Financial implications of malnutrition.
PEM or the possibility of developing PEM occurs in 30% to 50% of hospitalized patients, the frequency determined by the criteria used in its assessment and the case mix of patients in the hospital population. This condition exists independently of other medical conditions and results from preadmission or postadmission failure to meet nutrient requirements with associated loss of body weight and function, as well as impaired immunity. PEM also frequently arises in patients with a chronic condition and decreased functional reserve when a superimposed acute metabolic stress leads to accelerated nutrient depletion. Whether preexisting or not, PEM increases morbidity and mortality along with LOS and may be associated with complications such as pneumonia, sepsis, operative site infection, delayed wound healing, or decubitus ulcers. The cost of these complications and an extended LOS is a significant financial burden and a controllable medical liability for hospitals. Other costs include identifying patients at risk of PEM, providing nutrition support, not to mention treating any of its complications (mechanical, metabolic, and so forth). A proper analysis of the financial implications of late or untreated PEM versus nutrition support must therefore take into account not only the costs of complications or extended LOS due to the delay or failure to provide nutrition support but also the costs associated with this intervention itself. In this review, we described a model for examining the financial implications of malnutrition and nutritional therapy.
