The Epidemiology Prevalence Rate and Surveillance Performance of Hospital-acquired Infections in Medical Department at Nopparat Rajathanee Hospital
Keywords:Prevalence rate, Surveillance performance, Hospital-acquired infection
Background : Hospital-acquired infections (HAI) are significantly associated with morbidity and mortality. HAI can be preventable through the strict surveillance program, but the causes, prevalence of HAI should be firstly investigated in order to establish the surveillance program more efficiently. Objective: This research had twoobjectives : 1) to survey a prevalence of hospital-acquired infection, and 2) to examine the performance of the surveillance program using in the Medical Department at Nopparat Rajathanee Hospital.Methods : This study was a cross-sectional survey which collected data retrospectively from May 31 to June 30, 2018 in 8 wards under the Medical Department. Participants were patients who were admitted to the 8 wards more than 2 calendar days. Data were collected by infection control nurses and infection control ward nurses using the infection surveillance form 1 of Nopparat Rajathanee Hospital. The prevalence rate and the surveillance program were analyzed using descriptive statistics.Results : the prevalence rate was 5.3%, the top three units with highest prevalence rate of HAI were the female semi ICU (10.3%), the Medical Intensive Care Unit (MICU) (9.3%), and the Medical VIP ward (9.1%). The hospital-acquired pneumonia (HAP) was the most common nosocomial infection which accounted for 30.6%. The second and third common nosocomial infection were the catheter associated urinary tract infection (26.5%) and the urinary tract infection (16.3%). The surveillance program performance was 85.7%.Conclusion : The epidemiology of hospital-acquired infection in Medical Department at Nopparat Rajathanee Hospital. Classified by pathogens were hospital-acquired pneumonia (HAP) occurred with A.baumannii MDR (25%) E.coli and K. pneumonia (16.7%). The catheter associated urinary tract infection from E.faecalis, C.tropicalis (20%) and the urinary tract infection from E.faecium, E.coli (28.6%). The prevalence rate of HAI of the study (5.3%). The surveillance effectiveness of the study (85.7%) was hight for prevention and infection control.
