Comparison of Functional Status Improvements Among Patients With Stroke Receiving Postacute Care in Inpatient Rehabilitation vs Skilled Nursing Facilities

The Case for Aggregated Rehabilitation-Relevant Data Across Health Care Systems and Settings

Health care value, quantified as outcome per unit cost, requires knowing which outcomes are influenced by which intervention at what cost. The value of rehabilitation is still largely unknown. Much of the reason for this limited evidence is historically poor standardization and collection of rehabilitation interventions, and objectively measured outcomes across care settings, care providers, and health care systems. The purposeful standardization and aggregation of rehabilitation-relevant data about interventions, cost, and outcomes from routine clinical practices offers potential to understand and improve the value of rehabilitation. This perspective details the critical need for rehabilitation-relevant data that are aggregated across settings, providers, and systems and proposes 3 options to meet this need, including (1) integrating rehabilitation-relevant data into existing research registry databases that are condition specific, (2) adding rehabilitation-relevant data to federally funded research networks, and (3) creating a novel rehabilitation registry database. There must be continued pursuit of discovering which rehabilitation interventions achieve which specific outcomes, in which settings, for which patients, and at what costs. Successfully aggregating rehabilitation-relevant data is critical for generating evidence that answers these key questions about the value of rehabilitation.

Racial and ethnic disparities in post-acute care service utilization after stroke

Evidence examining disparities in post-acute care (PAC) utilization among various racial and ethnic groups after stroke and the influence of social determinants of health (SDOH) in these decisions is lacking. Thus, we searched the literature from January 2000 to November 2023 regarding PAC among individuals after stroke through: 1) Pubmed, 2) Scopus, 3) Web of Science, 4) Embase, and 5) CINAHL. We found 14 studies. Black individuals were more likely than White individuals to be discharged home with home health (HH) and skilled nursing facilities (SNF). Hispanic individuals were more likely than White individuals to be discharged home with HH, but less likely to be discharged to institutions. Lower socioeconomic status, Medicaid insurance, urban residence, area PAC supply and hospital characteristics were associated with increased institutional discharges among racial and ethnic minority individuals. Future policy should improve access to appropriate PAC commensurate with an individual's medical/social complexity.

Awaiting insurance coverage: Medicaid enrollment and post-acute care use after traumatic injury

BACKGROUND

Lack of insurance after traumatic injury is associated with decreased use of postacute care and poor outcomes. Insurance linkage programs enroll eligible patients in Medicaid at the time of an unplanned admission. We hypothesized that Medicaid enrollment would be associated with increased use of postacute care, but also with prolonged hospital length of stay (LOS) while awaiting insurance authorization.

METHODS

We linked trauma registry and EMR data to identify patients ages 18 years to 64 years admitted from 2017 to 2021 to a Level I trauma center. Patients admitted without insurance and retroactively insured (RI) during hospitalization were compared with patients with established Medicaid (MI) and those remaining uninsured (UI). We measured postacute care use including home health care, rehabilitation, and skilled nursing facilities. We tested the association between insurance status and discharge disposition and LOS (primary outcome) using multivariable negative binomial regression. Direct costs were compared between groups.

RESULTS

We compared 494 RI patients to 1706 MI and 148 UI patients. Retroactively insured patients had longer hospitalization (median LOS [interquartile range], 4 days [2-9 days]) than other groups (MI, 4 [2-8] and UI 2 [1-3]), p < 0.001). Retroactively insured patients were more likely to be discharged with home health care and to inpatient rehabilitation than UI patients ( p < 0.001). After adjusting for injury and management characteristics, RI was associated with longer LOS compared with MI for patients discharged to inpatient facilities ( p < 0.001). Median costs for RI patients discharged to a facility were $10,284 higher than MI patients, ranging from $8,582 for Injury Severity Score <9 to $51,883 for Injury Severity Score ≥25.

CONCLUSION

Enrollment in Medicaid after traumatic injury is associated with postacute care use, but the current enrollment process may delay discharge. Streamlining insurance enrollment and permitting discharge with pending application status could reduce unnecessary hospital days, saving costs and improving improve patient experience.

LEVEL OF EVIDENCE

Association of Calf Circumference, Hand Grip Strength, and Physical Performance With Serious Adverse Events in Individuals With Subacute Stroke Hospitalized for Rehabilitation: An Observational Study

OBJECTIVE

To determine whether calf circumference, hand grip strength, and physical performance are linked to the incidence of serious adverse events (SAEs) in patients with subacute stroke.

DESIGN

Retrospective cohort study.

SETTING

Single rehabilitation hospital.

PARTICIPANTS

Patients with stroke admitted for rehabilitation hospital.

INTERVENTION

Not applicable.

MAIN OUTCOME MEASURES

The incidence of SAEs, such as death, cardiovascular events including recurrent stroke, and conditions requiring transfer to another hospital for specialized care or immediate treatment for an acute illness during hospitalization.

RESULTS

A total of 341 patients (median age: 74y) participated in this study, with 232 patients (68%) exhibiting low-physical performance. In the adjusted model, low-physical performance was significantly associated with SAEs (hazard ratio [HR], 3.01; 95% confidence interval [CI], 1.04-8.68; P=.042). However, low calf circumference (HR, 1.60; 95% CI, 0.76-3.38; P=.219) and low hand grip strength (HR, 0.98; 95% CI, 0.39-2.42; P=.960) did not show an independent association.

CONCLUSIONS

Low-physical performance was independently associated with the occurrence of SAEs during hospitalization for rehabilitation in patients with subacute stroke.

Predictors of Skilled Nursing Facility Length of Stay and Discharge After Aneurysmal Subarachnoid Hemorrhage

Background and Purpose

Aneurysmal subarachnoid hemorrhage (aSAH) carries high morbidity and mortality with survivors often requiring extended care at skilled nursing facilities (SNF). Predictors of SNF discharge to home (SNFdcH) remain unclear.

Methods

Retrospective review of a single-center prospectively maintained aSAH database from June 2016-March 2024 was conducted. Patients discharged to SNF were grouped by subsequent discharge to home. Predictors of discharge to home and facility length of stay (LOS) were determined using t-tests, Fisher analyses, and cumulative link modeling.

Results

Of 450 aSAH patients, 61 (13.5%) were discharged to SNFs. 49 (80.3%) returned home, with 61% achieving mRS <3 at discharge. Discharged patients were younger (mean 63.3 ± 11.5 vs 70.2 ± 9.3 years, P = .040) with lower median modified Fisher scores (3 [IQR 3-4] vs 4 [4-4], P = .046). Tracheostomy (OR = .14, 95% CI [.02, .75], P = .023) and gastrostomy tube (PEG) placement (OR = .13, 95% CI: .03-.51, P = .003) decreased the odds of SNFdcH. Discharged patients had shorter hospital LOS (26 ± 10 vs 39 ± 15 days, P < .001) and lower median modified Rankin scores (mRS) at hospital discharge (4 [4-5] vs 5 [4-5], P = .028) and at 90 days post-discharge (4 [3-5] vs 6 [5-6], P = .001). Multivariable regression identified age, PEG, and hospital LOS as predictors of SNFdcH. Tracheostomy and PEG predicted SNF LOS.

Conclusions

Most aSAH patients discharged from SNFs returned home, with 61% achieving mRS <3. Patients not discharged were medically complex with neurological deficits. These findings may guide care discussions and highlight the role of SNFs in bridging hospitalization and independence.

Motivation in veterans with an acute/subacute ischemic stroke did not improve cognition and functional motor recovery but reduced deaths

BACKGROUND

The role of motivation per se in the presence or absence of depression in stroke-related cognitive and functional motor recovery has not been studied.

AIM

This study aimed to determine the role of motivation on cognition and functional motor recovery in patients after an acute and subacute ischemic stroke.

DESIGN

Prospective, observational, single-center study.

SETTING

Enrollment was undertaken in an inpatient neurorehabilitation facility.

POPULATION

A total of 125 veterans with stroke were admitted to an inpatient neurorehabilitation facility.

METHODS

Recovery locus of control (RLOC) measured the degree of motivation. The primary outcome measures were changes from baseline in the Action Research Arm Test (ARAT), total and sub-scores of Functional Independence Measures (TFIM), and the 2-minute walk test (2-MWT) on discharge from the IRF.

RESULTS

The mean age of the study sample was 65±9.3 years, they were mainly non-Hispanic white (N.=92, 74%) men (N.=119, 95%) admitted 9±11 days after acute stroke. When the sample was divided into less motivated (score 0-25, N.=32) and motivated (score ≥ 26, N.=93) as measured by the total RLOC for a statistical median of 26, the two groups had similar baseline characteristics including admission depression, TFIM, ARAT, and 2-MWT scores. The change in the primary outcome measure scores from baseline was similar between the two groups. Motivated group veterans had a lower all-cause mortality rate at 12 months than less motivated veterans (P=0.001).

CONCLUSIONS

A higher level of motivation irrespective of the degree of depression did not improve cognitive or functional motor recovery scores. However, motivated veterans had a lower all-cause mortality at 12 months.

CLINICAL REHABILITATION IMPACT

The result of this study has important implications in clinical practice highlighting that motivated patients are more likely to be discharged home and have a lower all-cause mortality.

Trends in performance of thrombectomy for acute ischemic stroke patients in teaching and non-teaching hospitals

OBJECTIVES

The value of thrombectomy in patients with acute ischemic stroke cannot be understated. As such, whether these patients get access to this treatment can significantly impact their disease outcomes. We analyzed the trends in thrombectomy adoption between teaching and non-teaching hospitals in the United States, and their impact on overall patient care.

