An observational study in Secondhand Smoke Exposure, sponsored by University of Liege. Completed at 1 site in Belgium. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2025-08-28.
Sponsored by University of Liege · Observational
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.
University of Liege is the lead sponsor of 242 studies on the registry; 46 are open to participants now.

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.

Behavioral: Counselling session
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.
60-points score parental awareness
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.
Time frame: 4 hours
Smoking changes
Self-reported changes in smoking behaviour at 30 days
Time frame: 30 days
