Functional Status Is Associated With 30-Day Potentially Preventable Hospital Readmissions After Inpatient Rehabilitation Among Aged Medicare Fee-for-Service Beneficiaries

The risk of rehospitalization within 30 days of discharge in older adults with malnutrition: A meta-analysis

INTRODUCTION

Malnutrition is a global health problem associated with higher rehospitalization risk, subsequently increasing the risks of adverse complications, and mortality in older individuals. Nevertheless, studies investigating this are still scarce, and even fewer reviewed and aggregated. A number of studies have recently assessed the correlation of malnourishment with rehospitalization among older adults.

OBJECTIVE/AIM

This systematic review and meta-analysis aimed to elaborate the correlation between malnutrition and 30-day rehospitalization in older adults.

METHODS

Systematic review was conducted on literatures from Cochrane, ScienceDirect, SpringerLink, Oxford Academic, and MEDLINE according to PRISMA Guideline, investigating the correlation of malnutrition in older adults with rehospitalization, using Malnutrition, Older Adults, and Rehospitalization as keywords. Meta-analysis was done using RevMan, with random-effect analysis model. P values of ≤0.05 were considered statistically significant with results reported as risk ratios (RR), mean differences (MD), 95 % confidence intervals (CI) and I2 statistics.

RESULTS

Seven literatures were analysed, consisting of 19,340 patients aged 65 or older undergoing hospitalization. Subjects were assessed with screening tools to identify malnutrition. Malnourished subjects are compared to others with normal nutrition; in cohort studies with follow-up period ranging from 3 to 16 months. Malnutrition significantly increased the risks of rehospitalization within 30 days (RR 1.73 [95 % CI 1.10-2.72], p = 0.02, I2 = 56 %), overall rehospitalization at all times (RR 1.33 [95 % CI 1.16-1.52], p < 0.0001, I2 = 75 %), and overall mortality (RR 2.66 [95 % CI 1.09-6.50], p = 0.03, I2 = 94 %).

CONCLUSION

Malnutrition exhibited significant consequences in older patients regarding the rate of rehospitalization and mortality based on this meta-analysis. Further research is highly encouraged to verify this finding.

Inpatient Rehabilitation Facility Ownership Type Yields Mixed Performances on Quality Measures

OBJECTIVE

To evaluate the effects of inpatient rehabilitation facility (IRF) ownership type on IRF-Quality Reporting Program (IRF-QRP) measures.

DESIGN

Cross-sectional, observational design.

SETTING

We used 2 Centers for Medicare and Medicare publicly-available, facility-level data sources: (1) IRF compare files and (2) IRF rate setting files - final rule. Data from 2021 were included.

PARTICIPANTS

The study sample included 1092 IRFs (N=1092).

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

We estimated the effects of IRF ownership type, defined as for-profit and nonprofit, on 15 IRF-QRP measures using general linear models. Models were adjusted for the following facility-level characteristics: (1) Centers for Medicare and Medicaid census divisions; (2) number of discharges; (3) teaching status; (4) freestanding vs hospital unit; and (5) estimated average weight per discharge.

RESULTS

Ownership type was significantly associated with 9 out of the fifteen IRF-QRP measures. Nonprofit IRFs performed better with having lower readmissions rates within stay and 30-day post discharge. For-profit IRFs performed better for all the functional measures and with higher rates of returning to home and the community. Lastly, for-profit IRFs spent more per Medicare beneficiary.

CONCLUSIONS

Ideally, IRF performance would not vary based on ownership type. However, we found that ownership type is associated with IRF-QRP performance scores. We suggest that future studies investigate how ownership type affects patient-level outcomes and the longitudinal effect of ownership type on IRF-QRP measures.

Potentially Preventable Readmissions After Acute Inpatient Rehabilitation

OBJECTIVE

The aim of the study is to identify causes and risk factors for potentially preventable readmissions of patients discharged from an inpatient rehabilitation facility.

DESIGN

Our hospital billing database was used to identify patients discharged from our inpatient rehabilitation facility between 2013 and 2018 and experienced a potentially preventable readmission within 90 days ( n = 75). Retrospective chart review was completed to obtain clinical data. Of the patients discharged from the inpatient rehabilitation facility who did not experience a potentially preventable readmission, a group of age- and sex-matched controls ( n = 75) was randomly selected. The two study groups were compared using univariate and multivariate analyses.

