Background: Investigating the conditions and the appropriateness of admission of patients in hospitals is an important issue which can improve the efficiency of health care delivery. Intensive care unit (ICU) is important due to applying expensive financial sources; therefore, its efficient application is of great priority. In this regard, the current study aimed to determine the financial burden of inappropriate admissions in internal intensive care units (IICUs). Methods: It was a cross-sectional study conducted in 2014. A total of 294 patients admitted to IICUs of Shahid Faghihi and Nemazee hospitals of Shiraz, Iran, in 2012 were enrolled into this retrospective study. The study was conducted in two phases, using the guidelines of American critical care association (ACCA) and experts' opinion to investigate the financial burden of inappropriate admissions in IICUs of the above-mentioned hospitals.
Results:The results showed no statistically significant relationships among insurance status, insurance type, age, gender and inappropriate admission by applying Chi-square. Among 294 admitted patients under the study, the inappropriate admissions were 11.2% based on the guidelines and 13.6% based on the experts' opinion. The level of agreement of the guidelines and experts' opinion for the inappropriate admissions was 0.076 based on Kappa coefficient. The total financial burden imposed on the insurance agencies and the patients by inappropriate admissions was US$ 47867.78 based on the guidelines and US$ 83241.68 based on the experts' opinion. Conclusions: Inappropriate admissions to ICUs may impose additional costs to the health system and the patients on one hand, and deprives other patients from receiving health services. Therefore, it is crucial to effectively plan for the application of ICU beds.
