A list of these persons is at http://www.nationaldentalpbrn.org/collaborative-group.php. mungia@uthscsa.edu.
Purpose:
This study examines practitioner participation over 12 years in the National Dental Practice-Based Research Network (PBRN) studies and practitioner meetings, average length of participation, and association of practitioner- and practice-level characteristics with participation. Little information exists about practitioners' long-term participation in PBRNs.
Methods:
The network conducted a retrospective analysis of practitioner participation in 3 main network activities during 2005 to 2017. Practitioners who completed an enrollment questionnaire, practiced in the United States, and either attended a network meeting or received an invitation to complete a questionnaire or clinical study were included in the analysis. Practitioners (n = 3669) met inclusion criteria. The network implemented 38 studies (28 clinical and 10 questionnaire), 23 of which (15 clinical and 8 questionnaire) met the criteria for the current analysis.
Results:
Overall, 86% (N = 3148) participated in at least 1 network activity during 2005 to 2017. Questionnaire studies had the highest rate with 81% (N = 2963) completing at least 1, 21% (N = 762) completed at least 1 clinical study and 19% (N = 700) attended at least 1 network meeting. Among 1578 practitioners enrolled in the first 5 years of the Network launch, 20% (N = 320) participated in multiple network activities over 5 to 9 years, and 14% (N = 238) for 10 to 12 years. Practitioner characteristics associated with participation varied depending on the activity assessed.
Conclusion:
The network engaged practitioners in its research activities with relatively high participation rates over a 12-year period. Strategies employed by the network to engage practitioners may serve as a model for PBRN networks for other allied health professions.
