Home-Health-Care Physical Therapy Improves Early Functional Recovery of Medicare Beneficiaries After Total Knee Arthroplasty

Home health utilization in the Veterans Health Administration: Are there rural and urban differences?

PURPOSE

Growing numbers of older adults need home health care, yhese services may be more difficult to access for rural Veterans, who represent one-third of Veterans Health Administration (VA) enrollees. Our objective was to examine whether home health use differs within VA based on rurality.

METHODS

We examined national VA administrative data for 2019-2021 (January 1, 2019 to December 31, 2021) among Veterans ages ≥65 years. Using descriptive and multivariable analyses, we assessed whether rural versus urban Veterans differed in (1) the likelihood of using any home health and (2) for those who received ≥1 visit, number of visits received.

RESULTS

Among home health users (n = 107,229, 33.1% rural), rural and urban Veterans were similar in age (77.0 vs. 77.2 years). Rural Veterans were less likely to be highly frail (38.9% rural vs. 40.4% urban) or diagnosed with dementia (13.5% vs. 17.6%). After adjusting for Veterans' characteristics, rural Veterans were more likely to receive any home health (odds ratio: 1.10; 95% confidence interval [CI]: 1.07, 1.13). Among Veterans who received ≥1 home health visit, rurality was associated with considerably fewer expected visits (incident rate ratio: 0.70; 95% CI: 0.68, 0.72).

CONCLUSIONS

Although rural Veterans were more likely than urban Veterans to receive any home health services, they received considerably fewer home health visits. This difference may represent an access issue for rural Veterans. Future research is needed to identify reasons for these differences and develop strategies to ensure rural Veterans' care needs are equitability addressed.

Help or Hurt? The Impact of Digital Finance on the Physical Health of the Elderly in China

Under the backdrop of global aging, the escalating number of elderly individuals in poor health poses a growing social burden and impacts economic development and social stability. A fundamental question arises as to whether the advancements of digital finance (DF) can effectively enhance the physical health of the elderly. This study aims to investigate the impact of DF on the physical health of the elderly by utilizing data from the China Health and Retirement Longitudinal Study (CHARLS) conducted in 2013, 2015, and 2018. The results reveal a significant positive impact of DF on enhancing the physical health of the elderly. Furthermore, the study demonstrates that this impact is particularly pronounced among the elderly with higher educational attainment, stronger intergenerational links, and those residing in central cities. A mechanism analysis further reveals that DF contributes to improving the physical health of the elderly by augmenting household disposable income, alleviating liquidity constraints, and enhancing the utilization of medical services. These findings offer valuable insights for the future development of DF and the implementation of policies promoting healthy aging and active aging.

Telerehabilitation following fast-track total knee arthroplasty is effective and safe: a randomized controlled trial with the ReHub® platform

PURPOSE

After a total knee arthroplasty (TKA), ensuring rehabilitation is continued at home is essential for a successful recovery. The aim of this randomized clinical trial (NCT04155957) was to demonstrate the safety and efficacy of an interactive telerehabilitation system (ReHub®) to guide and provide feedback during exercise in the postoperative period of a fast-track TKA program.

METHODS

Fifty-two patients who underwent TKA were randomized to intervention (N = 26) or control (N = 26). Upon discharge, they followed a 4-week plan of 5 daily exercises and up to 10 physiotherapy home visits. The intervention group performed exercises with ReHub® autonomously, control did not use any auxiliary device. Data were collected 1) on the day of discharge, 2) after 2 weeks and 3) after 4 weeks.

RESULTS

Telerehabilitation patients showed higher adherence to exercise (p = 0.002) and greater quadriceps strength (p = 0.028). No significant differences between groups were found in other outcomes. Only 1 adverse event was linked to ReHub®. Patients gave the platform high System Usability Scale scores (83/100).

CONCLUSION

Interactive telerehabilitation with ReHub® during a post-TKA exercise program is effective, safe, and well-received by patients. It provides real-time performance feedback and ensures communication. Quadriceps strength and adherence to the exercise plan are improved with ReHub®.

Variation in Home Healthcare Use by Dementia Status Among a National Cohort of Older Adults

BACKGROUND

Medicare-funded home healthcare (HHC) delivers skilled nursing, therapy, and related services through visits to the patient's home. Nearly one-third (31%) of HHC patients have diagnosed dementia, but little is currently known regarding how HHC utilization and care delivery differ for persons living with dementia (PLwD).