MATERIALS AND METHODS

We conducted a retrospective analysis of hospital admissions in the Nationwide Inpatient Sample with a diagnosis of acute ischemic stroke between 2012 and 2020. We compared the annual total number and proportion of patients undergoing thrombectomy between teaching and non-teaching hospitals, and their corresponding outcomes.

RESULTS

A total of 3,823,490 and 1,875,705 patients were admitted to teaching and non-teaching hospitals during the study duration, respectively. The proportion of patients who underwent thrombectomy increased from 1.60 % to 7.02 % (p-value for trend p < 0.001) in teaching hospitals and from 0.32 % to 2.20 % (p-value trend p < 0.001) in non-teaching hospitals. The absolute increase in the number of acute ischemic stroke patients undergoing thrombectomy was highest in teaching hospitals particularly those with large bed size, an increase from 3635 patients in 2012 to 24,730 patients in 2020. Higher rates of intravenous thrombolysis and patient transfer prior to thrombectomy were seen in teaching hospitals compared with non-teaching hospitals.

CONCLUSIONS

The study highlights disparities between teaching and non-teaching hospitals, with teaching hospitals showing a disproportionately higher rate of thrombectomy adoption in acute ischemic stroke patients. Further studies are needed to understand the barriers to the adoption of thrombectomy in non-teaching hospitals.

Role of inpatient rehabilitation facility functional measures to predict community discharge after stroke

BACKGROUND

This study investigated the association between stroke severity, functional status measured by the Inpatient Rehabilitation Facility-Patient Assessment Instrument (IRF-PAI), and community discharge from IRF.

OBJECTIVES

Aim one examined the association between National Institutes of Health Stroke Scale (NIHSS) scores measured during the acute care stay and IRF admission functional status, measured by the admission IRF-PAI self-care and mobility functional measures, to deduce if functional measures can serve as a proxy for stroke severity. Aim two investigated the ability of the NIHSS and IRF-PAI admission functional measures to predict community discharge from IRF after stroke.

DESIGN

Retrospective cohort study using electronic health records and Uniform Data System. Medical Record file data from January 1, 2018, to December 30, 2019.

SETTING

Academic hospital-based IRF.

PARTICIPANTS

Five hundred forty-four patients transferred from acute care hospital to IRF after an ischemic or hemorrhagic stroke. Exclusion criteria included a transient ischemic attack, discharge against medical advice, death during IRF stay, or readmission to acute care within 48 hours of IRF admission.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

Admission IRF-PAI self-care and mobility scores and discharge status from IRF.

RESULTS

Of the 544 patients, 76.7% had community discharge. NIHSS scores were significantly associated with IRF-PAI admission self-care scores across each NIHSS stroke category. There was no statistically significant association between NIHSS and IRF-PAI admission mobility score. IRF admission self-care and mobility scores were each statistically significant predictors of community discharge (odds ratio [OR] = 1.10, 95% confidence interval [CI]: 1.03-1.17; OR = 1.10, CI: 1.03-1.18, respectively). NIHSS scores were not a statistically significant predictor of community discharge (OR = 0.70, CI: 0.47-1.04) from IRF.

CONCLUSIONS

IRF-PAI self-care functional measure is associated with the NIHSS and can serve as a proxy for stroke severity. IRF-PAI self-care and mobility measures each predict community discharge.

Lost in the Shuffle: Low Health Literacy in Geriatric Fracture Patients and Families Regarding Post-Acute Care-A Prospective Study

INTRODUCTION

This study aims to evaluate health literacy (HL) in geriatric orthopaedic trauma patients and their families as it relates to their post-acute care (PAC) in skilled nursing facilities (SNFs) and inpatient rehabilitation facilities (IRFs).

METHODS

This nonrandomized controlled clinical trial included patients aged 65 years and older treated for acute fracture at a Level 1 trauma center and discharged to either IRF or SNF. First 106 patients enrolled served as the control group and received standard discharge instructions. The second 101 patients were given a set of oral and written instructions regarding PAC detailing important questions to ask upon arrival to their facility.

RESULTS

The mean HL score for all patients/families was 2.4 out of 5. No significant difference was noted in HL scores (2.4 versus 2.3) or median LOS (22 versus 28 days) between the control and intervention groups. Family involvement (68%) slightly improved HL scores (2.6 versus 1.9, P < 0.001). Patients discharged to IRF had better HL scores (3.4 versus 2.3, P < 0.001), shorter LOS (median 15 vs 30 days, P < 0.001), and trended toward improved knowledge of discharge goals (48.1% versus 35.6%) than those in SNF.

CONCLUSION

System-wide solutions are necessary to improve geriatric HL and optimize outcomes in orthopaedic trauma.

From inpatient rehabilitation facility to skilled nursing facility to home: A retrospective study of functional recovery

BACKGROUND

Inpatient rehabilitation facility (IRF) care has an inherent goal of discharging patients back into the community. Some patients do not progress sufficiently and require discharge to alternate facilities. No prior studies have examined outcomes for patients requiring skilled nursing facility (SNF) placement after their stay at an IRF.

OBJECTIVE

To identify functional outcomes of patients who receive combined rehabilitation from IRF and SNF.

DESIGN

In this retrospective observational study, a semistructured phone call questionnaire evaluated for living situation and aid requirement at two time points: prior to acute hospitalization and following discharge from SNF.

SETTING

Inpatient rehabilitation facility.

PARTICIPANTS

Persons who required postacute care stay at an IRF and who at time of discharge were not yet safe to return home, so instead were admitted to a SNF.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

Changes in pre- and postmorbid functional status categorized by living situation and aid requirement.

RESULTS

Forty-three adults completed the study. After a stay at IRF followed by SNF, 58.2% of respondents returned to baseline independence. After IRF and SNF stay, 63.4% of respondents who lived at home prior to acute hospitalization returned home.

CONCLUSIONS

The findings indicate that those patients who receive further rehabilitation at a SNF following discharge from an IRF have the potential to return to baseline functioning and subsequently return home. These data suggest that using IRFs in conjunction with SNFs might be an effective, patient-centered option for rehabilitation. However, further investigation is required to explore whether these findings may be generalized to a larger sample.

Postacute Care for Medicare Advantage Enrollees Who Switched to Traditional Medicare Compared With Those Who Remained in Medicare Advantage

Importance

Medicare Advantage (MA) plans receive capitated per enrollee payments that create financial incentives to provide care more efficiently than traditional Medicare (TM); however, incentives could be associated with MA plans reducing use of beneficial services. Postacute care can improve functional status, but it is costly, and thus may be provided differently to Medicare beneficiaries by MA plans compared with TM.

Objective

To estimate the association of MA compared with TM enrollment with postacute care use and postdischarge outcomes.

Design, Setting, and Participants

This was a cohort study using Medicare data on 4613 hospitalizations among retired Ohio state employees and 2 comparison groups in 2015 and 2016. The study investigated the association of a policy change with use of postacute care and outcomes. The policy changed state retiree health benefits in Ohio from a mandatory MA plan to subsidies for either supplemental TM coverage or an MA plan. After policy implementation, approximately 75% of retired Ohio state employees switched to TM. Hospitalizations for 3 high-volume conditions that usually require postacute rehabilitation were assessed. Data from the Medicare Provider Analysis and Review files were used to identify all hospitalizations in short-term acute care hospitals. Difference-in-difference regressions were used to estimate changes for retired Ohio state employees compared with other 2015 MA enrollees in Ohio and with Kentucky public retirees who were continuously offered a mandatory MA plan. Data analyses were performed from September 1, 2019, to November 30, 2023.

Exposures

Enrollment in Ohio state retiree health benefits in 2015, after which most members shifted to TM.

Main Outcomes and Measures

Received care in an inpatient rehabilitation facility, skilled nursing facility, or home health, or any postacute care; the occurrence of any hospital readmission; the number of days in the community during the 30 days after hospital discharge; and mortality.

Results

The study sample included 2373 hospitalizations for Ohio public retirees, 1651 hospitalizations for other Humana MA enrollees in Ohio, and 589 hospitalizations for public retirees in Kentucky. After the 2016 policy implementation, the percentage of hospitalizations covered by MA decreased by 70.1 (95% CI, -74.2 to -65.9) percentage points (pp), inpatient rehabilitation facility admissions increased by 9.7 (95% CI, 4.7 to 14.7) pp, use of only home health or skilled nursing facility care fell by 8.6 (95% CI, -14.6 to -2.6) pp, and days in the community fell by 1.6 (95% CI, -2.9 to -0.3) days for Ohio public retirees compared with other Humana MA enrollees in Ohio. There was no change in 30-day mortality or hospital readmissions; similar results were found by comparisons using Kentucky public retirees as a control group.

Conclusions and Relevance

The findings of this cohort study indicate that after a change in retiree health benefits, most Ohio public retirees shifted from MA to TM and received more intensive postacute care with no significant change in measured short-term postdischarge outcomes. Future work should consider additional measures of postacute functional status over a longer follow-up period.

[Factors Modulating Motor Function Changes in Stroke Patients During Inpatient Neurological Rehabilitation]

PURPOSE

To identify factors that have an impact on the degree of functional improvements in stroke patients during inpatient neurological rehabilitation.

METHODS

Retrospective analysis of 398 stroke patients who participated in an inpatient Phase C rehabilitation (Barthel index between 30 and 70 points). We correlated changes in 3 physiotherapeutic assessments (transfer from sitting to standing; transfer from bed to (wheel)chair; climbing stairs) and 3 occupational therapeutic assessments (eating/drinking; dressing of the upper part of the body; object manipulation) with the factors age, gender, Barthel-Index at admission, time since stroke, length of stay in inpatient rehab, number and extent of therapies and ischemic versus hemorrhagic stroke. In addition, a stepwise regression analysis was performed.

