Review: disease management programmes improve detection and care of people with depression.

Study selection and analysis: Inclusion criteria: experimental or quasi-experimental studies assessing systematic approaches to care using multiple types of treatment modalities—for example, guidelines, protocols, algorithms, or care plans, and using multiple types of treatment modalities—for example, education, reminders, and financial incentives for patients and providers. Exclusion criteria: studies reporting on single treatment types or on paediatric cases only, or lacking sufficient information to calculate an effect size. Data were extracted and study effect sizes calculated and pooled using a random effects model.
