Data in the General Practice Appointments Data (GPAD) collection is known to contain a number of data quality issues. This is due to variation in working methods and recording between different practices. Practices manage their appointment books in the way they best feel allows them to manage the health and care of their patients and not for the purpose of data analysis and there is a widespread variation in approach to appointment management between practices.
A number of other factors must also be taken when interpreting practice level data including:
- The demographics of the patients registered at the practice. For example, practices are likely to have differing age profiles of patients which in turn will impact on the demand and nature of appointments required.
- The level of deprivation in the local area served by the practice and the impact of this on the prevalence of long term illnesses.
- The number of care homes the practice offers services to.
- The use of list and untimed appointments. These appointments are included in the GP system and serve as lists of activities that need to happen at any point in the day and often include telephone triage lists and home visits. These may appear in the appointment book as one appointment whereas other practices may record these as individual appointments throughout the day.
Each of the individual measures (e.g. appointment mode, health care professional type, national category) within the publication have specific data quality considerations.

Practices and PCN's are able to view their own data on the GP Appointments Data Dashboard in order to identify potential data quality issues within the data that NHS Digital holds for their practice/PCN. For more information on the dashboard and how to access it click here.
