4 Hyperglycemia Is Prevalent at Hospital Admission
38% of all patients at admission have hyperglycemia – Of those patients, nearly one-third have no history of diabetes Hyperglycemia Is Prevalent at Hospital Admission The medical records of 2030 consecutive adult patients admitted to a community hospital in Georgia over a 15-week period (July 1, 1998–October 20, 1998) were reviewed to determine the prevalence of in-hospital hyperglycemia and its impact on survival and functional outcome in patients with and without a history of diabetes. Because 144 patients did not have a blood glucose value, only 1886 patients were eligible for the study. Hyperglycemia was defined as an admission or in-hospital fasting blood glucose level of 126 mg/dL or more, or random blood glucose levels of 200 mg/dL or more on 2 or more occasions. Results on admission indicate that 1168 patients were normoglycemic (62%) and 718 were hyperglycemic (38%). Of those who were hyperglycemic, 223 (31%) did not have a previous history of diabetes. Single-center, retrospective chart review of 1886 patients hospitalized over 15 weeks in a community teaching hospital. Hyperglycemia defined as BG ≥126 mg/dL on admission or while fasting, or random BG ≥200 mg/dL on ≥2 occasions. Umpierrez GE et al.

Of the 4940 patients (30%) with recognized diabetes mellitus (DM), nearly half (2412 patients, 49%) had mean BG >200 mg/dL during the first 24 hours after hospital admission. When the entire hospitalization was considered, 34% of DM patients had mean BG >200 mg/dL, while 61% had mean BG between 110 and 200 mg/dL, and only 5% maintained mean BG <110 mg/dL. Among patients without recognized DM, 8% had mean BG >200 mg/dL during the first 24 hours. When the entire hospitalization was considered, 4% of patients without known DM had mean BG >200 mg/dL, while 65% had mean BG between 110 and 200 mg/dL, and 31% had mean BG <110 mg/dL. <110 >200 <110 >200 Mean BG, mg/dL Kosiborod M, et al.

13 Medical ICU Study Results
In-hospital mortality for patients who were in the ICU and on CII for >3 days was lower (52.5% to 43.0%) - RRR=18.1% P=.009 In-hospital morbidity was lower - Reduction in newly acquired kidney injury - Weaning from mechanical ventilation - Discharge from ICU; discharge from Hospital Hypoglycemia was an independent risk factor for mortality Van den Berghe et al.

On admission, patients were randomly assigned to intensive treatment (IV treatment to maintain blood glucose between mg/dL) or to conventional treatment (IV treatment given only when the blood glucose level >215 mg/dL and tapered when BG <180 mg/dL). The primary outcome of the study was all-cause mortality during hospitalization. A predefined subgroup analysis for patients staying in the ICU for ≥3 days was also performed. Intensive therapy significantly reduced morbidity but not in-hospital mortality. Reductions in morbidity were reflected by a reduction in newly acquired kidney injury, earlier weaning from the ventilator, earlier discharge from the ICU, and earlier discharge from the hospital. For all patients, total ICU and in-hospital mortality were not significantly different. In-hospital: 37.3% in the intensive treatment group died as compared with 40% in the conventional treatment group (P=.33). ICU: 24.2% in the intensive treatment group died compared with 26.8% in the conventional treatment group (P=.31). The predefined subanalysis demonstrated significantly decreased in-hospital mortality and appeared to decrease total ICU mortality among patients with an ICU stay ≥3 days. In-hospital: Among all patients in the hospital, 43% in the intensive treatment group died compared with 52.5% in the conventional treatment group (P=.009). ICU: 31.3% in the intensive treatment group died compared with 38.1% in the conventional treatment group (P=.05). 10 20 30 40 50 60 70 80 90 20 40 60 80 100 100 200 300 400 500 600 Days after admission to ICU Prospective, randomized, controlled study of adult patients admitted to the medical ICU, N= On admission, patients were randomly assigned to intensive treatment or to conventional treatment.

In the NICE-SUGAR study,10 critically ill patients treated in the intensive glucose control group ( mg/dL) were 14% more likely to die (27.5% vs 24.9%) than were those in the conventional glucose control group ( mg/dL).

