Impact of the Comprehensive Care for Joint Replacement bundled payment model on postoperative utilization of home health and outpatient physical therapy services.

OBJECTIVE: To study the impact of the Comprehensive Care for Joint Replacement (CJR) bundled payment program on postoperative home health and outpatient physical therapy (PT) for total hip or knee arthroplasty (THA/TKA). DESIGN: Retrospective cohort with national Medicare data (5% claims) using a difference-in-differences analysis comparing January 2013-September 2015 (before) versus October 2016-September 2019 (after). SETTING: Administrative claims from hospitals in 34 metropolitan statistical areas with mandatory CJR participation as of 2018 and 42 control metropolitan statistical areas. PARTICIPANTS: Episodes in fee-for-service Medicare beneficiaries (5% claims) undergoing elective THA (n=6,327) or TKA (n=10,764) with community discharge. INTERVENTIONS: Implementation of CJR bundled payment program. MAIN OUTCOME MEASURE(S): Home health and outpatient PT, including any use and number of visits. RESULTS: Program implementation was associated with an increased percentage of THA episodes using home health PT (+8.0 percentage-point change, 95% CI +3.5 to +12.6, P=0.001) but a decreased per-episode number of home health PT visits for THA (-1.1, 95% CI -1.6 to -0.6, P<0.001) and TKA (-1.1, 95% CI -1.4 to -0.07, P<0.001). The program was also associated with an increased per-episode number of outpatient PT visits for TKA in the primary but not sensitivity analyses (+0.8, 95% CI +0.1 to +1.4, P=0.02). CONCLUSIONS: Findings of increased home health PT may reflect an intentional shift in care from the inpatient post-acute setting to the community to decrease costs. Alternatively, the limited impact of CJR, particularly on outpatient PT, could reflect challenges with care coordination in a retrospective bundle spanning multiple care settings.

Systematic review of contemporary interventions for improving discharge support and transitions of care from the patient experience perspective.

AIM: To synthesize the impact of improvement interventions related to care coordination, discharge support and care transitions on patient experience measures. METHOD: Systematic review. Searches were completed in six scientific databases, five specialty journals, and through snowballing. Eligibility included studies published in English (2015-2023) focused on improving care coordination, discharge support, or transitional care assessed by standardized patient experience measures as a primary outcome. Two independent reviewers made eligibility decisions and performed quality appraisals. RESULTS: Of 1240 papers initially screened, 16 were included. Seven studies focused on care coordination activities, including three randomized controlled trials [RCTs]. These studies used enhanced supports such as improvement coaching or tailoring for vulnerable populations within Patient-Centered Medical Homes or other primary care sites. Intervention effectiveness was mixed or neutral relative to standard or models of care or simpler supports (e.g., improvement tool). Eight studies, including three RCTs, focused on enhanced discharge support, including patient education (e.g., teach back) and telephone follow-up; mixed or neutral results on the patient experience were also found and with more substantive risks of bias. One pragmatic trial on a transitional care intervention, using a navigator support, found significant changes only for the subset of uninsured patients and in one patient experience outcome, and had challenges with implementation fidelity. CONCLUSION: Enhanced supports for improving care coordination, discharge education, and post-discharge follow-up had mixed or neutral effectiveness for improving the patient experience with care, compared to standard care or simpler improvement approaches. There is a need to advance the body of evidence on how to improve the patient experience with discharge support and transitional approaches.

Oral Postoperative Antibiotic Prophylaxis for Outpatient Total Hip and Knee Arthroplasty: Describing Current Practices.

