Background: Accurate blood pressure measurement has more importance in diagnosis, assessment of cardiovascular risk and efficacy of antihypertensive agents in hypertensive patients. Objectives: Present study was designed for sphygmomanometers accuracy assessment in two study hospitals. Results: Among sphygmomanometers, 25 (39.6%) devices had excluded due to physical defects. Air leak (15.9%) was most cause of sphygmomanometers exclusion from the study. According study accuracy determination method, among 38 sphygmomanometers, 21 (55.27%) devices were inaccurate and 17 (44.82%) devices were accurate. All of three mercury sphygmomanometers were accurate. Mean of errors in included sphygmomanometers was 4.98 mmhg and 34.2% of included sphygmomanometers in one point accuracy determination had more than 10 mmhg differences with standard sphygmomanometer. Conclusions: Current devices in our health care centers were inaccurate in most cases and might report wrong number as patients’ blood pressure.
