[The use of a check list for quality assurance of the treatment of acute myocardial infarction in the coronary care unit].
The implementation of Quality Assurance programs for the treatment of acute myocardial infarction in the Cardiac Intensive Care Unit may be specially important. In fact several therapeutic options are available in these patients, and delay in treatment must be as short as possible. A Quality Assurance program has been started in our center with a registry of all patients admitted within 24 hours of onset of acute myocardial infarction.


METHODS
The following data were recorded: 1) indicators of Organization: pathway to admission, pre-hospital and in-hospital delay; 2) Process Indicators: duration of hospital stay, initial choice of therapy (conservative, intravenous lysis, primary angioplasty), and further diagnostic and interventional procedures; 3) Outcome Indicators: mortality and complications during admission, and 6-12 months follow-up.


RESULTS
Since february 1994 to August 1995, 211 consecutive patients were included in the registry; 156 were male, mean age 66 years. Mean pre-hospital delay was 286 minutes. Admission was decided by a physician in 99 cases and by the patient him/herself in 112 cases; pre-hospital delay was 390 min. In the former group, and 194 min. In the latter (p < .001). Mean in-hospital delay was 61 minutes. Conservative treatment, intravenous lysis, and primary angioplasty were chosen by the attending cardiologist in 89 patients (group A), 69 patients (group B), and 53 patients (group C) respectively. The latter group included patients with highest risk on the basis of clinical and electrocardiographic characteristics. In-hospital mortality was 17, 7 and 9% In the 3 groups, respectively. An echocardiogram and coronary angiography were performed before discharge in 81% and 57% of patients, respectively. The mean duration of hospital stay was 11 days, irrespective of the initial therapeutic choice.


CONCLUSIONS
A registry for patients with acute myocardial infarction provides information which is essential in the evaluation of therapeutic protocols; it may also help in improving the cooperation between the Emergency Department, the attending cardiologists, and the family physicians.
