[Quality indicators of hospital care: evaluation of patient care in acute myocardial infarction].
In the international hospital accreditation programs there is an increasing emphasis on involving performance indicators. The inpatient mortality rate of AMI patients and the usage of thrombolytic therapy are very common, evidence based indicators of these programs. The authors goal was to analyze the applicability of these indicators in the evaluation of the Hungarian hospital care. In Hungary, there is a data collection system on every inpatient case. This database was used to determine the above mentioned two indicators for 1997 and 1998. They calculated by hospital group level, by institutions and by geographic areas crude rates and rates adjusted for age and gender, and for severity using the different DRGs of AMI patients. In these two years the inpatient mortality rates of AMI patients were 20.4% and 21.7%, and the usage of thrombolytic therapy were 9.9% and 11.8%, respectively. Using indirect standardization methodology in the usage of thrombolytic therapy, they found high differences among the counties compared to the national average, the range was 51-199%, and among the institutions 0-306%, respectively. It is clear, that there are huge differences in the curative processes and in the inpatient mortality rates of AMI patients among the hospitals. The differences are developed by chance, there are no close connections either to hospital groups, or to geographical locations. Because of the difficulties of risk adjustment, they suggested that indicators were suitable for benchmarking. It is necessary to implement in the national quality criteria system different indicators for evaluating the patient care, to develop programs for auditing the best and worst hospitals and to introduce standards for assuring the validity of the basic data.