BACKGROUND: Despite an increase in outpatient total hip arthroplasty (THA) and total knee arthroplasty (TKA), large-scale data are lacking on current practice for antibiotic prophylaxis prescribing. We aimed to describe current oral antibiotic prophylaxis practices nationally for outpatient THA and TKA. METHODS: This nationwide retrospective cohort study included primary outpatient THA or TKA procedures in patients aged 18 to 64 years from 2018 to 2021 using a national claims database. Oral antibiotic prescriptions filled perioperatively (defined as 5 days before to 3 days after surgery) were extracted; these were categorized and assumed to represent postoperative prophylaxis. Multivariable logistic regression measured associations between patient and surgery characteristics and perioperative oral antibiotic prophylaxis. Adjusted odds ratios (ORs) and 95% confidence intervals (CIs) are reported. RESULTS: Oral antibiotic prescriptions were filled in 16.5% of 73,015 outpatient THA and TKA (18.4% of 24,857 THAs, 15.5% of 48,158 TKAs) procedures. Prescriptions were most often for cephalosporins (74.3%), with cephalexin (52.8%), and cefadroxil (19.1%) being the most common. Non-cephalosporin antibiotics prescribed were mainly clindamycin (6.8%), sulfamethoxazole-trimethoprim (6.7%), and doxycycline (6.2%). The odds of receiving oral antibiotic prophylaxis were higher for THA compared to TKA (OR 1.13, 95% CI 1.09 to 1.18, P < .001) and in the presence of obesity, diabetes, and autoimmune conditions (OR 1.08 to 1.13, P < .001 to .01). Ambulatory surgery center procedures also had significantly increased odds of prophylaxis compared to hospital-based outpatient surgeries (OR 2.62, 95% CI 2.51 to 2.73, P < .001). Additionally, regional and time-based variations were noted. CONCLUSIONS: Perioperative oral antibiotic prophylaxis prescriptions were filled in only 16.5% of outpatient THA and TKA cases, with variation in the type of antibiotic prescribed. The receipt of any prophylaxis and specific medications was associated with demographic, clinical, and procedure-related characteristics. Follow-up research will evaluate associations with infection risk reduction.

Characteristics and Quality of Online Searches for Direct Anterior Versus Posterior Approach for Total Hip Arthroplasty.

BACKGROUND: Online resources are important for patient self-education and reflect public interest. We described commonly asked questions regarding the direct anterior versus posterior approach (DAA, PA) to total hip arthroplasty (THA) and the quality of associated websites. METHODS: We extracted the top 200 questions and websites in Google's "People Also Ask" section for 8 queries on January 8, 2023, and grouped websites and questions into DAA, PA, or comparison. Questions were categorized using Rothwell's classification (fact, policy, value) and THA-relevant subtopics. Websites were evaluated by information source, Journal of the American Medical Association Benchmark Criteria (credibility), DISCERN survey (information quality), and readability. RESULTS: We included 429 question/website combinations (questions: 52.2% DAA, 21.2% PA, 26.6% comparison; websites: 39.0% DAA, 11.0% PA, 9.6% comparison). Per Rothwell's classification, 56.2% of questions were fact, 31.7% value, 10.0% policy, and 2.1% unrelated. The THA-specific question subtopics differed between DAA and PA (P < .001), specifically for recovery timeline (DAA 20.5%, PA 37.4%), indications/management (DAA 13.4%, PA 1.1%), and technical details (DAA 13.8%, PA 5.5%). Information sources differed between DAA (61.7% medical practice/surgeon) and PA websites (44.7% government; P < .001). The median Journal of the American Medical Association Benchmark score was 1 (limited credibility, interquartile range 1 to 2), with the lowest scores for DAA websites (P < .001). The median DISCERN score was 55 ("good" quality, interquartile range 43 to 65), with the highest scores for comparison websites (P < .001). Median Flesch-Kincaid Grade Level scores were 12th grade level for both DAA and PA (P = .94). CONCLUSIONS: Patients' informational interests can guide counseling. Internet searches that explicitly compare THA approaches yielded websites that provide higher-quality information. Providers may also advise patients that physician websites and websites only describing the DAA may have less balanced perspectives, and limited information regarding surgical approaches is available from social media resources.

Surgical treatment of displaced proximal humerus fractures is associated with decreased 1-year mortality in patients aged 65 years and older: a retrospective study of Medicare patients.