RESULTS

The patient group showed significant improvements in all assessments. Length of stay in inpatient rehab and number/extent of therapies correlated with improvements of transfer from sitting to standing, transfer from bed to (wheel)chair, climbing stairs, and dressing of the upper part of the body. Number/extent of therapies also correlated with eating/drinking. Barthel-Index at admission was negatively correlated with transfer from sitting to standing, transfer from bed to (wheel)chair, and dressing of the upper part of the body. No correlation between changes of motor functions and age or gender or type of stroke (ischemic versus hemorrhagic) was found. Patients<3 months after stroke showed stronger improvements of transfer from sitting to standing, transfer from bed to (wheel)chair, climbing stairs, dressing of the upper part of the body, and object manipulation than patients>6 months after stroke. However, patients<3 months after stroke also stayed 10 days longer in inpatient rehab. The stepwise regression analysis identified the number of physiotherapies and Barthel-Index at admission as the most important factors for changes in transfer from sitting to standing and transfer from bed to (wheel)chair, number of physiotherapies and time since stroke for climbing stairs, number of occupational therapies for eating/drinking, number of occupational therapies and time since stroke for dressing the upper part of the body and number of occupational therapies and length of inpatient rehab for object manipulation.

CONCLUSION

In stroke patients, a higher number of therapies is associated with greater improvements of motor functions. Age, gender and type of stroke have no relevant impact on changes of motor functions during inpatient rehabilitation.

The effect of post-acute rehabilitation setting on 90-day mobility after stroke: A difference-in-difference analysis

Background

After discharged from the hospital for acute stroke, individuals typically receive rehabilitation in one of three settings: inpatient rehabilitation facilities (IRFs), skilled nursing facilities (SNFs), or home with community services (i.e., home health or outpatient clinics). The initial setting of post-acute care (i.e., discharge location) is related to mortality and hospital readmission; however, the impact of this setting on the change in functional mobility at 90-days after discharge is still poorly understood. The purpose of this work was to examine the impact of discharge location on the change in functional mobility between hospital discharge and 90-days post-discharge.

Methods

In this retrospective cohort study, we used the electronic health record to identify individuals admitted to Johns Hopkins Medicine with an acute stroke and who had measurements of mobility [Activity Measure for Post Acute Care Basic Mobility (AM-PAC BM)] at discharge from the acute hospital and 90-days post-discharge. Individuals were grouped by discharge location (IRF=190 [40%], SNF=103 [22%], Home with community services=182 [(38%]). We compared the change in mobility from time of discharge to 90-days post-discharge in each group using a difference-in-differences analysis and controlling for demographics, clinical characteristics, and social determinants of health.

Results

We included 475 individuals (age 64.4 [14.8] years; female: 248 [52.2%]). After adjusting for covariates, individuals who were discharged to an IRF had a significantly greater improvement in AM-PAC BM from time of discharge to 90-days post-discharge compared to individuals discharged to a SNF or home with community services (β=-3.5 (1.4), p=0.01 and β=-8.2 (1.3), p=<0.001, respectively).

Conclusions

These findings suggest that the initial post-acute rehabilitation setting impacts the magnitude of functional recovery at 90-days after discharge from the acute hospital. These findings support the need for high-intensity rehabilitation and for policies that facilitate the delivery of high-intensity rehabilitation after stroke.

Clinical practice patterns of speech-language pathologists for screening and identifying dysphagia

PURPOSE

To identify how speech-language pathologists (SLPs) in the United States are screening for and identifying dysphagia. To do this, we examined the approaches most often used to screen for dysphagia and the influence of contextual factors such as setting, continuing education and means of staying up to date with the most current literature on screening approaches.

METHOD

A web-based survey composed of 32 questions was developed and field tested for content, relevance and workflow. The survey was distributed online, via social media, online SLP forums and through the American Speech-Language-Hearing Association's Special Interest Group 13 (swallowing disorders). One hundred and thirty-seven clinicians from the United States completed the survey and were included for analysis using descriptive statistics and linear regression modelling to assess associations of continuing education and years practicing with screening protocols and consumption of evidence.

RESULTS

Respondents worked in a variety of settings, including acute care, skilled nursing facilities, and inpatient rehabilitation. Most respondents worked with adult populations (88%). The most common screening protocols reported were a volume-dependent water swallow test (74%), subjective patient report (66%), and trials of solids/liquids (49%). Twenty-four percent (24%) reported using a questionnaire, the Eating Assessment Tool (80%) being most common. How clinicians consume their evidence was significantly associated with the types of screening approaches used. Continuing education hours were significantly associated with dysphagia screening protocol choice (p < 0.001) and how clinicians stayed up to date with evidence (p < 0.001).

CONCLUSIONS

Results from this study provide an in-depth look at the choices clinicians are making in the field regarding how to effectively screen patients for the presence of dysphagia. Contextual factors such as evidence base consumption patterns should serve researchers to continue seeking alternative ways to share evidence with clinicians, accessibly. Associations between continuing education and protocol choice show the need for continued evidence-based and high-quality continuing education opportunities.

WHAT THIS PAPER ADDS

This study provides an in-depth look at the choices clinicians are making in the field regarding effective dysphagia screening practices. Clinician screening choices are examined with contextual factors such as evidence base consumption patterns and continuing education. This paper increases knowledge of the most used dysphagia screening practices and context for clinicians and researchers to improve use, evidence and dissemination of best practices.

Physical Activity as Measured by Accelerometers Predicts Functional Improvement in Older Patients Undergoing Hospital Rehabilitation

This prospective cohort study aimed to investigate the association between physical activity (PA) as measured using accelerometers, and functional improvement measured using a short physical performance battery in older patients undergoing rehabilitation. After admission to the rehabilitation hospital, patients were categorized into quartile groups based on their level of PA measured using accelerometers. The primary outcome was physical function measured using the short physical performance battery at hospital discharge. A total of 204 patients were included in the analysis. After adjusting for confounding factors, light-intensity PA (p < .001) and moderate-to-vigorous-intensity PA (p < .001) were associated with a short physical performance battery at hospital discharge. In conclusion, PA at admission is positively associated with functional improvement in older patients undergoing hospital rehabilitation.

Effect of inpatient rehabilitation facility care on ninety day modified Rankin score in ischemic stroke patients

OBJECTIVE

To determine Inpatient Rehabilitation Facility (IRF) treatment effect on modified Rankin Scale (mRS) scores at 90 days in acute ischemic stroke (AIS) patients.

MATERIALS AND METHODS

This prospective cross-sectional study included 738 AIS patients admitted 1/1/2018-12/31/2020 to a Comprehensive Stroke Center with a Stroke Rehabilitation program. We compared outcomes for patients who went directly home versus went to IRF at hospital discharge: (1) acute care length of stay (LOS), (2) National Institutes of Health Stroke Scale (NIHSS) score, (3) mRS score at hospital discharge and 90 days, (4) the proportion of mRS scores ≤ 2 from hospital discharge to 90 days.

RESULTS

Among 738 patients, 499 went home, and 239 went to IRF. IRF patients were more likely to have increased acute LOS (10.7 vs 3.9 days; t-test, P<0.0001), increased mean NIHSS score (7.8 vs 4.8; t-test, P<0.0001) and higher median mRS score (3 vs 1, t-test, P<0.0001) compared to patients who went home. At 90 days, ischemic stroke patients who received IRF care were more likely to progress to a mRS ≤ 2 (18.7% increase) compared to patients discharged home from acute care (16.3% decrease). Home patients experienced a one-point decrease in mRS at 90 days compared to those who received IRF treatment (median mRS of 3 vs. 2, t-test, P<0.05).

CONCLUSIONS

In ischemic stroke patients, IRF treatment increased the likelihood of achieving mRS ≤ 2 at 90 days indicating the ability to live independently, and decreased the likelihood of mRS decrease, compared with patients discharged directly home after acute stroke care.

Inpatient rehabilitation therapy in stroke patients with reperfusion therapy: a national prospective registry study

BACKGROUND

Little is known about the rate of real-world inpatient rehabilitation therapy (IRT) after stroke. We aimed to determine the rate of inpatient rehabilitation therapy and its associated factors in patients who undergo reperfusion therapy in China.

METHODS

This national prospective registry study included hospitalized ischemic stroke patients aged 14-99 years with reperfusion therapy between January 1, 2019, and June 30, 2020, collecting hospital-level and patient-level demographic and clinical data. IRT included acupuncture or massage, physical therapy, occupational therapy, speech therapy, and others. The primary outcome was the rate of patients receiving IRT.

RESULTS

We included 209,189 eligible patients from 2191 hospitals. The median age was 66 years, and 64.2% were men. Four in five patients received only thrombolysis, and the rest 19.2% underwent endovascular therapy. The overall rate of IRT was 58.2% (95% CI, 58.0-58.5%). Differences in demographic and clinical variables existed between patients with and without IRT. The rates of acupuncture or massage, physical therapy, occupational therapy, speech therapy, and other rehabilitation interventions were 38.0%, 28.8%, 11.8%, 14.4%, and 22.9%, respectively. The rates of single and multimodal interventions were 28.3% and 30.0%, respectively. A lower likelihood of receiving IRT was associated with being 14-50 or 76-99 years old, female, from Northeast China, from Class-C hospitals, receiving only thrombolysis, having severe stroke or severe deterioration, a short length of stay, Covid-19 pandemic and having intracranial or gastrointestinal hemorrhage.

CONCLUSION

Among our patient population, the IRT rate was low with limited use of physical therapy, multimodal interventions, and rehabilitation centers and varied by demographic and clinical features. The implementation of IRT remains a challenge for stroke care, warranting urgent and effective national programs to enhance post-stroke rehabilitation and the adherence to guidelines.

