Core Outcome Measures in Effectiveness Trials

Core Outcome Set for Sickle Cell Disease in Pregnancy

General Information

Summary:
Sickle cell disease (SCD) is one of the most common hereditary hemoglobinopathies, accounting for approximately 28,600 deaths in 2010. Pregnancy in women with SCD is currently viewed more favorably; however, adverse pregnancy outcomes still occur, resulting in maternal or fetal morbidity and even mortality. Studies to date differ with respect to the outcomes they report, as do the definitions of these outcomes. This hampers the ability to compare, contrast, and combine these study results; a process particularly crucial in study areas, which focus on small populations, where the feasibility of accruing sample sizes necessary to properly power individual studies is sometimes an insurmountable challenge.

The objective of this project is to create a core outcome set for studies focusing on the course and management of SCD in pregnancy.

Method(s)

Consensus meeting
Delphi process
Literature review
Systematic review

A systematic review of RCTs and cohort studies will be undertaken to index all reported outcomes and their definitions. Health service user input will be sought to further complement the outcomes compiled through the systematic review. The Delphi methodology will then be utilized to reach consensus among stakeholders with regards to a core outcome set. The outcome set identified through the Delphi method will then be refined via a consensus meeting.
