Smoking and postoperative outcomes in elective cranial surgery

Area of Science:

• Neurosurgery
• Public Health
• Surgical Outcomes Research

Background:

• Smoking is a known risk factor for numerous adverse health outcomes.
• The impact of smoking on short-term outcomes following elective cranial surgery remains unclear.
• Understanding these risks is crucial for perioperative management and patient counseling.

Purpose of the Study:

• To evaluate the association between current/prior smoking and postoperative complications within 30 days.
• To determine if the number of smoking pack years influences adverse outcomes in elective cranial surgery patients.
• To inform clinical decisions regarding smoking cessation before elective cranial procedures.

Main Methods:

• Analysis of data from the 2006-2011 American College of Surgeons' National Surgical Quality Improvement Project.
• Inclusion of 8296 patients undergoing elective cranial surgery, categorized by smoking status (current, prior, never).
• Propensity score matching and logistic regression used to compare outcomes and assess pack year impact.

Main Results:

• No significant difference in 30-day postoperative adverse outcomes was observed between current smokers, prior smokers, and never smokers in both unadjusted and matched analyses.
• The number of pack years did not predict worse outcomes in smokers compared to never smokers.
• Logistic regression revealed no association between smoking status and adverse postoperative events.

Conclusions:

• Smoking history (current or prior) and pack years are not associated with increased 30-day morbidity or mortality after elective cranial surgery.
• While smoking cessation benefits overall health, it may not be essential for improving short-term outcomes of this specific surgical group.
• Postponing elective cranial surgery solely for smoking cessation may not be clinically necessary based on these findings.
