Improvement of the nutritional support management system for patients in intensive care units.

ABSTRACT

BACKGROUND: Nutritional support for patients hospitalized in the intensive care unit (ICU) is an important part of clinical treatment and care, but there are significant implementation difficulties. AIM: To introduce a modified nutritional support management system for ICU patients based on closed-loop information management and psychological counseling. METHODS: The division of functions, personnel training, system construction, development of an intelligent decision-making software system, quality control, and improvement of the whole process were carried out to systematically manage nutritional support for ICU patients. RESULTS: Following the implementation of the whole process management system, the scores of ICU medical staff's knowledge, attitudes/beliefs, and practices regarding nutritional support were comprehensively enhanced. The proportion of hospital bed-days of total enteral nutrition (EN) in ICU patients increased from 5.58% to 11.46%, and the proportion of EN plus parenteral nutrition increased from 42.71% to 47.07%. The rate of EN initiation within 48 h of ICU admission increased from 37.50% to 48.28%, and the EN compliance rate within 72 h elevated from 20.59% to 31.72%. After the implementation of the project, the Self-rating Anxiety Scale score decreased from 61.07 ± 9.91 points to 52.03 ± 9.02 points, the Self-rating Depression Scale score reduced from 62.47 ± 10.50 points to 56.34 ± 9.83 points, and the ICU stay decreased from 5.76 ± 2.77 d to 5.10 ± 2.12 d. CONCLUSION: The nutritional support management system based on closed-loop information management and psychological counseling achieved remarkable results in clinical applications in ICU patients.
