Abstract
BACKGROUND Stroke survivors with limitations in activities of daily living (ADL) have a greater risk of experiencing falls, hospitalizations, or physical function decline. We examined how informal caregiving received in hours per week by stroke survivors moderated the relationship between ADL limitations and adverse outcomes. METHODS In this retrospective cohort, community-dwelling participants were extracted from the National Health and Aging Trends Study (2011-2020; n=277) and included if they had at least 1 formal or informal caregiver and reported an incident stroke in the prior year. Participants reported the amount of informal caregiving received in the month prior (low [<5.8], moderate [5.8-27.1], and high [27.2-350.4] hours per week) and their number of ADL limitations (ranging from 0 to 7). Participants were surveyed 1 year later to determine the number of adverse outcomes (ie, falls, hospitalizations, and physical function decline) experienced over the year. Poisson regression coefficients were converted to average marginal effects and estimated the moderating effects of informal caregiving hours per week on the relationship between ADL limitations and adverse outcomes. RESULTS Stroke survivors were 69.7% White, 54.5% female, with an average age of 80.5 (SD, 7.6) years and 1.2 adverse outcomes at 2 years after the incident stroke. The relationships between informal caregiving hours and adverse outcomes and between ADL limitations and adverse outcomes were positive. The interaction between informal caregiving hours per week and ADL limitations indicated that those who received the lowest amount of informal caregiving had a rate of 0.12 more adverse outcomes per ADL (average marginal effect, 0.12 [95% CI, 0.005-0.23]; P=0.041) than those who received the highest amounts. CONCLUSIONS Informal caregiving hours moderated the relationship between ADL limitations and adverse outcomes in this sample of community-based stroke survivors. Higher amounts relative to lower amounts of informal caregiving hours per week may be protective by decreasing the rate of adverse outcomes per ADL limitation.

Abstract
OBJECTIVES To examine the association of prestroke continuity of care (COC) with postdischarge health care utilization and expenditures. STUDY POPULATION The study population included 2233 patients with a diagnosis of stroke or a transient ischemic attack hospitalized in one of 41 hospitals in North Carolina between March 2016 and July 2019 and discharged directly home from acute care. METHODS COC was assessed from linked Centers for Medicare and Medicaid Services Medicare claims using the Modified, Modified Continuity Index. Logistic regressions and 2-part models were used to examine the association of prestroke primary care COC with postdischarge health care utilization and expenditures. RESULTS Relative to patients in the first (lowest) COC quartile, patients in the second and third COC quartiles were more likely [21% (95% CI: 8.5%, 33.5%) and 33% (95% CI: 20.5%, 46.1%), respectively] to have an ambulatory care visit within 14 days. Patients in the highest COC quartile were more likely to visit a primary care provider but less likely to see a stroke specialist. Highest as compared with lowest primary care COC quartile was associated with $45 lower (95% CI: $14, $76) average expenditure for ambulatory care visits within 30 days postdischarge. Patients in the highest, as compared with the lowest, primary care COC quartile were 36% less likely (95% CI: 8%, 64%) to be readmitted within 30 days postdischarge and spent $340 less (95% CI: $2, $678) on unplanned readmissions. CONCLUSIONS These findings underscore the importance of primary care COC received before stroke hospitalization to postdischarge care and expenditures.

Referral to Community-Based Rehabilitation Following Acute Stroke: Findings From the COMPASS Pragmatic Trial. Circ Cardiovasc Qual Outcomes 2024; 17:e010026. [PMID: 38189125 PMCID: PMC10997162 DOI: 10.1161/circoutcomes.123.010026] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/01/2023] [Accepted: 10/13/2023] [Indexed: 01/09/2024]
Abstract
BACKGROUND Few studies on care transitions following acute stroke have evaluated whether referral to community-based rehabilitation occurred as part of discharge planning. Our objectives were to describe the extent to which patients discharged home were referred to community-based rehabilitation and identify the patient, hospital, and community-level predictors of referral. METHODS We examined data from 40 North Carolina hospitals that participated in the COMPASS (Comprehensive Post-Acute Stroke Services) cluster-randomized trial. Participants included adults discharged home following stroke or transient ischemic attack (N=10 702). In this observational analysis, COMPASS data were supplemented with hospital-level and county-level data from various sources. The primary outcome was referral to community-based rehabilitation (physical, occupational, or speech therapy) at discharge. Predictor variables included patient (demographic, stroke-related, medical history), hospital (structure, process), and community (therapist supply) measures. We used generalized linear mixed models with a hospital random effect and hierarchical backward model selection procedures to identify predictors of therapy referral. RESULTS Approximately, one-third (36%) of stroke survivors (mean age, 66.8 [SD, 14.0] years; 49% female, 72% White race) were referred to community-based rehabilitation. Rates of referral to physical, occupational, and speech therapists were 31%, 18%, and 10%, respectively. Referral rates by hospital ranged from 3% to 78% with a median of 35%. Patient-level predictors included higher stroke severity, presence of medical comorbidities, and older age. Female sex (odds ratio, 1.24 [95% CI, 1.12-1.38]), non-White race (2.20 [2.01-2.44]), and having Medicare insurance (1.12 [1.02-1.23]) were also predictors of referral. Referral was higher for patients living in counties with greater physical therapist supply. Much of the variation in referral across hospitals remained unexplained. CONCLUSIONS One-third of stroke survivors were referred to community-based rehabilitation. Patient-level factors predominated as predictors. Variation across hospitals was notable and presents an opportunity for further evaluation and possible targets for improved poststroke rehabilitative care.

Implementation of US Post-Acute Care Payment Reform and COVID-19 Policies: Examining Experiences of Health System Leaders, Staff, Patients, and Family Caregivers-A Protocol. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2023; 20:6959. [PMID: 37887697 PMCID: PMC10606322 DOI: 10.3390/ijerph20206959] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/04/2023] [Revised: 10/12/2023] [Accepted: 10/18/2023] [Indexed: 10/28/2023]
Abstract
In fiscal year 2020, new national Medicare payment models were implemented in the two most common post-acute care settings (i.e., skilled nursing facilities (SNFs) and home health agencies (HHAs)), which were followed by the emergence of COVID-19. Given concerns about the unintended consequence of these events, this study protocol will examine how organizations responded to these policies and whether there were changes in SNF and HHA access, care delivery, and outcomes from the perspectives of leadership, staff, patients, and families. We will conduct a two-phase multiple case study guided by the Institute of Medicine's Model of Healthcare Systems. Phase I will include three cases for each setting and a maximum of fifty administrators per case. Phase II will include a subset of Phase I organizations, which are grouped into three setting-specific cases. Each Phase II case will include a maximum of four organizations. Semi-structured interviews will explore the perspectives of frontline staff, patients, and family caregivers (Phase II). Thematic analysis will be used to examine the impact of payment policy and COVID-19 on organizational operations, care delivery, and patient outcomes. The results of this study intend to develop evidence addressing concerns about the unintended consequences of the PAC payment policy during the COVID-19 pandemic.

Postacute Expenditures Among Patients Discharged Home After Stroke or Transient Ischemic Attack: The COMprehensive Post-Acute Stroke Services (COMPASS) Trial. VALUE IN HEALTH : THE JOURNAL OF THE INTERNATIONAL SOCIETY FOR PHARMACOECONOMICS AND OUTCOMES RESEARCH 2023; 26:1453-1460. [PMID: 37422076 DOI: 10.1016/j.jval.2023.06.018] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/09/2022] [Revised: 05/23/2023] [Accepted: 06/14/2023] [Indexed: 07/10/2023]
Abstract
OBJECTIVES The COMPASS (COMprehensive Post-Acute Stroke Services) pragmatic trial cluster-randomized 40 hospitals in North Carolina to the COMPASS transitional care (TC) postacute care intervention or usual care. We estimated the difference in healthcare expenditures postdischarge for patients enrolled in the COMPASS-TC model of care compared with usual care. METHODS We linked data for patients with stroke or transient ischemic attack enrolled in the COMPASS trial with administrative claims from Medicare fee-for-service (n = 2262), Medicaid (n = 341), and a large private insurer (n = 234). The primary outcome was 90-day total expenditures, analyzed separately by payer. Secondary outcomes were total expenditures 30- and 365-days postdischarge and, among Medicare beneficiaries, expenditures by point of service. In addition to intent-to-treat analysis, we conducted a per-protocol analysis to compare Medicare patients who received the intervention with those who did not, using randomization status as an instrumental variable. RESULTS We found no statistically significant difference in total 90-day postacute expenditures between intervention and usual care; the results were consistent across payers. Medicare beneficiaries enrolled in the COMPASS intervention arm had higher 90-day hospital readmission expenditures ($682, 95% CI $60-$1305), 30-day emergency department expenditures ($132, 95% CI $13-$252), and 30-day ambulatory care expenditures ($67, 95% CI $38-$96) compared with usual care. The per-protocol analysis did not yield a significant difference in 90-day postacute care expenditures for Medicare COMPASS patients. CONCLUSIONS The COMPASS-TC model did not significantly change patients' total healthcare expenditures for up to 1 year postdischarge.

