Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Eligible and consenting participants will be asked to record their pain scores using three different scales, the Numerical Rating Scale (NRS), Visual Analog Scale (VAS) and on the Pain Tracker App, on the Pain Level Recording Form. The NRS and VAS are current standard of care. The Pain Tracker App will be on the researcher or surgeons phone, this device will be handed to the participant who will rate their pain using the App. Once completed, the researcher will transfer the recorded pain score provided by the App onto the Pain Level Recording Form and then exit the App without saving any details. The Pain Tracker App will record and hold no patient details. The participant will also be asked which scale they preferred to use and this will also be recorded on the Pain Level Recording Form.

Treatment: Devices
Comparator / control treatment
As this project aims to validate the Pain Tracker App there will be no control group i.e. this is an uncontrolled study.

Uncontrolled

Outcomes
Primary outcome [1] 331250 0
This primary outcome of this study will be to compare the new Pain Tracker App against the 11-point VAS measurement for pain, currently the standard of pain measurement care at Epworth healthcare.
Timepoint [1] 331250 0
The pain measurements will be collected at least twice daily (patient is free to enter as many times per day as they wish) immediately following surgery. This will occur until the follow up appointment, which is generally 2-6 weeks following surgery.
Secondary outcome [1] 409305 0
Assess patient preference when using the three pain recording scales. Participants will be asked which method they preferred to use when measuring pain.
Timepoint [1] 409305 0
This will be collected on ward review post orthopaedic surgery.
Secondary outcome [2] 410930 0
Compare the OME dosage for participants in the 12 hours prior to reporting in Pain App against the report pain level collected on the Pain Level Recording Form.
Timepoint [2] 410930 0
This will be collected on ward review post orthopaedic surgery.

Efficacy
Statistical methods / analysis
Statistical power analysis was undertaken using the method of Zou (2012), implemented in R 4.1 (R Foundation for Statistical Computing, Vienna, 2021). Agreement between instruments such as the app and the standard measure of pain (VAS) is generally measured by the intraclass correlation coefficient (ICC). For an expected minimum ICC of 0.80, the lower limit of a 95% one-sided confidence interval to be no lower than 0.70, and with 80% statistical power, a sample size of 117 patients would be required. Allowing for 10% attrition, (117/0.90) = 130 patients would be required. Statistical analyses will include graphic and descriptive summaries, Bland-Altman plots and ICCs, employed in our previous studies.
