Abstract
Objective: To determine the trend of the prevalence of hospital associated infections (HAIs), and identify relevant factors of HAIs.
Subject and Method: Repeated point prevalence survey (PPS) on inpatients at the National Hospital of Pediatrics (NHP) in 2014. Hospital associated infections were determined by guideline of Ministry of Health. Data were analysed by SPSS 16.0 software.
Results: the overall prevalence of HAIS was 8.1%; these prevalence overall at the hospital, in ICU, in common wards were 11.0-28.4-6.1%; 7.3 - 18.3 t- 4.1%; 6.1-16.2-3.3% and 8.0-20.5-3.3% in each quarter consecutively. Most causes of HAIs were Acinetobacter spp (21.2%), Pseudomonas spp (20.5%), K. pneumoniae (14.4%), S. aureus (13.0%); less frequently met cause were Burkhoderia spp (1.4%) and Serratia spp (1.4%). The relevant factors were identified including neonatal ages (OR = 3.3, p <0.001); patients treated in other hospitals (OR = 2.3, p <0.001); treated in ICU (OR = 5.9, p <0.001); Patients with invasive procedures (OR = 2.5 to 5.3; p <0.001). Application of PPS helps to analyze the trends of HAIs and relevant associated factors. PPS might be widely applied in different hospitals. During the year of surveillance the prevalence of HAIs in NHP ranged from 6.1 to 11.0% (mean 8.1%). The major associated factors were neonatal group, treated in other hospital before NHP, suffer invasive procedures, etc...
Conclusion: Leading etiology which are gram-negative bacteria such as Acinetobacter spp, Pseudomonas spp, Klebsiella spp. S. aureus appear more common than before.
