-based portals. Added resources and support provided by portals may translate to improved PROMs for TKA patients but not THA patients.

[PMID: 34761093 PMCID: PMC8567323 DOI: 10.1016/j.artd.2021.09.009] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/22/2021] [Revised: 09/12/2021] [Accepted: 09/16/2021] [Indexed: 11/26/2022] Open
Abstract
Background Given financial and clinical implications of readmissions after total hip arthroplasty (THA) and the potential for varied expenditures related to a hospital’s teaching status, this study sought to characterize 90-day hospital readmission patterns and assess likelihood of readmission based on teaching designation of a Medicare beneficiaries’ (MB’s) index THA hospital. Methods Retrospective analysis of 2016-2018 Centers for Medicare and Medicaid Services-linked data identified primary THA hospitalizations and readmissions within 90 days. Hospitals were categorized as teaching or nonteaching (Council of Teaching Hospitals and Health Systems). Chi-squared analysis and Fisher exact test assessed differences between readmission hospitals and the index hospital teaching status. Multivariate logistic regression models estimated risk-adjusted probability of experiencing at least one 90-day readmission. Results Analysis identified 433,959 index THA admissions with an all-cause 90-day readmission rate of 9.12%. Most readmissions were to the same hospital regardless of index THA hospital teaching status (67.5% index teaching; 68.2% index nonteaching). Crossover in hospital teaching status from the index procedure to readmission location was more common for those with index THA at a teaching hospital (18.9%) than for MBs with index THA performed at a nonteaching hospital (6.2%). Controlling for patient characteristics, no significant relationship was found between 90-day readmission and index hospital teaching status (odds ratio 0.98, confidence interval 0.947–1.011). Conclusions Overall, while certain patterns of readmission after the index THA were observed, after controlling for patient characters and comorbidities, there was no significant association between 90-day all-cause readmission and index hospital teaching status.

Abstract
The shift to value-based care is changing the practice of medicine. In order to prepare our orthopaedic trainees to survive in a value-based health-care environment, we must expose them to and educate them about value-based programs. This creates both challenges and opportunities for training programs. Academic medical centers (AMCs) will need to carefully consider how to adopt value-based programs and agreements, and assess whether they need alternative facilities, partnerships, or processes in order to be successful. Process improvement principles to adapt physician behavior, the introduction of outcome metrics into the surgical decision-making process, and the development of team-based care can greatly enhance the likelihood of success. AMCs should embrace these challenges to ensure that their residents are well-prepared for the future.

Does Preoperative Opioid Consumption Increase the Risk of Chronic Postoperative Opioid Use After Total Joint Arthroplasty? Arthroplast Today 2021; 10:46-50. [PMID: 34307810 PMCID: PMC8283033 DOI: 10.1016/j.artd.2021.05.012] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/08/2020] [Revised: 04/09/2021] [Accepted: 05/16/2021] [Indexed: 11/24/2022] Open
Abstract
Background Risk-factor identification related to chronic opioid use after surgery may facilitate interventions mitigating postoperative opioid consumption. We evaluated the relationship between opioid use preceding total hip arthroplasty (THA) and total knee arthroplasty (TKA), and chronic use postoperatively, and the risk of chronic opioid use after total joint arthroplasty. Methods All primary THAs and TKAs performed during a 6-month period were identified. Opioid prescription and utilization data (in oxycodone equivalents) were determined via survey and electronic records. Relationship between preoperative opioid use and continued use >90 days after surgery was assessed via Chi-square, with significance set at P < .05. Results A total of 415 patients met inclusion criteria (240 THAs and 175 TKAs). Of the 240 THAs, 199 (82.9%) patients and of the 175 TKAs, 144 (82.3%) patients agreed to participate. Forty-three of 199 (21.6%) THA patients and 22 of 144 (15.3%) TKA patients used opioids within 30 days preoperatively. Nine of 199 (4.5%) THA and 10 of 144 (6.9%) TKA patients had continued use of opioids for >90 days postoperatively. Preoperative opioid consumption was significantly associated with chronic use postoperatively for THA (P = .011) and TKA (P = .024). Five of 43 (11.6%) THA and 4 of 22 (18.2%) TKA patients with preoperative opioid use had continued use for >90 days postoperatively. For opioid naïve patients, 2.6% (4/156) of THA and 4.9% (6/122) of TKA patients had chronic use postoperatively. Conclusions Preoperative opioid use was associated with nearly 5-fold and 4-fold increase in percentage of patients with chronic opioid use after THA and TKA, respectively. Surgeons should counsel patients regarding this risk and consider strategies to eliminate preoperative opioid use.

Perioperative Antibiotic Prophylaxis: Single and 24-Hour Antibiotic Dosages are Equally Effective at Preventing Periprosthetic Joint Infection in Total Joint Arthroplasty. J Arthroplasty 2021; 36:S308-S313. [PMID: 33712358 DOI: 10.1016/j.arth.2021.02.037] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/06/2020] [Revised: 02/08/2021] [Accepted: 02/11/2021] [Indexed: 02/02/2023] Open
Abstract
BACKGROUND Perioperative antibiotic prophylaxis is used to prevent surgical site infection and periprosthetic joint infection (PJI) after total joint arthroplasty (TJA). Secondary to a national shortage of cefazolin, patients at our institution began receiving a single preoperative prophylactic antibiotic dose for primary TJA and no 24-hour postoperative antibiotic prophylaxis. The purpose of the study was to compare the efficacy of single-dose antibiotic use versus 24-hour dosing of prophylactic antibiotics in the prevention of acute PJI and short-term complications after primary TJA. METHODS A retrospective review of 3317 patients undergoing primary TJA performed from January 2015 to December 2019 identified 554 patients who received a single dose of preoperative antibiotic prophylaxis during the antibiotic shortage and 2763 patients who received post-TJA 24-hour antibiotic prophylaxis before the shortage. Patient records were evaluated for acute PJI, superficial infection, 90-day reoperation, and 90-day complications. RESULTS There were no significant differences in patient characteristics between single-dose and 24-hour antibiotic groups. Similarly, there were no significant differences in rates of acute PJI (0.7% vs 0.2%; P = .301), superficial infection (2.4% vs 1.4%; P = .221), 90-day reoperation (2.1% vs 1.1%; P = .155), and 90-day complications (9.9% vs 7.9%; P = .169) between single and 24-hour antibiotic dose. Post hoc power analysis demonstrated adequate sample size, beta = 93%. CONCLUSION Single-dose prophylactic antibiotics did not lead to an increased risk of acute PJI or short-term complications after TJA. Our study suggests that administration of a single antibiotic dose may be safely considered in patients undergoing routine primary TJA.

