1297Evaluation of Outpatient Parenteral Antimicrobial Therapy (OPAT) at a Veterans Affairs (VA) Hospital

Abstract Background Dalbavancin, a lipoglycopeptide with prolonged half-life targeting Gram-positive organisms, is approved for treatment of acute bacterial skin and soft tissue infection. It reduces hospital duration in patients with barriers to short-term rehabilitation or outpatient parenteral antimicrobial therapy (OPAT). Increasing evidence supports the off-label use of dalbavancin to treat other types of infection. We conducted a quality improvement study to evaluate outcomes following dalbavancin administration. Methods We performed a cohort study of recipients of ≥1 dose of dalbavancin from 1/31/2016-1/31/2021 at the Veterans Affairs Connecticut Healthcare System. Demographic, comorbidity, microbiological, antibiotic duration prior to dalbavancin, indication for dalbavancin, and type of infection data were collected. Outcomes included 1) lab abnormalities: hepatotoxicity within 2 weeks of dalbavancin; 2) clinical cure: resolution of symptoms of infection within 90 days; 3) all-cause readmission within 90 days; and 4) all-cause mortality within 90 days. Results 42 patients met criteria. Median age was 69 years (range, 32-91), 100% were male, 55% (n=23) had diabetes, 31% (n=13) had liver disease, 36% (n=15) had other immunosuppressive conditions, and 12% (n=5) had substance use disorder (SUD). All received their first dose as inpatients. Median hospital duration was 8 days (range, 1-32). 4 (10%) required critical care. Median antibiotic duration prior to dalbavancin was 7 days (range, 1-42). Indications included ineligibility for OPAT (n=21, 50%), pharmacologic reasons (n=10, 24%), ineligibility for peripherally inserted central catheter (n=6, 14%), or SUD (n=5, 12%). Common microorganisms were Staphylococcus spp. (n=22, 52%), polymicrobial (n=13, 31%), and Corynebacterium spp. (n=10, 24%). 93% (n=39) had clinical cure of infection; readmissions and mortality were rare (Table 1). Conclusion Dalbavancin was associated with clinical cure for diverse infections with low rates of adverse events, readmission and mortality in patients ineligible for traditional OPAT. Although confirmatory data are needed from larger studies, dalbavancin appears to be a versatile therapeutic agent for Gram-positive infections. Disclosures All Authors: No reported disclosures

Abstract Background Outpatient parenteral antimicrobial therapy (OPAT) allows safe delivery of IV antibiotics in ambulatory settings to facilitate hospital discharge. Within the Veterans Affairs (VA) system, OPAT programs face the unique challenges of large geographic coverage areas and referrals for veterans from non-VA hospitals. Methods Patients enrolled in the VA North Texas Health Care System OPAT program during fiscal years 2016 to 2018 had data collected on demographics, comorbidities, OPAT indications, antimicrobials used, pharmacist interventions, and complications during therapy. Data were collected from retrospective chart review as a quality improvement project. All enrolled OPAT patients required either an inpatient infectious disease (ID) consult or, for patients from non-VA facilities, required medical records review and telephone consultation with approval by a VA ID clinician. A third-party infusion company provided all medications and line care. Weekly laboratory monitoring and follow-up telephone visits were conducted by ID-trained pharmacists. Results During the evaluation period, 485 unique OPAT encounters (425 patients) were completed, with 164 patients (33%) directly admitted to OPAT upon referral from non-VA hospitals. Most common OPAT indications were osteomyelitis/diabetic foot infections (40.4%), bacteremia (17.3%), prosthetic joint infections/septic arthritis (12.4%), and urinary/intrabdominal infections (11.7%). Following standardization of pharmacist documentation, the volume and consistency of documented notes and interventions increased. Readmission rates while on therapy were similar, ranging from 13.4% to 13.7% each year. Patient demographics and OPAT outcomes demonstrated steady growth in the program (Table 1) with low rates of complications on therapy (Table 2). The program served patients in 35 counties and 158 zip codes across a broad geographic region in North Texas and southern Oklahoma (Figure 1). The most commonly used antibiotics are shown in Figure 2. Conclusion Our program has demonstrated the ability to safely and effectively provide OPAT across a large geographic region from a central location. ID-trained clinical pharmacists are critical to the care coordination and safety monitoring of OPAT in this unique setting. Disclosures All authors: No reported disclosures.

