Objective To establish a multi-regression workload model based on surgical related factors.Methods The routine surgery workload was measured by the RBRVS development process of Hsiao WC,and multiple regression models were established for the operative factors from the surgical project specifications,pricing regulations and the operative workload.Results Top workload factors of an operation were technical difficulty,surgical classification and time cost.Multiple regression equation R2=0.699.One degree increase of technical difficulty would push up workload by 0.034;one level of operation grade would raise workload by 0.793;and every one hour longer of the operation time would increase workload by 1.025. Conclusions Operations of higher level, technical difficulty and longer time cost should deserve more reimbursement in consideration of both pricing and income distribution.

OBJECTIVE To evaluate the therapeutic efficacy and safety of vonoprazan-based triple therapy in treatment-naive patients with Helicobacter pylori （Hp） infection. METHODS From March 2022 to August 2023， 198 treatment-naive patients with Hp infection treated at the outpatient service of department of gastroenterology in our hospital were assigned to the vonoprazan- based triple therapy group （VAC group， n＝98） and the bismuth-based quadruple therapy group （BQT group， n＝100） using the random number table method. Patients in VAC group were given Vonoprazan fumarate tablets （20 mg） + Amoxicillin capsules （1 g） + Clarithromycin tablets （0.5 g）， all twice daily. Patients in BQT group were given Esomeprazole magnesium enteric-coated tablets （20 mg， twice daily） + Metronidazole tablets （0.4 g， four times daily） + Tetracycline tablets （0.5 g， three times daily） + Bismuth potassium citrate capsules （0.6 g， twice daily）. The treatment course for both groups was 14 days. The Hp eradication rates were compared between the two groups in intention-to-treat （ITT）， modified intention-to-treat （MITT）， and per-protocol （PP） analysis sets， while adverse reaction occurrence and medication compliance of two groups were recorded. RESULTS In the ITT， MITT and PP analyses sets， the Hp eradication rates in VAC group were non-inferior to those in BQT group. The incidences of grades 1-2 nausea， vomiting， and loss of appetite in VAC group were significantly lower than in BQT group， and the proportion of patients with good compliance was significantly higher in VAC group （P＜0.05）. Regardless of whether the body mass index （BMI） ≤25 kg/m2 or ＞25 kg/m2， no statistically significant difference was observed in the Hp eradication rates between the two groups （P＞0.05）. CONCLUSIONS Vonoprazan-based triple therapy is non-inferior to bismuth-based quadruple therapy in the treatment of treatment-naive patients with Hp infection， with higher safety and good patient medication compliance. BMI has no significant impact on the Hp eradication rate.
