Part of National Diabetes inpatient safety audit: Implementation guidance
Data collection
The NDISA audit is a continuous data collection; secondary care services can register at any point during the year and start to submit data. Participating services collect and record data on each qualifying harm. Data is submitted securely online to the NHS England Clinical Audit Platform (CAP). The data is then linked with data items from:
- Core National Diabetes Audit (NDA) primary and specialist adult secondary care collections
- medical data taken from Hospital Episode Statistics (HES) containing details of all admissions, outpatient appointments and A&E attendances at NHS hospitals in England
- mortality data taken from the Office of National Statistics (ONS)
Linkage of the collected data to data from the sources listed above will create the full dataset for analysis and reporting for the NDISA audit.
What data is collected
A list of the items for data collection, including mandatory fields and in-built validations in the clinical audit platform can be found in Table 1.
