Participation by patients in their own health care improves quality and safety. Question prompt lists (QPLs) can improve participation, particularly with doctors' endorsement. Few data have explored doctors' attitudes on these tools. We sought the experiences and attitudes of general practitioners and other specialists toward patient question asking and QPLs in their practice. In-depth, semistructured interviews and focus groups with purposively selected Australian doctors were conducted. Interview guides were used to explore doctors' experiences of patient question asking, patients' lists, and a sample QPL created using an Australian government-funded online tool, "Question Builder." Recordings were transcribed verbatim and data analyzed thematically using the method by Braun and Clarke. Focus groups with 3 to 9 participants and a further 17 individual interviews were conducted. There was a total of 40 participants, 23 general practitioners and 17 other specialists (e.g., physicians, surgeons, pediatricians). Our analysis was summarized into several themes. 1) The doctors expected, encouraged, and had significant experience of patient question asking and patients' lists. They described many barriers for patients and their efforts to ensure patients had the information they needed. 2) The doctors felt responsible for creating an environment conducive to patient question asking, the delivery of answers, having strategies for unanswered questions, and balancing the agendas of both parties in the consultation. 3) Structured QPLs that prepared patients and facilitated the consultation agenda were viewed positively. The degree of time pressures participating doctors experienced in their context had a strong influence on how they responded to the sample QPL. Doctors in this study expected patients to ask questions and endorsed the benefits of QPLs. However, there were more diverse views about the feasibility of implementing them in practice. Designing QPLs to fit within current workflows, via more succinct and tailored designs, may result in wider doctor acceptance and endorsement, hence maximizing the benefits of QPLs with improved patient participation and patient safety.
