Identifying System-Level Strategies to Engage in HPV Prevention Across Oral Health and Primary Care Settings.

Abstract

Introduction: HPV vaccination prevents most HPV-related cancers, yet uptake remains low. HPV is linked to an estimated 70% of oropharyngeal cancers (OPCs) in the US and outnumber cases of HPV-related cervical cancers. Not all OPCs can be detected through routine screening, making HPV vaccination a more effective primary prevention strategy. However, bridging primary and oral healthcare faces challenges due to a lack of referral networks between practices. The purpose of this study is to identify key infrastructure elements and policies, as well as HPV prevention strategies, among an academic practice network of dental clinics and partnering community health clinics in a southeastern state.

Methods: Researchers held interviews with directors and focus groups with staff at six dental clinics and eight associated community clinics in a southeastern state. Interviews and focus groups at dental and community clinics were analyzed by two study team members using thematic analysis with Nvivo software.

Results: A total of 90 participants participated in all focus groups and interviews (N = 14 interviews, 10 focus groups (5-13 participants per focus group). Most participants identified as white (58.9%) and female (70%), with an average age of 38.5 years. Researchers identified nine key study themes: three specific to the dental clinics' HPV conversations with patients, two related to community clinics' vaccine provision, and four involving the relationship between the dental and co-located community clinics. Dental clinic staff do not currently discuss HPV with patients. They are open to discussing HPV with patients but anticipate barriers that require preparation to overcome them. Community clinics have demonstrated previous success with HPV vaccination, but patients over the age of 18 face financial barriers to vaccination. Community clinics and dental clinics report that they do not currently have existing referral networks but are open to a referral system between practices if infrastructure is put into place to support it.

Conclusions: Our findings indicate that there is interest in, and potential for, increased discussion of HPV with dental patients and collaboration between dental and community clinics for HPV vaccination referral. The results of this investigation can be used to develop intervention strategies to increase HPV vaccination through referrals between dental clinics and nearby community clinics. Ultimately, this work can reduce health inequities in HPV-related cancers, serve as a model for US dental practices, and possibly influence public health policy.
