The goal of this observational study is to compare the differences in wound outcomes when the MolecuLight imaging procedure is used in combination with standard of care wound assessment in long term care and skilled nursing facilities. The main outcome studied is healing of ulcers after 12-weeks, along with other outcomes such as occurrence of infection, complications, and antimicrobial use. Medical records from the past were reviewed, where patients receiving the MolecuLight procedure were compared to those who did not.