BACKGROUND: Proximal humerus fracture (PHF) is a risk factor for 1-year mortality. This study aimed to determine if surgery is associated with lower mortality compared to nonoperative treatment following PHF in older patients. METHODS: This retrospective cohort study used the Medicare Limited Data set. Patients aged 65 years and older with a PHF diagnosis in 2017-2020 were included. Treatment was classified as nonoperative, open reduction internal fixation (ORIF), total shoulder arthroplasty (TSA), or hemiarthroplasty. Multivariable logistic regression models examined (a) predictors of treatment type and (b) the association of treatment type with 1-year mortality, adjusting for patient demographics, comorbidities, frailty, and fracture severity among other variables. A subgroup analysis examined how the relationship between treatment type and 1-year mortality varied based on fracture severity. Adjusted odds ratios (aORs) and 95% confidence intervals (CIs) are reported. RESULTS: In total, 49,072 patients were included (mean age = 76.6 years, 82.3% female). Most were treated nonoperatively (77.5%), 10.9% underwent ORIF, 10.6% underwent TSA, and 1.0% underwent hemiarthroplasty. Examples of factors associated with receipt of operative (versus nonoperative treatment) included worse fracture severity and lower frailty. The 1-year mortality rate after the initial PHF diagnosis was 11.0% for the nonoperative group, 4.0% for ORIF, 5.2% for TSA, and 6.0% for hemiarthroplasty. Compared to nonoperative treatment, ORIF (aOR 0.55; 95% CI [0.47, 0.64]; P < .001) and TSA (aOR 0.59; 95% CI [0.50, 0.68]; P < .001) were associated with decreased odds of 1-year mortality. In the subgroup analysis, ORIF and TSA were associated with a lower 1-year mortality risk for 2-part and 3-/4-part fractures. CONCLUSIONS: Compared to nonoperative treatment, surgery (particularly TSA and ORIF) was associated with a decreased odds of 1-year mortality. This relationship remained significant for 2-part and 3-/4-part fractures after stratifying by fracture severity.

Variation in Utilization of Physical Therapist and Occupational Therapist Services After Rotator Cuff Repair: A Population-Based Study.

OBJECTIVE: The objective of this study was to describe the utilization of physical therapist and occupational therapist services after rotator cuff repair (RCR) and examine variation in rehabilitation characteristics by profession. METHODS: This retrospective cohort study used the IBM MarketScan Commercial Claims and Encounters database. Eligible patients were 18 to 64 years old and had undergone outpatient RCR between 2017 and 2020. Physical therapist and occupational therapist services were identified using evaluation and treatment codes with profession-specific modifiers ("GP" or "GO"). Factors predicting utilization of formal rehabilitation and physical therapist versus occupational therapist services were examined; and univariable and multivariable analyses of days to initiate therapy, number of visits, and episode length by profession were completed. RESULTS: Among 53,497 patients with an RCR, 81.2% initiated formal rehabilitation (93.8% physical therapist, 5.2% occupational therapist, 1.0% both services). Patients in the Northeast and West (vs the South) were less likely to receive rehabilitation (odds ratio [OR] = 0.67 to 0.70) and less likely to receive occupational therapist services (OR = 0.39). Patients living in the Midwest (versus the South) were less likely to receive rehabilitation (OR = 0.79) but more likely to receive occupational therapist services (OR = 1.51). Similarly, those living in a rural (versus urban) area were less likely to utilize rehabilitation (OR = 0.89) but more likely to receive occupational therapist services (OR = 2.21). Additionally, receiving occupational therapist instead of physical therapist services was associated with decreased therapist visits (-16.89%), days to initiate therapy (-13.43%), and episode length (-13.78%). CONCLUSION: Most patients in our commercially insured cohort utilized rehabilitation services, with a small percentage receiving occupational therapist services. We identified profession-specific variation in utilization characteristics that warrants further examination to understand predictors and associated outcomes. IMPACT: Variation in rehabilitation utilization after RCR, including profession-specific and regional differences, may indicate opportunities to improve standardization and quality of care.

Association between timing of initiating supervised physical rehabilitation after rotator cuff repair and incidence of repeat repair and capsulitis: a population-based analysis.

