  • Rates shown as events per 1,000 person-months. Multiply by 12 for annual rates.

  • *

    * RRs postpump/prepump. Ratios <1.0 indicate lower risk compared with postpump.

  • ED visits comprised DKA (n = 1), site infections (n = 4), hypoglycemic events (n = 11), and other events (n = 26).

  • At 14 visits, a patient(s) reported two events during the preceding interval. At one visit, a patient reported three events during the preceding interval.
