Cost evaluation of continuation of therapy with dalbavancin compared to standard-of-care antibiotics alone in hospitalized persons who inject drugs with severe gram-positive infections. Am J Health Syst Pharm 2024; 81:S40-S48.

Abstract
PURPOSE Persons who inject drugs (PWID) are at risk for severe gram-positive infections and may require prolonged hospitalization and intravenous (IV) antibiotic therapy. Dalbavancin (DBV) is a long-acting lipoglycopeptide that may reduce costs and provide effective treatment in this population. METHODS This was a retrospective review of PWID with severe gram-positive infections. Patients admitted from January 1, 2017, to November 1, 2019 (standard-of-care [SOC] group) and from November 15, 2019, to March 31, 2022 (DBV group) were included. The primary outcome was the total cost to the healthcare system. Secondary outcomes included hospital days saved and treatment failure. RESULTS A total of 87 patients were included (37 in the DBV group and 50 in the SOC group). Patients were a median of 34 years old and were predominantly Caucasian (82%). Staphylococcus aureus (82%) was the most common organism, and bacteremia (71%) was the most common type of infection. Compared to the SOC group, the DBV group would have had a median of 14 additional days of hospitalization if they had stayed to complete their therapy (P = 0.014). The median total cost to the healthcare system was significantly lower in the DBV group than in the SOC group ($31,698.00 vs $45,093.50; P = 0.035). The rate of treatment failure was similar between the groups (32.4% in the DBV group vs 36% in the SOC group; P = 0.729). CONCLUSION DBV is a cost-saving alternative to SOC IV antibiotics for severe gram-positive infections in PWID, with similar treatment outcomes. Larger prospective studies, including other patient populations, may demonstrate additional benefit.

Outpatient care concept and potential inpatient cost savings associated with the administration of dalbavancin - A real-world data and retrospective cost analysis. J Infect Public Health 2023; 16:955-963. [PMID: 37099955 DOI: 10.1016/j.jiph.2023.04.015] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/08/2022] [Revised: 04/02/2023] [Accepted: 04/13/2023] [Indexed: 04/28/2023] Open
Abstract
BACKGROUND The treatment of acute bacterial skin and skin structure infections (ABSSSI) usually involves intravenous (i.v.) antibiotics requiring hospitalisation and increasing hospital costs. Since 2014, dalbavancin is approved for ABSSSIs treatment. However, evidence of its health economic impact on the German healthcare system is still limited. METHODS Diagnosis-related groups (DRG) based cost analysis was used to evaluate real-world data (RWD) from a German tertiary care center. All patients treated with i.v. antibiotics in the Department of Dermatology and Venereology at the University Hospital of Cologne were included to detect potential cost savings from a payer perspective. Thus, for the inpatient care German diagnosis-related groups (G-DRG) tariffs, length of stay (LOS), main- and secondary DRG-diagnoses and for the outpatient setting 'Einheitlicher Bewertungsmaßstab' (EBM) codes were evaluated. RESULTS This retrospective study identified 480 inpatient cases treated for ABSSSI between January 2016 until December 2020. Complete cost data were available for 433 cases and the detection of long-hospital-stay patients based on surcharges for exceeding the upper limit LOS led to 125 cases (29%) including 67 females (54%) and 58 males (46%) with an overall mean age of 63.6 years; all treated for International Classification of Diseases (ICD -10th revision) code A46 'erysipelas'. A sub-analysis focussed on DRG J64B with a total of 92 cases exceeding the upper limit LOS by a median of 3 days resulted in a median surcharge of €636 (mean value €749; SD €589; IQR €459-€785) per case. In comparison, we calculated outpatient treatment costs of approximately €55 per case. Thus, further treatment of these patients in an outpatient setting before exceeding the upper limit LOS might result in a cost-saving potential of approximately €581 per case. CONCLUSION Dalbavancin appears a cost-efficient option to reduce inpatient treatment costs by transitioning to an outpatient setting of patients with ABSSSI potentially exceeding the upper limit LOS.

