A Single Long-Term Acute Care Hospital Experience with a Pressure Ulcer Prevention Program.

PURPOSE: The occurrence of pressure ulcers (PrUs) challenges care facilities. Few studies report PrU reduction efforts in long-term acute care (LTAC). This study described the PrU reduction efforts of a single, LTAC facility using the Medline Pressure Ulcer Prevention Program (mPUPP). DESIGN: This study was a quasi-experimental, quality improvement project, with pre- and postmeasurement design. METHODS: Outcomes were tracked for 24 months. The mPUPP was implemented in month 11. Education for caregivers was provided through an interactive web-based suite. In addition, all Patient Care Technicians attended a 4-week 1-hour inservice. New skin care products were implemented. The facility also implemented an algorithm for treatment of wounds. FINDINGS: There was a significant reduction in the mean monthly hospital-acquired PrU (nPrU) rate when preprogram is compared to postprogram. CONCLUSIONS: Sustainable nPrU reduction can be achieved with mPUPP. CLINICAL RELEVANCE: LTAC hospitals could expect to reduce nPrU with education and incentive of caregivers.

Effects of beta-hydroxybutyrate on cognition in memory-impaired adults.

Glucose is the brain's principal energy substrate. In Alzheimer's disease (AD), there appears to be a pathological decrease in the brain's ability to use glucose. Neurobiological evidence suggests that ketone bodies are an effective alternative energy substrate for the brain. Elevation of plasma ketone body levels through an oral dose of medium chain triglycerides (MCTs) may improve cognitive functioning in older adults with memory disorders. On separate days, 20 subjects with AD or mild cognitive impairment consumed a drink containing emulsified MCTs or placebo. Significant increases in levels of the ketone body beta-hydroxybutyrate (beta-OHB) were observed 90 min after treatment (P=0.007) when cognitive tests were administered. beta-OHB elevations were moderated by apolipoprotein E (APOE) genotype (P=0.036). For 4+ subjects, beta-OHB levels continued to rise between the 90 and 120 min blood draws in the treatment condition, while the beta-OHB levels of 4- subjects held constant (P<0.009). On cognitive testing, MCT treatment facilitated performance on the Alzheimer's Disease Assessment Scale-Cognitive Subscale (ADAS-cog) for 4- subjects, but not for 4+ subjects (P=0.04). Higher ketone values were associated with greater improvement in paragraph recall with MCT treatment relative to placebo across all subjects (P=0.02). Additional research is warranted to determine the therapeutic benefits of MCTs for patients with AD and how APOE-4 status may mediate beta-OHB efficacy.

Chronic wounds treated with a physiologically relevant concentration of platelet-rich plasma gel: a prospective case series.

Chronic wounds are characterized by a long inflammatory phase that hinders regenerative wound healing. The purpose of this prospective case series was to evaluate how a physiologically relevant concentration of an autologous platelet-rich plasma (PRP) gel affects initial wound healing trajectories of chronic, nonhealing wounds of various etiologies and in different care settings. Using convenience sampling methods, 49 patients (average age: 60.6 years, SD 14.7) with 65 nonhealing wounds (mean duration 47.8 weeks, range 3 to 260) at eight long-term acute care (LTAC) hospitals and three outpatient foot or wound clinics who were prescribed PRP gel for their nonhealing wound were enrolled. The majority of patients had low albumin, hematocrit, and/or hemoglobin levels. After wound assessments and measurements were obtained and the gel prepared, a skin barrier was applied to the periwound skin and the gel applied and protected with cover dressings. The most common wounds were pressure ulcers (n = 21), venous ulcers (n = 16) and diabetic foot ulcers (n = 14). Mean wound area and volume were 19 cm2 (SD 29.4) and 36.2 cm3 (SD 77.7), respectively. Following a mean of 2.8 (SD 2.4) weeks with 3.2 (SD 2.2) applications, reductions in wound volume (mean 51%, SD 43.1), area (39.5%, SD 41.2), undermining (77.8%, SD 28.9), and sinus tract/tunneling (45.8%, SD 40.2) were observed. For all wound etiologies, 97% of wounds improved. The results of this study suggest the application of this PRP gel can reverse nonhealing trends in chronic wounds.
