BACKGROUND Poor medication adherence is a significant problem in hypertensive African Americans. Although motivational interviewing (MINT) is effective for adoption and maintenance of health behaviors in patients with chronic diseases, its effect on medication adherence remains untested in this population. METHODS This randomized controlled trial tested the effect of a practice-based MINT counseling versus usual care (UC) on medication adherence and blood pressure (BP) in 190 hypertensive African Americans (88% women; mean age 54 years). Patients were recruited from two community-based primary care practices in New York City. The primary outcome was adherence measured by electronic pill monitors; the secondary outcome was within-patient change in office BP from baseline to 12 months. RESULTS Baseline adherence was similar in both groups (56.2% and 56.6% for MINT and UC respectively, p = 0.94). Based on intent-to-treat analysis using mixed effects regression, a significant time X group interaction with model-predicted post-treatment adherence rates of 43% and 57% were found in the UC and MINT groups, respectively (p = 0.027), with a between-group difference of 14% (95% CI, −0.2% to −27%). The between-group difference in systolic and diastolic BP was −6.1 mm Hg (p = .065) and −1.4 mm Hg (p = .465), respectively, in favor of the MINT group. CONCLUSIONS A practice-based MINT counseling led to steady maintenance of medication adherence over time, compared to significant decline in adherence for UC patients. This effect was associated with a clinically meaningful net reduction in systolic BP in favor of the MINT group.

Objective. In many developing countries, access to medical imaging is limited by availability of resources. Portable ultrasound shows great promise to meet the needs in these countries because it is transportable and relatively inexpensive, and it has a wide range of applications. As part of the Ghana Health Mission, SekondiTakoradi, Ghana, we explored the utility of ultrasound in primary care and hospital settings during March 2004. Our objective was to evaluate the clinical utility of a portable ultrasound machine in a variety of physical conditions and multiple clinical scenarios. Methods. Ultrasound examinations were performed at 2 primary care sites and 2 hospitals using a portable ultrasound machine with linear and curved linear phased array transducers. Most ultrasound examinations were musculoskeletal, with the remainder being obstetric, pelvic, breast, vascular, abdominal, and genitourinary examinations. Results. In clinic settings, musculoskeletal ultrasound represented 46% (16) of the ultrasound examinations performed, and 29% (10) of the cases were a combination of abdominal, pelvic, and genitourinary examinations. In hospital settings, abdominal, pelvic, and genitourinary ultrasound examinations combined were 56% (18), and musculoskeletal was 41% (13). Of the 67 ultrasound examinations performed, 81% (54) showed abnormal findings, 81% (54) were considered to add to the clinical diagnosis, and 40% (27) influenced medical care for the patients. Conclusions. This experience shows the usefulness of portable ultrasound examinations performed by a skilled radiologist in a clinical setting in Ghana; the challenge is to address how to best incorporate ultrasound into the current practice of medical professionals in developing countries.
