Patient Preferences for Pharmacological Diabetes Treatment Among People with Diabetes in Spain: A Discrete Choice Experiment

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%), HbA_1c 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 HbA_1c 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.

[Development of the Agreement of the Council of Ministers approving instructions to update the catalogue of medical causes of exclusion in access to public employment.]

The Agreement of the Council of Ministers of November 30, 2018 approving instructions to eliminate certain medical causes of exclusion in access to public employment, such as HIV, diabetes, celiac disease and psoriasis, has meant an important advance in the protection of the labor rights of people in these conditions. Since then, the tables of medical exclusions have been revised and modified for the National Police, National Police, the Civil Guard, the Customs Surveillance Corps, the Corps of Penitentiary Institutions Assistants, the Military Training Centers, the Training Centers, for the incorporation to the Troops and Marines scales and the National School of Police. In addition, the repeal of the Orders of the National Police (Order of January 11, 1988) and the regulatory modification of the Civil Guard (Order PCI/155/2019) guarantee that the diagnosis of HIV, diabetes, celiac disease and psoriasis, will continue without being an impediment for access to the National Police and the Civil Guard in the calls for the next exercises. So, that the mere diagnosis of a disease such as HIV, diabetes, celiac disease and psoriasis will not be a generic cause for exclusion from public employment, but will take into account medical advances and existing scientific evidence, as well as the health situation of each person.
