Use of Oritavancin in Acute Bacterial Skin and Skin Structure Infections Patients Receiving Intravenous Antibiotics: A US Hospital Budget Impact Analysis.

ABSTRACT:

Background and objective

Nearly 10% of all US hospital admissions are attributed to acute bacterial skin and skin structure infections (ABSSSIs). While most antibacterials used to treat these infections require multi-day and multi-dose regimens, a single-dose treatment is now available. The objective of this analysis is to estimate the annual budget impact of using single-dose oritavancin in patients with moderate to severe ABSSSIs receiving intravenous methicillin-resistant Staphylococcus aureus (MRSA)-active antibacterials from a US hospital perspective.

Methods

A decision-analytic model based on current clinical practice was developed to estimate the economic impact of oritavancin. Utilization of antibacterials and rates of hospital admission were derived from the Premier Research Database. Demographic and clinical data were informed by the published literature and 2014 wholesale drug acquisition costs were used. Other costs were based on the published literature and Medicare National Limitation amounts. All costs were inflated to 2014 US dollars. Two base-case scenarios were considered: one for hospitals with ambulatory services and one for hospitals without ambulatory services.

Results

For a US hospital with ambulatory services with 1000 ABSSSI patients receiving intravenous MRSA antibiotics annually, use of oritavancin in 26% of patients is estimated to reduce the total annual budget by 12.9% (US$1.23 million), or approximately US$1234.67 per patient. Total inpatient costs will be reduced by 22.3% (US$1.40 million) and outpatient costs will increase slightly by 1.7% (US$55,310). Pharmaceutical cost increases are offset by savings in the inpatient setting from fewer hospital admissions. Hospitals without ambulatory services are estimated to receive overall cost savings of 9.3% (US$0.63 million).

Conclusion

Use of single-dose oritavancin in select ABSSSI patients with suspected or confirmed MRSA involvement is estimated to save US hospitals approximately 9.3-12.9% per year by reducing hospital admissions and lowering drug administration burden.

Project description:BackgroundOritavancin is a lipoglycopeptide antibiotic with in vitro bactericidal activity against gram-positive pathogens indicated for use in adults with acute bacterial skin and skin structure infections (ABSSSI). Its concentration-dependent activity and prolonged half-life provide a convenient single-dose alternative to multi-dose daily therapies for ABSSSI. This retrospective cohort study was conducted to quantify the clinical and economic advantages of using oritavancin compared to other antibiotic agents that have been historically effective for ABSSSI.MethodsSeventy-nine patients received oritavancin who had failed previous outpatient antibiotic therapy (OPAT) for cellulitis or abscess and were subsequently readmitted to the hospital as an inpatient between 2016 and 2018. These patients were compared to a cohort of 28 patients receiving other antibiotics following OPAT failure and subsequent hospitalization for these two infection types. The primary clinical end point was average length of stay (aLOS) and secondary endpoints included readmission rates for the same indication at 30 and 90 days after discharge and the average hospital cost (aHC).ResultsA total of 107 patients were hospitalized for treatment of cellulitis or abscess. Demographic characteristics of both the oritavancin and comparator groups were similar except for the presence of diabetes. The primary clinical endpoint showed a non-significant decrease in aLOS between the oritavancin group versus comparator (2.12 days versus 2.59 days; p = 0.097). The secondary endpoints revealed lower readmission rates associated with oritavancin treatment at 30 and 90 days; the average hospital cost was 5.9% lower for patients that received oritavancin.ConclusionThe results of this study demonstrate that oritavancin provides not only a single-dose alternative to multi-day therapies for skin and skin structure infections, but also a clinical and economic advantage compared to other antibiotic agents.

Project description:IntroductionIntroduction of new antibiotics enabling single-dose administration, such as oritavancin may significantly impact site of care decisions for patients with acute bacterial skin and skin structure infections (ABSSSI). This analysis compared the efficacy of single-dose oritavancin with multiple-dose vancomycin in patients categorized according to disease severity via modified Eron classification and management setting.MethodsSOLO I and II were phase 3 studies evaluating single-dose oritavancin versus 7-10 days of vancomycin for treatment of ABSSSI. Patient characteristics were collected at baseline and retrospectively analyzed. Study protocols were amended, allowing outpatient management at the discretion of investigators. In this post hoc analysis, patients were categorized according to a modified Eron severity classification and management setting (outpatient vs. inpatient) and the efficacy compared.ResultsOverall, 1910 patients in the SOLO trials were categorized into Class I (520, 26.5%), II (790, 40.3%), and III (600, 30.6%). Of the 767 patients (40%) in the SOLO trials who were managed entirely in the outpatient setting 40.3% were categorized as Class II and 30.6% were Class III. Clinical efficacy was similar between oritavancin and vancomycin treatment groups, regardless of severity classification and across inpatient and outpatient settings. Class III patients had lower response rates (oritavancin 73.3%, vancomycin 76.6%) at early clinical evaluation when compared to patients in Class I (82.6%) or II (86.1%); however, clinical cure rates at the post-therapy evaluation were similar for Class III patients (oritavancin 79.8%, vancomycin 79.9%) when compared to Class I and II patients (79.1-85.7%).ConclusionSingle-dose oritavancin therapy results in efficacy comparable to multiple-dose vancomycin in patients categorized according to modified Eron disease severity classification regardless of whether management occurred in the inpatient or outpatient setting.FundingThe Medicines Company, Parsippany, NJ, USA.Trial registrationClinicalTrials.gov identifiers, NCT01252719 (SOLO I) and NCT01252732 (SOLO II).

Project description:IntroductionAcute bacterial skin and skin structure infections (ABSSSIs) are frequently treated in emergency departments (EDs) or observation units (OUs) initially with intravenous (IV) antibiotics before discharge on oral therapy. This study aims to describe ABSSSI patients discharged directly from EDs/OUs.MethodsThis is a retrospective cohort study of patients with ABSSSIs treated in EDs/OUs of the Detroit Medical Center from 2012 to 2014. Adults with less than 24 h of IV antibiotics without hospital admission were included. Demographics, clinical characteristics, and severity were compared between ED and OU patients. Resource utilization, including tissue and blood cultures, and use of radiographic analysis was also collected. The primary outcome was 96-h ED revisit/hospitalization.ResultsAnalysis included 308 patients; 219 ED and 89 OU. OU patients were significantly more likely to be obese, have COPD/asthma, be diagnosed with cellulitis, and meet at least one systemic inflammatory response syndrome (SIRS) criterion. Tissue cultures were obtained in 21.7% of abscesses in the ED; 67.9% were in uncomplicated abscesses. In the OU tissue cultures were obtained in 48.8% of abscesses and 37.5% were uncomplicated cases. Blood cultures were drawn in 18.3% of ED patients and 56.2% of OU patients, not significantly associated with the presence of SIRS criteria. Radiology was used in the diagnosis of ABSSSIs in 33.5% of ED versus 69.5% OU patients (p < 0.001), Plain film radiograph being the most common. Thirty patients revisited the ED or required hospitalization within 96 h, 23 from the ED (p = 0.479). Prior history of ABSSSI (adjusted odds ratio [aOR] = 2.382, 95% confidence interval [CI] 1.264-6.346) and location on torso/buttocks (aOR = 2.355, 95% CI 1.067-5.197) were independent predictors.ConclusionsThe low rate of ED revisit/hospitalization supports the use of OUs for low acuity ABSSSIs requiring initial IV therapy. Resource utilization within EDs/OUs for the management of ABSSSIs needs to be evaluated for unnecessary testing/procures.