RESULTS

Our study found that individuals who discharged from acute inpatient rehabilitation were more likely to be readmitted with a potentially preventable readmission if they have a greater number of comorbidities, were admitted initially with a spinal cord injury, or have lower admission or discharge Functional Independence Measure motor scores. The most common potentially preventable readmission diagnoses were sepsis, renal failure, respiratory problems, and urinary tract infection.

CONCLUSIONS

Identifying patients with the common causes for potentially preventable readmissions, in addition to the noted risk factors, is an important consideration for inpatient rehabilitation discharge planning.

All-Cause Readmission or Potentially Avoidable Readmission: Which Is More Predictable Using Frailty, Comorbidities, and ADL?

Background and Objectives

Readmission-related health care reforms have shifted their focus from all-cause readmissions (ACR) to potentially avoidable readmissions (PAR). However, little is known about the utility of analytic tools from administrative data in predicting PAR. This study determined whether 30-day ACR or 30-day PAR is more predictable using tools that assess frailty, comorbidities, and activities of daily living (ADL) from administrative data.

Research Design and Methods

This retrospective cohort study was conducted at a large general acute care hospital in Tokyo, Japan. We analyzed patients aged ≥70 years who had been admitted to and discharged from the subject hospital between July 2016 and February 2021. Using administrative data, we assessed each patient's Hospital Frailty Risk Score, Charlson Comorbidity Index, and Barthel Index on admission. To determine the influence of each tool on readmission predictions, we constructed logistic regression models with different combinations of independent variables for predicting unplanned ACR and PAR within 30 days of discharge.

Results

Among 16 313 study patients, 4.1% experienced 30-day ACR and 1.8% experienced 30-day PAR. The full model (including sex, age, annual household income, frailty, comorbidities, and ADL as independent variables) for 30-day PAR showed better discrimination (C-statistic: 0.79, 95% confidence interval: 0.77-0.82) than the full model for 30-day ACR (0.73, 0.71-0.75). The other prediction models for 30-day PAR also had consistently better discrimination than their corresponding models for 30-day ACR.

Discussion and Implications

PAR is more predictable than ACR when using tools that assess frailty, comorbidities, and ADL from administrative data. Our PAR prediction model may contribute to the accurate identification of at-risk patients in clinical settings who would benefit from transitional care interventions.

The feasibility of remotely monitoring physical, cognitive, and psychosocial function in individuals with stroke or chronic obstructive pulmonary disease

Objective

Clinical implementation of remote monitoring of human function requires an understanding of its feasibility. We evaluated adherence and the resources required to monitor physical, cognitive, and psychosocial function in individuals with either chronic obstructive pulmonary disease or stroke during a three-month period.

Methods

Seventy-three individuals agreed to wear a Fitbit to monitor physical function and to complete monthly online assessments of cognitive and psychosocial function. During a three-month period, we measured adherence to monitoring (1) physical function using average daily wear time, and (2) cognition and psychosocial function using the percentage of assessments completed. We measured the resources needed to promote adherence as (1) the number of participants requiring at least one reminder to synchronize their Fitbit, and (2) the number of reminders needed for each completed cognitive and psychosocial assessment.

Results

After accounting for withdrawals, the average daily wear time was 77.5 ± 19.9% of the day and did not differ significantly between months 1, 2, and 3 (p = 0.30). To achieve this level of adherence, 64.9% of participants required at least one reminder to synchronize their device. Participants completed 61.0% of the cognitive and psychosocial assessments; the portion of assessments completed each month didnot significantly differ (p = 0.44). Participants required 1.13 ± 0.57 reminders for each completed assessment. Results did not differ by disease diagnosis.

Conclusions

Remote monitoring of human function in individuals with either chronic obstructive pulmonary disease or stroke is feasible as demonstrated by high adherence. However, the number of reminders required indicates that careful consideration must be given to the resources available to obtain high adherence.

Patient-Reported Outcome Measures Modestly Enhance Prediction of Readmission in Patients with Cirrhosis

BACKGROUND & AIMS

Patients with cirrhosis have high rates of hospital readmission, but prediction models are suboptimal and have not included important patient-reported outcome measures (PROMs). In a large prospective cohort, we examined the impact of PROMs on prediction of 30-day readmissions.

