Current Epidemiology and Clinical Features of Cryptococcus Infection in Patients Without Human Immunodeficiency Virus: A Multicenter Study in 46 Hospitals in Australia and New Zealand.

BACKGROUND: Patients without human immunodeficiency virus (HIV) are increasingly recognized as being at risk for cryptococcosis. Knowledge of characteristics of cryptococcosis in these patients remains incomplete. METHODS: We conducted a retrospective study of cryptococcosis in 46 Australian and New Zealand hospitals to compare its frequency in patients with and without HIV and describe its characteristics in patients without HIV. Patients with cryptococcosis between January 2015 and December 2019 were included. RESULTS: Of 475 patients with cryptococcosis, 90% were without HIV (426 of 475) with marked predominance in both Cryptococcus neoformans (88.7%) and Cryptococcus gattii cases (94.3%). Most patients without HIV (60.8%) had a known immunocompromising condition: cancer (n = 91), organ transplantation (n = 81), or other immunocompromising condition (n = 97). Cryptococcosis presented as incidental imaging findings in 16.4% of patients (70 of 426). The serum cryptococcal antigen test was positive in 85.1% of tested patients (319 of 375); high titers independently predicted risk of central nervous system involvement. Lumbar puncture was performed in 167 patients to screen for asymptomatic meningitis, with a positivity rate of 13.2% where meningitis could have been predicted by a high serum cryptococcal antigen titer and/or fungemia in 95% of evaluable cases. One-year all-cause mortality was 20.9% in patients without HIV and 21.7% in patients with HIV (P = .89). CONCLUSIONS: Ninety percent of cryptococcosis cases occurred in patients without HIV (89% and 94% for C. neoformans and C. gattii, respectively). Emerging patient risk groups were evident. A high level of awareness is warranted to diagnose cryptococcosis in patients without HIV.

Impact of Erg11 Amino Acid Substitutions Identified in Candida auris Clade III Isolates on Triazole Drug Susceptibility.

ERG11 sequencing of 28 Candida auris clade III isolates revealed the presence of concomitant V125A and F126L substitutions. Heterologous expression of Erg11-V125A/F126L in Saccharomyces cerevisiae led to reduced fluconazole and voriconazole susceptibilities. Generation of single substitution gene variants through site-directed mutagenesis uncovered that F126L primarily contributes to the elevated triazole MICs. A similar yet diminished pattern of reduced susceptibility was observed with the long-tailed triazoles posaconazole and itraconazole for the V125A/F126L, F126L, Y132F, and K143R alleles.

Antifungal use via outpatient parenteral antimicrobial therapy.

BACKGROUND: Antifungal administration via outpatient parenteral antimicrobial therapy (OPAT) is infrequent. As patients with invasive fungal infections (IFIs) receiving OPAT are at high risk of readmissions, careful, risk-based patient selection and monitoring is important. OBJECTIVES: To describe our experience managing IFIs via OPAT, including assessment of risk factors associated with unplanned readmissions. PATIENTS AND METHODS: A retrospective cohort study of outpatients from two tertiary hospitals in Western Australia managed with parenteral antifungals for the treatment of IFIs from 2012 to 2020. Outcomes assessed were unplanned OPAT-related readmissions; adverse events and achievement of treatment aim at the completion of OPAT. RESULTS: Forty-six patients were included, encompassing 696 OPAT days. Twenty-three (50%) patients received intravenous (IV) liposomal amphotericin B (L-AmB), 23 (50%) received IV echinocandins and one (2%) patient received IV fluconazole. One patient received both IV L-AmB and an echinocandin. Unplanned OPAT-related readmissions occurred in 13 (28%) patients and any adverse event occurred in 19 (41%), most commonly nephrotoxicity amongst patients receiving L-AmB. On univariate analysis, unplanned OPAT-related readmissions were more common in Mucorales infection, L-AmB doses of ≥5 mg/kg and otorhinolaryngologic (ENT) infections. At the completion of OPAT, attainment of treatment aims occurred in 28 (61%) patients. CONCLUSIONS: Patients receiving parenteral antifungals via OPAT experience high rates of unplanned readmissions and adverse events. Risk factor identification may facilitate optimal patient selection and establishment of treatment aims.

Consensus guidelines for the diagnosis and management of cryptococcosis and rare yeast infections in the haematology/oncology setting, 2021.

