Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Intervention group
A synthetic cast will be applied to patients who are admitted into the study and allocated to the intervention group. This will be applied on the initial ED presentation and the patient will be discharged with a referral for Fracture clinic follow-up as per normal Monash Health protocol. At this appointment the Fracture clinic doctors will review the plaster and monitor the progress of the fracture healing as per standard care. The synthetic cast will be changed if any issues arise with it, or it will remain in-situ for the duration of the immobilisation period (generally 6 weeks).

We plan to work out the average time it takes to apply the cast when we do the training of their applications (approximately 20 casts). We would estimate it would take about 10 min

Treatment: Devices
Comparator / control treatment
A Plaster of Paris cast (POP) will be applied to patients who are admitted into the study and allocated to the control group. This will be applied on the initial ED presentation and be discharged with a referral for Fracture clinic follow-up as per normal Monash Health protocol. At this appointment, the Fracture clinic doctors will review the plaster and monitor the progress of the fracture healing as per standard practice. The POP cast will be changed if any issues arise with it, or it will remain in-situ for the duration of the immobilisation period (generally 6 weeks).

We plan to work out the average time it takes to apply the POP in the ED (approx. 20 plasters) before the start the trail.. We would estimate it would take about 10 min

Outcomes
Primary outcome [1] 326800 0
The primary outcome measure in this study will be the number of cast used in the immobilization of a fracture.

This information will be obtained from the medical records from the hospital as well as data collected at the fracture clinic reviews. The plaster technicians will fill in an Interim Case Report which will gather data on why the cast was changed, where it was changed. This will be cross referenced to the medical records
Timepoint [1] 326800 0
This will be calculated from the initial Emergency Department cast until the final cast is removed at the fracture clinic (usually around 6 weeks)
Secondary outcome [1] 392708 0
1. Average costs of current pathway vs Synthetic cast applied in the Emergency Department. By calculating the number of casts used in the management of the fracture. The cost of the cast will be determined as an average prior to trial commencing i.e average cost of material and time to apply.

This will be calculated by averaging the number of casts used in each patients care through data collection from the hospital medical records
Timepoint [1] 392708 0
Average cost will be determined approximetely 6 weeks post initial ED presentation
Secondary outcome [2] 392709 0
The length of time the initial cast will remain in situ, until it is removed.

This will be calculated by auditing the hospital medical records for the individual patient
Timepoint [2] 392709 0
The length of time the initial cast which was applied in the Emergency Department remains insitu until it is removed either in the Emergency Department or fracture clinic.
Secondary outcome [3] 392710 0
Number of fracture clinic / Emergency Department visits for management of wrist fractures

This will be calculated by auditing the hospital medical records for the individual patient
Timepoint [3] 392710 0
Data will be collected after the final fracture clinic appointment (usually around 6 week)
Secondary outcome [4] 392711 0
Patient satisfaction questionnaire
This will be administered at the time of the removal of the initial plaster in either the Emergency department or fracture clinic

This questionnaire is based on the questionnaire used by Ingliss et al (2013) in their synthetic cast study. This has been modified to be able to be easier to interpret by patients who are required to complete it
Timepoint [4] 392711 0
This will be administered at the time of the removal of the initial plaster in either the Emergency department or fracture clinic

Eligibility
Key inclusion criteria
Patients to be included must meet the following criteria:

1. Paediatric including and over the age of 5 years of age and adults
2. Fracture acutely sustained (previous 72 hours), undisplaced forearm fracture (including distal radius and/or ulna [epiphysis/metaphysis]
3. Below elbow circumferential casting is the management in accordance to Monash Health Orthopaedic recommendations.
4. Ongoing conservative management is planned
5. Ongoing management expected to take place within Monash Health (Monash Emergency and Monash Orthopaedic units)
6. Able to give informed consent.
Minimum age
5 Years
Maximum age
No limit
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
Patients will be excluded if they have any of the following conditions:

1. Compound (open) fracture
2. Significant swelling and/or neurovascular compromise such that initial backslab (rather than circumferential casting) is recommended.
3. Isolated proximal forearm fractures such as radial head/neck, olecranon or coronoid process fractures of ulna(displaced or undisplaced).
4. Any forearm fracture or fracture-dislocation for which operative management is recommended (acute or delayed).
5. Inability to understand the study explanation/requirements for any reason (e.g. language difficulties, abnormal/reduced cognitive state).
6.Adequate circumferential cast already in place (from GP or non-Monash referring hospital).
7.Fracture requiring surgical stabilisation

Summary
Brief summary
This study will be a randomised controlled trial aiming to compare traditional Plaster of Paris (POP) cast versus synthetic cast for management of patients with simple wrist fractures who present to Monash Health emergency departments (ED). We hypothesize that if synthetic casts are applied in the ED in the first instance, although this material is more expensive than POP, this would eliminate the need for further cast changes at the Fracture Clinic review (usually 2/52 post injury). Therefore this intervention would reduce cost and time for the organisation overall. The primary outcome measure will be total number of cast changes until immobilisation by cast is no longer required. Secondary outcomes will include cost effectiveness and patient satisfaction. 110 participants will be recruited to the study between July 2021 to January 2022.
Evidence gained from this study will contribute to future treatment of wrist fractures in the ED. It would reduce the cost to the healthcare system and demand on Fracture Clinic and also improve patient satisfaction and comfort. This practice may be translated into other health care networks in Australia and worldwide.
