• W2981570046 abstract "Abstract Background Blood cultures are the gold standard in the identification of laboratory confirmed bloodstream infections (LCBI) but contamination can lead to unnecessary interventions. This study sought to assess the number of unwarranted admissions in patients with contaminated blood cultures post-discharge and at low risk for LCBI before and after the implementation of a multidisciplinary emergency department (ED) blood culture follow-up program. Methods This was a two-phase retrospective cohort study at a tertiary care, 1,550-bed, academic hospital and level I trauma center in southeast Florida. Phase 1 assessed interventions made on patients 18 years of age or older discharged from the ED or a hospital observation unit with a positive blood culture result post-discharge from March 2018 to July 2018. Phase 2 assessed interventions made from December 2018 to March 2019 post-implementation of the multidisciplinary follow-up program. The criteria for low risk of LCBI were lack of risk factors for infection and < 2 positive blood cultures with a commensal bacteria with no symptoms of fever or hypotension on the date of specimen collection and 3 days before or after such date. Results Among patients at low risk for LCBI (46% of 24 patients in phase 1 vs. 59% of 22 patients in phase 2), unwarranted admissions due to contaminated blood cultures occurred in 27.3% of patients in phase 1 vs. 0% of patients in phase 2 (P = 0.08). Phase 1 represented a period in which systematic reporting and evaluation of positive results and patient follow-up were not in place. Phase 2 consisted of daily pharmacist-led blood culture reviews with callback nurse follow-up and therapeutic care plan development with ED physicians. The number of contaminant isolates was relatively high (Figures 1 and 2). Pharmacist-led interventions were diverse (Figure 3). The program led to an estimated total cost avoidance of $16,410.80 in a median of 4.5 months due to unnecessary admissions. Conclusion Implementation of a multidisciplinary ED post-discharge blood culture follow-up program can be an effective strategy in improving patient care and avoiding unnecessary antibiotic therapy. Further interventions aimed at reducing blood culture contamination could have a direct impact on improving ED antimicrobial stewardship. Disclosures All authors: No reported disclosures." @default.
