How to Join

Members of an ISAC Member Society are eligible to join any of our Working Groups. If you are a member and would like to join this group, please contact the Chairperson and Secretary (if applicable).

Aims and Objectives

Outpatient parenteral antibiotic therapy (OPAT) is a system of care which facilitates early hospital discharge or even completely prevents admission. It began in 1974 in paediatric patients in the US. Since then the UK, Australia, New Zealand and Canada as well as countries in Europe, South America and Asia have institutionalized this mode of care. There are a variety of clinical and funding models each for the same endpoint. It is proven to be safe and cost beneficial. OPAT improves the quality of patients’ lives by providing treatment in a preferred setting and facilitates an earlier return to work or school. It may also lower patients' risk of acquiring healthcare-associated infections. More recently it has been seen as a tool for antimicrobial stewardship.

Aims of the Working Group -

  • Foster the international exchange of ideas with regards to service models, benchmarking and multicenter research into all aspects of OPAT
  • Support the implementation of OPAT in countries seeking its establishment
  • Encourage collaborative research on OPAT especially clinical trials

Our Work Plan - 

  • Write to IDSA for focal points in US
  • A Point prevalence survey on activity worldwide
  • Symposia within conferences
  • Dedicated conference
  • Journal supplements
  • Multicenter trials
  • Engaging industry
  • Training products for individuals