Prevalence and Predictors of Ambulatory Care Physicians' Documentation of Mobility Limitations in Older Adults. Arch Phys Med Rehabil 2023; 104:719-727. [PMID: 36731767 PMCID: PMC10164109 DOI: 10.1016/j.apmr.2022.11.018] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/20/2022] [Revised: 11/15/2022] [Accepted: 11/21/2022] [Indexed: 02/03/2023]
Abstract
OBJECTIVE To determine how often physicians document mobility limitations in visits with older adults, and which patient, physician, and practice characteristics associate with documented mobility limitations. DESIGN We completed a cross-sectional analysis of National Ambulatory Medical Care Surveys, years 2012-2016. Multivariate analyses were conducted to identify patient, physician, and practice-level factors associated with mobility limitation documentation. SETTING Ambulatory care visits. PARTICIPANTS We analyzed visits with adults 65 years and older. Final sample size represented 1.3 billion weighted visits. INTERVENTION Not applicable. MAIN OUTCOME MEASURE We defined the presence/absence of a mobility limitation by whether any International Classification of Diseases (ICD)-9 or ICD-10 code related to mobility limitations, injury codes, or the patient's "reasons for visit" were documented in the visits. RESULTS The overall prevalence of mobility limitation documentation was 2.4%. The most common codes were falls-related. Patient-level factors more likely to be associated with mobility limitation documentation were visits by individuals over 85 years of age, relative to 65-69 years, (odds ratio 2.32, 95% confidence interval 1.76-3.07]; with a comorbid diagnosis of arthritis (odds ratio 1.35, 1.18-2.01); and with a comorbid diagnosis of cerebrovascular disease (odds ratio 1.60, 1.13-2.26). Patient-level factors less likely to be associated with mobility limitation documentation were visits by men (odds ratio 0.80, 0.64-0.99); individuals with a cancer diagnosis (odds ratio 0.76, 0.58-0.99); and by individuals seeking care for a chronic problem (relative to a new problem [odds ratio 0.36, 0.29-0.44]). Physician-level factors associated with an increased likelihood of mobility limitation documentation were visits to neurologists (odds ratios 4.48, 2.41-8.32) and orthopedists (odds ratio 2.67, 1.49-4.79) compared with primary care physicians. At the practice-level, mobility documentation varied based on the percentage of practice revenue from Medicare. CONCLUSIONS Mobility limitations are under-documented and may be primarily captured when changes in function are overt.

Abstract
OBJECTIVE The Learning Health Systems Rehabilitation Research Network (LeaRRn), an NIH-funded rehabilitation research resource center, aims to advance the research capacity of learning health systems (LHSs) within the rehabilitation community. A needs assessment survey was administered to inform development of educational resources. METHODS The online survey included 55 items addressing interest in and knowledge of 33 LHS research core competencies in 7 domains and additional items on respondent characteristics. Recruitment targeting rehabilitation researchers and health system collaborators was conducted by LeaRRn, LeaRRn health system partners, rehabilitation professional organizations, and research university program directors using email, listservs, and social media announcements. RESULTS Of the 650 people who initiated the survey, 410 respondents constituted the study sample. Respondents indicated interest in LHS research and responded to at least 1 competency item and/or demographic question. Two-thirds of the study sample had doctoral research degrees, and one-third reported research as their profession. The most common clinical disciplines were physical therapy (38%), communication sciences and disorders (22%), and occupational therapy (10%). Across all 55 competency items, 95% of respondents expressed "a lot" or "some" interest in learning more, but only 19% reported "a lot" of knowledge. Respondents reported "a lot" of interest in a range of topics, including selecting outcome measures that are meaningful to patients (78%) and implementing research evidence in health systems (75%). "None" or "some" knowledge was reported most often in Systems Science areas such as understanding the interrelationships between financing, organization, delivery, and rehabilitation outcomes (93%) and assessing the extent to which research activities will improve the equity of health systems (93%). CONCLUSION Results from this large survey of the rehabilitation research community indicate strong interest in LHS research competencies and opportunities to advance skills and training. IMPACT Competencies where respondents indicated high interest and limited knowledge can inform development of LHS educational content that is most needed.

Abstract
Background:
While several studies have examined care transitions following stroke, few have assessed use of rehabilitation. We explored factors predictive of referral to community-based rehabilitation following stroke.
Setting:
40 NC acute care hospitals that participated in the COMprehensive Post-Acute Stroke Services study from 2016-2019.
Participants:
Adults discharged home following stroke or TIA (N=11,195)
Methods:
Guided by an a priori conceptual framework, 41 predictors of referral to community-based rehabilitation were grouped into 3 patient-level domains: demographics, stroke severity, and medical history (e.g., prior stroke); 2 hospital-level domains: structural characteristics (e.g., bed size) and stroke-specific characteristics (e.g., stroke center status); and 1 community-level domain (county-level therapist supply). We estimated predictors of referral using a logistic mixed model with a hospital-specific random effect. We used a hierarchical backward selection approach, first performing domain-specific model selection, then entering retained variables into a complete model.
Results:
The cohort was 49% female, 72% white, with a mean age of 66.8 (SD=14.0) years and overall low stroke severity [mean [SD] NIHSS 2.4 [3.8]). Thirty-six percent of patients were referred to rehabilitation. Referral varied across hospitals, ranging from 3-78%, with a median of 35%. In the final model, older age, female sex, non-white race, higher stroke severity, longer length of stay, previous stroke, current smoking, and heart failure were associated with higher odds of referral as was hospital-employed vs. external-contracted OT services (Table).
Discussion:
Approximately one-third of stroke survivors discharged home were referred to community-based rehabilitation. Women and non-white patients had higher odds of referral. Hospital and community factors were largely not independent predictors of referral. Unmeasured process measures may play a role in unexplained hospital variation.

Abstract
OBJECTIVE To assess the effectiveness of a hospital physical therapy (PT) referral triggered by scores on a mobility assessment embedded in the electronic health record (EHR) and completed by nursing staff on hospital admission. DATA SOURCES EHR and billing data from 12 acute care hospitals in a western Pennsylvania health system (January 2017-February 2018) and 11 acute care hospitals in a northeastern Ohio health system (August 2019-July 2021). STUDY DESIGN We utilized a regression discontinuity design to compare patients admitted to PA hospitals with stroke who reached the mobility score threshold for an EHR-PT referral (treatment) to those who did not (control). Outcomes were hospital length of stay (LOS) and 30-day readmission or mortality. Control variables included demographics, insurance, income, and comorbidities. Hospital systems with EHR-PT referrals were also compared to those without (OH hospitals as alternative control). Subgroup analyses based on age were also conducted. DATA EXTRACTION We identified adult patients with a primary or secondary diagnosis of stroke and mobility assessments completed by nursing (n = 4859 in PA hospitals, n = 1749 in OH hospitals) who completed their inpatient stay. PRINCIPAL FINDINGS In the PA hospitals, patients with EHR-PT referrals had an 11.4 percentage-point decrease in their 30-day readmission or mortality rates (95% CI -0.57, -0.01) relative to the control. This effect was not observed in the OH hospitals for 30-day readmission (β = 0.01; 95% CI -0.25, 0.26). Adults over 60 years old with EHR-PT referrals in PA had a 26.2 percentage-point (95% CI -0.88, -0.19) decreased risk of readmission or mortality compared to those without. Unclear relationships exist between EHR-PT referrals and hospital LOS in PA. CONCLUSIONS Health systems should consider methodologies to facilitate early acute care hospital PT referrals informed by mobility assessments.

