Abstract

Background: Surgical management of congenital heart disease (CHD) has increased worldwide, but healthcare-associated infections (HAI) can impede these efforts. This study analysed the incidence of HAI, the impact of preventive interventions, and microbiological profiles in a paediatric cardiovascular surgery program.

Methods: Cohort study including children under 12 years of age with CHD who underwent cardiovascular surgery between 2010-2021 in Medellín, Colombia (a middle-income setting). Data were collected from medical and laboratory records and infection control program databases. Impact of various preventive interventions was assessed using a Poisson model. A p-value less than 0.05 was considered statistically significant.

Results: 2512 surgeries were analysed. Incidence of surgical site infection (SSI) was 5.9%, followed by central line-associated bloodstream infection (CLABSI; 4.7%), catheter-associated urinary tract infection (CAUTI; 2.2%) and ventilator-associated pneumonia (VAP; 1.4%). Most of the strategies focused on preventing SSI, resulting in a reduction from 9.5% in 2010 to 3.0% in 2021 (p=0.030). Antibiotic prophylaxis based on patient weight and continuous infusion had an impact on reducing SSI (RR:0.56; 95%CI:0.32-0.99). Vacuum-assisted closure (VAC) in clean wounds reduced 100% infections. No significant risk reduction was observed for other HAI with the implemented interventions.

Conclusion: Preventive strategies effectively reduced SSI but no other infections, emphasizing the need for targeted approaches to address a broader spectrum of HAI successfully.
