Use of Low-level Laser Therapy in the Treatment of Incontinence-associated Dermatitis in the Elderly

Incontinence-associated dermatitis (IAD) is defined as skin inflammation resulting from prolonged exposure to feces and/or urine, found in individuals with urinary incontinence, fecal incontinence, or both. Currently, preventive and treatment measures with strong clinical evidence include gentle hygiene and application of barrier products. Justification: Low-Level Laser Therapy (LLLT) is used in the tissue repair process, due to its analgesic, anti-inflammatory and biomodulator effects, with improvement in the treatment of pressure injuries. In this way, would the use of LLLT bring better results associated with topical treatment for the management of IAD?

Study Overview

• Status: Completed
• Conditions: Dermatitis
• Intervention / Treatment: Other: Gentle intimate hygiene and skin protective barrier application - Persistent erythema with intact epidermis; Other: Low Level Laser Therapy - Persistent erythema with intact epidermis; Other: Gentle intimate hygiene and skin protective barrier application - Erythema with signs of epidermis loss; Other: Low Level Laser Therapy - Erythema with signs of epidermis loss

Detailed Description

This is a field study, analytical, interventionist, controlled clinical trial type, randomized, double-blind and with quantitative data analysis, with the aim of comparing the topical treatment of Incontinence-Associated Dermatitis in the elderly with the topical treatment associated with Low Intensity Laser Therapy. The study population will consist of elderly people with Incontinence-Associated Dermatitis admitted to a surgical and semi-intensive medical clinic of a private, tertiary, extra-sized hospital, located in the south zone of the city of São Paulo.

Participants will be divided initially by the characteristics of IAD: persistent erythema with intact epidermis and erythema with signs of epidermis loss. Subsequently, randomization will be performed using the REDCap platform and participants will be divided into Control Group and Experimental Group.

The Control Group will receive the conventional treatment and the Experimental Group will receive the conventional treatment associated with the application of Low Intensity Laser Therapy. The conventional treatment of patients belonging to both groups will be made available in the institutional protocol of the study site for the treatment of Incontinence-Associated Dermatitis, according to its characteristics of persistent erythema with intact epidermis or erythema with signs of epidermis loss.

Persistent erythema with intact epidermis: Perform intimate hygiene with warm water (to remove excess feces and urine), apply skin cleanser without rinsing to finish cleaning, apply a thin layer of Dexpanthenol (with each diaper change), apply polymeric solution spray once a day.

Erythema with signs of epidermis loss: Perform intimate hygiene with warm water (to remove excess feces and urine), apply a leave-in skin cleanser to finish cleaning, apply powdered hydrocolloid powder and remove excess. Afterwards, apply a polymeric spray solution.

For the application of LLLT, laser therapy equipment will be used with a wavelength of 660nm and 808nm, power of 100mW, with category 3R and within the institution's calibration period.The entire area affected by DAI will be irradiated with LBI at 1 Joule (J) of energy and with a wavelength of 660nm and 1J with a wavelength of 808nm, which will be applied simultaneously, with a radiance of 20J/cm2 per point, the distance between the stitches will be 1cm long and the application of LLLT will be performed every 24 hours.

Study participants will be followed up with daily visits for four days. On the first and fourth day of follow-up, a photographic record of the area affected by IAD will be taken and it will be assessed whether the participant has pain (verbal or numerical scale or PANAID scale) in the region affected by IAD during intimate intercourse. hygiene. Both groups will receive standardized topical treatment at the institution, according to the characteristics of the DAI and the participants of the Experimental Group will receive the application of low-intensity laser therapy in the area affected by the DAI for three days.

Follow-up may be interrupted before four days in the following cases: if the IAD is resolved, if the participant is discharged from the hospital, if the participant is transferred to intensive care or oncology during the study period, if the nursing staff changes the conduct of the proposed treatment, if the physician changes the proposed treatment or if the participant refuses to remain in the study or if the participant is diagnosed with COVID-19.

Three specialist judges, stoma therapist nurses with more than five years of experience in stoma therapy, will evaluate the photographic records of the first and last day and will evaluate: the percentage of area affected by DAI, the percentage of area affected by erythema, the percentage of area affected by erosion, percentage of area affected by denudation/ulceration, percentage of area affected by papules/satellite lesions, percentage of area affected by maceration. The evaluators will not know if the photo is from the first or the last day of treatment, they will not know the proposed treatment and they will not know about the evaluation of the other evaluator.

Through the results of the verbal and numerical scale or PANAID obtained on the first and last day of follow-up, it will be verified whether or not there was an improvement in pain during intimate hygiene in the area affected by IAD.

With the results of the specialists' evaluations of the first and last day of follow-up, it will be verified whether or not there was an improvement in the characteristics of the IAD, verifying the effectiveness of the proposed treatment.
