Objective To explore a model of day care fitting the local and regional characteristics to serve all the ethnic groups in Xinjiang, and analyze its performance. Methods Such indicators as the outpatient visits, discharges, average days of stay, and preoperative bed-occupying days of the hospital from 2010 to 2015 before the day-care mode was in place, were selected and compared against those since the mode in place from 2016 to 2018.Also compared were six typical diseases common for day surgery in day surgery wards sent from various departments, with non-day-surgery patients of the same period before.The comparison covered such indicators as nursing cost, laboratory examination cost, treatment cost, drug cost, consumables cost, drug cost ratio and average hospitalization cost between the two modes. The data were subject to statistical analysis using t test and χ2 test.Results Since day care mode in place, the average days of stay(8.93 days vs.7.72 days)and preoperative bed-occupying days(3.50 days vs.3.01 days) both decreased significantly, given the gradual growth of outpatients and discharges. Average hospitalization expenses of the six groups dropped significantly as well( P<0.05).Conclusions Day care mode can not only enhance the utilization of hospital beds to add to the income structure positively, but also significantly reduce the patients′hospitalization expenses, thus improving patient experience and satisfaction.
