Point-prevalence of Hospital-Acquired Infections at Vietnamese Urban Hospital

Abstract

Background: This study aimed to evaluate the prevalence of hospital-acquired infections among inpatients at a public hospital in Vietnam, and analyze the factors associated with this condition. Methods: Two cross-sectional surveys were conducted in 2018 and 2019 on 1463 patients at Thanh Nhan Hospital, Hanoi, Vietnam. The point-prevalence of hospital-acquired infections was assessed. A multivariable logistic regression model was applied to identify factors related to hospital-acquired infections. Results: Among 1463 patients, 88 patients had hospital-acquired infections (6.0%), with mainly surgical site infections (37.5%), upper respiratory tract infection (23.9%) and pneumonia (13.6%). Most common bacteria were Pseudomonas aeruginosa (27.8%), followed by Klebsiella pneumoniae (13.9%) and Acinetobacter spp. (8.3%). Being females (OR=2.01, 95% CI=1.17-3.45), having heart-related diseases (OR=3.60, 95% CI=1.96-6.63), having surgery (OR=7.82, 95% CI=3.80-16.09) and higher days from hospitalization to HAI examination date (OR=1.07, 95% CI=1.04-1.10) were factors associated with a higher likelihood of suffering from HAIs. Conclusion: Future interventions should focus on the prevention and control of hospital-acquired infections in patients undergoing surgery and in patients with heart-related diseases and patients with the prolonged hospital stay.
