RESUMEN
Candida auris, an emerging fungus that can cause invasive infections, is associated with high mortality and is often resistant to multiple antifungal drugs. C. auris was first described in 2009 after being isolated from external ear canal discharge of a patient in Japan (1). Since then, reports of C. auris infections, including bloodstream infections, have been published from several countries, including Colombia, India, Israel, Kenya, Kuwait, Pakistan, South Africa, South Korea, Venezuela, and the United Kingdom (2-7). To determine whether C. auris is present in the United States and to prepare for the possibility of transmission, CDC issued a clinical alert in June 2016 informing clinicians, laboratorians, infection control practitioners, and public health authorities about C. auris and requesting that C. auris cases be reported to state and local health departments and CDC (8). This report describes the first seven U.S. cases of C. auris infection reported to CDC as of August 31, 2016. Data from these cases suggest that transmission of C. auris might have occurred in U.S. health care facilities and demonstrate the need for attention to infection control measures to control the spread of this pathogen.

Introduction: Individuals living with sickle cell disease experience high levels of morbidity that result in frequent utilization of the emergency department. The objective of this study was to provide updated national estimates of emergency department utilization associated with sickle cell disease in the U.S. Methods: Data from the National Hospital Ambulatory Medical Care Survey for the years 1999-2020 were analyzed. Complex survey analysis was utilized to produce national estimates overall and by patient age groups. Results: On average, approximately 222,612 emergency department visits occurred annually among individuals with sickle cell disease, a nearly 13% increase from prior estimates. The annual volume of emergency department visits steadily increased over time, and pain remains the most common patient-cited reason for visiting the emergency department. Patient-reported pain levels for individuals with sickle cell disease were high, with 64% of visits associated with severe pain and 21% associated with moderate pain. Public insurance sources continue to cover most visits, with Medicaid paying for 60% of visits and Medicare paying for 12% of visits. The average time spent in the emergency department increased from previous estimates by about an hour, rising to approximately 6 hours. The average wait time to see a provider was 53 minutes. Conclusions: Utilization of the emergency department by individuals living with sickle cell disease remains high, especially for pain. With more than half of patients with sickle cell disease reporting severe pain levels, emergency department staff should be prepared to assess and treat sickle cell disease-related pain following evidence-based guidelines and recommendations. The findings of this study can help improve care in this population.

BACKGROUND: Commercially available prolactin immunoassays detect macroprolactin to variable degrees. Best practice requires laboratories to assess the cross-reactivity of their prolactin assay with macroprolactin, and where appropriate, introduce a screen for the presence of macroprolactin. Our policy has been to reanalyse hyperprolactinaemic samples following polyethylene glycol (PEG) precipitation and to report the resultant value as the monomeric prolactin content of the sample. The goal of this study was to determine the need to continue PEG precipitation when prolactin measurements with the Wallac AutoDELFIA were replaced by the Beckman DxI 800. METHODS: A total of 317 apparently hyperprolactinaemic samples were analysed for prolactin using the Beckman DxI 800 and results compared with those determined with the PEG screening technique on the Wallac AutoDELFIA. Any samples demonstrating a discordance of >25% were re-analysed using gel filtration chromatography (GFC) for a definitive result. RESULTS: The results indicate the Beckman DxI overestimates the prolactin concentration in 1%-2% of hyperprolactinaemic samples. PEG precipitation prior to analysis with the Wallac AutoDELFIA resulted in a 1% false negative diagnosis of hyperprolactinaemia. CONCLUSIONS: Prolactin results can be reported directly from the DxI. When results are discordant with the clinical presentation, prolactin should be measured using GFC.

