| Summary: | From January 1, 1996 to December 31, 1996, 343 patients received outpatient intravenous antibiotic therapy at Charles
LeMoyne Hospital, a 436-bed, acute care hospital in Greenfield Park, south of Montréal, Québec. The infectious diseases
department saved 2660 bed-days using outpatient therapy. The mean duration of outpatient therapy was 7.76 days;
81.6% of patients were admitted to the program directly from the emergency room, or outpatient hospital clinics or private
offices in the community. Hospitalized patients constituted only 18.4% of admissions to the outpatient intravenous
antibiotic therapy program. Forty per cent of the surgical/medical staff participated in the program and they were able to
generate a significant impact by diverting patients to outpatient therapy. Two types of patients can benefit from an outpatient
intravenous antibiotic therapy program. One group of patients needs empirical short term therapy and can be
switched to oral sequential therapy after two to five days of outpatient intravenous antibiotic therapy. A second group of
patients needs specific long term therapy for the full duration of the antibiotic therapy. Empirical short term therapy can
be managed by emergency department or hospital-based primary physicians, or medical/surgical specialists. Specific
long term therapy can be managed by microbiology/infectious disease specialists or medical/surgical specialists. Hospitals
that want to relieve pressure on emergency rooms and hospital bed demands should create facilities for both types of
patients. Cefazolin and gentamicine/tobramycine were the most commonly used antibiotics in empirical short term therapy
and in terms of number of patients treated. Ceftriaxone and vancomycin were most commonly used for long term
therapy. The Drug acquisition antibiotic cost was $73,117 but constituted only 20% of the total outpatient intravenous
antibiotic therapy cost. The per diem ambulatory cost was $140/patient/day.
