Treatment and study plan

Surgical Start Time

Procedure

This intervention focuses on the retrospective analysis of the association between surgical start times (morning, afternoon, and nighttime) and postoperative outcomes in non-cardiac surgeries. The study evaluates how the timing of surgery impacts mortality, complications, transfusion rates, and ICU admissions in a tertiary hospital setting

Primary outcomes

  1. 30-Day Postoperative Mortality

    Time frame: 30 days post-surgery

    "The primary outcome measure is the incidence of 30-day postoperative mortality in patients undergoing non-cardiac surgeries. Mortality is defined as death occurring within 30 days following the surgery. The study aims to evaluate the association between surgical start times (morning, afternoon, and nighttime) and the risk of mortality
