Aim: To explore, in general practice settings the concerns, beliefs and attitudes about intrauterine contraception reported by women, who had never used the methods.Method: We used a sequential mixed-method (QUAL/quant) approach. A pragmatic, self-selecting sample of thirty women, aged 18-46 years, who had never used intrauterine contraception (IUC), was recruited through seven general practices in South East England. Themes arising from qualitative interviews were used to construct a quantitative survey, completed by a pragmatic sample of 1195 women, aged between 18-49 years, attending thirty-two general practices in the same region, between February and August 2015.Findings: Qualitative themes were concerns about the long acting nature of IUC, concerns about bodily boundaries, and informal knowledge of IUC, especially "friend of a friend" stories. Women were not sure if the devices could be removed before their full 5 or 10 year duration, and felt that these timeframes did not fit with their reproductive intentions. Quantitative survey data showed that the most commonly endorsed concerns among never-users were painful fitting (55.8%), unpleasant removal of the device (60.1%), and concern about having a device 'inside me' (60.2%).Conclusions: To facilitate fully informed contraceptive choice, information provided to women considering IUC should be tailored to address the concerns expressed by never-users, particularly around the details of insertion and removal, and concerns about adverse long-term effects of the device.Women need to be reassured that IUC can be removed and fertility restored at any time following insertion.
