Aim of study - To assess the incidence and pattern of behavioural changes in children undergoing ambulatory surgery and to identify the risk factors associated with post-operative behavioural changes.

Primary objective - To quantify the incidence of behavioural changes on post-operative day 1, 7 and 14 using post hospitalisation behavioural questionnaire (PBHQ-AS).

Secondary objective - To identify risk factors associated with post operative behavioural changes.

Materials and methods - A prospective cohort observational study will be conducted in Paediatric OT, Advanced Paediatric Centre, PGIMER, Chandigarh. Demographic characteristics, child’s and parents education, socio-economic status of family, child’s temperament (EASI scale), pre-operative anxiety (mYPAS scale), induction compliance checklist (ICC) prior to anaesthesia, emergence delirium (PAED scale) will be recorded which have been considered risk factors in previous studies. Following surgery the parents will be interviews via phone call on post-operative day 1, 7 and 14 to assess the child’s post-operative pain measure (PPPM scale) and post-operative behaviour (PHBQ-AS).

Analysis - Based on the above mentioned characteristics the study will aim to assess the incidence and risk factors related to behaviour changes on Indian children and the impact it has on the future outcome related to hospitalisation and surgery. This will be helpful in guiding us towards improvements in our approach toward paediatric population who are taken up for surgical procedures in the future.
