About this trial
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.

Nurse-led AWARD brief smoking cessation counselling with active referral and tailored perioperative booklet in the pre-anaesthetic assessment clinic
Procedure/SurgeryThis intervention is a structured, nurse-led, behavioral smoking cessation program embedded within a nurse-run Pre-Anaesthetic Assessment Clinic for elective surgical patients who smoke. It consists of a single brief counselling session (approximately 3-5 minutes) delivered by trained perioperative nurses using the standardized AWARD model (Ask, Warn, Advise, Refer, Do-it-again), with content specifically tailored to perioperative risks and benefits of quitting before surgery. During the session, nurses use exhaled carbon monoxide testing as a motivational tool, provide a perioperative-focused, tailor-made smoking cessation booklet validated by a consultant anaesthetist, and make an active referral to the hospital's smoking cessation service rather than passive signposting. Fidelity is supported through dedicated nurse training, competency assessment, and ongoing supervision, and the intervention is reinforced on the day of surgery and at 1-month follow-up.
Usual pre-anaesthetic care without structured smoking cessation
Procedure/SurgeryParticipants receive usual pre-anaesthetic care from surgeons and anaesthetists. Smoking advice, if given, is brief and unstructured, with no standardized counselling protocol, no tailored perioperative booklet, and no protocolised active referral beyond the routine hospital leaflet.

Trial outcomes
Primary outcomes
1
Complete smoking abstinence
A short-term Smoking Abstinence: The proportion of patients who report complete smoking abstinence (7-day point prevalence abstinence) biochemically validated by exhaled CO levels \< 6 ppm on the day of surgery and negative result of Cotinine rapid salvia test and at 4 weeks post-counseling (1-Month Sustained Cessation Rate by self- report phone survey).
Time frame
on the day of surgery and at 4 weeks post-surgerySecondary outcomes
1
The average number of cigarettes smoked per day at surgery day and 4 weeks post -surgery
The average number of cigarettes smoked per day at surgery day and 4 weeks post -surgery among those who have not achieved complete abstinence. Self-reported daily cigarette consumption (percentage reduction compared to baseline).
Time frame
on the surgery day and 4 weeks post -surgeryOther outcomes
1
The rate of major postoperative complications
The rate of major postoperative complications (e.g., pneumonia, wound infection, cardiovascular events) within 30 days post-surgery, as data will be extracted from electronic medical records (Clinical Data Analysis and Reporting System (CDARS)).
Time frame
within 30 days post-surgery,2
Patient Satisfaction
Patient Satisfaction Mean score on a 5-point Likert scale assessing satisfaction with smoking cessation support received, administered via questionnaire at 1 month's post-surgery. Mean score on a 5-point Likert scale for patient satisfaction with smoking cessation support (range 1-5, where higher scores indicate better satisfaction). Assesses satisfaction with the counselling service, leaflet content, and overall care.
