RT Journal Article SR Electronic T1 Antibiotic resistance of uropathogenic Escherichia coli and ESBL prevalence in general practice patients over 10 years JF British Journal of General Practice JO Br J Gen Pract FD British Journal of General Practice SP bjgp20X711533 DO 10.3399/bjgp20X711533 VO 70 IS suppl 1 A1 Antoinette van Driel YR 2020 UL http://bjgp.org/content/70/suppl_1/bjgp20X711533.abstract AB Background Bacterial susceptibility to antibiotics changes over time. Knowledge of the susceptibility is important for antibiotic treatment guidelines in general practices.Aim To determine the antibiotic-susceptibility of E. coli from uncomplicated UTI among women in general practices in the Netherlands and to compare the results with those collected in 2004 and 2009.Method Urine samples were collected from women with symptoms of uncomplicated UTI, in 30 sentinel GP practices of the Nivel Primary Care database. Patient characteristics, E. coli susceptibility and ESBL prevalence were analysed.Results In total, 689 samples were collected. E. coli was the most isolated uropathogen (83%). Antibiotic susceptibility was stable over time except for ciprofloxacin (96%, 97% and 94% in 2004, 2009 and 2014, respectively; P<0.05). The susceptibility to co-amoxiclav was 88%, 87% and 92% in 2004, 2009 and 2014, respectively. The prevalence of ESBL producing E. coli increased from 0.1% in 2004, to 2.2% in 2014 (P<0.05). Susceptibility for co-trimoxazole was the highest in the West (88%) and the lowest in the North (72%, P = 0.021). Ciprofloxacin susceptibility was related to antibiotic use in the past 3 months (97% no use versus 90% use, P = 0.002) and those aged >70 years (P = 0.005). In 2014, prescription of fosfomycin increased compared to 2009 (14.3% versus 5.6%) at the expense of co-amoxiclav, co-trimoxazole and ciprofloxacin (P<0.05).Conclusion The antibiotic susceptibility percentages to the agents tested were stable over the 10-year period, except for ciprofloxacin as was the prevalence of ESBL producing E. coli. Surveillance with regular intervals is warranted.
