Objectives: Patients receiving outpatient parenteral antimicrobial therapy (OPAT) may require emergency department (ED) visits to manage complications. This study's purpose was to identify risk factors for ED visits during OPAT and risk factors for hospitalization among patients with ED visits.Methods: All OPAT courses initiated between 1 January 2013 and 1 January 2017 at Cleveland Clinic were identified. The first OPAT course per patient was included. For these, ED visits within 30 days were identified. Reasons and risk factors for these visits were sought, as were risk factors for hospitalization among patients visiting the ED.Results: Among 8263 patients on OPAT, 381 (4.6%) had at least one ED visit, an additional 1133 (14%) were hospitalized and an additional 50 (0.6%) died, within 30 days. One hundred and ninety-three ED visits (51%) were OPAT related. In a multivariable subdistribution proportional hazards competing risks regression model, prior ED visit (preceding year) was most strongly associated with ED visits (HR 2.29, 95% CI 1.76-2.98, P = 8.1 × 10-10). Eighty-five visits (22%) led to hospitalization. Compared with non-OPAT-related reasons, visits for vascular access complications were associated with lower odds of hospitalization (OR 0.36, 95% CI 0.14-0.83, P = 0.022) and visits for worsening infection with higher odds (OR 18.95, 95% CI 5.50-79.85, P = 1.2 × 10-7).Conclusions: Compared with patients without, patients with prior ED visit have a 2.3-fold higher hazard of an ED visit within 30 days of OPAT initiation. Visits for worsening infection are much more likely to result in hospitalization than those for vascular access complications. [ABSTRACT FROM AUTHOR]

Objectives: The need for indwelling vascular access for outpatient parenteral antimicrobial therapy (OPAT) places patients at risk of vascular access complications. The purpose of this study was to describe vascular access complications during OPAT at home, and identify factors associated with their occurrence. Methods: All OPAT courses carried out at home for patients at Cleveland Clinic in 2013 were identified from the institution's OPAT registry. The first OPAT course per patient was included. Vascular access complications that occurred during the treatment course were abstracted from the electronic medical record. Only complications that triggered a clinical intervention were included. Results: The 1461 included OPAT courses encompassed 33579 OPAT days of treatment. One-hundred-and-fortyfour vascular access complications occurred in 131 OPATcourses (9%of OPATcourses, 4.29 complications per 1000 OPAT days). The most common complication was occlusion (53% of all complications). Hickman catheters [incidence rate ratio (IRR) 0.20, 95% CI 0.03-0.63] and indwelling ports (IRR 0.25, 95% CI 0.04-0.78) were associated with lower complication rates than peripherally inserted central catheters, as was increasing age (IRR 0.99, 95%CI 0.98-1.00). Log OPATduration (IRR 1.60, 95%CI 1.28-2.03), female sex (IRR 1.62, 95%CI 1.16-2.28) and injection drug use (IRR 3.32, 1.16-7.46) were associated with increased risk of vascular access complications. Conclusions: Nine percent of OPATcourses at homehave at least one vascular access complication requiring clinical intervention. Longer OPAT duration, younger age, female sex and injection drug use are associated with increased risk of vascular access complications. [ABSTRACT FROM AUTHOR]

Intravenous administration of quinupristin/dalfopristin outside the hospital setting has not been reported previously. We describe 37 outpatients receiving quinupristin/dalfopristin iv for infections including osteomyelitis, bacteraemia, abscesses and cellulitis. The most frequent aetiological pathogens found were Enterococcus faecium, Staphylococcus aureus and coagulase-negative staphylococci. Patients received an average of 9 days therapy as inpatients and 22 days as outpatients. Quinupristin/dalfopristin was administered using various access devices, most commonly peripherally inserted central catheters and tunnelled central catheters. The bacteriological and clinical success rates were both 89.2%. Five patients were readmitted to hospital; one patient developed catheter-related bacteraemia. The most frequently reported non-venous adverse events were nausea (18.9% of patients), myalgia (18.9%) and arthralgia (13.5%). Sixteen patients experienced venous access-related events, most commonly infusion pain, oedema and phlebitis. In this group of patients, for those who had difficult-to-treat infections, intravenous quinupristin/dalfopristin therapy was generally effective and safe outside the hospital setting.
