Two interventions were studied, both of which improved upon existing activities and strengthened the relationship between community and clinic-based hypertension control activities. The first intervention improved the identification and entry into care of new and uncontrolled hypertensives in the community with an emphasis on bringing more young males (especially African American) through: (a) screening and education activities (b) a microcomputer-based client tracking system to follow persons with elevated blood pressure (c) an outreach system to improve follow-up into clinical care.
