Objective To investigate the variation of total hospitalization cost for single-diagnosed disease of different types of acute appendicitis in a three-A hospital, so as to provide evidence for the reimbursement amount of social medical insurance. Methods All patients with acute appendicitis who had surgery treatment during January-April 2011 (before implementing the fee system for single-diagnosed disease) and January-April 2012 (after implementing the fee system for single-diagnosed disease) were collected in this study for analysis. According to the types of acute appendicitis, the patients were stratified into the low risk group (simple, suppurative and gangrenous) and the high risk group (perforative, abscess-formed and pregnancy-combined). The correlation between total hospitalization cost and types of acute appendicitis, as well as the changes of total hospitalization cost after implementing the fee system for single-diagnosed disease were analyzed. Results A total of 90 eligible patients were included. The disease types were positively correlated with hospital stays and total hospitalization cost. All three types in the low risk group could control the average total hospitalization cost within RMB 10 000 yuan. The results of sensitivity analysis showed that, before implementing the fee system for single-diagnosed disease, the total hospitalization cost up to RMB 6 000 yuan could be positively correlated with the above risk stratification (r=0.442, P=0.003). After implementing the fee system for single-diagnosed disease from January to April 2012, the constituent ratio of hospital stays, compared with that in the same period of 2011, had no significant difference (P=0.108) between the two groups; but the ratio of hospital stays (less than 5 days) increased from 45% to 64%, and the ratio of hospital stays (greater than or equal to 10 days) decreased from 17% to 4%, indicating a tendency of shortening hospital stays. Also, the constituent ratio of total hospitalization cost had no significant difference (P=0.114) between the two groups; but the ratio of total hospitalization cost (greater than or equal to RMB 9 000 yuan) decreased from 32% to 13%, indicating a tendency of lowering total hospitalization cost. Conclusion The low risk group of acute appendicitis, RMB 6 000 yuan should be rated as the rational reimbursement amount of social medical insurance. The total hospitalization cost for the high risk group is quite various, so the further studies are needed to investigate the feasibility of the fee system for single-diagnosed disease as well as the rating amount of total hospitalization cost. The implementation of the fee system for single-diagnosed disease is helpful to shorten hospital stays and reduce total hospitalization cost.
ObjectiveTo compare the cost changes of total knee arthroplasty (TKA) before and after the cancellation of medical consumables addition, so as to provide reference for the national medical reform policy.MethodsThe patients treated with TKA between September 2018 and February 2019 were admitted as objects of study, and 372 of them met the selection criteria and were finally included in the study. According to the time node of cancelling the medical consumables addition (December 24, 2018), all patients were allocated to pre-cancelling and post-cancelling groups (n=186). The clinical data of patients (gender, age, length of stay, disease classification), and various treatment costs (the costs of diagnosis and treatment, examination, laboratory, material, anesthesia, bed, nursing, operation, drug, and others) were collected. And the changes of various costs and proportions before and after cancelling the medical consumables addition were compared.ResultsThere was no significant difference in gender, age, and disease classification between the two groups (P>0.05); the length of stay after cancelling the medical consumables addition was significantly longer than that before cancelling (t=2.114, P=0.035). There was no significant difference in the total cost of TKA before and after cancelling the medical consumables addition (t=0.214, P=0.831). Compared with that before cancelling the medical consumables addition, the cost of material was significantly reduced, and the costs of diagnosis and treatment, anesthesia, nursing, and operation were significantly increased (P<0.05); the costs of examination, laboratory , bed, drug, and others were basically stable, and the differences were not significant (P>0.05).ConclusionThe total cost of TKA is stable, the proportion of material cost is significantly reduced, the proportion of diagnosis and treatment cost reflecting the technical content of medical staff is significantly increased, which is in line with the expectation of the national policy of cancelling the medical consumables addition.
