Benefits and Risks of Tight Glucose Control in Critically Ill Adults

2medical:26.9%vs29.7%;RR,0.92;95%CI,0.82-1.04;or3medical-surgical:26.1% vs 27.0%; RR, 0.95; 95% CI, 0.80-1.13). Tight glucose control was not associated with significantly decreased risk for new need for dialysis (11.2% vs 12.1%; RR, 0.96; 95% CI, 0.76-1.20), but was associated with significantly decreased risk of septicemia (10.9% vs 13.4%; RR, 0.76; 95% CI, 0.59-0.97), and significantly increased risk of hypoglycemia (glucose 40 mg/dL; 13.7% vs 2.5%; RR, 5.13; 95% CI, 4.09-6.43). Conclusion In critically ill adult patients, tight glucose control is not associated with significantly reduced hospital mortality but is associated with an increased risk of hypoglycemia.