METHODS

We performed a prospective cohort study of adults with cirrhosis admitted to a tertiary center between June 2014 and March 2020. We collected clinical information, socioeconomic status, and PROMs addressing functional status and quality of life. We used hierarchical competing risk time-to-event analysis to examine the impact of PROMs on readmission prediction.

RESULTS

A total of 654 patients were discharged alive, and 247 (38%) were readmitted within 30 days. Readmission was independently associated with cerebrovascular disease, ascites, prior hospital admission, admission via the emergency department, lower albumin, higher Model for End-Stage Liver Disease, discharge with public transportation, and impaired basic activities of daily living and quality-of-life activity domain. Reduced readmission was associated with cancer, admission for infection, children at home, and impaired emotional function. Compared with a model including only clinical variables, addition of functional status and quality-of-life variables improved the area under the receiver-operating characteristic curve from 0.72 to 0.73 and 0.75, with net reclassification indices of 0.22 and 0.18, respectively. Socioeconomic variables did not significantly improve prediction compared with clinical variables alone. Compared with a model using electronically available variables only, no models improved prediction when examined with integrated discrimination improvement.

CONCLUSIONS

PROMs may marginally add to the prediction of 30-day readmissions for patients with cirrhosis. Poor social support and disability are associated with readmissions and may be high-yield targets for future interventions.

Higher Frequency of Acute Occupational Therapy Services Is Associated With Reduced Hospital Readmissions

IMPORTANCE

Hospital readmissions are associated with poor patient outcomes, including higher risk for mortality, nutritional concerns, deconditioning, and higher costs.

OBJECTIVE

To evaluate how acute occupational therapy service delivery factors affect readmission risk.

DESIGN

Cross-sectional, retrospective study.

SETTING

Single academic medical center.

PARTICIPANTS

Medicare inpatients with a diagnosis included in the Hospital Readmissions Reduction Program (HRRP; N = 17,618). Data were collected from medical records at a large urban hospital in southeastern Wisconsin. Outcomes and Measures: Logistic regression models were estimated to examine the association between acute occupational therapy service delivery factors and odds of readmission. In addition, the types of acute occupational therapy services for readmitted versus not-readmitted patients were compared.

RESULTS

Patients had significantly higher odds of readmission if they received occupational therapy services while hospitalized (odds ratio [OR] = 1.18, 95% confidence interval [CI] [1.07, 1.31]). However, patshients who received acute occupational therapy services had significantly lower odds of readmission if they received a higher frequency (OR = 0.99, 95% CI [0.99,1.00]) of acute occupational therapy services. A significantly higher proportion of patients who were not readmitted, compared with patients who were readmitted, received activities of daily living (ADL) or self-care training (p < .01).

CONCLUSIONS AND RELEVANCE

For patients with HRRP-qualifying diagnoses who received acute occupational therapy services, higher frequency of acute occupational therapy services was linked with lower odds of readmission. Readmitted patients were less likely to have received ADL or self-care training while hospitalized. What This Article Adds: Identifying factors of acute occupational therapy services that reduce the odds of readmission for Medicare patients may help to improve patient outcomes and further define occupational therapy's role in the U.S. quality-focused health care system.

Impact of Acute Self-Care Indicators and Social Factors on Medicare Inpatient Readmission Risk

IMPORTANCE

Readmissions are costly for Medicare and are associated with poor patient outcomes.

OBJECTIVE

To determine whether two domains relevant to acute occupational therapy practice-self-care status and social factors-were associated with readmissions for Medicare patients in the Medicare Hospital Readmissions Reduction Program (HRRP).

DESIGN

Cross-sectional, retrospective study.

SETTING

Single academic medical center.

PARTICIPANTS

Medicare inpatients with a diagnosis included in the HRRP (N = 17,618). Outcomes and Measures: Three logistic regression models were estimated to examine the associations among (1) self-care status and 30-day readmission, (2) social support and 30-day readmission, and (3) housing situation and 30-day readmission. Subgroup analyses were conducted for the individual HRRP diagnoses.

RESULTS

No associations were found between acute self-care status, social support, or housing situation and 30-day readmission when all HRRP diagnoses were examined together. However, higher levels of independence with self-care were significantly associated with reduced odds of readmission for patients with pneumonia.

CONCLUSIONS AND RELEVANCE

The findings for patients with pneumonia are consistent with those of other studies done in the acute care setting. Deficiencies in acute occupational therapy documentation may have affected the findings for the other HRRP diagnoses. What This Article Adds: This study is the first to examine the association between acute self-care status (as documented by acute care occupational therapy practitioners) and readmission.

