Abstract：Objective To evaluate the effect of bed allocation by using diagnosis related groups. Methods Data from inpatient medical record front sheet of 76 852 patients in 2018 were analyzed, and groups were divided according to whether to accept the allocation of beds. The ability, efficiency and safety of treatment were described in the two groups. The t-test was used to compare the difference of case weight, average length of stay and average cost per time between groups and chi-square test was used to compare the difference of case fatality rate among different risk groups. Results Twenty-three major disease categories and 305 diagnosis related groups were detected in the group with bed allocation. Comparing to the non-bed allocation group, among the top 10 diagnosis related groups of hospital admissions, 5 diagnosis related groups including BR23, FM49, BR21, ES13 and ES15 had lower average length of stay and average cost, which were statistically significant (P<0.05). ET13 in the group with bed allocation had lower average cost (P<0.001) while GU15 had higher average cost (P=0.047) than that in the non-bed allocation group. Case-mix index was higher (CMI=1.25, P=0.009) and the mortality of medium-high risk and high risk group was lower in the group with bed allocation (mortality was 1.0%, P=0.047) than that in the non-bed allocation group. Conclusion The hospital bed allocation can increase the capacity and efficiency of admission. The allocation of beds can improve the capacity and efficiency of treatment, and at the same time include safety, and achieve good results.
