Assessment of the Quality Control of Urine and Wound Swab Samples Processing in Private Bacteriological Laboratories in Khartoum State

Abstract

The present study was carried out to evaluate the microbiological laboratories performance in private sectors in term of processing urine and swab samples for isolation, identification the bacteria and availability of requirements for susceptibility test. The study had done through two phases, before intervention phases where the current situation of these laboratories was reported, intervention course where the study group was instructed to select of media, proper system of identification and necessary items for susceptibility test. The intervention did not involve control group, the study group involved seven laboratories and control group involved four laboratories. The result of pre-intervention phase showed that both groups applied proper type of media in case of urine samples while in swab samples only 1(14%) and 1(25%) of study group and control group applied right media, entirely study population did not applied identification scheme. The study group and control group in pre- intervention phase did not had internal quality control for susceptibility test and applied rough method to measure the zone of inhibition, 2(29%) of study group and 1(25%) of control group did not had maccfarland reagent.The result after intervention phase of study group revealed (100%) response to primary protocol of urine and swab samples isolation and identification bacteria scheme while no change had occurred in control group. In susceptibility test the study group showed (88%) comply to test requirements where as no improvement had occurred in control group.
