Objective: To determine the clinical epidemiological indicators associated with pressure ulcers (UPP) in patients of the Medicine Service of the Hipólito Unanue National Hospital during the years 2016-2017. Methods: Observational, analytical and retrospective study, based on the review of medical records. A non-probabilistic sample was obtained for convenience, calculating the odds ratio (OR), applying the 95% confidence interval and using the chi square test, with a value of p <0.05 as statistically significant. Results: For the sample, 93 patients were obtained who fulfilled the study criteria; 50.5% were male, with an average age of 68 years (+21 years), with 74.19% of the total population being older adults. The most frequent locations of UPP were at the sacral level (77%) and heel (12.9%); likewise, the most frequent stages were: II (32.3%), IV (31.2%) and III (26.9%). The presence of severe UPP was associated to: being older (OR: 3.12, 95% CI: 1.2-8.2), hypoalbuminemia (OR: 6.23, 95% CI: 1.8-21.1), anemia (OR: 4.31, 95% CI: 1.2- 14.9) and lymphopenia (OR: 3.68, 95% CI: 1.5-9). Conclusion: Elderly patients with hypoalbuminemia, anemia or lymphopenia are at greater risk of developing severe pressure ulcers, which significantly interfere with their quality of life.
