Previous studies have documented the importance of clinical, functional, and cognitive variables for in-hospital mortality risk, but their frequency and importance in Latin American populations is yet to be described. It is important because Colombia has multiple ethnic races, with different types of longevity, and we have a history of social violence that affects our life expectancy. The aim of this study is to define which risk factors are associated with in-hospital mortality in octogenarians, and how frequent they are and quantify the weight of each of these factors in the outcomes.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methodology:<\/jats:title>\n                    <jats:p>We present an analytical observational retrospective cohort study in adult patients over 80\u2009years of age hospitalized and followed by the geriatrics service at Hospital Universitario San Ignacio (Bogot\u00e1, Colombia).

Malnutrition was documented in 22.4%, dependency for basic activities (Barthel\u2009\u2a7d\u200995) in 75.9%, and positive screening for frailty (FRAIL\u2009\u2a7e\u20093) in 55.3%.
