: Sixty percent of US adults have at least one chronic condition, and more than 40% have multiple conditions. Self-management (SM) by the individual, along with self-management support (SMS) by others, are nonpharmacological interventions with few side effects that are critical to optimal chronic disease control. Ruiz and colleagues laid the conceptual groundwork for surveillance of SM/SMS at 5 socio-ecological levels (individual, health system, community, policy, and media). We extend that work...

Frequent emergency department (ED) use is a public health and policy relevant concern but has not previously been examined in the Medicare population. We conducted a retrospective, claims-based analysis of a nationally representative 20% sample of fee-for-service Medicare beneficiaries in 2010 (n = 5,778,038) to examine frequent ED use. We used multinomial logistic regression to study the relationship between frequent ED use and sociodemographic, outpatient care, and clinical characteristics. Fa...

Study objective We examine factors associated with persistent frequent emergency department (ED) use during a 2-year period among Medicare beneficiaries. Methods We conducted a retrospective, claims-based analysis of fee-for-service Medicare beneficiaries, using the Chronic Condition Data Warehouse's random 20% sample files. We used multinomial logistic regression models to compare frequent ED use (defined as 4 or more ED visits per year) with infrequent use (1 to 3 visits per year), non-ED use,...

The widely disseminated lay-led A Matter of Balance (MOB) program aims to help older adults reduce their risk of falling and associated activity limitations. This study examined effects of MOB participation on health service utilization and costs for Medicare beneficiaries, as a part of a larger effort to understand the value of ...
