The time it takes to diagnose urinary tract infection is 48 – 72 hrs. Alfred 60 ( Alifax), an automated urine analyzer, was introduced into the Microbiology Unit of Ibn Sina Laboratory Department in November 2013. This study was done to compare the total time taken to release negative as well as positive cultures by Alfred 60 and the conventional culture, together with the manpower and resources saved by Alfred 60.
All urine specimens for culture received in the month of December 2014 are included in the study. They are processed by Alfred and conventional culture simultaneously. The time taken from receiving the specimens until the release of negatives by both Alfred 60 and conventional culture is calculated. The time taken for processing the positive cultures by Alfred 60 is calculated. Manpower and resource saving when using Alfred 60 compared to conventional culture is determined.
Results: Out of 1590 samples processed in the month of December 2014 by Alfred 60, 1261(80%) are negative and 319(20%) are positive at the end of 4 hrs. The positives are then processed by the conventional culture method and the a total of 212 plates both blood agar and cysteine lactose electrolyte deficient agar (CLED) are used in comparison to a total of 1060 plates used when conventional method is used for all specimens.The total time saved in inoculating 319 positive samples from Alfred as compared to inoculating all the 1590 samples is 21.2 hrs. The total time saved when negatives are released within 5 hrs by Alfred is 21 hrs. The total manpower saved was from 3 to 1 technician per day when using conventional culture compared to Alfred 60
By using Alfred 60, time, manpower and cost were significantly reduced with a significant impact on the rapid confirmation and exclusion of UTI with its effect on antimicrobial stewardship.
