Urine culture & sensitivity (C&S) is an important test to support the diagnosis of urinary tract infection. However, it is easily contaminated during handling the specimen. A contaminated urine culture is defined as the presence of more than 1 isolation at greater than or equal to 100 000 CFU/mL. 40% is the standard contamination rate for this study. The aim of this study is to reduce the contamination rate of urine culture among infants in the health clinics under Kota Bharu district, to identify the contributing factors and to provide strategic intervention to overcome the problem.
A cross-sectional study comparing pre and post interventions was conducted in 2019. Data were collected from the questionnaires, laboratory information system (LIS) named Sistem Informasi Makmal Kesihatan Awam (SIMKA) and urine C&S lab form. A total of 40 validated questionnaires were given to the clinic staffs randomly at 10 health clinics. Data were analysed and intervention were carried out to tackle the problem. CME on proper procedure in urine C&S and the practical session on Bladder Stimulation Technique as alternative way in clean catch urine method were done at selected health clinic. CDs, posters, and flyers on standard procedure of urine C&S also had been distributed to all health clinic in Kelantan.
Post intervention, the urine contamination rate slightly reduced from 59.6% to 52.5% which is still higher than the standard (<40%). In general, the percentage of the good practice increasing for urine collection, storage and transportation. The level of knowledge for category ‘poor’ was reducing from 5% to zero. Clean catch urine as the preference method for the collection of urine also increasing from 17.5% to 32.5%.
Continuous monitoring of urine culture contamination and sustaining the remedial measures are very important to control the problem. There is room for improvement to reduce the contamination rate of urine culture among infant for sample received in Kota Bharu Public Health Laboratory.
