A study from Italy has found that elderly diabetes patients using self-mixed insulin commonly make errors in the measurement of their insulin. The researchers recommend using premixed insulin to reduce difficulty and increase accuracy of insulin injections. The report of the study is published in Diabetes Care, November 1992.
Results of the study revealed that insulin preparation among elderly subjects was highly inaccurate, probably due to impaired vision and motor functions. The researchers speculate that using premixed insulin could improve glycemic control for elderly diabetes patients by improving the accuracy of insulin delivery.
The quality of glycemic control was found to be equal for both self-mixed and premixed insulin. At the end of the study, patients showed a preference for premixed insulin because it was relatively easier to use.
