Description of intervention(s) / exposure
The PATRIC Clinical Registry will collect baseline data for children presenting to Perth Children's Hospital with an Acute Respiratory Infection. Emergency Department staff (clinical and/or research staff) will identify and approach prospective participants. ED staff will provide study information (paper or digital) to gain informed consent. Study consent can be obtained by hard paper copy or digitally via a REDCap consent form on a study provided iPad. Once consent is obtained, parents will then be asked to complete a baseline survey on the iPads or via a link sent to their smartphone. Parents will then be contacted via their smartphones for up to four short follow-up surveys (weekly follow up - for a maximum of 4 weeks in total). Each survey will take 5-10 minutes to complete, which will ask questions about parental anxiety, the child's symptoms, the child's level of activity, seeking further healthcare and further treatment. In addition, parents will be asked to provide consent for access to their children's medical records and vaccination history.

Parents are given the option to withdraw from the Clinical Registry at any time. At the beginning of each follow-up survey parents will be asked if they are happy to continue to participate in the registry and if they answer with 'no' they are not sent any further surveys.

Participation in the registry also stops once parents indicate in the follow-up survey that their child is no longer sick. If this occurs, parents won't be sent any further follow-up surveys and are thanked for their time participating in the registry.

Statistical methods / analysis
Sample size calculation:
The Registry will continue to recruit patients to follow outcomes over time. As such, there is no specific sample size calculation.
Prior to reporting of specific endpoints, statistical power will be assessed to ensure sufficient data to provide robust estimates for the outcome in question.
As of 2024, >2500 children have been enrolled with outcome data available on >1500 children.

Analysis:
Proportion reaching the primary outcome and the median time to reach this outcome, as determined by parental surveys, will be assessed in the PATRIC Clinical Registry. Subgroup analysis, by age group, risk factors and treatments prescribed will be performed. Severe outcomes, including hospital representation, will be cross-checked against the medical record. The proportion lost to follow up prior to return to their premorbid state will also be reported.
Continuous variables will be summarised as mean and standard deviation for symmetric distributions and median and interquartile range (IQR) for asymmetric distributions. Categorical variables will be summarised at each level as frequency and percentage. Frequencies below five will be reported as “<5” to ensure individual confidentiality. Categorical data and time-to-event continuous endpoints will be assessed using standard statistical analytical approaches including Chi-squared; Fisher’s exact tests; Student t-test and Mann-Whitney U test. Predictors of outcomes will be assessed using logistic and linear regression models and Cox regression to account for time dependent outcomes.
These data will inform trial simulations, critical to establishing the PATRIC Platform Trial.
