Introduction: The aim of the project was to describe the preferences related to the medication attributes of people with diabetes mellitus (DM) treated in Spain. Methods: The project was carried out in four different phases. In phase A, a Steering Committee defined and selected a total of 18 attributes for treating DM and grouped them into four categories: health outcomes, adverse events, treatment characteristics and cost of treatment. In phase B, a questionnaire according to a discrete choice experiment (DCE) methodology was developed. In phase C, the online DCE survey was sent to members of associations of people with DM from the Spanish Diabetes Federation (FEDE). Finally, in phase D, the results were discussed in a deliberative process. Results: Of the 238 participants who completed the questionnaire (May–September 2020), 231 were included (mean age, 58 years; males, 62%). The DCE results showed that the best-valued category was health outcomes (39.67%), followed by adverse events (26.85%), treatment characteristics (21.70%) and treatment costs (11.77%). Ten of 18 attributes had a significant effect on participants' choice (p < 0.05) and the highest relative importance value: blood pressure reduction (12.82%), hypoglycaemia (12.77%), HbA1c level reduction (8.54%), cost of the medication (8.13%), needle/tablet size (7.20%), weight change (6.72%), risk of genitourinary infections (6.36%), gastrointestinal problems (5.82%), improved kidney function (5.53%) and administration route (5.41%). Conclusions: People with DM prefer a treatment that generates benefits in measurable health effects (reducing blood pressure and HbA1c level, while not risking hypoglycaemia) and a convenient route of administration. Considering the preferences of people with DM could generate better clinical results and therapeutic adherence, reducing morbidity, mortality and disease burden. [ABSTRACT FROM AUTHOR] |