Abstract
BACKGROUND Patients with mood disorders undergoing total joint arthroplasty (TJA) are at increased risk for poor outcomes. This study seeks to examine the effect of anxiety disorders on pain following TJA and evaluate if anxiety disorders are a modifiable risk factor. METHODS Between March 2019 and July 2020, 319 TJA patients had preoperative anxiety screening using the Generalized Anxiety Disorder 2-item screening tool (GAD-2) and 6-week postoperative Pain Catastrophizing Scale scores. Patients were organized into 4 cohorts based on preoperative selective serotonin reuptake inhibitor/serotonin-norepinephrine reuptake inhibitor (SSRI/SNRI) use and GAD-2 scores: Group 1: no SSRI/SNRI use and GAD-2 score <3 (control patients); Group 2: SSRI/SNRI use and GAD-2 score <3 (appropriately treated GAD patients); Group 3: no SSRI/SNRI use and GAD-2 score ≥3 (untreated GAD patients); and Group 4: SSRI/SNRI use and GAD-2 score ≥3 (poorly treated GAD patients). The cohorts underwent multivariate linear regression analysis and equivalence testing. RESULTS Patients with preoperative GAD-2 scores ≥3 had worse postoperative pain with significantly higher average 6-week postoperative Pain Catastrophizing Scale score than patients with GAD-2 scores <3 (9.90 vs 5.19, P < .001). Patients with appropriately treated GAD and the control group had statistically equivalent postoperative pain, while patients with poorly treated or untreated GAD had worse postoperative pain. CONCLUSION Preoperative GAD is a risk factor for poor postoperative pain control but is a modifiable risk factor when patients are appropriately treated. Screening for preoperative GAD with GAD-2 and referral for treatment may improve patient outcomes and reduce opioid consumption following TJA.

Abstract
INTRODUCTION Traditional physical therapy (PT) requires patients to attend weekly in-office supervised physical therapy appointments. However, between 50% and 70% of patients who would benefit do not receive prescribed PT due to barriers to access. Virtual Reality (VR) provides a platform for remote delivery of PT to address these access barriers. METHODS We developed a VR-PT program consisting of training, games, and a progress dashboard for 3 common lower extremity physical therapy exercises. We enrolled orthopaedic trauma patients with lower extremity injuries. Patients completed a VR-PT session, consisting of training and one of the exercise-based games. Pre- and post-VR-PT questionnaires were completed. RESULTS We enrolled 15 patients with an average age of 51 years. Fourteen patients said they would enroll in a randomized trial in which they had a 50% chance of receiving VR-PT vs receiving standard of care. When asked to rate their experience using the VR-PT module on a scale from 0-10-with 0 being anchored as "I hated it" and 10 being anchored as "I loved it"-the average rating was 7.5. Patients rated the acceptability of VR-PT as a 3.9 out of 5, the feasibility as a 4.0 out of 5, and the usability as a 67.5 out of 100. CONCLUSION The response to VR-PT in this pilot study was positive overall. A VR-based PT program may add value for both patients and clinicians in terms of objective data collection (to aid in compliance monitoring, progression toward goals and exercise safety), increased engagement and increased access.

Abstract
PURPOSE To investigate the functioning of the PROMIS-Global Health (PROMIS-GH) across clinical setting, patient age, and medical complexity by evaluating differential item functioning (DIF) within the Global Physical Health (GPH) and Global Mental Health (GMH) domains. To our knowledge, no study demonstrates lack of differential item functioning (DIF) for PROMIS-GH across these populations. We hypothesize that the PROMIS-GH domains of GMH and GPH will perform similarly when compared across these populations. METHODS Seven thousand nine hundred and seventy four complete PROMIS Global Health measures were retrospectively analyzed using the 'Lordif' package on the R platform. DIF was investigated for both GMH and GPH across clinical environment (Orthopedic Surgery, Family Medicine, & Internal Medicine), age group (≤ 53, > 53-66, > 66), and Charlson Comorbidity Index (CCI:0, CCI:1, CCI:2 +) using quasi Monte Carlo estimation. To assess the significance of DIF, Wald tests were used with the Benjamini & Hochberg procedure. RESULTS No items contained in the GMH or GPH demonstrated DIF across age groups, medical complexity, or clinical environment. CONCLUSION Items assessing the domains of GMH and GPH within the PROMIS-GH function comparably across treatment setting, age category, and medical comorbidities. The PROMIS-Global Health holds potential to facilitate interdisciplinary patient care and patient optimization prior to surgical intervention.

Metric Selection, Metric Targets, and Risk Adjustment Should be Considered in the Design of Gainsharing Models for Bundled Payment Programs in Total Joint Arthroplasty. J Arthroplasty 2021; 36:801-809. [PMID: 33199096 DOI: 10.1016/j.arth.2020.10.007] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/25/2020] [Revised: 10/01/2020] [Accepted: 10/07/2020] [Indexed: 02/02/2023] Open
Abstract
BACKGROUND Under bundled payment models, gainsharing presents an important mechanism to ensure engagement and reward innovation. We hypothesized that metric selection, metric targets, and risk adjustment would impact surgeons' performance in gainsharing models. METHODS Patients undergoing total joint arthroplasty at an urban health system from 2017 to September 2018 were included. Gainsharing metrics included the following: length of stay, % discharge-to-home, 90-day readmission rate, % of patients with episode spend under target price, and % of patients with patient-reported outcomes (PROs) collected. Four scenarios were created to evaluate how metric selection/adjustment impacted surgeons' performance designation: scenario 1 used "aspirational targets" (>60th percentile), scenario 2 used "acceptable targets" (>50th percentile), scenario 3 risk-adjusted surgeon performance prior to comparing aspirational targets, and scenario 4 included a PRO collection metric. Number of metrics achieved determined performance tier, with higher tiers getting a greater share of the gainsharing pool. RESULTS In total, 2776 patients treated by 12 surgeons met inclusion criteria (mean length of stay 3.0 days, readmission rate 4.0%, discharge-to-home 74%, episode spend under target price 85%, PRO collection 56%). Lowering of metric targets (scenario 1 vs. 2) resulted in a 75% increase in the number of high performers and 98% of the gainsharing pool being eligible for distribution. Risk adjustment (scenario 3) caused 50% of providers to move to higher performance tiers and potential payments to increase by 28%. Adding the PRO metric did not change performance. CONCLUSION Quality metric/target selection and risk adjustment profoundly impact surgeons' performance in gainsharing contracts. This impacts how successful these contracts can be in driving innovation and dis-incentivizing the "cherry picking" of patients. LEVEL OF EVIDENCE Level III.

