Pulmonary Rehabilitation Utilization in Older Adults with Chronic Obstructive Pulmonary Disease, 2013-2019.

Rationale: Pulmonary rehabilitation (PR) is very effective in patients with chronic obstructive pulmonary disease (COPD) for improving exercise tolerance and functional capacity, alleviating dyspnea, and improving respiratory quality of life. Access to and use of PR remain poor. Objectives: To assess the trends in PR use and factors associated with PR use in adults with COPD. Methods: We retrospectively analyzed the use of PR in adults with COPD using a 20% Medicare beneficiary population from January 1, 2013, to December 31, 2019. Adults with COPD were identified by 1) two or more outpatient visits >30 days apart within 1 year with an encounter diagnosis of COPD or 2) hospitalization with COPD as the primary diagnosis or a primary diagnosis of acute respiratory failure with a secondary discharge diagnosis of COPD. PR use in each calendar year was identified using Current Procedural Terminology and Healthcare Common Procedure Coding System codes. Factors associated with PR use were tested in bivariate and multivariable logistic regression models. Results: There was a gradual but modest increase in the percentage of patients with COPD using PR; the proportion increased from 2.5% in 2013 to 4.0% in 2019. Overall, the percentage of patients using PR remained low. Factors associated with higher odds of using PR included younger age (66-74 yr), White race, higher socioeconomic status, lower comorbidity score, residence in a metropolitan urban area, and sole or comanagement by a pulmonologist. Conclusions: The use of PR by Medicare beneficiaries with COPD has not changed meaningfully in the past decade and remains low.

Use of a job exposure matrix to predict the risk of work disability in individuals with back pain: An inception cohort study.

Low back pain has a high economic burden in Germany due to back pain-related sick leave, disability pensions, and health care utilization. Work-related factors can predict disabling back pain. Job exposure matrices can be used to consider job demands and occupational characteristics in routine data analysis. This longitudinal analysis tested whether rehabilitation utilization due to musculoskeletal disorders is associated with occupation-linked job exposures in employees with back pain. Data from a German cohort study were used, including employees aged 45 to 59 years with self-reported back pain in the last three months. Individuals' job titles were assessed in the baseline survey in 2017 and matched with parameters of aggregated job exposure indices. Administrative data from the German Pension Insurance were used to extract information on rehabilitation utilization. Proportional hazard models tested the associations. We considered data of 6,569 participants (mean age: 52.3 years; 57.7% women). During follow-up, with a maximum of 21 months, 296 individuals (4.5%) utilized medical rehabilitation due to musculoskeletal disorders. Adjusted analyses showed that high physical (HR = 2.87; 95% CI 1.74; 4.75) and overall (HR = 2.34; 95% CI 1.44; 3.80) job exposures were associated with a higher risk of rehabilitation utilization. Individuals with back pain working in occupations with high physical job exposures have a higher risk for rehabilitation utilization. To prevent work disability in individuals with back pain, occupational groups with high physical job exposures should be actively informed about tailored intervention options.

Physicians' Knowledge of Pulmonary Rehabilitation in China: A Cross-Sectional Study.

To investigate the knowledge of pulmonary rehabilitation (PR) among physicians involved in pulmonary disease management. This multi-regional cross-sectional survey was conducted from December 12, 2019 to January 22, 2020. The participants were enrolled and an electronic questionnaire was exclusively sent to the members of the Lung Cancer Special Committee of the China Medicine Education Association through the WeChat platform. Multivariable logistic regression analysis was performed to explore the associated factors of high PR knowledge scores (≥ 18 points). From the 858 valid questionnaires, the routine implementation of PR was only reported for 16.95% of physicians. The main reason hindering the implementation of PR for patients was the limited knowledge and awareness of PR among the physicians involved (69.1%). A total of 618 and 240 physicians had high and low knowledge scores, respectively. Multivariable analysis suggests that the self-perception of PR knowledge (OR = 1.89, 95% CI: 1.32-2.771, P = 0.001) was independently associated with high knowledge scores, while having no theoretical knowledge of PR was associated with poor knowledge scores (OR = 0.43, 95% CI: 0.26-0.72, P = 0.001). Inadequate knowledge of pulmonary rehabilitation is evident among physicians who are involved in pulmonary disease management in China. This underscores the need for more comprehensive and standardized training to bolster their awareness and effective utilization of pulmonary rehabilitation.

