From morbidity reduction to cost-effectiveness: Enhanced recovery after surgery (ERAS) society recommendations in minimal invasive liver surgery

PURPOSE

Minimal-invasive liver surgery (MILS) reduces surgical trauma and is associated with fewer postoperative complications. To amplify these benefits, perioperative multimodal concepts like Enhanced Recovery after Surgery (ERAS), can play a crucial role. We aimed to evaluate the cost-effectiveness for MILS in an ERAS program, considering the necessary additional workforce and associated expenses.

METHODS

A prospective observational study comparing surgical approach in patients within an ERAS program compared to standard care from 2018-2022 at the Charité - Universitätsmedizin Berlin. Cost data were provided by the medical controlling office. ERAS items were applied according to the ERAS society recommendations.

RESULTS

537 patients underwent liver surgery (46% laparoscopic, 26% robotic assisted, 28% open surgery) and 487 were managed by the ERAS protocol. Implementation of ERAS reduced overall postoperative complications in the MILS group (18% vs. 32%, p = 0.048). Complications greater than Clavien-Dindo grade II incurred the highest costs (€ 31,093) compared to minor (€ 17,510) and no complications (€13,893; p < 0.001). In the event of major complications, profit margins were reduced by a median of € 6,640.

CONCLUSIONS

Embracing the ERAS society recommendations in liver surgery leads to a significant reduction of complications. This outcome justifies the higher cost associated with a well-structured ERAS protocol, as it effectively offsets the expenses of complications.

[Cost-efficiency of ascites treatment in the G-DRG system]

In Germany, around 1,000,000 people are affected by cirrhosis of the liver, with ascites being a common consequence. Hospitals are caught between the opposing aims of profitability and patient-centered treatment as a result of the increasing compression of services in hospitals and the increasing economization in the healthcare sector. Treatment costs are a crucial starting point for optimizing success and the optimal use of resources, given the restricted revenue flexibility due to established flat charges per case. The goal of this study is to examine the exact cost and income structures for ascites therapy at a university hospital that specializes in liver diseases. The treatment data of 778 patients admitted to the University Hospital Aachen's Department of Internal Medicine III between 2016 and 2019 were retrospectively and anonymously evaluated for this study. The revenue shares of the matrix of cost centers and cost types of the German Diagnosis-Related Groups (G-DRG) system were compared to the revenue shares of the specified services in the context of activity-based costing. Inadequate refinancing was discovered in every area of the therapy process that was investigated. As a result, the treatment of ascites in cirrhosis is currently underrepresented in the DRG system. This is owing to the fact that patients treated at the university hospital have a greater case severity.

The Effects of Anastomotic Leaks on the Net Revenue from Colon Surgery

Background: Complications in colon surgery can have severe health consequences, while at the same time, they are associated with increased costs. An anastomotic leak (AL) is associated with significantly increased costs compared to cases without. The aim of our analysis was to evaluate, which individual processes and patient-unrelated factors influencing the treatment process of colon surgery are responsible for the financial burden in patients with AL. Methods: Data from 263 patients who underwent colon surgery in Wetzikon hospital between January 2018 and December 2020 and was analyzed. In these 263 cases, 12 anastomotic leaks occurred and were compared with 36 cases without AL using a Propensity Score Matching (PSM). The covariates for the PSM have been Age, Sex, and Type of Surgery (t value: −3.26, p-value: 0.001). Results: A total of 48 surgeries were broken down in terms of costs and profitability. This reflected a mean deficit of −37,527 CHF per case (range from −130.05 to +755 CHF) for patients with AL, whereas a mean profit of 1590 CHF per case (range from −24.37 to +12.65 CHF) for those without AL (p < 0.001). Thus, the difference in profit showed a factor of 24.6 with an overall significant negative outcome for the occurrence of AL. The main cost contributing factors were the length of hospital stay (~p < 0.05) and length of intensive care (p < 0.05), whereas neither surgical operation time and anesthesia time nor surgical access, insurance status, indication or type of operation had a significant influence on the net revenue. Conclusion: AL after colon surgery leads to a significant deficit regarding the net revenue. Regarding process optimization, our analysis identified several sectors of non-patient-related, yet cost-influencing variables that should be addressed in future evaluations and optimization of the colon surgery treatment processes.

Impact of quality certification of multidisciplinary head and neck tumor centers

Background

Certification of multidisciplinary tumor centers is nowadays seen as the gold standard in modern oncological therapy for optimization and realization of guideline-based therapy and better outcomes. Single cases are reimbursed based on diagnosis-related groups (DRG). We aimed to review efficiency, cost analysis, and profitability following a certification.

Methods

Tumor board certification at the university hospital Aachen was implemented in 2013. We compared 1251 cases of oropharyngeal cancer treated from 2008 to 2017 before and after certification. For this purpose, several patient characteristics, surgery, and stay-related constants, as well as expenses and reimbursement heights were analyzed statistically.

Results

Following certification, the total case and patient number, surgery duration, hours of mechanical ventilation, case mix index points, DRG reimbursements as well as the costs increased significantly, whereas days of intensive care unit, amount of blood transfusions, patient clinical complexity level (PCCL) and the overall stay were significantly lowered. No changes were observed for the patient’s age and gender distribution. Also, the predetermined stay duration stayed constant.

Conclusions

Certification of head-neck tumor centers causes a concentration of more complex cases requiring higher surgical efforts, which can be processed more efficiently due to a higher level of professionalism. Despite their benefits in cancer care, without compensation, centers may be struggling to cover their expenses in a system, which continuously underestimates them.