Abstract
BACKGROUND The recent shift toward value-based health care and bundled payments in orthopedic surgery has increased the use patient-reported outcomes (PROs) in standard clinical care. Such assessments of patient function and satisfaction are particularly important among total joint arthroplasty (TJA) patients to monitor postoperative health. PURPOSE The purpose of this study was to assess orthopedic care team perceptions of current and future PRO usage and compare current rates and modes of PRO collection between three urban, academic health care systems. METHODS A literature search was conducted on current PRO uses and barriers to their adoption to generate a 26-question survey. The survey was disseminated to orthopedic surgeons and care team members at three academic health care institutions (institutions A, B, and C). Responses were analyzed for qualitative and quantitative insights. RESULTS Among institutions A, B, and C, PRO collection generally declined from baseline (60%, 90%, 89%) to 6 weeks (67%, 82%, 71%) and 3 months postoperatively (44%, 36%, 47%). However, there were large variations in reported PRO collection intervals among institutions. Respondents reported assessing patient baseline functional status as the most useful current application of PROs and cited the prediction of patient benefit from TJA as the most useful future application for PROs. Though respondents were largely optimistic about PRO utility in clinical care, a small minority remained skeptical. CONCLUSIONS Perceptions of PRO utilization and collection intervals varied considerably among respondents. For PROs to be an accurate and useful clinical tool, standardization and thorough understanding of PRO collection among orthopedic care team members is essential.

Does Productivity-Based Physician Compensation Affect Surgical Rates for Elective Arthroplasty Surgery? J Arthroplasty 2020; 35:3445-3451.e1. [PMID: 32723505 DOI: 10.1016/j.arth.2020.06.066] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/05/2020] [Revised: 06/11/2020] [Accepted: 06/23/2020] [Indexed: 02/02/2023] Open
Abstract
BACKGROUND Surgeon compensation models could potentially influence the utilization of elective procedures. We assessed whether transitioning from salaried to a relative value unit (RVU) productivity-based physician compensation model changed the surgical rate and patient selection in elective total hip and knee arthroplasty (THA and TKA) procedures. METHODS Our institution transitioned from salaried to RVU productivity-based reimbursement in July 2016. We performed a retrospective analysis on patients undergoing primary THA and TKA from July 2014 to July 2018 before and after the transition (salary period n = 820; RVU period n = 1188). Beta regression was used to determine the reimbursement structure as a predictor of surgery. The surgical rate was defined as the number of primary THA and TKA procedures per reimbursement period divided by all arthroplasty and osteoarthritis outpatient clinic encounters. RESULTS There was a surgical rate of 15.8% (95% confidence interval [CI] 13.8%-17.8%) THA and 16.7% (95% CI 15.1%-18.1%) TKA procedures during RVU reimbursement compared to 11.1% (95% CI 9.8%-12.8%) THA and 11.7% (95% CI 10.5%-12.8%) TKA procedures during the salaried period (P < .001). The adjusted odds of undergoing a THA or TKA procedure increased in the RVU compared to the salaried model (THA odds ratio 1.48, 95% CI 1.43-1.53; TKA odds ratio 1.50, 95% CI 1.46-1.55; P < .001). There were no significant differences in patient age, gender, race, body mass index, or Charlson Comorbidity Index in salaried vs RVU productivity periods (P > .05 for all covariates). CONCLUSIONS Productivity-based physician compensation may encourage higher rates of elective arthroplasty procedures without broadening patient selection.

Abstract
BACKGROUND Value-based health-care delivery is a framework for restructuring our health-care systems with the goal of providing better outcomes for patients at lower cost. Value is determined by patient health outcomes per dollar spent on health services. We sought to develop a value dashboard that could be used to easily track and improve the value of total hip and knee arthroplasty (THA and TKA). METHODS We created a value dashboard for TKAs and THAs at our institution. Value was defined as quality of outcomes per dollar spent. The dashboard for each procedure displayed the average value by surgeon, compared with institutional averages for physical function scores and cost. Quality metrics were determined by weighted surgeon ranking using a modified Delphi process and included both clinical and patient-reported outcomes, as measured by the mean change in the Patient-Reported Outcomes Measurement Information System Global-10 (PROMIS-10) physical function score, mean change in the Hip disability and Osteoarthritis Outcome Score-Joint Replacement (HOOS-JR) or the Knee injury and Osteoarthritis Outcome Score-Joint Replacement (KOOS-JR), mean change in the modified Single Assessment Numeric Evaluation (SANE) score, complication rate, periprosthetic joint infection (PJI) rate, and 30-day readmission rate. Average direct costs per surgeon were used. Data from January 2017 through April 2018 were included to ensure 1-year follow-up. RESULTS Six surgeons were included in the value dashboard for TKA, and 5 were included in the THA dashboard. The value for TKA by surgeon ranged from 7% below to 12% above the institutional benchmark. The value for THA by surgeon ranged from 12% below to 7% above the institutional benchmark. CONCLUSIONS The proposed dashboard utilizes value in a health-care framework and could be used for comparing and improving value for THA and TKA. This dashboard successfully combined patient outcome metrics and direct costs of surgical procedures. Future studies should focus on involving patients in this process and using national data to create benchmarks, which could provide a more accurate representation of value than using institutional averages.

Abstract
BACKGROUND While extreme elderly patients (age 80 and above) benefit from joint replacement, there is controversy about whether their physical function improves as much as younger individuals following total hip arthroplasty. METHODS We completed a retrospective cohort study comparing extreme elderly total hip arthroplasty (THA) patients to younger patients. We obtained data from a large institutional repository of 2327 consecutive THAs performed from April 2011 through July 2016 at an American academic medical centre. We performed multivariate regression analyses to determine associations between age group and clinically significant improvement in the Patient-Reported Outcome Measurement Information System (PROMIS)-10 physical component summary (PCS) score. Secondary outcomes included the magnitude of PCS change, length of stay (LOS), and facility discharge. RESULTS There were 187 THAs (8.0%) in patients age ⩾ 80 years compared to 2140 THA procedures in patients < age 80. Extreme elderly patients had similar adjusted odds of achieving clinically significant PCS improvement after THA (p = 0.528) and there were no statistical differences in adjusted postoperative PCS score improvements between the cohorts. Extreme elderly patients were associated with a 0.68 day longer adjusted LOS (p < 0.001) and demonstrated higher adjusted odds of facility discharge following THA (OR 8.96, p < 0.001). CONCLUSIONS Compared to younger patients, extreme elderly individuals had similar adjusted postoperative functional outcomes following THA but utilised substantially more resources in the form of increased time in the hospital and higher rates of facility discharges.

