Effectiveness of Brief Smoking Cessation Counselling in Pre-Anaesthesia Assessment Clinic

Starting soon · Not applicable

Conditions studied: Smoking ( Cigarette)

In brief

The goal of this clinical trial is to evaluate whether a brief, nurse-delivered smoking cessation intervention can increase pre-operative smoking abstinence and improve perioperative outcomes among adult elective surgical patients who are current smokers. The main questions it aims to answer are: Does a perioperative nurse-delivered AWARD brief counselling intervention with active referral and a tailored perioperative smoking cessation booklet increase the 7-day point prevalence abstinence rate on the day of surgery, biochemically validated by exhaled carbon monoxide and salivary cotinine? Is this intervention feasible and acceptable in the pre-anaesthetic assessment clinic in terms of recruitment, retention, intervention fidelity, and patient compliance? Researchers will compare patients receiving the nurse-led AWARD brief counselling plus active referral and tailored perioperative booklet to patients receiving usual pre-anaesthetic care without structured smoking cessation counselling, to see if the intervention leads to higher pre-operative abstinence and signals of reduced post-operative complications. Participants will: Attend the pre-anaesthetic assessment clinic where eligibility and baseline data (e.g., smoking behavior, readiness to quit, sociodemographic information) are collected and exhaled carbon monoxide is measured. Be randomly assigned to either receive brief AWARD-model counselling with active referral and a tailored perioperative smoking cessation booklet from a trained perioperative nurse, or to continue with usual pre-anaesthetic care. Have their smoking status reassessed on the day of surgery (including repeat CO and salivary cotinine testing) and at 1-month follow-up, along with collection of post-operative complication data and patient satisfaction with the smoking cessation support.