Access Complications

Abstract Background Outpatient parenteral antimicrobial therapy (OPAT) carries risk of vascular access complications, antimicrobial adverse effects, and worsening of infection. Both OPAT-related and unrelated events may lead to emergency department (ED) visits. The purpose of this study was to describe adverse events that result in ED visits and risk factors associated with ED visits during OPAT. Methods OPAT courses between January 1, 2013 and December 31, 2016 at Cleveland Clinic were identified from the institution’s OPAT registry. ED visits within 30 days of OPAT initiation were reviewed. Reasons and potential risk factors for ED visits were sought in the medical record. Results Among 11,440 OPAT courses during the study period, 603 (5%) were associated with 1 or more ED visits within 30 days of OPAT initiation. Mean patient age was 58 years and 57% were males. 379 ED visits (49%) were OPAT-related; the most common visit reason was vascular access complication, which occurred in 211 (56%) of OPAT-related ED visits. The most common vascular access complications were occlusion and dislodgement, which occurred in 99 and 34 patients (47% and 16% of vascular access complications, respectively). In a multivariable logistic regression model, at least one prior ED visit in the preceding year (prior ED visit) was most strongly associated with one or more ED visits during an OPAT course (OR 2.96, 95% CI 2.38 – 3.71, p-value < 0.001). Other significant factors were younger age (p 0.01), female sex (p 0.01), home county residence (P < 0.001), and having a PICC (p 0.05). 549 ED visits (71%) resulted in discharge from the ED within 24 hours, 18 (2%) left against medical advice, 46 (6%) were observed up to 24 hours, and 150 ED visits (20%) led to hospital admission. Prior ED visit was not associated with hospital admission among patients who visited the ED during OPAT. Conclusion OPAT-related ED visits are most often due to vascular access complications, especially line occlusions. Patients with a prior ED visit in the preceding year have a 3-fold higher odds of at least one ED visit during OPAT compared with patients without a prior ED visit. A strategy of managing occlusions at home and a focus on patients with prior ED visits could potentially prevent a substantial proportion of OPAT-related ED visits.

Hospital Days

Abstract Background Uninsured patients requiring long-term intravenous (IV) antimicrobials do not have access to outpatient parenteral antimicrobial therapy (OPAT) and often remain hospitalized for the duration of their treatment, transition to inferior oral antimicrobials, or leave against medical advice. A hospital-supported self-administered OPAT (S-OPAT) program was piloted in uninsured patients to decrease hospital length of stay and improve access to care. Methods Uninsured adult patients requiring IV antimicrobials were enrolled in an S-OPAT pilot study from July 2019 to April 2020. Patients with drug use history or documented non-adherence were excluded. S-OPAT patients attended weekly clinic visits for blood draws, dressing changes, and medication supply. The measured outcomes were hospital days saved, and potential income generated by earlier discharges. The latter was calculated by multiplying the number of hospital days saved by the daily charge for a hospital bed to insured patients. Results Seventeen patients were enrolled in S-OPAT, 14 (82%) were males, 8 (47%) were black, and the mean age was 39 years. The most common indication for OPAT was bone and joint infections in 12 (71%), and most commonly used antibiotic was ceftriaxone in 12 (71%) patients (Table). Early discontinuation occurred in 3 (17%) patients due to clinic visit non-adherence resulted in 2 (12%) and adverse drug events in 1 (6%). Only one (6%) patient had unplanned hospital readmission during OPAT. Transition to S-OPAT resulted in 533 hospital days avoided, and a net saving of approximately $900,000. Conclusion S-OPAT model is safe and can enhance care for uninsured patients while optimizing health-system resources. Table Disclosures All Authors: No reported disclosures