Trends in cardiac rehabilitation rates among patients admitted for acute heart failure in Japan, 2009-2020.

To describe inpatient and outpatient cardiac rehabilitation (CR) utilization patterns over time and by subgroups among patients admitted for acute heart failure (AHF) in Japan. Cardiac rehabilitation (CR) is a crucial secondary prevention strategy for patients with heart failure. While the number of older patients with AHF continues to rise, trends in inpatient and outpatient CR participation following AHF in Japan have not been described to date. We conducted a retrospective cohort study of adult patients hospitalized for AHF in Japan between April 2008 and December 2020. Using data from the Medical Data Vision database, we measured trends in inpatient and outpatient CR participation following AHF. Descriptive analyses and summary statistics for AHF patients by CR participation status were reported. The analytic cohort included 88,052 patients. Among these patients, 37,810 (42.9%) participated in inpatient and/or outpatient CR. Of those, 36,431 (96.4%) participated in inpatient CR only and 1,277 (3.4%) participated in both inpatient and outpatient CR. Rates of inpatient CR rose more than 6-fold over the study period, from 9% in 2009 to 55% in 2020, whereas rates of outpatient CR were consistently low. The rate of inpatient CR participation among AHF patients in Japan rose dramatically over a 12-year period, whereas outpatient CR following AHF was vastly underutilized. Further study is needed to assess the clinical effectiveness of inpatient CR and to create infrastructure and incentives to support and encourage outpatient CR.

Barriers and Facilitators of Center-Based Cardiac Rehabilitation Utilization in South Asian Ethnic Minorities: A META-SYNTHESIS.

The aim of this review was to synthesize literature on the perceptions of South Asian ethnic minorities of the barriers and facilitators to center-based, phase II cardiac rehabilitation (CR). A meta-synthesis approach was used, and findings were reported following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A comprehensive literature search was conducted from database inception dates to July 2022 using the following databases: MEDLINE, EMBASE, APA PsycINFO, Cochrane Database of Systematic Review, CINAHL, Scopus, and Web of Science. The inclusion criteria were studies that examined the barriers and/or facilitators of structured center-based CR among South Asian adult ethnic minorities. Critical appraisal of the included studies was conducted using the Mixed Methods Appraisal Tool. Findings were synthesized using a thematic synthesis approach. Among the 7110 records initially retrieved only nine studies conducted in the United Kingdom or Canada met the inclusion criteria. More barriers than facilitators were studied and reported. Key barriers were the English language difficulty, fatalistic beliefs, previous bad interactions with and negative perception of health care professionals, transportation problems, work schedule conflict, safety issues, and long-distance CR centers. The facilitators included patient-preferred environment, presence of family members during exercise, family and friends support, and encouragement to change lifestyle and enroll in a CR program. The review findings revealed that South Asian ethnic minorities encounter various barriers and facilitators to enroll and complete CR. The findings can inform researchers and clinicians in the development of interventions that are tailored to their cultural needs. The findings can be valuable to health care professionals and policy makers in designing customized CR programs for South Asian minorities.

The utility of inpatient rehabilitation in heart transplantation: A review.

Heart transplantation is considered definitive treatment for patients with end-stage heart failure. Unfortunately, medical and functional complications are common after heart transplantation for a variety of reasons, and these may impact the patients' functional recovery. Rehabilitation is often needed post-operatively to improve functional outcomes. This review article aims to discuss the transplanted heart exercise physiology that may affect the rehabilitation process and provide an overview of the functional benefits of inpatient rehabilitation for cardiac and surgical specialties who may be less familiar with post-acute care rehabilitation options for their patients.

