Current perspectives on thehome and outpatient use of
parenteral antibiotics inCanada: An overview of the
conference
H Grant Stiver MD FRCPC
Since the initial clinical trial demonstrating the safety, effi-
cacy and cost advantages of outpatient intravenous anti-
biotic therapy (OPAT) in the mid-1970s, outpatient parenteral
antibiotic therapy has become a major therapeutic program in
most Canadian hospitals (1). In the mid-1990s, the value of
this avenue of treatment had become even more apparent as
greater cutbacks in the availability of hospital care take place.
Because many patients requiring three to four weeks of anti-
biotic therapy now routinely receive two-thirds of the course
at home or at an infusion clinic, the average cost ratio compar-
ing OPAT with hospital-based therapy is 12 cents on the dol-
lar (2).
The degree of patient and patient’s family satisfaction has
been high, and newer infusion devices (eg, peripherally in-
serted catheters) and computerized ambulatory drug delivery
pumps allow almost any type of antibiotic regimen to be given
with a minimum of intervention required from the patient (3).
OPAT has always been a team concept comprising usually,
but not necessarily, infectious disease physicians, clinical
pharmacists and nursing specialists. The OPAT conference
held in Toronto, April 17 to 19, 1998, brought together experi-
enced health care personnel from across Canada to compare
different provincial OPAT programs regarding methods of
funding, logistical approaches, pharmacological and thera-
peutic profiles, clinical experiences, and future plans. In addi-
tion, a major focus of the conference was to formulate clinical
care plans for the antibiotic management of endocarditis, sep-
tic arthritis and osteomyelitis, diabetic foot infection, respira-
tory tract infection, cellulitis and infection in neutropenic
patients, and to provide definitions of the role of OPAT in
these infections. It is hoped that physicians and other OPAT
healthcare personnel in the community will be able to use
these care plans, and OPAT therapeutic and care overviews as
guidelines for OPAT in their own practice settings.