METHODS

We drew on linked 2012-2018 Health and Retirement Study and Medicare claims for a national cohort of 1 940 community-living older adults. We described differences in HHC admission, length of stay, and referral source by patient dementia status and used weighted, multivariable logistic and negative binomial models to estimate the relationship between dementia and HHC visit type and intensity while adjusting for sociodemographic characteristics, health and functional status, and geographic/community factors.

RESULTS

PLwD had twice the odds of using HHC during a 2-year observation period, compared to those without dementia (odds ratio [OR]: 2.03; p < .001). They were more likely to be referred to HHC without a preceding hospitalization (49.4% vs 32.1%; p < .001) and incurred a greater number of HHC episodes (1.4 vs 1.0; p < .001) and a longer median HHC length of stay (55.8 days vs 40.0 days; p < .001). Among post-acute HHC patients, PLwD had twice the odds of receiving social work services (unadjusted odds ratio [aOR]: 2.15; p = .008) and 3 times the odds of receiving speech-language pathology services (aOR: 2.92; p = .002).

CONCLUSIONS

Findings highlight HHC's importance as a care setting for community-living PLwD and indicate the need to identify care delivery patterns associated with positive outcomes for PLwD and design tailored HHC clinical pathways for this patient subpopulation.

Scaled TelePhysical Therapy Program a Promising Option for Post-acute Care of Lower-Extremity Arthroplasty Patients

Background

Post-acute care for orthopedic surgery patients continues to evolve with the reduction in hospital length of stay (LOS), shift to ambulatory surgery, increased number of surgeries, and focus on value-based care.

Purpose

We sought to examine outcomes of a cohort of lower-extremity arthroplasty patients receiving telephysical therapy (TelePT) according to hospital LOS, as a means of exploring the viability of TelePT as a value-based discharge option.

Methods

A retrospective review was conducted of patients who participated in our institution's HSS@Home TelePT program after undergoing primary unilateral hip or knee arthroplasty, unicondylar knee replacement, or hip resurfacing. Demographic data and outcomes such as hospital LOS, number of days between discharge and TelePT evaluation, number of TelePT visits, number of re-admissions, Hip dysfunction and Osteoarthritis Outcome (HOOS Jr.) or Knee injury and Osteoarthritis Outcome (KOOS Jr.) scores, and patient satisfaction scores were collected. Patients were divided into categories based on hospital LOS to help determine the versatility of program.

Results

In the 2814 patients included, we observed an average of 4.1 TelePT visits; 1% of patients were readmitted within 90 days, and 97% of patients were satisfied or highly satisfied. There was no difference in HOOS or KOOS Jr. scores at each follow-up time point, except for the 6-month HOOS Jr. scores.

Conclusion

This retrospective study suggests that TelePT may be a viable option for care of lower-extremity arthroplasty patients in the post-acute setting, regardless of hospital LOS. As a discharge option, it may meet the needs of select patients to fill a gap in providing value-based care.

Home-based immersive virtual reality physical rehabilitation in paediatric patients for upper limb motor impairment: a feasibility study

Upper limb motor impairment (ULMI) rehabilitation is a long-term, demanding and challenging process to recover motor functionality. Children and adolescents may be limited in daily life activities due to reduced functions such as decreased joint movement or muscle weakness. Home-based therapy with Immersive Virtual Reality can offer greater accessibility, delivery and early rehabilitation to significantly optimise functional outcomes and quality of life. This feasibility study aimed to explore the perceptions and impacts of an immersive and interactive VR scenario suitable for ULMI rehabilitation for children at home. It was analysed using mixed methods (quantitative and qualitative) and from a multidirectional perspective (patients, clinicians and family members). Amongst the main results, it was found that IVR for ULMI home rehabilitation (1) is easy to learn and acceptable; (2) improves motor function; (3) reduces the difficulty in the reproduction of therapeutic movements; (4) is motivating and enjoyable and (5) improves quality of life. This study is the first study on the use of IVR applied to home rehabilitation of ULMI in children. These results suggested that similar outcomes may be possible with self-directed IVR home rehabilitation compared to face to face conventional rehabilitation, which can be costly to both the patient and the healthcare system, decreasing the length of stay at the hospital and treatment duration. It has also presented an innovative solution to the Covid-19 emergency where children could not receive their clinic therapy. Further research is recommended to understand better the mechanisms involved in physiotherapeutic recovery and how IVR rehabilitation helps to improve conventional treatments.