Cryptococcosis caused by the Cryptococcus neoformans-Cryptococcus gattii complex is an important opportunistic infection in people with immunodeficiency, including in the haematology/oncology setting. This may manifest clinically as cryptococcal meningitis or pulmonary cryptococcosis, or be detected incidentally by cryptococcal antigenemia, a positive sputum culture or radiological imaging. Non-Candida, non-Cryptococcus spp. rare yeast fungaemia are increasingly common in this population. These consensus guidelines aim to provide clinicians working in the Australian and New Zealand haematology/oncology setting with clear guiding principles and practical recommendations for the management of cryptococcosis, while also highlighting important and emerging rare yeast infections and their recommended management.

Candida auris Sternal Osteomyelitis in a Man from Kenya Visiting Australia, 2015.

In Australia in 2015, Candida auris sternal osteomyelitis was diagnosed in a 65-year-old man with a history of intensive care treatment in Kenya in 2012 and without a history of cardiac surgery. The isolate was South Africa clade III. Clinicians should note that C. auris can cause low-grade disease years after colonization.

Diagnosis, management and prevention of Candida auris in hospitals: position statement of the Australasian Society for Infectious Diseases.

Candida auris is an emerging drug-resistant yeast responsible for hospital outbreaks. This statement reviews the evidence regarding diagnosis, treatment and prevention of this organism and provides consensus recommendations for clinicians and microbiologists in Australia and New Zealand. C. auris has been isolated in over 30 countries (including Australia). Bloodstream infections are the most frequently reported infections. Infections have crude mortality of 30-60%. Acquisition is generally healthcare-associated and risks include underlying chronic disease, immunocompromise and presence of indwelling medical devices. C. auris may be misidentified by conventional phenotypic methods. Matrix-assisted laser desorption ionisation time-of-flight mass spectrometry or sequencing of the internal transcribed spacer regions and/or the D1/D2 regions of the 28S ribosomal DNA are therefore required for definitive laboratory identification. Antifungal drug resistance, particularly to fluconazole, is common, with variable resistance to amphotericin B and echinocandins. Echinocandins are currently recommended as first-line therapy for infection in adults and children ≥2 months of age. For neonates and infants <2 months of age, amphotericin B deoxycholate is recommended. Healthcare facilities with C. auris should implement a multimodal control response. Colonised or infected patients should be isolated in single rooms with Standard and Contact Precautions. Close contacts, patients transferred from facilities with endemic C. auris or admitted following stay in overseas healthcare institutions should be pre-emptively isolated and screened for colonisation. Composite swabs of the axilla and groin should be collected. Routine screening of healthcare workers and the environment is not recommended. Detergents and sporicidal disinfectants should be used for environmental decontamination.

Successful outpatient parenteral antibiotic therapy delivery via telemedicine.

Objectives: Most outpatient parenteral antimicrobial therapy (OPAT) services use a hospital-based model of care in which patients remain in proximity to large hospitals facilitating clinical review. We aimed to evaluate clinical outcomes and complication rates for patients living in geographically isolated locations managed by telemedicine-supported OPAT. Methods: This was a retrospective cohort study. Results: Between 2011 and 2015, we delivered 88 episodes of care involving 83 adult patients resulting in 2261 days of OPAT. The median age was 56 years, 8 of 83 (10%) were indigenous Australian and the median Charlson comorbidity index score was 2 (IQR 1-4). The median distance of patients' residence from our hospital was 288 km (IQR 201-715) and the median duration on the programme was 26 days (IQR 14-34). Bone and joint infections accounted for 75% of infections treated. Favourable clinical outcomes (improvement or cure) were achieved in 87% of patients and the unplanned, OPAT-related readmission rate was 8%. Nineteen percent and 10% of patients had drug-related and line-related adverse effects, respectively. Conclusions: Despite a complex case mix, our adverse event and readmission rates are similar to the published literature describing a non-telemedicine model to deliver OPAT. High rates of favourable clinical outcomes and likely cost benefits suggest that telemedicine-supported OPAT is an efficacious and safe substitute for inpatient care in our setting.

Changing epidemiology of candidaemia in Australia.