BACKGROUND: There is limited consensus on the optimal time to initiate supervised physical rehabilitation after a rotator cuff repair (RCR). We examined whether timing of initiating supervised physical rehabilitation was associated with repeat RCR or development of adhesive capsulitis within 12 months postoperatively in an observational cohort of commercially insured adults. METHODS: This retrospective cohort study used the IBM MarketScan Commercial Claims and Encounters Database. We included adults aged 18-64 who underwent a unilateral outpatient RCR between 2017 and 2020 and initiated supervised physical rehabilitation 1-90 days postoperatively. Multivariable logistic regression models examined the adjusted association between time of initiating supervised physical rehabilitation (1-13, 14-27, 28-41, and 42-90 days postoperatively) and each of the primary outcomes: repeat RCR and capsulitis. In a sensitivity analysis, time to rehabilitation was alternatively categorized using a data-driven approach of quartiles (1-7, 8-16, 17-30, and 31-90 days postoperatively). We report adjusted odds ratios (OR). RESULTS: Among 33,841 patients (86.7% arthroscopic index RCR), the median time between index RCR and rehabilitation initiation was 16 days (interquartile range 7-30), with 39.9% initiating rehabilitation at 1-13 days. Additionally, 2.2% underwent repeat RCR within 12 months, and 12-month capsulitis was identified in 1.9% of patients. There were no significant associations between timing of initiating rehabilitation and 12-month repeat RCR (OR 0.85-0.93, P = .18-.49) or 12-month capsulitis (OR 0.83-0.94, P = .22-.63). Lack of associations between timing and outcomes was supported in sensitivity analyses. CONCLUSIONS: Timing of initiating rehabilitation was not significantly associated with adverse outcomes after RCR. The finding of no increased odds of repeat RCR or capsulitis with the earliest timing may support earlier initiation of rehabilitation to accelerate return to daily activities. Findings should be replicated in another dataset of similarly-aged patients.

Equitable Integration of Patient-Reported Outcomes Into Clinical Practice-Opportunities, Challenges, and a Roadmap for Implementation.

Patient-reported outcome measures (PROMs) provide a standardized assessment from the patient about their own health status. Although originally developed as research tools, PROMs can be used in clinical care to complement objective functional measures (eg, range of motion) and are increasingly integrated to guide treatment decisions and predict outcomes. In some situations, when PROMs are used during clinical care they can improve patient mortality, outcomes, engagement, well-being, and patient-physician communication. Guidance on how PROMs should be communicated with patients continued to be developed. However, PROM use may have unintended consequences, such as when used implemented without accounting for confounding factors (eg, psychological and social health) or in perpetuating healthcare disparities when used imprecisely (eg, lack of linguistic or cultural validation). In this review, we describe the current state of PROM use in orthopaedic surgery, highlight opportunities and challenges of PROM use in clinical care, and provide a roadmap to support orthopaedic surgery practices in incorporating PROMs into routine care to equitably improve patient health.

Did the Comprehensive Care for Joint Replacement Bundled Payment Program Impact Sex Disparities in Total Hip and Knee Arthroplasties?

BACKGROUND: Sex disparities have been noted across various aspects of total hip/knee arthroplasty (THA/TKA). Given incentives to standardize care, bundled payment initiatives including the Comprehensive Care for Joint Replacement (CJR) program may reduce disparities. This study aimed to assess the CJR program's impact on sex disparities in THA/TKA care and outcomes. METHODS: This retrospective cohort study included 259,673 THAs (61.7% women) and 506,311 TKAs (64.0% women) from a large national database (2013 to 2017). Sex disparities were assessed for care and outcomes related to the period (1) before surgery, (2) during hospitalization for THA/TKA, and (3) after discharge. Disparities were reported as women:men ratios. Difference-in-differences analyses estimated the impact of the CJR program on pre-existing sex disparities. RESULTS: For both THA and TKA, women were less likely than men to present with a Charlson-Deyo comorbidity index >0 (women:men ratio 0.88 to 0.92), but were more likely to require blood transfusions (women:men ratio 1.48 to 1.79) and be discharged to institutional postacute care (women:men ratio 1.50 to 1.66). Difference-in-differences models demonstrated that the CJR bundled payment program reduced sex disparities in institutional postacute care discharges (THA: -2.28%; 95% confidence interval [CI] -4.20 to -0.35%, P = .02; TKA: -2.07%; 95% CI -3.93 to -0.20%; P = .03) and THA 90-day readmissions (-1.00%, 95% CI -1.88 to -0.13%, P = .02), indicating a differential impact of CJR in women versus men for some outcomes. CONCLUSIONS: While sex disparities in THA/TKA persist, the CJR program demonstrates potential to impact such differences. Future research should focus on how potential mechanisms could be leveraged to reduce disparities.