Abstract
BACKGROUND AND OBJECTIVES Informal caregivers of stroke survivors often report the need for training on how to care for a loved one with functional mobility limitations. Evidence on training interventions to help informal caregivers with issues related to mobility is varied. The objective of this scoping review was to examine the literature including skill-based training interventions that educate caregivers on functional mobility for stroke survivors. RESEARCH DESIGN AND METHODS We extracted studies from OVID Medline, Cochrane, ISI Web of Knowledge, and Embase published between 1990 and 2021. At every stage of assessment, data extraction forms were used to reach consensus among at least three out of four authors. We followed PRISMA-ScR guidelines and Arskey and O'Malley's framework to chart information into several tables based on research questions and summarized with descriptive statistics. RESULTS Most studies were conducted outside the US focused on training in mobility and activities of daily living. The stroke survivor, on average, was an older individual (mean age 64.8 [SD = 5.3] years). The informal caregiver was predominately a younger female spouse (mean age 54.2 [SD = 6.3]). More than a third of the studies reported improvement in the stroke survivors' physical function post-intervention, with a mean follow-up time of 4.4 months. Effective studies tended to include stroke survivors with less cognitive and functional mobility limitations at higher training dosages. DISCUSSION AND IMPLICATIONS Gaps in our understanding of informal caregiver training for those caring for stroke survivors are identified, and recommendations are provided for future research.

Abstract
BACKGROUND Stroke patients discharged home often require prolonged assistance from caregivers. Little is known about the real-world effectiveness of a comprehensive stroke transitional care intervention on relieving caregiver strain. OBJECTIVES To describe the effect of the COMPASS transitional care (COMPASS-TC) intervention on caregiver strain and characterize the types, duration, and intensity of caregiving. METHODS The cluster-randomized COMPASS pragmatic trial evaluated the effectiveness of COMPASS-TC versus usual care with patients with mild stroke and TIA at 40 hospitals in North Carolina, USA. Of 5882 patients enrolled, 4208 (71%) identified a familial caregiver. A follow-up Caregiver Questionnaire, including the Modified Caregiver Strain Index, was administered at approximately three months post-discharge. Demographics and frequency, duration, and intensity of caregiving were compared between groups. RESULTS 1228 caregivers (29%) completed the questionnaire. Completion was positively associated with older patient age, white race, and spousal relationship. One-third of the caregivers provided ≥30 hours of care per week and 889 (79%) provided care ≥9 weeks. Average standardized caregiver strain was 21.9 (0-100), increasing with stroke severity and comorbidity burden. Women caregivers reported higher strain than men. Treatment allocation was not associated with caregiver strain. CONCLUSIONS This sample of mild stroke and TIA survivors received significant assistance from familial caregivers. However, caregiver strain was relatively low. Findings support the importance of familial caregiving in stroke, the continued disproportionate burden on women within the family, and the need for future research on caregiver support.

Hospital Readmissions and Mortality Among Fee-for-Service Medicare Patients With Minor Stroke or Transient Ischemic Attack: Findings From the COMPASS Cluster-Randomized Pragmatic Trial. J Am Heart Assoc 2021; 10:e023394.

Abstract
Background Mortality and hospital readmission rates may reflect the quality of acute and postacute stroke care. Our aim was to investigate if, compared with usual care (UC), the COMPASS-TC (Comprehensive Post-Acute Stroke Services Transitional Care) intervention (INV) resulted in lower all-cause and stroke-specific readmissions and mortality among patients with minor stroke and transient ischemic attack discharged from 40 diverse North Carolina hospitals from 2016 to 2018. Methods and Results Using Medicare fee-for-service claims linked with COMPASS cluster-randomized trial data, we performed intention-to-treat analyses for 30-day, 90-day, and 1-year unplanned all-cause and stroke-specific readmissions and all-cause mortality between INV and UC groups, with 90-day unplanned all-cause readmissions as the primary outcome. Effect estimates were determined via mixed logistic or Cox proportional hazards regression models adjusted for age, sex, race, stroke severity, stroke diagnosis, and documented history of stroke. The final analysis cohort included 1069 INV and 1193 UC patients (median age 74 years, 80% White, 52% women, 40% with transient ischemic attack) with median length of hospital stay of 2 days. The risk of unplanned all-cause readmission was similar between INV versus UC at 30 (9.9% versus 8.7%) and 90 days (19.9% versus 18.9%), respectively. No significant differences between randomization groups were seen in 1-year all-cause readmissions, stroke-specific readmissions, or mortality. Conclusions In this pragmatic trial of patients with complex minor stroke/transient ischemic attack, there was no difference in the risk of readmission or mortality with COMPASS-TC relative to UC. Our study could not conclusively determine the reason for the lack of effectiveness of the INV. Registration URL: https://www.clinicaltrials.gov; Unique identifier: NCT02588664.

Skilled Nursing and Inpatient Rehabilitation Facility Use by Medicare Fee-for-Service Beneficiaries s Discharged Home following a Stroke: Findings from the COMPASS Trial. Arch Phys Med Rehabil 2021; 103:882-890.e2. [PMID: 34740596 DOI: 10.1016/j.apmr.2021.10.015] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/19/2021] [Revised: 09/29/2021] [Accepted: 10/06/2021] [Indexed: 11/02/2022]
Abstract
OBJECTIVES To examine the effect of a comprehensive transitional care model on the utilization of skilled nursing facility (SNF) and inpatient rehabilitation facility (IRF) care in the 12 months after acute care discharge home following stroke; and to identify predictors of experiencing a SNF or IRF admission following discharge home after stroke. DESIGN Cluster randomized pragmatic trial Setting: 41 acute care hospitals in North Carolina. PARTICIPANTS 2,262 Medicare fee-for-service beneficiaries with transient ischemic attack or stroke discharged home. The sample was 80.3% White and 52.1% female, with a mean (standard deviation [SD]) age of 74.9 (10.2) years and a mean (SD) NIH stroke scale score of 2.3 (3.7). INTERVENTION Comprehensive transitional care model (COMPASS-TC) which consisted of a 2-day follow-up phone call from the post-acute care coordinator (PAC) and 14-day in-person visit with the PAC and advanced practice provider. MAIN OUTCOME MEASURES Time to first SNF or IRF and SNF or IRF admission (yes/no) in the 12 months following discharge home. All analyses utilized multivariable mixed models including a hospital-specific random effect to account for the non-independence of measures within hospital. Intent to treat analyses using Cox proportional hazards regression assessed the effect of COMPASS-TC on time to SNF/IRF admission. Logistic regression was used to identify clinical and non-clinical predictors of SNF/IRF admission. RESULTS Only 34% of patients in the intervention arm received COMPASS-TC per protocol. COMPASS-TC was not associated with a reduced hazard of a SNF/ IRF admission in the 12 months post-discharge (HR=1.20 [0.95 - 1.52]) compared to usual care. This estimate was robust to additional covariate adjustment (HR=1.23 [0.93-1.64]). Both clinical and non-clinical factors (i.e., insurance, geography) were predictors of SNF/IRF use. CONCLUSIONS COMPASS-TC was not consistently incorporated into real-world clinical practice. The use of a comprehensive transitional care model for patients discharged home after stroke was not associated with SNF or IRF admissions in a 12-month follow-up period. Non-clinical factors predictive of SNF/IRF use suggest potential issues with access to this type of care.

Abstract
Background Readmissions in patients with congestive heart failure are common and often preventable. Limited data suggest that patients discharged to a less intensive postacute care setting than recommended are likely to readmit. We examined whether postacute setting discordance (discharge to a less intensive postacute setting than recommended by a physical and occupational therapist) was associated with hospital readmission in patients with congestive heart failure. We also assessed sociodemographic and clinical predictors of setting discordance. Methods and Results Retrospective analysis of administrative claims and electronic health record data was conducted on 25 500 adults with a discharge diagnosis of congestive heart failure from 12 acute care hospitals in Western Pennsylvania. Generalized linear mixed models were estimated to examine the association between postacute setting discordance and 30‐day hospital readmission and to identify predictors of setting discordance. The 30‐day readmission and postacute setting discordance rates were high (23.7%, 20.6%). While controlling for demographic and clinical covariates, patients in discordant postacute settings were more likely to be readmitted within 30 days (adjusted odds ratio [OR], 1.12; 95% CI, 1.04–1.20). The effect was also seen in the subgroup of patients with low mobility scores (adjusted OR, 1.20; 95% CI, 1.08–1.33). Factors associated with setting discordance were lower‐income, higher comorbidity burden, therapist recommendation disagreement, and midrange mobility limitations. Conclusions Postacute setting discordance was associated with an increased readmission risk in patients hospitalized with congestive heart failure. Maximizing concordance between therapist recommended and actual postacute discharge setting may decrease readmissions. Understanding factors associated with post‐acute setting discordance can inform strategies to improve the quality of the discharge process.

