OxTalks is Changing
On 28th November OxTalks will move to the new Halo platform and will become 'Oxford Events' (full details are available on the Staff Gateway).
There will be an OxTalks freeze beginning on Friday 14th November. This means you will need to publish any of your known events to OxTalks by then as there will be no facility to publish or edit events in that fortnight. During the freeze, all events will be migrated to the new Oxford Events site. It will still be possible to view events on OxTalks during this time.
If you have any questions, please contact halo@digital.ox.ac.uk
Using Hospital Episode Statistics (HES) data for research
Status: This talk is in preparation - details may change
Hospital Episode Statistics (HES) data is a comprehensive national dataset collected by NHS Digital, capturing detailed information on all inpatient, outpatient, and A&E activity across hospitals in England. With around 16 million episodes of care recorded each year, HES provides valuable insights into patient demographics, clinical diagnoses, and medical procedures, serving as a crucial resource for health services research and policy planning.
This session will cover:
1. How HES data are collected and the purpose behind this national effort
2. What information is included in HES datasets
3. How researchers can effectively use HES data in their projects
4. The challenges and limitations of working with large-scale administrative data
Intended Audience:
Research staff and DPhil students interested in using healthcare data for research.
Learning Objectives:
1. By the end of the session, participants will:
2. Understand how and why HES data are collected
3. Have a basic understanding of what information is recorded
4. Be able to interpret HES data for their own projects and critically appraise its use in others’ research
5. Recognise the limitations and challenges of using HES data in different research settings