Cost analysis of dalbavancin versus standard of care for the treatment of acute bacterial skin and skin structure infections (ABSSSIs) in two Italian hospitals. JAC Antimicrob Resist 2023; 5:dlad044. [PMID: 37090914 PMCID: PMC10116602 DOI: 10.1093/jacamr/dlad044] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/23/2023] [Accepted: 03/25/2023] [Indexed: 04/25/2023] Open
Abstract
Objectives Thanks to its long half-life, dalbavancin qualifies as an optimal drug for saving costs. We aimed to assess the cost and effectiveness of dalbavancin versus the standard of care (SoC). Patients and methods We conducted a multicentre retrospective study, including all hospitalized or outpatients diagnosed with ABSSSIs at Padua University Hospital, Padua and San Paolo Hospital, Milan (1 January 2016 to 31 July 2020). We compared patients according to antibiotic treatment (dalbavancin versus SoC), the number of lines of dalbavancin treatment, and monotherapy or combination (dalbavancin in association with other antibiotics). Primary endpoints were direct medical costs and length of hospital stay (LOS) associated with ABSSSI management; Student's t-test, chi-squared test and one-way ANOVA were used. Results One hundred and twenty-six of 228 (55.3%) patients received SoC, while 102/228 (44.7%) received dalbavancin. Twenty-seven of the 102 (26.5%) patients received dalbavancin as first-line treatment, 46 (45.1%) as second-line, and 29 (28.4%) as third- or higher-line treatment. Most patients received dalbavancin as monotherapy (62/102; 60.8%). Compared with SoC, dalbavancin was associated with a significant reduction of LOS (5 ± 7.47 days for dalbavancin, 9.2 ± 5.59 days for SoC; P < 0.00001) and with lower mean direct medical costs (3470 ± 2768€ for dalbavancin; 3493 ± 1901€ for SoC; P = 0.9401). LOS was also reduced for first-line dalbavancin, in comparison with second-, third- or higher-line groups, and for dalbavancin monotherapy versus combination therapy. Mean direct medical costs were significantly lower in first-line dalbavancin compared with higher lines, but no cost difference was observed between monotherapy and combination therapy. Conclusions Monotherapy with first-line dalbavancin was confirmed as a promising strategy for ABSSSIs in real-life settings, thanks to its property in reducing LOS and saving direct medical costs.

Abstract
Dalbavancin is a second-generation lipoglycopeptide antibiotic with activity against Gram-positive organisms. Dalbavancin is Food and Drug Administration (FDA)-approved for acute bacterial skin and soft tissue infections (ABSSTIs). There is a lack of substantial data on dalbavancin in more invasive infections, particularly in high-risk populations (patients with intravenous drug use and unstable living conditions). In this retrospective observational study, we reviewed all patients that received at least one dose of dalbavancin in an inpatient or outpatient setting at Parkland Hospital from February of 2019 to August of 2021. The demographics, type of infection, and rationale for dalbavancin were collected at the baseline. Clinical failure was measured by an avoidance of emergency department (ED) visits or hospital readmission at 30, 60, and 90 days. A separate analysis was conducted to estimate hospital, rehabilitation, or nursing facility days saved based on the projected length of treatment. 40 patients were included, and the majority were uninsured (85%), experiencing homelessness (60%), or had intravenous drug use (IDU) (57.5%). Indications for use included ABSSTIs (45%), bloodstream infection (67.5%), osteomyelitis (40%), infective endocarditis (10%), and septic arthritis (10%). Clinical failure was observed in 5 of the 40 patients (12.5%). Nonadherence to medical recommendations, a lack of source control, and ongoing IDU increased the risk of failure. Dalbavancin saved a total of 566 days of inpatient, rehabilitation, and nursing facility stays. Dalbavancin is a reasonable alternative to the standard of care in an at-risk population, offering decreased lengths of stays and cost savings. The uses of second-generation lipoglycopeptides are desirable alternatives to traditional outpatient parenteral antibiotic therapies for patients who otherwise would not qualify or for patients who desire less hospital contact in light of the COVID-19 pandemic. IMPORTANCE This study contributes additional experience to the literature of dalbavancin use in off-label indications, particularly for patients who do not qualify for outpatient parenteral antimicrobial therapy. The majority of the patient population were people who inject drugs and the uninsured. There is difficulty in tracking outcomes in this patient population, given their outpatient follow-up rates; however, we were able to track emergency room visits and readmissions throughout the majority of the local metroplex. The clinical use of dalbavancin at our institution also increased in the midst of the COVID-19 pandemic in an effort to preserve hospital resources and limit health care exposure. In addition, we are able to provide institution-specific cost-saving data with the use of dalbavancin.

