Protein calorie malnutrition (PCM) is common and often undiagnosed in older adults. Left untreated, PCM carries both clinical and financial risks, including decreased quality of life, declining functionality, the inability to live independently, and increased health care costs. The prevalence of PCM in older adults calls for a systematic and standardized approach to nutrition screening that includes the use of a validated screening tool. Recommended by international organizations, the Mini Nutritional Assessment® (MNA) is highly specific and reliable and the most well-validated nutrition screening tool for adults 65 and older. Simple, noninvasive, inexpensive, and easy for nurses and other clinicians to use, the newest MNA-short form (MNA-SF) can quickly and easily identify older adults who are at risk for malnutrition or malnourished. Nurses are key players in successful malnutrition screening in hospitals, long-term care, home care, and community settings. It is strongly recommended that nurses incorporate the newest MNA-SF into all practice settings where older adults receive care.
