To develop the necessary knowledge and evidence base, we require commitment and contributions from the leading proponents and users of the QIC method (for example, HRSA, IHI, and NHS), as well as researchers and research funding agencies worldwide. Several actions are needed. First, organizations with considerable investment in the QIC method should help establish an online information clearinghouse to list and summarize completed, in-progress, and planned evaluations. This listing would facilitate awareness and application of evaluation findings. Clearinghouse contents should include published reports, supplemental details of methods and findings (often excluded from published reports because of space limitations), and evaluation instruments and tools (to facilitate replication and use in subsequent evaluations, thereby increasing comparability of evaluation results and efficiency in use of evaluation resources). Access to “public use” data sets would facilitate additional analyses and insights into the effectiveness of the QIC method. An expanded Web site that offers templates and guidance in conducting appropriate evaluations would further stimulate and support such evaluations. Valuable components of such guidance would include descriptions of quantitative and qualitative data collection and analysis methods (addressing both impact and process evaluations), suggested data sources, a compendium of suitable research designs (documenting their strengths and weaknesses), and sample institutional review board applications.
