OBJECTIVES: To assess the correlation among Pre-operative Condition, Waiting Time and Post-operative Outcome (mortality and morbidity) in Elective Patients registered in the waiting list of CABG cases in Harapan Kita Hospital 2011. METHODS: The study used quantitative method with retrospective design, combined by qualitative method by doing indepth interview, observation and document review. Samples for quantitative method are those who experienced CABG since January until September 2011 (252 patients), and the operations were not categorized as the emergency ones. RESULTS: The study results showed that out of 4 pre-operative conditions, only stenosis left mainwhich has significant correlation with waiting time. The composit of overall risk-score had no significant correlation with both waiting time and post-operative outcome (mortality and morbidity). In addition, there is no significant correlation between waiting time and outcome. This study also found that there is no waiting time management system which is based on the patients’ pre-operative condition. Other findings are: lack of operating room, lack of beds in ICU, limited heart surgeons, to many patients register for CABG in this hospital, and individual system (not teamwork system) which is applied in managing the surgeons. These findings lead to quite long waiting time (25 days) for CABG patients to be operated. CONCLUSIONS: This study suggests to Heart Surgery Unit to combine between individual and teamwork or collective system, to develop information system which is based on patients' pre-operative conditions in determining schedule of surgery/operation. Suggestion also goes to Hospital Director, in order to increase the number of operating rooms, beds in ICU, heart surgeons, nurses. Finally this study suggest to the Ministry of Health to develop or build capacity of several other hospitals located in Jakarta or outside Jakarta to become heart centers.
