Perioperative Counselling and Parental Awareness of Second-hand Smoke

In a single-centre observational before-after study (n=31 parental smokers), a standardized ~15-minute tobacco-counselling intervention delivered during the paediatric ambulatory pathway significantly increased parental awareness of secondhand-smoke harms (median total score 34→46; p=0.0026). Item-level gains were greatest for perceived anaesthetic risk and misconceptions about tertiary/indirect exposure. Session acceptability was high, but self-reported behavioural change at 30 days was limited. The perioperative consultation is a feasible "teachable moment"; integration with visual aids, objective exposure measures, structured cessation referral and longitudinal follow-up should be considered to translate awareness into sustained exposure reduction.

Treatment and study plan

Counselling session

Behavioral

Each enrolled parent received a single, standardized counselling session (~15 minutes) delivered in the ambulatory unit by a certified tobacco counsellor. The session followed a fixed script and covered: (1) types of tobacco smoke exposure (primary, secondary and tertiary), (2) health consequences for children with emphasis on perioperative respiratory and anaesthetic risks, (3) practical measures to reduce household exposure (smoke-free home/car rules, behavioural strategies), and (4) brief advice on initial cessation steps and referral options. Structured handouts and signposting to support services were offered when appropriate.

Primary outcomes

  1. 60-points score parental awareness

    Time frame: 4 hours

    The primary outcome was change in parental awareness measured by a six-item questionnaire (each item scored 0-10; total range 0-60) administered at baseline (arrival), immediately after counselling, and at 30 days by telephone.

Secondary outcomes

  1. Smoking changes

    Time frame: 30 days

    Self-reported changes in smoking behaviour at 30 days
