Types of pre-surgical complication.

Objectives
To determine the clinical, laboratory, and hospital factors associated with preoperative complications in older adults with hip fractures.
Methodology
Analytical observational retrospective cohort study, whose population was older adults with a diagnosis of hip fracture treated in a hospital in northern Peru, during 2017–2019.
Results
432 patients with a median age of 83 years (RIC: 77–88) were evaluated, with the female gender being the most prevalent (60.9%). The most common comorbidities included cardiovascular disease (68%) and diabetes (17.6%), and multimorbidity was observed in 47.2% of cases. The median number of geriatric syndromes was 2 (RIC: 1–5). The overall mortality rate was 3.2% (1.7–5.3). Analysis with the Poisson regression model found a significant association with MRC scale 3–5 degree (RR = 1.60), glucose on admission (RR = 1.01), and minimally significantly female sex (RR = 2.41).
Conclusions
The most commonly observed complications were infectious in nature, including pneumonia, sepsis, and urinary tract infections. The MRC scale from 3 to 5 degrees increases the risk of developing a preoperative complication; the glucose levels upon admission show a clinically irrelevant association; and in females, there is a minimally significant association in older adults with hip fractures.
