Objectives: The National Dental Practice-Based Research Network (National Dental PBRN) has developed a unique infrastructure with six administrative sites that help dental practitioners conduct research with their patients. This infrastructure allows the network to conduct research studies with the capability of enrolling large, diverse numbers of patients in a short time period. Practice-based research models have the potential to increase the ethnic and geographic diversity of patients enrolled, a challenge often faced in academic research.
Methods: Descriptive statistics from five clinical studies enrolling patients from 2014-2017 were analyzed to assess the demographic distribution. Maps that show geographic diversity of patients were developed using ArcGIS.
Results: 12,213 patients enrolled in five National Dental PBRN clinical studies from 2014-2017. Patient enrollment occurred in the majority of states and Puerto Rico. Patients enrolled in these studies were 62% female and 39% male. 82% of patients were Caucasian, 9% African American, 4% Asian, 2% American Indian/Alaskan Native and 0.4% Hawaiian/Pacific Islander. A majority of patients had private dental insurance (68%), while 19% reported not having dental insurance, and 10% had public or governmental dental insurance. Patients’ highest level of education varied with 7% of patients having less than a high school diploma, 14% having a high school diploma, 31% having completed some college, and 46% having received a bachelor’s degree or higher.
Conclusions: The National Dental PBRN successfully enrolled over 12,000 patients from five clinical studies in three years. The network’s structure allows for; 1) increased diversity of patients by reaching segments of the population that cannot access academic research centers and, 2) a model for other research networks looking to increase the volume and diversity of their patient enrollment. This model also makes research participation more accessible for patients by bringing the research to dental offices in their community. Support: U19-DE-22516
