Efficiency, cost-effectiveness and need of inversion in nutritional therapy. Importance of detecting and documenting undernutrition

SummaryDisease Related Malnutrition (DRM) is highly prevalent in Spanish hospitals. WHO estimates that 20–40% of health-associated expenses are lost due to inefficiency. Demonstration that DRM is a component of inefficiency and hiring a specialist physician for its detection and treatment is cost-effective.Material and methodsComparison between nutritional diagnosis and procedures detected and encoded at discharge using McNemar test. Recoding of 162 discharge reports including nutritional diagnoses and procedures. Determine changes on Case-Mix Index (IC), cost of procedure and cost procedure/DRG index. Comparison using T-student paired test.ResultsOnly 10 of 162 diagnoses of malnutrition were coded in delivery statements (p < 0.001). After right codification, IC increased in 103,3 DRG points (p < 0.001). Consequently, procedure cost/DRG index was reduced in 978.81 € (p < 0.001).ConclusionsDRM is underdiagnosed in our hospital.DRM and nutritional procedures detection by a doctor specialist in clinical nutrition led to a reduction in cost procedure/DRG index of 16.8% of officially established by the Health System. Loss of 16.8% of health expenses, estimated in 424.785,15 € was described. Proper codification would have justified 343.291,2 € reimbursement just for nutritional diagnoses and processes. Both expenses were lost due to system's inefficiency. Those amounts are much higher than cost associated of hiring a specialist in clinical nutrition.
