Cause-specific risk of hospital admission related to extreme heat in older adults.
The purpose of this study was to identify possible causes of hospital admissions during extreme heat events and to estimate their risks using historical data. The investigators found that among older adults, periods of extreme heat were associated with increased risk of hospitalization for fluid and electrolyte disorders, renal failure, urinary tract infection, septicemia, and heat stroke. They noted however, that the absolute risk increase was small and of uncertain clinical importance.

National trends in recurrent AMI hospitalizations 1 year after acute myocardial infarction in Medicare beneficiaries: 1999-2010.
The investigators evaluated changes in the incidence of 1-year recurrent acute myocardial infarction (AMI) hospitalization and mortality. In a national sample of Medicare beneficiaries hospitalized for AMI from 1999 to 2010, they found that hospitalization for recurrent AMI decreased, as did subsequent mortality, albeit to a lesser extent. The risk of recurrent AMI hospitalization declined less in black patients than in whites, increasing observed racial disparities by the end of the study period.

Risk of hospitalization and use of first- versus second-generation antipsychotics among nursing home residents.
This study examined the risk of all-cause hospitalization among dual-eligible elderly nursing home residents who were using antipsychotic medications and found that, on average, there was a 58 percent increase in hospitalization risk after 20 days of using a first-generation drug.

Demographic and clinical predictors of mortality from highly pathogenic avian influenza A (H5N1) virus infection: CART analysis of international cases.
The researchers for this international study sought to model individuals at highest risk of mortality from HPAI N5N1 virus infection in order to inform preventive and therapeutic interventions. They found that age, health expenditure, delay from symptom onset to hospitalization and country are significant predictors of mortality.
