Nurse-led coordinated surgical care pathways for cost optimization of robotic-assisted partial nephrectomy: medico-economic analysis of the UroCCR-25 AMBU-REIN study.

PURPOSE: Robot-assisted partial nephrectomy (RAPN) reduces morbidity, enabling development of Enhanced Recovery After Surgery (ERAS) and day-case protocols. Additional financial costs limit its integration into clinical practice. We evaluated the medico-economic impact of RAPN using a nurse-led coordinated pathway of care (NLC-RAPN). METHODS: All tumor RAPNs performed in 2017 were prospectively included in nurse-led protocols: NP-RAAC (ERAS) or Ambu-Rein (day case). Clinico-biological and pathological data were prospectively collected within the French Research Network for Kidney Cancer database (NCT03293563). Estimated costs were compared to "average" patients at the national level operated by open partial nephrectomy (OPN) or RAPN, using data from the 2017 French hospital discharge database and the national cost scale. RESULTS: The NLC-RAPN cohort (n = 151) included 27 (18%) outpatients and the average hospital length of stay (LOS) was 2.4 days. In the national control cohorts for OPN (n = 2475) and RAPN (n = 3529), the average LOS were 8.0 and 5.2 days, respectively. The mean incomes per group were €7607 for NLC-RAPN, €9813 for OPN, and €8215 for RAPN. The mean daily cost of stay was €659 for NLC-RAPN, €838 for OPN, and €725 for RAPN. The overall cost for NLC-RAPN was €6594, €8733 for OPN, and €8763 for RAPN. The best operational margin was obtained for day-case NLC-RAPN (€1967). CONCLUSION: Combining RAPN with nurse-led coordinated pathways of care led to a shorter hospital stay and reduced costs versus OPN. This may facilitate the economic sustainability of robotic assistance for hospitals where the extra cost is not covered by the healthcare system.

Rational testing for gene fusion in colorectal cancer: MSI and RAS-BRAF wild-type metastatic colorectal cancer as target population for systematic screening.

Gene fusions provide access to new therapeutic opportunities for patients treated for a colorectal cancer (CRC). However, they do not excess 1% of patients. A better identification of patients in whom gene fusions are highly prevalent is a major issue in a therapeutic and medico-economics perspective. This study assesses the rates of gene fusions in CRC patients with MSI/RAS-BRAFWT in our routine practice detected with a commercially available NGS-based fusion panel. Among the 130 MSI CRC tumors, 43 (33%) were KRAS-NRAS-BRAFWT. A gene fusion was detected in 7 (25.9%) of the 27 MSI/RAS-BRAFWT samples, which had RNA suitable for analysis after quality control. These fusions involved mainly NTRK1/3 (n = 5), as well as ALK (n = 1) and BRAF (n = 1). In the present study, we confirm that patients with MSI/RAS-BRAFWT CRCs represent a subpopulation in which targetable gene fusions are overrepresented. Our results support the use of a two-step algorithm for molecular screening, in which metastatic CRC patients would have routine MSI and RAS/BRAF testing, and then only those with MSI/RAS-BRAFWT would be screened with dedicated NGS RNA panel for gene fusions.

Indirect calorimetry: The 6 main issues.

BACKGROUND AND AIMS: Optimal nutritional therapy, including the individually adapted provision of energy, is associated with better clinical outcomes. Indirect calorimetry is the best tool to measure and monitor energy expenditure and hence optimize the energy prescription. Similarly to other medical techniques, indications and contra-indications must be acknowledged to optimise the use of indirect calorimetry in clinical routine. Measurements should be repeated to enable adaptation to the clinical evolution, as energy expenditure may change substantially. This review aims at providing clinicians with the knowledge to routinely use indirect calorimetry and interpret the results. METHOD: We performed a bibliographic research of publications referenced in PubMed using the following terms: "indirect calorimetry", "energy expenditure", "resting energy expenditure", "VCO2", "VO2", "nutritional therapy". We included mainly studies published in the last ten years, related to indirect calorimetry principles, innovations, patient's benefits, clinical use in practice and medico-economic aspects. RESULTS: We have gathered the knowledge required for routine use of indirect calorimetry in clinical practice and interpretation of the results. A few clinical cases illustrate the decision-making process around its application for prescription, and individual optimisation of nutritional therapy. We also describe the latest technical innovations and the results of tailoring nutrition therapy according to the measured energy expenditure in medico-economic benefits. CONCLUSION: The routine use of indirect calorimetry should be encouraged as a strategy to optimize nutrition care.

