Outpatient Parenteral Antimicrobial Therapy

Background: Despite the numerous benefits of outpatient parenteral antimicrobial therapy (OPAT), appreciable risks of drug-related problems (DRPs) exist. No studies to date comprehensively assess DRPs in this population. Objectives: Objectives of this study were to (1) characterize the frequency and types of DRPs experienced by patients discharged on OPAT and (2) determine the fraction of adverse drug reactions (ADRs) resulting in hospital readmission or emergency department (ED) presentation and changes in therapy. Methods: This was a retrospective chart analysis evaluating consecutive adult patients discharged on OPAT between May 2015 and October 2015. Patients were assessed for the presence of DRPs until the cessation of antimicrobial treatment, including oral step-down therapy. The outcome of each ADR was recorded, including those resulting in hospital readmissions, presentation to the ED, or changes in antimicrobials. Results: Among 144 patients discharged on OPAT, 199 DRPs occurred in 91 (63.2%) patients. Harm and potential impaired efficacy occurred in 76.9% and 23.1%, respectively. The ADRs comprised 59% of DRPs, occurring in 44.4% of patients. The second most common DRP type was drug interactions (DIs), accounting for 22.6% of DRPs. Rifampin, fluoroquinolones, and daptomycin had the highest frequencies of preventable DRPs in the form of DIs, whereas cephalosporins had the fewest DRPs. Approximately 26% of ADRs caused changes in therapy and 9% resulted in hospital readmission or ED utilization. Conclusion: DRPs with the potential to cause patient harm or impair treatment efficacy often occur with OPAT, most commonly ADRs and DIs. Enhanced monitoring and transitions of care management may reduce the incidence of these DRPs.

The Impact

Abstract Background Our large academic medical center initiated both an Outpatient Parenteral Antimicrobial Therapy (OPAT) program supported by an infectious disease trained pharmacist, along with an Orthopedic Infectious Disease (OID) consult service to assist in caring for these specialized populations. We measured the impact of these services. Methods Patients discharged on parenteral antimicrobial therapy were divided into two groups. The pre-OPAT cohort included all patient receiving OPAT from 4/1/18 - 10/31/18; the post-OPAT cohort included all patients who received OPAT from 4/1/19 - 10/31/19 with OPAT consult (Fig 1). The OID consult service began in September 2018 prior to initiation of the OPAT program. The primary outcome was 30-day hospital readmission. Secondary outcomes included: length of stay (LOS), 90-day readmission, clinical outcomes, and identification of predictors of hospital readmission. Clinical outcomes included: time from final OR visit to discharge for OID patients and optimal treatment (cefazolin, oxacillin, or nafcillin) for MSSA. Results Introduction of these programs was associated with a reduction in all-cause 30-day readmission from 39.3% to 22.9%, and a reduction in 30-day readmission for patients on-treatment from 24.6% to 15.6% (p< 0.01 for both). No difference was seen in hospital LOS (8 days in each cohort). In a subgroup analysis (Fig 2), OID patients in the post-OPAT cohort saw a median reduction of 2 days (7 days to 5 days, p=0.002) in time from final OR visit to discharge. Use of optimal treatments for MSSA increased in the post-OPAT cohort compared to pre-OPAT (65.2% to 80.9%; p=0.06). The 90-day hospital readmission rate were higher in the post-OPAT cohort among patients who lived in metro-area zip codes (p=0.03). Having an established primary care physician was associated with lower 90-day hospital readmission in both the pre-and post-OPAT cohorts (p=0.05 and 0.01, respectively). Conclusion Thirty-day readmission rates among patients discharged on OPAT significantly lowered following initiation of a combination of both a pharmacist-led OPAT program and OID consult service. OPAT and OID programs accrue additional efficiencies and clinical benefits to both patients and hospitals, which can be further evaluated and used to justify such service additions.

Abstract Background Transitions of care from hospitals to outpatient settings, especially for patients requiring outpatient parenteral antimicrobial therapy (OPAT) are complex. OPAT complications, such as adverse antimicrobial reactions, vascular access problems, and hospital readmissions are common. Data from transitions of care literature suggest that post-discharge telephone calls (TCs) may significantly decrease re-hospitalization but no studies have assessed the utility of post-discharge TCs as an OPAT program quality improvement process. Methods Adult OPAT patients discharged from our hospital between April 1, 2015 and May 31, 2016 were queried for post-discharge concerns. TCs to patients or their caregivers were administered by trained medical assistants within the Department of Infectious Diseases using a standardized script and documented in the electronic medical record (EMR). Feasibility was assessed using call completion rate. The type and frequency of reported issues were analyzed by retrospective chart review. Results 636 of 689 eligible adult OPAT patients or their caregivers received a TC with responses to scripted questions documented in the EMR (92% completion rate). 302 patients (47%) reported 319 issues, including 293 (92%) relevant to OPAT. Antimicrobial issues included diarrhea/stool changes (58; 9%); nausea/vomiting (27; 4%); and missed antimicrobial doses (22; 3%). Vascular access issues included line patency concerns (21; 3%); vascular access dressing problems (17; 2.6%) and arm pain/swelling (6; 1%). OPAT vendor issues included delays in lab or line care services (23; 4%) and OPAT orders reported as lost/not received (21; 3%). Other ID-related issues included fevers/chills/sweats (27; 4%), wound concerns (16; 2.5%), and pain (15; 2.5%). Conclusion Adding a post-discharge TC to an OPAT program was feasible and resulted in frequent and early identification of significant OPAT patient and caregiver concerns. Findings suggest potential high-yield topics for process improvement, as well as anticipatory guidance and patient education in OPAT. Further evaluation and analysis of optimal hospital discharge processes and care coordination in OPAT, as well as their impact on post-discharge adverse events, is needed.