24 Blood Glucose During Hospitalization and Incidence of Death Within 2 Years
[Svensson.EurHeartJ. 2005/p1260/Fig 2] Lowest blood glucose recorded during hospital stay ≤3.0 mmol/L or 55 mg/dL n+44; 20 deaths mmol/L or mg/dL n=364; 101 deaths ≥6.6 mmol/L or ≥120 mg/dL n=276; 107 deaths ( ) -3.5 -2.5 -1.5 -.5 .5 1.5 2.5 3.5 Referent ( ) This study evaluated the associations between glycometabolic parameters at admission and during hospitalization and 2-year all-cause mortality risk in an unselected cohort of consecutive patients with diabetes admitted for unstable angina or non-Q-wave myocardial infarction to a university hospital during For the 684 patients with blood glucose data during hospitalization available, 44 patients had at least 1 documented hypoglycemic event with glucose documented ≤3.0 mmol/L (≤55 mg/dL), 364 had an intermediate glucose value ( mmol/L or mg/dL), and 276 had persistent hypoglycemia with the lowest glucose documented ≥6.6 mmol/L (or 120 mg/dL). Compared with the intermediate group, both the lowest and the highest groups had significantly higher adjusted 2-year mortality using a model that included on-arrival blood glucose as a covariate (HR, 1.93; 95% CI, ; HR, 1.48; 95% CI, , respectively).

25 Severe Hypoglycemia in Critically Ill Patients Associated With Increased Risk of Mortality
60 50 40 Mortality Rate, % 30 20 10 This study was a retrospective database review, including a case-control analysis that matched each patient with severe hypoglycemia with 3 controls. It included 102 patients with at least 1 episode of severe hypoglycemia extracted from a series of 5365 medical, surgical, and cardiac patients admitted consecutively between October 1, 1999, and June 15, A program of tight glycemic control was implemented on February 1, 2003; 2666 patients were treated before and 2699 after this date. Multivariable logistic regression analysis identified diabetes, septic shock, renal insufficiency, mechanical ventilation, severity of illness, and treatment in the tight glycemic control period as independent risk factors for the development of severe hypoglycemia (defined as glucose <40 mg/dL). Mortality was 55.9% among the 102 patients with severe hypoglycemia and 39.5% among the 306 controls (P=.006). Multivariable logistic regression analysis identified severe hypoglycemia as an independent predictor of mortality for the entire cohort (odds ratio, 2.28; 95% CI, ; P=.008). SH Controls No SH Severe hypoglycemia (<40 mg/dL) was associated with an increased risk of mortality (OR, 2.28; 95% CI, ; P=.0008) Krinsley JS, Grover A. Crit Care Med. 2007;35(10):

27 Mean Glucose & In-Hospital Mortality in 16,871 Patients with AMI
(Reference: Mean BG mg/dl) Investigators evaluated 16,871 acute myocardial infarction (MI) patients hospitalized from January 2000 to December Using logistic regression models and C indexes, 3 metrics of glucose control (mean glucose, time-averaged glucose, hyperglycemic index), each evaluated over 3 time windows (first 24 hours, 48 hours, entire hospitalization), were compared with admission glucose for their ability to discriminate hospitalization survivors from nonsurvivors. Models were then used to evaluate the relationship between mean glucose and in-hospital mortality. In unadjusted analysis, higher mean hospitalization glucose was strongly associated with higher in-hospital mortality. As shown in the figure on the left, when mean hospitalization glucose was analyzed in increments of 10 mg/dL, there was a clear J-shaped relationship between glucose values and mortality rates. Although in the normal glucose range, patients without recognized diabetes had a lower mortality rate than patients with diabetes, their risk increased much more steeply at higher glucose levels, surpassing the risk of patients with diabetes at approximately 130 mg/dL. After multivariable adjustment, the nature of these relationships persisted. As shown in the figure on the right, higher mean hospitalization glucose continued to be strongly associated with higher in-hospital mortality. There was a statistically significant, gradual increase in the odds of in-hospital mortality with each 10-mg/dL incremental rise in mean hospitalization glucose levels above the threshold of 120 mg/dL. The odds of death associated with higher mean glucose rose steeply in patients without recognized diabetes once mean glucose levels exceeded 120 mg/dL. Measures of persistent hyperglycemia were better predictors of mortality than was admission glucose. Mean hospitalization glucose appears to be the most practical metric of hyperglycemia-associated risk in patients with acute MI. Kosiborod M et al. Circulation 2008:117:1018

29 Strategies for Preventing Hypoglycemia in the ICU
[Devos.CurrOpin ClinNutr.2007/p206/ c2/line 40-46, p207/ c1/line 1-4] Better protocols and systems to implement insulin protocols Less aggressive BG targets (AACE/ADA Guidelines) Improved glucose monitoring devices to analyzed frequent and accurate real-time CGM Inpatient hyperglycemia teams SO, WHAT CAN we DO?

