Description of intervention(s) / exposure
Structured interview via phone call to assess post surgical pain at 3 weeks and 12 weeks post tonsillectomy with or without adenoidectomy for any indication.
Each interview will take between 5-10 minutes and will be conducted by a member of the study team. The script and interview questions are set but a formal questionnaire will not be used.
If pain is found on the second phone call at 12 weeks, the participant will be assessed by pain physician which may be in person or via telehealth within 5 days.
If there is suspicions of chronic post surgical pain the Electronic Persistent Pain Outcome Collaboration (ePPOC) patient/parent questionnaire inclusive of the PedsQL questionnaire may be completed to guide further management.
A further detailed pain history will be undertaken by a pain physician to determine if the persistent pain is secondary to surgery and directed for further management.

Outcomes
Primary outcome [1] 333495 0
Prevalence of chronic post surgical pain following paediatric tonsillectomy.

If there are suspicions of CPSP, the child and family will be referred to the RCH Chronic Pain Clinic where they will be seen by a Pain physician either in person or by telehealth along with an electronic paediatric pain outcome collaboration (ePPOC) questionnaire inclusive of the PedsQL questionnaire and a further detailed pain history will be undertaken to determine if the persistent pain is secondary to surgery and directed for further management.
These questionnaires will only be administered to those groups who report ongoing pain at the second phone call (12 weeks post tonsillectomy) following a referral to the RCH chronic pain clinic and review by a specialist paediatric pain physician.

Statistical methods / analysis
A convenience sample of 150 (anticipating a dropout rate of around 10-15%) has been chosen.

If we determined 5% prevalence then the 95% confidence interval would be 1.5-11% which provides an acceptable degree of precision. If we found a 0% prevalence the upper bound of the 95% confidence interval would be 3.6%. If we determined a 10% prevalence then the 95% confidence interval would be 5-17% and we will then conduct a series of exploratory univariate analyses to assess if the pain is associated with any particular patient or surgical factor.

Following determination of prevalence for chronic post surgical pain, we will assess descriptive statistics of the population (age, gender, weight, BMI, surgical indication, surgical type) and then impact of chronic post surgical pain if present (ePPOC Questionnaire). All data will be expressed as a number, range, percent and mean and standard deviation as appropriate.

The nature of the pain will be described descriptively.

For the exploratory analysis where pain is present or not, numerical data between groups will be compared with a Student's t-test. Associations between categorical variables will be analysed using Pearson's chi squared tests. Logistical regressions will be performed to identify relationships between variables and chronic post surgical pain. A value p < 0.05 will be considered statically significant.
