The initial list of tasks and health worker types to be considered for the guideline was developed on the basis of input and insights gained from previous technical consultations and regional meetings on safe abortion in Riga, Latvia (May 2012), Addis Ababa, Ethiopia (September 2012), Kathmandu, Nepal (September 2012), and Nairobi, Kenya (November 2012). Additionally, an online questionnaire was sent to a purposively selected group of approximately 90 knowledgeable individuals to help define some of the relevant health worker categories, country-level practices and health worker roles. Responses were received from 35 people many of whom provided further input on national policies relating to health worker roles. The preliminary list was finalized in consultation with the GDG. Formulation of questions Agreed on questions on health worker–task combinations were formulated in PICO (population, intervention, comparator, outcome) format. The prioritized outcomes were as follows: • Benefits and harms: – safety: serious adverse events, complications (specific to the task); – effectiveness (specific to the task); – satisfaction of women receiving care with the overall services/health worker providing the care. • Acceptability: – findings reported in qualitative research regarding the extent to which a task-shifting intervention is considered to be reasonable or adequate among women potentially or actually receiving abortion care, and among health workers potentially or actually delivering this care. • Feasibility: – findings from qualitative studies on factors affecting implementation of task-shifting programmes at scale.
