[Climate crisis and carbon-neutral anesthesia]. / Urgence climatique et anesthésie carboneutre.

In the context of climate crisis, health care systems need to reduce their own carbon footprint. An accumulating amount of data shows how anesthesia can drastically reduce direct emissions of powerful greenhouse gases (GHG), like inhaled volatile anesthetics and nitrous oxyde (N2O). This synthesis exposes why anesthesia is a carbon hotspot and how practical strategies can reduce direct GHG emissions without compromising quality of care.

Dans le contexte de la crise climatique, les systèmes de santé doivent se mobiliser pour diminuer leur propre empreinte carbone. Les évidences actuelles mettent en lumière les progrès qui peuvent être faits dans des domaines émettant directement des gaz à effet de serre (GES) comme en anesthésie, utilisant des gaz halogénés et du protoxyde d'azote (N2O), puissants GES. Cet article synthétise la problématique des émissions de GES directes en anesthésie et l'impact de quatre stratégies durables et concrètes pouvant être instaurées dans nos institutions pour réduire considérablement ces GES, sans compromis pour la qualité des soins.

A Medicoeconomic Evaluation of a Telehealth Platform for Elective Outpatient Surgeries: Protocol for a Randomized Controlled Trial.

BACKGROUND: The number of elective outpatient surgeries in Canada has increased markedly in the last 10 years. However, unanticipated cancellations on the day of surgery and adverse postoperative events are frequent. Modern technologies have been shown to be of great help in the medical field in improving patient care. Thus, it is likely that dedicated technologies could also significantly improve surgical outpatients' pathways. Therefore, the department of anesthesiology at the University of Montreal Medical Center, in collaboration with LeoMed, a telemedicine platform, has developed a telehealth solution to offer more efficient perioperative support and follow-up for patients undergoing ambulatory surgery. OBJECTIVE: The objective is to evaluate the medicoeconomic benefit of a dedicated perioperative telehealth platform for patients undergoing day surgery. Our hypothesis is that this dedicated telecare solution will allow more efficient patient care, which will reduce all types of medical costs related to day surgery pathways. METHODS: This study is a single-center, single-blinded, 2-group randomized controlled trial. One thousand patients aged over 18 years with internet access who are scheduled to undergo ambulatory surgery will be enrolled and randomized either to follow a perioperative path that includes a patient-tailored perioperative digital app via the LeoMed telecare platform for 1 month or to follow the standard of care, which does not offer personalized digital support. The primary outcome will be to evaluate the cost-effectiveness of the telecare platform, assessing direct costs from factors such as unanticipated cancellations on the day of surgery due to preoperative instructions not being followed, calls to the local health information line, calls to the provincial health information line, emergency department consultations, unplanned readmissions, or medical visits for problems related to the surgical procedure within the first 30 days after the intervention. The secondary outcome will be to evaluate cost utility using a questionnaire assessing quality-adjusted life years. A blinded independent research team will analyze outcomes. All data will be analyzed according to the intention-to-treat principle. A sample size of 500 subjects in each group was calculated to detect a 21% reduction in postoperative complications with a power of 90%. This study has been approved by the ethics board of Centre hospitalier de l'Université de Montréal (University of Montreal Health Centre). No employee of LeoMed was involved in the study conception, and none will be involved in either data collection or analysis. RESULTS: Results of this trial will be useful to determine the economic benefit of a telecare platform specifically developed for surgical outpatient pathways. CONCLUSIONS: We believe that the deployment of a dedicated perioperative telehealth app will lead to better patient care and fewer postoperative complications, which will lower all types of costs related to surgical outpatient care.
