“…The nutritional control tool (CONUT) defines the degree of malnutrition based on the circulating concentrations of albumin, total cholesterol and lymphocytes, and their relation between elderly patients and the exceed hospital stay, premature readmissions, and the associated cost (Redondo, Navalon, Canovas, Jimenez, & Alvarez, 2015). Prospective studies (Badosa et al, 2017;Ballesteros-Pomar et al, 2016;Torres et al, 2018) focus on relating the degree of malnutrition obtained with the malnutrition universal screening tool, with LOS, mortality, and readmission. The two systematic reviews by Rodriguez-Manas, Abizanda, Barcons, and Lizan (2014) and by Abizanda, Sinclair, Barcons, Lizan, and Rodriguez-Manas (2016) include studies conducted in Europe and showed that the total costs associated with malnutrition in institutionalized older adults living in the community were considerably higher than those of well-nourished people, mainly due to a greater use of medical care resources (general practitioner, consultations, hospitalizations, monitoring of medical attention, and treatments).…”