Synthesis of 'joint class' curricula at high volume joint replacement centres and a preliminary model for development and evaluation.

RATIONALE: Preoperative patient education through 'joint class' has potential to improve quality of care for total joint replacement (TJR). However, no formal guidance exists regarding curriculum content, potentially resulting in inter-institutional variation. OBJECTIVE: We aimed to (a) synthesize curriculum components of 'joint classes' across high-volume institutions and (b) develop a preliminary theory of change model for development and evaluation guided by the existing curricula and related literature. METHODS: We reviewed 'joint class' curricula from the websites of the 10 highest-volume TJR centres (by average annual 2017-2019 volume) that publicly disclosed this information. Two reviewers qualitatively compared available content and noted common categories, which were synthesized into key domains across institutions. We then reviewed the PubMed database for literature on pre-TJR patient education and education needs in the past 10 years. Drawing on our curriculum synthesis and related literature, we proposed a theory of change model: hypothesized mechanisms through which 'joint class' confers benefits to patients and health systems. RESULTS: We identified 30 categories in our review of existing class content, which we synthesized into seven key domains: (I) Practical Elements, (II) Logistics, (III) Medical Information, (IV) Modifiable Risk Factors, (V) Expected Outcomes, (VI) Patient Role in Recovery and (VII) Enhanced Education. Variation across institutions was noted. Our preliminary model based on the curriculum synthesis and related literature on the impact of 'joint class' includes three levels: (1) Practical Elements ('joint class' accessibility and information quality), (2) Class Goals (increased health literacy, increased adherence, risk mitigation, realistic expectations, and reduced anxiety) and (3) Target Outcomes (improved clinical outcomes, positive patient experience and increased patient satisfaction). CONCLUSION: Our synthesis identified core common topics included in pre-TJR education but also highlighted variation across institutions, supporting opportunities for standardization. Clinicians and researchers can use our preliminary model to systematically develop and evaluate 'joint classes,' with the goal of establishing a standard of care for TJR preoperative education.

Sleep Disturbance Trends in the Short-Term Postoperative Period for Patients Undergoing Total Joint Arthroplasty.

BACKGROUND: Patients undergoing total joint arthroplasty (TJA) often experience preoperative/postoperative sleep disturbances. Although sleep quality generally improves > 6 months after surgery, patterns of sleep in the short-term postoperative period are poorly understood. This study sought to (1) characterize sleep disturbance patterns over the 3-month postoperative period and (2) investigate clinical and sociodemographic factors associated with 3-month changes in sleep. METHODS: This retrospective analysis of prospectively collected data included 104 primary elective TJA patients. Patients were administered the PROMIS Sleep Disturbance questionnaire preoperatively and at 2 weeks, 6 weeks, and 3 months postoperatively. Median sleep scores were compared between time points using Wilcoxon signed-rank tests, stratified by preoperative sleep impairment. A multivariable logistic regression model identified factors associated with 3-month clinically improved sleep. RESULTS: The percentage of patients reporting sleep within normal limits increased over time: 54.8% preoperatively and 58.0%, 62.5%, and 71.8% at 2 weeks, 6 weeks, and 3 months post-TJA, respectively. Patients with normal preoperative sleep experienced a transient 4.7-point worsening of sleep at 2 weeks ( P = 0.003). For patients with moderate/severe preoperative sleep impairment, sleep significantly improved by 5.4 points at 2 weeks ( P = 0.002), with improvement sustained at 3 months. In multivariable analysis, patients undergoing total hip arthroplasty (versus knee; OR: 3.47, 95% CI: 1.06 to 11.32, P = 0.039) and those with worse preoperative sleep scores (OR: 1.13, 95% CI: 1.04 to 1.23, P = 0.003) were more likely to achieve clinically improved sleep from preoperatively to 3 months postoperatively. DISCUSSION: Patients experience differing patterns in postoperative sleep changes based on preoperative sleep disturbance. Hip arthroplasty patients are also more likely to experience clinically improved sleep by 3 months compared with knee arthroplasty patients. These results may be used to counsel patients on postoperative expectations and identify patients at greater risk of impaired postoperative sleep. STUDY DESIGN: Retrospective analysis of prospectively collected data.

