Purpose: To evaluate whether implementation factors or fidelity moderate chronic disease self-management education program outcomes.
Design: Meta-analysis of 34 Arthritis Self-Management Program and Chronic Disease Self-Management Program studies.
Setting: Community.
Introduction: The Chronic Disease Self-Management Program (CDSMP) is a community-based self-management education program designed to help participants gain confidence (self-efficacy) and skills to better manage their chronic conditions; it has been implemented worldwide. The objective of this meta-analysis was to quantitatively synthesize the results of CDSMP studies conducted in English-speaking countries to determine the program's effects on health behaviors, physical and psychological health status, and health care utilization at 4 to 6 months and 9 to 12 months after baseline.
Methods: We searched 8 electronic databases to identify CDSMP-relevant literature published from January 1, 1999, through September 30, 2009; experts identified additional unpublished studies.
Objective: To estimate the prevalence and distribution of age-related macular degeneration (AMD) in the United States by age, race/ethnicity, and gender.
Methods: Summary prevalence estimates of drusen 125 microm or larger, neovascular AMD, and geographic atrophy were prepared separately for black and white persons in 5-year age intervals starting at 40 years. The estimated rates were based on a meta-analysis of recent population-based studies in the United States, Australia, and Europe.
Objective: To determine the prevalence of diabetic retinopathy among adults 40 years and older in the United States.
Methods: Pooled analysis of data from 8 population-based eye surveys was used to estimate the prevalence, among persons with diabetes mellitus (DM), of retinopathy and of vision-threatening retinopathy-defined as proliferative or severe nonproliferative retinopathy and/or macular edema. Within strata of age, race/ethnicity, and gender, US prevalence rates were estimated by multiplying these values by the prevalence of DM reported in the 1999 National Health Interview Survey and the 2000 US Census population.
Objective: To estimate the US prevalence of diabetic retinopathy (DR) among persons with type 1 diabetes mellitus (DM).
Methods: Prevalence data from the New Jersey 725 and Wisconsin Epidemiologic Study of Diabetic Retinopathy were used to estimate the prevalence of DR by age, gender, and race among persons 18 years and older having type 1 DM diagnosed before age 30 years. Severity of DR was determined via masked grading of 7-field stereoscopic fundus photographs.
Objective: To estimate the prevalence and distribution of open-angle glaucoma (OAG) in the United States by age, race/ethnicity, and gender.
Methods: Summary prevalence estimates of OAG were prepared separately for black, Hispanic, and white subjects in 5-year age intervals starting at 40 years. The estimated rates were based on a meta-analysis of recent population-based studies in the United States, Australia, and Europe.
Objective: To estimate the prevalence of refractive errors in persons 40 years and older.
Methods: Counts of persons with phakic eyes with and without spherical equivalent refractive error in the worse eye of +3 diopters (D) or greater, -1 D or less, and -5 D or less were obtained from population-based eye surveys in strata of gender, race/ethnicity, and 5-year age intervals. Pooled age-, gender-, and race/ethnicity-specific rates for each refractive error were applied to the corresponding stratum-specific US, Western European, and Australian populations (years 2000 and projected 2020).
