NCT04703569

Brief Summary

The objective of the study is to compare the effect of two treatments on the healing of venous ulcers in follow-up people in two Primary Health Services, in a city in southern Brazil. The two treatments that will be tested are: (1) the high compression elastic bandage and (2) Unna boot. The two treatments are indicated for the treatment of people with venous insufficiency and who have an active ulcer. The treatment will last 26 weeks (6 months). Once a week, during 26 weeks, a nurse will perform the dressing and will apply the therapy high compression elastic bandage or Unna boot according to a drawing and in every two weeks an evaluator will assess the characteristics of the ulcers and the size.

Outcome Measures

Primary Outcomes (1)

  • Effect of the therapies on time and on the healing characteristics of venous ulcers

    A blind evaluator for therapies will assess the characteristics of the ulcers using a Likert scale, being 1 the worst score and 5 best score, proposed to Nursing Outcomes Classification (NOC), in the outcome Wound Healing: Secondary Intention. This outcome has indicators to assess the healing characteristics, such as granulation tissue; necrosis; epithelial tissue; exsudate; erythema; oedema; macerated skin; odor and planimetry.

    On first day and in every two weeks, during 26 weeks.

Secondary Outcomes (4)

  • The effects of the therapies at the level of pain

    On first day and in every two weeks, during 26 weeks.

  • Cost-effectiveness of the therapies

    26 weeks

  • Health-related quality of life

    On first day, on the 12ª week and on the 26ª week.

  • The effects of the therapies at the tissue integrity

    On first day and in every two weeks, during 26 weeks.

Study Arms (2)

Monolayer high compression elastic bandage

EXPERIMENTAL

An elastic bandage of cotton, viscose, nylon and elastane

Procedure: Dressing with monolayer high compression elastic bandage

Unna boot

ACTIVE COMPARATOR

A wet bandage with zinc oxide

Procedure: Dressing with Unna boot

Interventions

The nurse will be apply the therapy high compression elastic bandage once a week, during 26 weeks

Monolayer high compression elastic bandage

The nurse will be apply the therapy Unna Boot once a week, during 26 weeks.
