Impact of an Interprofessional Education Intervention and Collaborative Practice Agreements of Expanded Practice Dental Hygienists in Oregon

Purpose: The state of Oregon developed the expanded practice dental hygienist (EPDH), to address oral health care disparities. The establishment of collaborative practice agreements between dental hygienists (DH) and physician assistants (PA), has created a need for interprofessional education (IPE) for future interprofessional collaboration with EPDHs. The purpose of this study was to assess the impact of an IPE intervention on future interest in collaborative practice agreements. Methods: Current and former DH and PA students from Pacific University Oregon (n=420) were invited to participate in an electronic survey. The 39-item survey included questions related to an annual IPE activity and questions related to collaborative practice agreements between PAs and EPDHs. Descriptive statistics were used to analyze the data. Results: A total of 80 DHs and PAs completed the survey for a response rate of 19%. There were high levels of agreement between DHs and PAs in regards to valuing the expertise of other health care providers, teamworking skills and interprofessional collaboration for a better understanding of a patient's condition. Only 18.9% (n=7) of the DH respondents and 25.6% of the PA respondents (n=11) were aware of the collaborative practice agreements for Oregon EPDHs. Conclusion: Participants from DH and PA disciplines agreed patient care is improved by collaborative practice fostered through interprofessional education activities. Multiple approaches may be needed to increase knowledge on the EPDH collaborative practice agreements with PAs in Oregon.
