Adherence to medication regimens for type 2 diabetes is strongly associated with metabolic control in an indigent population; African-Americans have lower adherence and worse metabolic control. Greater efforts are clearly needed to facilitate diabetes self-management behaviors of low-income populations and foster culturally sensitive and appropriate care for minority groups.

BACKGROUND: Successful control of diabetes mellitus requires lifelong adherence to multiple self-management activities in close collaboration with health professionals. We examined the association of such control with appointment keeping behavior in a rural health system. METHODS: Among 4,253 predominantly lower socioeconomic status patients with diabetes, the association of metabolic control (most recent A1c <7% or >9% in two models of respectively 'good' and 'poor' control) with 'missed appointment rate' over a 3-year period was examined using multiple logistic regression. MAIN RESULTS:For each 10% increment in missed appointment rate, the odds of good control decreased 1.12× (p<0.001) and the odds of poor control increased 1.24× (p<0.001). The missed appointment rate was substantially higher among African-American patients (15.9% vs. 9.3% for white patients, p<0.001). Controlling for the missed appointment rate and insurance status in multivariate analysis attenuated the racial association with good control, and the racial association with poor control was no longer significant. Older, white patients with health insurance tended to have significantly better metabolic control. There was no independent association of metabolic control with patient income, gender, or number of primary care visits.CONCLUSION: Adherence to appointments, independent of visit frequency, was a strong predictor of diabetes metabolic control. We hypothesize that missed appointment behavior may serve as an indicator for other diabetes adherence behaviors and associated barriers that serve to undermine successful diabetes self-management.KEY WORDS: appointment adherence; a1c; diabetes mellitus.

Physicians reported high and increasing rates of PSA testing from 1993 to 1998 and more favorable attitudes toward PSA testing. Despite conflicting expert recommendations and a lack of consistent, high-quality supporting evidence, PSA screening appears to be increasingly considered a standard of care by practicing physicians. However, beliefs other than improved patient outcomes due to screening may be the primary drivers of increased PSA testing.

Implementation of an education and feedback-supported acute low back pain care guideline for primary care clinicians was associated with an increase in guideline-consistent behavior. Patient education materials did not enhance guideline effectiveness. Implementation barriers could limit the utility of this approach in usual care settings.

In a rural indigent population, medication refill adherence was associated with race, age, and prescription length, though these factors explained only a small amount of adherence variability. Although ingestion adherence is the goal, refill adherence is a necessary condition for ingestion adherence. To enhance adherence, physicians need better predictors to target their efforts to patients most in need of attention. Prescription claims data could serve this purpose.
