| Popis: | Objective To evaluate patients’ preferences for various attributes of insulin treatment, including route of insulin delivery. Methods We used a discrete choice experiment (DCE) to quantify patients’ preferences. The attributes (and levels) included in the DCE questionnaire were: glucose control, frequency of hypoglycemic events, weight gain, route of administration for the long-acting and the short-acting insulin, and out-of-pocket cost. Data were analyzed using conditional logit regression and segmented models were also developed to evaluate differences in preferences between subgroups. Results Two hundred and seventy-four questionnaires were completed. The mean age (SD) of participants was 56.7 (12.9) years. Forty-nine percent of participants were insulin users, and 17% had type 1 diabetes. Overall, patients’ ideal insulin treatment would provide better glucose control, result in fewer adverse reactions, have the lowest cost, and be administered orally. Overall, there was a strong positive preference for better glucose control relative to the other attributes. Segmented analyses by insulin use and type of diabetes suggest that there may be an important psychosocial barrier to initiating insulin therapy but that patients tend to adjust to subcutaneous administration once they initiate therapy. Conclusions This study illustrates the importance that patients with diabetes place on glucose control and how preferences for insulin therapy differ between subgroups. Specifically, efforts need to be made to overcome the psychosocial barriers to initiating insulin therapy which may lead to improved control through improved treatment acceptance and ultimately improve patients’ quality of life and reduce the economic burden of the disease. |
