AFT/CLP-LAL RCT Stage 3 or 4 Pressure Injuries

Overview

Patients who have at least one stage 3 or 4 PI and are admitted to a participating treating facility will be candidates for study enrollment. Patients must provide written informed consent. Standard care for their admitted condition will be provided for the patients except for support surface selection, laboratory blood tests, PI measurement(s) by the 3-D camera measurement tool, and added pain and patient satisfaction assessments. Clinical assessments will be recorded weekly as described below. Patients will be followed until discharge from the LTACH or until 1) they require a different mattress for their admitted condition; or 2) reach a maximum of 12 weeks in the LTACH. At study discontinuation, a clinical general assessment of the quality of improvement of the PIs will be recorded.

Patients admitted to the LTACH with at least one stage 3 or 4 PI will be evaluated for possible inclusion/exclusion criteria. Patients will be approached by the investigator, or their designee to acquire patient informed consent. If provided, patients will be randomized to their designated support surface, the bed will be ordered and patients will begin the study with a baseline study visit (week 0) that will include: * Date and time of study bed placement * A brief medical history, that includes current diagnoses, assessment of co-morbidities, an assessment of neurologic status, nutritional status, level of mobility, history of current PI's, documentation of treatments that have been applied to PI(s) prior to study entry * Braden PU risk assessment (overall and subscores) * Assessment of pain associated with the PI using a pain numeric rating scale (NRS), where patients rate their current pain intensity from 0 ("no pain") to 10 ("worst possible pain") \[21\] * Blood for CBC, Albumin, Pre-Albumin, CRP will be collected. * PI assessments: all PI's located on the lower truncal region of the patient's body will be assessed both subjectively by the treating clinicians for clinical signs of infection, as well as by a 3D wound assessment tool. * Overall health status assessment Subsequent weekly study visits will continue for a maximum of 12 weeks. The interim study visit documentation will include: * Overall health status assessment of health (whether the patient's health is improving, maintaining, or worsening) * Skin assessment to document any new PI's that may have developed, * Braden PU risk assessment (overall and subscores) * 3D Wound assessments of all lower truncal PI's, * Clinical Assessment of signs and symptoms of wound infection * Confirmation of support surface type, * Documentation of adverse device effects, device-related complaints (within 24 hours of effect/complaint). Clinical Resource Utilization Data: documentation of the following data will aim to achieve estimated clinical resources associated with caring for PIs: * Documentation of dressing supplies, * Debridement method, duration and frequency * Type of antibiotics dosage, frequency, and duration * Other pharmacologic agents used for wounds with dosage, frequency, and duration * Assessment of pain * Rental bed cost estimates * Documentation of professional healthcare visits and/or types of healthcare services in the preceding week. * Documentation of acute care hospitalizations * An estimate of LTACH staff time devoted to wound care per day for that study week. At study discharge, which may occur at the time of study PI healing, LTACH discharge, or upon stepdown from the randomized study surface) or for other reasons, a final study visit will be completed that includes: * Date and time of study bed removal * Overall health status assessment, * Skin assessment to document any new PI's that may have developed, * Braden PU risk assessment (includes subscores), * 3D wound assessments of all truncal PI's, * Clinical assessment of signs and symptoms of wound infection * Confirmation of bed support surface type * Documentation of adverse device effects, device related complaints (within 24 hours of effect/complaint). * Clinical Resource Utilization Data: * documentation of dressing supplies, * debridement method, duration and frequency * type of antibiotics, dosage, frequency, and duration * other pharmacologic agents used for wounds with dosage, frequency, and duration, * rental bed cost estimates * documentation of professional healthcare visits and/or types of healthcare services in the preceding week. * documentation of acute care hospitalizations * an estimate of LTACH staff time devoted to wound care per day for that study week. * Assessment of pain * A patient bed satisfaction assessment will be completed if the patient is able to communicate * Blood for CBC, Albumin, Pre-Albumin, CRP will be collected
