Practice Based Research Networks (PBRN)
The current evidence base on how best to organize, finance, and deliver public health services across U.S. communities remains thin, leaving policy-makers and public health officials with limited empirical guidance for improving their programs and policies.
The purpose of this project is to use practice-based research networks (PBRNs) to
(a) expand the volume and quality of research on public health systems and services, and
(b) enhance the ability of state and local public health organizations to translate and apply research findings through evidence-based practice.
Developing a PBRN
This project will test models for developing and operating PBRNs comprised of state and local public health agencies working in collaboration with public health researchers. PBRNs have the potential to stimulate and support research in a number of important areas relevant to public health practice. PBRNs may provide ideal settings in which to test the effectiveness of alternative methods for facilitating the adoption of evidence-based programs and practices, such as those inventoried in the Guide to Community Preventive Services. PBRNS may also provide unique opportunities for studying the effects of administrative and policy changes, such as:
• Comparative case studies designed to identify problems and/or innovations in how public health activities are currently implemented in different practice settings.
• Large-scale observational studies designed to evaluate practice variation across local and/or state public health settings in order to identify opportunities for reducing unnecessary, inefficient, or harmful variation.
• Intervention studies and community trials designed to test the effectiveness and cost-effectiveness of new public health programs. Such studies may also test the effectiveness of quality improvement initiatives directed at existing programs.
• Policy evaluations and natural experiments designed to monitor the effects of key policy and administrative changes made at local and/or state levels, such as new or rescinded public health laws and regulations, shifts in program funding or staffing levels, and organizational restructuring such as service consolidation, regionalization or decentralization.
Major Objectives and Activities
The Public Health PBRN Initiative will accomplish the following objectives and activities over its four-year period of study:
1. Develop a feasible and replicable model for organizing and operating public health PBRNs. This model will assure that PBRNs have the institutional infrastructure necessary to design and mount rigorous studies quickly, efficiently, and accurately in public health settings.
2. Select and fund up to 15 operational public health PBRNs within the U.S. Each network will be comprised of collaborating state and local public health agencies and their community partners, working with a research institution.
3. Operate a national coordinating center that provides technical assistance and support to PBRNs in designing, funding, and conducting public health systems and services research.
4. Facilitate the design, implementation, and translation of new public health research studies through PBRNs. The national program office will assist each PBRN in developing and launching an individual research project conceived by network participants. Additionally, the office will coordinate a larger, “multi-center” research project that is national in scope and involves collaboration across multiple funded networks.
