UK Paediatric Allergy Services Survey

posted on 2022-07-28, 09:43 authored by Michael PerkinMichael Perkin

National Survey of United Kingdom Paediatric Allergy Services

The  survey was completed in two stages. In the first stage, the contact  details of all 450 hospitals in the UK were found from online searches. Each hospital was contacted to establish whether the hospital provides a paediatric allergy service. If a paediatric allergy service is provided, the respondent was asked for the contact details of the person best placed to answer more detailed questions about the service. The 450 hospitals are part of 173 trusts. All 450 hospitals responded and  229 reported providing a paediatric allergy service. Some trusts provide paediatric allergy services in more than one hospital. The lead hospital was identified, resulting in 154 hospitals where the paediatric allergy service is principally provided (lead service) and 75 other  hospitals where the service provided is linked to the provision in a lead hospital service (linked service). A detailed questionnaire was then sent to the lead hospitals. A copy of the questionnaire is included with the data.

All 154 lead services seeing paediatric allergy patients nationally completed the survey between February 2019 and May 2020. The two last respondents completed their surveys after the start of the Covid-19  pandemic and were asked to record the configuration of their service  prior to any impact of the pandemic. Respondents were asked if they  provide a secondary or tertiary allergy service or both. The terms were  not further defined and interpretation was entirely at the discretion of  the respondent. Responses were: 126 (82%) secondary only and 3 (2%)  tertiary only and 25 (16%) secondary and tertiary level paediatric  allergy care. For subsequent analyses, tertiary only and secondary and  tertiary respondents were combined. Seventy one (46%) were providing  paediatric allergy services in one or more other hospitals.

The survey results were published in Clinical & Experimental Allergy and are available at
