The utility and safety of paediatric endoscopy in a district general hospital in Southeast England.

This study was done to evaluate the appropriateness, diagnostic yield, and quality of paediatric gastrointestinal endoscopy in a large DGH with tertiary paediatric gastroenterology services. It was a retrospective cohort study of children who had at least one gastrointestinal endoscopy during 31 months (May 2018-Dec 2020) in a district general hospital in Southeast England. The participants were children (2-17 years). Two hundred ninety-three procedures were performed in total, 80% were diagnostic and 20% for surveillance. The median age was 12 years and 52.5% were males. Oesophago-gastro-duodenoscopy (OGD) corresponded to 79.5% of procedures, ileo-colonoscopy (IC) to 7.2% and the remaining had both procedures. The main diagnostic indication was persistent abdominal pain in 33.5% of cases, followed by suspected GORD (14.8%), recurrent vomiting (14.3%), dysphagia (9.1%) and blood loss per rectum (8.6%). A total of 64.7% showed abnormal macroscopic findings, and 69.2% showed histopathological signs of disease. The most common histological diagnosis was gastritis in 23% followed by coeliac disease in 13%, reflux oesophagitis in 12.2% and inflammatory bowel disease in 9.6%. Procedures were performed with utmost safety with two reported cases of complications, which were appropriately managed. The completion rate of diagnostic IC was 87%. A waiting time of 6 weeks was achieved in 50.4% of cases. CONCLUSION: Paediatric endoscopy can be safely performed in a district general hospital with the right setup and can aid in the management of gastrointestinal disease in the paediatric patient. It is important to monitor and regularly audit such practices to improve the quality of specialist services. WHAT IS KNOWN: • Paediatric endoscopy is predominantly performed in large tertiary centres and included in the diagnostic algorithm for many paediatric gastrointestinal conditions. • There are recommendations on clinical indication endorsed by ESPGHAN and key quality indicators published jointly by JAG and BSPGHAN. WHAT IS NEW: • Paediatric endoscopy can be appropriately and safely performed in district general hospital by trained professionals, decreasing the workload in larger tertiary paediatric centres. • Adoption of regular audit practices is essential to ensure and improve quality and appropriateness of this specialist service.

Impact of meningococcal ACWY conjugate vaccines on pharyngeal carriage in adolescents: evidence for herd protection from the UK MenACWY programme.

OBJECTIVE: Serogroup W and Y invasive meningococcal disease increased globally from 2000 onwards. Responding to a rapid increase in serogroup W clonal complex 11 (W:cc11) invasive meningococcal disease, the UK replaced an adolescent booster dose of meningococcal C conjugate vaccine with quadrivalent MenACWY conjugate vaccine in 2015. By 2018, the vaccine coverage in the eligible school cohorts aged 14 to 19 years was 84%. We assessed the impact of the MenACWY vaccination programme on meningococcal carriage. METHODS: An observational study of culture-defined oropharyngeal meningococcal carriage prevalence before and after the start of the MenACWY vaccination programme in UK school students, aged 15 to 19 years, using two cross-sectional studies: 2014 to 2015 "UKMenCar4" and 2018 "Be on the TEAM" (ISRCTN75858406). RESULTS: A total of 10 625 participants preimplementation and 13 438 postimplementation were included. Carriage of genogroups C, W, and Y (combined) decreased from 2.03 to 0.71% (OR 0.34 [95% CI 0.27-0.44], p < 0.001). Carriage of genogroup B meningococci did not change (1.26% vs 1.23% [95% CI 0.77-1.22], p = 0.80) and genogroup C remained rare (n = 7/10 625 vs 17/13 438, p = 0.135). The proportion of serogroup positive isolates (i.e. those expressing capsule) decreased for genogroup W by 53.8% (95% CI -5.0 - 79.8, p = 0.016) and for genogroup Y by 30.1% (95% CI 8.946·3, p = 0.0025). DISCUSSION: The UK MenACWY vaccination programme reduced carriage acquisition of genogroup and serogroup Y and W meningococci and sustained low levels of genogroup C carriage. These data support the use of quadrivalent MenACWY conjugate vaccine for indirect (herd) protection.
