Registration Number

Lead Sponsor
Guadarrama Hospital
Brief Summary

Introduction: Chronic wounds are a major health problem with impact in the quality of life of patients, increased their morbidity and mortality, nursing burden, extend the hospital stays, and healthcare costs. Searching how to apply the best care available in wounds, shock wave treatment is found in order to stimulate tissue growth in this type of skin injuries. There are different studies to support this recommendation but also there is variability about of patients, different types of injuries or settings. It is considered that more research studies are needed to maintain this evidence and to explore other settings like the effectiveness in a medium stay hospital.

Objectives: To assess the effectiveness of shockwave treatment to reduce the size of chronic wounds.

Method: A quasi-experimental design will be used. The population under study will include patients admitted in the Functional Recovery Unit who present chronic wounds upon admission. The sample size will be 30 patients. An intentional non-probabilistic sampling will be carried out. Main outcome: decrease the wound size. Sociodemographic variables, personal history, comorbidities, current clinical situation, shock wave treatment variables and its evolution will be collected.

Applicability: In case of findings are better than habitually care, the number of treatments required by the patient would be reduced, the patient's state of health would improve, the risk of infection of the wound decrease, and the comfort and quality of life of patients could improve. The findings may represent a change in clinical practice because they may be used to modify the treatment protocols for chronic wounds at the Guadarrama Hospital and in other similar hospitals. Also, they can contribute to the evidence based care which supports shockwave treatment.

Detailed Description

Recruitment: the research team will recruit participants who meet inclusion criteria and do not present exclusion criteria, during the first 48 hours of admission to the functional recovery unit. A member of the team will inform and invite the subject or his or her legal representative to participate in the study. The information sheet will be given to the patient and after accepting, he/she has to sign the specific informed consent for the study and the authorization to take images. At that time, the completion of the Data Collection Notebook will begin, which has been prepared ad hoc by the research team. In order to guarantee the confidentiality of the personal data, they will be coded by dissociating the identifying and personal data from those necessary for the configuration of variables. To this end, the personal identity carry out a coding process of the units of analysis. In the event that the same patient has more than one wound that can be included in the study, a data collection notebook will be used for each wound, indicating its location and using the same coding, because the coding number will be associated with each patient.

Extracorporeal Shockwave TherapyExtracorporeal Shockwave TherapyThe parameters for shock wave therapy will be: frequency 4-6 Hz, intensity 0.075-0.11 mJ/mm2 (millijoules per millimeter), number of pulses 350+10xcm2 (square centimetre) of wound surface (the number of pulsations is dependent of the surface), with sterile field (sterile gel on the wound and sterile transparent film to cover it). They will be applied by sweeping the surface of the wound and 1 centimetre around it. In each session, the session-specific data notebook and the appearance of side effects (pain, bleeding, others) will be recorded. Subsequently, the conventional healing procedure will be applied, according to the procedures for healing chronic wounds of the Guadarrama Hospital.
Primary Outcome Measures
NameTimeMethod
Decrease wound size areaAll wounds will be measured at the end of the intervention (3 weeks).

Decrease de size area at the end of the intervention. The surface of the wound will be measured in centimeters (length x width)

Secondary Outcome Measures
NameTimeMethod
To quantify the change in the size of chronic wounds treated with shock wavesat the end of the intervention (3 weeks)

The surface of the wound will be measured in centimeters. The average of the decrease will be evaluated.

To assess whether the pain perception due to chronic wounds in patients undergoing the intervention decreases. The pain perception will be measured with Visual Analogue Scale (VAS) or Pain Assesment in Advanced Dementia Scale (PAINAD).Baseline and during the intervention (up 3 weeks)

Pain will be assessed baseline and during the shockwave session with Visual Analogue Scale (VAS) or Pain Assesment in Advanced Dementia Scale (PAINAD). The tool will be used depending on the patients' cognitive status. VAS and PAINAD scales measure fron 0 to 10 being 0 without pain and 10 the worst pain possible.

To identify the patients variables related to achieve a lesion reduction equal to or greater than 50% of the surface measured in centimeters (greater success in healing).at the end of the intervention (3 weeks)

The demographic (aged, sex) and clinic (urinary incontinence, faecal incontinence, personal history, Barthel Index, Norton Scale, blood albumin, smoking habits, type of wound, location of wound, clinical course) variables will be compared with the main variable

To assess number and types of side effects what patients shows related to the use of low-frequency shockwaves in chronic wounds.at the end of the intervention (3 weeks)

Side effects (none, bleeding, skin redness, red spots, vasovagal syncope, paresthesia, hypesthesia, others) will be collected after the sessions.
