Abstract Background Isavuconazole is an azole antifungal with in vitro activity against various fungi, including Candida spp, Aspergillus, and Mucormycetes. Currently, isavuconazole is FDA approved for the treatment of invasive aspergillosis and mucormycosis; however, there remains limited data to support prophylaxis use. Compared with other first-line azoles, isavuconazole’s broad spectrum of activity, favorable safety profile, and oral bioavailability makes it an attractive antifungal option. In July 2017, isavuconazole was added to our hospital formulary as a restricted antimicrobial. Since then, we have seen increased use for both prophylaxis and treatment of invasive fungal infections. Methods A single-center, retrospective chart review was conducted on adult patients who received at least 1 dose of isavuconazole at The Mount Sinai Hospital between July 1, 2017 and December 31, 2018. The electronic medical record was utilized to collect information on therapeutic indication, dosing, formulation, duration, reasons for switching to isavuconazole, prior antifungals, and proven or probable breakthrough invasive fungal infections (bIFIs) based on EORTG/MTG definitions. Results 54 patients received 61 courses of isavuconazole. Reasons for switching to isavuconazole are described in Table 1. Eleven patients received inappropriate intravenous formulations and 14% of orders were prescribed isavuconazole without a loading dose (Table 2). We identified 4 proven/probable bIFIs, representing 7.4% of patients and 6.6% of courses (Table 3). All patients died within 60 days of bIFI onset. Conclusion Since its addition to hospital formulary, we have observed varying isavuconazole prescribing practices, highlighting the need for improved antifungal stewardship. Rates of bIFIs on isavuconazole were lower than previously reported studies. Additional studies are needed to provide guidance on isavuconazole use and determine its role as prophylaxis therapy.

Abstract Background Isavuconazonium is an appealing anti-fungal due to its broad spectrum of activity, predictable pharmacokinetics, oral bioavailability, and lack of QTc prolongation, but real-world experience with it is limited. At our academic medical center, isavuconazonium is restricted to the infectious diseases (ID) service for treatment of invasive fungal infections, including endemic mycoses due to high prevalence, and is recommended for patients intolerant of first-line agents. The purpose of this study was to describe isavuconazonium use at our institution and assess adherence to its formulary guidelines. Methods Inpatients with an order for isavuconazonium between June 2016 and November 2018 were analyzed via retrospective chart review. Prescribing team, indication, and rationale for use were evaluated. Results There were 97 inpatient encounters with an isavuconazonium order among 57 patients. Of those, 30 were solid-organ transplants and 9 had bone marrow transplants. Indications for isavuconazonium were: histoplasmosis 25%, high-risk fungal prophylaxis 21%, invasive aspergillosis 9%, candidiasis 2%, and other 44% (Table 1). Preceding anti-fungal therapy included: voriconazole 49%, posaconazole 12%, fluconazole 9%, micafungin 7%, amphotericin B 5%, itraconazole 4%, and none 35%. The rationale for the use of isavuconazonium is described in Table 2. ID consultation occurred in 79% of patients. Those without a consult had an indication of prophylaxis or were continuation of therapy started outpatient or at an outside hospital (OSH). Conclusion Histoplasmosis was the most common infection treated with isavuconazonium, despite limited data for that indication. Further investigation of the clinical course for these patients is warranted. Reasons for use most commonly centered on concern for QTc prolongation, clinical failure, and drug interactions. Over one-third of patients received no anti-fungal therapy prior to initiation. Adherence to required ID consultation was high. Patients on isavuconazonium for prophylaxis or as continuation therapy without a consult may still benefit from ID review to assess the appropriateness of therapy.

Background Obtaining wrist radiographs prior to surgeon evaluation may be wasteful for patients ultimately diagnosed with de Quervain tendinopathy (DQT). Questions/Purpose Our primary question was whether radiographs directly influence treatment of patients presenting with DQT. A secondary question was whether radiographs influence the frequency of injection and surgical release between cohorts with and without radiographs evaluated within the same practice. Patients and Methods Patients diagnosed with DQT by fellowship-trained hand surgeons at an urban academic medical center were identified retrospectively. Basic demographics and radiographic findings were tabulated. Clinical records were studied to determine whether radiographic findings corroborated history or physical examination findings, and whether management was directly influenced by radiographic findings. Frequencies of treatment with injection and surgery were separately tabulated and compared between cohorts with and without radiographs. Results We included 181 patients (189 wrists), with no differences in demographics between the 58% (110 wrists) with and 42% (79 wrists) without radiographs. Fifty (45%) of imaged wrists demonstrated one or more abnormalities; however, even for the 13 (12%) with corroborating history and physical examination findings, wrist radiography did not directly influence a change in management for any patient in this series. No difference was observed in rates of injection or surgical release either upon initial presentation, or at most recent documented follow-up, between those with and without radiographs. No differences in frequency, types, or total number of additional simultaneous surgical procedures were observed for those treated surgically. Conclusion Wrist radiography does not influence management of patients presenting DQT. Level of Evidence This is a level III, diagnostic study.
