Factors impact the cost differences between INA-CBGs tariffs and hospital costs in JKN patients with appendicitis cases.

Abstract Objective To identify the factors which affect the cost difference in appendicitis cases. Method This was an observational analytic research with cross-sectional study design. This research involved 40 medical records of patients who were diagnosed with appendicitis in Jombang Islamic Hospital from January-December 2018. The patients were selected using stratified random sampling. The data were analysed using linear regression. Results This research showed that length of stay (β = 0.290; p = 0.005) and schedule for the surgery (β = 0.265; p = 0.010) had a significant impact on the cost differences in the JKN patient with appendicitis. An increase in the length of stay and the delay of the surgery schedule will increase the cost difference. Conclusion The hospital should monitor the surgeon's compliance with the length of stay of appendicitis cases. The schedule for the surgery also needs to be followed to prevent the delay from reducing the cost difference in Jombang Islamic Hospital.
