A service review of fibroscan at King’s College Hospital, opportunities for service improvement in non-hepatology specialities

P54 Figure 1ConclusionUnsurprisingly, there were 1.5 times more fibroscan cases in the pre-covid year (1633 in 2019 compared to 1058 in 2021), indicating the negative impact of COVID-19 in the diagnosis of chronic liver diseases. In addition, NAFLD had a higher rate of advanced fibrosis compared to hepatitis B with the possibility of more sequential HBV follow-up, late referral of NAFLD or impact of fasting state on steatohepatitis.We need to evaluate the interval and indications of repeat fibroscan in each etiology due to no significant variation of LSM value despite different fibroscan intervals. We also need to improve the fibroscan access in district hospitals and other specialities regarding external referral data.

Treating children with HCV close to home through a virtual national multidisciplinary network

Background and AimsHepatitis C virus (HCV) infection is a major global health problem in adults & children. The recent efficacy of Direct Acting Anti-viral therapy (DAA) has cure rates of 99% in adults and adolescents. These drugs were licensed for children 3–12 yrs during the recent coronavirus pandemic. To ensure equitable access, safe & convenient supply during lockdown, we established a virtual national treatment pathway for children with HCV in England & evaluated its feasibility, efficacy & treatment outcomes.MethodA paediatric Multidisciplinary Team Operational Delivery Network (pMDT ODN), supported by NHS England (NHSE), was established with relevant paediatric specialists to provide a single point of contact for referrals & information. Referral & treatment protocols were agreed for HCV therapy approved by MHRA & EMA. On referral the pMDT ODN agreed the most appropriate DAA therapy based on clinical presentation & patient preferences, including ability to swallow tablets. Treatment was prescribed in association with the local paediatrician & pharmacist, without the need for children & families to travel to national centres. All children were eligible for NHS funded therapy;referral centres were approved by the pMDT ODN to dispense medication;funding was reimbursed via a national NHSE agreement. Demographic & clinical data, treatment outcomes & SVR 12 were collected. Feedback on feasibility & satisfaction on the pathway was sought from referrers.ResultsIn the first 6 months, 34 children were referred;30- England;4 - Wales;median (range) age 10 (3.9 – 14.5) yrs;15M;19F: Most were genotype type 1 (17) & 3 (12);2 (1);4(4). Co-morbidities included: obesity (2);cardiac anomaly (1);Cystic Fibrosis (1);Juvenile Arthritis (1). No child had cirrhosis. DAA therapy prescribed: Harvoni (21);Epclusa (11);Maviret (2) .27/34 could swallow tablets;3/7 received training to swallow tablets;4/7 are awaiting release of granules.11/27 have completed treatment and cleared virus;of these 7/11 to date achieved SVR 12. 30 children requiring DAA granule formulation are awaiting referral and treatment.Referrers found the virtual process easy to access, valuing opportunity to discuss their patient’s therapy with the MDT & many found it educational. There were difficulties in providing the medication through the local pharmacy. However there are manufacturing delays in providing granule formulations because suppliers focused on treatments for COVID, leading to delays in referring and treating children unable to swallow tablets.ConclusionThe National HCV pMDT ODN delivers high quality treatment & equity of access for children & young people, 3– 18 yrs with HCV in England, ensuring they receive care close to home with 100% cure rates.

A clinical risk score to identify patients with COVID-19 at high risk of critical care admission or death: An observational cohort study.

BACKGROUND: The COVID-19 pandemic continues to escalate. There is urgent need to stratify patients. Understanding risk of deterioration will assist in admission and discharge decisions, and help selection for clinical studies to indicate where risk of therapy-related complications is justified. METHODS: An observational cohort of patients acutely admitted to two London hospitals with COVID-19 and positive SARS-CoV-2 swab results was assessed. Demographic details, clinical data, comorbidities, blood parameters and chest radiograph severity scores were collected from electronic health records. Endpoints assessed were critical care admission and death. A risk score was developed to predict outcomes. FINDINGS: Analyses included 1,157 patients. Older age, male sex, comorbidities, respiratory rate, oxygenation, radiographic severity, higher neutrophils, higher CRP and lower albumin at presentation predicted critical care admission and mortality. Non-white ethnicity predicted critical care admission but not death. Social deprivation was not predictive of outcome. A risk score was developed incorporating twelve characteristics: age>40, male, non-white ethnicity, oxygen saturations<93%, radiological severity score>3, neutrophil count>8.0 x109/L, CRP>40 mg/L, albumin<34 g/L, creatinine>100 µmol/L, diabetes mellitus, hypertension and chronic lung disease. Risk scores of 4 or higher corresponded to a 28-day cumulative incidence of critical care admission or death of 40.7% (95% CI: 37.1 to 44.4), versus 12.4% (95% CI: 8.2 to 16.7) for scores less than 4. INTERPRETATION: Our study identified predictors of critical care admission and death in people admitted to hospital with COVID-19. These predictors were incorporated into a risk score that will inform clinical care and stratify patients for clinical trials.
