Evaluation of the psychosocial impact of the MiniMed variable-rate implantable insulin pump

Abstract

We examined the psychosocial impact of treatment with an implantable insulin pump among persons with insulin-dependent diabetes mellitus (IDDM). Of specific interest was whether use of the MiniMed implantable insulin pump (MIP) resulted in changes in functional status, performance of diabetes self-care behavior, psychologic symptoms, and perceived level of stress. From a sample of 36 patients with IDDM, 10 persons were randomly selected to receive the MIP, while the remaining 26 served as control subjects. Additionally, a nonrandom sample of three MIP recipients from an additional site were included in the MIP group. At regular assessment intervals, all participants completed self-report questionnaires regarding psychosocial functioning and monitored blood glucose levels. After 4 months of MIP use, MIP recipients did not significantly differ from control subjects on any measure of psychosocial functioning; however, MIP use did have an impact on diabetes self-care. The MIP users monitored their blood glucose levels more frequently and had lower average blood glucose levels than control subjects. Additional follow-up is needed to determine the long-term psychosocial impact of implantable insulin pump therapy.