Systematic Review of Rural and Urban Differences in Care Provided by Home Health Agencies in the United States

OBJECTIVE

Home health care agencies (HHAs) are skilled care providers for Medicare home health beneficiaries in the United States. Rural HHAs face different challenges from their urban counterparts in delivering care (eg, longer distances to travel to patient homes leading to higher fuel/travel costs and fewer number of visits in a day, impacting the quality of home health care for rural beneficiaries). We review evidence on differences in care outcomes provided by urban and rural HHAs.

DESIGN

Systematic review guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines and using the Newcastle-Ottawa Scale (NOS) for quality appraisal.

SETTING

Care provided by urban and rural HHAs.

METHODS

We conducted a systematic search for English-language peer-reviewed articles after 2010 on differences in urban and rural care provided by U.S. HHAs. We screened 876 studies, conducted full-text abstraction and NOS quality review on 36 articles and excluded 2 for poor study quality.

RESULTS

Twelve studies were included; 7 focused on patient-level analyses and 5 were HHA-level. Nine studies were cross-sectional and 3 used cohorts. Urban and rural differences were measured primarily using a binary variable. All studies controlled for agency-level characteristics, and two-thirds also controlled for patient characteristics. Rural beneficiaries, compared with urban, had lower home health care utilization (4 of 5 studies) and fewer visits for physical therapy and/or rehabilitation (3 of 5 studies). Rural agencies had lower quality of HHA services (3 of 4 studies). Rural patients, compared with urban, visited the emergency room more often (2 of 2 studies) and were more likely to be hospitalized (2 of 2 studies), whereas urban patients with heart failure were more likely to have 30-day preventable hospitalizations (1 study).

CONCLUSION AND IMPLICATIONS

This review highlights similar urban/rural disparities in home health care quality and utilization as identified in previous decades. Variables used to measure the access to and quality of care by HHAs varied, so consensus was limited. Articles that used more granular measures of rurality (rather than binary measures) revealed additional differences. These findings point to the need for consistent and refined measures of rurality in studies examining urban and rural differences in care from HHAs.

Total Joint Arthroplasty Training (Prehabilitation and Rehabilitation) in Lower Extremity Arthroplasty

Lower extremity total joint arthroplasty (TJA) has an established track record of success and a subset of patients who fail to experience desired improvements. Current TJA success can be attributed to refined surgical techniques, improved preparation of patients for surgery, and enhanced postoperative recovery protocols. One aspect of preoperative patient preparation and enhanced postoperative recovery includes training regimens intended to prepare patients for TJA and facilitate TJA functional recovery (often referred to as using the jargon prehabilitation and rehabilitation). The importance of prehabilitation and rehabilitation is open to debate because of historically insufficient and inconsistent evidence. This review aims to provide direction for future investigative efforts by presenting an overview of current preoperative and postoperative TJA training/exercise programs within the framework of utility, timing, form, setting, and cost.

Total Knee Arthroplasty Assessments Should Include Strength and Performance-Based Functional Tests to Complement Range-of-Motion and Patient-Reported Outcome Measures

Range of motion (ROM) and pain often define successful recovery after total knee arthroplasty (TKA), but these routine clinical outcomes correlate poorly or not at all to functional capacity after TKA. The purpose of this Perspective is to underscore the importance of muscle strength and performance-based functional tests in addition to knee ROM and patient-reported outcome (PRO) measures to evaluate outcomes after TKA. Specifically: (1) muscle strength is the rate-limiting step for recovery of function after TKA; (2) progressive rehabilitation targeting early quadriceps muscle strengthening improves outcomes and does not compromise ROM after TKA; (3) ROM and PROs fail to fully capture functional limitations after TKA; and (4) performance-based functional tests are critical to evaluate function objectively after TKA. This Perspective also addresses studies that question the need for or benefit of physical therapy after TKA because their conclusions focus only on ROM and PRO measures. Future research is needed to determine the optimal timing, delivery, intensity, and content of physical therapy.

Poor Recovery of Activities-of-Daily-Living Function Is Associated With Higher Rates of Postsurgical Hospitalization After Total Joint Arthroplasty

OBJECTIVE

Medicare beneficiaries are increasingly using home health (HH) as the first postacute care setting after hospital discharge following total joint arthroplasty (TJA). Yet, prior research has shown that changes in payment models for TJA may negatively influence functional outcomes for Medicare beneficiaries. The purpose of this study was to evaluate the impact of poor functional outcomes during an HH episode of care on hospitalization risk for older recipients of TJA.