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.

Thirty-day hospital readmission rate, reasons, and risk factors after acute inpatient cancer rehabilitation

Objectives

To evaluate the 30‐day hospital readmission rate, reasons, and risk factors for patients with cancer who were discharged to home setting after acute inpatient rehabilitation.

Design, Setting, and Participants

This was a secondary retrospective analysis of participants in a completed prospective survey study that assessed the continuity of care and functional safety concerns upon discharge and 30 days after discharge in adults. Patients were enrolled from September 5, 2018, to February 7, 2020, at a large academic quaternary cancer center with National Cancer Institute Comprehensive Cancer Center designation.

Main Outcomes and Measures

Thirty‐day hospital readmission rate, descriptive summary of reasons for readmissions, and statistical analyses of risk factors related to readmission.

Results

Fifty‐five (21%) of the 257 patients were readmitted to hospital within 30 days of discharge from acute inpatient rehabilitation. The reasons for readmissions were infection (20, 7.8%), neoplasm (9, 3.5%), neurological (7, 2.7%), gastrointestinal disorder (6, 2.3%), renal failure (3, 1.1%), acute coronary syndrome (3, 1.1%), heart failure (1, 0.4%), fracture (1, 0.4%), hematuria (1, 0.4%), wound (1, 0.4%), nephrolithiasis (1, 0.4%), hypervolemia (1, 0.4%), and pain (1, 0.4%). Multivariate logistic regression modeling indicated that having a lower locomotion score (OR = 1.29; 95% CI, 1.07–1.56; p = 0.007) at discharge, having an increased number of medications (OR = 1.12; 95% CI, 1.01–1.25; p = 0.028) at discharge, and having a lower hemoglobin at discharge (OR = 1.31; 95% CI, 1.03–1.66; p = 0.031) were independently associated with 30‐day readmission.

Conclusion and Relevance

Among adult patients with cancer discharged to home setting after acute inpatient rehabilitation, the 30‐day readmission rate of 21% was higher than that reported for other rehabilitation populations but within the range reported for patients with cancer who did not undergo acute inpatient rehabilitation.

Research is needed to determine the rates of and risk factors for 30‐day hospital readmission after acute inpatient cancer rehabilitation to understand the nature of this problem and to decrease costs associated with readmissions. Among adult patients with cancer discharged to a home setting after acute inpatient rehabilitation, the 30‐day readmission rate of 21% was higher than that reported for other rehabilitation populations but within the range reported for patients with cancer who did not undergo acute inpatient rehabilitation. Cancer rehabilitation patients may have unique risk factors for readmission.

Mobility and Self-Care are Associated With Discharge to Community After Home Health for People With Dementia

OBJECTIVES

A priority health outcome for patients, families, and the Centers for Medicare & Medicaid Services (CMS) is a patient's ability to return home and remain in the community without adverse events following discharge from post-acute care services. Successful discharge to community (DTC) is defined as being discharged to the community and not experiencing a readmission or death within 30 days of discharge. The objective of this study was to determine the association between patient factors and successful DTC after home health for individuals with Alzheimer's disease and related dementias (ADRD).

DESIGN

This retrospective study derived data from 100% national CMS data files from October 1, 2016, through September 30, 2017.

SETTINGS AND PARTICIPANTS

Criteria from the Home Health Quality Reporting program were used to identify a cohort of 790,439 Medicare home health beneficiaries, 143,164 (18.0%) with ADRD.

MEASURES

Successful DTC rates with associated 95% confidence intervals (CIs) were calculated for each patient characteristic. Multilevel logistic regression was used to estimate the relative risk (RR) of successful DTC after home health, by ADRD diagnosis, mobility, self-care, caregiver support, and medication management, adjusted for patient demographics and clinical characteristics.

RESULTS

Overall, 79.4% of beneficiaries had a successful DTC. Beneficiaries with ADRD had a significantly lower odds of successful DTC than those without ADRD (RR=0.947, 95% CI=0.944-0.950). This association remained significant after adjustment for caregiver support, assistance with medications, independence in mobility, and level of self-care. Greater need for caregiver support, greater need for assistance with medications, greater dependence in mobility, and greater self-care dependence were all associated with decreased risk of successful DTC.

