Importance: Enrollment in Medicare Advantage (MA) has been increasing and has reached one-third of total Medicare enrollment. Because of data limitations, direct comparison of inpatient rehabilitation services between MA and traditional Medicare (TM) beneficiaries has been very scarce. Subgroups of elderly individuals admitted to inpatient rehabilitation facilities (IRFs) may experience different care outcomes by insurance types.

Background: Some clinical features of patients after stroke may be modifiable and used to predict outcomes. Identifying these features may allow for refining plans of care and informing estimates of posthospital service needs. The purpose of this study was to identify key factors that predict functional independence and living setting 3 months after rehabilitation hospital discharge by using a large comprehensive national data set of patients with stroke.

Burden of care (BoC) is the amount of time a patient requires direct, daily assistance from another person to meet basic needs in the home; it is based on a patient's functional level, obtained using the Functional Independence Measure. Inpatient BoC is a patient's projected resource utilization during a stay at an inpatient facility, assessed using the Northwick Park Dependency Scale. At the outpatient level, function and BoC can be assessed using the LIFEware System.

Initial studies examining patient demographics and outcomes in traumatic brain injury (TBI) suggest a trend toward increasing patient age and decreasing rehabilitation length of stay, but such studies have not been repeated since the passage of healthcare reform legislation, most notably the Affordable Care Act. This study utilized the Uniform Data System for Medical Rehabilitation (UDSMR) for patients admitted to medical rehabilitation facilities after sustaining a TBI from January 1, 2002 through December 31, 2016. Trends for demographic and medical data were evaluated.

Background: The gold standards for assessing ambulation are the Expanded Disability Status Scale (EDSS) and the Timed 25-Foot Walk (T25FW) test. In relation with these measures, we assessed the reliability and validity of four clinical gait measures: the Timed Up and Go (TUG) test, the Dynamic Gait Index (DGI), the 2-Minute Walk Test (2MWT), and the 6-Minute Walk Test (6MWT). Patient self-report of gait was also assessed using the 12-item Multiple Sclerosis Walking Scale (MSWS-12).

Objectives: Functional status is associated with patient outcomes, but is rarely included in hospital readmission risk models. The objective of this study was to determine whether functional status is a better predictor of 30-day acute care readmission than traditionally investigated variables including demographics and comorbidities.

Design: Retrospective database analysis between 2002 and 2011.

Background: A significant proportion of burn injury patients are admitted to inpatient rehabilitation facilities (IRFs). There is increasing interest in the use of functional variables, such as cognition, in predicting IRF outcomes. Cognitive impairment is an important cause of disability in the burn injury population, yet its relationship to IRF outcomes has not been studied.

Research suggests high-voltage, pulsed-current electric therapy (HVPC) is safe and effective for treating chronic wounds, and some data suggest silver- and collagen-based dressings may facilitate healing. A combination therapy utilizing both HVPC and silver-collagen dressing may present clinical advantages. To explore the effect of the combined therapy for chronic full-thickness wounds, a prospective, consecutive case series study was conducted.

Article Synopsis
  • The study investigates the causes of acute care readmissions in stroke patients undergoing inpatient rehabilitation, focusing on whether functional status or medical comorbidities serve as better predictors of readmission risk.
  • A large analysis using data from over 800,000 patients from 2002 to 2011 revealed that 11% of stroke patients were readmitted to acute care hospitals, with a detailed performance comparison of predictive models based on age, functional status, and medical comorbidities.
  • The results indicated that models incorporating functional status, particularly the Basic-Plus model, outperformed those focused mainly on age and medical comorbidities, suggesting functional status is crucial in predicting readmission risk.

Objective: The aim of this study was to determine whether functional status, as measured by the AcuteFIM instrument, can be used to predict discharge destination of stroke patients from the acute hospital setting.

Design: A retrospective cohort study was carried out in an urban academic medical center. Data were collected on 481 new-onset stroke patients 18 yrs or older in an acute hospital between January 1 and September 30, 2013.

Objectives: To test whether functional status is a robust predictor of acute care readmission risk in patients who have been discharged to an inpatient rehabilitation facility (IRF) following a unilateral hip fracture.

Study Design: Retrospective database study using a large administrative data set.

Methods: A retrospective analysis of data from the Uniform Data System for Medical Rehabilitation from the years 2002 to 2011 was performed, examining patients with an impairment of unilateral hip fracture.

Purpose: To examine the association of inpatient rehabilitation facility (IRF) length of stay (LOS) with stroke patient outcomes.

Design: A secondary data analysis of the Uniform Data System for Medical Rehabilitation database.

Methods: Stroke patients discharged from IRFs in the United States between 2009 and 2011 were identified and divided into mild (n = 639), moderate (n = 2,065), and severely (n = 2,077) impaired groups.

Background And Purpose: Identifying clinical data acquired at inpatient rehabilitation admission for stroke that accurately predict key outcomes at discharge could inform the development of customized plans of care to achieve favorable outcomes. The purpose of this analysis was to use a large comprehensive national data set to consider a wide range of clinical elements known at admission to identify those that predict key outcomes at rehabilitation discharge.

Methods: Sample data were obtained from the Uniform Data System for Medical Rehabilitation data set with the diagnosis of stroke for the years 2005 through 2007.

Background: Documentation of a new or worsened pressure ulcer is a new, required quality indicator for all inpatient rehabilitation facilities (IRFs) in the United States; however, there is little research regarding risk factors for pressure ulcers among patients seen in IRFs.

Objective: To examine the risk factors for development of a new or worsened pressure ulcer among patients seen in IRFs.

Design: A retrospective cohort study.

Objective: The aim of this study was to examine the associations of onset days, time from stroke onset to inpatient rehabilitation facility (IRF) admission, and patient outcomes (FIM gain, discharge destination, and IRF length of stay), using nationally representative data.

Design: A secondary data analysis was conducted on a random sample of stroke patients discharged from IRFs in the United States between 2009 and 2011, including mildly (n = 649), moderately (n = 2185), and severely (n = 2390) impaired patients.

Results: The study sample had a median of onset days of 5.

Background: Burn survivors tend to have complex medical issues requiring rehabilitation to improve overall function and quality of life. A subset of burn patients treated in inpatient rehabilitation facilities (IRFs) may require more than 1 rehabilitation stay for the same injury.

Objective: To compare the rehabilitation outcomes among burn patients admitted to an IRF who were discharged to acute care and then readmitted to an IRF with burn patients admitted to an IRF only 1 time.

The purpose of this study was to explore trajectories of recovery in patients with lower extremity joint replacements receiving post-acute rehabilitation. A retrospective cohort design was used to examine data from the Uniform Data System for Medical Rehabilitation (UDSMR®) for 7434 patients with total knee replacement (TKR) and 4765 patients with total hip replacement (THR) who received rehabilitation from 2008 to 2010. Functional Independence Measure (FIM)™ instrument ratings were obtained at admission, discharge, and 80-180 days after discharge.
