Insulin Bolus Calculator: Lessons Learned from Institutional Experience

Abstract

Insulin bolus calculators have proven effective in improving glycemia and patient safety. Insulin calculators are increasingly being implemented for inpatient hospital care. Multidisciplinary teams are often involved in the design and review of the efficacy and utilization for these calculators. At times, unintended consequences and benefits of utilization are found on review. Integration of our insulin calculator into our electronic health record system was a multidisciplinary effort. During implementation, several obstacles to effective care were identified and are discussed in the following manuscript. We describe the barriers to utilization and potential pitfalls in clinical integration. We further describe benefits in patient education, time of insulin administration versus meal delivery, variations in insulin bolus for ketone correction, variation in care, and maximum bolus administration. Sharing lessons learned from experiences using electronic insulin calculator order sets will further our goals of improved patient care in the hospital setting.
