The objective of this study was to determine the effectiveness of interventions
targeted at providers to enhance the use of mammography. We performed
a meta-analysis and included United States studies that used a randomized
or nonrandomized concurrent control design, had defined outcomes, and
presented data that could be abstracted for reanalysis. Interventions
were classified as behavioral, cognitive, or sociological and further
categorized by the type of control group (active versus usual care). Data
were combined using DerSimonian and Laird random effects models to yield
summary effect sizes. Thirty-five studies met the inclusion criteria.
All types of interventions targeted at providers were effective in increasing
mammography rates. Behavioral interventions increased screening by 13.2%
[95% confidence interval (CI), 7.8-18.4] as compared with usual care and
by 6.8% (95% CI, 4.8-8.7) as compared with active controls. Cognitive
intervention strategies improved mammography rates by 18.6% (95% CI, 12.8-24.4).
Sociological interventions also had a similar magnitude of effect on screening
rates (13.1% increase; 95% CI, 6.8-19.3). Interventions targeting both
patients and providers were not significantly better at increasing screening
than those targeting providers alone, and multiple approaches (e.g., behavioral
and cognitive) were generally not more effective than a single approach.
All interventions targeted at physicians were effective in increasing
screening rates. Decisions to use a particular approach will depend on
resources, expertise, feasibility, and cost effectiveness.
