Methods: We evaluated the effectiveness of a compulsory data field in a computerized medical record (CMR) in improving blood pressure (BP) screening.
Results: The proportion of study patients who had their BP measured increased from 40.6% to 58.5% (P < 0.001) after the intervention. After adjusting for age, gender and number of visits, patients were 73% more likely to have their BP recorded after the introduction of the compulsory field.
