Table 2 Criteria used to construct and to evaluate the indicators

1. The indicator measured performance of an intervention or treatment with potential health benefits for the patient

2. The indicator was supported by scientific evidence or professional consensus

3. The indicator was under the control or influence of the care provider or health plan

4. Evidence to evaluate the indicator could be found in the medical record and its absence from the record could be considered a marker for poor quality

Criteria used to evaluate the indicators

Criteria for validity

1. Adequate scientific evidence of professional consensus exists supporting the indicator

2. Identifiable health benefits to patients who receive care specified by the indicator

3. Health professionals with significantly higher rates of adherence to an indicator would be considered higher quality providers

4. Most factors that determine adherence to an indicator are under the control of the health professional (or are subject to influence by the health professional).

Criteria for feasibility

1. The information necessary to determine adherence is likely to be found in a typical medical record

2. Estimates of adherence to the indicator - based on medical record data - are likely to be reliable and unbiased.

3. Failure to document the indicator is itself a marker for poor quality