Abstract
Hospitalisation rates for acute bacterial skin and skin structure infection (ABSSSI) are rising and represent a large pharmacoeconomic burden as treatment may involve an extended number of days of antibiotic therapy. This article first aims to provide a review of treatment challenges associated with ABSSSIs in both hospital and outpatient settings, and shows that while more traditionally treatment has been conducted in a hospital setting, for a number of patients, a variety of considerations, including pharmacoeconomics, infection control, and patient preference, has led to the development of recommendations to assess the eligibility of patients for early discharge from hospital to complete their antibiotic regimen in the outpatient setting. However, such patients require monitoring for drug adherence to oral regimens or complications associated with daily intravenous administration, such as injection site reactions and infection. This review also focuses on one of a number of new antibiotics for ABSSSI, dalbavancin, as the long-acting glycopeptide with the most clinical experience to date. This antibiotic has been shown to be as effective as a daily/twice daily regimen with similar safety profiles. Health economic analysis of dalbavancin is also presented. It has shown that in some, though not all, clinical settings a reduction in the overall treatment cost is evident as, despite a higher medication cost, the lower hospitalisation time can lead to greater cost savings. In conclusion, while the burden of ABSSSI is rising, new treatment options provide additional therapeutic choice, although pharmacoeconomic considerations might limit use in some cases.

Abstract
Bacterial skin and soft tissue infections are among the most common bacterial infections and constitute a major burden for patients and healthcare systems. Care is complicated by the variety of potential pathogens, some with resistance to previously effective antimicrobial agents, the wide spectrum of clinical presentations and the risk of progression to life-threatening forms. More-efficient care pathways are needed that can reduce hospital admissions and length of stay, while maintaining a high quality of care and adhering to antimicrobial stewardship principles. Several agents approved recently for treating acute bacterial skin and skin structure infections have characteristics that meet these requirements. We address the clinical and pharmacological characteristics of the fourth-generation fluoroquinolone delafloxacin, and the long-acting lipoglycopeptide agents dalbavancin and oritavancin.

Abstract
PURPOSE OF REVIEW To discuss the currently available evidence about the use oritavancin and dalbavancin for the treatment of acute bacterial skin and skin structure infections (ABSSSI) and for other potential indications. RECENT FINDINGS In this review, we briefly summarize the available data on efficacy (from randomized controlled trials) and on effectiveness and cure rates (from observational studies) pertaining to the use of oritavancin and dalbavancin either for ABSSSI or for other indications. SUMMARY Oritavancin and dalbavancin are valid options for outpatient therapy and early discharge in patients with ABSSSI, especially when adherence to oral therapy cannot be guaranteed or no oral choices are available. Furthermore, it is worth noting that a non-negligible portion (sometimes the majority) of oritavancin and dalbavancin use in available real-life experiences is for indications other than ABSSSI, especially for Gram-positive osteomyelitis and endocarditis. The number of studies on the use of long-acting lipoglycopeptides for these currently off-label indications is rapidly increasing and will help to further optimize the use of these peculiar antibiotics in the forthcoming future.

Abstract
Dalbavancin (DAL) is a lipoglycopeptide with bactericidal activity against a very wide range of Gram-positive microorganisms. It also has unique pharmacokinetic properties, namely a prolonged half-life (around 181 h), which allows a convenient weekly dosing regimen, and good diffusion in bone tissue. These features have led to off-label use of dalbavancin in the setting of bone and joint infection, including prosthetic joint infections (PJI). In this narrative review, we go over the pharmacokinetic and pharmacodynamic characteristics of DAL, along with published in vitro and in vivo experimental models evaluating its activity against biofilm-embedded bacteria. We also examine published experience of osteoarticular infection with special attention to DAL and PJI.
