Title of paper: External validation of a prognostic model to improve prediction of psychosis in primary care

Available at: https://doi.org/10.3399/BJGP.2024.0017

This paper reports the external validation of the only psychosis risk prediction algorithm to be used in primary care. External validation of prediction algorithms is essential to provide evidence of transportability i.e. that the algorithm can be used outside its training environment. This vital step for prediction algorithms is often missed.

Today, we’re speaking to Dr Sophie Ansems, a GP and PhD candidate, and Dr Lianne Mulder, both based at the Department of Primary and Long-term Care at the University of Groningen in the Netherlands.

Title of paper: General practitioners’ perspectives on diagnostic testing in children with persistent non-specific symptoms

Available at: https://doi.org/10.3399/BJGP.2023.0683

It is known that GPs employ diagnostic tests in adults with persistent non-specific symptoms for motives beyond strictly diagnostic purposes, but comparable research has not been conducted in children. This study adds that although GPs want to limit unnecessary invasive procedures in children, non-diagnostic motives to test are considered important, for example to provide reassurance or secure the GP-patient relationship. The decision to conduct diagnostic tests in children with persistent non-specific symptoms is based on a complex trade-off among medical considerations, psychosocial factors, consultation management, and efficient resource utilization. Awareness amongst GPs of the motives underlying their own testing behaviour in children with PNS could prompt changes in their testing practices.

Today, we’re speaking to Dr Amy Clark and Dr Kathryn Hughes. Amy is a resident doctor in North West Anglia Foundation Trust, and Kathryn who is a GP and a Senior Clinical Lecturer based at PRIME Centre Wales within Cardiff University.

Title of paper: Assessing acutely ill children in general practice using the National PEWS and LqSOFA clinical scores: a retrospective cohort study

Available at: https://doi.org/10.3399/BJGP.2023.0638

The validity of the current NICE-recommended scoring system for identifying seriously ill children in general practice, the Traffic Light system, was recently investigated and shown to perform poorly. A new National PEWS (Paediatric Early Warning Score) has just been introduced in hospital settings with hopes for subsequent implementation in general practice, to improve the identification of seriously unwell children. To the authors’ knowledge, the score has not previously been validated in general practice. This study found that the National PEWS would not accurately identify children requiring hospital admission within two days of presenting to general practice with an acute illness and therefore should not be recommended for this purpose without adjustment. Another score, the Liverpool quick Sequential Organ Assessment (Lq-SOFA), was also investigated and found to perform poorly in general practice.
