Charting Postoperative Trajectories in Patients With Cancer: Perspectives From a Resource-Constrained Setting in...

Area of Science:

• Critical Care Medicine
• Surgical Outcomes Research
• Oncology

Background:

• Perioperative monitoring in critical care is vital for patient outcomes but resource-intensive.
• Identifying high-risk surgical patients is crucial for efficient resource allocation in critical care settings.
• Understanding prognostic factors can guide strategies to reduce postoperative mortality and morbidity.

Purpose of the Study:

• To identify prognostic factors predicting postoperative mortality and morbidity in surgical patients.
• To aid in the identification of high-risk individuals requiring intensive monitoring.
• To inform the development of strategies for reducing mortality in resource-constrained environments.

Main Methods:

• A cohort study analyzing secondary data from 421 cancer patients aged 18+ admitted to critical care.
• Extraction of preoperative, intraoperative, and postoperative parameters from electronic health records.
• Descriptive analysis and log-binomial regression using STATA v.12 to determine predictors of poor outcomes (morbidity or mortality).

Main Results:

• The study included 421 patients (mean age 58.02 years), with 68% experiencing significant postoperative morbidity and 3% mortality.
• Predictors of poor outcomes included an Acute Physiology and Chronic Health Evaluation (APACHE-II) score >15 (RR 4.5), surgeon experience <10 years (RR 1.7), and blood loss >100 ml (RR 2.42).
• Tobacco use was prevalent (88%) among the study population.

Conclusions:

• Higher APACHE-II scores, significant intraoperative blood loss, and operating by less experienced surgeons are key determinants of poor postoperative outcomes.
• These factors underscore the need for vigilant postoperative monitoring in critical care facilities for high-risk surgical patients.
• Targeted interventions and resource allocation based on these prognostic factors can potentially improve patient survival and reduce complications.