The Difference

Background: Shifting inpatient antibiotic treatment to outpatient parenteral antimicrobial therapy may minimize treatment for acute bacterial skin and skin structure infections, including cellulitis. The purpose of this evaluation was to compare 30-day hospital readmission or admission due to cellulitis and economic outcomes of inpatient standard-of-care (SoC) management of acute uncomplicated cellulitis to outpatient oritavancin therapy. Methods: This retrospective, observational cohort study was conducted at a 941-bed community teaching hospital. Adult patients 18 years and older treated for acute uncomplicated cellulitis between February 2015 to December 2018 were eligible for inclusion. Information was obtained from hospital and billing department records. Patients were assigned to either inpatient SoC or outpatient oritavancin cohorts for comparison. Results: 1,549 patients were included in the study (1,348 in the inpatient SoC cohort and 201 in the outpatient oritavancin cohort). The average length of stay for patients admitted was 3.6 ± 1.5 days. The primary outcome of 30-day hospital readmission or admission due to cellulitis occurred in 49/1348 (3.6%) patients in the inpatient SoC cohort versus 1/201 (0.5%) in the outpatient oritavancin cohort (p = 0.02). The difference between costs and reimbursement was improved in the outpatient oritavancin group (p < 0.001). Conclusion: Outpatient oritavancin for acute uncomplicated cellulitis was associated with reduction in 30-day hospital readmissions or admissions compared to inpatient SoC. Beneficial economic outcomes for the outpatient oritavancin cohort were observed. Additional studies are required to confirm these findings.

Abstract Background medication-related problems occur frequently when older patients are discharged from hospital. Interventions to support medication use have been developed; however, their effectiveness in older populations are unknown. This review evaluates interventions that support successful transitions of care through enhanced medication continuity. Methods a database search for randomised controlled trials was conducted. Selection criteria included mean participant age of 65 years and older, intervention delivered during hospital stay or following recent discharge and including activities that support medication continuity. Primary outcome of interest was hospital readmission. Secondary outcomes related to the safe use of medication and quality of life. Outcomes were pooled by random-effects meta-analysis where possible. Results twenty-four studies (total participants = 17,664) describing activities delivered at multiple time points were included. Interventions that bridged the transition for up to 90 days were more likely to support successful transitions. The meta-analysis, stratified by intervention component, demonstrated that self-management activities (RR 0.81 [0.74, 0.89]), telephone follow-up (RR 0.84 [0.73, 0.97]) and medication reconciliation (RR 0.88 [0.81, 0.96]) were statistically associated with reduced hospital readmissions. Conclusion our results suggest that interventions that best support older patients’ medication continuity are those that bridge transitions; these also have the greatest impact on reducing hospital readmission. Interventions that included self-management, telephone follow-up and medication reconciliation activities were most likely to be effective; however, further research needs to identify how to meaningfully engage with patients and caregivers to best support post-discharge medication continuity. Limitations included high subjectivity of intervention coding, study heterogeneity and resource restrictions.

Prolonged Antibiotic Therapy

Abstract Hospitalizations for people who inject drugs (PWID) with infectious complications requiring prolonged antibiotic therapy are increasing in the context of the opioid epidemic. Although outpatient parenteral antimicrobial therapy (OPAT) is routinely offered to patients without a history of injection drug use (IDU), PWID are often excluded from consideration of OPAT. To better assess the evidence base for the safety and effectiveness of OPAT for PWID, we conducted a review of the published literature. Results suggest that OPAT may be safe and effective for PWID, with rates of OPAT completion, mortality, and catheter-related complications comparable to rates among patients without a history of IDU. Rates of hospital readmissions may be higher among PWID, but instances of misuse of the venous catheter were rarely reported. More research is needed to study the safety and effectiveness of OPAT among PWID, as well as studying the combination of OPAT and addiction treatment.

