The use of complementary and alternative medicine (CAM) is increasing. Access to CAM through primary care referral is common with some of these referrals occurring through existing NHS contracts. Yet currently little is understood about General Practitioners (GPs) referrals to CAM via an NHS contract.This exploratory qualitative study was designed to explore UK GPs experiences of referring patients to CAM under an NHS contract.Semi-structured interviews were conducted with ten GPs in the UK, purposively sampled, who refer patients under an NHS contract to a private CAM clinic, staffed by medically qualified CAM practitioners. The interviews and analysis were conducted using qualitative methodology Framework Approach.The GPs decision to refer a patient to CAM through an NHS contract is complex and based on negotiation between patient and GP but is ultimately determined by the patients’ openness and motivation towards CAM. Most GPs would consider referral when there are no other therapeutic options for their patients. Various factors, including clinical evidence, increase the likelihood of referral but two overarching influences are crucial; (a) the individual GPs positive attitude to, and experience of CAM, including a trusting relationship with the CAM practitioner; and (b) the patient's attitude towards CAM. In-depth knowledge of CAM was not a vital factor for most GPs in the decision to refer.A CAM referral only took place if the patient readily agreed with this therapeutic approach, and in this respect it may differ from referrals by GPs to conventional medicinal practitioners. Such an approach, then, relies on patients having a positive view of CAM and as such could result in non-equality of treatment access. Increasing knowledge about and evidence for CAM will assist GPs in making appropriate referrals in a timely manner. This study is an initial exploration of this field, and as data saturation may not have been achieved further investigation is warranted to confirm or refute these findings.
