Medical Outcomes Study:  Measures of Patient Adherence

The Medical Outcomes Study was a two-year study of patients with chronic conditions. As part of the study, the research team assessed how well patients adhered to treatment regimes.

The measures of patient adherence include two types of measures. A general measure assessed patients' adherence to treatment for heart disease, diabetes, and hypertension; a specific measure assessed patients' adherence to treatment recommendations for the tracer conditions studied in the MOS and also gathered information about how often the patient carried out the recommendations.
