Geriatric syndrome risk factors among hospitalized postacute Medicare patients.
The purpose of this study was to assess the association of geriatric syndrome risk factors with postacute utilization among hospitalized Medicare patients (both Medicare Advantage [MA] and fee-for-service [FFS] cohorts) and to examine patterns of postacute care for MA and FFS cohorts with high geriatric syndrome risk. The investigators found that geriatric syndrome risk factors not only play a role in postacute care and inpatient utilization in MA and FFS cohorts but also explain different utilizations between MA and FFS cohorts.

Temporal trends in heart failure incidence among Medicare
This retrospective, national cohort study looked at temporal trends in heart failure (HF) incidence among Medicare beneficiaries from 2011 to 2016. There had been a decline in claims during that time period. Five percent of all fee-for-service Medicare beneficiaries with no prior HF diagnosis were followed up from 2011-2016. Annual trends were examined in HF incidence among groups with and without primary HF risk factors (hypertension, diabetes, and obesity) and predisposing cardiovascular conditions (acute myocardial infarction (MI) and atrial fibrillation (AF). Of the approximately 1.8 million Medicare beneficiaries at risk for HF, 249,832 had a new diagnosis of HF. The prevalence of all 5 risk factors had increased during the 5-year study period. There was a relative decline in HF incidence among beneficiaries with primary HF risk factors, but incidence increased among individuals with acute MI and AF.

Prehospital and posthospital fall injuries in older US adults.
Investigators estimated the risk of older adult fall injury within and across discrete periods during a 12-month care episode anchored by an acute hospitalization using national data from 2006 to 2014. Participants in this cohort study included Medicare fee-for-service beneficiaries aged 65 and older from the Health and Retirement Study. The investigators found that an episode-based assessment of fall injury illustrated substantial variability in period-specific risks over an extended period including an anchor hospitalization. Risk transitions between periods included sizable increases just before hospitalization that do not fully subside after hospital discharge. Financial incentives to coordinate hospital and posthospital care for patients at risk for fall injury are needed.

Comparing survey-based frailty assessment to Medicare claims in predicting health outcomes and utilization in Medicare beneficiaries.
The purpose of this study was to assess two models for the prediction of health utilization and functions using standardized in-person assessments of frailty and administrative claims-based geriatric risk measures among Medicare fee-for-service beneficiaries aged 65 years and above. Outcomes of hospitalizations, death, and functional help were investigated for participants in the 2011 National Health and Aging Trends Study.

Identification of Medicare recipients at highest risk for Clostridium difficile infection in the US by population attributable risk analysis.
This study determined the population attributable risk percent (PAR%) for Clostridium difficile infection (CDI) in various subpopulations in the Medicare 5% random sample. It found that small and identifiable subpopulations that account for relatively large proportions of CDI cases in the elderly were identified. These data can be used to target specific subpopulations for CDI prevention interventions.

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.

Claims-based algorithms for identifying Medicare beneficiaries at high estimated risk for coronary heart disease events: a cross-sectional study.
The researchers sought to develop claims-based algorithms to identify individuals at high risk for coronary artery disease (CHD) and to identify low-density lipoprotein (LDL) cholesterol among statin users at high risk for CHD events. They found that despite low sensitivity, the high predictive value of their algorithm for high risk for CHD events supports the use of claims to identify Medicare beneficiaries at high risk for CHD events.
