Download to read offline

Pre-eclampsia causes significant death and disability for pregnant women with potential complications for newborns. Beth Payne from the University of British Columbia describes a new application of pulse oximetry to identify the pregnant women most at risk of preeclampsia to prevent adverse outcomes.

  1. 1. PRE-ECLAMPSIA RISK ASSESSMENT IMPROVES WITH PULSE OXIMETRY Beth Payne, PhD Postdoctoral Fellow, UBC
  2. 2. PRE-ECLAMPSIA • Pre-eclampsia – defined by high blood pressure and protein in the urine during pregnancy • Second leading cause of maternal death – 30,000-50,000 maternal deaths annually • Perinatal deaths largely due to increased incidence of preterm birth associated with disease • Deaths could be prevented with access to effective antenatal care and timely intervention Why does it matter?
  3. 3. • Mobile phone based decision aid for community health workers combining: – Validated risk assessment model – Mobile pulse oximetry • Supports task-shifting of evidenced-based antenatal care to existing community health workers, improving access to effective ANC OUR PROPOSED SOLUTION PIERS on the Move
  4. 4. • Guides community health worker through antenatal assessment and provides recommendations for follow-up care based on risk model PIERS ON THE MOVE Supporting healthcare decision making in the community
  5. 5. • How important is pulse oximetry for risk assessment? • Low SpO2 increases risk of complications 30-fold – additional 18.5% of women with complications being correctly identified as high-risk • Correctly identifying risk prior to complications will save lives! (Payne et al. JOGC 2015) PULSE OXIMETRY FOR PRE-ECLAMPSIA
  6. 6. • How important is pulse oximetry for risk assessment? – Low SpO2 increases risk of complications 30-fold – Correctly identify additional 18.5% of women as high-risk • Correctly identifying risk prior to complications ensures timely access to care and saves lives! (Payne et al. JOGC 2015) PULSE OXIMETRY FOR PRE-ECLAMPSIA
  7. 7. IMPLEMENTATION AT SCALE Community Level Interventions for Pre-eclampsia (CLIP) • Cluster randomized controlled trial in Mozambique, Pakistan and India • Assessing impact of PIERS on the Move tool on maternal and perinatal outcomes • https://pre-empt.cfri.ca/
