With regard to our measure of performance (i.e., EPRP data), there is reason to question its accuracy in terms of documentation. Anecdotally, we were told that EPRP data does not necessarily reflect the true state of affairs in reference to guideline adherence. For example, performance may actually occur even though it is not formally documented (e.g., conducting depression screening, though neglecting to record this activity). Conversely, providers admitted to documenting performance that may not have actually occurred (e.g., offering smoking cessation counseling when none was actually given). Because our outcome data may have suffered from documentation errors, the actual effect of knowledge creation on guideline compliance may not have been realized. Also, statistical power was not sufficient to detect potentially meaningful effects. Saal and Knight (1996) recommend a 10:1 case to predictor ratio for estimating statistical power for collection of predictor data. A 31-item instrument would therefore require 310 cases or respondents to yield sufficient power, clearly more than we were able to acquire. Finally, this research must be quantitatively regarded as pilot work toward the development of a survey instrument. Indeed, survey development is an iterative process in which this project was the first iteration.