Collaboration among diverse stakeholders involved in the value transformation of health care requires consistent use of terminology. The objective of this study was to reach consensus definitions for the terms value-based care, value-based payment, and population health. A modified Delphi process was conducted from February 2017 to July 2017. An in-person panel meeting was followed by 3 rounds of surveys. Panelists anonymously rated individual components of definitions and full definitions on a 9-point Likert scale. Definitions were modified in an iterative process based on results of each survey round. Participants were a panel of 18 national leaders representing population health, health care delivery, academic medicine, payers, patient advocacy, and health care foundations. Main measures were survey ratings of definition components and definitions. At the conclusion of round 3, consensus was reached on the following definition for value-based payment, with 13 of 18 panelists (72.2%) assigning a high rating (7- 9) and 1 of 18 (5.6%) assigning a low rating (1-3): "Value-based payment aligns reimbursement with achievement of value-based care (health outcomes/cost) in a defined population with providers held accountable for achieving financial goals and health outcomes. Value-based payment encourages optimal care delivery, including coordination across healthcare disciplines and between the health care system and community resources, to improve health outcomes, for both individuals and populations." The iterative process elucidated specific areas of agreement and disagreement for value-based care and population health but did not reach consensus. Policy makers cannot assume uniform interpretation of other concepts underlying health care reform efforts.

BACKGROUND: Transmission of multidrug-resistant Candida auris infection has been reported in the USA. To better understand its emergence and transmission dynamics and to guide clinical and public health responses, we did a molecular epidemiological investigation of C auris cases in the USA. METHODS: In this molecular epidemiological survey, we used whole-genome sequencing to assess the genetic similarity between isolates collected from patients in ten US states (California, Connecticut, Florida, Illinois, Indiana, Maryland, Massachusetts, New Jersey, New York, and Oklahoma) and those identified in several other countries (Colombia, India, Japan, Pakistan, South Africa, South Korea, and Venezuela). We worked with state health departments, who provided us with isolates for sequencing. These isolates of C auris were collected during the normal course of clinical care (clinical cases) or as part of contact investigations or point prevalence surveys (screening cases). We integrated data from standardised case report forms and contact investigations, including travel history and epidemiological links (ie, patients that had shared a room or ward with a patient with C auris). Genetic diversity of C auris within a patient, a facility, and a state were evaluated by pairwise differences in single-nucleotide polymorphisms (SNPs). FINDINGS: From May 11, 2013, to Aug 31, 2017, isolates that corresponded to 133 cases (73 clinical cases and 60 screening cases) were collected. Of 73 clinical cases, 66 (90%) cases involved isolates related to south Asian isolates, five (7%) cases were related to South American isolates, one (1%) case to African isolates, and one (1%) case to east Asian isolates. Most (60 [82%]) clinical cases were identified in New York and New Jersey; these isolates, although related to south Asian isolates, were genetically distinct. Genomic data corroborated five (7%) clinical cases in which patients probably acquired C auris through health-care exposures abroad. Among clinical and screening cases, the genetic diversity of C auris isolates within a person was similar to that within a facility during an outbreak (median SNP difference three SNPs, range 0-12). INTERPRETATION: Isolates of C auris in the USA were genetically related to those from four global regions, suggesting that C auris was introduced into the USA several times. The five travel-related cases are examples of how introductions can occur. Genetic diversity among isolates from the same patients, health-care facilities, and states indicates that there is local and ongoing transmission. FUNDING: US Centers for Disease Control and Prevention.

BACKGROUND: Decades of hospital restructuring in Canada resulted in significant reductions of nursing leadership positions and altered a nursing infrastructure important for guiding patient care. The importance of acquiring nursing leadership skills to address the negative effects of restructuring is advocated by Canadian nursing bodies. OBJECTIVES: To describe a service innovation for a nursing community. The librarians of the University of Manitoba Health Sciences Libraries (UMHSL) created an online nursing leadership literature centre to support a leadership programme launched by the Nursing Leadership Council (NLC) of the Winnipeg Regional Health Authority. The article will contribute to the body of literature about health library services for nurses. METHODS: The creation of the service is described. A literature search was undertaken to determine what services have been implemented by librarians for nursing leadership programmes, as well as to review the literature with regard to contributions made by librarians for nursing communities. RESULTS: The literature service, comprised of 19 webliographies based on the NLC's leadership topics, is available on the UMHSL website. A webliography, by definition, is a list of electronic works relating to a particular topic. The NLC created its own website that provides nurses with a means to identify, enhance and evaluate leadership competencies, and which is linked to the UMHSL website. CONCLUSION: The contributions of the UMHSL librarians to this project support the goals of instilling leadership skills in nurses, encouraging evidence-based nursing practice, and transforming a practice environment to meet the ultimate goal of effective patient care.
