The purpose of a descriptive study by Fritschi and colleagues was to document the experience of wearing a continuous glucose-monitoring (CGM) device in women with type 2 diabetes (T2DM). The availability of CGM has provided patients and clinicians with the opportunity to describe the immediate effects of diet, exercise, and medications on blood glucose levels; however, there are few data that have examined patients' experiences and acceptability of using CGM. Thirty-five women with T2DM wore a CGM for three days. Semi structured interviews were conducted to capture the self-described experience of wearing a CGM. Three open-ended questions were used to guide the participants' self-reflection. Interviews were transcribed and analyzed. The women verbalized both positive and negative aspects of needing to check their blood glucose more frequently and wearing the monitor. After viewing the results, most women were surprised by the magnitude and frequency of blood glucose excursions. They immediately examined their behaviors during the time they wore the CGM. Independent problem-solving skills became apparent as they attempted to identify reasons for hyperglycemia by retracing food intake, physical activity, and stress experiences during the period of CGM. Most importantly, the majority of women stated they were interested in changing their diabetes-related self-care behaviors, especially eating and exercise behaviors, after reviewing their CGM results.

WHAT THE STUDY MAY MEAN TO YOU AS A HEALTH CARE PROVIDER: The authors concluded that CGM is generally acceptable to women with T2DM, and offers patients and their health care practitioners a possible alternative to routine glucose monitoring for assessing the effects of real-life events on blood glucose levels.

WHAT THE STUDY MAY MEAN TO YOU AS A PATIENT: If you have type 2 diabetes, continuous glucose monitoring provides you with information as to how your behaviors change your condition. What was impressive in the study was how the women reviewed their immediate past behaviors and altered them when possible. The study proved an interesting contribution to self-management, particularly through the use of self-monitoring.