Barriers to cardiac rehabilitation and patient perceptions on the usage of technologies in cardiac rehabilitation: Across-sectional study.

The study aimed to identify factors associated with participation in Phase II cardiac rehabilitation and to assess patient perceptions towards the usage of technologies in cardiac rehabilitation. Despite efforts to promote utilisation of cardiac rehabilitation (CR), participation among patients remains unsatisfactory. Little is known of patient decision to participate Phase II CR in a multi-ethnic country. A cross-sectional study design. A consecutive sampling of 240 patients with coronary heart disease completed Coronary Artery Disease Education Questionnaire (CADE-Q) II, Hospital Anxiety and Depression Scale (HADS), Multidimensional Scale of Perceived Social Support (MSPSS) and Cardiac Rehabilitation Barriers Scale (CRBS). Seventy per cent of patients (mean age 60.5 [SD = 10.6] years, 80.8% male) participated in phase II cardiac rehabilitation. Self-driving to cardiac rehabilitation centres, higher barriers in perceived need/health care and logistical factors were significantly associated with decreased odds of participation. Patients with more barriers from comorbidities/functional status, higher perceived social support from friends, and anxiety were more likely to participate. Chinese and Indians were less likely to participate when compared with Malays. More than 80% of patients used both home and mobile broadband internet, and 72.9% of them would accept the usage of technologies, especially educational videos, instant messenger, and video calls to partially replace the face-to-face, centre-based cardiac rehabilitation approach. Several barriers were associated with non-participation in phase II cardiac rehabilitation. With the high perceived acceptance of technology usage in cardiac rehabilitation, home-based and hybrid cardiac rehabilitation may represent potential solutions to improve participation. By addressing the barriers to cardiac rehabilitation, patients are more likely to be ready to adopt health behaviour changes and adhere to the cardiac rehabilitation programme. The high perceived acceptance of using technologies in cardiac rehabilitation may provide insights into new delivery models that can improve and overcome barriers to participation.

Variation in Utilization of Postoperative Rehabilitation After Total Hip Arthroplasty in Japan

ObjectiveThe use of rehabilitation after arthroplasty in Japan is unknown. We aimed to identify utilization of postoperative rehabilitation after total hip arthroplasty (THA) and to explore the factors associated with rehabilitation usage. DesignA retrospective cohort study using the National Database of Health Insurance Claims and Specific Health Checkups of Japan (NDB). SettingHospitals nationwide. ParticipantsPatients aged >40 years who underwent primary THA between 2017 and 2018 (N=51,332). InterventionsNot applicable. Main Outcome MeasuresThe proportion of patients who underwent postoperative rehabilitation and the number of rehabilitation days were also calculated. Patient demographic characteristics, hospital case volumes, and regions associated with continuing postoperative rehabilitation were analyzed using a Cox proportional hazards model. ResultsEligible patients were selected from 3033 hospitals, of whom 41,192 (80%) were women. Of these, 94% used inpatient rehabilitation, and 20% received outpatient rehabilitation. The mean durations of rehabilitation were 47±72 days for inpatient and 195±109 days for outpatient, respectively. Large-scale hospitals performing more than 200 procedures annually had the shortest duration of inpatient rehabilitation (36-65 days) and the longest duration of outpatient rehabilitation (220-109 days) compared with smaller hospitals. The regression model consistently showed that rehabilitation continued longer at hospitals with over 200 patients per year (HR 0.96, 95% CI 0.93-0.99, P<.007). ConclusionThe Japanese health care system provided higher access to inpatient rehabilitation after THA than other countries. One limitation of this study is that long-term care insurance data were not analyzed. However, outpatient rehabilitation vary according to hospital case volume. Further research is needed to determine the causes of variation in rehabilitation use and the effect of variation on patient outcomes.

