At the start of the study, participants had average A1c readings of 9.1 percent, indicating poorly controlled blood sugar with an increased risk of serious complications.
After two years of follow-up, most patients still had poorly controlled blood sugar. People using the pumps achieved average A1c reductions of 0.85 percentage points, compared with 0.42 percentage points with multiple daily injections, researchers report in the BMJ.
Once researchers accounted for other factors that can influence blood sugar such as age, sex and treatment center, the difference in A1c for pump versus injection patients was too small to rule out the possibility that it was due to chance.
“I think the take-home message for patients is that pumps won’t do the job for you,” Gale said by email. “They are not for everyone, and many people can do just as well on multiple injections.”
