Exploring Efficacy, Cost Effectiveness and Experiences Related to Adherence of Different Bisphosphonate Regimens for the Prevention of Osteoporotic Fragility Fractures.

This information provided relates to Stage 1B. Stage 1A does not involve participants. Stage 2 will be conducted by the Royal Osteoporosis Society. Participants will not be invited via NHS (National Health Service) organisations and no identifiable information will be collected.

Participants are only involved in Stage 1B of the study, which consists of qualitative interviews only. Participants will be drawn from several different areas of healthcare, in order to ensure a best range of relevant patients', clinicians', commissioners', service managers' and researchers' experiences. Patient participants will be identified as potentially eligible by their healthcare providers, either via their GP (General Practitioner) surgery or secondary care clinician.

Patients will receive a Study Information Pack via the post, containing an Invitation (Patient) Letter from their GP or responsible secondary care doctor, a Participant (Patient) Information Sheet, a reply slip and a freepost envelope with the Research Team's return address. This information pack will also include the Research Team's contact details in order that potential participants have an opportunity to ask questions before indicating an interest in taking part in the study. Patients may also contact the Research Team to express interest by response to a Patient Information Poster in certain service areas, and they will be supplied with the same Study Information Pack. Patients who return a reply slip will be contacted by a member of the Research Team to arrange a convenient time and location in which to obtain written informed consent and undertake the semi-structured interview, which is likely to be immediately after written consent is obtained.

Non-patient participants will be identified as potentially eligible via their General Practice Managers or via snowball sampling from their Service Lead in secondary care services. They will be provided with an Invitation (Clinician) Letter/Email and Participant (Clinician) Information Sheet. The information pack will also include the Research Team's contact details in order that potential participants have an opportunity to ask questions before indicating an interest in taking part in the study. If they indicate to the Research Team they would like to participate in the study, a member of the Research Team will contact the participant to obtain written informed consent, before arranging a convenient time and location to undertake the semi-structured interview, which may be immediately after written consent is obtained.

The semi-structured interviews will be conducted face-to-face or by telephone and are expected to take 40-50 minutes to complete. Face-to-face interviews will be conducted in a private setting either within the site of treatment or at their home in the case of a patient participant, or within the place of work for non-patient participants.

The interview guide will be developed iteratively throughout the study to cover issues as identified from the scoping review of published studies assessing experiences of bisphosphonate regimens, as well as wider experiences of service quality and delivery. This will include questions around patient factors (such as values and health beliefs), service factors (location, accessibility, assurance, and empathy), relational factors (provider patient relations) and medication factors (dosing complexity, frequency, side effects). Clinician interviews will also include barriers to maintain a service around alternative bisphosphonates regimens, as well as changes in service over time.

Interviews will be undertaken by qualitative researchers (employed by University of Nottingham). Interviews will be audio-recorded and then transcribed by Clayton Research Support, a Nottingham University Hospitals and University of Nottingham approved transcription service.

There is no intervention involved in this study. Once the interview is completed, a participant's involvement in the study is ended. There is no further follow-up.

Thematic analysis of interview data will be conducted. This will involve familiarisation, identification of a framework, and interpretation, paying particular attention to themes clustered around service variables. The analysis will involve a preliminary phase of more general qualitative data analysis (close reading of transcripts, open coding, identification of themes). Analysis will be undertaken in the first instance by the Research Fellow alongside and overseen by the Stage 1B Lead. Emerging themes (with all identifying information removed) will be discussed at appropriate intervals with the wider study management group. The approach will allow for both a-priori and emergent codes to be identified. NVivo software will be used to develop an appropriate coding strategy and framework.

Due to the Covid-19 pandemic and the need for a contingency recruitment plan, Non-substantial Amendment 02 was submitted and approved on 15th May 2020 to facilitate patient recruitment from the Royal Osteoporosis Society members via newsletter article, allowing interviews to be conducted by telephone rather than face-to-face at a specific location.