METHODS

For this study, 5822 Medicare beneficiaries who underwent elective TJA and subsequently participated in HH care following hospital discharge were identified using Medicare hospitalizations records and HH claims. Recovery of activities-of-daily-living (ADL) function was evaluated using patient assessment data completed at HH admission and discharge from the Medicare Outcomes and Assessment Information Set (OASIS). Hospitalization outcomes were captured from Medicare hospital claims. Cox proportional hazards regression was used to evaluate the hazard ratio for hospitalization after HH discharge.

RESULTS

The 5822 Medicare beneficiaries who received a TJA and subsequently were discharged to HH were evaluated (n = 3989 [68.6%] following total knee replacement, n = 1883 [31.4%]) following total hip replacement). Nearly 9% (n = 534) of patients did not improve their ability to perform ADLs during the HH episode; this lack of improvement was associated with a more than 2-fold increase in hospital readmission rate following HH discharge (2.3% vs 4.9%). In adjusted models, there was a significant 77% increase (hazard ratio = 1.77; 95% CI = 1.14-2.74) in hospitalization risk during the 90-day postsurgical period.

CONCLUSION

Poor recovery of ADL function in HH settings following TJA is strongly associated with elevated risk of future hospitalizations.

IMPACT

Medicare beneficiaries who fail to make substantive improvements in basic ADL function during HH care episodes following TJA may need intensive monitoring from interdisciplinary team members across the continuum of care, especially during transitions from home care to outpatient care.

LAY SUMMARY

An increasing number of patients receive home health care after joint replacement surgery, but outcomes after home health are unclear. These findings suggest that improvements in basic tasks such as walking or bathing are associated with a lower likelihood of hospitalization.

Impact of Dementia on Patterns of Home Care After Inpatient Rehabilitation Discharge for Older Adults After Hip Fractures

OBJECTIVE

To describe differences in home care use in the 30 days after discharge from inpatient rehabilitation after a hip fracture among older adults with dementia compared with those without dementia.

DESIGN

Retrospective cohort study of individually linked health administrative data.

SETTING

Community-dwelling older adults after discharge from inpatient rehabilitation facilities in Ontario, Canada.

PARTICIPANTS

A total of 17,263 older adults (N=17,263), of whom 2489 had dementia (14.4%), who were treated for hip fracture in acute care and then admitted to inpatient rehabilitation facilities between January 1, 2011 and March 31, 2017.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

The proportion receiving home care services and number of visits (physiotherapy, occupational therapy, nursing, personal/homemaking) in the 30 days after discharge were compared by dementia status with multivariate models, stratified by sex.

RESULTS

Compared with those without dementia, adults with dementia were older, had lower functional scores, and were more likely to receive home care services in the 30 days after discharge from inpatient rehabilitation (87.0% vs 79.0%, P<.001), including personal/homemaking services (66.1% vs 46.4%, P<.001) and occupational therapy (45.3% vs 37.4, P<.001) but not physiotherapy (55.8% vs 56.2%, P=.677) or nursing (19.6% vs 18.7%, P=.268). After adjustment, older adults with dementia were more likely to receive home care in both men (odds ratio [OR] =2.01; 95% confidence interval [CI], 1.57-2.57) and women (OR=1.50; 95% CI, 1.30-1.74) as well as more services (rate ratio men=1.60; 95% CI, 1.44-1.79; rate ratio women=1.50; 95% CI, 1.41-1.60).

CONCLUSIONS

Among older adults discharged from inpatient rehabilitation, older adults with dementia received home care services more often than older adults without dementia. However, irrespective of sex and dementia status, almost half of this population (44%) did not receive physiotherapy. We recommend that, resources permitting, all older adults receive physiotherapy to facilitate recovery.

Postacute Care Disposition for Total Hip and Total Knee Replacement Surgery for Asian Americans

This study explored differences in postacute disposition for total hip arthroplasty (THA) and total knee arthroplasty (TKA) with a focus on whether Asian Americans (AS) experience joint replacement disparities observed in other racial/ethnic minorities compared with majority white patients. We used data from the Nationwide Inpatient Sample for 2009 through 2012. We looked at disposition to home health care (HHC) and transfer to another facility for postacute care (e.g., skilled nursing facility, rehabilitation facility) for each of the 4 years under study. Findings for AS were mixed. There were differences in discharge to postacute facilities other than HHC for AS compared with whites for THA for 2011 and 2012. For TKA, there were differences in disposition to HHC for Asians compared with whites for 2009 and 2012; for disposition to postacute facilities other than HHC for TKA, there were differences for 2011 and 2012 only. Differences for AS in postacute disposition to facilities other than HHC appear to increase over the 4 years of the study. Further research with additional data is warranted.