Association Between Use of Rehabilitation in the Acute Care Hospital and Hospital Readmission or Mortality in Patients With Stroke. Arch Phys Med Rehabil 2021; 102:1700-1707.e4. [PMID: 33819490 DOI: 10.1016/j.apmr.2021.02.026] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/19/2020] [Revised: 02/15/2021] [Accepted: 02/16/2021] [Indexed: 11/17/2022]
Abstract
OBJECTIVE To examine the association between the number of physical and occupational therapist visits received in the acute care hospital and the risk of hospital readmission or death. DESIGN Retrospective cohort study of electronic health records and administrative claims data collected for 2.25 years (January 1, 2016-March 30, 2018). SETTING Twelve acute care hospitals in a large health care system in western Pennsylvania. PARTICIPANTS Adults (N=8279) discharged with a primary stroke diagnosis. INTERVENTIONS The exposure was number of physical and occupational therapist visits during the acute care stay. MAIN OUTCOME MEASURES Generalized linear mixed models were estimated to examine the relationship between therapy use and 30- and 7-day hospital readmission or death (outcome), controlling for patient demographic and clinical characteristics. RESULTS The 30- and 7-day readmission or death rates were 16.0% and 5.7%, respectively. The number of therapist visits was inversely related to the risk of 30-day readmission or death. Relative to no therapist visits, the odds of readmission or death were 0.70 (95% confidence interval [CI], 0.54-0.90) for individuals who received 1-2 visits, 0.59 (95% CI, 0.43-0.81) for 3-5 visits, and 0.57 (95% CI, 0.39-0.81) for >5 visits. A similar pattern was seen for the 7-day outcome, with slightly larger effect sizes. Effects were also greater in individuals with more mobility limitations on admission and for those discharged to a postacute care facility vs home. CONCLUSIONS There was an inverse relationship between the number of therapist visits and risk for readmission or death for patients with stroke discharged from an acute care hospital. Effects differed by time to the event (30d vs 7d), discharge location, and mobility limitations on admission.

Hospital to Home Transition for Patients With Stroke Under Bundled Payments. Arch Phys Med Rehabil 2021; 102:1658-1664. [PMID: 33811853 PMCID: PMC10152978 DOI: 10.1016/j.apmr.2021.03.010] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/29/2020] [Revised: 02/19/2021] [Accepted: 03/02/2021] [Indexed: 11/29/2022]
Abstract
Bundled payments are a promising alternative payment model for reducing costs and improving the coordination of postacute stroke care, yet there is limited evidence supporting the effectiveness of bundled payments for stroke. This may be due to the lack of effective strategies to address the complex needs of stroke survivors. In this article, we describe COMprehensive Post-Acute Stroke Services (COMPASS), a comprehensive transitional care intervention focused on discharge from the acute care setting to home. COMPASS may serve as a potential care redesign strategy under bundled payments for stroke, such as the Centers for Medicare & Medicaid Innovation Bundled Payment for Care Improvement Initiative. The COMPASS care model is aligned with the incentive structures and essential components of bundled payments in terms of care coordination, patient assessment, patient and family involvement, and continuity of care. Ongoing evaluation will inform the design of incorporating COMPASS-like transitional care interventions into a stroke bundle.

Stratified care to prevent chronic low back pain in high-risk patients: The TARGET trial. A multi-site pragmatic cluster randomized trial. EClinicalMedicine 2021; 34:100795. [PMID: 33870150 PMCID: PMC8040279 DOI: 10.1016/j.eclinm.2021.100795] [Citation(s) in RCA: 37] [Impact Index Per Article: 12.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/20/2020] [Revised: 02/22/2021] [Accepted: 02/24/2021] [Indexed: 12/21/2022] Open
Abstract
BACKGROUND Many patients with acute low back pain (LBP) first seek care from primary care physicians. Evidence is lacking for interventions to prevent transition to chronic LBP in this setting. We aimed to test if implementation of a risk-stratified approach to care would result in lower rates of chronic LBP and improved self-reported disability. METHODS We conducted a pragmatic, cluster randomized trial using 77 primary care clinics in four health care systems across the United States. Practices were randomly assigned to a stratified approach to care (intervention) or usual care (control). Using the STarTBack screening tool, adults with acute LBP were screened low, medium, and high-risk. Patients screened as high-risk were eligible. The intervention included electronic best practice alerts triggering referrals for psychologically informed physical therapy (PIPT). PIPT education was targeted to community clinics geographically close to intervention primary care clinics. Primary outcomes were transition to chronic LBP and self-reported disability at six months. Trial Registry: ClinicalTrials.gov NCT02647658. FINDINGS Between May 2016 and June 2018, 1207 patients from 38 intervention and 1093 from 37 control practices were followed. In the intervention arm, around 50% of patients were referred for physical therapy (36% for PIPT) compared to 30% in the control. At 6 months, 47% of patients reported transition to chronic LBP in the intervention arm (38 practices, n = 658) versus 51% of patients in the control arm (35 practices, n = 635; OR=0.83 95% CI 0.64, 1.09; p = 0.18). No differences in disability were detected (difference -2·1, 95% CI -4.9-0.6; p = 0.12). Opioids and imaging were prescribed in 22%-25% and 23%-26% of initial visits, for intervention and control, respectively. Twelve-month LBP utilization was similar in the two groups. INTERPRETATION There were no differences detected in transition to chronic LBP among patients presenting with acute LBP using a stratified approach to care. Opioid and imaging prescribing rates were non-concordant with clinical guidelines. FUNDING Patient-Centered Outcomes Research Institute (PCORI) contract # PCS-1402-10867.

Abstract
BACKGROUND The COMprehensive Post-Acute Stroke Services (COMPASS) model, a transitional care intervention for stroke patients discharged home, was tested against status quo postacute stroke care in a cluster-randomized trial in 40 hospitals in North Carolina. This study examined the hospital-level costs associated with implementing and sustaining COMPASS. METHODS Using an activity-based costing survey, we estimated hospital-level resource costs spent on COMPASS-related activities during approximately 1 year. We identified hospitals that were actively engaged in COMPASS during the year before the survey and collected resource cost estimates from 22 hospitals. We used median wage data from the Bureau of Labor Statistics and COMPASS enrollment data to estimate the hospital-level costs per COMPASS enrollee. RESULTS Between November 2017 and March 2019, 1582 patients received the COMPASS intervention across the 22 hospitals included in this analysis. Average annual hospital-level COMPASS costs were $2861 per patient (25th percentile: $735; 75th percentile: $3,475). Having 10% higher stroke patient volume was associated with 5.1% lower COMPASS costs per patient (P=0.016). About half (N=10) of hospitals reported postacute clinic visits as their highest-cost activity, while a third (N=7) reported case ascertainment (ie, identifying eligible patients) as their highest-cost activity. CONCLUSIONS We found that the costs of implementing COMPASS varied across hospitals. On average, hospitals with higher stroke volume and higher enrollment reported lower costs per patient. Based on average costs of COMPASS and readmissions for stroke patients, COMPASS could lower net costs if the model is able to prevent about 6 readmissions per year.

Abstract
IMPORTANCE Acute low back pain (LBP) is highly prevalent, with a presumed favorable prognosis; however, once chronic, LBP becomes a disabling and expensive condition. Acute to chronic LBP transition rates vary widely owing to absence of standardized operational definitions, and it is unknown whether a standardized prognostic tool (ie, Subgroups for Targeted Treatment Back tool [SBT]) can estimate this transition or whether early non-guideline concordant treatment is associated with the transition to chronic LBP. OBJECTIVE To assess the associations between the transition from acute to chronic LBP with SBT risk strata; demographic, clinical, and practice characteristics; and guideline nonconcordant processes of care. DESIGN, SETTING, AND PARTICIPANTS This inception cohort study was conducted alongside a multisite, pragmatic cluster randomized trial. Adult patients with acute LBP stratified by SBT risk were enrolled in 77 primary care practices in 4 regions across the United States between May 2016 and June 2018 and followed up for 6 months, with final follow-up completed by March 2019. Data analysis was conducted from January to March 2020. EXPOSURES SBT risk strata and early LBP guideline nonconcordant processes of care (eg, receipt of opioids, imaging, and subspecialty referral). MAIN OUTCOMES AND MEASURES Transition from acute to chronic LBP at 6 months using the National Institutes of Health Task Force on Research Standards consensus definition of chronic LBP. Patient demographic characteristics, clinical factors, and LBP process of care were obtained via electronic medical records. RESULTS Overall, 5233 patients with acute LBP (3029 [58%] women; 4353 [83%] White individuals; mean [SD] age 50.6 [16.9] years; 1788 [34%] low risk; 2152 [41%] medium risk; and 1293 [25%] high risk) were included. Overall transition rate to chronic LBP at six months was 32% (1666 patients). In a multivariable model, SBT risk stratum was positively associated with transition to chronic LBP (eg, high-risk vs low-risk groups: adjusted odds ratio [aOR], 2.45; 95% CI, 2.00-2.98; P < .001). Patient and clinical characteristics associated with transition to chronic LBP included obesity (aOR, 1.52; 95% CI, 1.28-1.80; P < .001); smoking (aOR, 1.56; 95% CI, 1.29-1.89; P < .001); severe and very severe baseline disability (aOR, 1.82; 95% CI, 1.48-2.24; P < .001 and aOR, 2.08; 95% CI, 1.60-2.68; P < .001, respectively) and diagnosed depression/anxiety (aOR, 1.66; 95% CI, 1.28-2.15; P < .001). After controlling for all other variables, patients exposed to 1, 2, or 3 nonconcordant processes of care within the first 21 days were 1.39 (95% CI, 1.21-2.32), 1.88 (95% CI, 1.53-2.32), and 2.16 (95% CI, 1.10-4.25) times more likely to develop chronic LBP compared with those with no exposure (P < .001). CONCLUSIONS AND RELEVANCE In this cohort study, the transition rate to chronic LBP was substantial and increased correspondingly with SBT stratum and early exposure to guideline nonconcordant care.

