Abstract
OBJECTIVE: Human papillomavirus (HPV) vaccination rates in the United States have been lower than anticipated since the vaccine became widely available globally in 2006. Of particular concern are data that suggest disparities in vaccine receipt among US ethnic minority and health disparity populations such as Hispanics, who are disproportionately affected by cervical cancer. Given these trends, it is important to examine actual vaccination decision-making processes among clinicians, parents, and adolescents to identify strategies to enhance uptake. DESIGN: We conducted a mixed-method study examining HPV vaccine decision-making, utilizing both structured questionnaires of primarily Hispanic mothers and daughters (aged 12-18) and semi-structured interviews with mothers, daughters, and health-care clinicians to more deeply investigate decision-making dynamics. Quantitative analysis was used for descriptive purposes, while qualitative analysis featured an iterative process to examine factors related to decision-making surrounding the HPV vaccine. The study was conducted in two primary care clinics serving predominantly Hispanic patients in an urban New Mexico setting through Research Involving Outpatient Setting Network (RIOS Net), a primary care practice-based research network. RESULTS: We administered 22 questionnaires and conducted 30 interviews. We identified three aspects of vaccine delivery that were similar across clinics: availability/supply of the vaccine, favorable clinician attitudes toward the vaccine, and clinicians' competing demands. We also identified three decision-making stages (pre-encounter, encounter, and post-encounter), though we found distinct differences in decision-making processes at the two sites. We describe the differences between an encounter-based and a process-based model of decision-making, and the ways in which explanatory factors might influence the decision-making process. CONCLUSION: Our findings suggest that factors other than race and ethnicity, such as education, socioeconomic status, and health-care access, play an important role in HPV vaccination decisions. Further research to elucidate the specific informational needs and communication strategies associated with these factors will be needed to enhance vaccine uptake.
