Coronavirus (COVID-19) datasets

 

GPES data for pandemic planning and research (GDPPR) - To support the response to the coronavirus outbreak, NHS Digital has been asked to establish a central collection of GP patient data for COVID-19 purposes for the duration of the coronavirus emergency period.

To apply for access to this data, you should first fill in the Access Request Form for GPES Data for Pandemic Planning and Research (COVID-19) and send it to covid-19datasharing@nhsx.nhs.uk. If the request is approved you will then complete the DARS online process in the normal way. Any releases made are subject to increased oversight. Get more information on the GDPPR assessment process agreed upon with the British Medical Association (BMA) and the Royal College of General Practitioners (RCGP), with support from the National Data Guardian (NDG).

Datasets available

 

Adult Psychiatric Morbidity Survey - Provides data on the prevalence of both treated and untreated psychiatric disorder in the English adult population (aged 16 and over).

Cancer Registration Data (details to follow)

Civil Registration – Deaths (details to follow)

Civil Registrations (Deaths) - Secondary Care Cut - Information including the date, place and cause of death from the Office for National Statistics (ONS) 

Community Services Data Set (CSDS)  - A patient-level data set providing information about publicly funded community services for children, young people and adults. These services can include health centres, schools, mental health trusts, and health visiting services. The CSDS superseded the Children’s and Young People Health Services Data Set (CYPHS).

Demographics (details to follow)

Diagnostic Imaging Data Set (DID) - Data on NHS-funded diagnostic imaging tests, such as MRI scans and x-rays, extracted from NHS providers' radiological information systems.

Emergency Care Data Set (ECDS) -The database containing details of all A&E attendances at NHS hospitals in England, including minor injury units and NHS walk-in centres, as well as 24 hour and consultant-led emergency departments. The ECDS will eventually replace the Hospital Episodes Statistics: Accident & Emergency (HES AE) data set.

HES linked to Civil Registrations (Deaths) - Linking HES data to mortality data from the Office for National Statistics permits the analysis of deaths in and outside hospital for all patients with a record in HES. It is also a rich source of data for analysis on a wide range of subjects including outcomes of hospital care, such as postoperative mortality.

HES linked to DID - The linkage of HES to DID enables customers to analyse acute secondary care pathways for patients receiving diagnostic imaging tests in England. This analysis could help to identify trends and variation in patient outcomes and be used to improve services for patients.

HES linked to Mental Health data - The linkage between HES and MHMDS/MHLDDS/MHSDS is provided as a bridging file which enables mental health records to be matched with records in HES through a pseudonym that protects the identity of individual patients. This enables analysis of acute patient pathways for mental health service users in England, which could be used to assess equality of access or identify opportunities for service improvement.

HES linked to PROMS - Linking PROMS to hospital inpatient episodes data from HES gives a much richer data set which provides the ability to analyse the data by patient demographics and by the extensive procedure and diagnosis information which are present in HES.

Hospital Episode Statistics (HES) - Over 1 billion records of patients attending accident and emergency units, admitted for treatment or attending outpatient clinics at NHS hospitals in England.

Improving Access to Psychological Therapies (IAPT) - A patient-level, secondary-uses data set, which provides nationally consistent and comparable person-based information about people referred to IAPT services for depression and anxiety. It contains information extracted or derived from local information systems within NHS-commissioned services across England.

Maternity Services Data Set (MSDS) - A patient-level data set that captures information about activity carried out by Maternity Services, relating to a mother and baby(s). It covers all activities from the point of the first booking appointment until mother and baby(s) are discharged from maternity services.

Mental Health data (MHMDS, MHLDDS, MHSDS) - Includes adults in receipt of NHS funded specialist, secondary mental health or learning disability services.

National Diabetes Audit (NDA) Core - One of the largest annual clinical audits in the world. It measures the effectiveness of diabetes healthcare against NICE Clinical Guidelines and NICE Quality Standards in England and Wales, for both primary and secondary care.

NHS Registration Data from the Personal Demographics Service - The Personal Demographics Service (PDS) is the national electronic database of NHS patient demographic details such as name, address, date of birth, NHS Number and registered GP.

Patient Reported Outcome Measures (PROMs) - Pre and post-operative survey data collected from patients receiving hip replacement, knee replacement, hernia and varicose vein surgery.

Personal Social Services – Adult Social Care Survey (ASCS) – An annual national survey, conducted by Councils with Adult Social Services Responsibilities (CASSRs), gathering information from a sample of services users; aged 18 and over; in receipt of long-term support services funded or managed by social services.

Personal Social Services – Survey of Adult Carers [in England] (SACE) – A biennial survey, conducted by Councils with Adult Social Services Responsibilities (CASSRs), collecting information from and about adult carers, caring for a person aged 18 or over, who have been assessed or reviewed by social services (or where the cared-for person has received respite or another form of carer support).

Secondary Uses Service Payment by Result (SUS PbR) - National secondary care payment information from the Secondary Uses Service.

Summary Hospital-level Mortality Indicators (SHMI)  - The SHMI is the ratio between the number of patients who die following hospitalisation at the trust and the number that would be expected to die on the basis of average England figures, given the characteristics of the patients treated there. It includes deaths which occurred in hospital and deaths which occurred outside of hospital within 30 days of discharge.
