• Abstract only Background: Severe hypertension is an obstetric emergency. Timely identification and management can reduce risk of serious events. Aims of our study were to 1)assess whether severe hypertension is being recognized and managed within the recommended time frame and 2)evaluate the factors that are associated with timely identification and treatment of severe maternal hypertension. Methods: A retrospective study of pregnant and postpartum women presenting with severe hypertension to tertiary care hospital between 1/1/19 to 12/1/19. Main outcome measures were ‘time to repeat blood pressure check(TTC)’ and ‘time interval between confirmation of severe hypertension and initiation of pharmacotherapy(TTT)’. We examined the association of the type of hospital unit, time of day of presentation and race/ethnicity with the outcome measures. Results: A total of 656 women were included in the study. Median time for repeat blood pressure check was 16 minutes. Only 46.2% of women had a repeat blood pressure check within 15 minutes. Median interval between confirmation of severe hypertension and initiation of therapy was 38.5 minutes. 63.3% of women were treated within the recommended time frame of 60 minutes. Both timely blood pressure re-check(15.6% vs 51.4%, p < 0.001) and initiation of treatment(38.5% vs 70.8%, p < 0.001) were significantly lower in the emergency department (ED). TTC(57.9% vs 31.4%, p < 0.001) and TTT(86.4% vs 42%, p < 0.001) were significantly better in the labor and delivery unit. Time of day(day 51.6% vs night 57.3%, p = 0.15) and race/ethnicity(black 57.1% vs non-black 51.6%, p = 0.16) were not associated with delay in repeat blood pressure check. However, black race(46.2% vs 28.6%, p = 0.018) was associated with delayed initiation of therapy compared to non-black patients. Conclusions: We found both the rates of timely identification and treatment of severe maternal hypertension in the ED were lower compared to other units. This points to need for continuous education of ED healthcare providers about timely recognition and management of severe maternal hypertension. We also found racial disparities in timely initiation of therapy, thus demonstrating the need for standardization of protocols.