Objectives: Knowledge of contemporary epidemiology of candidaemia is essential. We aimed to identify changes since 2004 in incidence, species epidemiology and antifungal susceptibilities of Candida spp. causing candidaemia in Australia. Methods: These data were collected from nationwide active laboratory-based surveillance for candidaemia over 1 year (within 2014-2015). Isolate identification was by MALDI-TOF MS supplemented by DNA sequencing. Antifungal susceptibility testing was performed using Sensititre YeastOne™. Results: A total of 527 candidaemia episodes (yielding 548 isolates) were evaluable. The mean annual incidence was 2.41/105 population. The median patient age was 63 years (56% of cases occurred in males). Of 498 isolates with confirmed species identity, Candida albicans was the most common (44.4%) followed by Candida glabrata complex (26.7%) and Candida parapsilosis complex (16.5%). Uncommon Candida species comprised 25 (5%) isolates. Overall, C. albicans (>99%) and C. parapsilosis (98.8%) were fluconazole susceptible. However, 16.7% (4 of 24) of Candida tropicalis were fluconazole- and voriconazole-resistant and were non-WT to posaconazole. Of C. glabrata isolates, 6.8% were resistant/non-WT to azoles; only one isolate was classed as resistant to caspofungin (MIC of 0.5 mg/L) by CLSI criteria, but was micafungin and anidulafungin susceptible. There was no azole/echinocandin co-resistance. Conclusions: We report an almost 1.7-fold proportional increase in C. glabrata candidaemia (26.7% versus 16% in 2004) in Australia. Antifungal resistance was generally uncommon, but azole resistance (16.7% of isolates) amongst C. tropicalis may be emerging.

Epidemiological, clinical, outcome and antibiotic susceptibility differences between PVL positive and PVL negative Staphylococcus aureus infections in Western Australia: a case control study.

BACKGROUND: Panton Valentine Leukocidin (PVL) has been associated with invasive Staphylococcus aureus soft tissue and pneumonic infections. METHODS: From September 2007 to January 2009 at Royal Perth Hospital we tested for the PVL gene in S. aureus isolates from an invasive site, a suspected PVL-related soft tissue infection and all MRSA isolates. We could access medical records for 141 PVL positive (PVL + ve) infections and compared these to a control group comprised of 148 PVL negative (PVL-ve) infections. RESULTS: In the PVL + ve group 62 isolates were MRSA (48 were ST93-MRSA-IV) and 79 isolates were methicillin-sensitive S. aureus, and in the PVL-ve group 56 were MRSA (50 were WA-MRSA strains) and 92 were methicillin-sensitive S. aureus. We found the presence of PVL to be significantly associated with younger age, aboriginality, intravenous drug use, community acquisition, shorter length of hospital stay and lower mortality at 1 year. Overall PVL + ve infections more often required surgical intervention (73.0% versus 44.6%, p < 0.001) and were less often polymicrobial (8.5% versus 41.2%, p < 0.001). PVL + ve isolates were more often susceptible to clindamycin (87.9% versus 73.0%, p = 0.002). CONCLUSIONS: This study demonstrates that PVL + ve infections are associated with a distinct clinical picture, predominantly pyogenic skin and soft tissue infections often requiring surgery, disproportionately affecting patients who are younger, indigenous or with fewer health-care risk factors.

Risk factors for nephrotoxicity in patients receiving outpatient continuous infusions of vancomycin in an Australian tertiary hospital.

OBJECTIVES: To assess the risk factors for nephrotoxicity caused by vancomycin continuous infusion in a predominantly Caucasian outpatient population. METHODS: This was a retrospective cohort study of 155 patient episodes from December 2006 to December 2011. RESULTS: Vancomycin-associated nephrotoxicity (VN) occurred in 26 of 155 (17%) patient episodes. After adjustment for baseline renal function, maximum steady-state vancomycin concentrations ≥32 mg/L [OR 8.7 (95% CI 3.1-29.6), P < 0.001] and angiotensin receptor blockade [OR 9.78 (95% CI 3.1-39.4), P < 0.001] were independently associated with VN. The cumulative dose and duration of vancomycin therapy were not independent predictors of VN. CONCLUSIONS: Cessation of angiotensin receptor-blocking medications in selected patient groups, enhanced monitoring and establishing target steady-state concentrations <30 mg/L to avoid excessive vancomycin exposure may reduce the risk of VN.

Cutaneous mucormycosis and motor vehicle accidents: Findings from an Australian case series.

