Declarations

:

: All data used for this study was pseudonymised prior to its use. The study, as part of the Infections in Oxfordshire Research Database (IORD), was approved by the National Research Ethics Service South Central – Oxford C Research Ethics Committee (19/SC/0403), the Health Research Authority and the national Confidentiality Advisory Group (19/CAG/0144), including provision for use of pseudonymised routinely collected data without individual patient consent. As such, individual patient consent was not obtained for the purposes of this study. Individuals who choose to opt out of their data being used in research are not included in the study. The study sponsor was OUH. All patients were assigned an anonymised ‘cluster ID’, with no identifying details handled by the research team. Only month/year of birth was available rather than specific date of birth. Data were held within a password protected, encrypted database and accessed only by named investigators in accordance with NHS standards for data management and protection.
