Malnutrition, Dysphagia, Sarcopenia and Weakness in the Older Population: A Retrospective Review to Enlighten Future Directions for Health System Best Practices.

The older population is growing exponentially causing greater demands on healthcare. Malnutrition, dysphagia, sarcopenia and weakness are highly prevalent diseases in the older population. Previous research (Byun et al. in BMC Geriatr 19(356):1-7, 2019; Fujishima et al. in Geriatr Gerontol Int 19:91-97, 2019; Hernandez et al. in Nutr Hosp 32(4):1830-1836, 2015; Nagano et al. in J Nutr Health Aging 23(3):256-265.5, 2019; Nishioka et al. in Clin Nutr 36(4):1089-1096, 2017; Robinson et al. in Clin Nutr 37(4):1121-1132, 2018, https://doi.org/10.1016/j.clnu.2017.08.016 ) has shown that these disorders are frequently associated, in many cases, preventable using screenings and intervention. This study utilized the National Hospital Discharge Survey of 2008 from the National Center of Health Statistics as secondary data to examine the associations amongst these four variables as well as possible correlations with age, days of care in the acute care hospital setting and frequency of rehabilitative and nutritional interventions received by these patients. Out of 165,630 cases, a sample size of 59,029 cases ages 65 and above were filtered by the researchers for desired diagnoses and procedure codes. After this, all neurological diagnoses were filtered and excluded by the researchers, resulting in 2458 cases. Using the Chi square test of independence, findings revealed significant associations between the variables of malnutrition and dysphagia (χ
