Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Outcomes
Primary outcome [1] 328738 0
“Average pain on that postoperative day” as reported on a Wong-Baker FACES pain rating scale where 0 is “no pain at all” and 10 is “the worst pain I’ve ever felt”. This will be self-reported by all the participants aged greater than 5 years and with parent guidance in children aged 3 or 4 years.
Mode of self-reporting will be via study-specific online questionnaire.

Secondary outcome [2] 400205 0

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Randomised allocations will be delivered to administration staff in sealed white envelopes with no distinguishing features containing a randomisation number. Researchers who will be undertaking data collection and the operating doctors will have no knowledge of the allocation groups. The surgical team will prescribe either the intervention or the control measures according to randomisation. Patients and their guardians will know their allocation.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Participants will be randomly assigned to either control or experimental group with a 1:1 allocation as per a computer generated randomisation sequence stratified by age and gender (block randomisation). Block sizes will not be disclosed, to ensure concealment.
Masking / blinding
Blinded (masking used)
Who is / are masked / blinded?
The people receiving the treatment/s
The people administering the treatment/s
The people assessing the outcomes
The people analysing the results/data

Efficacy
Statistical methods / analysis
Demographic and clinical characteristics of randomised patients will be summarised by group. Numeric variables will be reported as mean with standard deviation or median with interquartile range (IQR) if skewed. Categorical variables will be reported as frequency count and percentage. Pain scores will be summarised by group at days 1, 3, 5, 7, 10, and 14.

The primary outcome will be reported as the mean difference with 95% confidence interval in post-operative pain score at Day 7 (intervention versus control) and will be analysed using a t-test and a linear regression adjusted for gender and age group. All patients with non-missing outcome data will be included in the analysis and patients will be analysed according to their randomised group allocation as per the intention-to-treat (ITT) principle.

Secondary outcomes will be compared between groups using chi-squared tests/logistic regression for binary outcomes (such as Day 14 postoperative bleeding) or log-rank tests/Cox regression for time-to-event outcomes (such as first pain-free day).

A sensitivity analysis for compliance will be conducted for the primary outcome. Safety data will be reported per group as total number of adverse events, number of participants with adverse event(s), and number of events by severity category. All analyses will be conducted at a significance level of 0.05. Analysis will be performed in SAS (Cary, NC) or SPSS (Chicago, IL) or JAMOVI. Statistical analysis will be performed using the Stata program. Excel will be used for graph construction. Data analysis will be reviewed by statisticians affiliated with UON.

Summary
Brief summary
Pain after tonsillectomy is widely recognised to be not fully controlled by current pain management methods, especially in children. The aim of the study is to find out whether the use of the medication celecoxib will be useful in reducing this pain. The hypothesis is that celecoxib will be safe and effective to manage pain in children after tonsillectomy.

Data sharing statement
Will individual participant data (IPD) for this trial be available (including data dictionaries)?
No
No/undecided IPD sharing reason/comment
All analysis will be done as a group, so any incidental findings will be relevant as a cohort and not as individuals. Thus, each participant will be de-identified, with no direct results of any one patient be singled out. Their demographic details and outcomes of interest will undergo extensive analysis before publication and be regarded as a group, not individually.
