Effectiveness evaluation of a hypertension management program in a Federally Qualified Health Center (FQHC)

Abstract

The objective of this study was to examine effectiveness of a Hypertension Management Program (HMP) in a Federally Qualified Health Center (FQHC). From September 2018 through December 2019, we implemented HMP in seven clinics of an FQHC in rural South Carolina. A pre/post evaluation design estimated the association of HMP with hypertension control rates and systolic blood pressure using electronic health record data among 3,941 patients. A chi-square test estimated change in mean control rates in pre- and intervention periods. A multilevel multivariable logistic regression model estimated the incremental impact of HMP on odds of hypertension control. Results showed that 53.4% of patients had controlled hypertension pre-intervention (September 2016-September 2018); 57.3% had controlled hypertension at the end of the observed implementation period (September 2018-December 2019) (p < 0.01). Statistically significant increases in hypertension control rates were observed in six of seven clinics (p < 0.05). Odds of controlled hypertension were 1.21 times higher during the intervention period compared to pre-intervention (p < 0.0001). Findings can inform the replication of HMP in FQHCs and similar health care settings, which play a pivotal role in caring for patients with health and socioeconomic disparities.