Shoulder Muscle Dosimetry and Post-Treatment Rehabilitation Utilization for Early-Stage Breast Cancer Patients

Rehabilitation services for recovery of impaired physical function following breast cancer treatments are largely underutilized. We previously found that breast cancer survivors treated with radiation who received higher radiation doses to the pectoralis major are more likely to self-report shoulder pain and disability. This study aims to address whether radiation dose delivered to the pectoralis major (Pmaj) and pectoralis minor (Pmin) are correlated with referrals for rehabilitation services post-treatment. A retrospective 1:1 matched case-control study was conducted for breast cancer patients who were and were not referred for breast or shoulder rehabilitation services between 2014-2019 at a single academic institution. Patients were included if they had a lumpectomy and adjuvant radiation without regional nodal irradiation. Cohorts were matched based on age, axillary surgery (none vs. sentinel lymph node biopsy (SLNB)), and use of radiation boost. We used non-parametric Mann-Whitney U tests to determine whether Pmaj or Pmin doses (mean, V50Gy, V45Gy, V40Gy, V35Gy, V30Gy, V20Gy) were different between the two groups. Muscle doses were converted to EQD2 assuming an α/β ratio of 2.5. In our study of 30 patients of a median age 57 years (IQR 12.75), 20 (66.67%) patients underwent SLNB in addition to lumpectomy. Median tumor size was 1.1cm (range 0.16 - 7.30cm). Stage was 0 for 11 patients (36.67%), I for 14 patients (46.67%), and II for 5 patients (16.67%). 3D conformal radiation was delivered to the whole breast with a moderately hypofractionated (n = 17) or conventionally fractionated regimen (n = 13). The most common rehabilitation diagnoses were lymphedema (n = 8), scar management (n = 7) and shoulder pain (n = 5). Mean dose to both the Pmaj (20.8Gy vs. 18.6Gy; p = 0.02) and Pmin (30.6Gy vs. 24.6Gy; p = 0.01) were significantly higher in patients who received post-treatment rehabilitation compared to those without. The V40Gy, V35Gy, V30Gy and V20Gy (all p<0.02) for the Pmin and V35Gy, V30Gy and V20Gy for the Pmaj (all p<0.04) were also significantly higher in those who underwent rehabilitation. In this cohort of patients with early-stage breast cancer, increased mean doses to the pectoralis muscles were correlated with increased use of rehabilitation services after radiation. Physicians might consider using these dosimetric data to complement clinical symptoms in the decision-making process for referrals for rehabilitation services. This may help facilitate earlier referral to rehabilitation interventions, which is important since early intervention is correlated with improved shoulder morbidity.

Pectoralis Muscle Dosimetry and Posttreatment Rehabilitation Utilization for Patients With Early-Stage Breast Cancer

Up to 50% of women treated for localized breast cancer will experience some degree of arm or shoulder morbidity. Although radiation is thought to contribute to this morbidity, the mechanism remains unclear. Prior studies have shown biologic and radiographic changes in the pectoralis muscles after radiation. This study thus aimed to investigate the relationship between radiation to the pectoralis muscles and referrals for rehabilitation services posttreatment for arm and shoulder morbidity. A retrospective 1:1 matched case-control study was conducted for patients with breast cancer who were and were not referred for breast or shoulder rehabilitation services between 2014 and 2019 at a single academic institution. Patients were included if they had a lumpectomy and adjuvant radiation. Patients who underwent an axillary lymph node dissection were excluded. Cohorts were matched based on age, axillary surgery, and use of radiation boost. Muscle doses were converted to equivalent dose in 2 Gy fractions assuming an α:β ratio of 2.5 and were compared between the 2 groups. In our cohort of 50 patients of a median age 60 years (interquartile range, 53-68 years), 36 patients (72%) underwent a sentinel lymph node biopsy in addition to a lumpectomy. Although pectoralis muscle doses were generally higher in those receiving rehabilitation services, this was not statistically significant. Pectoralis major V20-40 Gy reached borderline significance, as did pectoralis major mean dose (17.69 vs 20.89 Gy; P=.06). In this limited cohort of patients, we could not definitively conclude a relationship between pectoralis muscle doses and use of rehabilitation services. Given the borderline significant findings, this should be further investigated in a larger cohort.

