ABSTRACT
OBJECTIVE:
To determine the effect of dietary protein on healing of pressure ulcers in malnourished patients.DESIGN:
Nutritional intervention trial with the non-randomized assignment of patients by pressure ulcer stage and bed type.SETTING:
Long-term care facility. PATIENTS Twenty-eight malnourished patients (age = 72 +/- 18 years, mean +/- SD) with a total of 33 truncal pressure ulcers. Nine patients had stage II ulcers, eight had stage III ulcers, and 16 had stage IV ulcers.METHODS:
Patients received liquid nutritional formulas as tubefeedings or meal supplements containing either 24% protein (61 g protein/L; n = 15) or 14% protein (37 g protein/L; n = 13) for 8 weeks.RESULTS:
There was a significant decrease in total truncal pressure ulcer surface area of the 15 patients in the 24% protein group (-4.2 +/- 7.1 cm2, P < 0.02), but not in the 13 patients in the 14% protein group (-2.1 +/- 11.5 cm2, P = NS). The change in total ulcer area correlated with both dietary protein intake per kg body weight (rs = -0.50, P < 0.01) and caloric intake per kg body weight (rs = -0.41, P < 0.03). The decrease in stage IV ulcer area in eight patients in the 24% protein group (-7.6 +/- 5.8 cm2, P < 0.02) was significantly greater (P < 0.05) than in eight patients in the 14% protein group (-3.2 +/- 16.4, P = NS). In these 16 patients, the decrease in ulcer size also correlated with dietary protein intake per kg body weight (rs = -0.63, P < 0.01).CONCLUSION:
High protein diets may improve the healing of pressure ulcers in malnourished nursing home patients.
