Experimental studies to improve the reliability and validity of regulatory judgments on health care in the Netherlands: a randomized controlled trial and before and after case study.

Rationale, Aims And Objectives: We examined the effect of two interventions on both the reliability and validity of regulatory judgments: adjusting the regulatory instrument and attending a consensus meeting.

Method: We adjusted the regulatory instrument. With a randomized controlled trial (RCT) we examined the effect of the adjustments we made to the instrument.

Evaluating instruments for regulation of health care in the Netherlands.

Objectives: Reliable and valid judgments are necessary for regulatory authorities to merit confidence from care institutions and society and preserve authority. Moreover, limited reliability and validity of regulatory judgments increase the risk of limited improvement of the quality of health care. The goal of the study is to obtain insight in (dis) advantages of different regulatory instruments for regulation of health care.
