Study Details

Study Description

Brief Summary

A clinical trial will be carried out comparing the efficacy of PICO system based on negative pressure therapy (NPT) in adults with chronic ulcers compared to conventional treatments.

Condition or Disease	Intervention/Treatment	Phase
Chronic Ulcer Venous Ulcer Diabetic Foot Ulcer Pressure Injury	Device: Single-use negative pressure therapy (PICO)	N/A

Detailed Description

Due to the current scientific and clinical evidence shows that NPT offers guarantees as complementary care, improving healing and reducing amputations in patients with chronic ulcers, treatment with PICO single-use NPT, should be considered as the first option.

This clinical trial include adults from the Hospital General Universitario of Toledo with 2 arms (intervention and control) and the intervention will last 12 weeks.

The intervention proposed in the study will consist of evaluating the decrease in size, the healing rate, the adverse effects and the quality of life related to the health of the patients compared with traditional treatments.

Arms and Interventions

Arm	Intervention/Treatment
Experimental: Intervention The intervention group measurements will be carried out every 7 days, since the PICO system lasts from 7 to 14 days, except when the ulcer presents infection, which will be cured every 2-3 days.	Device: Single-use negative pressure therapy (PICO) PICO system will be applied to patients in the intervention group with diabetic foot ulcers, venous leg ulcers or pressure ulcers. This device will be changed every 7 days, until the wound is closed, or until a set period of study duration, approximately 12 weeks.
No Intervention: Control The control group measurements will be carried out every 7 days, except when the ulcer is infected, when the cure will be carried out every 2-3 days. This group (GC) will be treated mainly with betadine and sugar, or other treatments such as alginate patches, corticosteroids, Aquacel, Celestoderm or Mepitel.

Outcome Measures

Primary Outcome Measures

Change in the size of wounds [12 weeks]
The size of the wound will be measured by a nurse using a ruler every day that the patient goes to the cure to compare de first measure from the last one.
Healing time [12 weeks]
The healing time will be measured by a nurse during the days of the treatment
Cure rate [12 weeks]
The cure rate will be measured by a nurse during the days of the treatment
Number of participants with adverse effects [12 weeks]
The nurse will observe how many patients may have adverse effects.
Health-related effects on quality of life. [12 weeks]
Patients will answer the European Quality of Life-5 Dimension. This consists of a questionnaire to measure health-related quality of life, before and after the treatment. This scale have two parts: in the first one, 0 is the best score; and 15 is the worst. In the second part (that is a pain rating scale): 0 is the worst state of health imaginable and 10 the best state of health imaginable.
