Key result
Among surveyed Canadian specialists, 63.6% preferred office blood pressure measurement for diagnosing hypertension in pregnancy, while 59.4% relied on home monitoring for ongoing management.
Why the study?
Hypertension guidelines recommend out-of-office measurements in non-pregnant adults whereas pregnancy guidelines recommend in-office measurements, leaving practice patterns among Canadian specialists uncertain.
Cross-Sectional (n=33)
Yes
There is wide practice variation among Canadian specialists in methods of measuring blood pressure for managing hypertension in pregnancy, with a preference for office measurement for diagnosis but home monitoring for ongoing management.
Survey data reveal practice variation in pregnancy hypertension monitoring; leaves open need for standardized guidelines and prospective trials.
BACKGROUND: Multiple hypertension guidelines recommend out-of-office measurements for the diagnosis of hypertension in non-pregnant adults, whereas pregnancy guidelines recommend in-office blood pressure measurements. The objective of our study was to determine how Canadian Obstetric Medicine and Maternal Fetal Medicine specialists measure blood pressure in pregnancy. METHODS: An email survey was sent to 69 Canadian Obstetric Medicine and Maternal Fetal Medicine specialists in academic centers across Canada to explore the practice patterns of blood pressure measurement in pregnant women. RESULTS: The response rate was 48%. The majority of respondents (63.6%) preferred office blood pressure measurement for diagnosing hypertension, but relied on home blood pressure readings for ongoing monitoring and management of hypertension during pregnancy (59.4%). The preferred method of out-of-office blood pressure measurement was home monitoring; 24-hour ambulatory blood pressure monitoring was not used due to limited availability and cost. CONCLUSIONS: There is wide practice variation in methods of measuring blood pressure among Canadian specialists managing hypertension in pregnancy.
