Candida auris outbreak: Mortality, interventions and cost of sustaining control.

OBJECTIVE: Candida auris has recently emerged as a global cause of multidrug resistant fungal outbreaks. An outbreak occurred at a tertiary care center in London in 2016. Transmission characteristics, interventions, patient outcomes and cost of resources are described. METHODS: Outbreak interventions included patient isolation, contact screening, single-use equipment, environmental screening and decontamination, staff education, and enhanced surveillance. Risk factors for infection were recorded. Survival probabilities of patients with C. auris and other Candida bloodstream infections (BSI) were calculated. Antifungal susceptibility and epidemiological typing were performed. Actual and opportunity costs of interventions were determined. RESULTS: 34 patients acquired the organism including 8 with BSI. Clinical infection was significantly associated with prolonged hospital stay, haemodialysis and antifungal therapy. Variable susceptibility to amphotericin and the triazoles was seen and isolates clustered with the South Asian strains. No significant difference was detected in the survival probabilities of C. auris BSI compared to other candidemias. Outbreak control cost in excess of £1 million and £58,000/month during the subsequent year. CONCLUSION: C. auris outbreaks can be controlled by a concerted infection control strategy but can be expensive. Transmission maybe prolonged due to patient movements and unidentified transmission mechanisms.

Multiplex PCR point of care testing versus routine, laboratory-based testing in the treatment of adults with respiratory tract infections: a quasi-randomised study assessing impact on length of stay and antimicrobial use.

BACKGROUND: Laboratory-based respiratory pathogen (RP) results are often available too late to influence clinical decisions such as hospitalisation or antibiotic treatment due to time delay in transport of specimens and testing schedules. Ward-based i.e. point of care (POC) testing providing rapid results may alter the clinical management pathway. METHODS: FilmArray® RP polymerase chain reaction (PCR) systems were placed in three in-patient and out-patient medical areas. Patients presenting with influenza-like illness /upper respiratory tract infection +/- lower RTI were recruited between January-July 2015. FilmArray® POC testing occurred on even days of the month (intervention) or routine, laboratory-based RP PCR testing +/- atypical serology on odd days (control). The primary outcome was length of hospital stay. The secondary outcomes were impact on the use of antimicrobials, readmissions, all-cause mortality, length of ward stay and turn-around time (TAT) (time to result from admission). RESULTS: Of 606 eligible patients, 545 (89.9%) were included; 211 in the control arm and 334 in the intervention arm. 20% of control arm patients and 24% of intervention arm patients had an RP detected. POC testing was not associated with the primary outcome measure, length of stay, but reduced the TAT from 39.5 h to 19.0 h, p < 0.001. Only the prescribing decision differed between study arms, p < 0.001. When antivirals were given, the intervention was associated with a reduction in the median time to the first dose of 36 h and allowed appropriate treatment of mycoplasma infection. CONCLUSIONS: We found no association between respiratory PCR POC testing and length of stay or most of the secondary outcomes except the antimicrobial prescribing decision. This was probably due to a delay in initiating FilmArray® testing. Despite this, POC testing allowed time-critical antivirals to be given significantly faster, appropriate mycoplasma treatment and results were available considerably faster than routine, laboratory-based testing. Ward-staff of all grades performed POC testing without difficulty suggesting potential use across many divergent healthcare settings. Further studies evaluating the implementation of rapid respiratory PCR POC testing and the effect on length of stay and antimicrobial use are required.

Patients assessing students' assignments; making the patient experience real.

The care of patients with inflammatory bowel disease (IBD) frequently falls short of the highest standards. This is noted in several publications, including national standards, despite nursing students being taught the importance of listening to and understanding patients. Teaching staff at the University of Glasgow primarily responsible for teaching third year undergraduate nursing students undertook a radical rethink of the planning, delivery and assessment of lectures on IBD. The subject had previously been delivered in a modified lecture format. Although the topic could be included in the end-of-year exams, there was little evidence to show whether this traditional teaching method had any effect on students' clinical practice. In a novel approach to learning and assessment, students were invited to research and produce an information leaflet for newly diagnosed patients with IBD. The leaflets were then assessed and grades awarded by an expert panel of patients and carers. Such enquiry based learning (EBL) intended to demonstrate in practice, the key role patients can play in both undergraduate nurse education and in service planning and delivery in the National Health Service (NHS). The panel found the exercise both interesting and insightful, while the students reported being invigorated and felt the expert assessment meant they were forced to achieve a higher level of work.
