Study type
Interventional
Description of intervention(s) / exposure
Participants undergoing a 2-4 mm skin punch or shave biopsy at Drummoyne Dermatology (a dermatology outpatient clinic) will be randomised into two groups:

Intervention group: Biopsy performed using 2-4 mm punch or shave biopsy tool, 5% chlorhexidine solution, hyfrecator and suture material (if required) without the use of a dressing pack.

Control group: Biopsy performed as per routine clinical practice using 2mm punch or shave biopsy tool, 5% chlorhexidine solution, hyfrecator and suture material (if required) with a dressing pack. Dressing pack contains: Sterile field PE material 50 x 49cm, dressing tray, 4 plain gauze swabs 7.5x7.5cm, blue sterile field 60x60cm, 3 aqua forceps 107mm, paper dressing towel 2 ply.

The intervention being tested is the omission of a dressing pack and use of reduced materials during minor skin biopsy procedures. The biopsy will be performed by doctors working at the clinic. The strategy used to monitor adherence to the intervention is direct observation by research investigator.

Study design
Purpose of the study
Diagnosis
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Group assignments will be concealed in sequentially numbered, opaque, sealed envelopes, which will be stored securely. Envelopes will be opened in numerical order only after the participant has been enrolled, ensuring allocation concealment.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomisation will occur via a computer-generated permuted block randomisation sequence to ensure balance between groups. The allocation sequence will be prepared by an independent researcher not involved in participant enrolment or assessment.
Masking / blinding
Open (masking not used)
