Association of cardiac rehabilitation with decreased hospitalization and mortality risk after cardiac valve surgery.
Investigators sought to characterize cardiac rehabilitation (CR) enrollment after cardiac valve surgery and its association with outcomes, including hospitalizations and mortality. Subjects were all fee-for-service Medicare beneficiaries undergoing open cardiac valve surgery in 2014, identified by inpatient diagnosis codes for open aortic, mitral, tricuspid, and pulmonary valve surgery. They found that fewer than half of Medicare beneficiaries undergoing cardiac valve surgery enrolled in CR programs, and there were marked racial/ethnic disparities among those who do. They recommend further study on barriers to CR enrollment in this population.

Characteristics of long-term care residents that predict adverse events after hospitalization.
This study examined the characteristics of long-term care (LTC) residents that predict adverse events (AEs) after discharge from recent hospitalization. This cohort study looked at AEs that occurred at 32 nursing homes from six New England states. AE incidents involving a total of 555 LTC residents with 762 transitions from the hospital back to LTC were reviewed. The association between all AEs and preventable AEs developing in the 45 days following discharge back to LTC was measured. There were 283 discharges with one or more AEs and 212 with preventable AEs. Characteristics independently associated with higher risk of AEs included hospital length of stay (LOS) 9 or more days, 18 or more regularly scheduled medications, and 19 and above on the dependency in activities of daily living (ADL) scale.

Comparison of measures to predict mortality and length of stay in hospitalized patients.
This study compared performance of five measures in order to predict mortality and length of stay (LOS) in hospitalized adults using claims data; the measures included three comorbidity composite scores, 3 M risk of mortality, and 3 M severity of illness subclasses. Binary logistic and zero-truncated negative binomial regression models were applied to a 2-year retrospective dataset of adult inpatient admissions from a large hospital system in New York City. All five measures demonstrated a good to strong model fit for predicting in-hospital mortality. The authors conclude that these measures can guide nurse managers in assigning nursing care and coordinating patient services, as well as administrators in supporting optimal nursing care more effectively and efficiently.

Assessment of extreme heat and hospitalizations to inform early warning systems.
The purpose of this study was to conduct multistate analyses to explore associations between heat and all-cause and cause-specific hospitalizations, in order to inform the design and development of heat-health early warning systems. Researchers used a two-stage analysis to estimate heat-health risk relationships between heat index and hospitalizations, then used the results to identify heat index ranges that corresponded with a significant heat-attributable burden and compared these to National Weather Service (NWS) heat alert criteria used during the same time period. The study’s conclusions suggest that locally specific health evidence can inform and calibrate heat alert criteria.
