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

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.