Functional outcome in home health: Do racial and ethnic minority patients with dementia fare worse?

Objectives

Evaluate the independent and interactive effects of dementia and racial/ethnic minority status on functional outcomes during a home health (HH) admission among Medicare beneficiaries.

Methods

Secondary analysis of data from the Outcome and Assessment Information Set [OASIS] and billing records in a non-profit HH agency in New York. Participants were adults ≥ 65 years old who received HH in CY 2017 with OASIS records at HH admission and HH discharge. Dementia was identified by diagnosis (ICD-10 codes) and cognitive impairment (OASIS: M1700, M1710, M1740). We used OASIS records to assess race/ethnicity (M0140) and functional status (M1800-M1870 on activities of daily living [ADL]). Functional outcome was measured as change in the composite ADL score from HH admission to HH discharge, where a negative score means improvement and a positive score means decline.

Results

The sample included 4,783 patients, among whom 93.9% improved in ADLs at HH discharge. In multivariable linear regression that adjusted for HH service use and covariates (R² = 0.23), being African American (β = 0.21, 95% confidence interval [CI]: 0.06, 0.35, p = 0.005) and having dementia (β = 0.51, 95% CI: 0.41, 0.62, p<0.001) were independently related to less ADL improvement at HH discharge, with significant interaction related to further decrease in ADL improvement. Relative to white patients without dementia, African American patients with dementia (β = 1.08, 95% CI: 0.81, 1.35, p<0.001), Hispanics with dementia (β = 0.92, 95% CI: 0.38, 1.47, p = 0.001) and Asian Americans with dementia (β = 1.47, 95% CI: 0.81, 2.13, p<0.001) showed the least ADL improvement at HH discharge.

Conclusion

Racial/ethnic minority status and dementia were associated with less ADL improvement in HH with independent and interactive effects. Policies should ensure that these patients have equitable access to appropriate, adequate community-based services to meet their needs in ADLs and disease management for improved outcomes.

Home Health Rehabilitation Utilization Among Medicare Beneficiaries Following Critical Illness

OBJECTIVES

Medicare beneficiaries recovering from a critical illness are increasingly being discharged home instead of to post-acute care facilities. Rehabilitation services are commonly recommended for intensive care unit (ICU) survivors; however, little is known about the frequency and dose of home-based rehabilitation in this population.

DESIGN

Retrospective analysis of 2012 Medicare hospital and home health (HH) claims data, linked with assessment data from the Medicare Outcomes and Assessment Information Set.

SETTING

Participant homes.

PARTICIPANTS

Medicare beneficiaries recovering from an ICU stay longer than 24 hours, who were discharged directly home with HH services within 7 days of discharge and survived without readmission or hospice transfer for at least 30 days (n = 3,176).

MEASUREMENTS

Count of rehabilitation visits received during HH care episode.

RESULTS

A total of 19,564 rehabilitation visits were delivered to ICU survivors over 118,145 person-days in HH settings, a rate of 1.16 visits per week. One-third of ICU survivors received no rehabilitation visits during HH care. In adjusted models, those with the highest baseline disability received 30% more visits (rate ratio [RR] = 1.30; 95% confidence interval [CI] = 1.17-1.45) than those with the least disability. Conversely, an inverse relationship was found between multimorbidity (Elixhauser scores) and count of rehabilitation visits received; those with the highest tertile of Elixhauser scores received 11% fewer visits (RR = .89; 95% CI = .81-.99) than those in the lowest tertile. Participants living in a rural setting (vs urban) received 6% fewer visits (RR = .94; 95% CI = .91-.98); those who lived alone received 11% fewer visits (RR = .89; 95% CI = .82-.96) than those who lived with others.

CONCLUSION

On average, Medicare beneficiaries discharged home after a critical illness receive few rehabilitation visits in the early post-hospitalization period. Those who had more comorbidities, who lived alone, or who lived in rural settings received even fewer visits, suggesting a need for their consideration during discharge planning.

