Study name	A pragmatic cluster population‐level randomised controlled trial of a community‐level intervention to increase early uptake of antenatal care (REACH Pregnancy Programme, Work Package 1)
Methods	Matched cluster‐RCT; unit of randomisation: electoral ward n = 10
Participants	Wards: electoral wards, covered by maternity care providers enrolled on the study, where the proportion of women who have their first antenatal appointment by 12 weeks is below the NHS national target of 90% Participants: women in the selected electoral wards who give birth, at a hospital enrolled in the study, over a 12‐month period
Interventions	Using a co‐production process engages with local communities to identifying their perceptions/views on the issues and solutions to increase early booking for antenatal care; tailoring the design of the intervention and form and content of key intervention messages; and facilitating the communication of the intervention messages through community self‐help and local social networks compared with usual practice
Outcomes	Timing: baseline; first follow‐up (2‐7 months) and second follow‐up (8‐12 months): gestation at booking, antenatal admissions, emergency caesarean rates, gestation/weight at delivery, maternal/infant death, APGAR score, smoking, feeding; Other outcomes: feasibility, acceptability, fidelity and economics via interview/observations and reach, exposure, and acceptability via survey.
