ABSTRACT
This study has been designed to evaluate the efficiency and coverage of the National Hypertension Prevention and Control program in predefined referral levels in Damavand district in Tehran. In this household survey 14 out of 27 health centers in Damavand were selected randomly and questionnaires completed for 400 persons aged 30 years or older who were selected systematically, in proportion to the size of the targeted population of each village. Coverage rate of screening program was 11.5% for men, 14.1% for women and 13% on the whole. Response rate to screening was 94%. Coverage of second, third and fourth referral levels was zero. Coverage of screening program was too low for modeling service utilization. The service has not been presented to the target population correctly and they were not aware of the service delivery. Program standards were not achieved completely. For program success, strict control is needed on the procedures of program implementation