A SANE Approach to Outcome Collection? Comparing the Performance of Single- Versus Multiple-Question Patient-Reported Outcome Measures After Total Hip Arthroplasty. J Arthroplasty 2020; 35:S207-S213. [PMID: 32008770 DOI: 10.1016/j.arth.2020.01.015] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/22/2019] [Revised: 12/18/2019] [Accepted: 01/08/2020] [Indexed: 02/01/2023] Open
Abstract
BACKGROUND Several patient-reported outcome measures (PROMs) exist to measure outcomes after total hip arthroplasty (THA) but can be limited by patient-perceived burden and completion rates. We analyzed whether the modified single assessment numerical evaluation (M-SANE), a one-question PROM, would perform similarly to multiple-question PROMs among patients undergoing primary THA. METHODS Patients undergoing THA completed the Patient-Reported Outcomes Measurement Information System-10 (PROMIS-10), the Hip Disability and Osteoarthritis Outcomes Score Junior (HOOS-Jr), and M-SANE questionnaires both preoperatively and postoperatively. The M-SANE assessment asked patients to assess their hip on a scale from 0 to 10, with 10 being the best possible score. Validity of M-SANE compared with other PROMs was determined by Spearman's correlation and floor and ceiling effects. Responsiveness was analyzed using standardized response mean (SRM). RESULTS One hundred and thirty six patients with at least 1-year follow-up were reviewed. The average M-SANE score improved from 3.3 preoperatively to 7.1 at one year postoperatively. There was moderate to strong correlation at one-year follow-up between the M-SANE and HOOS-Jr (ρ = 0.75, P < .001) and PROMIS-10 physical component summary (ρ = 0.63, P < .001). Floor and ceiling effects of the M-SANE (floor 2.0%, ceiling 21.3%) were comparable to the HOOS-Jr (floor 0.0%, ceiling 20.8%). The responsiveness of the M-SANE after THA (SRM = 1.06, 95% CI: 0.79-1.33) was comparable to HOOS-Jr (SRM = 1.33, 95% CI: 1.08-1.59) and superior to PROMIS-10 physical component summary (SRM = 0.65, 95% CI: 0.55-0.74). CONCLUSION The M-SANE has performed similarly across multiple psychometric properties compared with more burdensome PROMs in assessing longitudinal patient-reported outcomes after THA.

Abstract
BACKGROUND This prospective cohort study evaluates the impact of total hip arthroplasty and total knee arthroplasty on patient's spouses/significant others (SSOs). METHODS Patients and SSOs were provided similar outcome metrics (Global Health Patient-Reported Outcomes Measurement Information System, Hip Disability and Osteoarthritis Outcome Score for Joint Replacement, and Knee Injury and Osteoarthritis Outcome Score for Joint Replacement) at preoperative and postoperative visits. Pearson correlation was used to evaluate scores. RESULTS Our sample included 99 patients (58 total hip arthroplasties and 41 total knee arthroplasties). We found strong correlation between patient and SSO mental status scores. We found moderate correlation for some physical function domains. CONCLUSION SSOs closely share total joint arthroplasty patient's mental and even some of the physical burden of disease and recovery.

Do Medicare's Patient-Reported Outcome Measures Collection Windows Accurately Reflect Academic Clinical Practice? J Arthroplasty 2020; 35:911-917. [PMID: 31889578 DOI: 10.1016/j.arth.2019.11.006] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/29/2019] [Revised: 10/25/2019] [Accepted: 11/06/2019] [Indexed: 02/07/2023] Open
Abstract
BACKGROUND The Comprehensive Care for Joint Replacement (CJR) mandates collection of patient-reported outcome measures (PROMs) for eligible total hip and total knee arthroplasty (THA and TKA) procedures during specific time periods that may not be attainable within routine academic practice. METHODS We performed a retrospective analysis of prospectively collected PROM data from a 2017 cohort of primary THA and TKA patients who completed the Patient-Reported Outcomes Measurement Information System-10 global health survey in preoperative or postoperative time periods. The primary outcome was completion rates of Patient-Reported Outcomes Measurement Information System-10 per the CJR collection periods (90-0 days preoperative and 270-365 days postoperative) compared to an extended postoperative collection period of 270-396 days. Bivariate analysis and logistic regression were used to analyze the association between survey completion rates and patient characteristics. RESULTS Of the 860 primary THAs and TKAs in 2017, 725 (84.3%) had preoperative surveys completed 90-0 days before surgery. Among the 725 patients, 215 (29.7%) completed postoperative surveys within the CJR timeline of 270-365 days. Completion increased by 120 additional surveys (+16.5%) in the additional postoperative time period of 270-396 days (P < .001). No patient or procedural factors significantly correlated with a higher likelihood of postoperative PROM completion (P > .05 for all covariates). CONCLUSION In an academic clinical practice, completion rates of postoperative PROMs as part of routine clinical practice within the CJR mandated period was low for THA and TKA patients. CJR may consider additional time beyond 365 days to improve PROM completion rates.

