Original articleObesity surgery mortality risk score: proposal for a clinically useful score to predict mortality risk in patients undergoing gastric bypass
Section snippets
Methods
The database of 2075 patients who had undergone open or laparoscopic GBP at Virginia Commonwealth University hospitals from 1995 through 2004 was analyzed. Since the database was started in 1987, it has been prospectively maintained and updated using the patients’ in-hospital and clinic records. The institutional review board approved the collection of the data in a secure database and reporting on the analyses. Patients were considered eligible for surgery for obesity according to the 1991
Results
Table 1 shows the univariate analysis results of the preoperative variables examined. Several factors that increased the likelihood of postoperative pulmonary complications were identified as significant on univariate analysis, including obstructive sleep apnea, venous stasis disease, and OHS. Conditions known to correlate with an increased risk of PE include OHS, right heart failure, pulmonary hypertension, venous stasis disease with or without skin ulcers, and previous venous thromboembolism
Discussion
In this study, we used univariate and multivariate techniques to analyze the data from a database of a tertiary care center that has specialized in bariatric surgery for >2 decades. Statistically significant preoperatively attainable risk factors were identified using univariate analyses, and then a model was selected based upon multivariate regression analysis. The goal was to create a scoring system for risk assessment that might gain acceptance as a clinically relevant framework for

2022, Obesity Research and Clinical PracticeCitation Excerpt :Recently, Sun Y et al. [17] also reported that greater preoperative BMI was associated with a higher risk of 30-day mortality after adjusting for age, sex, and ethnicity. Although the widely used Obesity Surgery Mortality Risk Score (OS-MRS) [18] sets the cut-off point of BMI at ≥ 50 kg/m2, in our study, the mortality rates in groups I and II were no different at 0.1 %. This probably highlights that in the era of laparoscopic BS, the cut-off of 50 kg/m2 is no longer clinically relevant.