Movement Matters, and So Does Context: Lessons Learned From Multisite Implementation of the Movement Matters Activity Program for Stroke in the Comprehensive Postacute Stroke Services Study. Arch Phys Med Rehabil 2020; 102:532-542. [PMID: 33263286 DOI: 10.1016/j.apmr.2020.09.386] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/24/2020] [Revised: 09/06/2020] [Accepted: 09/08/2020] [Indexed: 11/16/2022]
Abstract
The purpose of this Special Communication is to discuss the rationale and design of the Movement Matters Activity Program for Stroke (MMAP) and explore implementation successes and challenges in home health and outpatient therapy practices across the stroke belt state of North Carolina. MMAP is an interventional component of the Comprehensive Postacute Stroke Services Study, a randomized multicenter pragmatic trial of stroke transitional care. MMAP was designed to maximize survivor health, recovery, and functional independence in the community and to promote evidence-based rehabilitative care. MMAP provided training, tools, and resources to enable rehabilitation providers to (1) prescribe physical activity and exercise according to evidence-based guidelines and programs, (2) match service setting and parameters with survivor function and benefit coverage, and (3) align treatment with quality metric reporting to demonstrate value-based care. MMAP implementation strategies were aligned with the Expert Recommendations for Implementing Change project, and MMAP site champion and facilitator survey feedback were thematically organized into the Consolidated Framework for Implementation Research domains. MMAP implementation was challenging, required modification and was affected by provider- and system-level factors. Program and study participation were limited and affected by practice priorities, productivity standards, and stroke patient volume. Sites with successful implementation appeared to have empowered MMAP champions in vertically integrated systems that embraced innovation. Findings from this broad evaluation can serve as a road map for the design and implementation of other comprehensive, complex interventions that aim to bridge the currently disconnected realms of acute care, postacute care, and community resources.

Abstract
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.

Time Between an Emergency Department Visit and Initiation of Physical Therapist Intervention: Health Care Utilization and Costs. Phys Ther 2020; 100:1782-1792. [PMID: 32478851 PMCID: PMC7530572 DOI: 10.1093/ptj/pzaa100] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/21/2019] [Accepted: 05/26/2020] [Indexed: 01/19/2023]
Abstract
OBJECTIVE The aim of this study was to examine the association between the length of time between an emergency department (ED) visit and the subsequent initiation of physical therapist intervention for low back pain (LBP) on 1-year LBP-related health care utilization (ie, surgery, advanced imaging, injections, long-term opioid use, ED visits) and costs. METHODS This retrospective cohort study focused on individuals who consulted the ED for an initial visit for LBP. Claims from a single statewide, all-payers database were used. LBP-related health care use and costs for the 12 months after the ED visit were extracted. Poisson and general linear models weighted with inverse probability treatment weights were used to compare the outcomes of patients who attended physical therapy early or delayed after the ED visit. RESULTS Compared with the delayed physical therapy group (n = 94), the early physical therapy group (n = 171) had a lower risk of receiving lumbar surgery (relative risk [RR] = 0.47, 95% CI = 0.26-0.86) and advanced imaging (RR = 0.72, 95% CI = 0.55-0.95), and they were less likely to have long-term opioid use (RR = 0.45, 95% CI = 0.28-0.76). The early physical therapy group incurred lower costs (mean = $3,806, 95% CI = $1,998-$4,184) than those in the delayed physical therapy group (mean = $8,689, 95% CI = $4,653-$12,727). CONCLUSION Early physical therapy following an ED visit was associated with a reduced risk of using some types of health care and reduced health care costs in the 12 months following the ED visit. IMPACT STATEMENT The ED is an entry point into the health care system for patients with LBP. Until now, the impact of the length of time between an ED visit and physical therapy for LBP has not been well understood. This study shows that swift initiation of physical therapy following an ED visit for LBP is associated with lower LBP-related health utilization for some important outcomes and lower LBP-related health care costs.

Abstract
Background The objectives of this study were to develop and test in real-world clinical practice the effectiveness of a comprehensive postacute stroke transitional care (TC) management program. Methods and Results The COMPASS study (Comprehensive Post-Acute Stroke Services) was a pragmatic cluster-randomized trial where the hospital was the unit of randomization. The intervention (COMPASS-TC) was initiated at 20 hospitals, and 20 hospitals provided their usual care. Hospital staff enrolled 6024 adult stroke and transient ischemic attack patients discharged home between 2016 and 2018. COMPASS-TC was patient-centered and assessed social and functional determinates of health to inform individualized care plans. Ninety-day outcomes were evaluated by blinded telephone interviewers. The primary outcome was functional status (Stroke Impact Scale-16); secondary outcomes were mortality, disability, medication adherence, depression, cognition, self-rated health, fatigue, care satisfaction, home blood pressure monitoring, and falls. The primary analysis was intention to treat. Of intervention hospitals, 58% had uninterrupted intervention delivery. Thirty-five percent of patients at intervention hospitals attended a COMPASS clinic visit. The primary outcome was measured for 59% of patients and was not significantly influenced by the intervention. Mean Stroke Impact Scale-16 (±SD) was 80.6±21.1 in TC versus 79.9±21.4 in usual care. Home blood pressure monitoring was self-reported by 72% of intervention patients versus 64% of usual care patients (adjusted odds ratio, 1.43 [95% CI, 1.21-1.70]). No other secondary outcomes differed. Conclusions Although designed according to the best available evidence with input from various stakeholders and consistent with Centers for Medicare and Medicaid Services TC policies, the COMPASS model of TC was not consistently incorporated into real-world health care. We found no significant effect of the intervention on functional status at 90 days post-discharge. Registration URL: https://www.clinicaltrials.gov; Unique identifier: NCT02588664.

Abstract
OBJECTIVE To determine the rate of physical therapy (PT) referral and patient and physician characteristics associated with PT referral for benign paroxysmal positional vertigo (BPPV) and other peripheral vestibular disorders (PVD) in ambulatory care clinics in the United States. DESIGN Cross-sectional analysis of the National Ambulatory Medical Care Survey 2004-2015 SETTING: Ambulatory care clinics in the United States. PARTICIPANTS We identified 5.6 million weighted adult visits for BPPV (International Classification of Diseases-9th Revision-Clinical Modifications (ICD-9-CM): 386.11) and 6.6 million weighted visits for other PVDs (ICD-9-CM: 386.1-386.9, excluding 386.11 and 386.2) made by patients 18 years and older from 2004 through 2015. INTERVENTIONS Not applicable. MAIN OUTCOME MEASURES Patient, clinical, and physician characteristics were extracted, and descriptive statistics were stratified by referral to PT. Two multivariable logistic regression models were estimated for each diagnostic group (BPPV and other PVDs) to identify predictors of PT referral. RESULTS PT referrals for BPPV increased from 6.2% in the period from 2004 to 2006 to 12.9% in the period from 2013 to 2015, whereas PT referrals for other PVDs decreased from 3.8% in the period from 2004 to 2006 to 0.5% in the period from 2013 to 2015. Other insurance coverage (versus private) and neurologists and other specialists (versus otolaryngologists) were associated with a greater odds of PT referral for BPPV. Visits made in the Midwest and West (versus the Northeast) and in rural versus metropolitan areas had greater odds of PT referral for BPPV. Relative to otolaryngologists, primary care physicians were less likely to refer to PT for other PVDs. Visits made in metropolitan versus rural areas and visits with 1 or more comorbidities (versus none) had greater odds of PT referral for other PVDs. CONCLUSIONS PT referrals remain low for ambulatory care visits for BPPV and other PVDs in the United States. Referral to PT for BPPV and other PVDs varied by insurance type, physician specialty, and office location.

