ADAPTE with modified Delphi supported developing a National Clinical Guideline: stratification of clinical risk in pregnancy.

Objectives: Adaptation has been proposed as an alternative to de novo development to take advantage of existing clinical guidelines (guidelines) and reduce duplication. We describe the process of incorporating a modified Delphi method to reach formal consensus and inform locally relevant clinical recommendations during the development, through the ADAPTE process, of the Irish National Clinical Guideline No. 23 Stratification of Clinical Risk in Pregnancy.
