Patients were divided into two groups: perioperative pneumonia (POP) group and non-perioperative pneumonia (non-POP) group.Logistic regression models were used to identify independent risk factors.Statistical significance was set at 5% (p< 0.05).Results: The incidence of perioperative pneumonia (POP) in patients 80 years and older was 11.
3% (33/293).Male patients had a higher incidence of POP (20/96 cases, 20.83%) compared to females (13/197, 6.6%)(P< 0.001).
Higher neutrophilic granulocyte percentages (78.148%± 9.162% in POP vs 81.959%± 6.142% in Non-POP, P=0.
033) and lower albumin levels (χ2=2.25, P=0.039) were observed in the POP group at baseline.After multivariate logistic regression, we observed that males (OR=3.402, P=0.
048), lower albumin levels (OR=10.16, P=0.001) and PaO2 levels strikketøy oppbevaring (OR=2.916, P=0.007) were independent risk factors for POP.
Conclusion: Low albumin and oxygen levels and the male gender were risk factors for perioperative pneumonia in geriatric hip fracture patients.Keywords: hip fracture, pneumonia, elderly, perioperative, male, hypoalbuminemia, arterial blood gas analysis.
