Health Professionals' Perceptions of Disparities in Hypertension Control: A Mixed Methods Study

BACKGROUND: Health professionals' commitment is needed to address disparities in hypertension control by ancestry, but their perceptions regarding these disparities are understudied. METHODS: Cross-sectional mixed methods study in a universal healthcare setting in the Netherlands. Snowball sampling was used to include professionals practicing in a large multicity conglomerate including the capital city. Online surveys were collected, and survey participants were randomly selected for in-depth interviews. We used quantitative and qualitative methods to analyze health professionals' awareness, beliefs, and possible interventions regarding these disparities. RESULTS: We analyzed questionnaire data of 77 health professionals (medical doctors n = 70, nurses = 7), whereas 13 were interviewed. Most professionals were women (59%), general practitioners (81%); and White-European (77%), with 79% caring for patients of diverse ancestry. Disparities in hypertension control by ancestry were perceived to exist nationally (83% [95% CI, 75;91]), but less so in health professionals' own clinics (62% [52;73]), or among their own patients (56% [45;67]). Survey respondents emphasized patient rather than provider-level factors as mediators of poor hypertension control by ancestry. The collection of data on patients' ancestry, updating guidelines, and professional training were considered helpful to reduce disparities. Interviewees further emphasized patient-level factors, but also the need to better educate health professionals and increase their awareness. CONCLUSIONS: This explorative study finds that health professionals predominantly attribute disparities in hypertension control to patient-level factors. Awareness of disparities was lower for more proximate healthcare settings. These data emphasize the need to consider health professionals' perceptions when addressing disparities in hypertension control.
