Data receipt	Data quantity	Data accuracy and completeness
1. All participating organisations have provided data for each of their service areas*	2. Data received is stable over time (i.e. within expected stochastic tolerances for month-to-month changes)	4. All data items include key variables (such as those listed in the ‘data contents’ section)
	3. Data volumes are comparable with external reference data, such as published numbers of hospital admissions, accident & emergency attendances and GP consultations.	5. Coding of events (such as Read Codes) appears consistent across data providers
