RESUMO
OBJECTIVE: To evaluate the effectiveness of an intensive, multidisciplinary patient-centered approach involving a pharmacist and a dietician in a population of uninsured free clinic patients with diabetes and hypertension. METHODS: A single-center retrospective chart review of a quality improvement project. All patients had diagnoses of diabetes and hypertension and a most recent hemoglobin A1c ≥ 9.0%. Patients met individually with a pharmacist and a dietician during 6 encounters over 12 months. The pharmacist made medication changes, encouraged lifestyle reflections, and helped patients create and track self-management goals. The dietician helped patients plan strategies for diet and exercise. The primary outcome was a change in mean hemoglobin A1c. RESULTS: Of 30 enrolled patients, 17 completed three months of treatment, and seven completed 12 months. The 17 patients who completed three months of treatment had the following characteristics: mean age 55.5 years; mean hemoglobin A1c 11.5%; 82% were taking two or more antidiabetic medications; 59% were taking two or more antihypertensive medications. Significant reductions in mean hemoglobin A1c values were observed at three months (-3.4%, P<0.0001) and twelve months (-4.0%, P=0.0156). Reductions in systolic blood pressure were also observed at three months (-6 mmHg, P=0.1060) and twelve months (-17 mmHg, P=0.2188). CONCLUSIONS: Large and significant hemoglobin A1c reductions were observed in free clinic patients with diabetes refractory to traditional medical management. Goal-oriented patient empowerment effectively improves a wide range of patient outcomes in the free clinic setting. Other free clinics can implement this collaborative, multidisciplinary model with access to similar personnel.
RESUMO
BACKGROUND: A free clinic is a health care delivery model that provides primary care and pharmaceutical services exclusively to uninsured patients. With a multidisciplinary volunteer clinical staff, which includes physicians, social workers, dieticians, and osteopathic medical students, St. Luke's Free Medical Clinic (SLFMC) cares for over 1700 patients annually in Spartanburg, South Carolina. OBJECTIVE: This study aims to measure the change, over time, in patient hemoglobin A1c measurements at the SLFMC to quantify the success of the clinic's diabetes treatment program. METHODS: A prospective-retrospective chart review of patients (n=140) enrolled at the SLFMC between January 1, 2018, and January 1, 2021, was performed. Patients were stratified as having controlled (hemoglobin A1c<7.0, n=53) or uncontrolled (hemoglobin A1c≥7.0, n=87) diabetes relative to a therapeutic hemoglobin A1c target of 7.0, which is recommended by the American Diabetes Association. For both controlled and uncontrolled groups, baseline hemoglobin A1c values were compared to subsequent readings using a Wilcoxon matched-pairs signed rank test. Results from the SLFMC population were compared to the published literature on hemoglobin A1c from other free clinics. RESULTS: Patients with uncontrolled diabetes experienced significant reductions in median hemoglobin A1c at both 6 months (P=.006) and 1 year (P=.002) from baseline. Patients with controlled diabetes showed no significant changes. Black and Hispanic patients with uncontrolled diabetes experienced a 1.0% mean improvement in hemoglobin A1c over the study window. The SLFMC's wholly uninsured patient population showed a population rate of controlled diabetes (42%), which was similar to recent nationwide averages for adults with diabetes (51% to 56%), as reported by the National Health and Nutrition Examination Survey. The clinic's Hispanic population (n=47) showed the greatest average improvement in hemoglobin A1c of any ethnic group from baseline. Additionally, 61% of the SLFMC's Black population (n=33) achieved a hemoglobin A1c of <7.0 by the end of the study window, which surpassed the nationwide averages for glycemic control. CONCLUSIONS: We present free clinic hemoglobin A1c outcomes obtained through a retrospective chart review. Uninsured patients treated for diabetes at the SLFMC show a reduction in hemoglobin A1c, which is comparable to nationwide standards, although average hemoglobin A1c levels in this study were higher than nationwide averages. Black and Hispanic patients with uncontrolled diabetes showed a mean 1% improvement in hemoglobin A1c levels. These results represent some of the first in the literature emerging from a free clinic that is not affiliated with a major medical school.