Potential long-term impact of "On The Move" group-exercise program on falls and healthcare utilization in older adults: an exploratory analysis of a randomized controlled trial. BMC Geriatr 2020; 20:105. [PMID: 32178633 PMCID: PMC7075006 DOI: 10.1186/s12877-020-1506-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/19/2019] [Accepted: 03/04/2020] [Indexed: 11/30/2022] Open
Abstract
Background Wellness program participation may reduce the risk of falling, emergency department-use, and hospitalization among older adults. “On the Move” (OTM), a community-based group exercise program focused on the timing and coordination of walking, improved mobility in older adults, but its impact on falls, emergency department-use, and hospitalizations remains unclear. The aim of this preliminary study was to investigate the potential long-term effects that OTM may have on downstream, tertiary outcomes. Methods We conducted a secondary analysis of a cluster-randomized, single-blind intervention trial, which compared two community-based, group exercise programs: OTM and a seated exercise program on strength, endurance, and flexibility (i.e. ‘usual-care’). Program classes met for 50 min/session, 2 sessions/week, for 12 weeks. Older adults (≥65 years), with the ability to ambulate independently at ≥0.60 m/s were recruited. Self-reported incidence of falls, emergency department visitation, and hospitalization were assessed using automated monthly phone calls for the year following intervention completion. Participants with ≥1 completed phone call were included in the analyses. Incidence rate ratios (IRRs) and 95% confidence intervals (CIs) were calculated (reference = usual-care). Results Participants (n = 248) were similar on baseline characteristics and number of monthly phone calls completed. Participants in the seated exercise program attended an average of 2.9 more classes (p = .017). Of note, all results were not statistically significant (i.e. 95% CI overlapped a null value of 1.0). However, point estimates suggest OTM participation resulted in a decreased incidence rate of hospitalization compared to usual-care (IRR = 0.88; 95% CI = 0.59–1.32), and the estimates strengthened when controlling for between-group differences in attendance (adjusted IRR = 0.82; 95% CI = 0.56–1.21). Falls and emergency department visit incidence rates were initially greater for OTM participants, but decreased after controlling for attendance (adjusted IRR = 1.08; 95% CI = 0.72–1.62 and adjusted IRR = 0.96; 95% CI = 0.55–1.66, respectively). Conclusion Compared to a community-based seated group exercise program, participation in OTM may result in a reduced risk of hospitalization. When OTM is adhered to, the risk for falling and hospitalizations are attenuated. However, definitive conclusions cannot be made. Nevertheless, it appears that a larger randomized trial, designed to specifically evaluate the impact of OTM on these downstream health outcomes is warranted.

Abstract
OBJECTIVE To describe and compare triennial rates of physicians' recommendations for physical therapy (PT), lifestyle counseling, and pain medication for knee osteoarthritis (OA) and to identify patient, physician, and practice factors associated with each treatment recommendation. METHODS We conducted a cross-sectional analysis examining data between 2007 and 2015 from the National Ambulatory Medical Care Survey. Visits to orthopedists and primary care physicians for knee OA were identified and assessed for the following: PT referral, lifestyle counseling, nonsteroidal antiinflammatory drug (NSAID) prescriptions, and narcotics prescriptions. Triennial rates for each treatment were calculated. We examined associations between patient (e.g., race, insurance), physician, and practice factors (e.g., ownership, location) and treatments prescribed using multivariate logistic regression that accounted for complex sampling design. RESULTS A total of 2,297 physician visits related to knee OA (~67 [±4] million weighted visits) were identified. For visits to orthopedists, PT and lifestyle recommendation rates declined (158 to 88 of 1,000 visits and 184 to 86 of 1,000 visits, respectively), while NSAID and narcotics prescriptions increased (132 to 278 of 1,000 visits and 77 to 236 of 1,000 visits, respectively) over time (P < 0.05). For visits to primary care physicians, there were no significant changes in rates of PT, lifestyle counseling, and narcotics prescriptions over time, while NSAIDs prescriptions increased (221 to 498 of 1,000 visits; P < 0.05). Treatment recommendations were associated with nonclinical factors, including practice type, location, and type of provider. CONCLUSION In patients with knee OA, PT and lifestyle counseling seem underutilized, while pain medication prescriptions increased during the investigated timeframe. Variation in treatment choices were associated with nonclinical factors. Future research is necessary to examine ways to improve PT and lifestyle utilization and reduce variation in care for knee OA.

Abstract
BACKGROUND Low back pain (LBP) is one of the most prevalent and potentially disabling conditions for which people seek health care. Patients, providers, and payers agree that greater effort is needed to prevent acute LBP from transitioning to chronic LBP. METHODS AND STUDY DESIGN The TARGET (Targeted Interventions to Prevent Chronic Low Back Pain in High-Risk Patients) Trial is a primary care-based, multisite, cluster randomized, pragmatic trial comparing guideline-based care (GBC) to GBC + referral to Psychologically Informed Physical Therapy (PIPT) for patients presenting with acute LBP and identified as high risk for persistent disabling symptoms. Study sites include primary care clinics within each of five geographical regions in the United States, with clinics randomized to either GBC or GBC + PIPT. Acute LBP patients at all clinics are risk stratified (high, medium, low) using the STarT Back Tool. The primary outcomes are the presence of chronic LBP and LBP-related functional disability determined by the Oswestry Disability Index at 6 months. Secondary outcomes are LBP-related processes of health care and utilization of services over 12 months, determined through electronic medical records. Study enrollment began in May 2016 and concluded in June 2018. The trial was powered to include at least 1860 high-risk patients in the randomized controlled trial cohort. A prospective observational cohort of approximately 6900 low and medium-risk acute LBP patients was enrolled concurrently. DISCUSSION The TARGET pragmatic trial aims to establish the effectiveness of the stratified approach to acute LBP intervention targeting high-risk patients with GBC and PIPT.

Abstract
OBJECTIVE This study (1) describes transitional care for stroke patients discharged home from hospitals, (2) compares hospitals' standards of transitional care with core transitional care management (TCM) components recognized by Medicare, and (3) examines the association of policy and hospital specialty designations with TCM implementation. METHODS Hospitals participating in the Comprehensive Post-Acute Stroke Services (COMPASS) Study provided data on their hospital, stroke patient population, and standards of transitional care. Hospital-reported transitional care strategies were compared with the federal TCM definition (2-day follow-up, 14-day visit, non-face-to-face services). We examined the associations of TCM billing, stroke center certification, and Magnet nursing excellence designation with TCM implementation. RESULTS Transitional care varied widely among 41 hospitals in North Carolina and no one strategy was universally applied or provided across hospitals. One third of hospitals met the TCM definition (37% provided telephone follow-up, 76% provided face-to-face provider follow-up, all provided a type of non-face-to-face support). There were no differences between groups (TCM met/not met) in hospital characteristics or transitional care resources and processes. Stroke center certification, Magnet designation, and use of TCM billing codes were not different for hospitals that did and did not meet the TCM definition. CONCLUSIONS There was substantial variation in the provision of strategies supporting stroke patients' transition home from the hospital. Supportive stroke care transitions are essential when more than 50% of stroke patients are discharged home and more than half experience moderate to severe strokes. More research is needed to identify drivers of TCM uptake. CLINICALTRIALSGOV IDENTIFIER NCT02588664.

Abstract
Many individuals who have had a stroke leave the hospital without postacute care services in place. Despite high risks of complications and readmission, there is no standard in the United States for postacute stroke care after discharge home. We describe the rationale and methods for the development of the COMprehensive Post-Acute Stroke Services (COMPASS) care model and the structure and quality metrics used for implementation. COMPASS, an innovative, comprehensive extension of the TRAnsition Coaching for Stroke (TRACS) program, is a clinician-led quality improvement model providing early supported discharge and transitional care for individuals who have had a stroke and have been discharged home. The effectiveness of the COMPASS model is being assessed in a cluster-randomized pragmatic trial in 41 sites across North Carolina, with a recruitment goal of 6,000 participants. The COMPASS model is evidence based, person centered, and stakeholder driven. It involves identification and education of eligible individuals in the hospital; telephone follow-up 2, 30, and 60 days after discharge; and a clinic visit within 14 days conducted by a nurse and advanced practice provider. Patient and caregiver self-reported assessments of functional and social determinants of health are captured during the clinic visit using a web-based application. Embedded algorithms immediately construct an individualized care plan. The COMPASS model's pragmatic design and quality metrics may support measurable best practices for postacute stroke care.

