Approaches to address premature death of patients when assessing patterns of use of health care services after an index event.
In this study, the investigators compared different approaches for cohort definition (restriction by survival time vs. comorbidity score) and analysis method [Kaplan-Meier (KM) vs. competing risk] when assessing patterns of guideline adoption in elderly patients. They found that the KM method consistently overestimated the competing risk method. They suggest that competing risk approaches avoid unrealistic mortality assumptions and lead to interpretations of estimates that are more meaningful.

Frequency of care and mortality following an incident diagnosis of peripheral artery disease in the inpatient or outpatient setting: the ARIC (Atherosclerosis Risk in Communities) study.
Researchers analyzed frequency of care and mortality date for patients with an initial peripheral artery disease (PAD) diagnosis in the outpatient or inpatient setting. Data was analyzed from the ARIC (Atherosclerosis Risk in Communities) study cohort linked with Centers for Medicare and Medicaid Services fee-for-services claims data for 2002-2012. Patients diagnosed in the outpatient setting had higher follow-up rates with lower hospitalizations and mortality than those diagnosed in the inpatient setting.
