QUALITY OF CORONARY EVENT AND ACUTE CORONARY CARE REGISTRATION IN A UNIVERSITY AFFILIATED HOSPITAL (2003-4)

Background: Assessing the trend of ischemic heart diseases and the process of acute coronary care is one of the most important tools in monitoring the programs dedicated to control of ischemic diseases. The current project was developed to assess the feasibility of using routine data registered in clinical records for coronary event registration according to the standards of WHO/MONICA project . Methods: Hospital records of 320 cases with primary diagnosis of acute coronary syndrome (80 cases from each quarter, July 2003-4) were evaluated according to sufficiency of data. Data were evaluated according to "internal consistency", "change in the proportion of missing data in the time periods" and "the proportion of insufficient data". Results: Available data of hospital records were not sufficient to determine the diagnosis in 0.7% of cases; In addition, they were resulted in a probable diagnosis in 11.2% of coronary events. Median percents of missing data regarding the prescribed drugs before event was more than 10% in both fatal and non-fatal coronary events (score 1 of 4). Median percents of missing data regarding the ECGs, cardiac enzymes and cardiac resuscitation was lower than 5% in non-fatal coronary events and lower than 2% in fatal cases (scores 2 and 3 of 4 relatively). Conclusion: The quality of available registered data in the evaluated clinical records was comparable with many reporting units of MONICA project. Using the available clinical records seems to be effective and feasible for systematic registration of cardiac events.