A One-Question Patient-Reported Outcome Measure Is Comparable to Multiple-Question Measures in Total Knee Arthroplasty Patients. J Arthroplasty 2019; 34:2937-2943. [PMID: 31439407 DOI: 10.1016/j.arth.2019.07.023] [Citation(s) in RCA: 21] [Impact Index Per Article: 4.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/16/2019] [Revised: 07/01/2019] [Accepted: 07/18/2019] [Indexed: 02/01/2023] Open
Abstract
BACKGROUND Patient-reported outcome measures (PROMs) are important for tracking outcomes following total knee arthroplasty (TKA) but can be limited by time constraints and patient compliance. We sought to evaluate the utility of the one-question, modified single assessment numerical evaluation (M-SANE) score in TKA patients compared to legacy PROMs. METHODS Patients undergoing TKA completed the Patient-Reported Outcomes Measurement Information System-10 (PROMIS-10), the Knee Disability and Osteoarthritis Outcomes Score Junior (KOOS Jr), and M-SANE (modified-SANE) assessments both preoperatively and postoperatively. The M-SANE score asked patients to rate their native or prosthetic knee on a scale from 0 to 10, with 10 being the best function. M-SANE validity was determined by the Spearman's correlation between the collected PROMs and the Bland-Altman plots. PROM responsiveness was assessed using the standardized response mean. RESULTS In total, 217 patients completed PROMs preoperatively and at 1 year postoperatively. Floor and ceiling effects of the M-SANE were higher than other PROMs but still relatively low (4%-11%). There was a moderate to strong correlation at nearly all time points between the M-SANE and KOOS Jr (ρ = 0.44-0.78, P < .001). There was a weak correlation between the M-SANE and PROMIS physical component summary at the preoperative evaluation (ρ = 0.28) but a strong correlation at 1-year follow up (0.65, P < .001). The long-term responsiveness of the M-SANE to TKA (standardized response mean [SRM] = 0.98, 95% confidence interval [CI] 0.80-1.17) was comparable to both the KOOS Jr (SRM = 1.19, 95% CI 1.00-1.38) and PROMIS physical component summary (SRM = 0.82, 95% CI 0.74-0.91). Bland-Altman plots demonstrated that the M-SANE and KOOS Jr capture combined knee pain and functionality differently. CONCLUSION The M-SANE score was comparable to validated multiple-question PROMs in TKA patients. The demonstrated validity of the M-SANE, as well as its comparable responsiveness to more lengthy PROMs, highlights its use as a one-question PROM for assessment of patient undergoing TKA.

Defining and Optimizing Value in Total Joint Arthroplasty From the Patient, Payer, and Provider Perspectives. J Arthroplasty 2019; 34:2290-2296.e1. [PMID: 31204223 DOI: 10.1016/j.arth.2019.05.024] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/12/2019] [Revised: 04/29/2019] [Accepted: 05/14/2019] [Indexed: 02/01/2023] Open
Abstract
BACKGROUND The purpose of this study is to define value in bundled total joint arthroplasty (TJA) from the differing perspectives of the patient, payer/employer, and hospital/provider. METHODS Demographic, psychosocial, clinical, financial, and patient-reported outcomes (PROs) data from 2017 to 2018 elective TJA cases at a multihospital academic health system were queried. Value was defined as improvement in PROs (preoperatively to 1 year postoperatively) for patients, improvement in PROs per $1000 of bundle cost for payers, and the normalized sum of improvement in PROs and hospital bundle margin for providers. Bivariate analysis was used to compare high value vs low value (>50th percentile vs <50th percentile). Multivariate analysis was performed to identify predictors. RESULTS A total of 280 patients had PRO data, of which 71 had Medicare claims data. Diabetes (odds ratio [OR], 0.45; P = .02) predicted low value for patients; female gender (OR, 0.25), hypertension (OR, 0.17), pulmonary disease (OR, 0.12), and skilled nursing facility discharge (OR, 0.17) for payers (P ≤ .03 for all); and pulmonary disease (OR, 0.16) and skilled nursing facility discharge (OR, 0.19) for providers (P ≤ .04 for all). CONCLUSION This is the first article to define value in TJA under a bundle payment model from multiple perspectives, providing a foundation for future studies analyzing value-based TJA.

Abstract
INTRODUCTION Periprosthetic hip fractures (PPFX) are serious complications that result in increased morbidity, mortality and healthcare costs. Decreasing hospital readmissions has been a recent healthcare focus, but little is known about the overall costs associated with PPFX or the risk factors associated with readmissions. We investigated patient demographics, treatment types, 30- and 90-day readmission rates, direct costs, and patient risk factors associated with PPFX readmission. METHODS We used the 2013 Nationwide Readmissions Database to select patients who underwent total hip arthroplasty (THA), revision THA, and PPFX treated with open reduction internal fixation (ORIF) or revision THA. Survival analysis was used to evaluate the 90-day all-cause hospital readmission rate, and risk factors were identified using a Cox proportional hazards model, adjusting for patient and hospital characteristics. RESULTS We identified 1269 patients with PPFX treated with ORIF and 3254 treated with revision THA. 90-day readmissions were 20.9% and 27.3%, respectively. Patients with PPFX were older, female, and had multiple medical comorbidities. Patient factors associated with increased risk of readmission include: age; comorbidities; and discharge to skilled nursing facility; Medicare or Medicaid insurance. Hospital factors associated with increased risk of readmission include: large hospitals; nonprofits; metropolitan and teaching hospitals. The cost of readmission for PPFX treated with ORIF was $17,206 and revision THA was $16,504. DISCUSSION Periprosthetic hip fractures have high rates of hospital readmission, implying a significant burden to the healthcare system. Identifying risk factors is an important step towards identifying treatment pathways that can improve outcomes.

Preoperative Weight Loss for Morbidly Obese Patients Undergoing Total Knee Arthroplasty: Determining the Necessary Amount. J Bone Joint Surg Am 2019; 101:1440-1450. [PMID: 31436651 DOI: 10.2106/jbjs.18.01136] [Citation(s) in RCA: 44] [Impact Index Per Article: 8.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 02/01/2023]
Abstract
BACKGROUND Many surgeons require or request weight loss among morbidly obese patients (those with a body mass index [BMI] of ≥40 kg/m) before undergoing total knee arthroplasty. We sought to determine how much weight reduction was necessary to improve operative time, length of stay, discharge to a facility, and physical function improvement. METHODS Using a retrospective review of cohort data that were prospectively collected from 2011 to 2016 at 1 tertiary institution, we identified 203 patients who were morbidly obese at least 90 days before the surgical procedure and had their BMI measured again at the immediate preoperative visit. All heights and weights were clinically measured. We used logistic and linear regression models that adjusted for preoperative age, sex, year of the surgical procedure, bilateral status, physical function (Patient-Reported Outcomes Measurement Information System [PROMIS]-10 physical component score [PCS]), mental function (PROMIS-10 mental component score [MCS]), and the Charlson Comorbidity Index. RESULTS Of the 203 patients in the study, 41% lost at least 5 pounds (2.27 kg) before the surgical procedure, 29% lost at least 10 pounds (4.54 kg), and 14% lost at least 20 pounds (9.07 kg). Among morbidly obese patients, losing 20 pounds before a total knee arthroplasty was associated with lower adjusted odds of discharge to a facility (odds ratio [OR], 0.28 [95% confidence interval (CI), 0.09 to 0.94]; p = 0.039), lower odds of extended length of stay of at least 4 days (OR, 0.24 [95% CI, 0.07 to 0.88]; p = 0.031), and an absolute shorter length of stay (mean difference, -0.87 day [95% CI, -1.39 to -0.36 days]; p = 0.001). There were no differences in operative time or PCS improvement. Losing 5 or 10 pounds was not associated with differences in any outcome. CONCLUSIONS Losing at least 20 pounds before total knee arthroplasty was associated with shorter length of stay and lower odds of facility discharge for morbidly obese patients, even while most patients remained morbidly or severely obese. Although there were no differences in operative time or physical function improvement, this has considerable implications for patient burden and cost reduction. Patients and providers may want to focus on larger preoperative weight loss targets. LEVEL OF EVIDENCE Prognostic Level III.

