Patients with diabetes make up a disproportionate percentage of those admitted to the hospital, because of mor e fre quent hospi talizations for car dio vasc ular , cer ebr ovas cul ar, and peripheral vascular disease; renal failure; infections; and lower extremity am- putations. While landmark studies in the 1990s demonstrated reduced micro- and macrovascu lar events with aggre ssive diabetes cont rol in outp atien ts [2–5], only recently has evidence supported aggressive inpatient diabetes con- trol. Historically, inpatient hyperglycemia has been viewed as an expected outcome of a stressful illness among glucose-intolerant individuals. Physi- cians have traditionally delegated inpatient diabetes management as second- ary in importance to the acute illness, often instituting sliding scale insulin as the only means to addr ess hype rglycemia [6]. Ho wever, diabetes ha s no w been identied as an independent risk factor for adverse inpatient outcomes [7,8]. Ran domize d stu die s have also shown that aggres sive tre atment of hyperglyc e- mia in the intensi ve care unit set ting leads to redu ced morb idity and mortal ity [9–11]. This arti cl e wi ll re vi ew the adverse eects of hype rglyc emia among hos- pitalized patients, and provide treatment recommendations.
