There are four situations in the use of Hospital Information Technology applications or better known as SIMRS in Indonesian hospitals, first, the hospital has not had SIMRS yet, second, the hospital already has SIMRS but it has not been integrated, third, the hospital has an integrated SIMRS based on non-web service but has not bridged with E-claim application, and fourth, the hospital already has SIMRS based on Web Services and bridged with INA-CBG's E-Claim Application. The purpose of this study was to determine the effectiveness of the National Health Insurance (JKN) Inpatient Claim using an integrated SIMRS web-based (Bridging System) with the INA-CBG'S E-Claim application Version 5.2 at IbnuSina Hospital Indrapuri Aceh Besar. This research was a quantitative type with a cross sectional design. The sampling in this study was using the Simple Random Sampling technique with a total sample of 368 medical records inpatient medical records at IbnuSina Hospital. The research instrument used was observation using a checklist and a stopwatch. The data were analyzed using Mann Whithney statistical test and logistic regression. The results of the bivariate analysis showed that there was a significant difference in the effectiveness variable (p=0.001), Data Input Time (p=0.001), Data Accuracy (p=0.001), Completeness of Medical Record Data (p=0.001) and unclear medical record writing (p=0.001). Furthermore, the results of multivariate analysis showed that the variable that most influenced the level of effectiveness of claiming activities was the variable of completeness of medical record data (p-value <0.05). Based on the results of this study, it is hoped that the IbnuSina Hospital should immediately carry out Electronic Medical Record (ERM) so as to reduce the incidence of inaccuracy, incomplete RM, and Unclear Medical Record Writing.