Nonpharmacological treatment measures, rehabilitation services and membership in patient support groups in axial spondylarthritis (The ATTENTUS axSpA study)

The treatment of axial spondylarthritis (axSpA) includes pharmacological treatment measures (PTM) and nonpharmacological treatment measures (NPTM) as well as supporting resources, such as rehabilitation services (RS) and membership in patient support groups (PSG). Nevertheless, there are significant participation restrictions in patients with axSpA in Germany. Investigation of functional deficits, participation restrictions and utilization of PTM, NPTM, RS and PSG membership in patients with axSpA. Multicentric, observational study of 770 axSpA patients in Germany (ATTENTUS-axSpA). Substantial functional deficits and participation restrictions were observed in axSpA patients. Of the patients 39% did not receive treatment with biological disease-modifying antirheumatic drugs (bDMARD). In the NPTM 54% received physiotherapy less than once per week and 29% once per week. Physical activities were regularly performed by 86% of patients, mainly in the form of home exercises. Training in agym (14%) or sports club (7%) was carried out much less frequently. Of the patients 54% received RS, one third had the last rehabilitation more than 5 years ago and 13% of the patients were members in aPSG. Asignificantly higher utilization of NPTM and rehabilitation was found in this group. Treatment options and resources were often utilized to asmall extent and/or in low intensity by axSpA patients, which could be apossible explanation for persisting restrictions of participation. Membership in aPSG was associated with an increased utilization of NPTM and RS.

A comparison of stiffness of six knee braces with application for posterolateral corner reconstructions.

Posterolateral corner knee injuries are clinically significant, and often require surgical reconstruction. The optimal knee brace following posterolateral corner reconstructions has not yet been determined via clinical nor biomechanical study. We sought to evaluate the stiffness of six types of knee braces to determine the ideal brace type for reducing varus forces, which may have clinical utility for posterolateral corner knee reconstruction rehabilitation. Six different groups of knee braces underwent mechanical testing: cruciate braces, cruciate braces with a valgus bend, medial unloaders, articulating sleeves, hinged braces, and tri-panel immobilizers. Each brace was fitted to the same fiberglass leg model and was secured to the testing apparatus. Force was applied under four-point bending to generate a varus moment about the artificial knee. The stiffness in Newtons per millimeter (N/mm) of each brace was calculated from the slope of the force-displacement curve. The cruciate brace with a valgus bend had the highest average stiffness at 192.61 N/mm (SD 28.53). The articulating sleeve was the least stiff with an average stiffness of 49.86 N/mm (SD 8.99). Stiffness of the cruciate brace was not statistically different compared to cruciate valgus (p = 0.083) or medial unloader (p = 0.098). In this experimental design, a cruciate brace with a valgus bend was shown to have the highest overall stiffness, while an articulating sleeve had the lowest stiffness. Future work will investigate whether this translates into clinical performance.

Patterns of Referral and Postdischarge Utilization of Cardiac Rehabilitation Among Patients Hospitalized With Heart Failure: An Analysis From the GWTG-HF Registry.

Coverage for cardiac rehabilitation (CR) for patients with heart failure with reduced ejection fraction was expanded in 2014, but contemporary referral and participation rates remain unknown. Patients hospitalized for heart failure with reduced ejection fraction (≤35%) in the American Heart Association Get With The Guidelines-Heart Failure registry from 2010 to 2020 were included, and CR referral status was described as yes, no, or not captured. Temporal trends in CR referral were assessed in the overall cohort. Patient and hospital-level predictors of CR referral were assessed using multivariable-adjusted logistic regression models. Additionally, CR referral and proportional utilization of CR within 1-year of referral were evaluated among patients aged >65 years with available Medicare administrative claims data who were clinically stable for 6-weeks postdischarge. Finally, the association of CR referral with the risk of 1-year death and readmission was evaluated using multivariable-adjusted Cox models. Of 69,441 patients with heart failure with reduced ejection fraction who were eligible for CR (median age 67 years; 33% women; 30% Black), 17,076 (24.6%) were referred to CR, and referral rates increased from 8.1% in 2010 to 24.1% in 2020 (Ptrend<0.001). Of 8310 patients with Medicare who remained clinically stable 6-weeks after discharge, the CR referral rate was 25.8%, and utilization of CR among referred patients was 4.1% (mean sessions attended: 6.7). Patients not referred were more likely to be older, of Black race, and with a higher burden of comorbidities. In adjusted analysis, eligible patients with heart failure with reduced ejection fraction who were referred to CR (versus not referred) had a lower risk of 1-year death (hazard ratio, 0.84 [95% CI, 0.70-1.00]; P=0.049) without significant differences in 1-year readmission. CR referral rates have increased from 2010 to 2020. However, only 1 in 4 patients are referred to CR. Among eligible patients who received CR referral, participation was low, with <1 of 20 participating in CR.

