Results show that a stricter target of 80-110 mg/dL is not superior to 110-140 mg/dL in mortality and morbidity rate….
Hyperglycemia is common among hospitalized patients; an intensive goal in hyperglycemia management of blood glucose is 80-110 mg/dL Studies have shown increased rates of hypoglycemia without morbidity and mortality with the blood glucose of 80-110 mg/dL
The goal of this retrospective study was to examine the glucose outcomes for the first 3 days after surgery and 30 days cardiac outcomes before and after insulin protocol with a glycemic target goal of 110-140 mg/dL instead of 80-110 mg/dL. A total of 1,325 participants data were collected using the Northwestern Medicine Enterprise Data Warehouse. The fasting and pre-meal targets during subcutaneous treatment were 80-150 mg/dL for the 80-110 group and 110-180 mg/dL for the 110-140 group.
Fewer participants in the 110-140 mg/dL group experienced moderate hypoglycemia of blood glucose less than 70 mg/dL (177 vs 73, P=0.04). Though severe hypoglycemia occurred in one patient in the 80-110 group and three in the 110-140 group. The 110–140 group had higher mean postoperative BG levels compared to the 80-110 group during the intravenous insulin infusion (141 ± 15 vs. 121 ± 15 mg/dL, P < 0.001) and the subcutaneous insulin period (134 ± 24 vs. 130 ± 23 mg/dL, P < 0.001), and for 3 days postoperatively (141 ± 17 vs. 127 ± 15 mg/dL, P < 0.001).
In conclusion, the results suggest that a higher glycemic target of 110-140 mg/dL was associated with significantly fewer cases of hypoglycemia. There were no significant differences in outcomes such as mortality and morbidity between the two groups.
- A stricter target of 80-110 mg/dL is not superior to 110-140 mg/dL in mortality and morbidity rate.
- A glycemic target of 110-140 mg/dL is safer due to fewer instances of hypoglycemia.
- Similar mean glucose values in both groups.
