There are ongoing challenges for housed IDU patients who require OPAT, as medical respite placement and home infusion are generally not options, and skilled nursing facility placement can be difficult. Careful review of substance abuse history; evaluation of psychosocial factors, such as housing status; mental health history; and outpatient support systems are needed.
Again, ID consultation is highly recommended to determine appropriate IV therapy, and if possible, early transition to oral antimicrobial therapy, as well as duration of treatment for specific illnesses on a case-by-case basis. Close follow-up is needed to ensure patient compliance with prescribed antimicrobial regimen, sometimes requiring weekly visits.
OPAT is effective for many patients, and it is optimal to utilize ID consultation to determine appropriate candidates – particularly among homeless and IDU patients. OPAT can be successful in a closely monitored medical respite setting for homeless patients with multiple comorbidities, with the help of a multidisciplinary team. Medical respite OPAT can decrease LOS in patients who would otherwise require long hospitalizations, resulting in overall cost savings.
