Analysis of economic impact of laparoscopic liver resection according to surgical difficulty.

INTRODUCTION: The advantages of laparoscopic liver resection (LLR) are well known, but their financial costs are poorly evaluated. The aim of this study was to analyze the economic impact of surgical difficulty on LLR costs, and to identify clinical factors that most affect global charges. METHODS: All patients who underwent LLR from 2014 to 2018 in a single French center were included. The IMM classification was used to stratify surgical difficulty, from group I through group III. The costing method was done combining top-down and bottom-up approaches. A multivariate analysis was performed in order to identify clinical factors that most affect global charges. RESULTS: Two hundred seventy patients were included (Group I: n = 136 (50%), Group II: n = 60 (22%), Group III: n = 74 (28%)). Total expenses significantly increased (p < 0.001) from Group I to Group III, but there was no difference regarding financial income (p = 0.133). Technical platform expenses significantly increased (p < 0.001) from Group I to Group III and represented the main expense among all costs with a total of 4 930 ± 2 601€. Among technical platform expenses, the anesthesia platform represented the main expense. In multivariate analysis, the four clinical factors that affected global charges in the whole study population were operating time (p < 0.001), length of stay (p < 0.001), admission in ICU (p < 0.001) and the occurrence of major complication (p < 0.05). An admission in ICU was the clinical factor that affected most global charges, as an ICU stay had a 39.1% increase effect on global charges in the whole study population. CONCLUSION: LLR is a cost-effective procedure. The more complex is the LLR, the higher is the hospital cost. An admission in ICU was the clinical factor that most affected global charges.

Enhanced recovery protocols in colonic surgery: retrospective cohort analysis of economic impact from an institutional point of view.

BACKGROUND: Despite increasing evidence supporting the beneficial effects of enhanced recovery protocols (ERPs), their accurate economic impact on institutions remains lacking. The aim of this study was to analyze ERP economic impact in a French center in order to further encourage implementation. METHODS: All patients who underwent elective laparoscopic right or left colectomy for benign or malignant pathology from 2014 to 2017 in a single center were retrospectively reviewed. ERP according to national recommendations was effective starting November 2015. Perioperative data and all direct costs borne by the institution were collected for each patient. Patients who underwent colectomy before and after ERP implementation were compared. RESULTS: Overall, 288 patients were included of which 144 received conventional perioperative care (CC) and 144 received ERP. There were 161 (56%) men, median age was 71 (28-92) years, and 242 (84%) patients underwent surgery for malignant disease. Operative time, intraoperative blood loss, and severe postoperative complications were similar between both groups. ERP was associated with reduced Clavien-Dindo I-II postoperative complications (15% vs. 28%, p = 0.010) and overall in-hospital stay (6 vs. 7 days, p = 0.003). Overall institutional costs were lower in the ERP group although difference was not statistically significant (7022 vs. 7501 euros, p = 0.098). Estimated savings per patient reached a mean of 480 euros. CONCLUSIONS: In a tertiary French center, ERP was associated with reduced postoperative morbidity and in-hospital stay resulting in considerable cost savings. Although not significant, ERP resulted in positive economic impact even in an early implementation phase.
