SURVEYING THE RATE OF CONFIDENTIAL BLOOD TRANSPORTATION AND SOLUTIONS TO ENHANCE THE QUALITY OF BLOOD TREATMENT AT THE CENTER FOR TROPICAL DISEASES OF NGHE AN FRIENDSHIP GENERAL HOSPITAL

Abstract

Background: Contamination in blood cultures is a challenge to identify causative agents of infections. Which may complicate clinical indications, or prolong the time of diagnosis, and affect treatment outcomes.
Objectives: To determine the rate of contamination in blood cultures, and implement some interventions to improve the quality of blood cultures, to reduce proportion of blood cultures contamination below 3%.
Subjects and methodology: All Blood cultures of patients who were treated at the Center for Tropical Diseases, Nghe An Friendship General Hospital from October 2020 to March 2021.
Cross - sectional descriptive study.

Results: There were 1756 cultured blood samples; from October to December 2020: 894 samples, from March 1, 2021: 862 samples. Rate of positive culture was 25.7%, of which true positive 12.9%, contamination: 12.8%, true negative: 74.3%. Contamination before training was 16.1%, and decreased to 9.4%after training. Coagulase - negative Staphylococci bacteria caused 63.2% contamination,
accounted higher proportion than Gram - positive bacilli as 21.2%.
Recommendation: We could not eliminate blood cultures contamination, but we could reduce the amount of contamination. Training in awareness and practice greatly reduces the prevalence of blood cultures contamination.
