Survey of delivery of parenteral antimicrobials in non-inpatient settings across Europe.

Delivery of parenteral antimicrobials in non-inpatient settings (DPANS) may be through a dedicated outpatient parenteral antimicrobial therapy (OPAT) service, co-ordinated by hospital- or community-based specialised teams, or via an infusion service involving community-based health professionals (nurses, general practitioners) without centralised hospital oversight, or through ad hoc arrangements. DPANS varies among countries. Our objective was to describe how DPANS is organised at a national level in European countries. A survey (65-item self-administered questionnaire) was conducted from February-June 2019 among infection specialists in 34 European countries on behalf of the ESCMID Study Group for Antimicrobial Stewardship (ESGAP) and the British Society for Antimicrobial Chemotherapy (BSAC) OPAT initiative. Most countries (28/34; 82.4%) participated in the survey. DPANS was available in almost all (27/28; 96.4%) responding countries. DPANS was predominantly provided either via specialised OPAT services (17/28; 60.7%) or via infusion services (16/28; 57.1%), with 11 countries (39.3%) providing both services. A formal OPAT team structure with specifically trained staff was reported in only six countries (6/17; 35.3%). Some countries (4/28; 14.3%) had no structured services but practiced DPANS via ad hoc arrangements. The costs of all stages of the process were covered for patients managed by specialised OPAT/infusion services, either completely, partially or for specific patient groups in the majority (20/28; 71.4%) of countries. The main barriers to implement OPAT/infusion services were lack of organisational structure or guidelines. In conclusion, DPANS with respect to availability and organisation is highly heterogeneous in Europe. National/European guidelines may help improve and standardise DPANS.
