Why is data quality important to the NHS?
High quality data is important to the NHS as it can lead to improvements in patient care and patient safety. Quality data plays a role in improving services and decision making, as well as being able to identify trends and patterns, draw comparisons, predict future events and outcomes, and evaluate services.
To monitor the quality of data, we ask ourselves the following questions:
- Consistency: How does our current data look compared to the historic picture? Are there unexplained peaks or troughs that need to be investigated?
- Accuracy: Does the data in our system fit what we expect to see? Do data items match with historic submissions?
- Timeliness: Was data submitted in line with deadlines? Are any data providers persistently late in their submissions?
- Efficiency: Is data processed and made available in a timely fashion? Are DQ checks performed as smoothly and efficiently as possible while still maintaining high standards?
- Validity: Are submitted data items valid according to national definitions? Is field population of mandatory data items at expected levels?
- Completeness: Do we have significant gaps in our data? Has a provider missed a submission? Has a provider removed a portion of its historic data?
