High prevalence of bacteriuria in pregnancy and its screening methods in north India.

The study aims at finding out the prevalence of bacteruria in pregnancy in an urban setting and ascertaining methods to screen them in primary care clinics. A total of 1 61 pregnant ladies visiting a primary care clinic were screened for bacteriuria based on the symptomatology. Urine culture was done to know the prevalence of bacteriuria. Sensitivities and specificities were calculated for each symptom and risk assessment. A score card was developed based on combination of positive risk assessment and constellation of symptoms. Prevalence of symptomatic and asymptomatic bacteriuria was found to be 19.87% and 4.34% respectively. Prevalence of bacteriuria was significantly high among those who had intercourse more frequently and those with less water intake. Those with a score of more than or equal to 4, as per score card were 60% more likely to suffer from bacteriuria. When combined with microscopic examination for leucocytes on positively screened, the positive predictive value was found to be 89%. It is concluded that prevalence of symptomatic bacteriuria is common among pregnant women. Syndromic management of cases on the basis of score card is helpful in resource constraint areas. This may be combined with microscopic examination of urine to entail rational use of antibiotics.