Abstract
Background:
Timely rehabilitation after stroke is essential for optimizing recovery. Patients discharged home can experience unnecessary service delays and gaps in care. Our aim was to examine sociodemographic characteristics associated with receipt of rehabilitation services within 30 days after discharge home in stroke or transient ischemic attack (TIA) patients.
Methods:
COMPASS is a cluster-randomized pragmatic trial measuring the effectiveness of the COMPASS model of care vs. usual care on functional status 90 days after stroke or TIA for patients discharged home. We analyzed data from 369 participants who enrolled in the intervention arm of the COMPASS trial, completed the post-acute clinic visit within 14 days, and the 30-day call between July 2016 and May 15, 2017. For those who were referred to rehabilitation services at hospital discharge or at the clinic visit, receipt of home health (HH) and outpatient (OP) rehabilitation services was reported by the participant during the 30-day call. Sociodemographic differences between those who did and did not receive these services were evaluated. We computed adjusted odds ratios with 95% confidence intervals using logistic regression to identify factors associated with receipt of rehabilitation services.
Results:
Of the 369 patients, 176 (47.7%) had ascertainment of receipt of services. Of the 115 patients referred to HH, 50 (43.5%) received it, and of 85 patients referred to OP therapy, 29 (34.1%) received it. There were no statistically significant differences in sociodemographic characteristics related to receipt of HH, but non-whites were less likely (3 of 20, or 15%) than whites (25 of 64, 34.9%) to receive OP therapy. After adjustment for NIHSS, ambulatory status at hospital admission, and age, non-white participants had a 78% decreased odds (OR 0.22; 95% CI 0.05, 0.95; p=0.04) of receiving OP therapy.
Conclusion:
These findings indicate that a significant gap exists between referral to and receipt of recommended post-acute stroke rehabilitation services. In addition, despite the small sample size, our results suggest that there may be a disparity in receipt of OP therapy for non-white patients relative to white patients.

Abstract
Background Patients discharged home after stroke face significant challenges managing residual neurological deficits, secondary prevention, and pre-existing chronic conditions. Post-discharge care is often fragmented leading to increased healthcare costs, readmissions, and sub-optimal utilization of rehabilitation and community services. The COMprehensive Post-Acute Stroke Services (COMPASS) Study is an ongoing cluster-randomized pragmatic trial to assess the effectiveness of a comprehensive, evidence-based, post-acute care model on patient-centered outcomes. Methods Forty-one hospitals in North Carolina were randomized (as 40 units) to either implement the COMPASS care model or continue their usual care. The recruitment goal is 6000 patients (3000 per arm). Hospital staff ascertain and enroll patients discharged home with a clinical diagnosis of stroke or transient ischemic attack. Patients discharged from intervention hospitals receive 2-day telephone follow-up; a comprehensive clinic visit within 2 weeks that includes a neurological evaluation, assessments of social and functional determinants of health, and an individualized COMPASS Care Plan™ integrated with a community-specific resource database; and additional follow-up calls at 30 and 60 days post-stroke discharge. This model is consistent with the Centers for Medicare and Medicaid Services transitional care management services provided by physicians or advanced practice providers with support from a nurse to conduct patient assessments and coordinate follow-up services. Patients discharged from usual care hospitals represent the control group and receive the standard of care in place at that hospital. Patient-centered outcomes are collected from telephone surveys administered at 90 days. The primary endpoint is patient-reported functional status as measured by the Stroke Impact Scale 16. Secondary outcomes are: caregiver strain, all-cause readmissions, mortality, healthcare utilization, and medication adherence. The study engages patients, caregivers, and other stakeholders (including policymakers, advocacy groups, payers, and local community coalitions) to advise and support the design, implementation, and sustainability of the COMPASS care model. Discussion Given the high societal and economic burden of stroke, identifying a care model to improve recovery, independence, and quality of life is critical for stroke survivors and their caregivers. The pragmatic trial design provides a real-world assessment of the COMPASS care model effectiveness and will facilitate rapid implementation into clinical practice if successful.

Abstract
BACKGROUND Despite different pharmacologic properties, little is known about the comparative safety of sodium ferric gluconate versus iron sucrose in hemodialysis patients. STUDY DESIGN Retrospective cohort study using the clinical database of a large dialysis provider (2004-2005) merged with administrative data from the US Renal Data System. SETTING & PARTICIPANTS 66,207 patients with Medicare coverage who received center-based hemodialysis. PREDICTORS Iron formulation use assessed during repeated 1-month exposure periods (n=278,357). OUTCOMES All-cause mortality, infection-related hospitalizations and mortality, and cardiovascular-related hospitalizations and mortality occurring during a 3-month follow-up period. MEASUREMENTS For all outcomes, we estimated 90-day risk differences between the formulations using propensity score weighting of Kaplan-Meier functions, which controlled for a wide range of demographic, clinical, and laboratory variables. Risk differences were also estimated within various clinically important subgroups. RESULTS Ferric gluconate was administered in 11.4%; iron sucrose, in 48.9%; and no iron in 39.7% of the periods. Risks for most study outcomes did not differ between ferric gluconate and iron sucrose; however, among patients with a hemodialysis catheter, use of ferric gluconate was associated with a slightly decreased risk for both infection-related death (risk difference, -0.3%; 95% CI, -0.5% to 0.0%) and infection-related hospitalization (risk difference, -1.5%; 95% CI, -2.3% to -0.6%). Bolus dosing was associated with an increase in infection-related events among both ferric gluconate and iron sucrose users. LIMITATIONS Residual confounding and outcome measurement error. CONCLUSIONS Overall, the 2 iron formulations studied exhibited similar safety profiles; however, ferric gluconate was associated with a slightly decreased risk for infection-related outcomes compared to iron sucrose among patients with a hemodialysis catheter. These associations should be explored further using other data or study designs.

Abstract
PURPOSE Recent policy changes in the USA have led to an increasing number of patients being placed into observation units rather than admitted directly to the hospital. Studies of administrative data that use inpatient diagnosis codes to identify cohorts, outcomes, or covariates may be affected by this change in practice. To understand the potential impact of observation stays on research using administrative healthcare data, we examine the trends of observation stays, short (≤2 days) inpatient admissions, and all inpatient admissions. METHODS We examined a large administrative claims database of commercially insured individuals in the USA between 2002 and 2011. Observation stays were defined on the basis of the procedure codes reimbursable by Medicare or commercial insurers. We report monthly rates of observation stays and short inpatient admissions overall and by patient demographics. RESULTS We identified 5 355 752 observation stays from 2002 to 2011. Over the course of study, the rate of observation stays increased, whereas the rate of short inpatient stays declined. The most common reason for observation stays was nonspecific chest pain, also the third most common reason for short inpatient stays. The increasing trend of observation stays related to circulatory diseases mirrors the decreasing trend of short inpatient stays. CONCLUSIONS The use of observation stays has increased in patients with commercial insurance. Failure to account for observation stays may lead to an under-ascertainment of hospitalizations in contemporary administrative healthcare data from the USA.

Abstract
Intravenous iron may promote bacterial growth and impair host defense, but the risk of infection associated with iron supplementation is not well defined. We conducted a retrospective cohort study of hemodialysis patients to compare the safety of bolus dosing, which provides a large amount of iron over a short period of time on an as-needed basis, with maintenance dosing, which provides smaller amounts of iron on a regular schedule to maintain iron repletion. Using clinical data from 117,050 patients of a large US dialysis provider merged with data from Medicare's ESRD program, we estimated the effects of iron dosing patterns during repeated 1-month exposure periods on risks of mortality and infection-related hospitalizations during the subsequent 3 months. Of 776,203 exposure/follow-up pairs, 13% involved bolus dosing, 49% involved maintenance dosing, and 38% did not include exposure to iron. Multivariable additive risk models found that patients receiving bolus versus maintenance iron were at increased risk of infection-related hospitalization (risk difference [RD], 25 additional events/1000 patient-years; 95% confidence interval [CI], 16 to 33) during follow-up. Risks were largest among patients with a catheter (RD, 73 events/1000 patient-years; 95% CI, 48 to 99) and a recent infection (RD, 57 events/1000 patient-years; 95% CI, 19 to 99). We also observed an association between bolus dosing and infection-related mortality. Compared with no iron, maintenance dosing did not associate with increased risks for adverse outcomes. These results suggest that maintenance iron supplementation may result in fewer infections than bolus dosing, particularly among patients with a catheter.