Medicare Advantage Patterns of Poststroke Discharge to an Inpatient Rehabilitation or Skilled Nursing Facility: A Consideration of Demographic, Functional, and Payer Factors

OBJECTIVE

The purpose of this study was to determine the factors influencing the discharge to an inpatient rehabilitation facility (IRF) or a skilled nursing facility (SNF) of people poststroke with Medicare Advantage plans.

METHODS

A retrospective cohort study was conducted with data from naviHealth, a company that manages postacute care discharge placement on behalf of Medicare Advantage organizations. The dependent variable was discharge destination (IRF or SNF). Variables included age, sex, prior living setting, functional status (Activity Measure for Post-Acute Care [AM-PAC]), acute hospital length of stay, comorbidities, and payers (health plans). Analysis estimated relative risk (RR) of discharge to SNF, while controlling for regional variation.

RESULTS

Individuals discharged to an SNF were older (RR = 1.17), women (RR = 1.05), lived at home alone or in assisted living (RR = 1.13 and 1.39, respectively), had comorbidities impacting their function "some" or "severely" (RR = 1.43 and 1.81, respectively), and had a length of stay greater than 5 days (RR = 1.16). Individuals with better AM-PAC Basic Mobility (RR = 0.95) went to an IRF, and individuals with better Daily Activity (RR = 1.01) scores went to an SNF. There was a substantial, significant variation in discharge of individuals to SNF by payer group (RR range = 1.12-1.92).

CONCLUSIONS

The results of this study show that individuals poststroke are more likely to be discharged to an SNF than to an IRF. This study did not find a different discharge decision-making picture for those with Medicare Advantage plans than previously described for other insurance programs.

IMPACT

Medicare Advantage payers have varied patterns in discharge placement to an IRF or SNF for patients poststroke.

A Comparison of Acute Ischemic Stroke Patients Discharged to Inpatient Rehabilitation vs a Skilled Nursing Facility: The Paul Coverdell National Acute Stroke Program

OBJECTIVE

To compare the sociodemographic, clinical, and hospital related factors associated with discharge of acute ischemic stroke (AIS) survivors to inpatient rehabilitation (IRF) and skilled nursing facility (SNF) rehabilitation services.

DESIGN

Retrospective descriptive study from the Paul Coverdell National Acute Stroke Program (PCNASP) participating hospitals during 2016 to 2019.

SETTING

9 Participating states from PCNASP in United States.

PARTICIPANTS

130,988 patients with AIS from 569 hospitals (N=337,857).

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURE

Discharge to IRF and SNF.

RESULTS

Patients discharged to a SNF had longer length of hospital stay, more comorbidities, and higher modified Rankin scores compared with patients discharged to an IRF. Nine characteristics were associated with being less likely to be discharged to an IRF than an SNF: older age (85+ years old, adjusted odds ratio [AOR]=0.20 [confidence interval [CI]=0.18-0.21]), identifying as non-Hispanic Black (AOR=0.85 [CI=0.81-0.89]), identifying as Hispanic (AOR=0.80 [CI=0.74-0.87]), having Medicaid or Medicare (AOR=0.73 [CI=0.70-0.77]), being able to ambulate with assistance from another person (AOR=0.93 [CI=0.89-0.97]), being unable to ambulate (AOR=0.73 [CI=0.62-0.87]) and having comorbidities, prior stroke (AOR=0.69 [CI=0.66-0.73]), diabetes (AOR=0.85 [CI=0.82-0.88]), and myocardial infraction or coronary artery disease (AOR=0.94 [CI=0.90-0.97]). Four characteristics were associated with being more likely to be discharged to an IRF than an SNF: being a man (AOR=1.20 [CI=1.16-1.24]), and having a slight disability (Rankin Score 2) (AOR=1.41 [CI=1.29-1.54]), being at larger hospitals (200-399 beds: AOR=1.31 [CI=1.23-1.40]; 400+ beds: AOR=1.29 [CI=1.20-1.38]), and being at a hospital with stroke unit (AOR=1.12 [CI=1.07-1.17]).

CONCLUSION

This study found differences in demographic, clinical, and hospital characteristics of AIS patients discharged for rehabilitation to an IRF vs SNF. The characteristics of patients receiving rehabilitation services may be helpful for researchers and hospitals making policies related to stroke discharge and practices that optimize patient outcomes. Populations experiencing inequities in access to rehabilitation services should be identified, and those who qualify for rehabilitation in IRF should receive this care in preference to rehabilitation in SNF.

Stroke Rehabilitation and Motor Recovery

OBJECTIVE

Up to 50% of the nearly 800,000 patients who experience a new or recurrent stroke each year in the United States fail to achieve full independence afterward. More effective approaches to enhance motor recovery following stroke are needed. This article reviews the rehabilitative principles and strategies that can be used to maximize post-stroke recovery.

LATEST DEVELOPMENTS

Evidence dictates that mobilization should not begin prior to 24 hours following stroke, but detailed guidelines beyond this are lacking. Specific classes of potentially detrimental medications should be avoided in the early days poststroke. Patients with stroke who are unable to return home should be referred for evaluation to an inpatient rehabilitation facility. Research suggests that a substantial increase in both the dose and intensity of upper and lower extremity exercise is beneficial. A clinical trial supports vagus nerve stimulation as an adjunct to occupational therapy for motor recovery in the upper extremity. The data remain somewhat mixed as to whether robotics, transcranial magnetic stimulation, functional electrical stimulation, and transcranial direct current stimulation are better than dose-matched traditional exercise. No current drug therapy has been proven to augment exercise poststroke to enhance motor recovery.

ESSENTIAL POINTS

Neurologists will collaborate with rehabilitation professionals for several months following a patient's stroke. Many questions still remain about the ideal exercise regimen to maximize motor recovery in patients poststroke. The next several years will likely bring a host of new research studies exploring the latest strategies to enhance motor recovery using poststroke exercise.

Cost Implications of Insurance Associated Disparities in Post-Acute Traumatic Brain and Spinal Cord Injury Rehabilitation

Abstract Post-acute care after spinal cord injury (SCI) or traumatic brain injury (TBI) influences neurological function regained. Inpatient rehabilitation facilities (IRFs) have more intensive care and result in lower mortality and better functional outcomes compared with skilled nursing facilities (SNFs). This study sought to quantify inpatient rehabilitation access by insurance and estimate the cost implications. We conducted a retrospective observational cohort study utilizing 2015-2017 California Office of Statewide Health Planning and Development database of injured adults with SCI and/or TBI. The primary predictor was insurance status. The outcome was discharge destination (home, IRFs, SNFs, long-term acute care [LTAC]) modeled using multi-variable multinomial mixed-effects logistic regression controlling for age, diagnosis, Weighted Elixhauser Comorbidity Index, and New Injury Severity Score. Cost of care for discharge to IRFs versus SNFs was estimated by adjusted quantile regression. Cost simulation predicted the adjusted cost difference if all publicly insured participants were discharged to an IRF. We identified 83,230 patients with an injury mechanism and a primary acute care hospitalization diagnosis of TBI (90.9%), SCI (8.3%), or both (0.8%) who were discharged to an IRF, SNF, LTAC, or home. Publicly insured patients were more likely than privately insured patients to go to SNFs versus IRFs (odds ratio [OR]: 2.17, 95% confidence interval [CI 2.01-2.34]). Sub-group analysis of 6416 participants showed an adjusted median total cost difference of $18,461 (95% CI [$5,908-$38,064]) and adjusted cost-per-day of the post-acute encounter of $1,045 (95% CI [$752-$2,399]) higher for discharge to IRFs versus SNFs. Cost simulation demonstrated an additional adjusted cost of $364M annually for universal IRF access for the publicly insured. Publicly insured SCI and TBI Californians are less frequently discharged to IRFs compared with their privately insured counterparts resulting in a lower short-term cost of care. However, the consequences of decreased intensive rehabilitation utilization in terms of functional recovery and long-term cost implications require further investigation.

Effects of muscle mass and muscle quality estimated by phase angle on functional outcomes in older patients undergoing rehabilitation: A prospective cohort study

BACKGROUND

Both skeletal muscle mass and muscle quality are important predictors of poor prognosis in older patients. However, the effects of muscle mass and muscle quality estimated by the phase angle (PhA) on functional outcomes in older patients undergoing rehabilitation have yet to be reported. This study aimed to investigate whether appendicular skeletal muscle index (SMI) and muscle quality estimated by PhA were independently associated with activities of daily living (ADL) and physical function in older patients undergoing rehabilitation.

METHODS

This prospective cohort study included older patients in a subacute rehabilitation hospital (n = 443). Baseline SMI and PhA were measured using bioelectrical impedance analysis, and low SMI or low PhA were determined using each cutoff value. The primary outcomes were ADL abilities measured using the functional independence measure for motor function (FIM-M) score and physical function measured using the short physical performance battery (SPPB) score at hospital discharge. Association between low SMI and low PhA and FIM-M or SPPB scores at discharge were determined using multiple regression analysis adjusted for confounding factors.

RESULTS

There were significant differences between the normal- and low-PhA groups in the FIM-M and SPPB scores at discharge (P < 0.001). In multiple regression analysis, low PhA was independently associated with FIM-M (β = -0.109, P = 0.013) and SPPB scores (β = 0.535, P < 0.001) at discharge; however, low SMI was not independently associated with these functional outcomes.

CONCLUSION

Decreased muscle quality estimated by the PhA was independently associated with poor ADL abilities and poor physical function in older patients undergoing rehabilitation.

