Brief Summary

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.

Secondhand Smoke Exposure

Study Design

• Observational Model Type: COHORT
• Study Time Perspective: PROSPECTIVE

Study Groups

Provide additional information about the group or cohort, including a description of any interventio

Eligible participants were adult parents who declared current tobacco use and were present at their child's ambulatory surgical visit. Exclusions included parents absent on the day of surgery, procedures postponed, or explicit refusal to participate.

Counselling session

Intervention Type: 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.