Determination of Postacute Hospitalization Level of Care

In the United States, we are blessed with many options for postacute care: inpatient rehabilitation facilities, long-term acute care hospitals, skilled nursing facilities, home health agencies, and outpatient rehabilitation. However, choosing the appropriate level of care can be a daunting task. It requires interdisciplinary input and involvement of all stakeholders. The decision should be informed by outcomes data specific to the patient's diagnosis, impairments, and psychosocial supports.

Preoperative Activities of Daily Living Dependency is Associated With Higher 30-Day Readmission Risk for Older Adults After Total Joint Arthroplasty

BACKGROUND

With recent Medicare payment changes, older adults are increasingly likely to be discharged home instead of to extended care facilities after total joint arthroplasty (TJA), and may therefore be at increased risk for readmissions. Identifying risk factors for readmission could help re-align care pathways for vulnerable patients; recent research has suggested preoperative dependency in activities of daily living (ADL) may increase perioperative and postoperative surgical complications. However, the proportion of older surgical patients with ADL dependence before TJA, and the impact of ADL dependency on the frequency and timing of hospital readmissions is unknown.

QUESTIONS/PURPOSES

(1) What proportion of older adults discharged home after TJA have preoperative ADL dependency? (2) Is preoperative ADL dependency associated with increased risk of hospital readmissions at 30 days or 90 days for older adults discharged home after TJA?

METHODS

This was a retrospective cohort analysis of 6270 Medicare fee-for-service claims from 2012 from a 5% national Medicare sample for older adults (older than 65 years) receiving home health care after being discharged to the community after elective TJA. Medicare home health claims were used for two reasons: (1) the primary population of interest was older adults and (2) the accompanying patient-level assessment data included an assessment of prior dependency on four ADL tasks. Activities of daily living dependency was dichotomized as severe (requiring human assistance with all four assessed tasks) or partial/none (needing assistance with three or fewer ADLs); this cutoff has been used in prior research to evaluate readmission risk. Multivariable logistic regression models, clustered at the hospital level and adjusted for known readmission risk factors (such as comorbidity status or age), were used to model the odds of 30- and 90- day and readmission for patients with severe ADL dependence.

RESULTS

Overall, 411 patients were hospitalized during the study period. Of all readmissions, 64% (262 of 411) occurred within the first 30 days, with a median (interquartile range [IQR]) time to readmission of 17 days (5 to 46). Severe ADL dependency before surgery was common for older home health recipients recovering from TJA, affecting 17% (1066 of 6270) of our sample population. After adjusting for clinical covariates, severe ADL dependency was not associated with readmissions at 90 days (adjusted odds ratio = 1.20 [95% CI 0.93 to 1.55]; p = 0.15). However, severe preoperative ADL dependency was associated with higher odds of readmission at 30 days (adjusted OR = 1.45 [95% CI 1.11 to 1.99]; p = 0.008).

CONCLUSIONS

Severe preoperative ADL dependency is modestly associated with early but not late hospital readmission after TJA. This work demonstrates that it may important to apply a simple screening of ADL dependency preoperatively so that surgeons can guide changes in care planning for older adults undergoing TJA, which may include participation in preoperative rehabilitation (pre-habilitation) or more aggressive follow-up in the 30 days after surgery. Further research is needed to determine whether severe ADL dependence can be modified before surgery, and whether these changes in dependency can reduce readmission risk after TJA.

LEVEL OF EVIDENCE

Level III, therapeutic study.

Establishing a patient centered, outpatient total joint home recovery program within an integrated healthcare system

Outpatient total joint home recovery (HR) is a rapidly growing initiative being developed and employed at high volume orthopedic centers. Minimally invasive surgery, improved pain control and home health services have made HR possible. Multidisciplinary teams with members ranging from surgeons and anesthesiologists to hospital administrators, physical therapists, nurses and research analysts are necessary for success. Eligibility criteria for outpatient total joint arthroplasty will vary between medical centers. Surgeon preference in addition to medical comorbidities, social support, preoperative patient mobility and safety of the HR location are all factors to consider when selecting patients for outpatient total joint HR. As additional knowledge is gained, the next steps will be to establish 'best practices' and speciality society-endorsed guidelines for patients undergoing outpatient total joint arthroplasty.

Ambulation milestones in post-operative physical therapy after total knee arthroplasty: how can we improve short-term outcomes?

