Fluid Immersion Simulation (FIS) System Versus Air Fluidized Bed (AFB) System for Pressure Ulcers

Northwestern University80 enrolled

Overview

The primary objective is to compare the efficacy of the FIS on closure rate to the AFB after 2 weeks of operative debridement and closure.

Secondary Objectives: 1. Compare the complication rate in each treatment group during the acute postoperative period (2 weeks). 2. Comparisons of the inflammatory and bacterial microbiomes of pressure ulcers following surgical therapy. 3. Comparisons of baseline patient characteristics and their relationship to both early and late pressure ulcer recurrence, and complication rates. 4. Assessment of outcomes and complications associated with flap technique and surgeon guided descriptions of the operative closure. 5. Compare the absolute costs associated with the FIS System against AFB system. 6. Compare the acceptance of each system by subjects and nursing staff, including the parameter of patient comfort at 7 and 14 days postoperative. 7. Assessing the incidence of complications and additional treatments needed following the two week study period.

Outcomes

Primary Outcomes

Percentage of Participants With Successful Closure of Wound at 2 Weeks After Surgery

Comparison of success of closure between treatment groups.

Time frame: 2 weeks

Secondary Outcomes

Number of Participants With Complications

Comparison of complication rate, including dehiscence, necrosis, maceration, and seromas between treatment groups. These are gathered via the patient's medical chart and interaction with the Principle Investigator (their physician).

Time frame: 2 weeks

Differences in Quantitative Patient Survey Responses: Acceptability

Differences in quantitative patient survey responses regarding acceptability. This scale includes three subscales: 1) comfort, 2) difficulty with mobilization, and 3) pain at surgical site. Each subscale is graded on a scale of 1-5 with 1 being "better" (i.e. very comfortable, no difficulty, or no pain) and 5 being "worse" (i.e. very uncomfortable, extreme difficulty, or extreme pain). Subscales will be combined to compute a total score by averaging the sum of each of the three subscales. The total score indicates patient acceptability on a scale of 1-5 with 1 being "better" (very acceptable) and 5 being "worse" (not acceptable).

Time frame: 2 weeks

Differences in Quantitative Nurse Survey Responses

Differences in quantitative nurse survey responses regarding acceptability and tolerance of each therapeutic modality, including patient comfort. This survey includes three subscales: 1) ease of use, 2) amount of training required, and 3) Time Required for Troubleshooting or Otherwise Occupied by Device. Each subscale is graded on a scale of 1-5 with 1 being "better" (i.e. no difficulty, no training, or no time) and 5 being "worse" (i.e. extreme difficulty, very high amount of training, or \>30 minutes a day). Subscales will be combined to compute a total score by averaging the sum of each of the three subscales. The total score indicates nurse acceptability on a scale of 1-5 with 1 being "better" (very acceptable) and 5 being "worse" (not acceptable).
