Abstract 1347: Efficacy of a Brief Intervention: Blood Pressure “Zones” Assessment Card and Educational Encounter With a Healthcare Provider and Reduction of Hypertension
Introduction: CDC data indicates that 30.3% of women in the United States have hypertension. Healthy People 2010 aims to reduce the incidence of hypertension to 25%.
Hypothesis: Blood pressure (BP) screening in combination with a healthcare provider directed educational encounter and BP log card given to the patient can be an effective tool for motivating behavior change and reducing hypertension in Kentucky women.
Methods: A BP log and medical/medication history wallet card was designed to identify normal, elevated and hypertensive blood pressures indicated by a green, yellow or red zone. Greater than 200 providers in 47 offices/organizations in northern Kentucky were trained (with protocol and scripting) to facilitate a 1 to 2 minute educational encounter. BP was taken and documented for the patient, who was instructed to keep the log as a wallet card/portable medical record. Providers submitted data on the numbers of patients screened, BP ranges, patient knowledge, anti-hypertensive use, lifestyle modifications (“taking action”), and referrals on a monthly basis through an online database.
Results: Between January 1 and December 31, 2008, 19,631 women experienced the BP educational encounter and 35.6% (n=6,998) newly screened women had elevated BP. Following the encounter, 92.3% of women reported understanding their BP value. Of returning patients, 54.8% (n=2,496) had documented improved BP, with 18.4% of women measuring 120/80 mm Hg or less and with only 5.2% of patients reporting that they had been started on BP medication. Over half of the women (52.1%) reported that they were “taking action” to reduce their BP. Following the encounter, 31.2% of patients were referred to primary care and 49.1% were referred for holistic services (smoking cessation or stress management).
Conclusions: The BP educational encounter is an inexpensive and effective tool for motivating change in women in Kentucky. Following the encounter, more than half of patients reported taking action by making lifestyle changes and a concordant percentage demonstrated reduced BP. This study demonstrates the efficacy of a color-coded BP card and brief educational encounter in motivating individuals with hypertension to make lifestyle modifications for blood pressure reduction.
