Highlights from the 2022 Annual SHOT Report: lessons learnt and learning from excellence

This presentation will cover a case study completed as part of the IBMS Specialist Diploma in Immunology in 2022. It will be of interest to anyone considering completing the Higher Specialist Diploma in Immunology, or anyone who would like to learn more about the case study element. It will also be of interest to anyone who would like to learn more about the protocols used for reading and reporting methods including immunophenotyping by flow cytometry, serum protein electrophoresis and immunotyping, serum free light chains and Bence Jones protein analysis at Greater Manchester Immunology Service (GMIS).

The case is one of an elderly gentleman with who, like roughly a third of new myeloma cases in the UK, presented through A&E. The presentation will cover pre-analysis, analysis and post-analysis, considering how the tests performed in the Immunology laboratory assist in the differential diagnosis and where they fit in with the other tests ordered, both tests within and outside of the Immunology discipline. The presentation will cover the methods performed at GMIS and some of the reporting protocols, as well as discussing some of the relevant associated guidelines.

Antimicrobial resistance is a major concern with mortality rates growing exponentially. Current ASTs used clinically can take 24-48hrs to report results, ensuing in initial treatment with broad spectrum antibiotics. The novel iFAST method can report results within 2 hours of exposure to an antibiotic. The main objective of this study was to measure the impedance signal of resistant and sensitive isolates of Staphylococcus aureus that had been exposed to cefoxitin. Sequentially collected bacterial isolates were accessed from the clinical microbiology laboratory to determine susceptibility.

50 methicillin resistant/sensitive isolates of S. aureus were taken from the middle of the clinical workflow and tested on the iFAST. The isolates were streaked onto blood plates and incubated at 37 degrees for 2 hours. The bacteria were then exposed to cefoxitin for 2 hours at the EUCAST breakpoint concentration of 8mg/L. Following exposure, the samples were measured on the iFAST.

The impedance cytometer measures the electrical signal of bacterial cells as they individually flow through a microfluidic channel, via electrodes driven by an AC current of multiple frequencies. This is interpreted as a read-out of cell volume and opacity. Exposure to antibiotics can change the electrical characteristics of the bacterial cell in size and opacity compared to the control sample. The number of exposed cells within the contour defined by the control sample can measure how the cells have altered in opacity and size following exposure.

iFAST results showed 100% concordance with disk diffusion sensitivity testing carried out by the clinical laboratory. The data showed different electrical impedance changes for both resistant and sensitive strains of S. aureus. Sensitive strains showed a decrease in cell size and resistant strains showed an increase in cell size following exposure to cefoxitin.

The bacterial impedance cytometer was able to rapidly differentiate between MRSA and MSSA isolates in concordance with current susceptibility testing in the clinical setting. The results help to show how the iFAST could reduce the time taken to provide critical and accurate antibiotic treatment to patients.

Reporting haemovigilance incidents is vital to the ongoing learning from errors and improvements of quality management systems in transfusion. It is a statutory reguirement of the Blood Safety and Quality Regulations (2005) (as amended) and the data collected is used by both MHRA and SHOT to analyse and demonstrate key learning opportunities.

This presentation will give an overview of the legal requirements of the BSQR and the Good Practice Guide. Common isnspection findings will be presented and practical learning from SABRE reports will be shown. Common issues associated from reports received will be discussed and tips given as to how to improve the reporting of haemovigilance data.

This session provides an overview of the key changes to the ISO 15189 standard and explains the UKAS transition process including deadlines and actions to be taken by accredited organisations.

The same session is being run on Monday, Tuesday and Thursday to ensure as many delegates as possible are able to attend.

Following on from a talk given last year on the Precision AMR Project, this presentation will look at the incorporation of WGS and genotypic methods vs phenotypic methods and how they can impact on diagnostic laboratory practices, antibiotic reporting and prescribing.

This presentation follows on from the research on the Precision AMR project and discusses how this can be translated into routine practice. Also looking at potential new workflows that may be incorporated into laboratory's to support clinicians and infection control.
