Aims The objective of this study was to examine the relationship between measures of coordinated insulin delivery and capillary blood glucose (CBG) levels among hospitalized patients and to assess nurse perceptions of insulin administration. Methods Hospitalized patients (n = 451) receiving rapid acting insulin analog (RAIA) using carbohydrate counting were retrospectively analyzed. Nurses (n = 35) were asked to complete an 18-item anonymous survey assessing perception of RAIA dosing. Results The median time from breakfast CBG to RAIA dose was 93 (IQR 57-138) min. There was no association between timeliness measures and mean CBG at lunch or dinner. Hypoglycemia was rare (N = 2). More than half (54%) of nurses were confident all of the time in determining the correct dose of RAIA, though none were confident in administering it on time. The majority of nurses perceived an electronic dosing calculator and a patient reminder to notify the nurse at the end of the meal favorably. Conclusions The data demonstrate suboptimal coordination of CBG monitoring and insulin doses using a flexible meal insulin dosing strategy, though there was minimal impact on glycemic control. Nurses reported high confidence in the ability to calculate the correct insulin dose but not in the ability to administer it on time.