Introduction: Post-operative day (POD) 0 physical therapy (PT) after total knee arthroplasty (TKA) has been associated with improved outcomes such as shorter hospital length of stay (LOS), though patient performance is variable. The purpose of this study was to evaluate PT performance and determine whether this affected LOS or discharge to home.Methods: Retrospective review including 412 patients who underwent TKA over 1 year. Specific data assessed included details about demographics, surgery/recovery, PT, LOS, and discharge destination.Results: Overall, 88.8% (366/412) of patients received POD 0 PT. About 73.9% of patients who did not receive POD 0 PT were prevented from doing so by reasons that kept them off of the orthopedic inpatient floor. Patients who walked greater than 10 feet on POD 0 or 100 feet on POD 1 were significantly more likely to have a shorter LOS and more likely to be discharged to home.Discussion: Objective milestones of walking 10 feet on POD 0 and 100 feet on POD 1 were associated with improved short-term outcomes. These performance markers may be useful for stratifying which patients are meeting milestones for early discharge. Late arrival to inpatient floor had the strongest associations with inability to perform PT.

HSS@Home, Physical Therapist-Led Telehealth Care Navigation for Arthroplasty Patients: A Retrospective Case Series

BACKGROUND

As the rate of total joint arthroplasties performed in the USA continues to increase, so does the push for more value-based care. Bundled payments have encouraged organizations to be creative in limiting care overuse. Telehealth is one option for caring for arthroplasty patients post-surgery while limiting costs and improving communication with the surgical team.

QUESTIONS/PURPOSES

We sought to determine the effects of the implementation of HSS@Home, a telehealth rehabilitation program that uses patients' existing technology, in patients after they had undergone total knee or total hip arthroplasty.

METHODS

In this retrospective case series, of 32 patients referred, 19 patients (nine men and ten women; average age, 69 years) were enrolled in HSS@Home after undergoing a pre- and post-operative screening process. Telehealth video visits were conducted, wherein a physical therapy navigator assisted patients in following exercise and mobility programs, addressing patients' concerns while transitioning to outpatient therapy. Patients were seen within 24 h of hospital discharge, 3 times a week for 3 weeks, for an average of 11 sessions. Episodes of care were recorded in the patient's electronic medical record.

RESULTS

There were no readmissions among the 19 patients. Nurse practitioners were consulted for all patients, predominantly for non-emergent reasons. Feedback from patients and physicians was positive, and no overutilization of care was found.

CONCLUSION

HSS@Home was a promising alternative to live, in-home physical therapy that was effective in monitoring this series of patients after hip or knee arthroplasty. This preliminary data sets the stage for further research into the use of telehealth technology to provide rehabilitative care to arthroplasty patients.

Ninety-day and one-year healthcare utilization and costs after knee arthroplasty

OBJECTIVES

This study examined ninety-day and one-year postoperative healthcare utilization and costs following total knee arthroplasty (TKA) from the health sector and patient perspectives.

DESIGN

This study relied on: 1) patient-reported medical resource utilization data from diaries in the Knee Arthroplasty Pain Coping Skills Training (KASTPain) trial; and 2) Medicare fee schedules. Medicare payments, patient cost-sharing, and patient time costs were estimated. Generalized linear mixed models were used to identify baseline predictors of costs.

RESULTS

In the first ninety days following TKA, patients had an average of 29.7 outpatient visits and 6% were hospitalized. Mean total costs during this period summed to $3,720, the majority attributed to outpatient visit costs (84%). Over the year following TKA, patients had an average of 48.9 outpatient visits, including 33.2 for physical therapy. About a quarter (24%) of patients were hospitalized. Medical costs were incurred at a decreasing rate, from $2,428 in the first six weeks to $648 in the last six weeks. Mean total medical costs across all patients over the year were $8,930, including $5,328 in outpatient costs. Total costs were positively associated with baseline Charlson comorbidity score (P < 0.01). Outpatient costs were positively associated with baseline Charlson comorbidity score (P = 0.03) and a bodily pain burden summary score (P < 0.01). Mean patient cost-sharing summed to $1,342 and time costs summed to $1,346.

CONCLUSIONS

Costs in the ninety days and year after TKA can be substantial for both healthcare payers and patients. These costs should be considered as payers continue to explore alternative payment models.

Changes in Discharge to Rehabilitation: Potential Unintended Consequences of Medicare Total Hip Arthroplasty/Total Knee Arthroplasty Bundled Payments, Should They Be Implemented on a Nationwide Scale?

