Research
|
Low level of evidence. For example, results of individual case studies
|
High level of evidence. For example systematic reviews, or adoption by regional or national health bodies
|
Accuracy
|
The indicator only measures a small part of the standards, or is not sufficiently or independently verified
|
The indicator measures whether the accreditation intervention has been implemented or the service provided in accordance with the standard
|
Proximity
|
Multiple steps or processes between the indicator measurement and accreditation standard make it difficult to link the indicator with the effects of accreditation
|
Close temporal or process links exist between accreditation surveys and the indicator measurement
|
No adverse effects
|
Measurement or publication of results gives incentives for gaming or misallocation of resources
|
Indicator measurement or publication does not give rise to unintended adverse effects or consequences
|
Specificity
|
Multiple and recent policy initiatives covering the same topic as the accreditation standard under discussion
|
Accreditation is the main policy implementation tool
