Abstract:

Background: There is increasing interest in outpatient parenteral antimicrobial treatment.

Objective: To evaluate the added value of consultation of an infectious diseases expert team (consisting of two internist-infectious diseases specialists and a microbiologist) for advice regarding type, administration route and duration of antibiotic treatment.

Setting: A retrospective case series was performed at the Haga Teaching Hospital, a 700-bed regional teaching hospital in The Hague, The Netherlands.

Methods: Complication rate and mortality was evaluated during 60 days of follow-up. Therapeutic rationality regarding outpatient parenteral antimicrobial treatment was determined by presenting randomly selected paper cases from the database to two independent infectious diseases specialists who were blinded to patient’s treatment and outcomes. The concordance between the two advices were analysed using Cohen’s kappa. For those with discordance, an infectious diseases expert team meeting was organized to reach consensus. The final recommendation was compared to the actual given antibiotic treatment. Main outcome measure Discrepancy between the infectious disease expert team recommendations upon type, administration route and duration of antibiotics and the real outpatient parenteral antimicrobial treatment practice.

Results: Out of 89 included cases, 50 were randomly selected for review by the infectious diseases specialists. The kappa statistic regarding antimicrobial policy was 0.581 (P < 0.001). In 78% (39/50 cases), they had complete agreement upon all aspects of antibiotic treatment. The remaining 11 cases were reviewed by the expert team. Comparing the consensus of 50 cases to actual practice, in 14(28%) cases there was a discrepancy suggesting potential room for improvement. Comparing the cases in whom an individual infectious diseases specialist was involved in real practice to those cases without, there was 18% versus 42% discrepancy with the recommendations of the expert team (OR 3.4; 95% CI: 0.9-12.5, P = 0.06). Complication rate was 19% including unplanned readmissions and side effects of antimicrobial agent or administration route. Conclusion: Though outpatient parenteral antimicrobial treatment policies in the Netherlands appear to be safe, consultation of an ID expert team, rather than an individual ID specialist, has the potential to optimize antimicrobial treatment in patients considered suitable for outpatient parenteral antimicrobial treatment.
