Real-World Budget Impact of Fidaxomicin versus Vancomycin or Metronidazole for In-Hospital Treatment of Clostridioides difficile Infection

Fidaxomicin, a macrocyclic antibiotic, selectively kills Clostridioides difficile and reduces C. difficile infection (CDI) recurrence compared with vancomycin, but some studies and guidelines report fidaxomicin as being less cost-effective. The aim of this study was to compare the cost-effectiveness and budget impact of fidaxomicin versus vancomycin or metronidazole for treating CDI in a real-world UK setting. Data were retrospectively collected from medical records of 86 patients with CDI treated with vancomycin or metronidazole at a single UK hospital between April 2011 and March 2012, and prospectively from 62 patients with CDI treated with fidaxomicin between August 2012 and July 2013. CDI cases were matched by age, financial year, and healthcare resource use to control cases. CDI recurrence rates were lower with fidaxomicin (6.5%) than vancomycin/metronidazole (19.8%). An estimated 12 additional recurrent CDIs were prevented with fidaxomicin treatment. Patients with CDI had significantly higher healthcare costs than those without CDI, with a mean excess spend of GBP 10,748 and GBP 17,451 per patient in the fidaxomicin (p = 0.015) and vancomycin/metronidazole cohorts (p < 0.001), respectively. A second CDI was associated with mean excess costs of GBP 8373 and GBP 20,249 per patient in the fidaxomicin and vancomycin/metronidazole cohorts, respectively. Despite higher fidaxomicin drug costs, overall cost savings were estimated at GBP 140,292 (GBP 2125 per CDI). In this real-world study, first-line CDI treatment with fidaxomicin reduced healthcare costs versus vancomycin/metronidazole, consistent with previous studies.

Assessment and Management of Delirium in Critically Ill Veterans.

BACKGROUND: Delirium is a complex syndrome prevalent in the intensive care unit. It has been associated with significant morbidity including distress, longer hospital stays, prolonged cognitive impairment, and increased mortality. OBJECTIVE: To describe a nurse-led interdisciplinary quality improvement initiative to increase nurses' knowledge of delirium, documentation of delirium assessment, and patient mobility. METHODS: Sixty-seven nurses in medical and surgical intensive care units were required to attend an interactive education program on delirium assessment and management. Scores on tests taken before and after the education program were used to evaluate knowledge. Medical records and bedside rounds were used to validate Confusion Assessment Method for the Intensive Care Unit documentation and interventions. Descriptive statistics were used to describe changes over time. A delirium resource team composed of nurses, physicians, and therapists provided didactic education paired with simulation training and bedside coaching. Mobility screening tests and computer templates guided assessments and interventions. RESULTS: Documentation of the Confusion Assessment Method improved from less than 50% to consistently 99%. Mobilization in the surgical intensive care unit increased from 90% to 98% after intervention. Days of delirium significantly decreased from 51% before intervention to 31% after intervention (χ12=7.01, P = .008). CONCLUSIONS: The success of this quality improvement project to enhance recognition of delirium and increase mobility (critical components of the pain assessment, breathing, sedation choice, delirium, early mobility, and family education bundle) was contingent on nursing leaders hip, interdisciplinary team collaboration, and interactive education.

Effectiveness of an antifungal stewardship programme at a London teaching hospital 2010-16.

Background: The need for antifungal stewardship is gaining recognition with increasing incidence of invasive fungal infection (IFI) and antifungal resistance alongside the high cost of antifungal drugs. Following an audit showing suboptimal practice we initiated an antifungal stewardship programme and prospectively evaluated its impact on clinical and financial outcomes. Patients and methods: From October 2010 to September 2016, adult inpatients receiving amphotericin B, echinocandins, intravenous fluconazole, flucytosine or voriconazole were reviewed weekly by an infectious diseases consultant and antimicrobial pharmacist. Demographics, diagnosis by European Organization for Research and Treatment of Cancer (EORTC) criteria, drug, indication, advice, acceptance and in-hospital mortality were recorded. Antifungal consumption and expenditure, and candidaemia species and susceptibility data were extracted from pharmacy and microbiology databases. Results: A total of 432 patients were reviewed, most commonly receiving AmBisome® (35%) or intravenous fluconazole (29%). Empirical treatment was often unnecessary, with 82% having no evidence of IFI. Advice was given in 64% of reviews (most commonly de-escalating or stopping treatment) and was followed in 84%. Annual antifungal expenditure initially reduced by 30% (£0.98 million to £0.73 million), then increased to 20% above baseline over a 5 year period; this was a significantly lower rise compared with national figures, which showed a doubling of expenditure over the same period. Inpatient mortality, Candida species distribution and rates of resistance were not adversely affected by the intervention. Conclusions: Provision of specialist input to optimize antifungal prescribing resulted in significant cost savings without compromising on microbiological or clinical outcomes. Our model is readily implementable by hospitals with high numbers of at-risk patients and antifungal expenditure.
