Background: Guidelines recommend that patients with low ejection fraction (EF) after myocardial infarction (MI) have their EF reassessed 40 days after MI for implantable cardioverter-defibrillator (ICD) candidacy. This study examines rates of EF reassessment and their association with 1-year ICD implantation in post-MI patients with low EF.Methods: We examined rates of postdischarge EF reassessment and ICD implantation among 10 289 Medicare-insured patients ≥65 years of age with an EF≤35% during the index MI admission from January 2007 through September 2010 in ACTION Registry-GWTG (Acute Coronary Treatment and Intervention Outcomes Network Registry-Get With The Guidelines). Multivariable Cox models tested the association between time-dependent EF reassessment and 1-year ICD implantation, stratified by revascularization status during the index MI admission.Results: Among patients with EF ≤35% during the index MI admission, 66.8% (95% confidence interval [CI], 65.9-67.8) had EF reassessment within the next year. Revascularized patients were more likely to have EF reassessment (76.9% [95% CI, 75.8-78.0)] versus 53.7% [95% CI, 52.2-55.2]; P<0.001) and had shorter times to EF reassessment (median, 67 versus 84 days; P<0.001) than nonrevascularized patients. Among patients with EF reassessment, only 11% received an ICD within 1 year. Reassessment of EF was associated with a higher likelihood of ICD implantation for both revascularized (unadjusted, 12.1% versus 2.4%, P<0.001; adjusted hazard ratio, 10.6, 95% CI, 7.7-14.8) and nonrevascularized (unadjusted, 10.0% versus 1.7%, P<0.001; adjusted hazard ratio, 6.1, 95% CI, 4.1-9.2) patients.Conclusions: In US practice, EF reassessments are commonly performed among patients with MI with an initially reduced EF. Although 1-year EF reassessment is associated with increased likelihood of ICD implantation, 1-year ICD implantation rates remain very low even among patients with EF reassessment, regardless of revascularization status.

Background: Despite years of research and increasingly evidence-based practice, falls continue to be the most commonly reported adverse events experienced by hospitalized adults. Yet a majority of the relevant research has focused on predicting and preventing falls in general; there has been little focus on injurious falls. Purpose: The purpose of this retrospective study was to determine which patient factors are associated with injurious falls in hospitalized adults. Methods: The study site's adverse event reporting database was used to identify 1,369 patients who fell between January 1, 2006, and October 31, 2013. Of these, 381 (27.8%) subjects suffered injurious falls. Variables of interest included age, sex, fall history, use of diuretics, use of central nervous system medications, cognitive impairment, primary discharge diagnoses, abnormal laboratory values, impaired mobility, and body mass index. Findings: Bivariate analysis revealed a statistically significant association between injurious falls and having a primary discharge diagnosis of "symptoms, signs, and ill-defined conditions." Having this discharge diagnosis was a significant predictor of injurious falls. Conclusions: Findings from this study may help hospital clinicians to better identify which patients are most at risk for injurious falls and to create better fall-related injury prevention interventions.
