BackgroundDelirium is a common severe neuropsychiatric condition secondary to physical illness, which predominantly affects older adults in hospital. Prior to this study, the UK point prevalence of delirium was unknown. We set out to ascertain the point prevalence of delirium across UK hospitals and how this relates to adverse outcomes.MethodsWe conducted a prospective observational study across 45 UK acute care hospitals. Older adults aged 65 years and older were screened and assessed for evidence of delirium on World Delirium Awareness Day (14th March 2018). We included patients admitted within the previous 48 h, excluding critical care admissions.ResultsThe point prevalence of Diagnostic and Statistical Manual on Mental Disorders, Fifth Edition (DSM-5) delirium diagnosis was 14.7% (222/1507). Delirium presence was associated with higher Clinical Frailty Scale (CFS): CFS 4–6 (frail) (OR 4.80, CI 2.63–8.74), 7–9 (very frail) (OR 9.33, CI 4.79–18.17), compared to 1–3 (fit). However, higher CFS was associated with reduced delirium recognition (7–9 compared to 1–3; OR 0.16, CI 0.04–0.77). In multivariable analyses, delirium was associated with increased length of stay (+ 3.45 days, CI 1.75–5.07) and increased mortality (OR 2.43, CI 1.44–4.09) at 1 month. Screening for delirium was associated with an increased chance of recognition (OR 5.47, CI 2.67–11.21).ConclusionsDelirium is prevalent in older adults in UK hospitals but remains under-recognised. Frailty is strongly associated with the development of delirium, but delirium is less likely to be recognised in frail patients. The presence of delirium is associated with increased mortality and length of stay at one month. A national programme to increase screening has the potential to improve recognition.

Future trials of FMT will likely revisit Crohn's disease and patients undergoing pouch surgery. Advances in microbial culture complementing genetic sequencing and investigations into the virome and mycobiome in IBD will be of great future interest.

Background: In real-world clinical practice, biologics in inflammatory bowel diseases (IBD) may be discontinued for a variety of reasons, including discontinuation initiated by gastroenterologists. The aims of the study are to report outcomes after discontinuation and predictors of prognosis after a minimum follow-up of 24 months; outcomes of gastroenterologist-initiated discontinuation with resulting direct cost implications on the health system were also studied. Methods: IBD patients who discontinued their first-use biologics between January 2013 and December 2016 were identified at our tertiary centre. Reasons for discontinuation and pre-defined adverse outcomes (AO) were recorded. Data were analysed using univariable and multivariable logistic regressions within a machine learning technique to predict AO. Gastroenterologist-initiated discontinuations were analysed separately, and Kaplan–Meier survival analysis performed; direct costs of AO due to discontinuation were assessed. Results: A total of 147 patients discontinued biologics (M = 74; median age 39 years; Crohn’s Disease = 110) with median follow-up of 40 months (range 24–60 months). In the total cohort, there were fewer AO among gastroenterologist-initiated discontinuations compared with patient-initiated; 54% (of the total group) had AO within 6 months. Among 59 gastroenterologist-initiated discontinuations, 23 (40%) had IBD-related AO within 6 months and 53 (90%) patients had AO by end of follow-up. Some 44 (75%) patients needed to restart biologics during follow-up, and direct costs due to AO and restart of biologics were high. Conclusions: The proportion of patients who have AO following discontinuation of biologics is high; clinicians need to carefully consider predictors of poor prognosis and high relapse rates when discussing discontinuation. The direct costs of managing AO probably offset theoretical economic gains, especially in the era where cost of biologics is reducing. Biologics should probably be continued without interruptions in most patients who have achieved remission for the duration these remain effective and safe.

Background Strictures related to Crohn’s disease due to fibrosis are a result of an exaggerated tissue remodelling response to inflammation, characterized by accumulation of collagen-rich extracellular matrix produced by mesenchymal cells. Objectives The objective of this study was to characterize histological changes seen in resected ‘fibrotic’ strictures to better understand individual components of intestinal stenosis. Methods We identified patients undergoing surgery for ileal Crohn’s disease secondary to symptomatic stricturing disease (Montreal B2) using the histopathology database at Queen Elizabeth Hospital in Birmingham, UK, between 2012 and 2017. Phenotypic data were recorded and resection specimens reviewed. Two independent pathologists applied the semiquantitative scoring system previously developed by us to the microscopic images. Data were analyzed using the possible maximum total score (%PMTS). Results Forty-eight patients (M = 25) were included. with median disease duration of 7 years (range 0.25–39 years); nearly two-thirds had ileocolonic distribution (L3). In this cohort, despite presurgery diagnosis of noninflamed fibrosis, chronic inflammation was noted to be a prominent component of all strictures. The histological scoring showed presence of several other prominent findings such as muscular hyperplasia and volume expansion.There was statistically significant positive correlation between chronic inflammation and fibrosis and muscular hyperplasia. Conclusion The histological features of Crohn’s disease-related strictures show multiple changes in multiple layers and not simply fibrosis. In our cohort, despite the observation prior to surgery that strictures were clinically considered fibrotic, the finding of chronic inflammation as a dominant component at a histological level in the resection is important. The findings might suggest that one of the main drivers of progressive fibrosis is the inflammatory component, which probably is never fully resolved.

IntroductionAtraumatic needles are associated with a decreased incidence of postdural-puncture headache. They also reduce the need for additional treatment and have similar efficacy to conventional needles. The aim of this Quality Improvement Project (QIP) was to encourage the use of atraumatic needles in Neurology ambulatory care by developing a sustainable Lumbar Puncture (LP) training method.MethodsA specialised atraumatic needle training video was guru.kumar@nhs.net created for junior doctors starting in Neurology. This accompanied further teaching and opportunities to practice LPs on a simulation mannequin under supervision. Atraumatic needles were added to standard stock and supply was ensured.Two audit cycles recorded the number of LPs performed using an atraumatic needle. Patient age, body mass index, length of stay, pain experienced and any need for image guidance were also recoded. Junior doctor confidence was measured before and after training.Results81 LPs were performed in the first cycle, 83 in the second. Atraumatic needle use increased from 26% to 50% between cycles. Junior doctor confidence increased with training from 2/10 to 8/10 (p=0.02).ConclusionsDedicated induction teaching and observed simulation practice increased junior doctors’ confidence in, and frequency of, the use of atraumatic needles.