Utility of Cardiac Rehabilitation for Long-Term Outcomes in Patients with Hospital-Acquired Functional Decline after Cardiac Surgery: A Retrospective Study.

Hospital-acquired functional decline is an important outcome that affects the long-term prognosis of patients after cardiac surgery. Phase II cardiac rehabilitation (CR) for outpatients is expected to improve prognosis; however, this is not clear in patients with hospital-acquired functional decline after cardiac surgery. Therefore, this study evaluated whether phase II CR improved the long-term prognosis of patients with hospital-acquired functional decline after cardiac surgery. This single-center, retrospective observational study included 2371 patients who required cardiac surgery. Hospital-acquired functional decline occurred in 377 patients (15.9%) after cardiac surgery. The mean follow-up period was 1219 ± 682 days in all patients, and there were 221 (9.3%) cases with major adverse cardiovascular events (MACE) after discharge during the follow-up period. The Kaplan-Meier survival curves indicated that hospital-acquired functional decline and non-phase II CR was associated with a higher incidence of MACE than other groups (log-rank, p < 0.001), additionally exhibiting prognosticating MACE in multivariate Cox regression analysis (HR, 1.59; 95% CI, 1.01-2.50; p = 0.047). Hospital-acquired functional decline after cardiac surgery and non-phase II CR were risk factors for MACE. The participation in phase II CR in patients with hospital-acquired functional decline after cardiac surgery could reduce the risk of MACE.

Regional disparity in the provision of rehabilitation services using the open data from the Japanese national claims database: an ecological study

Utilization and Cost of Outpatient Rehabilitation Services for Pediatric Patients Treated for Acute Lymphoblastic Leukemia Using a Commercial Claims Database

ObjectiveTo investigate the temporal trends and factors associated with outpatient rehabilitation utilization and costs for pediatric acute lymphoblastic leukemia (ALL). DesignDeidentified administrative claims data and longitudinal health information on patients representing a mixture of ages, ethnicities, and geographic regions across the United States were accessed using Optum Labs Data Warehouse. Regression models were constructed to assess associations of outpatient rehabilitation with age, sex, race and ethnicity, year of diagnosis, and region. SettingOutpatient rehabilitation. Participants1000 Patients aged 1-30 years with a new diagnosis of ALL between 1993 and 2017 and continuous insurance coverage (N=1000). InterventionNot applicable. Main Outcome MeasuresOutpatient rehabilitation service utilization and cost based on reimbursed charge codes, summarized over 36 months after cancer diagnosis. ResultsIn 1000 patients, utilization of outpatient rehabilitation services increased from 20% in 1993-2002 to 55% in 2013-2017. In the earliest era examined, physical and/or occupational therapy was provided to 18% and increased to 54% in the latest years. Speech service utilization remained between 5%-8% across timepoints. Inflation-adjusted cost for provision of services did not change significantly across time and remained low, accounting for a median of 1.3% (Q1, Q3 0.3, 3.4) of total treatment cost in 1993-2002 and decreasing to a median 0.4% (Q1, Q3, 0.1, 1.0) in 2013-2017. Age 1 to 5 years at ALL diagnosis was associated with increased rehabilitation visit number and cost, and treatment in the Midwest was associated with increased likelihood of outpatient rehabilitation service utilization compared to other geographic regions. ConclusionsOutpatient rehabilitation services are being increasingly provided to patients with ALL at a relatively low cost per patient, yet geographic variability in care utilization is evident. These services do not add excessively to the overall cost of leukemia care and thus cost containment should not be an excuse to limit access.

