We set out to measure the standards of care in a regional cohort of women with severe hypertensive illness of pregnancy and to subsequently improve the quality of care using a series of interventions. This was a multi centre cyclical criterion audit involving 21 maternity units in the West Midlands Region. Prospective data collection involved named co-ordinators in each unit using customised proformas. Intervention comprised feedback of baseline results to each hospital, a monitoring chart and eclampsia treatment pack. The first audit period (n = 183) was for a 4-month period between 1/9/96 and 31/12/96 and the second audit period (n = 111) was during the same 4-month period 1 year later. Although compliance with the audit standards set increased in all but one standard, there is clearly a need to make further improvements in the quality of care administered.

Objective: To study the management of a series of women presenting with acute-onset hypertension in the 21 maternity units in the West Midlands region, in order to measure the standard of care and the outcomes of these patients and their babies., Design: Multicenter audit., Setting: Twenty-one Maternity Units in the West Midlands region with 85,658 births during the audit period., Methods: Prospective data collection by named coordinators (multidisciplinary) in each unit using customized proformas. The proformas were then forwarded to the Research Coordinator for input onto a database and observational analyses., Results: The total number of cases was 516. Eighty-one percent were diagnosed as having severe preeclampsia, 14% HELLP syndrome, and 5% eclampsia. Seven percent were admitted to the intensive therapy unit. Seventy percent of births were preterm, 62% of babies were low birth weight (< 2.5 kg), 57% of babies were admitted to the neonatal unit, and the perinatal mortality rate was 5%. The commonest antihypertensive agents were hydralazine and nifedipine. In terms of compliance with audit standards, 61% had both oxygen saturation and noninvasive blood pressure monitoring, 47% had good fluid balance documentation, and 79% had no fluid mismanagement. Seventy-four percent were seen by a consultant obstetrician, 62% were seen by a member of an "expert team," 83% adhered to local guidelines, and 71% of eclamptics received magnesium sulfate (MgSO4)., Conclusion: Our study shows that severe hypertensive illness of pregnancy remains an important cause of maternal mortality and perinatal mortality. This audit highlights areas in which standards of care can be improved.
