Abstract
BACKGROUND: We evaluated a new bed that updates the functionality of the current air fluidized therapy (AFT)/continuous low-pressure (CLP) pressure redistributing beds. This bed was evaluated in conjunction with standard wound care interventions in a long-term acute care hospital (LTACH). The AFT feature is designed to provide pressure distribution via a fluid-like medium that forces air though millions of tiny silicone beads that float the patient's body to achieve maximum immersion and envelopment. The CLP feature of the bed provides pressure distribution for the upper body. Standard wound care was provided that included debridement, topical treatments, and biophysical therapies such as negative pressure wound therapy, as indicated.
CASES: Our multiple case series comprised 10 medically compromised patients with 25 wounds. Their mean age was 63 years, 50% were male, and the mean cumulative Braden Scale score was 12.4 out of 23, indicating a high risk for pressure injury (PI). Seven of 10 patients were incontinent of urine, 6 had fecal incontinence, and 2 had ostomies. Types of wounds treated included 2 large tissue defects from surgical excisions for the treatment of gangrene and 23 PIs. On admission, wounds had an average surface area of 139.1 cm2. The mean percentage of reduction in wound surface area was 59.3% over an average of 31.3 days of therapy. No new wounds formed during their course of care despite being at elevated risk.
CONCLUSIONS: Findings from this multiple case series suggest that the AFT/CLP bed facilitates healing of advanced wounds in medically complex patients when included as part of a wound care program. Despite mild to high risk, no new PIs developed, and severe PIs and large tissue defects significantly improved or completely resolved. One hundred percent of surveyed staff members recommend use of the AFT/CLP bed.
