While many quality indicators have

While many quality indicators have been developed to evaluate headache care, evidence regarding their reliability, validity and practicality is lacking. They emphasize processes of care rather than outcomes, and ignore structure. Most cover areas of routine assessment, but do not clearly specify the tool or process to be used in evaluation. Others describe desirable treatment in broad terms, including diagnosis, management or administration of particular tests or drugs. None of the identified measures report inter-rater reliability or other psychometric properties. They are not clearly applicable to different levels and locations of headache care. There is no evidence that any of them have been used for quality improvement, although this is presumably the purpose for which they were developed.