Identifying regional characteristics influencing variation in the utilization of rotator cuff repair in the United States. J Shoulder Elbow Surg 2019; 28:1568-1577. [PMID: 30956144 PMCID: PMC6646059 DOI: 10.1016/j.jse.2018.12.013] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/07/2018] [Revised: 12/05/2018] [Accepted: 12/11/2018] [Indexed: 02/01/2023]
Abstract
BACKGROUND There is a lack of consensus regarding indications for surgical management of rotator cuff disease, which can lead to increased regional variation. The objectives of this study were to describe the geographic variation in rates of rotator cuff repair (RCR) in the United States over time and to identify regional characteristics associated with utilization. METHODS The United States was divided into 306 hospital referral regions. The adjusted per capita RCR rate was calculated using procedural counts derived from the Medicare Part B Carrier File from 2004-2014. Population-weighted multivariable regression was used to identify regional characteristics independently associated with utilization in 2014. RESULTS In 2014, an 8-fold difference in rates of RCR was found between regions. Between 2010 and 2014, the overall rate of RCR grew only 3.6% and regional variation decreased. Higher regional utilization of several other orthopedic procedures (P < .02), as well as the regional supply of orthopedic surgeons (P = .002), was independently associated with significantly increased utilization. The South, Southeast, and Southwest were independently associated with significantly higher utilization (P < .001) compared with the Northeast. A higher prevalence of resident physicians, a marker of the academic presence within a region, was independently associated with decreased utilization (P < .001). CONCLUSION Utilization of RCR has increased substantially over the past decade, but the rate of growth appears to be slowing. RCR remains a procedure with significant regional variation, and increased utilization across regions is associated with higher orthopedic surgeon supply and increased rates of other orthopedic procedures.

Selecting Residents for Predetermined Factors Identified and Thought to be Important for Work Performance and Satisfaction: A Methodology. JOURNAL OF SURGICAL EDUCATION 2019; 76:949-961. [PMID: 30846348 DOI: 10.1016/j.jsurg.2019.02.004] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/28/2018] [Revised: 12/29/2018] [Accepted: 02/03/2019] [Indexed: 06/09/2023]
Abstract
OBJECTIVE The medical profession seeks to hire and train individuals who consistently meet and/or exceed both job and cultural expectations. Resident selection is often not structured to meet this goal. The objective of this quality improvement project was to evaluate a classic unscripted interview process (OI) in conjunction with a structured, scripted interview process (SI) developed using an established hiring methodology from industry not yet utilized in health care. Qualitative questions we sought to answer: (1) Can SI be practically applied to the selection of residents? (2) Is there a significant difference in the relative position of applicants between the OI and SI rank lists? (3) Qualitatively, does SI help the evaluation/discussion of the affective domain? METHODS Design: Prospective qualitative comparison of OI versus SI. SETTING Dartmouth Hitchcock Medical Center, Lebanon, NH. PARTICIPANTS Applicants were assessed by OI and SI. SI factors were selected based on a job profile. Interview scripts were created from validated behavioral and attitudinal questions. Online assessments assessed 2 important attributes - adaptability and values. Rank lists were compared for relative rank position of applicants. Feedback from faculty was obtained. RESULTS Fifty-two applicants. Critical attributes were self-management, integrator-synthesizer, versatility, communication, and achievement. Absolute mean difference in rank/applicant was 9.8 (standard deviation 8.9, Range 0-36) positions. Comparing the top 20 candidates of each rank list, 40% of those applicants were only on one list. Faculty felt that applicants were given a greater opportunity to show "who they are." CONCLUSIONS In conjunction with OI, an industry proven methodology was practically applied to define and select for high performance for the authors' specific institution. Comparing OI and SI resulted in substantial differences in rank lists. This initiative seemed to provide a structure to evaluate values and motivations that are inherently difficult to assess. Faculty felt SI in conjunction with OI gave a greater chance for applicants to show "who they are."

A comparison of radiographic leg-length and offset discrepancies between 2 intraoperative measurement techniques in anterior total hip arthroplasty. Arthroplast Today 2019; 5:181-186. [PMID: 31286041 PMCID: PMC6588659 DOI: 10.1016/j.artd.2018.09.005] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/22/2018] [Revised: 09/09/2018] [Accepted: 09/11/2018] [Indexed: 01/07/2023] Open
Abstract
BACKGROUND Anterior total hip arthroplasty (THA) allows the use of intraoperative fluoroscopy to assess leg-length and offset discrepancies. Two techniques to accomplish this are the transverse rod method and the radiographic overlay method. The aim of this study was to determine if they are equally effective options for minimizing postoperative radiologic discrepancies. METHODS We completed a retrospective cohort study comparing 106 anterior THAs from 1 surgeon using the transverse rod technique to 94 anterior THAs from another surgeon using the radiograph overlay technique. Radiographic leg-length discrepancy (LLD) and offset discrepancy (OD) were measured independently on postoperative radiographs. Parametric, nonparametric, and categorical statistical tests were used to compare LLD and OD between groups. RESULTS Baseline characteristics were similar between groups. The mean LLD of 4.8 mm in the radiograph overlay group was not significantly different from the 4.4 mm mean discrepancy in the transverse rod group (P = .424), and the rates of LLD < 5 mm and LLD < 10 mm were not significantly different (P = .772, P = .179). The mean OD of 5.1 mm in the radiograph overlay group was not significantly different from the 4.8 mm mean discrepancy in the transverse rod group (P = .668), and there was no significant difference in the rates of OD < 5 mm and OD < 10 mm (P = .488, P = .878). CONCLUSIONS There was no difference between the measured LLD and OD by the 2 surgeons, suggesting that the techniques are equally effective options.

