Factors associated with physicians' decision to discontinue or down-titrate sulfonylureas for type 2 diabetes patients.

BACKGROUND

Sulfonylureas (SUs) can help manage type 2 diabetes mellitus, but often have side effects. The objective of this study was to identify factors impacting physicians' decisions to discontinue (DC) or down-titrate (DT) SU therapy.

METHODS

1,026 physicians from the All Global panel were asked to rate level of concern regarding potential reasons for DC or DT on a 7-point Likert scale (1 = not concerned, 7 = extremely concerned). Physicians also provided information regarding treatment decisions from one DC patient, one DT patient, and two current SU users.

RESULTS

When asked to report what factors might lead them to DC or DT an SU, physicians reported that hypoglycemic events requiring medical assistance (DC = 6.0, DT = 5.9), hypoglycemic events requiring nonmedical assistance (DC = 5.9, DT = 5.9), other hypoglycemic events not requiring assistance (DT = 5.7), and treatment goals not being met (DC = 5.6) were most concerning. DC and DT patients were more likely to have experienced ≥ 1 hypoglycemic events in the previous year vs. current users (DC = 41.0%, DT = 43.1%, current = 8.8%; p < .05).

CONCLUSIONS

Results highlight the strong influence  of hypoglycemia on physicians' decisions to DC or DT SU therapy.