Cutaneous disease is the third most frequent manifestation of mucormycosis. The clinical manifestations of and subsequent mortality due to cutaneous mucormycosis are dependent on the mode of acquisition and the host immune status. Here, we describe the epidemiology, clinical presentation, microbiology, and outcomes of 16 cutaneous mucormycosis infections managed in an Australian tertiary hospital over a 15-year period. The proportion with localized (56%), deep (38%), and disseminated (6%) cutaneous disease as well as the overall mortality (25%) were consistent with findings reported in the published literature. Two novel forms of hospital-acquired infection were reported following a sacral pressure sore and insertion of a foreign body during a bone graft procedure. The majority of patients were immunocompetent (75%) and/or suffered trauma (56%) with associated environmental contamination. A novel finding was that motor vehicle accidents (MVAs) accounted for 78% of all trauma-related cases, suggesting MVAs should receive greater recognition as a potential precipitant of cutaneous mucormycosis. Aggressive decontamination and debridement of devitalized tissue following trauma is therefore likely to play an important role in the prevention of this rare but potentially devastating infection.

Global guideline for the diagnosis and management of cryptococcosis: an initiative of the ECMM and ISHAM in cooperation with the ASM.

Cryptococcosis is a major worldwide disseminated invasive fungal infection. Cryptococcosis, particularly in its most lethal manifestation of cryptococcal meningitis, accounts for substantial mortality and morbidity. The breadth of the clinical cryptococcosis syndromes, the different patient types at-risk and affected, and the vastly disparate resource settings where clinicians practice pose a complex array of challenges. Expert contributors from diverse regions of the world have collated data, reviewed the evidence, and provided insightful guideline recommendations for health practitioners across the globe. This guideline offers updated practical guidance and implementable recommendations on the clinical approaches, screening, diagnosis, management, and follow-up care of a patient with cryptococcosis and serves as a comprehensive synthesis of current evidence on cryptococcosis. This Review seeks to facilitate optimal clinical decision making on cryptococcosis and addresses the myriad of clinical complications by incorporating data from historical and contemporary clinical trials. This guideline is grounded on a set of core management principles, while acknowledging the practical challenges of antifungal access and resource limitations faced by many clinicians and patients. More than 70 societies internationally have endorsed the content, structure, evidence, recommendation, and pragmatic wisdom of this global cryptococcosis guideline to inform clinicians about the past, present, and future of care for a patient with cryptococcosis.

Antifungal therapy and management of complications of cryptococcosis due to Cryptococcus gattii.

BACKGROUND: We describe antifungal therapy and management of complications due to Cryptococcus gattii infection in 86 Australian patients followed for at least 12 months. METHODS: Patient data from culture-confirmed cases (2000-2007) were recorded at diagnosis, 6 weeks, 6 months, and 12 months. Clinical, laboratory, and treatment variables associated with raised intracranial pressure (ICP) and immune reconstitution inflammatory syndrome (IRIS) were determined. RESULTS: Seven of 10 patients with lung infection received amphotericin B (AMB) induction therapy (6 with 5-flucytosine [5-FC] for a median of 2 weeks); median duration of therapy including azole eradication therapy was 41 weeks, with a complete/partial clinical response in 78%. For neurologic disease, 88% of patients received AMB, 78% with 5-FC, for a median of 6 weeks. The median total course was 18 months. Nine patients receiving fluconazole induction therapy were reinduced with AMB plus 5-FC for clinical failure. Raised ICP (31 patients) was associated with initial abnormal neurology, and neurologic sequelae and/or death at 12 months (both P = .02); cerebrospinal fluid drains/shunts were placed in 58% of patients and in 64% of 22 patients with hydrocephalus. IRIS developed 2-12 months after starting antifungals in 8 patients, who presented with new/enlarging brain lesions. Risk factors included female sex, brain involvement at presentation, and higher median CD4 counts (all P < .05); corticosteroids reduced cryptococcoma-associated edema. CONCLUSIONS: Induction AMB plus 5-FC is indicated for C. gattii neurologic cryptococcosis (6 weeks) and when localized to lung (2 weeks). Shunting was often required to control raised ICP. IRIS presents with cerebral manifestations.

The current state of laboratory mycology in Asia/Pacific: A survey from the European Confederation of Medical Mycology (ECMM) and International Society for Human and Animal Mycology (ISHAM).

