Critical Care data - September 2020
The Critical Care data
The Critical Care data is part of the hospital inpatient data in Category 2000 and consists an additional table, HESIN_CRITICAL, on the Data Portal which links to hospital inpatient episodes on the main HESIN table. The data contains information on any stays in critical care units in England by UK Biobank participants.
It consists of the following:
The source of admission; where the patient was transferred into critical care from, such as from within the same hospital or from another NHS hospital.
Dates of admission to, and discharge from, critical care; including whether the patient survived or died. (We are also aiming to add times of admission and discharge, or some approximation to these, to the data in the next few months, but these will not be available in this initial release.)
Details of the type of support provided and the number of days that the support was received. Types of support comprise: respiratory, cardiovascular, gastrointestinal, dermatological, liver and renal. For respiratory and cardiovascular support further information is provided on whether basic or advanced support was given.
The maximum number of organs which were supported at any one time.
The number of days during which level 2 or level 3 care was provided. Level 2 care is defined as either provision of support for a single failing organ system, or those requiring post-operative care, or those stepping down from higher levels of care. Level 3 care is defined as either provision of support for those requiring advanced respiratory support alone, or monitoring and support for two or more organ systems.
The Critical Care data mainly covers admissions from April 2011 onwards, but there are a small number of records prior to that date (as far back as 2008).
Further information can be found in the Inpatient Data Dictionary, Resource 141140, in Category 2000. The NHS Digital HES Data Dictionary page also provides additional information.
At present the data is only available for England, but in due course we hope to have comparable data for Wales and Scotland.
Accessing the Critical Care data
Those researchers who have requested COVID-19 hospital data on AMS (i.e. by pressing the "COVID-19" button on their project and selecting "Hospitalisation data" from the options) will automatically gain access to the HESIN_CRITICAL table.
Other researchers who are not undertaking COVID-19 research but who would like access to the HESIN_CRITICAL table can do so by submitting a request for additional data through Showcase in the usual way. Adding Field 41290 (Records in HES inpatient critical care dataset) to a basket will provide access to the table on the Data Portal.
