RESUMO
INTRODUCTION: With the evolution of educational tools, the French Military medical service has created a podcast program, Traum'Cast, about the principles of war medicine, accessible online for free. METHOD: Our objective was to measure the learning effect of the Traum'Cast program's first episode. A non-randomized pilot trial between July and December 2021 included 80 health care providers: 40 in the video podcast group compared to 40 in a group reading a pdf file providing the same information. Using a 10 MCQs, we evaluated knowledge acquisition before, just after, and 2 weeks after the intervention. It was measured using metacognition tools based on confidence marking (number of correct answers, score weighted by certainty level, and realism). RESULTS: Knowledge acquisition was better in the podcast group than in the pdf file group immediately after the intervention (correct answers: 9.0 [9.0-10.0] vs 9.0 [7.8-9.0], P = 0.015; weighted score: 177.0 [159.0-198.0] vs 160.0 [129.5-176.5], P = 0.020). This difference was persistent 2 weeks after (weighted score: 127.5 [101.8-145.2] vs 105.5 [74.2-128.5], P = 0.023). CONCLUSION: This podcast is an innovative teaching tool which has proven to strengthen the knowledge of the principles of war medicine.
RESUMO
OBJECTIVE: Life expectancy for lung-transplant patients, especially those with cystic fibrosis (CF), is leading increasingly to more retransplantations. DESIGN: Retrospective monocentric cohort study. SETTING: Foch University Hospital, Suresnes, France. PARTICIPANTS: CF patients having had a primary double-lung transplantation (pLgTx) or a retransplantation (reLgTx) from 2012 to 2021. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: The authors compared the main intraoperative and early postoperative features between pLgTx (n = 258) and reLgTx (n = 24). Demographic characteristics were similar. No patients with retransplantations had a preoperative bridge with extracorporeal membrane oxygenation (ECMO); however, 23 patients had it in the pLgTx group (p = 0.24). Patients with retransplants had longer second graft ischemic time (p = 0.02), larger intraoperative bleeding volume (p = 0.001) and blood transfusion (p = 0.009 for packed red blood cells), increased blood lactate concentrations (p = 0.002), and higher norepinephrine dose at end-surgery (p = 0.001). Extracorporeal membrane oxygenation was used during surgery in 94 patients in the pLgTx group and 12 patients in the reLgTx group (p = 0.39). Extracorporeal membrane oxygenation could not be weaned after surgery in 55 patients in the pLgTx group and 4 in the reLgTx group (p = 0.54). Despite worse preoperative renal function in the reLgTx group (p < 0.001), there was no difference concerning renal replacement therapy in the intensive care unit between groups (p = 0.08). There were no differences between groups concerning the main complications, including primary graft dysfunction. Although the difference was not statistically different (p = 0.17), mortality was 3 times higher in the reLgTx group. CONCLUSIONS: Intraoperative period of retransplantation was more convoluted but had a similar ECMO profile to primary transplantation. In addition, the early postoperative period was similar.
