Is the SORT score reliable in predicting postoperative 30-day mortality after a nonemergency surgery in Saudi population?

Abstract

Context: The process of stratifying patient risk preoperatively helps in the decision about the best-possible postoperative care for patients. There have been many scoring systems that are used in anesthesia practice. Aims: To find out whether there is any difference between the mortality predicted from SORT scoring and the observed mortality among Saudi patients. Settings and Design: This was a prospective, observational study in which we included patients underoing nonemergency surgical procedures at the Security Forces Hospital, Riyadh. Methods and Material: We calculated the SORT scores for all the included patients. We then collected the 30-day mortality data of all the patients having nonemergency surgical procedures. Statistical Analysis Used: We calculated the expected mortality ratio. A P value of less than 0.05 was considered significant. Results: The mean SORT mortality risk score (%) for the whole sample was 0.30. The expected number of deaths was 1.638 while the observed deaths were 2, which yields an O/E ratio of 0.819 (p-value: 0.006). The O/E mortality ratios for patients in each individual ASA class were found to be statistically insignificant which means that SORT score can reliably predict mortality for each ASA class. Conclusions: SORT scores can be used to predict 30-day mortality after nonemergency surgeries in Saudi population.

Comparative evaluation of scales for predicting an unfavorable postoperative outcome: Preliminary results of the multicenter study “The role of concomitant diseases in the stratification of the risk of postoperative complications in abdominal surgery STOPRISK”

“…Международное проспективное обсервационное исследование, проведенное в 274 больницах Великобритании, Австралии и Новой Зеландии с участием взрослых, перенесших операцию, требующую пребывания в больнице не менее 1 дня, показало, что как шкала SORT, так и шкала SRS переоценивают риск летального исхода, но в целом SORT продемонстрировала лучшую дискриминацию (SORT AUROC 0,90, 95% ДИ 0,88-0,92; SRS AUROC 0,85, 95% ДИ 0,82-0,87) [37]. Внешняя валидизация шкалы SORT в Саудовской Аравии показала схожую картину: соотношение предсказанная летальность/зарегистрированная летальность составило 0,819 (p = 0,006) [38]. Возможности применения шкалы в оценке риска послеоперационных осложнений оказались еще более скромными: работа, выполненная Wong D. et al (2017) на когорте пациентов в об щей хирургии, показала AUROC 0,72 для шкалы SORT в прогнозировании 7-дневных осложнений [39].…”

Is a guideline required to predict the intensive care unit need of patients over 65 years of age during the preoperative period? A comparison of the American Society of Anesthesiologists, lung ultrasound score, Charlson age-added comorbidity index, surgical outcome risk tool indexes

“…The SORT may predict the 30-day risk of mortality in patients undergoing non-cardiac and non-neurological surgeries. [ 22 ] Although SORT was developed as a pre-operative risk assessment tool, it may also be applicable as a risk adjustment tool.…”