Frequency-tuned electromagnetic field therapy improves post-stroke motor function: A pilot randomized controlled trial

BACKGROUND AND PURPOSE

Impaired upper extremity (UE) motor function is a common disability after ischemic stroke. Exposure to extremely low frequency and low intensity electromagnetic fields (ELF-EMF) in a frequency-specific manner (Electromagnetic Network Targeting Field therapy; ENTF therapy) is a non-invasive method available to a wide range of patients that may enhance neuroplasticity, potentially facilitating motor recovery. This study seeks to quantify the benefit of the ENTF therapy on UE motor function in a subacute ischemic stroke population.

METHODS

In a randomized, sham-controlled, double-blind trial, ischemic stroke patients in the subacute phase with moderately to severely impaired UE function were randomly allocated to active or sham treatment with a novel, non-invasive, brain computer interface-based, extremely low frequency and low intensity ENTF therapy (1-100 Hz, < 1 G). Participants received 40 min of active ENTF or sham treatment 5 days/week for 8 weeks; ~three out of the five treatments were accompanied by 10 min of concurrent physical/occupational therapy. Primary efficacy outcome was improvement on the Fugl-Meyer Assessment - Upper Extremity (FMA-UE) from baseline to end of treatment (8 weeks).

RESULTS

In the per protocol set (13 ENTF and 8 sham participants), mean age was 54.7 years (±15.0), 19% were female, baseline FMA-UE score was 23.7 (±11.0), and median time from stroke onset to first stimulation was 11 days (interquartile range (IQR) 8-15). Greater improvement on the FMA-UE from baseline to week 4 was seen with ENTF compared to sham stimulation, 23.2 ± 14.1 vs. 9.6 ± 9.0, p = 0.007; baseline to week 8 improvement was 31.5 ± 10.7 vs. 23.1 ± 14.1. Similar favorable effects at week 8 were observed for other UE and global disability assessments, including the Action Research Arm Test (Pinch, 13.4 ± 5.6 vs. 5.3 ± 6.5, p = 0.008), Box and Blocks Test (affected hand, 22.5 ± 12.4 vs. 8.5 ± 8.6, p < 0.0001), and modified Rankin Scale (-2.5 ± 0.7 vs. -1.3 ± 0.7, p = 0.0005). No treatment-related adverse events were reported.

CONCLUSIONS

ENTF stimulation in subacute ischemic stroke patients was associated with improved UE motor function and reduced overall disability, and results support its safe use in the indicated population. These results should be confirmed in larger multicenter studies.

Successful Community Discharge Among Older Adults With Traumatic Brain Injury Admitted to Inpatient Rehabilitation Facilities

Objective

To identify admission characteristics that predict a successful community discharge from an inpatient rehabilitation facility (IRF) among older adults with traumatic brain injury (TBI).

Design

In a retrospective cohort study, we leveraged probabilistically linked Medicare Administrative, IRF-Patient Assessment Instrument, and National Trauma Data Bank data to build a parsimonious logistic model to identify characteristics associated with successful discharge. Multiple imputation methods were used to estimate effects across linked datasets to account for potential data linkage errors.

Setting

Inpatient Rehabilitation Facilities in the U.S.

Participants

The sample included a mean of 1060 community-dwelling adults aged 66 years and older across 30 linked datasets (N=1060). All were hospitalized after TBI between 2011 and 2015 and then admitted to an IRF. The mean age of the sample was 79.7 years, and 44.3% of the sample was women.

Interventions

Not applicable.

Main Outcome Measures

Successful discharge home.

Results

Overall, 64.6% of the sample was successfully discharged home. A logistic model including 4 predictor variables: Functional Independence Measure motor (FIM-M) and cognitive (FIM-C) scores, pre-injury chronic conditions, and pre-injury living arrangement, that were significantly associated with successful discharge, resulted in acceptable discrimination (area under the curve: 0.76, 95% confidence interval [CI]: 0.72-0.81). Higher scores on the FIM-M (odds ratio [OR]:1.07, 95% CI: 1.05-1.09) and FIM-C (OR: 1.05, 95% CI: 1.02-1.08) were associated with greater odds of successful discharge, whereas living alone vs with others (OR: 0.46, 95% CI: 0.30-0.71) and a greater number of chronic conditions (OR: 0.94, 95% CI: 0.90-0.99) were associated with lower odds of successful discharge.

Conclusions

The results provide a parsimonious model for predicting successful discharge among older adults admitted to an IRF after a TBI-related hospitalization and provide clinically useful information to inform discharge planning.

Pressure Injury on Poststroke Admission Assessment to Skilled Nursing Facilities: Risk Factors, Management, and Impact on Rehabilitation

OBJECTIVE

To describe pressure injury (PrI) prevalence, comorbidities, and rehabilitation utilization among older adults with stroke at skilled nursing facilities' (SNFs') admission assessment.

DESIGN

Retrospective cohort.

SETTING AND PARTICIPANTS

Older Medicare beneficiaries (>65 years old) with stroke admitted to SNFs.

METHODS

We extracted data between 2013 and 2014 using the Master Beneficiary Summary, Medicare Provider Analysis and Review, and Minimum Data Set 3.0. PI data were assessed during admission assessment.

RESULTS

Of the 65,330 older adults poststroke admitted to SNFs, 11% had at least 1 PrI present on admission assessment. Individuals who were non-Hispanic Black, with a longer hospital stay, from lower socioeconomic status, with higher proportions of comorbidities (eg, underweight, urinary and bowel incontinence, diabetes, congestive heart failure, arrhythmias, and infections), and higher functional impairments were likely to present with a PrI at SNF admission assessment. Compared with individuals with superficial PrI, individuals with deep PrI were more likely to be young-old (<75 years), non-Hispanic Black, from lower socioeconomic status, present with a shorter hospital stay, an intensive care unit stay, with higher functional impairments, skin integrity issues, system failure, and infections. Compared to those without PrI or superficial PrI, individuals with any-stage PrI or deep PrI were more likely to be cotreated by physical and occupational therapist and less likely to receive individual therapy. Those with PrI poststroke had low documented turning and repositioning rates than those without PrI.

CONCLUSIONS AND IMPLICATIONS

Identifying modifiable risk factors to prevent PrIs poststroke in SNFs will facilitate targeted preventative interventions and improve wound care efficacy and rehabilitation utilization for optimized patient outcomes. Identifying residents with a higher risk of PrI during acute care discharge and providing early preventive care during post-acute care would possibly decrease costs and improve outcome quality.

A multicenter study to compare the effectiveness of the inpatient post acute care program versus traditional rehabilitation for stroke survivors

There is insufficient evidence to prove the effect of the Post-acute Care (PAC) program on post-stroke recovery. This study aimed to determine the effectiveness of the PAC versus traditional inpatient rehabilitation (non-PAC) for middle- and old-aged stroke survivors. This multicenter cohort study enrolled 334 stroke patients admitted for post-stroke rehabilitation. The outcome variables included the Barthel Index (BI), Functional Oral Intake Scale (FOIS), Mini Nutritional Assessment-Short Form (MNA-SF), EuroQoL-5D (EQ-5D), Lawton–Brody Instrumental Activities of Daily Living (ADL) Scale, and Mini-Mental State Examination (MMSE). The inverse-probability-of-treatment-weighting method was used to analyze the differences in outcomes between the PAC and non-PAC groups. The PAC group showed better improvements in BI, MNA-SF, EQ-5D, Instrumental ADL, and MMSE compared to the non-PAC group, with differences in effect sizes of 0.54 (95% confidence interval [CI] 0.38–0.71), 0.26 (95% CI 0.10–0.42), 0.50 (95% CI 0.33–0.66), 0.44 (95% CI 0.28–0.60) and 0.34 (95% CI 0.17–0.50), respectively. The PAC project showed more improvement in basic and instrumental ADL and status of swallowing, nutrition, and cognition than those of non-PAC, which had less length of stay restricted by the National Health Insurance. More studies are warranted to investigate the influence of hospital stay and duration from stroke onset on the PAC’s effectiveness.

Readmission to an Acute Care Hospital During Inpatient Rehabilitation After Stroke

OBJECTIVE

The aim of the study was to identify causes for readmission to acute care of patients admitted to inpatient rehabilitation facility after stroke.

DESIGN

The institutional Uniform Data System for Medical Rehabilitation database was used to identify stroke patients who experienced readmission to acute care and an equal number of age-/sex-matched group of patients who successfully completed their inpatient rehabilitation facility stay during 2005-2018. Retrospective chart review was used to extract clinical data. The two study groups were compared using univariate and multivariate analyses.

RESULTS

The rate of readmission to acute care was 4.7% (n = 89; age = 65 ± 14 yrs; 37% female; 65% White; 73% ischemic stroke). The most common indications for transfer were neurological (31%) and cardiovascular (28%). Compared with control group, the readmission to acute care group had statistically higher rates of comorbid conditions, lower median (interquartile range) Functional Independence Measure score on inpatient rehabilitation facility admission (55 [37-65] vs. 64 [51-78], P < 0.001), and a higher rate of sedative/hypnotic prescription (82% vs. 23%, P < 0.001).

CONCLUSIONS

Readmission to acute care is not common in our cohort. Patients who experienced readmission to acute care had higher medical complexity and were prescribed more sedative/hypnotic medications than the control group. Practitioners should be vigilant in patients who meet these criteria.

Physical Medicine and Rehabilitation Consultation for Stroke Patients in Acute Care Setting May Be Associated With an Increased Rate of Discharge to the Community From the Inpatient Rehabilitation Facility

OBJECTIVE

The aim of the study was to determine whether stroke patients who receive physical medicine and rehabilitation consultation in acute care setting are more likely to discharge from inpatient rehabilitation facility to a community setting compared with those who do not.

DESIGN

This was a retrospective analysis of consecutive patients admitted with stroke to inpatient rehabilitation facility between June and October 2018. The primary outcome measure was discharge disposition. Other variables measured included functional independence measures and length of stay. Analysis of baseline covariates was conducted with t tests and analysis of primary outcome measured with Fisher exact test.

