Diabetes Disaster Averted #64: Long-Time Insulin Users Still Make Errors

Dec 18, 2011

I recently met with a patient to confirm his understanding of a correction schedule based on his pre-meal blood glucose. He’d been on insulin for more than 12 years.  On the 70/30 correction schedule, he and his wife were both able to find the right doses based on the BG values I gave them for morning and evening blood glucose levels….

I then said, “I’m sure you’ll think I’m silly for asking you to show me how to draw up the dose since you’ve been on insulin for so long but….” However, instead of drawing the dose to the top of the plunger he was only pulling the dose down to the bottom of the plunger which was 8 units less than the correct dose would have been.  Both he and his wife said they had NEVER been taught how to draw up the insulin and nobody had ever asked them to show how they were drawing it up.

Needless to say, his need for increased insulin was not as much as the provider thought as he’d been taking 8 units less than what had been prescribed.

Lesson Learned:

Never assume that a long-time insulin-using patient knows the correct way to dose and inject.
