In accordance with Chapter 7 Section 1 of the Patient Data Protection Act (2008:355), a quality register is "an automated and structured collection of personal data that is organised for the purpose of systematic and continuous improvement and strengthening of the quality of healthcare.".
The Government's proposition 2007/08:126, which underlies the Patient Data Protection Act (2008:355), includes the following comment to Chapter 7 Section 1 on page 256.
"The paragraph defines a quality register as an automated and structured collection of personal data organised for the purpose of systematic and continuous improvement and to ensure the quality of healthcare. Characteristic for these registers is that the compiled data can be used to improve the quality of care at differing levels through comparison with various care providers. The special provisions in this Chapter must be applied to all national and regional quality registers."
In contrast to health data registers, there is no constitutionally-regulated obligation for a care provider to participate in a quality register.
The care provider decides whether or not they wish to take part in a quality register.
