Study Details

Study Description

Brief Summary

The purpose of this study is observe outcomes before and after a change in clinical practice in the threshold for management of severe hypertension in pregnancy and the post-partum period. Outcomes will be observed for 10 months under the current (traditional) clinical blood pressure threshold for acute treatment of hypertension, which is >= 160 millimeters of mercury (mmHg) systolic blood pressure (SBP). This will be followed by one month of education about rationale for the new SBP threshold of >= 180 mmHg and change of clinical guidelines. Then, there will be 10 months of observation after adopting the updated clinical threshold for acute antihypertensive treatment (>= 180 SBP).

Condition or Disease Intervention/Treatment Phase
  • Procedure: Clinical blood pressure threshold of SBP >= 160 mmHg for acute treatment of hypertension
  • Procedure: Clinical blood pressure threshold of SBP >= 180 mmHg for acute treatment of hypertension

Arms and Interventions

Arm Intervention/Treatment
Traditional clinical blood pressure threshold of SBP >= 160 mmHg for acute treatment of hypertension

Procedure: Clinical blood pressure threshold of SBP >= 160 mmHg for acute treatment of hypertension
Patients are treated for hypertension if SBP >= 160 mmHg.

Updated clinical blood pressure threshold of SBP >= 180 mmHg for acute treatment of hypertension

Procedure: Clinical blood pressure threshold of SBP >= 180 mmHg for acute treatment of hypertension
Patients are treated for hypertension if SBP >= 180 mmHg.

Outcome Measures

Primary Outcome Measures

  1. Number of patients with Congestive Heart Failure/Pulmonary Edema, hemorrhagic or ischemic Stroke, Acute Kidney Injury (creatinine > 1.5mg/dL), and/or or Myocardial Ischemia. [during the time of delivery hospitalization (about 2 days to 3 months)]

    The primary outcome is a composite outcome, and will be reported as number of patients who have Congestive Heart Failure/Pulmonary Edema, hemorrhagic or ischemic Stroke, Acute Kidney Injury (creatinine > 1.5mg/dL), and/or Myocardial Ischemia.

Secondary Outcome Measures

  1. Number of patients with non-reassuring fetal heart rate tracing (NR-FHRT) requiring caesarean delivery [at the time of delivery]

  2. Number of patients with Apgar score < 7 at 5 min [5 minutes after birth]

    The Apgar score indicates the status of the newborn infant immediately after birth. Apgar score ranges from 0-10, with a higher score indicating a better outcome.

  3. Number of patients with eclampsia [during the time of delivery hospitalization (about 2 days to 3 months)]

  4. Number of patients with placental abruption [during the time of delivery hospitalization (about 2 days to 3 months)]

  5. Number of patients with posterior reversible encephalopathy syndrome (PRES) [during the time of delivery hospitalization (about 2 days to 3 months)]

  6. Number of patients with hemolysis, elevated liver enzymes, low platelets (HELLP) syndrome [during the time of delivery hospitalization (about 2 days to 3 months)]
