Elimination of racial disparities in postpartum hypertension follow-up after incorporation of telehealth into a quality bundle.

ABSTRACT

BACKGROUND: Black people have a disproportionately higher risk of hypertensive disorders of pregnancy and postpartum complications than White people but historically lower rates of postpartum follow-up. Few studies have investigated telehealth in the postpartum population. OBJECTIVE: This study aimed to investigate whether rapid switch to telehealth with audio-based visits during the COVID-19 pandemic decreased racial disparities in postpartum hypertension follow-up adherence. STUDY DESIGN: This retrospective cohort study included all the patients with hypertensive disorders of pregnancy who delivered between December 2019 and June 2020 at an urban tertiary care center. A preexisting postpartum hypertension quality improvement initiative was in place at this institution. Follow-up adherence within 6 weeks postpartum and at the 6-week visit were compared before February 15, 2020 (pretelehealth period) and following March 14, 2020 (post-telehealth period), with a 1-month implementation or washout period. The blood pressures at these visits were compared between time periods as a secondary outcome. RESULTS: A total of 473 patients were included in this analysis, of whom 76.3% were non-Hispanic Black. There were 215 and 258 patients in the pre- and post-telehealth cohorts, respectively. Among those who attended follow-up, the proportion of visits done over telehealth went from 0% pretelehealth to 98.0% post-telehealth. The proportion of postpartum hypertension follow-up attendance changed from 48.5% to 76.3% among non-Hispanic Black people (P<.0001) and from 73.1% to 76.7% among non-Hispanic White people (P=.76), leaving only a 0.4% racial gap (P=.97). This resulted in an elimination of the racial disparities in the post-telehealth period. CONCLUSION: Transition to telehealth with audio-based visits at the onset of the COVID-19 pandemic improved attendance at postpartum hypertension visits among non-Hispanic Black people. This, therefore, led to significant decreases in the racial disparities in follow-up rates at our institution in the setting of an existing quality improvement initiative. Further research should focus on the intentional use of telehealth in improving maternal outcomes, especially among the non-Hispanic Black people.
