Incidence and criteria used in the diagnosis of hospital-acquired malnutrition in adults: a systematic review and pooled incidence analysis

Research and exploration of quality control indicators for nutritional therapy in critically ill patients-a multicenter before-and-after controlled study

Objective

To evaluate and explore the feasibility of using quality control indicators for nutritional therapy in critically ill patients as quality evaluation criteria.

Methods

This study focused on intensive care unit (ICU) critically ill patients and conducted a cross-sectional investigation of nutritional therapy quality control indicators (the proportion of patients with application of enteral nutrition pump, nutritional risk assessment rate, the proportion of patients start enteral nutrition within 48 hours, and caloric and protein target achievement rate on 7th day) in 13 hospitals in Jilin Province. After training according to the critical patients nutrition related guidelines and the latest literatures, a second cross-sectional investigation was conducted. Then, analyze the improvement of quality control indicators of the nutritional therapy before and after the training, thus evaluating the feasibility of using these quality control indicators as nutritional therapy quality evaluation criteria in critical patients.

Results

(1) A total of 631 patients were included before and after training, with a data acquisition rate of 97.3% for enteral nutrition pumps usage and complete data collection for the remaining nutritional risk assessment rate, start enteral nutrition proportion of patients within 48 h, and caloric and protein target achievement rate on 7th day. (2) The nutritional risk assessment rate before and after training was 88.2% vs. 94.8%, with a P-value of 0.003. The proportion of patients start enteral nutrition within 48 h before and after training was 65.1% vs. 75.4%, with a P-value of 0.039; and protein target achievement rate on 7th day before and after training was 64.6% vs. 79.6%, with a p-value of 0.015. These five indicators as quality evaluation criteria are relevant to the current developments in nutritional therapy and consistent with the national conditions of China. The proportion of patients with application of enteral nutrition pump before and after training was 70.1% vs. 79.4%, with a p-value of 0.065, and the caloric target achievement rate on 7th day before and after training was 73.4% vs. 83.9%, with a p-value of 0.062, and there was no statistical difference between the two groups.

Conclusion

The five quality control indicators for nutritional therapy in critically ill patients are clinically feasible and can be used as quality evaluation criteria for nutritional therapy in critically ill patients.

Incidence and outcomes of in-hospital nutritional decline: A prospective observational cohort study in adult patients

BACKGROUND AND AIMS

Hospital malnutrition is associated with higher healthcare costs and worse outcomes. Only a few prospective studies have evaluated trends in nutritional status during an acute stay, but these studies were limited by the short timeframe between nutrition assessments. The aim of this study was to investigate changes in nutritional status, incidence of hospital-acquired malnutrition (HAM), and the associated risk factors and outcomes in acute adult patients admitted for >14 days.

METHODS

A prospective observational cohort study was conducted in two medical and two surgical wards in a tertiary hospital in Brisbane, Australia. Nutrition assessments were performed using the Subjective Global Assessment at baseline (day eight) and weekly until discharge. Nutritional decline was defined as a change from well-nourished to moderate/severe malnutrition (HAM) or from moderate to severe malnutrition (further decline) >14 days after admission.

RESULTS

One hundred and thirty patients were included in this study (58.5% male; median age 67.0 years (IQR 24.4), median length of stay 23.5 days (IQR 14)). At baseline, 70.8% (92/130) of patients were well-nourished. Nutritional decline occurred in 23.8% (31/130), with 28.3% (26/92) experiencing HAM. Of the patients with moderate malnutrition on admission (n = 30), 16% (5/30) continued to decline to severe malnutrition. Improvement in nutritional status from moderate and severe malnutrition to well-nourished was 18.4% (7/38). Not being prescribed the correct nutrition care plan within the first week of admission was an independent predictor of in-hospital nutritional decline or remaining malnourished (OR 2.3 (95% CI 1.0-5.1), p = 0.039). In-hospital nutritional decline was significantly associated with other hospital-acquired complications (OR 3.07 (95% CI 1.1-8.9), p = 0.04) and longer length of stay (HR 0.63 (95% CI 0.4-0.9), p = 0.044).

CONCLUSION

This study found a high rate of nutritional decline in acute patients, highlighting the importance of repeated nutrition screening and assessments during hospital admission and proactive interdisciplinary nutrition care to treat or prevent further nutritional decline.