Abstract
BACKGROUND With the advent of bundled payment models, identifying high-performing skilled nursing facilities (SNFs) has become increasingly important. The goal of this study is to develop a rating system to rank SNFs within our health system and to use this system to improve the SNF discharge process at our institution. METHODS All SNF-discharged primary total joint arthroplasty cases in 2017 at a multi-hospital academic health system were queried. Discharge patterns were assessed using heat map analysis. Regression analyses in conjunction with structured discussions with subject matter experts were used to identify measures of SNF efficiency and care quality. A revised rating system was developed and used to identify high-performing facilities within our health system. Opportunities to re-direct patients to higher performing facilities were identified. RESULTS A revised rating system for SNFs was constructed based on risk-adjusted SNF length of stay, 30-day re-admission rate, and 30-day emergency department visit rate. As 82% of patients were discharged to SNFs in close proximity to their home, high-performing SNFs (according to the revised rating system) were identified by geographic region. Mapping of the discharge process revealed multiple opportunities where patients could be re-directed to a higher performing SNF in their area. Using conservative estimates (25% of discharges re-directed), this is expected to achieve a cost saving of $2,600,000 over a 5-year period, mainly through reductions in SNF length of stay. CONCLUSION This study describes the development of a revised rating system for SNFs which, when implemented, is expected to achieve substantial cost savings over a 5-year period.

Abstract
BACKGROUND Newer implants for total knee arthroplasty (TKA) often gain market share at higher cost with little patient-reported and long-term clinical data. We compared outcomes after TKA using two different implants: DePuy PFC Sigma and Attune. METHODS Using a prospective data repository from an academic tertiary medical center, we analyzed 2116 TKAs (1603 Sigma and 513 Attune) from April 2011 through July 2016. Outcomes included length of surgery, length of stay, facility discharge, 90-day reoperation, range of motion (ROM) change, and patient-reported physical function (PCS). RESULTS There was no difference in length of surgery (Attune -2.87 min, P = 0.143). Implant type was not associated with extended LOS (>3 days) (OR 0.80, P = 0.439). There was no difference in facility discharge (OR 0.65, P = 0.103). Unadjusted 90-day reoperations were 0.3% for Sigma and 1.0% for Attune cohorts (P = 0.158). Sigma implants were associated with more ROM improvement in unadjusted analyses (+2.1 degree improvement P = 0.031). Fifty nine percent of the Sigma cohort and 49% of the Attune cohort achieved the minimal clinically important (MCID) change for PCS improvement, although there was no adjusted difference in achieving MCID (Attune OR 0.84, P = 0.435). There was no adjusted difference in absolute PCS improvement (Attune +0.12 score, P = 0.864). CONCLUSIONS Our data show no difference in physical function and most outcomes between Sigma and Attune. Attune implants had shorter absolute LOS, but there were no differences in extended LOS.

Abstract
BACKGROUND With the advent of mandatory bundle payments for total joint arthroplasty (TJA), assessing patients' risk for increased 90-day complications and resource utilization is crucial. This study assesses the degree to which preoperative patient-reported outcomes predict 90-day complications, episode costs, and utilization in TJA patients. METHODS All TJA cases in 2017 at 2 high-volume hospitals were queried. Preoperative HOOS/KOOS JR (Hip Injury and Osteoarthritis Outcome Score/Knee Injury and Osteoarthritis Outcome Score) and Veterans RAND 12-item health survey (VR-12) were administered to patients preoperatively via e-collection platform. For patients enrolled in the Medicare bundle, cost data were extracted from claims. Bivariate and multivariate regression analyses were performed. RESULTS In total, 2108 patients underwent TJA in 2017; 1182 (56%) were missing patient-reported outcome data and were excluded. The final study population included 926 patients, 199 (21%) of which had available cost data. Patients with high bundle costs tended to be older, suffer from vascular disease and anemia, and have higher Charlson scores (P < .05 for all). These patients also had lower baseline VR-12 Physical Component Summary Score (PCS; 24 vs 30, P ≤ .001) and higher rates of extended length of stay, skilled nursing facility discharge, 90-day complications, and 90-day readmission (P ≤ .04 for all). In multivariate analysis, higher baseline VR-12 PCS was protective against extended length of stay, skilled nursing facility discharge, >75th percentile bundle cost, and 90-day bundle cost exceeding target bundle price (P < .01 for all). Baseline VR-12 Mental Component Summary Score and HOOS/KOOS JR were not predictive of complications or bundle cost. CONCLUSION Low baseline VR-12 PCS is predictive of high 90-day bundle costs. Baseline HOOS/KOOS JR scores were not predictive of utilization or cost. Neither VR-12 nor HOOS/KOOS JR was predictive of 90-day readmission or complications.

Are Medicare's Nursing Home Compare Ratings Accurate Predictors of 90-Day Complications, Readmission, and Bundle Cost for Patients Undergoing Primary Total Joint Arthroplasty? J Arthroplasty 2019; 34:613-618. [PMID: 30630648 DOI: 10.1016/j.arth.2018.12.002] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/26/2018] [Revised: 11/09/2018] [Accepted: 12/02/2018] [Indexed: 02/01/2023] Open
Abstract
BACKGROUND Nursing Home Compare (NHC) ratings, created and maintained by Medicare, are used by both hospitals and consumers to aid in the skilled nursing facility (SNF) selection process. To date, no studies have linked NHC ratings to actual episode-based outcomes. The purpose of this study was to evaluate whether NHC ratings are valid predictors of 90-day complications, readmission, and bundle costs for patients discharged to an SNF after primary total joint arthroplasty (TJA). METHODS All SNF-discharged primary TJA cases in 2017 at a multihospital academic health system were queried. Demographic, psychosocial, and clinical variables were manually extracted from the health record. Medicare NHC ratings were then collected for each SNF. For patients in the Medicare bundle, postacute and total bundle cost was extracted from claims. RESULTS Four hundred eighty-eight patients were discharged to a total of 105 unique SNFs. In multivariate analysis, overall NHC rating was not predictive of 90-day readmission/major complications, >75th percentile postacute cost, or 90-day bundle cost exceeding the target price. SNF health inspection and quality measure ratings were also not predictive of 90-day readmission/major complications or bundle performance. A higher SNF staffing rating was independently associated with a decreased odds for >75th percentile 90-day postacute spend (odds ratio, 0.58; P = .01) and a 90-day bundle cost exceeding the target price (odds ratio = 0.69; P = .02) but was similarly not predictive of 90-day readmission/complications. CONCLUSION Results of our study suggest that Medicare's NHC tool is not a useful predictor of 90-day costs, complications, or readmissions for SNFs within our health system.