Abstract
Patients with ESRD have a substantially increased risk of bone fractures, but the burden of fractures has not been sufficiently characterized in this population. Here, we analyzed fracture rates and postdischarge outcomes using Medicare data from hemodialysis patients in the United States between 2000 and 2009. We assessed adjusted quarterly fracture rates (inpatient and outpatient) and consequences of postfracture hospitalization for seven categories of fracture location. Pelvis/hip, vertebral, and lower leg fractures were the most prevalent fracture types. Pelvis/hip fractures declined slightly from 29.6 to 20.6 per 1000 patient-years between early 2000 and late 2009, but the incidence rates for all other fracture types remained relatively constant. Median lengths of stay for the primary fracture hospitalization ranged from 5 days (interquartile range [IQR], 3-9 days) for forearm/wrist fractures to 8 days (IQR, 5-12 days) for femur fractures. The proportion of patients discharged from the primary hospitalization to a skilled-nursing facility ranged from 28% (ribs/sternum) to 47% (pelvis/hip). A negative binomial regression model suggested that patients had an adjusted mean of 3.8-5.2 additional hospitalizations during the year after discharge from the index hospitalization, varying by fracture type, comprising a mean of 33-52 inpatient days. Case-mix-adjusted mortality rates after discharge ranged from 0.43 to 0.91 per patient-year and were highest for vertebral, pelvis/hip, and femur fractures. In conclusion, fractures in the dialysis population are common and are associated with a substantially increased risk for death and hospitalization.

Abstract
BACKGROUND Intravenous iron is used widely in hemodialysis, yet there are limited data on the effectiveness of contemporary dosing strategies or formulation type. METHODS We conducted a retrospective cohort study using data from the clinical database of a large dialysis provider (years 2004-2008) merged with administrative data from the US Renal Data System to compare the effects of intravenous iron use on anemia management. Dosing comparisons were bolus (consecutive doses ≥100 mg exceeding 600 mg during 1 month) versus maintenance (all other iron doses during the month); and high (>200 mg over 1 month) versus low dose (≤200 mg over 1 month). Formulation comparison was administration of ferric gluconate versus iron sucrose over 1 month. Outcomes were hemoglobin, epoetin dose, transferrin saturation, and serum ferritin during 6 weeks of follow-up. RESULTS We identified 117,050 patients for the dosing comparison, and 66,207 patients for the formulation comparison. Bolus dosing was associated with higher average adjusted hemoglobin (+0.23 g/dL; 95% confidence interval [CI], 0.21-0.26), transferrin saturation (+3.31%; 95% CI, 2.99-3.63), serum ferritin (+151 μg/L; 95% CI, 134.9-168.7), and lower average epoetin dose (-464 units; 95% CI, -583 to -343) compared with maintenance. Similar trends were observed with high-dose iron versus low-dose. Iron sucrose was associated with higher adjusted average hemoglobin (+0.16 g/dL; 95% CI, 0.12-0.19) versus ferric gluconate. CONCLUSIONS Strategies favoring large doses of intravenous iron or iron sucrose lead to improved measures of anemia management. These potential benefits should be weighed against risks, which currently remain incompletely characterized.

Abstract
OBJECTIVES To determine the extent to which demographic and geographic disparities exist in postacute rehabilitation care (PARC) use after hip fracture. DESIGN Cross-sectional analysis of 2 years (2005-06) of population-based hospital discharge data. SETTING All short-term acute care hospitals in four demographically and geographically diverse states (AZ, FL, NJ, WI). PARTICIPANTS Individuals aged 65 and older (mean 82.9) admitted to the hospital with a hip fracture who survived their inpatient stay (N = 64,065). The sample was 75.1% female and 91.5% white, 5.8% Hispanic, and 2.7% black. MEASUREMENTS Whether the participant received institutional PARC; for participants who did not receive institutional care, whether they received home health (HH) care; and for participants who received institutional care, whether they received skilled nursing facility (SNF) or inpatient rehabilitation facility (IRF) care. Multilevel logistic regression analyses were conducted to identify demographic and geographic disparities in PARC use. RESULTS Considering PARC on a continuum from more to fewer hours of care per day (IRF→SNF→HH→no HH), minorities and individuals of lower socioeconomic status (SES) generally received a lower volume of care. Individuals on Medicaid or who were uninsured were less likely to receive institutional care (odds ratio (OR) = 0.23, 95% confidence interval (CI) = 0.18-0.30) and to receive HH (OR = 0.46, 95% CI = 0.30-0.70) and more likely to receive SNF than IRF care (OR = 2.03, 95% CI = 1.36-3.05). Hispanics were less likely to receive institutional care (OR = 0.70, 95% CI = 0.62-0.79), and Hispanics (OR = 1.31) and blacks (OR = 1.49) were more likely to receive SNF than IRF care. There were also geographic differences in PARC. CONCLUSION Several demographic and geographic disparities in PARC use were identified. Future research should confirm these findings and further elucidate factors that contribute to the observed disparities.

Changing patterns of anemia management in US hemodialysis patients. Am J Med 2012; 125:906-14.e9.

Abstract
BACKGROUND Erythropoiesis-stimulating agents and adjuvant intravenous iron have been the primary treatment for anemia in chronic kidney disease. Recent clinical and policy-related events have challenged this traditional paradigm, particularly in regard to erythropoiesis-stimulating agents. Less is known about the impact of these events on intravenous iron use. METHODS United States Renal Data System data (2002-2008) on Medicare hemodialysis patients were examined. For each patient, monthly intravenous iron dose, erythropoiesis-stimulating agent dose, and hemoglobin values were determined. Data were summarized by calendar quarter and plotted for the entire sample and by demographic, clinical, and facility-level subgroups. Marginal means for these variables also were computed to account for changes in patient characteristics over time. RESULTS Quarterly iron use increased from 64% in 2002 to 76% in 2008. Mean quarterly iron dose increased from 500 mg in 2002 to 650 mg in 2008. Mean monthly erythropoiesis-stimulating agent dose (per quarter) increased from 2002 to 2006 and then declined. Mean hemoglobin values followed a pattern similar to erythropoiesis-stimulating agent dose. The same patterns in iron, erythropoiesis-stimulating agent dose, and hemoglobin were generally observed across demographic, clinical, facility, and geographic subgroups, with some important differences between subgroups, specifically race and dialysis vintage. CONCLUSIONS Anemia management patterns have changed markedly between 2002 and 2008, with a steady increase in intravenous iron use even after declines in erythropoiesis-stimulating agent dose and hemoglobin. The clinical impacts of these changes need further evaluation.

Abstract
OBJECTIVE To compare patient profiles and health care use for physician-referred and self-referred episodes of outpatient physical therapy (PT). DATA SOURCE Five years (2003-2007) of private health insurance claims data, from a Midwest insurer, on beneficiaries aged 18-64. STUDY DESIGN Retrospective analyses of health care use of physician-referred (N = 45,210) and self-referred (N = 17,497) ambulatory PT episodes of care was conducted, adjusting for age, gender, diagnosis, case mix, and year. DATA COLLECTION/EXTRACTION Physical therapy episodes began with the physical therapist initial evaluation and ended on the last date of service before 60 days of no further visits. Episodes were classified as physician-referred if the patient had a physician claim from a reasonable referral source in the 30 days before the start of PT. PRINCIPAL FINDINGS The self-referred group was slightly younger, but the two groups were very similar in regard to diagnosis and case mix. Self-referred episodes had fewer PT visits (86 percent of physician-referred) and lower allowable amounts ($0.87 for every $1.00), after covariate adjustment, but did not differ in related health care utilization after PT. CONCLUSIONS Health care use during PT episodes was lower for those who self-referred, after adjusting for key variables, but did not differ after the PT episode.

Abstract
OBJECTIVE To determine the degree to which racial and ethnic disparities in the use of postacute rehabilitation care (PARC) are explained by observed characteristics. DATA SOURCES State inpatient databases (SIDs) for 2005 and 2006 from four diverse states were used to identify patients with stays for joint replacement, stroke, or hip fracture. STUDY DESIGN Our primary outcomes were use of institutional PARC (versus discharge home) and, conditional on discharge to an institution, skilled nursing facility (versus inpatient rehabilitation facility) care. We modified the Oaxaca-Blinder decomposition method to account for the dichotomous outcome and multilevel nature of the data. DATA COLLECTION/EXTRACTION METHODS Discharges from the four SIDs were included if the principal diagnosis (stroke, hip fracture) or procedure (joint replacement) was in the sample inclusion criteria. PRINCIPAL FINDINGS Observed characteristics explained roughly half of the unadjusted differences in use of institutional PARC. Patient-level factors (clinical, age) were more explanatory of disparities in institutional PARC use, while hospital-level factors were more explanatory of skilled nursing facility versus inpatient rehabilitation facility care. CONCLUSIONS Adjustment for characteristics influencing PARC use both mitigated and exacerbated racial/ethnic disparities in use. The degree to which the characteristics explained the disparity varied across conditions and outcomes.