Increase in the Initial Outpatient Rehabilitation Utilization for Patients With Total Knee Arthroplasty

The objective of this study was to examine the patient characteristics and features associated with the initial rehabilitation utilization with a particular emphasis on outpatient rehabilitation after total knee arthroplasty (TKA) among 2016-2018 Texas Medicare enrollees. This is a retrospective cohort study. We used chi-square tests to examine the variability in patient demographic and clinical characteristics across the different post-acute rehabilitation settings after TKA. A Cochran-Armitage trend test was used to investigate the yearly trend of outpatient rehabilitation utilization after TKA. Post-acute rehabilitation settings after TKA PARTICIPANTS: The target population was Medicare beneficiaries aged ≥ 65 with an initial TKA in 2016-2018 and complete demographic and residential information (N=44,313). Not applicable. We identified whether patients first used 1) outpatient rehabilitation, 2) home health, 3) self-care, 4) inpatient rehabilitation, 5) skilled nursing, or 6) other setting within the 3 months after TKA. Our results demonstrated an increasing use of the initial outpatient rehabilitation and home health while the use of skilled nursing and inpatient rehabilitation facilities decreased from 2016 to 2018. The increase in outpatient utilization was significant in 2018 compared to 2016 controlling for distance to the TKA facilities, comorbid conditions, sex, race/ethnicity groups (White, Black, Hispanic, and Others), lower income (Medicaid eligible), Medicare entitlement types, age groups, and rurality (OR 1.23, 95% CI 1.12 - 1.34). However, the overall utilization rate of the initial outpatient rehabilitation after TKA remained low, increasing from 7.36% in 2016 to 8.60% in 2018. Despite the growing use of the initial outpatient rehabilitation following TKA, the overall rate of outpatient rehabilitation utilization remained low. Our findings raise an important question as to whether certain patient demographics and clinical groups might have limited access to outpatient rehabilitation after TKA.

Translation, Cross-Cultural Adaptation and Psychometric Validation of the Arabic Version of the Cardiac Rehabilitation Barriers Scale (CRBS-A) with Strategies to Mitigate Barriers.

Cardiac rehabilitation (CR) utilization is low, particularly in Arabic-speaking countries. This study aimed to translate and psychometrically validate the CR Barriers Scale in Arabic (CRBS-A), as well as strategies to mitigate them. The CRBS was translated by two bilingual health professionals independently, followed by back-translation. Next, 19 healthcare providers, followed by 19 patients rated the face and content validity (CV) of the pre-final versions, providing input to improve cross-cultural applicability. Then, 207 patients from Saudi Arabia and Jordan completed the CRBS-A, and factor structure, internal consistency, construct, and criterion validity were assessed. Helpfulness of mitigation strategies was also assessed. For experts, item and scale CV indices were 0.8-1.0 and 0.9, respectively. For patients, item clarity and mitigation helpfulness scores were 4.5 ± 0.1 and 4.3 ± 0.1/5, respectively. Minor edits were made. For the test of structural validity, four factors were extracted: time conflicts/lack of perceived need and excuses; preference to self-manage; logistical problems; and health system issues and comorbidities. Total CRBS-A α was 0.90. Construct validity was supported by a trend for an association of total CRBS with financial insecurity regarding healthcare. Total CRBS-A scores were significantly lower in patients who were referred to CR (2.8 ± 0.6) vs. those who were not (3.6 ± 0.8), confirming criterion validity (p = 0.04). Mitigation strategies were considered very helpful (mean = 4.2 ± 0.8/5). The CRBS-A is reliable and valid. It can support identification of top barriers to CR participation at multiple levels, and then strategies for mitigating them can be implemented.