INTRODUCTION: Invasive fungal infections (IFIs) in Asia/Pacific are a particular threat to patients with malignancies, uncontrolled diabetes mellitus or undiagnosed/untreated human immunodeficiency virus infection and acquired immunodeficiency syndrome (HIV/AIDS). Adequate and early access to diagnostic tools and antifungals is essential for IFI clinical management and patient survival. METHODS: Details on institution profile, self-perception on IFI, and access to microscopy, culture, serology, antigen detection, molecular testing, and therapeutic drug monitoring for IFI were collected in a survey. RESULTS: As of June 2022, 235 centres from 40 countries/territories in Asia/Pacific answered the questionnaire. More than half the centres were from six countries: India (25%), China (17%), Thailand (5%), Indonesia, Iran, and Japan (4% each). Candida spp. (93%) and Aspergillus spp. (75%) were considered the most relevant pathogens. Most institutions had access to microscopy (98%) or culture-based approaches (97%). Furthermore, 79% of centres had access to antigen detection, 66% to molecular assays, and 63% to antibody tests. Access to antifungals varied between countries/territories. At least one triazole was available in 93% of the reporting sites (voriconazole [89%] was the most common mould-active azole), whereas 80% had at least one amphotericin B formulation, and 72% had at least one echinocandin. CONCLUSION: According to the replies provided, the resources available for IFI diagnosis and management vary among Asia/Pacific countries/territories. Economical or geographical factors may play a key role in the incidence and clinical handling of this disease burden. Regional cooperation may be a good strategy to overcome shortcomings.

Invasive aspergillosis in adult patients in Australia and New Zealand: 2017-2020.

Background: New and emerging risks for invasive aspergillosis (IA) bring the need for contemporary analyses of the epidemiology and outcomes of IA, in order to improve clinical practice. Methods: The study was a retrospective, multicenter, cohort design of proven and probable IA in adults from 10 Australasian tertiary centres (January 2017-December 2020). Descriptive analyses were used to report patients' demographics, predisposing factors, mycological characteristics, diagnosis and management. Accelerated failure-time model was employed to determine factor(s) associated with 90-day all-cause mortality (ACM). Findings: Of 382 IA episodes, 221 (in 221 patients) fulfilled inclusion criteria - 53 proven and 168 probable IA. Median patient age was 61 years (IQR 51-69). Patients with haematologic malignancies (HM) comprised 49.8% of cases. Fifteen patients (6.8%) had no pre-specified immunosuppression and eleven patients (5.0%) had no documented comorbidity. Only 30% of patients had neutropenia. Of 170 isolates identified, 40 (23.5%) were identified as non-Aspergillus fumigatus species complex. Azole-resistance was present in 3/46 (6.5%) of A. fumigatus sensu stricto isolates. Ninety-day ACM was 30.3%. HM (HR 1.90; 95% CI 1.04-3.46, p = 0.036) and ICU admission (HR 4.89; 95% CI 2.93-8.17, p < 0.001) but not neutropenia (HR 1.45; 95% CI 0.88-2.39, p = 0.135) were associated with mortality. Chronic kidney disease was also a significant predictor of death in the HM subgroup (HR 3.94; 95% CI 1.15-13.44, p = 0.028). Interpretation: IA is identified in high number of patients with mild/no immunosuppression in our study. The relatively high proportion of non-A. fumigatus species complex isolates and 6.5% azole-resistance rate amongst A. fumigatus sensu stricto necessitates accurate species identification and susceptibility testing for optimal patient outcomes. Funding: This work is unfunded. All authors' financial disclosures are listed in detail at the end of the manuscript.

COVID-19 infection among patients with cancer in Australia from 2020 to 2022: a national multicentre cohort study.

Background: The global COVID-19 pandemic disproportionately affected certain populations and its management differed between countries. This national study describes characteristics and outcomes of COVID-19 in patients with cancer in Australia. Methods: We performed a multicentre cohort study of patients with cancer and COVID-19 from March 2020 to April 2022. Data were analysed to determine varying characteristics between cancer types and changes in outcomes over time. Multivariable analysis was performed to determine risk factors associated with oxygen requirement. Findings: 620 patients with cancer from 15 hospitals had confirmed COVID-19. There were 314/620 (50.6%) male patients, median age 63.5 years (IQR 50-72) and majority had solid organ tumours (392/620, 63.2%). The rate of COVID-19 vaccination (≥1 dose) was 73.4% (455/620). Time from symptom onset to diagnosis was median 1 day (IQR 0-3), patients with haematological malignancy had a longer duration of test positivity. Over the study period, there was a significant decline in COVID-19 severity. Risk factors associated with oxygen requirement included male sex (OR 2.34, 95% CI 1.30-4.20, p = 0.004), age (OR 1.03, 95% CI 1.01-1.06, p = 0.005); not receiving early outpatient therapy (OR 2.78, 95% CI 1.41-5.50, p = 0.003). Diagnosis during the omicron wave was associated with lower odds of oxygen requirement (OR 0.24, 95% CI 0.13-0.43, p < 0.0001). Interpretation: Outcomes from COVID-19 in patients with cancer in Australia over the pandemic have improved, potentially related to changing viral strain and outpatient therapies. Funding: This study was supported by research funding from MSD.