RESULTS

We identified 184 consecutive patients, with 62 (33.7%) having and 122 (66.3%) not having a physical medicine and rehabilitation consult; 35 (56.5%) patients versus 51 (41.8%) in physical medicine and rehabilitation consult versus non-physical medicine and rehabilitation group were discharged home (P = 0.042). Between both groups, there were no differences in baseline admission/discharge cognitive or motor functional independence measure scores, total admission/discharge functional independence measure scores, functional independence measure efficiency, or length of stay. However, in both the groups, admission versus discharge overall functional independence measure scores were significantly improved, 71.34 vs. 94.76 and 66.52 vs. 89.94 (P < 0.0001).

CONCLUSIONS

Despite no difference in baseline functional scores or length of stay, physical medicine and rehabilitation consultation of poststroke patients in hospital may be associated with discharge home after inpatient rehabilitation facility.

Emulating Three Clinical Trials that Compare Stroke Rehabilitation at Inpatient Rehabilitation Facilities to Skilled Nursing Facilities

OBJECTIVE

To inform the design of a potential future randomized controlled trial, we emulated three trials where patient-level outcomes were compared following stroke rehabilitation at Inpatient Rehabilitation Facilities (IRFs) to Skilled Nursing Facilities (SNFs).

DESIGN

Trials were emulated using a 1:1 matched propensity score analysis. The three trials differed as facilities from rehabilitation networks with different case-volumes were compared. Rehabilitation network case-volumes were based on the number of stroke patients that each hospital discharged to each specific IRF or SNF. Trial 1 included 60,529 patients from all networks, trial 2 included 34,444 patients from networks with medium- and large case-volumes (i.e., ≥5 patients), trial 3 included 19,161 patients from networks with large case-volumes (i.e., ≥10 patients). E-values were calculated to estimate the minimum strength that an unmeasured confounder would need to be to nullify the results.

SETTING

A national sample of IRFs and SNFs from across the United States.

PARTICIPANTS

Acute Fee-for-service Medicare stroke patients who received IRF or SNF based rehabilitation.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURE(S)

1-year successful community discharge (home for >30 consecutive days) and all-cause mortality.

RESULTS

Overall, 29,500, 15,156, and 7,450 patients were matched for trials 1, 2 and 3. For 1-year successful community discharge, absolute risk differences for IRF patients were 0.21 (95% CI: 0.20, 0.22), 0.17 (95% CI: 0.16, 0.19), and 0.12 (95% CI: 0.10, 0.14) in trials 1, 2 and 3, respectively. For 1-year all-cause mortality, corresponding risk differences were -0.11 (95% CI: -0.12, -0.11), -0.11 (95% CI: -0.12, -0.09), and -0.08 (95% CI: -0.10, -0.06). E-values indicated that a moderately sized unmeasured confounder, with a relative risk of 1.6 to 2.0 would nullify differences in successful community discharge.

CONCLUSION(S)

IRF patients had superior outcomes, but differences were attenuated when IRFs and SNFs from larger rehabilitation networks were compared. The vulnerability of the findings to unmeasured confounding supports the need for an RCT.

Impact of Delirium on Outcomes After Intracerebral Hemorrhage

BACKGROUND AND PURPOSE

Delirium portends worse outcomes after intracerebral hemorrhage (ICH), but it is unclear if symptom resolution or postacute care intensity may mitigate its impact. We aimed to explore differences in outcome associated with delirium resolution before hospital discharge, as well as the potential mediating role of postacute discharge site.

METHODS

We performed a single-center cohort study on consecutive ICH patients over 2 years. Delirium was diagnosed according to DSM-5 criteria and further classified as persistent or resolved based on delirium status at hospital discharge. We determined the impact of delirium on unfavorable 3-month outcome (modified Rankin Scale score, 4-6) using logistic regression models adjusted for established ICH predictors, then used mediation analysis to examine the indirect effect of delirium via postacute discharge site.

RESULTS

Of 590 patients (mean age 70.5±15.5 years, 52% male, 83% White), 59% (n=348) developed delirium during hospitalization. Older age and higher ICH severity were delirium risk factors, but only younger age predicted delirium resolution, which occurred in 75% (161/215) of ICH survivors who had delirium. Delirium was strongly associated with unfavorable outcome, but patients with persistent delirium fared worse (adjusted odds ratio [OR], 7.3 [95% CI, 3.3-16.3]) than those whose delirium resolved (adjusted OR, 3.1 [95% CI, 1.8-5.5]). Patients with delirium were less likely to be discharged to inpatient rehabilitation than skilled nursing facilities (adjusted OR, 0.31 [95% CI, 0.17-0.59]), and postacute care site partially mediated the relationship between delirium and functional outcome in ICH survivors, leading to a 25% reduction in the effect of delirium (without mediator: adjusted OR, 3.0 [95% CI, 1.7-5.6]; with mediator: adjusted OR, 2.3 [95% CI, 1.2-4.3]).

CONCLUSIONS

Acute delirium resolves in most patients with ICH by hospital discharge, which was associated with better outcomes than in patients with persistent delirium. The impact of delirium on outcomes may be further mitigated by postacute rehabilitation.

Association of material deprivation with discharge location and length of stay after inpatient stroke rehabilitation in Ontario: a retrospective, population-based cohort study

BACKGROUND

Low socioeconomic status is associated with increased risk of stroke and worse poststroke functional status. The aim of this study was to determine whether socioeconomic status, as measured by material deprivation, is associated with direct discharge to long-term care or length of stay after inpatient stroke rehabilitation.

METHODS

We performed a retrospective, population-based cohort study of people admitted to inpatient rehabilitation in Ontario, Canada, after stroke. Community-dwelling adults (aged 19-100 yr) discharged from acute care with a most responsible diagnosis of stroke between Sept. 1, 2012, and Aug. 31, 2017, and subsequently admitted to an inpatient rehabilitation bed were included. We used a multivariable logistic regression model to examine the association between material deprivation quintile (from the Ontario Marginalization Index) and discharge to long-term care, and a multivariable negative binomial regression model to examine the association between material deprivation quintile and rehabilitation length of stay.

RESULTS

A total of 18 736 people were included. There was no association between material deprivation and direct discharge to long-term care (most v. least deprived: odds ratio [OR] 1.07, 95% confidence interval [CI] 0.89-1.28); however, people living in the most deprived areas had a mean length of stay 1.7 days longer than that of people in the least deprived areas (p = 0.004). This difference was not significant after adjustment for other baseline differences (relative change in mean 1.02, 95% CI 0.99-1.04).

INTERPRETATION

People admitted to inpatient stroke rehabilitation in Ontario had similar discharge destinations and lengths of stay regardless of their socioeconomic status. In future studies, investigators should consider further examining the associations of material deprivation with upstream factors as well as potential mitigation strategies.

Social Determinants of Health in Physiatry: Challenges and Opportunities for Clinical Decision Making and Improving Treatment Precision

Physiatry is a medical specialty focused on improving functional outcomes in patients with a variety of medical conditions that affect the brain, spinal cord, peripheral nerves, muscles, bones, joints, ligaments, and tendons. Social determinants of health (SDH) play a key role in determining therapeutic process and patient functional outcomes. Big data and precision medicine have been used in other fields and to some extent in physiatry to predict patient outcomes, however many challenges remain. The interplay between SDH and physiatry outcomes is highly variable depending on different phases of care, and more favorable patient profiles in acute care may be less favorable in the outpatient setting. Furthermore, SDH influence which treatments or interventional procedures are accessible to the patient and thus determine outcomes. This opinion paper describes utility of existing datasets in combination with novel data such as movement, gait patterning and patient perceived outcomes could be analyzed with artificial intelligence methods to determine the best treatment plan for individual patients in order to achieve maximal functional capacity.

Functional Status Across Post-Acute Settings is Associated With 30-Day and 90-Day Hospital Readmissions

OBJECTIVE

To examine the association between cocalibrated functional scores across post-acute care settings and the subsequent risk of hospital readmission.

DESIGN

Retrospective cohort study.

SETTING AND PARTICIPANTS

We analyzed 781,021 fee-for-service Medicare beneficiaries discharged to either inpatient rehabilitation facilities (IRFs), skilled nursing facilities (SNFs), or home health agencies (HHA) after an acute hospital stay for stroke (N = 143,277), lower extremity joint replacements (512,577), and hip/femur fracture (125,167) between January 1, 2013, and August 31, 2014.

MEASURES

Functional items from IRF-PAI, MDS, and OASIS were categorized into self-care and mobility domains. We cocalibrated admission functional scores across post-acute settings and divided scores into 4 functional levels using quartiles (Q1-Q4, with Q4 representing the most independent function). The primary outcomes were 30-day and 90-day hospital readmissions (yes/no) after an initial post-acute stay.

RESULTS

Patients who were more dependent in self-care and mobility at the initial post-acute setting were significantly more likely to experience hospital readmission [eg, hazard ratios of 30-day readmission in stroke: 1.54 (95% confidence interval [CI] 1.47-1.61), 1.18 (95% CI 1.14-1.23), and 1.12 (95% CI 1.08-1.16) for Q1, Q2 and Q3, compared to Q4]. We found similar results for risk of 90-day hospital readmission across impairment conditions.

CONCLUSIONS AND IMPLICATIONS

Patients who were more functionally dependent at the initial post-acute setting had a higher risk to readmit to the hospitals after discharging from the post-acute setting for 30 and 90 days, compared with patients who were more functionally independent. This finding is consistent across impairment conditions and post-acute settings. Future research should determine effective strategies of maintaining and facilitating functional performance across post-acute settings to optimize long-term patient outcomes.

