Description of intervention(s) / exposure
Eligible participants (i.e. using an insulin pump with diabetes and aged 65+ years) will be asked to complete a 10-statement survey using the 1000minds decision-making and adaptive conjoint analysis software tool (see https://www.1000minds.com/). Participants will be asked to prioritize the 10 statements, in terms of what they would like to discuss at a routine diabetes clinic visit. Participants will access the survey via a desktop or laptop computer that will be set up with the 1000minds survey ready to go. They will be offered support to complete the online survey, with help from a member of the research team. The survey should typically take 15 minutes or less to complete.
Additionally, participants will be interviewed by a research team member and asked semi-structured questions. These questions will explore their personal views and experiences of using an insulin pump. Baseline demographics and clinical information will also be collected. This questionnaire should also typically take 15 minutes or less to complete and so the total time for the interview (questionnaire and online survey) will be 30 minutes.
Intervention code [1] 327588 0
Not applicable
Comparator / control treatment
Staff with clinical expertise in the care of patients on insulin pumps will be the comparator group. These staff participants will complete a near-identical 1000minds online survey on what is important for them to prioritize with their patients during a diabetes clinic visit. The 1000minds survey will be sent to the staff members via an email link and can be completed in their own time. These staff participants are not interviewed by a research team member unlike the patient participants. They only complete the anonymized online survey.

Statistical methods / analysis
The statements presented to participants for prioritizing will be paired using the 1000minds multi-criteria decision, adaptive conjoint analysis technique. Anonymized individual participant results from patients and staff will be grouped for cluster analysis.
This study is exploratory. It is anticipated that 24 participants will be recruited for each group. No prior information is available that might help with the determination of sample size. For example, 1000minds can detect ‘noise’ (inconsistency) in individual answers and it is unknown how much ‘noise’ that pairwise statements may generate. This information will help inform study design for any future, larger study.
An important aspect of this research is the study co-design process undertaken with relevant clinical stakeholders, including patients. A narrative approach to emerging findings from this co-design process will be therefore another important study outcome.

Data sharing statement
Will individual participant data (IPD) for this trial be available (including data dictionaries)?
No
No/undecided IPD sharing reason/comment
This is a small exploratory study and the quality of the data that might be generated from the study is therefore uncertain. Also, it is unclear in advance if data is truly anonymous or merely de-identifiable. In addition, the semi-qualitative patient questionnaire may include potentially identifiable data.
