Insulin improves well-being for selected elderly type 2 diabetic subjects

The effects of insulin therapy on patient well-being, treatment satisfaction and mood, and on carer strain were studied in 30 elderly Type 2 diabetic patients (age 73 +/- 7 (SD) yr) in poor glycaemic control on tablet therapy. A comparison group of ten poorly controlled patients who remained on oral agents was also studied. After 4 weeks of insulin treatment, there were significant improvements in mental health, role-emotional, role-physical (all P < 0.05) and vitality (P < 0.01) domains of the short form health survey (SF-36), and also in the diabetes treatment and satisfaction questionnaire (DTSQ) and geriatric depression scale (both P < 0.01) compared to baseline. After 12 weeks, the improvements in mental health, social functioning and vitality (P < 0.01 for all domains), and in the DTSQ were sustained. Carer strain was lower at 4 weeks. No changes in outcomes were seen in the comparison group. In selected elderly Type 2 diabetic patients, insulin treatment is associated with significant improvements in well-being, treatment satisfaction and mood, even without significant improvements in glycaemic control and without increase in carer strain. The SF-36 and DTSQ are sensitive to the benefits of the changes in the treatment for these patients. (C) 2002 Elsevier Science Ireland Ltd. All rights reserved.
