|Abstract:||This systematic review assessed whether nutritional screening tools (NSTs) predict mortality, functional decline, and move to higher level care in older adults residing in the community or in institutions. In total, 37 prospective studies published between 1999 and 2012 met inclusion criteria and were included in this review. The most commonly used NST in these studies was the Mini Nutritional Assessment (MNA). Comparison of NSTs was limited by variation in follow-up time, lack of uniform definition of functional decline, and biases in many studies. Results of MNA, MNA-Short Form (MNA-SF), and Geriatric Nutrition Risk Index (GNRI) assessments were significantly associated with subsequent mortality, with good negative predictive power (~0.83), but only modest positive predictive power (PPV~0.32). MNA-SF and MNA results had a low to moderate association with functional decline (PPV~0.34). Move to higher level care was less strongly associated with NST scores (PPV~0.25). Overall, there is evidence that NSTs can predict those at low risk of mortality, functional decline, and, to a lesser extent, move to higher level care in older people|
