The impact of residency training level on early postoperative desaturation: A retrospective multicenter cohort study.

OBJECTIVE: We studied the primary hypothesis that the training level of anesthesiology residents (first clinical anesthesia year, CA1 vs CA2/3 residents) is associated with early postoperative desaturation (oxygen saturation < 90%). We also analyzed the change in the rate (trajectory) of desaturation during the resident's development from CA1 to CA2/3 resident, and its effects on postoperative respiratory complications. DESIGN: Retrospective hospital registry study. SETTING: Two university-affiliated hospitals networks (MA and NY, USA). PATIENTS: 140,818 adults undergoing non-cardiac surgery under general anesthesia and extubation in the operating room by residents (n = 378) between 2005 and 2021. MEASUREMENTS: Multivariate logistic and quantile regression were used in the analyses. The secondary outcome was major respiratory complication within 7 days after surgery. MAIN RESULTS: In 6.5% and 1.6% of cases, early postoperative desaturation to < 90% and 80% occurred. Compared to CA2/3 residents, CA1 residents had higher odds of experiencing early postoperative desaturation to < 90% and 80% (adjusted odds ratio [ORadj], 1.07; 95%CI 1.03-1.12; p = 0.002, and ORadj 1.10; 95%CI 1.01-1.20; p = 0.037, respectively). The change in postoperative desaturation rate during the transition from CA1 to CA2/3 status varied substantially from ORadj 0.80 (decreased risk) to 1.33 (increased risk). Major respiratory complication did not differ between experience levels (p = 0.52). However, a strong decline in improvement regarding the rate of postoperative desaturation during the transition from CA1 to CA2/3, was paralleled by an increased odds of major respiratory complication for CA2/3 residents (ORadj 1.20; 95%CI 1.02-1.42; p = 0.026, p-for-interaction = 0.056). CONCLUSION: Patients treated by CA1 residents have an increased risk of postoperative desaturation. Some residents show an improvement and others a decline in postoperative desaturation rate. Our secondary analysis suggests that there should be more focus on those residents who had a declining performance in postoperative desaturation despite becoming more experienced.

Shaping Perceptions of Basic Science Education by Utilizing Real Patient Encounters.

BACKGROUND: Integrating basic science into clinical teaching has been a struggle for medical schools. However, early exposure to clinical experience has been associated with an increased understanding of the importance of basic science, positive attitudes, and developing clinical skills faster. Furthermore, early clinical exposure can help students reconnect with what drove them into medicine in the first place, especially when they are starting to feel burned out by the volume of lecture material. As a result, increasing patient experience during the first year has become a goal of many medical schools. METHODS: At Rutgers Robert Wood Johnson Medical School, interprofessional case discussions (ICDs) begin with a lecture that explicitly integrates basic science with a disease, followed by a discussion with a patient, their family, the healthcare team, and first-year students. Our objective is to explore whether ICDs enhanced the learning experience of basic science. CONTEXT: ICD satisfaction was assessed using evaluations from two different courses (2013-2016). Responses were analyzed quantitatively using descriptive statistics and qualitatively using a grounded-theory-content analysis. Study 2: A follow-up measure with current third- and fourth-year students on long-term retention of basic science was analyzed using a Wilcoxon signed rank test. Relative rankings of three different case-based teaching modalities were assessed using chi-square. RESULTS: Students reported significantly higher satisfaction with ICDs (93%) for reinforcing concepts and integrating materials compared to Flipped Classrooms (66%) and Jigsaws (65%), x 2 = 120.9, p < .001. Student comments fit into five categories: enjoyment, learning/retention, the clinical usefulness of basic science, affirming passion to be in medicine, and others. The follow-up measure indicated significantly greater retention of the biochemical basis of diseases covered during ICDs. CONCLUSIONS: While other teaching modalities integrate basic science into a clinical context, ICDs go further by displaying interprofessional care and the manifestation of the disease on the patient and the lives of their family. As a result, ICDs lead to a positive learning environment in which students feel comfortable, have a sense of rapport with the patients and health care providers, and feel motivated to learn basic science.