Clinical manifestations of Cryptococcus gattii infection: determinants of neurological sequelae and death.

BACKGROUND: Longer-term morbidity and outcomes of Cryptococcus gattii infection are not described. We analyzed clinical, microbiological, and outcome data in Australian patients followed for 12 months, to identify prognostic determinants. METHODS: Culture-confirmed C. gattii cases from 2000 to 2007 were retrospectively evaluated. Clinical, microbiological, radiological, and outcome data were recorded at diagnosis and at 6 weeks, 6 months, and 12 months. Clinical and laboratory variables associated with mortality and with death and/or neurological sequelae were determined. RESULTS: Annual C. gattii infection incidence was 0.61 per 10(6) population. Sixty-two of 86 (72%) patients had no immunocompromise; 6 of 24 immunocompromised hosts had idiopathic CD4 lymphopenia, and 1 had human immunodeficiency virus/AIDS. Clinical and microbiological characteristics of infection were similar in immunocompromised and healthy hosts. Isolated lung, combined lung and central nervous system (CNS), and CNS only disease was reported in 12%, 51% and 34% of the cases, respectively. Complications in CNS disease included raised intracranial pressure (42%), hydrocephalus (30%), neurological deficits (27%; 6% developed during therapy) and immune reconstitutionlike syndrome (11%). Geometric mean serum cryptococcal antigen (CRAG) titers in CNS disease were 563.9 (vs 149.3 in isolated lung infection). Patient immunocompromise was associated with increased mortality risk. An initial cerebrospinal fluid CRAG titer of ≥256 predicted death and/or neurological sequelae (P = .05). CONCLUSIONS: Neurological C. gattii disease predominates in the Australian endemic setting. Lumbar puncture and cerebral imaging, especially if serum CRAG titers are ≥512, are essential. Long-term follow up is required to detect late neurological complications. Immune system evaluation is important because host immunocompromise is associated with reduced survival.

Hospital costs, length of stay and mortality attributable to invasive scedosporiosis in haematology patients.

BACKGROUND: Scedosporium species are increasingly recognized as a cause of invasive mould disease in haematology patients, but little is known about the hospitalization costs and outcomes attributable to invasive scedosporiosis (SCEDO). METHODS: A retrospective case-control study was undertaken during 2002-10 to determine the attributable inpatient costs, length of stay (LOS) and mortality associated with SCEDO in haematology patients. Case patients with SCEDO (n = 30) were matched 1 : 2 to controls (n = 60) according to haematological diagnosis, admission year and age. Diagnostics, antifungal drugs, ward and other SCEDO-related costs were estimated using actual cost data. Median regression modelling was used to adjust for variables that were not accounted for in the matched-pairs analysis. RESULTS: The crude total median cost of treating SCEDO was AU$32 182 per patient versus AU$17 424 per control. In multivariable analysis, SCEDO was associated with median excess costs of AU$23 611 (95% CI = AU$17 992-AU$29 231; P < 0.001), approximating US$15 509 at purchasing power parity, with prolonged LOS of 13 days (95% CI = 8.2-17.8 days; P < 0.001). Exclusion of cases and matched pairs with early death further increased the median excess cost and LOS. The cost differential was driven by ward costs (64%, P = 0.005) and antifungal treatment costs (29%, P < 0.001). The all-cause inpatient mortality was 38 times higher for the SCEDO cases versus the control group (63.3% versus 1.7%; P < 0.001). CONCLUSIONS: SCEDO has substantial impact on hospital resource consumption, LOS and mortality in haematology patients. Risk factors and preventative measures for SCEDO should be further studied.