Which Road to Recovery?: Factors Influencing Postacute Stroke Discharge Destinations: A Delphi Study

BACKGROUND AND PURPOSE

The criteria for determining the level of postacute care for patients with stroke are variable and inconsistent. The purpose of this study was to identify key factors influencing the selection of postacute level of care for these patients.

METHODS

We used a collaborative 4-round Delphi process to achieve a refined list of factors influencing postacute level of care selection. Our Delphi panel of experts consisted of 32 panelists including physicians, physical therapists, occupational therapists, speech-language pathologists, nurses, stroke survivors, administrators, policy experts, and individuals associated with third-party insurance companies.

RESULTS

In round 1, 207 factors were proposed, with subsequent discussion resulting in consolidation into 15 factors for consideration. In round 2, 15 factors were ranked with consensus on 10 factors; in round 3,10 factors were ranked with consensus on 9 factors. In round 4, the final round, 9 factors were rated with Likert scores ranging from 5 (most important) to 1(not important). The percentage of panelists who provided a rating of 4 or above were as follows: likelihood to benefit from an active rehabilitation program (97%), need for clinicians with specialized rehabilitation skills (94%), need for active and ongoing medical management and monitoring (84%), ability to tolerate an active rehabilitation program (74%), need for caregiver training to return to the community (48%), family/caregiver support (39%), likelihood to return to community/home (39%), ability to return to physical home environment (32%), and premorbid dementia (16%).

CONCLUSIONS

This study provides an expert, consensus-based set of key factors to be considered when determining where stroke patients are discharged for postacute care. These factors may be useful in developing a decision support tool for use in clinical settings.

Intervention Effect of Rapid Rehabilitation Nursing Combined with Continuous Nursing after Discharge on Patients with Cerebral Infarction in Recovery Period and the Changes in Motor Function, Mental State, and Quality of Life

OBJECTIVE

To explore the effect of rapid rehabilitation nursing combined with continuous nursing after discharge on patients with cerebral infarction (CI) in recovery period and its influence on motor function, mental state, and quality of life.

METHODS

From January 2018 to December 2020, 136 patients with CI in recovery period were selected and randomly divided into control group (n = 68) and observation group (n = 68). The control group was given routine nursing, and the observation group was given rapid rehabilitation nursing combined with continuous nursing after discharge. The general clinical data of the two groups were recorded, and the nursing efficiency, modified Barthel index scale (MBI), stroke patients motor assessment scale (MAS), self-rating anxiety and depression scale (SAS and SDS), and quality of life assessment scale (QLI) were compared between the two groups.

RESULTS

The nursing effective rate of the observation group (94.12%, 64/68) was higher than that of the control group (82.35%, 56/68) (P < 0.05). The MBI score, MAS score, and QLI score in the observation group were higher than those in the control group, while the SAS and SDS scores in the observation group were lower than those in the control group (P < 0.05).

CONCLUSION

Rapid rehabilitation nursing combined with continuous nursing after discharge can promote the rapid recovery of patients with CI in recovery period, which can improve the patient's motor function, reduce unhealthy psychology, and improve the quality of life.

Rationale for a Clinical Trial That Compares Acute Stroke Rehabilitation at Inpatient Rehabilitation Facilities to Skilled Nursing Facilities: Challenges and Opportunities

In the United States, approximately 400,000 patients with acute stroke are discharged annually to inpatient rehabilitation facilities (IRFs) or skilled nursing facilities (SNFs). Typically, IRFs provide time-intensive therapy for an average of 2-3 weeks, whereas SNFs provide more moderately intensive therapy for 4-5 weeks. The factors that influence discharge to an IRF or SNF are multifactorial and poorly understood. The complexity of these factors in combination with subjective clinical indications contributes to large variations in the use of IRFs and SNFs. This has significant financial implications for health care expenditure, given that stroke rehabilitation at IRFs costs approximately double that at SNFs. To control health care spending without compromising outcomes, the Institute of Medicine has stated that policy reforms that promote more efficient use of IRFs and SNFs are critically needed. A major barrier to the formulation of such policies is the highly variable and low-quality evidence for the comparative effectiveness of IRF- vs SNF-based stroke rehabilitation. The current evidence is limited by the inability of observational data to control for residual confounding, which contributes to substantial uncertainty around any magnitude of benefit for IRF- vs SNF-based care. Furthermore, it is unclear which specific patients would receive the most benefit from each setting. A randomized controlled trial addresses these issues, because random treatment allocation facilitates an equitable distribution of measured and unmeasured confounders. We discuss several measurement, practical, and ethical issues of a trial and provide our rationale for design suggestions that overcome some of these issues.

Occupational Therapy in Postacute Care for Survivors of COVID-19: Research Gaps We Need to Fill

This column discusses issues in the delivery of postacute care (PAC) rehabilitation services for coronavirus disease 2019 (COVID-19) survivors and gaps in the current research. Occupational therapy practitioners must not only better understand factors that influence the type of PAC rehabilitation a COVID-19 survivor will receive but also comprehend how wide variations in delivery of PAC occupational therapy have affected important outcomes for survivors. The COVID-19 Rehabilitation Research Framework, developed by Cochrane Rehabilitation and the World Health Organization Rehabilitation Program, offers a guide for occupational therapy research priorities that may fill two important gaps: (1) the need for high-quality PAC rehabilitation studies and (2) the need for research on activity and participation assessments and outcomes for COVID-19 survivors. Using electronic health records and other data sources, occupational therapy practitioners and researchers can help build the evidence base to support and guide PAC rehabilitation for survivors of COVID-19 and, perhaps, future pandemics.

The effect of individual nursing on improving the living ability and blood sugar control of Alzheimer disease patients with diabetes mellitus

OBJECTIVE

To explore the effect of individual nursing on Alzheimer disease (AD) patients with diabetes mellitus.

METHODS

A total of 119 patients with AD complicated with diabetes admitted to our hospital from January 2017 to January 2019 were selected for prospective analysis, and 64 patients received individual nursing mode, which were regarded as the personality group (PG). Another 55 patients received routine nursing mode and were regarded as the regular group (RG). The curative effect of AD, blood glucose, living ability, cognitive function, self-care ability and nursing satisfaction of the two groups were investigated.

RESULTS

There was no difference between the two groups in AD curative effect and cognitive function (P > 0.05), and the blood sugar control, living ability, self-care ability and nursing satisfaction of the PG were higher than those of the RG (P < 0.05).

CONCLUSION

Individual nursing can effectively improve the ability of blood sugar control and daily life of AD patients with diabetes mellitus, and greatly enhance the patients' trust, dependence, and satisfaction with medical staff, which is worth popularizing in clinical practice.

Association Between 2010 Medicare Reform and Inpatient Rehabilitation Access in People With Intracerebral Hemorrhage

Background

Evidence suggests intracerebral hemorrhage survivors have earlier recovery compared with ischemic stroke survivors. The Centers for Medicare and Medicaid Services prospective payment system instituted documentation rules for inpatient rehabilitation facilities (IRFs) in 2010, with the goal of optimizing patient selection. We investigated whether these requirements limited IRF and increased skilled nursing facility (SNF) use compared with home discharge.

Methods and Results

Intracerebral hemorrhage discharges to IRF, SNF, or home were estimated using GWTG (Get With The Guidelines) Stroke registry data between January 1, 2008, and December 31, 2015 (n=265 444). Binary hierarchical models determined associations between the 2010 Rule and discharge setting; subgroup analyses evaluated age, geographic region, and hospital type. From January 1, 2008, to December 31, 2009, 45.5% of patients with intracerebral hemorrhage had home discharge, 22.2% went to SNF, and 32.3% went to IRF. After January 1, 2010, there was a 1.06% absolute increase in home discharge, a 0.46% increase in SNF, and a 1.52% decline in IRF. The adjusted odds of IRF versus home discharge decreased 3% after 2010 (adjusted odds ratio [aOR], 0.97; 95% CI, 0.95–1.00). Lower odds of IRF versus home discharge were observed in people aged <65 years (aOR, 0.92; 95% CI, 0.89–0.96), Western states (aOR, 0.89; 95% CI, 0.84–0.95), and nonteaching hospitals (aOR, 0.90; 95% CI, 0.86–0.95). Adjusted odds of SNF versus home discharge increased 14% after 2010 (aOR, 1.14; 95% CI, 1.11–1.18); there were significant associations in all age groups, the Northeast, the South, the Midwest, and teaching hospitals.

Conclusions

The Centers for Medicare and Medicaid Services 2010 IRF prospective payment system Rule resulted in fewer discharges to IRF and more discharges to SNF in patients with intracerebral hemorrhage. Health policy changes potentially affect access to intensive postacute rehabilitation.

Effectiveness of facility-based transition care on health-related outcomes for older adults: A systematic review and meta-analysis

BACKGROUND

Although Transition Care Programmes (TCP) are designed to assist older adults to regain functional ability after hospitalisation, it is unclear whether TCP improve older adults' health-related outcomes.

OBJECTIVES

The objective of the review was to synthesise the best available evidence for the effectiveness of TCP on health-related outcomes for older adults admitted to a transition care facility after hospitalisation.

METHODS

Searches were conducted using the databases PubMed, AMED (Ovid), Embase (Ovid), PscyINFO (Ovid) and CINAHL (Full text) and grey literature from January 2000 to May 2020 in English only. Studies that reported health-related outcomes of older adults (aged 65 and above) who received TCP in a facility setting were deemed eligible for inclusion following critical appraisal by two reviewers. Data were pooled in meta-analysis where possible, or reported narratively.

