Organisational quality and hospital pharmacists' roles of outpatient parenteral antimicrobial therapy (OPAT) in Belgian hospitals: a national survey.

Objectives: Implementation of outpatient parenteral antimicrobial therapy (OPAT), also known as intravenous (IV) antimicrobial treatment at home, has increased in recent years. Ensuring OPAT quality is crucial to achieve positive patient outcomes. However, data on the Belgian quality of OPAT organisation is lacking. We aimed to monitor the organisational quality of OPAT in Belgian hospitals and identify roles of hospital pharmacists involved in OPAT.

Methods: A cross-sectional study applying a web-based survey on OPAT quality was conducted from 2 to 29 April 2024. The survey assessed the presence of six core and five non-core structure indicators, and OPAT-related tasks of hospital pharmacists.

Results: Almost two-thirds (64%; 65/101) of Belgian hospitals answered the survey, with 77% of these hospitals providing OPAT, with an increase since 2023. All 11 structure indicators were present in 6% of hospitals, while 18% had all six core structure indicators.Three of the six core structure indicators were formally present in the majority of the hospitals: a policy on patient selection criteria (76%), a structured OPAT programme (70%), and a dedicated team (64%). In contrast, a system for fast communication between the patient and OPAT team members (50%), a mechanism for urgent clinical discussions (42%), and monitoring of quality indicators (28%) were not formally present in the majority of the hospitals. The primary tasks for hospital pharmacists included overseeing OPAT prescriptions and supplying antimicrobials and related materials.

Conclusion: While the adoption of OPAT is increasing among Belgian hospitals, significant opportunities remain for improving the quality of the OPAT organisation and expanding the OPAT-related tasks of Belgian hospital pharmacists.
