Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
graduated three layer straight tubular bandaging system which consists of an elastic tubular bandage that is often used as a support bandage.
In this study the investigational product will be used in graduated lengths of 3 layers of the tubular bandage system as follows:
1. from base of toes to just under knee (long layer)
2. from base of toes to above calf pump (medium layer)
3. from base of toes to mid gaiter (short layer)
participants will be bandaged weekly for 12 weeks and will keep this bandage on between treatment visits.
Intervention code [1] 3403 0
Treatment: Devices
Comparator / control treatment
Standard short stretch compression bandaging system consists of:
1. A padding layer
2. 10cm inelastic short stretch compression bandage
3. A tubular stocking.
All layers of standard compression therapy will be applied from base of toes to just under the knee. Participants will be bandaged weekly for 12 weeks and will keep this bandage on between treatment visits.

Outcomes
Primary outcome [1] 4757 0

Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Patients will be randomised to receive either control or intervention group using a central computer generated random number generated by using a central computer generated randomisation sequence.
The randomization code will be sent to the Investigator (or designee) who will prepare treatments according to the randomisation code.

To decrease bias and confounders the decision to accept or reject a participant will be made using inclusion and exclusion criteria. Informed consent will be obtained by participant without knowing the next assignment in the sequence. Independent clinicians will apply compression bandage systems according to the computer generated list allocation. The code will be revealed to the researchers once the recruitment, data collection and wound measurement analysis are completed. The allocation list will be stored within the Clinical Informatics and Data Management Centre of the Department of Epidemiology and Preventative Medicine (DEPM).
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomisation will be stratefied by study site and wound size. Patients will be randomised to receive either control or intervention group using a central computer generated randomisation sequence.

Summary
Brief summary
Venous disease is the most common cause of leg ulcers. The refractory nature of venous ulcers affects the quality of life and work productivity of those persons afflicted. This, in combination with the high costs of long-term therapy, makes venous ulcers a major health problem in developed countries. Management of venous leg ulcers is based on understanding pathophysiologic abnormalities. In recent years, identifying prognostic factors for healing and developing novel therapeutic approaches for venous ulcers have offered valuable tools for the management of patients with this disorder.

Compression increases ulcer healing rates compared with no compression. Multi-layered systems are more effective than single-layered systems. High compression is more effective than low compression but there are no clear differences in the effectiveness of different types of high compression(1).
The aim of this study is to evaluate the efficacy and safety of graduated three layer straight tubular bandaging when compared to 4 layer compression bandaging in healing venous ulcers in patients with chronic venous ulceration.