RESULTS

A total of 21 studies from seven countries [(n = 5 RCT, n = 16 observational cohort studies) participants' mean age 80.2 (±8.3)] were included. Pooled analysis (2069 participants, 7 studies) demonstrated that 80% of older adults undertaking TCP were discharged home [95% CI (0.78-0.82, p < 0.001), I² = 21.99%, very low GRADE evidence]. Proportions of older adults discharged home varied widely between countries (33.3%-86.4%). There was a significant improvement in ability to perform activities of daily living (2001 participants, 7 studies) as measured by the Modified Barthel Index [17.65 points (95% CI 5.68-29.62, p = 0.004), I²  = 0.00%, very low GRADE evidence].

CONCLUSIONS

The proportion of older adults discharged home from TCP compared to other discharge destinations differs between countries. This could be due to the intensity of the rehabilitation delivered and the maximum length of stay allowed prior to discharge.

IMPLICATIONS FOR PRACTICE

Future studies that comprehensively evaluate the efficacy of TCP on health-related outcomes including quality of life are required. Further investigation is required to identify which aspects of TCP affect successful discharge home.

Association Between 2010 Medicare Reforms and Utilization of Postacute Inpatient Rehabilitation in Ischemic Stroke

OBJECTIVE

The aim of the study was to investigate whether the elimination of trial admissions and the initiation of documentation requirements, via the 2010 Centers for Medicare and Medicaid Services Inpatient Rehabilitation Facility Prospective Payment System Rule, limited inpatient rehabilitation facility access while increasing skilled nursing facility utilization compared with home discharge in ischemic stroke patients.

DESIGN

This is a retrospective observational study using Get with the Guidelines - Stroke hospital data between January 1, 2008 and December 31, 2015 (N = 1,643,553).

RESULTS

Between January 1, 2008 and December 31, 2009, 54.1% of patients went home, 25.4% to inpatient rehabilitation facility and 20.5% to skilled nursing facility. Between January 1, 2010 and December 31, 2015, there was a 1.4% absolute increase in home discharge, a 1.1% inpatient rehabilitation facility decline and a 0.3% skilled nursing facility decline.Within the 1.1% absolute decline in inpatient rehabilitation facility discharge, the adjusted odds of inpatient rehabilitation facility versus home discharge decreased 12% after 2010 Rule (adjusted odds ratio = 0.88, 95% confidence interval = 0.87-0.89, P < 0.0001). There was no statistically significant change in skilled nursing facility versus home discharge.Lower adjusted odds of inpatient rehabilitation facility discharge versus home discharge were identical across age groups and were present in all geographic regions.

CONCLUSIONS

In populations with ischemic stroke, the Centers for Medicare and Medicaid Services 2010 Inpatient Rehabilitation Facility Prospective Payment System Rule was associated with a 1.1% absolute decrease in inpatient rehabilitation facility discharge, with a concomitant increase in home discharge rather than to skilled nursing facility.

Skilled Nursing Facilities Modify the Relationship Between Depressive Symptoms and Hospital Readmissions but Not Health Outcomes Among Older Adults

Objectives: Despite detrimental effects of depressive symptoms on self-care and health, hospital discharge practices and the benefits of different discharge settings are poorly understood in the context of depression. Methods: This retrospective cohort study comprised 23,485 hospitalizations from Medicare claims linked to the Health and Retirement Study (2000-2014). Results: Respondents with depressive symptoms were no more likely to be referred to home health, whereas the probability of discharge to skilled nursing facilities (SNFs) went up a half percentage point with each increasing symptom, even after adjusting for family support and health. Rehabilitation in SNFs, compared to routine discharges home, reduced the positive association between depressive symptoms and 30-day hospital readmissions (OR = 0.95, p = 0.029) but did not prevent 30-day falls, 1-year falls, or 1-year mortality associated with depressive symptoms. Discussion: Depressive symptoms were associated with discharges to SNFs, but SNFs do not appear to address depressive symptoms to enhance functioning and survival.

Effect of statewide reduction in extended care facility use after joint replacement on hospital readmission

BACKGROUND

Extended care facility use is a primary driver of variation in hospitalization-associated health care payments and is increasingly a focus for savings under episode-based payment. However, concerns remain that extended care facility limits could incur rising readmissions, emergency department use, or other costs. We analyzed the effects of a statewide value improvement initiative to decrease extended care facility use after lower extremity arthroplasty on extended care facility use, readmission, emergency department use, and payments.

METHODS

We performed a retrospective cohort study using complete claims from the Michigan Value Collaborative for patients undergoing lower extremity joint replacement. We compared the change in extended care facility use before (2012-2013) and after (2016-2017) the aforementioned statewide initiative with 90-day postacute care, readmission, and emergency department rates and payments using t tests.

RESULTS

Of the patients included, 68,537 underwent total knee arthroplasty; 27,131 underwent total hip arthroplasty. Statewide, extended care facility use and postacute care payments decreased (extended care facility: 27.5% before vs 18.1% after, payments: $4,999 vs $3,832, P < .0001) without increased readmission rates (8.0% vs 7.6%, P = .10) or payments ($1,087 vs $1,026, P = .14). Emergency department use increased (7.8% vs 8.9%, P < .0001). Per hospital, there was no association between extended care facility use change and readmission rate change (r = 0.05). Hospital change in extended care facility use ranged from +2.3% (no extended care facility decrease group) to -16.6% (large extended care facility decrease group) and was associated with lower total episode payments without differences in change in readmission rate/payments or emergency department use.

CONCLUSION

Despite decreased use of extended care facilities, there was no compensatory increase in readmission rate or payments. Reducing excess use of extended care facilities after joint replacement may be an important opportunity for savings in episode-based reimbursement.

Changes in the Activity Measure for Post-Acute Care Domains in Persons With Stroke During the First Year After Discharge From Inpatient Rehabilitation

OBJECTIVE

To describe functional changes after inpatient stroke rehabilitation using the Activity Measure for Post-Acute Care (AM-PAC), an assessment measure sensitive to change and with a low risk of ceiling effect.

DESIGN

Retrospective, longitudinal cohort study.

SETTING

Inpatient rehabilitation unit of an urban academic medical center.

PARTICIPANTS

Among 433 patients with stroke admitted from 2012-2016, a total of 269 (62%) were included in our database and 89 of 269 patients (33.1%) discharged from inpatient stroke rehabilitation had complete data. Patients with and without complete data were very similar. The group had a mean age of 68.0±14.2 years, National Institutes of Health Stroke Score of 8.0±8.0, and rehabilitation length of stay of 14.7±7.4 days, with 84% having an ischemic stroke and 22.5% having a recurrent stroke.

INTERVENTION

None.

MAIN OUTCOME MEASURES

Changes in function across the first year after discharge (DC) were measured in a variety of ways. Continuous mean scores for the basic mobility (BM), daily activity (DA), and applied cognitive domains of the AM-PAC were calculated at and compared between inpatient DC and 6 (6M) and 12 months (12M) post DC. Categorical changes among individuals were classified as "improved," "unchanged," or "declined" between the 3 time points based on the minimal detectable change, (estimated) minimal clinically important difference, and a change ≥1 AM-PAC functional stage (FS).

RESULTS

For the continuous analyses, the Friedman test was significant for all domains (P≤.002), with Wilcoxon signed-rank test significant for all domains from DC to 6M (all P<.001) but with no change in BM and DA between 6M and 12M (P>.60) and a decline in applied cognition (P=.002). Despite group improvements from DC to 6M, for categorical changes at an individual level 10%-20% declined and 50%-70% were unchanged. Despite insignificant group differences from 6M-12M, 15%-25% improved and 20%-30% declined in the BM and DA domains.

CONCLUSIONS

Despite group gains from DC to 6M and an apparent "plateau" after 6M post stroke, there was substantial heterogeneity at an individual level. Our results underscore the need to consider individual-level outcomes when evaluating progress or outcomes in stroke rehabilitation.

Association of Therapy Time and Cognitive Recovery in Stroke Patients in Post-Acute Rehabilitation

OBJECTIVES

Cognitive impairment is highly prevalent after stroke, with 77% of people having impairment in at least 2 cognitive domains. The purpose of this study is to describe the association between therapy minutes per length of stay (LOS) day and cognitive recovery in patients receiving rehabilitation services in inpatient post-acute care facilities following a stroke.

DESIGN

Secondary analyses of data collected in inpatient rehabilitation and skilled nursing facilities from 2005 to 2010 for an observational cohort study.

SETTING AND PARTICIPANTS

Participants were adults aged ≥65 years with Medicare insurance and primary diagnosis of stroke (N = 100). Participants who met criteria for dementia (n = 5) were excluded from analyses. We calculated therapy minutes per LOS day for occupational therapy, physical therapy, speech-language pathology, and all therapies combined; therapy times were dichotomized into high or low minutes per LOS day (MLD). We used an ordinary least squares regression model for cognitive outcome at discharge to control for cognitive status at admission, therapy intensity by discipline, and LOS.

RESULTS

At baseline, participants were classified as having severe (n = 11), moderate (n = 39), or mild (n = 45) cognitive impairment. Impairment groups were not significantly different on any demographic variables. The adjusted regression model showed that high occupational therapy MLD (>50 minutes per LOS day) (P = .028) was significantly associated with cognitive measure at discharge compared with low occupational therapy MLD when controlling for cognitive impairment group at baseline (P < .001). Neither high physical therapy MLD nor speech-language pathology MLD was significantly associated with cognitive outcome relative to their respective low TMLD groups.

CONCLUSIONS AND IMPLICATIONS

Our results show that higher-intensity occupational therapy services were associated with better cognitive outcome at discharge from inpatient rehabilitation after stroke. Findings also suggest that volume of therapy alone does not necessarily produce optimal outcomes. Both amount and type of therapy should be tailored to meet the needs of individual patients.
