OBJECTIVES: The purpose of this study is to examine whether there is quality differences among AMI patients by severity of cases and by payers status.  METHODS: The Study examined the outcome differences of acute myocardial infarction (AMI) at the National Cardiovascular Center (NCC) Harapan Kita, Jakarta, Indonesia. This study analyzed medical records of patients with AMI during the period of January 1, 2009 until December 31, 2012.  RESULTS: The study found 5,472 patients with AMI consisting of 81.5% males and 18.5% females with the mean age of 56.3 years (range between 21-97 years vs. 26-96 years). Most of the patients were from Jakarta (51%). On severity levels, 46% patients were in severity level I, 47.7% severity level II, and 5.9% level III. More than half (54.6%) patients were treated with intervention (PTCA) or surgical procedures (CABG), while 44.4% patients were treated conventionally. We found that 43.7% of patients were covered by public insurance, and only 2.9% were on Medicaid. The average length of stays was 7.7 days and 87.8% were discharged in a good recovery. There was no difference in quality of treatment by difference payers or payment system although there was significant discrepancies in charges among difference payers.  CONCLUSIONS:  It is concluded that the doctors provided the same quality of services among AMI patients, regardless of payers’ status or charges. There was no difference in outcome of care among different payers.