CONCLUSIONS AND IMPLICATIONS

Older adults with ADRD receiving home health had decreased RR of successful DTC. To have a successful DTC, older adults with ADRD need sufficient support from caregivers and independence in functioning.

Association of cognitive impairment severity with potentially avoidable readmissions: A retrospective cohort study of 8897 older patients

INTRODUCTION

Understanding the association between cognitive impairment severity and potentially avoidable readmissions (PARs) in older patients may facilitate the identification of at-risk individuals who would benefit from readmission prevention measures.

METHODS

This retrospective cohort study was conducted using claims data linked with routinely collected cognitive impairment assessment results from a general acute care hospital in Tokyo, Japan. Patients were 65 years or age or older who were discharged from the subject hospital to home or a facility between July 2016 and September 2018.

RESULTS

A multivariable logistic regression analysis adjusted for covariates showed that the odds of PARs within 90 days to the subject hospital for patients with moderate and severe cognitive impairment were 1.418 times (95% confidence interval: 1.005-2.002) and 2.212 times (95% confidence interval: 1.206-4.058) higher, respectively, that for patients with normal cognition.

DISCUSSION

Older inpatients with later-stage cognitive impairment may represent a suitable target population for transitional care programs aimed at reducing readmissions.

Risk factors of readmission after geriatric hospital care: An interRAI-based cohort study in Finland

PURPOSE

To identify risk factors for readmission after geriatric hospital care.

METHODS

A retrospective cohort study of 1,167 community-dwelling patients aged ≥70 years who were hospitalised in two geriatric hospitals and discharged to their homes over a three-year period. We combined the results of the interRAI-post acute care instrument (interRAI-PAC) with hospital discharge records. Factors associated with readmissions within 90 days following discharge were analysed using logistic regression analysis.

RESULTS

The patients' mean age was 84.5 (SD 6.2) years, and 71% (n = 827) were women. The 90-day readmission rate was 29.5%. The risk factors associated with readmission in the univariate analysis were as follows: age, admission from home vs. acute care hospital, Alzheimer's disease, unsteady gait, fatigue, unstable conditions, Activities of Daily Living Hierarchy Scale (ADLH) score, Cognitive Performance Scale (CPS) score, body mass index (BMI), frailty index, bowel incontinence, hearing difficulties, and poor self-rated health. In the multivariable analysis, age of ≥90 years, ADLH ≥1, unsteady gait, BMI <25 or ≥30 kg/m 2 , and frailty remained as risk factors for readmission. Surgical operation during the treatment period was associated with a lower readmission risk.

CONCLUSIONS AND IMPLICATIONS

InterRAI-PAC performed upon admission to geriatric hospitals revealed patient-related risk factors for readmission. Based on the identified risk factors, we recommend that the patient's functional ability, activities of daily living (ADL) needs, and individual factors underlying ADL disability, as well as nutritional and mobility problems should be carefully addressed and managed during hospitalization to diminish the risk for readmission.

Impact of Self-Care and Mobility on One or More Post-Acute Care Transitions

Objective: To investigate the association between functional status and post-acute care (PAC) transition(s). Methods: Secondary analysis of 2013-2014 Medicare data for individuals aged ≥66 years with stroke, lower extremity joint replacements, and hip/femur fracture discharged to one of three PAC settings (inpatient rehabilitation facilities, skilled nursing facilities, and home health agencies). Functional scores were co-calibrated into a 0-100 scale across settings. Multilevel logistic regression was used to test the partition of variance (%) and the probability of PAC transition attributed to the functional score in the initial PAC setting. Results: Patients discharged to inpatient rehabilitation facilities with higher function were less likely to use additional PAC. Function level in an inpatient rehabilitation facility explained more of the variance in PAC transitions than function level while in a skilled nursing facility. Discussion: The function level affected PAC transitions more for those discharged to an inpatient rehabilitation facility than to a skilled nursing facility.

Characteristics of Acute Stroke Patients Readmitted to Inpatient Rehabilitation Facilities: A Cohort Study

BACKGROUND

Reducing acute care readmissions from inpatient rehabilitation facilities (IRFs) is a healthcare reform goal. Stroke patients have higher acute readmission rates and persistent impairments, warranting second IRF hospitalization consideration.

OBJECTIVE

To provide evidence-based information to justify IRF readmission for patients with post-stroke impairments.

MAIN OUTCOME MEASURE

Variables that increase the likelihood of a second IRF hospitalization.

DESIGN

Retrospective cohort study.

