Randomized Controlled Trial Multicenter Study
Does outpatient telephone coaching add to hospital quality improvement following hospitalization for acute coronary syndrome?
Telephone counseling in chronic disease self-management is increasing, but has not been tested in studies that control for quality of medical care. ⋯ Telephone coaching post-hospitalization for ACS was modestly effective in accomplishing short-term, but not long-term life-style behavior change. Previous positive results shown in primary care did not transfer to free-standing telephone counseling as an adjunct to care following hospitalization.

Randomized Controlled Trial
The impact of perceived treatment assignment on smoking cessation outcomes among African-American smokers.
The double-blind placebo-controlled design is commonly considered the gold standard in research methodology; however, subject expectation bias could subvert blinding. ⋯ Results support previous research that expectation bias associated with judgment of treatment assignment is a strong predictor of outcome and confirms this relationship in a smoking cessation trial using bupropion SR among African-American smokers.
