Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Reflectance confocal microscopy (RCM) imaging will be performed on patients who were already planned to have a skin biopsy, prior to having the biopsy. The imaging takes from 5-30mins. The patient will have a small amount of oil applied to their skin and then have either a hand-help device pressed against their skin or have a metal ring stuck their skin with a imaging head then attached to this. The imaging and analysis will be performed by a sub-specialised dermatology consultant in a once off intervention occurring in the outpatient dermatology department of the Princess Alexandra Hospital, a tertiary public teaching hospital
Intervention code [1] 296420 0
Diagnosis / Prognosis
Comparator / control treatment
A skin biopsy (the current gold standard in skin cancer diagnosis) will be performed on every lesion imaged. The biopsy and images will be analysed independently and blinded to the result of the other/

Outcomes
Primary outcome [1] 300212 0
The comparison between the number of biopsies required to make a diagnosis with and without RCM imaging.
This outcome will be measured by comparing the difference between the real management plan and the hypothetical management plan based on RCM imaging.
Timepoint [1] 300212 0
7 days after intervention
Primary outcome [2] 300213 0
The difference in money required to perform the hypothetical management based on the RCM imaging compared to the actual management that occured.
Timepoint [2] 300213 0
7 days after the biopsy
Primary outcome [3] 300214 0
The difference in patient comfort between RCM imaging and having a biopsy through using a questionnaire specifically designed for this study.
Timepoint [3] 300214 0
Collected via a questionaire. To be finalised on day of biopsy and imaging
Secondary outcome [1] 329410 0
Comparison of the diagnostic accuracy RCM imaging compared to that of a skin biopsy. This is be measured through the comparing the diagnosis based on a blinded RCM analysis report and the diagnosis according to the current gold standard, skin biopsy.
Timepoint [1] 329410 0
7 days after biopsy when the pathology results are finalised
Secondary outcome [2] 329487 0
Determining the amount of money a patient would be willing to spend to have RCM imaging through the use of a questionnaire especially designed for this study
Timepoint [2] 329487 0
A questionnaire will be completed on the day after the RCM imaging and biopsy has been completed.

Summary
Brief summary
The aim of this study is determine what benefits and costs are associated with integrating Reflectance confocal microscopy (RCM) imaging into dermatological clinical practice.

Who is it for?
You may be eligible to join this study if you have been identified during the routine dermatological appointment to require a skin biopsy of a lesion suspicious for either melanoma or basal cell carcinoma.

Study details
The study involves a one-off patient visit that will be incorporated within their standard dermatology visit. During the study visit reflectance confocal imaging will be performed on any lesion which has been identified as requiring a biopsy. Skin biopsy will be performed for every imaged lesion. Participants will also be asked to complete a questionnaire reflecting on their experience of both RCM imaging and having a biopsy, their previous skin cancer history and treatments and their willingness to pay for the service.

Overseas centres have analysed the benefit of integrating RCM in clinical practice, however, to date there has not been a study done in Australia to assess this. As the Australian health system, and particularly the public dermatological service, differs from other countries, it will be beneficial to study the specific benefits of using RCM imaging within the clinical practice of a Queensland public hospital dermatology department.
