Studies of inequities in diffusion of medical innovations rarely consider the role of patient-centered care.
We used uptake of the human papillomavirus (HPV) vaccine shortly after its licensing to explore patient-centered care's role.
Using a longitudinal multi-site survey of US parents and adolescents, we assessed whether patient-centered care ratings might shape racial/ethnic and socioeconomic gaps at two decision points in the HPV vaccination process: (1) Whether a medical provider recommends the vaccine and (2) whether a parent decides to vaccinate.
We did not find evidence that patient centeredness's associations with vaccination vary by parent education. In contrast, parent ratings of provider's patient-centeredness were significantly associated with racial/ethnic disparities in parents' reports of receiving a HPV vaccine recommendation from a provider: Among parents who rate patient-centered care as low, white parents' odds of receiving a such a recommendation are 2.6 times higher than black parents' odds, but the racial/ethnic gap nearly disappears when parents report high patient-centeredness. Moderated mediation analyses suggest that patient-centeredness is a major contributor underlying vaccination uptake disparities: Among parents who report low patient-centeredness, white parents' odds of vaccinating their child are 8.1 times higher than black parents' odds, while both groups are equally likely to vaccinate when patient-centeredness is high.
The results indicate that patient-centered care, which has been a relatively understudied factor in medical innovations' unequal diffusion, deserves more attention. Efforts to raise HPV vaccination rates should explore why certain patient groups may be less likely to receive recommendations and should support providers to consistently inform all patient groups about vaccination.
