Details
Understanding how juvenile idiopathic arthritis (JIA), the most common chronic inflammatory musculoskeletal disease in children and young people, impacts on adult-life has been prioritised by individuals living with JIA and their families, European arthritis organisations, and national charities. Currently, the lack of information on what happens to children with JIA as they become adults is a huge source of anxiety for young people and their families.
The aim of this PhD is to investigate the impact of JIA on adult-life with respect to healthcare utilisation, pregnancy, orthopaedic interventions, and infection. This PhD will use data from an existing UK inception cohort of JIA, linked with NHS England datasets to:
i. Understand healthcare utilisation of people living with JIA.
ii. Describe pregnancy outcomes in people living with JIA.
iii. Calculate the proportion of people with JIA experiencing orthopaedic interventions.
iv. Calculate the rates of hospitalised infections in people diagnosed with JIA.
These research questions will use multiple datasets. The Childhood Arthritis Prospective Study (CAPS) is a large UK inception cohort of children and young people with JIA from initial paediatric rheumatology appointment, linked with NHS England datasets; HES Outpatient, Admitted Patient Care, Accident and Emergency, and Critical Care data, as well as the Maternity Services Dataset (MSDS), and Mental Health Services Dataset (MHSDS). There are ~1300 individuals in this linked dataset, with valuable information from initial paediatric rheumatology appointment. In addition, the Clinical Practice Research Datalink (CPRD) of UK primary care records is available for a cohort of individuals with JIA, also linked to HES Outpatient and Admitted Patient Care, the Mother Baby Link and Pregnancy Register.
