Abstract
INTRODUCTION: Preeclampsia with severe hypertension, which occurs in 5% to 8% of pregnancies, is a leading cause of maternal and perinatal morbidity and mortality in the US. Early recognition and treatment of hypertensive crises can significantly reduce poor outcomes. A protocol to ensure prompt treatment with antihypertensive medication (intravenous labetalol) was implemented at our institution. OBJECTIVE: To determine adherence to this protocol on the Labor and Delivery Unit. DESIGN: Retrospective chart review was performed for patients admitted to the Labor and Delivery Unit between April 2015 and June 2015. Charts were reviewed if the patient had a diagnosis of chronic hypertension, gestational hypertension, superimposed preeclampsia, preeclampsia with severe features, eclampsia, or stroke in pregnancy. Only patients with confirmed severe blood pressures, in which the protocol would be initiated, were included in the final analysis. MAIN OUTCOME MEASURE: Overall compliance with the entire protocol. RESULTS: Of 178 cases reviewed, 58 (32.6%) had confirmed severe blood pressures. Most patients (n = 46, 79.3%) received a diagnosis of preeclampsia with severe features, and most delivered via cesarean delivery (n = 38, 65.5%). No cases were compliant with the entire labetalol protocol. Of 58 patients, 2 (3.5) adequately repeated a confirmation blood pressure within 5 minutes, and 34 (58.6%) were adequately treated with intravenous labetalol according to protocol requirements. CONCLUSION: Labetalol treatment was appropriately initiated in many cases; however, protocol adherence could greatly improve. Potential factors affecting protocol compliance include shift changes, communication issues, and conflicting protocols. Institutions should review protocol compliance to improve care.
