Sexual and reproductive health service delivery and new models of care, including community pharmacy.

Key projects

Current research is aimed at empowering women in contraceptive choices, improving access to postnatal contraception and developing new contraceptives. We are the UK site for a trial of a new six-monthly contraceptive injection.

 Collaboration with national and international groups aimed at improving access to contraception through community pharmacies (ALLIANCE trial, Australia) and improving abortion care (SACHA study, UK, VEMA study Sweden, How far is too far, Canada). Also nationally with a trial to improve options for controlling troublesome bleeding with contraceptive implant (DEBI trial, Nottingham).
