Abstract Background Defensive practice occurs when physicians provide services, such as tests, treatments and referrals, mainly to reduce their perceived legal or reputational risks, rather than to advance patient care. This behaviour is counter to physicians’ ethical responsibilities, yet is widely reported in surveys of doctors in various countries. There is a lack of qualitative research on the drivers of defensive practice, which is needed to inform strategies to prevent this ethically problematic behaviour. Methods A qualitative interview study investigated the views and experiences of physicians in Australia on defensive practice and its contribution to low value care. Interviewees were recruited based on interest in medico-legal issues or experience in a health service involved in ‘Choosing Wisely’ initiatives. Semi-structured interviews averaged 60 min in length. Data were coded using the Theoretical Domains Framework, which encapsulates theories of behaviour and behaviour change. Results All participants (n = 17) perceived defensive practice as a problem and a contributor to low value care. Behavioural drivers of defensive practice spanned seven domains in the TDF: knowledge, focused on inadequate knowledge of the law and the risks of low value care; skills, emphasising patient communication and clinical decision-making skills; professional role and identity, particularly clinicians’ perception of patient expectations and concern for their professional reputation; beliefs about consequences, especially perceptions of the beneficial and harmful consequences of defensive practice; environmental context and resources, including processes for handling patient complaints; social influences, focused on group norms that encourage or discourage defensive behaviour; and emotions, especially fear of missing a diagnosis. Overall, defensive practice is motivated by physicians’ desire to avoid criticism or scrutiny from a range of sources, and censure from their professional peers can be a more potent driver than perceived legal consequences. Conclusions The findings call for strengthening knowledge and skills, for example, to improve clinicians’ understanding of the law and their awareness of the risks of low value care and using effective communication strategies with patients. Importantly, supportive cultures of practice and organisational environments are needed to create conditions in which clinicians feel confident in avoiding defensive practice and other forms of low value care.

Abstract Background The patient–clinician interaction is a site at which defensive practice could occur, when clinicians provide tests, procedures and treatments mainly to reduce perceived legal risks, rather than to advance patient care. Defensive practice is a driver of low‐value care and exposes patients to the risks of unnecessary interventions. To date, patient perspectives on defensive practice and its impacts on them are largely missing from the literature. This exploratory study conducted in Australia aimed to examine the views and experiences of healthcare consumer representatives in this under‐examined area. Methods Semi‐structured interviews were conducted with healthcare consumer representatives involved in healthcare consumer advocacy organisations in Australia. Data were transcribed and analysed thematically. Results Nine healthcare consumer representatives participated. Most had over 20 years of involvement and advocacy in healthcare, including personal experiences as a patient or carer and/or formal service roles on committees or complaint bodies for healthcare organisations. Participants uniformly viewed defensive practice as having a negative impact on the clinician–patient relationship. Themes identified the importance of fostering patient–clinician partnership, effective communication and informed decision‐making. The themes support a shift from the concept of defensive practice to preventive practice in partnership, which focuses on the shared interests of patients and clinicians in achieving safe and high‐value care. Conclusion This Australian study offers healthcare consumers' perspectives on the impacts of defensive practice on patients. The findings highlight the features of clinician–patient partnership that will help to improve communication and decision‐making, and prevent the defensive provision of low‐value care. Patient or Public Contribution Healthcare consumer representatives were involved as participants in this study.
