  • Background: Asymptomatic bacteriuria is common, especially in chronically catheterized patients. Numerous studies have shown that providing evidence-based information improves medical trainees’ knowledge. Our objectives were to evaluate trainees’ current urine culture practices in catheterized patients; educate them about evidence-based indications; and assess the impact of this intervention.

    Methods: We conducted baseline and post education surveys of trainees at a 1541-bed academic medical center in New Haven, CT in January and March 2018. The survey included questions related to indications for ordering urine cultures in catheterized patients. Education about a recent institutional urine culture algorithm and guidelines was done via email and noon conferences. Scores were calculated on a scale of 0-12 with 1 point for each incorrect answer. Differences between means were evaluated by ANOVA and t-test in GraphPad Prism.

    Results: 163 of estimated 900 trainees (18%) responded to our baseline survey, with average scores improving with level of training (Table 1). 93 trainees responded to the post education survey, with improvement in scores across all levels of training (Table 1) and all questions (Figure 2). Trainees who reported that they did not receive any form of education scored significantly worse (4.68 vs 2.84, p<0.005, Figure 1), and the trainees who reported receiving multiple forms of education scored better than average (1.00 vs 2.84, p=0.06). There was no difference in score based on how the trainees were educated (Figure 1, p=0.98).

    Conclusion: Our data show that trainees at all levels improved their scores with education about culturing. The form of the education did not make a difference, indicating that it may be just as effective to send out electronic education as more time-intensive noon conferences. Future studies should focus on the sustainability of the impact of these educational interventions.