BACKGROUND

As a part of the 2010 Affordable Care Act, Medicare was committed to changing 50% of its reimbursement to alternative payment models by 2018. One strategy included introduction of "bundled payments" or a fixed price for an episode of care. Early studies of the first operative bundles for elective total hip and knee arthroplasty (THA/TKA) suggest changes in discharge to rehabilitation. It remains unclear the extent to which such changes affect patient well-being. In order to address these concerns, the objective of this study is to estimate projected changes in discharge to various type of rehabilitation, 90-day outcomes, extent of therapy received, and patient health-related quality-of-life before and after introduction of bundled payments should they be implemented on a nationwide scale.

METHODS

A nationwide policy simulation was conducted using decision-tree methodology in order to estimate changes in overt and patient-centered outcomes. Model parameters were informed by published research on bundled payment effects and anticipated outcomes of patients discharged to various types of rehabilitation.

RESULTS

Following bundled payment introduction, discharge to inpatient rehabilitation facilities decreased by 16.9 percentage-points (95% confidence interval [CI] 16.5-17.3) among primary TKA patients (THA 16.8 percentage-points), a relative decline from baseline of 58.9%. Skilled nursing facility use fell by 24.0 percentage-points (95% CI 23.6-24.4). It was accompanied by a 36.7 percentage-point (95% CI 36.3-37.2) increase in home health agency use. Although simulation models predicted minimal changes in overt outcome measures such as unplanned readmission (TKA +0.8 percentage-points), changes in discharge disposition were accompanied by significant increases in the need for further assistive care (TKA +8.0 percentage-points) and decreases in patients' functional recovery and extent of therapy received. They collectively accounted for a 30% reduction in recovered motor gains.

CONCLUSION

The results demonstrate substantial changes in discharge to rehabilitation with accompanying declines in average functional outcomes, extent of therapy received, and health-related quality-of-life. Such findings challenge notions of reduced cost at no harm previously attributed to the bundled payment program and lend credence to concerns about reductions in access to facility-based rehabilitation.

Medium-Term Outcomes of Digital Versus Conventional Home-Based Rehabilitation After Total Knee Arthroplasty: Prospective, Parallel-Group Feasibility Study

Background

Physical rehabilitation is recommended after total knee arthroplasty (TKA). With the expected increase in TKA over the next few decades, it is important to find new ways of delivering cost-effective interventions. Technological interventions have been developed with this intent, but only preliminary evidence exists regarding their validity, with short follow-up times.

Objective

This study aimed to present the follow-up results of a feasibility study comparing two different home-based programs after TKA: conventional face-to-face sessions and a digital intervention performed through the use of an artificial intelligence-powered biofeedback system under remote clinical monitoring.

Methods

The digital intervention uses a motion tracker allowing 3D movement quantification, a mobile app and a Web portal. This study presents the results of the previous single-center, prospective, parallel-group, feasibility study including an 8-week active treatment stage and further assessments at 3 and 6 months post-TKA. Primary outcome was the Timed Up and Go score, and secondary outcomes were the Knee Osteoarthritis Outcome Scale (KOOS) score and knee range of motion.

Results

A total of 59 patients completed the study (30 in the digital intervention group and 29 in the conventional rehabilitation group) and follow-up assessments. During the active treatment stage, patients in the digital intervention group demonstrated high engagement and satisfaction levels, with an 82% retention rate. Both groups attained clinically relevant improvements from baseline to 6 months post-TKA. At the end of the 8-week program, clinical outcomes were superior in the digital intervention group. At the 3- and 6-month assessments, the outcomes remained superior for the Timed Up and Go score (P<.001) and all KOOS subscale scores (at 3 months, P<.001 overall; at 6 months, KOOS Symptoms: P=.006, Pain: P=.002, Activities of Daily Living: P=.001, Sports: P=.003, and Quality of Life: P=.001). There was progressive convergence between both groups in terms of the knee range of motion, which remained higher for standing flexion in the digital intervention group than the conventional group at 6 months (P=.01). For the primary outcome, at 6 months, the median difference between groups was 4.87 seconds (95% CI 1.85-7.47), in favor of the digital intervention group.

Conclusions

The present study demonstrates that this novel digital intervention for independent home-based rehabilitation after TKA is feasible, engaging, and capable of maximizing clinical outcomes in comparison to conventional rehabilitation in the short and medium term; in addition, this intervention is far less demanding in terms of human resources.
