Outcome Measures
Primary Outcomes (1)
30-Day Postoperative Mortality
"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
30 days post-surgery
Interventions
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
Eligibility Criteria
The study population includes adult patients aged 18 years or older who underwent elective non-cardiac surgeries at a tertiary hospital. Patients with emergency surgeries, incomplete data on surgical start times, or missing follow-up information were excluded from the analysis. The study focuses on evaluating the impact of surgical start times (morning, afternoon, and nighttime) on postoperative outcomes, including mortality, complications, and ICU admission.
You may qualify if:
- Patients aged 18 years or older
- Patients who underwent non-cardiac surgery
You may not qualify if:
- Emergency surgeries
- Cadaver surgeries
- Transplantation surgeries
- Patients with incomplete or missing data, such as follow-up information, operation start times, or laboratory values