Abstract Background Outpatient parenteral antimicrobial therapy (OPAT) is a widely used, safe, and cost-effective treatment. Most public and private insurance providers require prior authorization (PA) for OPAT, yet the impact of the inpatient PA process is not known. Our aim was to characterize discharge barriers and PA delays associated with high-priced OPAT antibiotics. Methods This was an institutional review board–approved study of adult patients discharged with daptomycin, ceftaroline, ertapenem, and novel beta-lactam-beta-lactamase inhibitor combinations from January 2017 to December 2017. Patients with an OPAT PA delay were compared with patients without a delay. The primary endpoint was total direct hospital costs from the start of treatment. Results Two-hundred patients were included: 141 (71%) no OPAT delay vs 59 (30%) OPAT delay. More patients with a PA delay were discharged to a subacute care facility compared with an outpatient setting: 37 (63%) vs 52 (37%), P = .001. Discharge delays and median total direct hospital costs were higher for patients with OPAT delays: 31 (53%) vs 21 (15%), P &lt; .001 and $19 576 (interquartile range [IQR], 10 056–37 038) vs $7770 (IQR, 3031–13 974), P &lt; .001. In multiple variable regression, discharge to a subacute care facility was associated with an increased odds of discharge delay, age &gt;64 years was associated with a decreased odds of discharge delay. Conclusions OPAT with high-priced antibiotics requires significant care coordination. PA delays are common and contribute to discharge delays. OPAT transitions of care represent an opportunity to improve patient care and address access barriers.

Vancomycin Group

Abstract Background Vancomycin and daptomycin are commonly used in outpatient parenteral antimicrobial therapy (OPAT) for patients requiring lengthy courses of intravenous antimicrobials who are otherwise stable for discharge. Balancing the convenience and cost-savings of OPAT with the potential for adverse effects is challenging, this study compared the rates of complications and antimicrobial interventions for patients receiving vancomycin versus daptomycin across multiple OPAT settings. Methods We performed a retrospective chart review of adult OPAT patients who received &gt;72 hours of vancomycin or daptomycin via home infusion, infusion center, or skilled nursing facility between January 2017 and August 2019. The outcomes evaluated included the rates of adverse drug reactions (ADRs), laboratory results above a defined threshold (vancomycin levels &gt;20 mg/mL in the vancomycin arm and creatinine phosphokinase (CPK) levels &gt;500 units/L in the daptomycin group), line complications, emergency department (ED) visits, and hospital readmissions. Other outcomes included additional phone calls and interventions required to coordinate care (additional labs, assessment of symptoms, additional test or antimicrobial-related dose changes) by the OPAT team. Results 180 patients were included; 130 received vancomycin and 50 received daptomycin. (Table 1) Patients in the vancomycin group had more supratherapeutic vancomycin troughs than elevated CPK for patients in the daptomycin group (rate ratio [RR] 0.16, 95% CI 0.05-0.50, p=0.0018). Rates of interventions (RR 0.37, 95% CI 0.26-0.52, p&lt; 0.0001) and additional phone calls (RR 0.56, 95% CI 0.43-0.72, p&lt; 0.0001) were also higher for patients in the vancomycin group. There were no statistically significant differences between groups in the rates of ADRs, line complications, ED visits, or hospital readmissions. (Table 2) Table 1. Baseline Characteristics Table 2. Outcomes Conclusion Vancomycin-treated patients had significantly more laboratory abnormalities and required significantly more time in patient care coordination by the OPAT team. The difference in healthcare utilization between these groups suggests a potential for significant cost-savings for OPAT patients and the healthcare system.

Outpatient Parenteral Antimicrobial Therapy

Abstract Background Given current efforts to increase the safety of outpatient parenteral antimicrobial therapy (OPAT) programs nationwide, this project sought to determine whether pharmacist managed OPAT review and monitoring improves adherence to standard of care laboratory monitoring recommendations. Methods A single-center, retrospective review of patients &gt; 18 years of age who received OPAT from University Health System was conducted. Patients who received OPAT between October 2018 and December 2018 served as the historical control group. After a pharmacist transitions of care program was implemented, patients who received OPAT between October 2019 and December 2019 were included in the intervention group. Patients were excluded if they received less than 7 days of OPAT, completed therapy prior to discharge, or died while inpatient. The primary endpoint was adherence to laboratory monitoring recommendations &gt; 75% of the duration of planned OPAT. Only patients followed by the OPAT clinic were included in this analysis. Recommendations provided in the 2018 Infectious Diseases Society of America OPAT guidelines were used to define appropriate lab monitoring. Secondary endpoints included 30-day readmissions. Results A total of 409 patients were included in this study: 198 patients in the pre-implementation group and 211 patients in the post-implementation group. In patients with OPAT clinic follow-up, the post-implementation group was significantly more likely to receive monitoring adherent to standard of care laboratory monitoring recommendations &gt; 75% of the duration of planned OPAT: 42/161 (26.1%) vs. 98/176 (55.7%), OR 3.6 (95% CI 2.2-5.6, p = 0.0001). There was no difference in 30-day readmission rates between groups in the overall population. Patients in the post-implementation group with OPAT clinic follow up had lower 30-day infectious disease-attributed readmissions: 18/161 (11.2%) vs. 14/176 (8.0%), p = 0.31. Conclusion Implementation of a transitions of care pharmacist significantly improved adherence to laboratory monitoring recommendations for patients receiving OPAT and numerically reduced 30-day infectious disease-attributed readmissions.
