Abstract

BACKGROUND: The purpose of this study was to evaluate the impact of symptomatic hypoglycemia on medication adherence, satisfaction with treatment, and glycemic control in patients with type 2 diabetes based on the treatment goals stated in the Swedish national guidelines. METHODS: This cross-sectional, multicenter study was carried out between January and August 2009 in 430 consecutive primary health care patients on stable doses of metformin and sulfonylureas for at least 6 months. The patients completed questionnaires covering their experiences of low blood glucose and adherence, as well as barriers to and satisfaction with drug treatment (using the Treatment Satisfaction Questionnaire for Medication). Physicians collected the data from medical records. RESULTS: Patients who experienced moderate or worse symptoms of hypoglycemia reported poorer adherence to medication (46% versus 67%; P<0.01) and were more likely to perceive barriers such as "bothered by medication side effects" (36% versus 14%; P<0.001) compared with patients with no or mild symptoms. Patients with moderate or worse symptoms of hypoglycemia were less satisfied with their treatment than those with no or mild symptoms as determined by the Treatment Satisfaction Questionnaire for Medication-Global satisfaction (67.0 versus 71.2; P<0.05). Overall, achievement of target glycated hemoglobin (HbA1c) based on the treatment goals stated in the Swedish national guidelines was 40%. Despite poorer adherence, patients who experienced moderate or worse symptoms of hypoglycemia had lower mean HbA1c values than patients with no or mild symptoms (7.0% versus 7.3% [Diabetes Control and Complications Trial standard]; P<0.05). CONCLUSION: Symptomatic hypoglycemia in patients with type 2 diabetes on metformin and sulfonylureas was associated with nonadherence and decreased treatment satisfaction despite lower mean HbA1c values. A broader understanding of patient preferences and self-reported outcomes could improve the management of patients with type 2 diabetes.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
