Assessment of the complexity of drug therapy and psychosocial and behavioral aspects in people living with type 2 diabetes mellitus.

Background Type 2 diabetes mellitus is a public health problem worldwide. The complexity of drug therapy and behavioral aspects are important factors in its management. Objective To characterize the complexity of drug therapy, attitudes, empowerment and self-care in people with type 2 diabetes mellitus. Methods Observational descriptive study involving people with type 2 diabetes mellitus recruited in eight public primary care settings in Brazil, 2018. We used validated instruments to determine the complexity of drug therapy employing the Medication Regimen Complexity Index, and to describe the behavioral aspects, encompassing Diabetes Attitudes Questionnaires, Diabetes Empowerment Scale-Short Form and Diabetes Mellitus Care Self-Management. Results The 119 participants showed median age of 64 years (Quartile 1 57.0; Quartile 3 71.0) with predominance of women (68.1%). We found high percentages of participants with low scores on attitudes (87.9%) and self-care (84.8%) questionnaires, but with high scores on empowerment questionnaire (81.8%) in groups with high complexity of drug therapy. Conclusion High complexity of drug therapy concentrated low scores for attitudes and self-care, even though presenting elevated empowerment scores. Further studies are needed to investigate the effect of these aspects on the behavior of people with type 2 diabetes mellitus on drug therapies of high complexity.