30 AACE/ADA Recommended Target Glucose Levels in ICU Patients
ICU setting: Starting threshold of no higher than 180 mg/dL Once IV insulin is started, the glucose level should be maintained between 140 and 180 mg/dL Lower glucose targets ( mg/dL) may be appropriate in selected patients   Targets <110 mg/dL or >180 mg/dL are not recommended Based on the high rate of hypoglycemia and no difference in mortality in major trials, and the results of NICE –SUGAR that reported increased mortality… NEW TASK FORCE. The slide shows the recommendations for target glucose levels in critically ill patients in the intensive care setting, which were released on May 8, 2009, by the American Association of Clinical Endocrinologists and the American Diabetes Association, and published online in the June issues of Endocrine Practice and Diabetes Care. They include the following: Insulin therapy should be initiated for treatment of persistent hyperglycemia, starting at a threshold of no greater than 180 mg/dL. Once insulin therapy has been started, a glucose range of 140 to 180 mg/dL is recommended for the majority of critically ill patients. Intravenous insulin infusions are the preferred method for achieving and maintaining glycemic control in critically ill patients. Validated insulin infusion protocols with demonstrated safety and efficacy, and with low rates of occurrence of hypoglycemia, are recommended. With IV insulin therapy, frequent glucose monitoring is essential to minimize the occurrence of hypoglycemia and to achieve optimal glucose control.

31 AACE/ADA Target Glucose Levels in Non–ICU Patients
Non–ICU setting: Premeal glucose targets <140 mg/dL Random BG <180 mg/dL To avoid hypoglycemia, reassess insulin regimen if BG levels fall below 100 mg/dL Occasional patients may be maintained with a glucose range below and/or above these cut-points For the majority of noncritically ill patients treated with insulin, the premeal blood glucose (BG) target should generally be less than 140 mg/dL in conjunction with random BG levels less than 180 mg/dL, provided these targets can be safely achieved. To avoid hypoglycemia, consideration should be given to reassessing the insulin regimen if BG levels decline below 100 mg/dL. Modification of the regimen is necessary when BG values are <70 mg/dL, unless the event is easily explained by other factors (such as a missed meal). More stringent targets may be appropriate in stable patients in whom tight glycemic control was achieved previously. Less stringent targets may be appropriate in terminally ill patients or patients with severe comorbidities. Hypoglycemia is defined as any BG level <70 mg/dL. Severe hypoglycemia in hospitalized patients has been defined by many clinicians as BG <40 mg/dL, although this value is lower than the approximate 50 mg/dL level at which cognitive impairment begins in normal persons. Scheduled subcutaneous administration of insulin, with basal, nutritional, and correction components, is the preferred method for achieving and maintaining glucose control. Prolonged treatment with sliding-scale insulin as the sole regimen is discouraged. Noninsulin antihyperglycemic agents are not appropriate in most hospitalized patients who require treatment for hyperglycemia.

42 Computer-Guided Vs. Standard Column-Based Insulin Regimens
Study Aim: To determine differences in glycemic control between treatment with a computer-guided algorithm (Glucommander) and a standard paper-form algorithm in critically ill patients in the ICU Design: Multi-center, prospective, randomized trial in hyperglycemic patients admitted to a medical ICU Primary outcome: Differences in BG control Secondary outcomes: Number of hypoglycemic (BG <60 mg/dL and < 40 mg/dl) and hyperglycemic events (BG >200 mg/dL), ICU and hospital length of stay To investigate if “better or different algorithms” may not be the answer… we recently completed a Comparison study of Insulin Infusion Protocols in the ICU: Computer-Guided (Glucommander) Vs. Standard Column-Based (paper-form) Insulin Regimens. Presented at the ADA 2008 meeting. Newton CA et al. Diabetes 57 (Suppl. 1) 136A, 2008.

47 Events Triggering Hospital Hypoglycemia
Transportation off ward, causing meal delay Failure to measure blood glucose before insulin doses New NPO status Interruption of IV dextrose therapy Total parenteral nutrition Enteral feedings Continuous venovenous hemodialysis NON_ICU The slide lists events that can trigger in-hospital hypoglycemia. All of the events, except for failure to measure blood glucose before insulin doses, result from decreased caloric intake related to illness or hospital routine. Braithwaite SS, et al. Endocr Pract. 2004;10(suppl 2):89-99. Braithwaite SS, Buie MM, Thompson CL, et al. Hospital hypoglycemia: not only treatment but also prevention. Endocr Pract. 2004;10(suppl 2):89-99.