SETTING

Seven-center rehabilitation network.

PARTICIPANTS

Stroke patients, readmitted to acute care, who returned or did not return to an in-network IRF between 1 October 2014-31 December 2017(n = 380).

INTERVENTIONS

Univariable analyses (Returned/Did Not Return to IRF) described demographics, stroke type and risk factors. Between group differences in readmission causes, motor impairments and functional independence measure (FIM) scores were examined. Return to IRF logistic regression model included variables with P < .1. Odds ratio and 95% CI were calculated; Relative risk was calculated for categorical variables. P < .05 equaled statistical significance.

RESULTS

One hundred ninety-two stroke patients returned to IRF, 188 did not. Returned to IRF patients were younger (60.6 vs. 66 years; P < .001), sustained hemorrhagic strokes (22.4 vs. 14.2%; P = .01), had lower cardiac disease prevalence (41.7 vs. 55.3%; P = .008) or non-Medicare insurance (59.9 vs. 39.4%; P < .001). Did Not Return to IRF patients had higher admission and discharge motor and total FIM scores. Per point decrease in discharge FIM, second IRF hospitalization odds increased 4% (OR 1.04; 95% CI 1.01-1.07; P = .02). Hemorrhagic stroke patients had 33% increased odds or a 15% higher relative risk of second IRF hospitalization than patients with ischemic stroke [OR 1.33; 95% CI 1.21-1.47; RR 1.15; 95% CI 1.1-1.2; P < .001]. Non-Medicare insurance was associated with 39% increased odds or a 20% higher relative risk of second IRF hospitalization than Medicare [OR 1.39; 95% CI 1.01-1.92; RR 1.2, 95% CI 1.006-1.404; P = .04).

CONCLUSIONS

Hemorrhagic stroke, non-Medicare insurance or lower discharge FIM score during the first IRF hospitalization predict a second IRF stay. Further work is needed to establish the validity of within IRF stay readmission measures.

Variation in Acute Care Rehabilitation and 30-Day Hospital Readmission or Mortality in Adult Patients With Pneumonia

IMPORTANCE

Pneumonia often leads to functional decline during and after hospitalization and is a leading cause of hospital readmissions. Physical and occupational therapists help improve functional mobility and may be of help in this population.

OBJECTIVE

To evaluate whether use of physical and occupational therapy in the acute care hospital is associated with 30-day hospital readmission risk or death.

DESIGN, SETTING, AND PARTICIPANTS

This cohort study included the electronic health records and administrative claims data of 30 746 adults discharged alive with a primary or secondary diagnosis of pneumonia or influenza-related conditions from January 1, 2016, to March 30, 2018. Patients were treated at 12 acute care hospitals in a large health care system in western Pennsylvania. Data for this study were analyzed from September 2019 through March 2020.

EXPOSURES

Number of physical and occupational therapy visits during the acute care stay categorized as none, low (1-3), medium (4-6), or high (>6).

MAIN OUTCOMES AND MEASURES

Outcomes were 30-day hospital readmission or death. Generalized linear mixed models were estimated to examine the association of therapy use and outcomes, controlling for patient demographic and clinical characteristics. Subgroup analyses were conducted for patients older than 65 years, for patients with low functional mobility scores, for patients discharged to the community, and for patients discharged to a post-acute care facility (ie, skilled nursing or inpatient rehabilitation facility).

RESULTS

Of 30 746 patients, 15 507 (50.4%) were men, 26 198 (85.2%) were White individuals, and the mean (SD) age was 67.1 (17.4) years. The 30-day readmission rate was 18.4% (5645 patients), the 30-day death rate was 3.7% (1146 patients), and the rate of either outcome was 19.7% (6066 patients). Relative to no therapy visits, the risk of 30-day readmission or death decreased as therapy visits increased (1-3 visits: odds ratio, 0.98; 95% CI, 0.89-1.08; 4-6 visits: odds ratio, 0.89; 95% CI, 0.79-1.01; >6 visits: odds ratio, 0.86; 95% CI, 0.75-0.98). The association was stronger in the subgroup with low functional mobility and in individuals discharged to a community setting.

CONCLUSIONS AND RELEVANCE

In this study, the number of therapy visits received was inversely associated with the risk of readmission or death. The association was stronger in the subgroups of patients with greater mobility limitations and those discharged to the community.

