Impact of routine bedside infectious diseases service on clinical management and prognosis of patients with Candida fungemia - an example for Antifungal Stewardship at university level in Germany.

BACKGROUND

Candidemia is rare and has a high mortality rate. This study analyses the impact of bedside antifungal stewardship (AFS) on clinical management and prognosis of patients with candidemia at a university hospital in Germany.

METHODS

All patients with at least one positive blood culture with Candida species between 2014 and 2016 received bedside AFS with standardized recommendations. Medical records were retrospectively analyzed. Results from the intervention period from 2014-2016 (n=109), with focus on 2016 (n=39), were compared with those from the pre-intervention period in 2013 (n=30).

RESULTS

Bedside AFS was performed in 24/35 (69%) surviving patients in 2016 within the first 3 days after diagnosis of candidemia. All surviving patients (n=35) in 2016 received antifungal treatment compared with 24/28 (86%) in 2013 (p=0.0344). Follow-up blood cultures were performed in 25/35 (71%) in 2016 compared with 10/25 (40%) in 2013 (p=0.0046). Survival in the intervention compared with the pre-intervention group did not differ significantly (p=0.58) one year after the diagnosis of candidemia was made. However, patients with candidemia often have multiple serious comorbidities.

CONCLUSIONS

Individualized bedside AFS significantly improves adherence to recommendations for patients with Candida fungemia, especially guideline-oriented diagnostics and therapy. Improving the prognosis of patients with candidemia remains a huge challenge for AFS.