[Split-thickness skin graft donor site: which dressing use?]. / Site donneur de greffe de peau mince : quel pansement utiliser ?

INTRODUCTION: The management of split-thickness skin graft donor sites is targeted towards promoting the healing process, reducing pain. This has been an inconclusive topic. The aim of this study was to list and to discuss the French practices in term of split-thickness skin graft (STSG) donor site dressing. MATERIALS AND METHODS: Multicentric national study by questionnaire (Google Drive(®)) for the attention of the plastic and/or pediatric surgeons. The type of dressing used on skin and sclap and the rhythm of dressing changes were analyzed. RESULTS: The study included 26 surgical centers on 40 contacted. The alginate is mainly used (Algostéril(®)) (17/26). It is left in position until healing (13/17). Five other types of dressings have been reported: paraffin gauze (3/26), lipidocolloides (1/26), Mepitel(®) (1/26), Mepilex(®) (1/26), indifferent use of gauze or alginate dressings (4/26). Twenty-two out of 26 centers make no difference in dressing choice between skin and scalp. Medical practices did not differ between adult or pediatric departments. CONCLUSION: Cost-effectiveness has become an important issue in wound management, requiring judicious use. The lack of consensus regarding split-thickness skin graft donor site dressing and our clinical practices force us to reconsider the best therapeutic option. This study coupled with the analysis of the literature highlights the difficulties of the practitioner in choosing the best dressing. The alginate seems to get the preference of our practices by its ease of use, its absence of change (reduces pain by limiting manipulations) and its moderate cost.

[About laryngeal mask: is the lowest price material the better cost-efficacy choice?]. / Comparaison de quatre masques laryngés à usage unique pour la chirurgie carcinologique du sein: une approche médico-économique.

OBJECTIVE: The main goal of this study was to achieve a medico-economic comparison between four disposable laryngeal masks (LM) (LMA-Unique™, Ambu AuraOnce™, I-Gel™ and LMA-Suprême™). STUDY DESIGN: A prospective, randomized, monocentre study. MATERIAL AND METHODS: In a center, using routinely LMA-Unique masks, scheduled breast surgery patients were allocated into four groups according to the LM model. After the induction, the modalities of use were collected, as well as the intraoperative events that required additional anesthetic equipment. The real cost of each model was calculated (cost of the mask+extra cost related to complications). Using the LMA-Unique as a reference, we performed a cost-efficacy analysis. We realized a cost-efficiency analysis putting in parallel the impact on the cost and the incidence of the events. RESULTS: A total of 178 patients were included. According to the cost-efficacy analysis, the dominant model was the Ambu AuraOnce™ (Δreal cost: -34.2%, Δevents: -30.6%). The LMA-Unique™ was dominated because of a high morbidity rate. The I-Gel™ and LMA-Suprême™ models were more efficient but more expensive (Δreal cost: +16% and +22.5% respectively). To compensate for additional costs, it would be necessary to apply a price reduction of at least 50%. CONCLUSIONS: Despite their better efficiency and safety, the latest generation laryngeal masks are still expensive in spite of a low rate of complication. These results do not take into account very rare and severe complications not met in this study in the limited size; then the economic and medical impact can influence the choice beyond the simple analysis cost-efficiency.
