From sea to shining IV: the current state of OPAT in the United States.

First described in the United States, outpatient parenteral antibiotic therapy (OPAT) has become an indispensable part of treating serious infections. The proportion of infectious disease (ID) physicians utilizing a formal OPAT program has increased in recent years, but remains a minority. In addition, many ID physicians have indicated that OPAT programs have inadequate financial and administrative support. Given the medical complexity of patients receiving OPAT, as well as the challenges of communicating with OPAT providers across health care facilities and systems, OPAT programs ideally should involve a multidisciplinary team. The majority of patients in the United States receive OPAT either at home with assistance from home infusion companies and visiting nurses or at a skilled nursing facility (SNF), though the latter has been associated with lower rates of patient satisfaction. Current and future opportunities and challenges for OPAT programs include providing OPAT services for people who inject drugs (PWID) and incorporating the increasing use of oral antibiotics for infections historically treated with parenteral therapy. In this review, we will discuss the current practice patterns and patient experiences with OPAT in the United States, as well as identify future challenges and opportunities for OPAT programs.