48 Features Increasing the Risk of Hypoglycemia in an Inpatient Setting
Advanced age Renal failure Liver disease Concurrent illness (cerebral vascular accident, congestive heart failure, shock, sepsis) Ventilator use Concurrent medications (-blockers, quinolones, epinephrine) Among the patient risk factors for hypoglycemia are advanced age, renal failure, liver disease, concurrent illness (eg, cerebral vascular accident, congestive heart failure, shock, sepsis), ventilator use, and use of concurrent medications (eg, β-blockers, quinolones, steroids, epinephrine).

49 Benefits of a Nurse-Mandated Protocol
Title Subtitle Benefits of a Nurse-Mandated Protocol All patients are screened and treated the same way Standardization can be achieved Modification of the protocols can easily be done based on outcomes and analysis of the data

50 Patient Presents With Hyperglycemia
Title Subtitle Patient Presents With Hyperglycemia Previously diagnosed DM Diabetic ketoacidosis or hyperglycemic crisis follow DKA protocol No previous diagnosis of DM and BG > 140 mg/dL Modification of therapy to keep BG at goal BG is > 110 mg/dL for a critically ill patient; notify physician for initiation of IV insulin therapy Begin BG testing BG is > 140 mg/dL for noncritically ill patient, notify physician for initiation of subcutaneous therapy All patients with hyperglycemia should have an HbA1C drawn to aid in transition and discharge therapy

51 Methods of Screening for Hyperglycemia
Title Subtitle Methods of Screening for Hyperglycemia Finger stick blood glucose on admission or use of the glucose done on the biochemical profile If glucose >110 mg/dL fasting or >140 mg/dL random, place in appropriate protocol and continue monitoring Draw Hemoglobin A1C for help in deciding who needs transition from IV to SC insulin and what treatment is needed at home, including insulin. Hyperglycemia in Patients With Undiagnosed Diabetes New hyperglycemia was defined as an admission or in-hospital fasting glucose level of 126 mg/dL (7 mmol/L) or more or a random blood glucose level of 200 mg/dL (11.1 mmol/L) or more on 2 or more determinations. Hyperglycemia was present in 38% of patients admitted to the hospital, of whom 26% had a known history of diabetes, and 12% had no history of diabetes before admission. Newly discovered hyperglycemia was associated with a higher in-hospital mortality rate (16%) compared with patients with a history of diabetes (3%) and patients with normoglycemia (1.7%; both P < 0.01). In addition, new hyperglycemic patients had longer hospital stays and a higher admission rate to an intensive care unit, and were less likely to be discharged to home, frequently requiring transfer to a transitional care unit or nursing home facility. The results indicate that in-hospital hyperglycemia is a common finding and represents an important marker of poor clinical outcome and mortality in patients with and without a history of diabetes. Patients with newly diagnosed hyperglycemia had a significantly higher mortality rate and a lower functional outcome than patients with a known history of diabetes or normoglycemia. 1.

Blood glucose levels significantly improved in patients who had failed sliding-scale insulin delivery and were switched to the basal-bolus regimen. With the BG target of <140 mg/dL, 66% (43 patients) in the basal-bolus group reached the target, while only 38% (25 patients) in the sliding-scale insulin delivery group met this goal. Fourteen percent (9 patients) of the patients treated with sliding-scale insulin delivery remained severely hyperglycemic, defined as BG >240 mg/dL, despite dose maximization. Glycemic control improved in these patients once they were switched to the basal-bolus regimen. Two patients in each group had hypoglycemia (defined as BG <60 mg/dL). No cases of severe hypoglycemia (defined as BG <40 mg/dL) were reported. Days of Therapy Persistent hyperglycemia (BG>240 mg/dl) is common (15%) during SSI therapy Umpierrez GE, et al.

This multicenter, prospective, open-label, randomized study enrolled 130 nonsurgical, insulin-naïve patients with a known history of diabetes for >3 months, admitted to medical general services with a blood glucose level between 140 and 400 mg/dL. Patients were randomly assigned to receive either sliding-scale regular insulin (SSRI; n=65) 4 times daily or a basal-bolus regimen with insulins glargine and glulisine (n=65). The goal of insulin therapy was to maintain fasting and premeal blood glucose levels <140 mg/dL while avoiding hypoglycemia. Compared with the basal-bolus group, patients who received sliding-scale insulin delivery had higher mean fasting glucose (165 ± 41 vs 147 ± 36 mg/dL, respectively, P<.01), mean random glucose (189 ± 42 vs 164 ± 35 mg/dL, respectively, P<.001), and mean glucose (193 ± 54 vs 166 ± 32 mg/dL, respectively, P<.001) during the hospital stay. The overall BG difference between treatment groups was 27 mg/dL (P<.01), with a mean daily BG difference ranging from 23 to 58 mg/dL during days 2 through 6 of therapy (P<.01). aP<.05.
