Research on 1 282 cases of per-hospitalization high inpatient expenditure: influencing factors

Abstract

Objective To explore the causes of per-hospitalization high inpatient expenditure of a tertiary hospital in 2015, by analyzing the influencing factors. Methods We retrospectively studied 1 282 inpatient cases who cost more than 100 000 yuan per case at a tertiary hospital in 2015, analyzing statistically major influencing factors of such expenditure in variance analysis and multiple stepwise regression analysis. Results The average days of stay of these cases were 27.6 days, and the average medical cost of those cases was 149 153 yuan per person. Costs for medicines and material made up a large proportion of medical costs, respectively accounting for 33.38% and 31.98% of the total. The days of stay, prognosis of the patient, complications as well as hospital infection, surgeries, gender of the patients constituted major factors on inpatient medical expenditure. Conclusions Reducing the average days of stay, guiding reasonable applications of drugs and medical materials, strengthening management on operations and controlling excessive medical services are effective approaches to reducing excessive growth of medical costs.