Abstract
Payors, purchasers, health care providers, and patients are increasingly focused on improving the value-defined as health outcomes that matter to patients per dollar expended-of health care delivered to patients. Orthopaedic providers are in a unique position to pioneer this transition given the introduction of alternative payment models as well as the longitudinal, multidisciplinary, and relatively homogenous nature of high-cost, high-burden orthopaedic conditions (eg, osteoarthritis). First, doing so requires identifying and objectively measuring outcomes that are important to patients (eg, quality of life, pain, functional status) over time. Second, it requires applying value-based principles by reorganizing delivery systems into integrated practice units-a team-based, multidisciplinary model-focused on delivering longitudinal care in a method that is tailored to each patient's values, goals, and disease state. Third, providers must understand the true cost of delivering such care through time-driven activity-based costing approaches. With this knowledge of outcomes and cost, providers and payors/purchasers will be adequately equipped to develop contracts that reward providers for delivering better value (across an orthopaedic patient population) while minimizing risk. The transition to value-based health care is feasible regardless of practice setting.

Patient Outcomes After Total Knee Arthroplasty in Patients Older Than 80 Years. J Arthroplasty 2018; 33:3465-3473. [PMID: 30100133 DOI: 10.1016/j.arth.2018.07.012] [Citation(s) in RCA: 15] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/10/2018] [Revised: 06/27/2018] [Accepted: 07/12/2018] [Indexed: 02/01/2023] Open
Abstract
BACKGROUND Patients aged 80 and above who suffer from end-stage osteoarthritis may benefit from total knee arthroplasty (TKA), but at high potential risk. Additionally, there is controversy about whether functional improvement in patients above age 80 is similar to younger patients. We compared functional improvement, length of stay (LOS), and facility discharge rates after TKA between this cohort and patients less than 80 years of age. METHODS We completed a retrospective cohort study comparing TKA patients aged 80 and above with all patients younger than 80. We utilized data from a prospectively collected institutional repository of 2308 TKAs performed from April 2011 through July 2016 at an academic medical center in the United States. We performed multivariable logistic regression to determine the association between age group and clinically significant improvement in the Patient-Reported Outcome Measurement Information System (PROMIS)-10 physical component summary (PCS) score. Secondary outcomes included the magnitude of PCS change, LOS, and facility discharge. RESULTS There were 175 (7.6%) TKAs in patients older than 80 years compared with 2133 TKAs in patients younger than 80. Patients over 80 had similar adjusted odds of achieving clinically significant PCS improvement following TKA (P = .366), and there was no statistical difference in adjusted postoperative PCS improvement between the 2 age groups. Age 80 and above was associated with a longer adjusted LOS and demonstrated increased odds of facility discharge (odds ratio 4.11, P < .001) after TKA. CONCLUSION Following TKA, patients older than 80 years demonstrate similar adjusted functional improvement in comparison to younger patients. However, older patients did require substantially more resources as they remained in the hospital longer and were discharged to rehabilitation more often.

Abstract
BACKGROUND Tranexamic acid (TXA) is an antifibrinolytic agent commonly used to reduce blood loss in total hip arthroplasty (THA). The purpose of our study was to evaluate the efficacy of TXA in primary THA to support the combined clinical practice guidelines of the American Association of Hip and Knee Surgeons, American Academy of Orthopaedic Surgeons, Hip Society, Knee Society, and American Society of Regional Anesthesia and Pain Medicine on the use of TXA in primary total joint arthroplasty. METHODS A search was performed using Ovid-MEDLINE, Embase, Cochrane Reviews, Scopus, and Web of Science databases to identify all publications before July 2017 on TXA in primary THA. We completed qualitative and quantitative homogeneity testing of all included studies. Direct and indirect comparisons were analyzed using a network meta-analysis followed by consistency testing of the results. RESULTS Two thousand one hundred thirteen publications underwent critical appraisal with 34 publications identified as representing the best available evidence for inclusion in the analysis. Topical, intravenous, and oral TXA formulations provided reduced blood loss and risk of transfusion compared to placebo, but no formulation was clearly superior. Use of repeat doses, higher doses, or variation in timing of administration did not significantly reduce blood loss or risk of transfusion. CONCLUSIONS Strong evidence supports the use of TXA to reduce blood loss and risk of transfusion after primary THA. No specific routes of administration, dosage, dosing regimen, or time of administration provides clearly superior blood-sparing properties.

Laxity Profiles in the Native and Replaced Knee-Application to Robotic-Assisted Gap-Balancing Total Knee Arthroplasty. J Arthroplasty 2018; 33:3043-3048. [PMID: 29909956 DOI: 10.1016/j.arth.2018.05.012] [Citation(s) in RCA: 24] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/20/2018] [Revised: 04/17/2018] [Accepted: 05/07/2018] [Indexed: 02/01/2023] Open
Abstract
BACKGROUND The traditional goal of the gap-balancing method in total knee arthroplasty is to create equal and symmetric knee laxity throughout the arc of flexion. The purpose of this study was to (1) quantify the laxity in the native and the replaced knee throughout the range of flexion in gap-balancing total knee arthroplasty (TKA) and (2) quantify the precision in achieving a targeted gap profile throughout flexion using a robotic-assisted technique with active ligament tensioning. METHODS Robotic-assisted, gap-balancing TKA was performed in 14 cadaver specimens. The proximal tibia was resected, and the native tibiofemoral gaps were measured using a robotic tensioner that dynamically tensioned the soft-tissue envelope throughout the arc of flexion. The femoral implant was then aligned to balance the gaps at 0° and 90° of flexion. The postoperative gaps were then measured during final trialing with the robotic tensioner and compared with the planned gaps. RESULTS The native gaps increased by 3.4 ± 1.7 mm medially and 3.7 ± 2.1 mm laterally from full extension to 20° of flexion (P < .001) and then remained consistent through the remaining arc of flexion. Gap balancing after TKA produced equal gaps at 0° and 90° of flexion, but the gap laxity in midflexion was 2-4 mm greater than at 0° and 90° (P < .001). The root mean square error between the planned gaps and actual measured postoperative gaps was 1.6 mm medially and 1.7 mm laterally throughout the range of motion. CONCLUSION Aiming for equal gaps at 0° and 90° of flexion produced equal gaps in extension and flexion with larger gaps in midflexion. Consistent soft-tissue balance to a planned gap profile could be achieved by using controlled ligament tensioning in robotic-assisted TKA.
