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.

BACKGROUND: Acute alcohol consumption and chronic alcohol consumption increase the burden placed on emergency departments (EDs) by contributing to injury and disease. Whether the prevalence of alcohol-related ED visits in the United States has changed in recent years is unknown. The purpose of this study was to examine trends in ED visits involving acute and chronic alcohol consumption in the United States by age and sex between 2006 and 2014. METHODS: Data from the Nationwide Emergency Department Sample (NEDS), the largest all-payer ED database in the United States involving 945 hospitals in 33 states and Washington, DC, were analyzed to assess changes in prevalence and rates of ED visits involving acute and chronic alcohol consumption by age and sex over time among persons aged ≥12 between 2006 and 2014. RESULTS: Between 2006 and 2014, the number of ED visits involving alcohol consumption increased 61.6%, from 3,080,214 to 4,976,136. The rate increased 47% from 1,223 to 1,802 per 100,000 population and the total cost of such visits increased 272% from $4.1 billion to $15.3 billion. The number of acute alcohol-related ED visits increased 51.5% from 1,801,006 to 2,728,313 and the rate increased 40% from 720.9 to 1,009.6 per 100,000 population. The number chronic alcohol-related visits increased 75.7% from 1,279,208 to 2,247,823 and the rate increased 57.9% from 502.2 to 792.9 per 100,000. The annual percentage change in rates of all alcohol-related ED visits was larger for females than for males (5.3% vs. 4.0%). Other drug involvement increased the likelihood of admission for inpatient treatment. CONCLUSIONS: Alcohol consumption contributed to an increasing number of ED visits in the United States between 2006 and 2014, especially among females. Increased utilization of evidence-based interventions is needed.