Evaluating a web-based personalized decision report for total knee or hip replacement: Lessons learned from patients.

RATIONALE: Patient-reported outcomes (PROs) are increasingly used in the context of clinical care, but evaluation of patients' perspectives of PRO-based applications in routine care remains limited. AIMS AND OBJECTIVES: This paper investigates patients' acceptability of a personalized web-based decision report for total knee or hip replacement and identifies opportunities to refine the report. METHOD: This qualitative evaluation was embedded in a pragmatic cluster randomized trial of the report. We interviewed 25 patients with knee and hip osteoarthritis about their experiences using the personalized decision report in the context of a surgical consultation. The web-based report contained current descriptive PRO scores of pain, function and general physical health; tailored predicted postoperative PRO scores (i.e., personalized likely outcomes based on actual knee or hip replacement outcomes of similar patients in a national registry); and information about alternative nonoperative treatments. Two trained researchers analysed the interview data qualitatively using a combination of inductive and deductive coding. RESULTS: We identified three major categories for evaluation: content of report, presentation of data in report and engagement with report. Patients generally liked the report overall but specifically valued different pages of the report based on where they were in the surgical decision-making process. Patients identified areas of confusion in data presentation related to graph orientation, terminology and interpretation of T-scores. Patients also highlighted support needs to meaningfully engage with the information in the report. CONCLUSION: Our findings highlight areas of opportunity to further refine this personalized web-based decision report and similar patient-facing PRO applications for routine clinical care. Specific examples include additional tailoring of reports via filterable web-based dashboards and scalable educational supports to facilitate more independent patient understanding and use.

Equity-Driven Implementation of Patient-Reported Outcome Measures in Musculoskeletal Care: Advancing Value for All.

ABSTRACT: The clinical use of patient-reported outcome measures (PROMs) in musculoskeletal care is expanding, encompassing both individual patient management and population-level applications. However, without thoughtful implementation, we risk introducing or exacerbating disparities in care processes or outcomes. We outline examples of opportunities, challenges, and priorities throughout PROM implementation to equitably advance value-based care at both the patient and population level. Balancing standardization with tailored strategies can enable the large-scale implementation of PROMs while optimizing care processes and outcomes for all patients.

Relationships Between Preoperative Mental Health and Improvements in Patient-Reported Outcomes After Total Hip and Knee Arthroplasty.

BACKGROUND: Poor preoperative mental health has been associated with worse outcomes after total hip (THA) and total knee arthroplasty (TKA). To fully understand these relationships, we assessed post-THA and post-TKA improvements in patient-reported mental and joint health by preoperative mental health groups. METHODS: Elective cases (367 THA, 462 TKA) were subgrouped by low (<25th percentile), middle (25th-74th), and high (≥75th) preoperative mental health, using Veterans RAND 12-Item Health Survey Mental Component Summary (MCS) scores. In each subgroup, we assessed the relationship between preoperative MCS and 1-year postoperative change in mental and joint health. Pairwise comparisons and multivariable regression models were applied for THA and TKA separately. RESULTS: Median postoperative mental health change was +14.0 points for the low-MCS THA group, +11.1 low-TKA, +2.0 middle-THA and TKA, -4.0 high-THA, and -4.9 high-TKA (between-group differences P < .001). All MCS groups had improved median joint health scores, without significant between-group differences. Preoperative mental health was negatively associated with mental health improvements in all groups (B = -0.94 - -0.68, P < .001-P = .01) but with improvements in joint health only in the low-THA group (B = -0.74, P = .02). Improvements in mental and joint health were positively associated for low and middle (B = 0.61-0.87, P < .001), but not for high-MCS groups, with this relationship differing for the low versus high group. CONCLUSION: Patients who have low preoperative mental health experienced greater postoperative mental health improvement and similar joint health improvement compared to patients who have high preoperative mental health. Findings can guide subgroup-targeted surgical decision-making and preoperative counseling.
