Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The use of Point-Of-Care Ultrasound (POCUS) bladder scan, and whether it reduces the time taken to collect a clean catch urine from a non-toilet trained child.

As per the control arm, parents/carers were provided with the same written information on how to collect a CCU sample. The child was prepared for collection in the same fashion as the control arm (nappy/underwear removed, and genitals gently cleaned with cotton wool and water). A urine sample pot was provided at the same time as the bladder scan, and parents/carers advised to be ready for collection of urine. Starting time was recorded at the beginning of the ultrasound.
The Sonosite X-Porte ultrasound machine was used (with room temperature gel pre-applied) to calculate bladder volume via the in-built ‘Bladder Volume’ function. If the bladder volume was over 7ml/kg, then the parents/carers were informed that micturition is imminent and advised to be on high alert for collection. If no urine was passed in 30 minutes, then the bladder scan was repeated. If there was minimal increase in volume, then parents/carers were encouraged to increase oral fluid administration. Conversely, if the repeat scan showed a volume of over 7ml/kg, the parents/carers were advised to be vigilant due to impending micturition. All ultrasounds were either performed or directly supervised by one of the authors (RL) who is accredited for the Extended Focused Abdominal Scan in Trauma (EFAST) with the Australasian College for Emergency Medicine (ACEM).

Comparator / control treatment
Traditional 'watch and wait' method of collecting a clean catch urine sample from a non-toilet trained child.

The patients’ parents/carers were provided with written information on how to collect a CCU sample. The patient was prepared for a CCU sample by removing nappy/underwear, and cleaning of genitals with cotton wool and water. A sterile urine sample pot was provided, and time recorded as soon as the nappy was undone and the urine pot provided. Time of sample collection and number of attempts required were also recorded.

Outcomes
Primary outcome [1] 329185 0
Time taken to collect a clean catch urine sample.

This was recorded as two time stamps, firstly when parents/caregivers were provided with the urine pot/bladder scan, and second time stamp when parents/caregivers alerted medical staff to successful clean catch urine.
Timepoint [1] 329185 0
From time of setting parents/caregivers up with sterile pot for clean catch urine, till collection of clean catch urine by parents/caregivers
Secondary outcome [1] 401728 0
Frequency of missed collections, assessed by parents/caregivers self reporting of missed collection.

This will be assessed by direct parent/caregiver interview, as well as medical record review
Timepoint [1] 401728 0
Parents/caregivers will be required to report every missed collection, from provision of sterile pot, to collection of clean catch urine, or till discharge
