Longitudinal Hypertension Outcomes at Four Student-Run Free Clinic Sites.
OBJECTIVE
Student-Run Free Clinics (SRFCs) play a significant role in medical education yet there is minimal information about patient outcomes over time in this setting. The purpose of this study was to assess longitudinal outcomes of hypertension management during routine care at four SRFC sites, while comparing control rates with national standards, and examining for characteristics independently associated with uncontrolled hypertension.


METHODS
The authors conducted a retrospective medical record review of visits from January 2004 through April 2016 with an initial visit for hypertension and a follow-up visit 9 to 15 months later. Hypertension control was analyzed using descriptive statistics, paired t tests, logistic regression, and a longitudinal linear mixed-effects model.


RESULTS
This study included 496 patients and 4,798 visits. The mean age was 50.9 (SD 10.8) years old, 71.2% (346) were Latinos, 63.3% (314) were Spanish speaking, and 15.5% (72) were homeless. Mean blood pressure was reduced from 141.6 (SD 21.8)/85.1 (SD 13.2) to 132.1 (SD 17.3)/79.4 (SD10.8), a decrease of 9.5 (CI 7.4, 11.5)/5.7 (CI 4.4, 7.0) mmHg. Blood pressure was significantly reduced within the first month of treatment, and this reduction was sustained throughout the follow-up period. Using the National Health and Nutrition Examination Survey (NHANES) definition (<140/<90), blood pressure was controlled in 59.7% (296/496) of patients. No significant differences in control were noted based on gender, ethnicity, language, housing status, or clinic site.


CONCLUSIONS
SRFCs can provide effective long-term hypertension management and achieve rates of control that exceed national averages despite serving those least likely to be controlled.
