The START clinic feasibility study: exploring the feasibility of prospective obstetric research with retrospective Artificial Reproductive Technologies (ART) data linkage

The START clinic study recruited 120 participants conceiving by assisted reproductive technologies or spontaneous conception (fresh embryo transfer in-vitro fertilisation (IVF) N=36, frozen embryo transfer N=62, spontaneous conception N=14, ovulation induction N=7). These participants were prospectively observed 4-6 weekly throughout pregnancy, with retrospective linkage to fertility treatment data where possible. The feasibility assessment explored acceptability, possibility and extent of retrospective data access as well as recruitment, retention and acceptability of research measures and observation. This data dictionary outlines routinely collected data taken during the START clinic study, including baseline data questions, consent, visit records, end of pregnancy data, fertility treatment data and questionnaires.
