Development of the "OS-SEV90 Score" to Predict Severe Postoperative Complications at 90 Days Following Bariatric Surgery

BACKGROUND

Bariatric surgery may be associated with severe postoperative complications (SPC). Factors associated with the risk of SPC have not been fully investigated.

OBJECTIVES

This study aimed to identify preoperative risk factors of SPC within 90 days and to develop a risk prediction model based on these factors.

METHODS

We conducted a retrospective single-center cohort study based on a prospectively maintained database of obese patients undergoing laparoscopic bariatric surgery from October 2005 to May 2019. All SPC occurring up to the 90th postoperative day were recorded according to the Dindo-Clavien classification. Associations between potential risk factors and SPC were analyzed using a logistic regression model, and the risk prediction ("OS-SEV90 score") was computed. Based on the OS-SEV90 score, the patients were grouped into 3 categories of risk: low, intermediate, and high.

RESULTS

Among 1963 consecutive patients, no patient died and 82 (4.2%) experienced SPC within 90 days. History of gastric or esophageal surgery (adjusted odds ratio (aOR) 3.040, 95% confidence interval; CI 1.78-5.20, p< 0.0001), past of thromboembolic event aOR 2.26, 95%; CI 1.12-4.55, p = 0.0225), and surgery performed by a junior surgeon (aOR 1.99, 95%; CI 1.26-3.13, p = 0.003) were all independently associated with risk for SPC, adjusting for ASA physical status system (ASA) score ≥ 3, severe OSA, psychiatric disease, asthma, a history of abdominal surgery, alcohol, cardiac disease, and dyslipidemia. "the OS-SEV90 score" based on these factors was constructed to classify patients into 3 risk groups: low (≤2), intermediate (3-4), and high (≥5). According to "the OS-SEV90 score," SPC increased significantly from 2.9% in the low-risk group, 7.7% in the intermediate-risk group, and 23.3% in the high-risk group.

CONCLUSIONS

A predictive model of SPC within 90 days "the OS-SEV90 score" has been developed using 9 baseline risk factors. The use of the OS-SEV90 score may help the multidisciplinary team to identify the specific risk of each patient and inform them about and optimize the comorbidities before the surgery. Further studies are warranted to validate this score in a new independent cohort before using it in clinical practice.

Medical Education During the Coronavirus Disease-2019 Pandemic: Learning From a Distance

As paradigms of clinical care delivery have been significantly impacted by the novel coronavirus disease-2019 pandemic, so has the structure, delivery, and future of medical education. Both undergraduate and graduate medical education have seen disruptions ranging from fully virtual delivery of educational content and limited clinical care for medical students to increased clinical demands with redeployment for residents and fellows. Adherence to social distancing has led to the adoption and implementation of already available technologies in medical education, including video conferencing softwares and social media platforms. Efficient and effective use of these technologies requires an understanding not only of these platforms and their features but also of their inherent limitations. During a time of uncertainty and increased clinical demands, the approach to medical education must be thoughtful with attention to wellness of both the educator and learner. In this review, we discuss the influence of the pandemic on the existing medical education landscape, outline existing and proposed adaptations to social distancing, and describe challenges that lie ahead.