Enhancing Transitions From Rehabilitation Patient to Wellness Participant for People With Disabilities: An Opportunity for Hospital Community Benefit

Pressure is increasing on not-for-profit hospitals to demonstrate that they provide sufficient benefit to the community to justify their tax-exempt status. Many industry observers have suggested that this community benefit should address unmet medical needs within the community, deficits in the social determinants of health, or health disparities within communities. We argue that one area of clear unmet need is assistance in helping bridge the transition that people with disabilities (PWD) must make from rehabilitation patient to wellness participant. Programs to bridge this transition are necessary because many PWD struggle to identify strategies to maintain and maximize their own well-being after discharge from the healthcare system. As a result, PWD have worse health outcomes than non-disabled individuals. To address these needs, we propose hospitals take a leading role in establishing new, community-based efforts to provide PWD with benefits that will support their effort to self-manage health. Hospitals are well-suited to lead the creation of these programs because of the important role they play in providing services to PWD and because of their ability to bring together multiple stakeholders required to make supportive programs sustainable.

Function and Caregiver Support Associated With Readmissions During Home Health for Individuals With Dementia

OBJECTIVE

The purpose of this study was to determine the association between mobility, self-care, cognition, and caregiver support and 30-day potentially preventable readmissions (PPR) for individuals with dementia.

DESIGN

This retrospective study derived data from 100% national Centers for Medicare and Medicaid Services data files from July 1, 2013, through June 1, 2015.

PARTICIPANTS

Criteria from the Home Health Claims-Based Rehospitalization Measure and the Potentially Preventable 30-Day Post Discharge Readmission Measure for the Home Health Quality Reporting Program were used to identify a cohort of 118,171 Medicare beneficiaries.

MAIN OUTCOME MEASURE

The 30-day PPR rates with associated 95% CIs were calculated for each patient characteristic. Multilevel logistic regression was used to study the relationship between mobility, self-care, caregiver support, and cognition domains and 30-day PPR during home health, adjusting for patient demographics and clinical characteristics.

RESULTS

The overall rate of 30-day PPR was 7.6%. In the fully adjusted models, patients who were most dependent in mobility (odds ratio [OR], 1.59; 95% CI, 1.47-1.71) and self-care (OR, 1.73; 95% CI, 1.61-1.87) had higher odds for 30-day PPR. Patients with unmet caregiving needs had 1.11 (95% CI, 1.05-1.17) higher odds for 30-day PPR than patients whose caregiving needs were met. Patients with cognitive impairment had 1.23 (95% CI, 1.16-1.30) higher odds of readmission than those with minimal to no cognitive impairment.

CONCLUSIONS

Decreased independence in mobility and self-care tasks, unmet caregiver needs, and impaired cognitive processing at admission to home health are associated with risk of 30-day PPR during home health for individuals with dementia. Our findings indicate that deficits in mobility and self-care tasks have the greatest effect on the risk for PPR.

Associations of Hospital Discharge Services With Potentially Avoidable Readmissions Within 30 Days Among Older Adults After Rehabilitation in Acute Care Hospitals in Tokyo, Japan

OBJECTIVE

To examine the associations of 3 major hospital discharge services covered under health insurance (discharge planning, rehabilitation discharge instruction, and coordination with community care) with potentially avoidable readmissions (PARs) within 30 days in older adults after rehabilitation in acute care hospitals in Tokyo, Japan.

DESIGN

Retrospective cohort study using a large-scale medical claims database of all Tokyo residents aged ≥75 years.

SETTING

Acute care hospitals.

PARTICIPANTS

Patients who underwent rehabilitation and were discharged to home (N=31,247; mean age in years ± SD, 84.1±5.7) between October 2013 and July 2014.

INTERVENTIONS

None.

MAIN OUTCOME MEASURE

30-day PAR.

RESULTS

Among the patients, 883 (2.9%) experienced 30-day PAR. A multivariable logistic generalized estimating equation model (with a logit link function and binominal sampling distribution) that adjusted for patient characteristics and clustering within hospitals showed that the discharge services were not significantly associated with 30-day PAR. The odds ratios were 0.962 (95% confidence interval [CI], 0.805-1.151) for discharge planning, 1.060 (95% CI, 0.916-1.227) for rehabilitation discharge instruction, and 1.118 (95% CI, 0.817-1.529) for coordination with community care. In contrast, the odds of 30-day PAR among patients with home medical care services were 1.431 times higher than those of patients without these services (P<.001), and the odds of 30-day PAR among patients with a higher number (median or higher) of rehabilitation units were 2.031 times higher than those of patients with a lower number (below median) (P<.001). Also, the odds of 30-day PAR among patients with a higher Hospital Frailty Risk Score (median or higher) were 1.252 times higher than those of patients with a lower score (below median) (P=.001).

