Machine learning prediction of mortality and hospitalization in heart failure with preserved ejection fraction.
This study developed models to predict the risk of death and hospitalization in patients with heart failure (HF) with preserved ejection fraction (HFpEF). Data was used from the TOPCAT (Treatment of Preserved Cardiac Function Heart Failure with an Aldosterone Antagonist) clinical trial. Five methods: logistic regression with a forward selection of variables; logistic regression with a lasso regularization for variable selection; random forest (RF); gradient descent boosting; and support vector machine, were used to train models for assessing risks of mortality and HF hospitalization through 3 years of follow-up and were validated using 5-fold cross-validation. RF was found to be the best performing model for predicting mortality and HF hospitalization. Blood urea nitrogen levels, body mass index, and Kansas City Cardiomyopathy Questionnaire (KCCQ) subscale scores were strongly associated with mortality, while hemoglobin level, blood urea nitrogen, time since previous HF hospitalization, and KCCQ scores were the most significant predictors of HF hospitalization.

Comparison of functional status improvements among patients with stroke receiving postacute care in inpatient rehabilitation vs skilled nursing facilities.
This cohort study compared functional status improvements of poststroke patients who either went to an inpatient rehabilitation facility (IRF) or a skilled nursing facility (SNF). The study used data from Medicare claims for stroke from January 2013 through November 2014. A total of 99,185 patients were studied. Patients admitted to SNFs tended to be older, female, and had a longer hospital length of stay than those admitted to IRFs. Stroke patients admitted to IRFs had larger improvements for mobility score points and for self-care on admission compared with those admitted to SNFs. There was found to be no statistical difference in the odds of 30- to 365-day mortality.

Associations between community well-being and hospitalisation rates: results from a cross-sectional study within six US states.
The objective of this study was to evaluate the association between community well-being, a positively framed, multidimensional assessment of the health and quality of life of a geographic community, and hospitalisation rates. The investigators found that community well-being was inversely associated with local hospitalisation rates. They suggest that in addition to health and quality-of-life benefits, higher community well-being may also result in fewer unnecessary hospitalisations.

Did Medicare Part D affect national trends in health outcomes or hospitalizations? A time-series analysis.
The researchers examined changes in health outcomes and medical services in the Medicare population after implementation of Medicare Part D. They found that 5 years after implementation, and contrary to previous reports, there was no evidence of Part D's effect on a range of population-level health indicators among Medicare enrollees. Further, there was no clear evidence of gains in medical care efficiencies.

The influence of hospitalization or intensive care unit admission on declines in health-related quality of life.
The researchers sought to determine the association of an ICU stay with declines in health-related quality of life (HRQoL). prehospital. They found that hospitalization is associated with increased risk of impairment in HRQoL after discharge, yet the overall magnitude of this reduction is small and similar between non-ICU hospitalized and critically ill patients.

Predictors of medical or surgical and psychiatric hospitalizations among a population-based cohort of homeless adults.
This study identified factors associated with inpatient hospitalizations among a population-based cohort of homeless adults in Toronto, Ontario. Health care need was a strong predictor of medical or surgical and psychiatric hospitalizations. Some hospitalizations among homeless adults were potentially avoidable, whereas others represented an unavoidable use of health services.
