Intravenous administration of quinupristin/dalfopristin outside the hospita
l setting has not been reported previously. We describe 37 outpatients rece
iving quinupristin/dalfopristin iv for infections including osteomyelitis,
bacteraemia, abscesses and cellulitis. The most frequent aetiological patho
gens found were Enterococcus faecium, Staphylococcus aureus and coagulase-n
egative staphylococci. Patients received an average of 9 days therapy as in
patients and 22 days as outpatients, Quinupristin/dalfopristin was administ
ered using various access devices, most commonly peripherally inserted cent
ral catheters and tunnelled central catheters. The bacteriological and clin
ical success rates were both 89.2%, Five patients were readmitted to hospit
al; one patient developed catheter-related bacteraemia. The most frequently
reported non-venous adverse events were nausea (18.9% of patients), myalgi
a (18.9%) and arthralgia (13.5%), Sixteen patients experienced venous acces
s-related events, most commonly infusion pain, oedema and phlebitis, In thi
s group of patients, for those who had difficult-to-treat infections, intra
