Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

Overview: This study uses communications strategies delivered through the traditional emergency medical response system to increase the proportion of low-income adults who obtain blood pressure screening and follow-up information for hypertension treatment options. The project will test the effectiveness of source personalization and tailored messaging in motivating potentially high-risk people, identified by 911 responders, to come to a local fire station for hypertension screening. Specific Aims: The specific aims are: 1. Test the effectiveness of three health marketing approaches to motivate high-risk people, identified via 911 responders, to come to a local fire station for hypertension screening. The mailed marketing approaches vary personalized risk information and personalization of source. 2. Test the effectiveness of two mailing interventions (blood pressure kits with and without promotional gifts) to increase blood pressure monitoring among patients who have come to a fire station for a second blood pressure check.