CONCLUSIONS

The insurance-covered discharge services were not associated with 30-day PAR, and the development of comprehensive transitional care programs through the integration of existing discharge services may help to reduce such readmissions.

Functional Status Is Associated With 30-Day Potentially Preventable Readmissions Following Home Health Care

BACKGROUND

Beginning in 2019, home health agencies' rates of potentially preventable hospital readmissions over the 30 days following discharge will be publicly reported.

OBJECTIVES

Our primary objective was to determine the association between patients' functional status at discharge from home health care and 30-day potentially preventable readmissions. A secondary objective was to identify the most common conditions resulting in potentially preventable readmissions.

DESIGN

This was a retrospective cohort study.

PARTICIPANTS

A total of 1,510,297 Medicare fee-for-service beneficiaries discharged from home health care in 2013-2015. Average age was 75.9 (SD, 10.9) years, 60.0% were female, and 84.2% non-Hispanic white.

MEASUREMENTS

Thirty-day potentially preventable readmissions following home health discharge. Functional status measures included mobility, self-care, and impaired cognition.

RESULTS

The overall rate of 30-day potentially preventable readmissions was 2.6% (N=39,452), which accounted for 40% of all 30-day readmissions. After adjusting for sociodemographic and clinical characteristics, the odds ratios for the most dependent score quartile versus the most independent was 1.58 [95% confidence interval (CI), 1.53-1.63] for mobility and 1.65 (95% CI, 1.59-1.69) for self-care. The odds ratios for impaired versus intact cognition was 1.21 (95% CI, 1.18-1.24). The 5 most common conditions resulting in a potentially preventable readmission were congestive heart failure (23.6%), septicemia (16.7%), bacterial pneumonia (9.8%), chronic obstructive pulmonary disease (9.4%), and renal failure (7.5%).

CONCLUSIONS

Functional limitations at discharge from home health are associated with increased risk for potentially preventable readmissions. Future research is needed to determine whether improving functional independence decreases the risk for potentially preventable readmissions following home health care.

Impaired Physical Performance Predicts Hospitalization Risk for Participants in the Program of All-Inclusive Care for the Elderly

BACKGROUND

Medicaid spending on the Program of All-Inclusive Care for the Elderly (PACE) has grown rapidly over the last 5 years. Reducing hospitalization rates is a major goal for PACE. However, there is a paucity of research evaluating the relationship between impaired physical performance and hospitalizations in PACE.

OBJECTIVE

This study tested whether physical therapist-assessed physical performance, measured by the Short Physical Performance Battery (SPPB), can be used to identify participants in PACE at risk for all-cause hospitalizations or potentially avoidable hospitalizations (PAH).

DESIGN

This was a retrospective cohort study of 1093 participants in PACE facilities in the Denver, Colorado, area.

METHODS

Data were acquired from linked electronic medical record data and hospitalization claims. Unadjusted and adjusted Cox proportional hazards regression models were used to evaluate the relationship between SPPB scores and the probabilities of both all-cause hospitalizations and PAH.

RESULTS

The unadjusted likelihood of hospitalization increased with greater physical performance impairment (for SPPB scores ≥8/12: 12.2%; for SPPB scores of 4/12 to 7/12: 15.7%; for SPPB scores <4/12: 21.1%). Compared with participants with SPPB scores ≥8/12, participants with SPPB scores <4/12 had nearly double the unadjusted hazard for hospitalization (hazard ratio = 1.99; 95% CI = 1.34-2.96). In adjusted Cox regression models, participants with SPPB scores <4/12 remained significantly more likely to be hospitalized (hazard ratio = 1.87; 95% CI = 1.24-2.84). Similar relationships were observed for PAH.

LIMITATIONS

The use of data from a single network of PACE facilities might limit generalizability to states with different Medicaid guidelines.

CONCLUSIONS

The findings suggest that impaired physical performance is an independent risk factor for hospitalization among participants in PACE. These findings could help guide the development of PACE program modifications for measuring and intervening on impairments in physical function.
