Inpatient hyperglycaemia improvement quality program

Suggested Canadian Standards for Perioperative/Periprocedure Glycemic Management in Patients With Type 1 and Type 2 Diabetes

OBJECTIVES

The goal of this quality initiative was to develop consensus standards for glycemic management of patients with diabetes who undergo surgical procedures in Canada.

METHODS

A modified Delphi method was used to gather broad stakeholder input and arrive at a consensus for perioperative/periprocedure diabetes management.

RESULTS

Glycemic management standards were developed for the following categories: Organization of Care; Preoperative Assessment; Immediate Preoperative and Intraoperative; Postanesthesia Care Unit or Recovery Room; Postoperative Period; and Transition to Outpatient Care.

CONCLUSIONS

It is anticipated these standards will serve as a basis to develop clinical tools to support the recommendations.

Hypoglycemia- simplifying the ways to predict an old problem in the general ward

OBJECTIVE

To examine the association between hypoglycemic events and inpatient and outpatient mortality rates, and to characterize the profile of patients with diabetes who develop hypoglycemia during hospitalization in order to identify risk factors and potentially avoid it.

RESEARCH DESIGN AND METHODS

This retrospective cohort study analyzed data of 3410 patients with diabetes hospitalized during 2012. The associations among biochemical measures, severity of hypoglycemia, inpatient length of stay, and mortality during hospitalization, one month and within one year after discharge were evaluated.

RESULTS

Hypoglycemia was observed in 18.5% (633/3410) of patients with diabetes, 83% (529/633) with mild/moderate hypoglycemic values. Adjusted for age and sex, the 30-day mortality rate after discharge was higher in the group with mild/moderate hypoglycemia (HR = 1.749, CI 1.288-2.374, p < 0.001) and in the group with severe hypoglycemia (HR = 3.390, CI 2.332-6.100, p < 0.001). The mortality rate at the one-year follow-up was higher in the group with mild/moderate hypoglycemia (HR = 1.749, CI 1.288-2.374, p < 0.001) and in the group with severe hypoglycemia (HR = 3.390, CI 2.332-6.100, p < 0.001). In multivariate analysis, hemoglobin and albumin below normal values, and creatinine values above the upper limit were strongly associated with hypoglycemia (OR 1.35, 95%CI 1.1-1.6, p < 0.03; OR 1.6, 95%CI 1.33-1.89, p < 0.001; OR 1.3, 95%CI 1.08-1.55, p < 0.04, respectively).

CONCLUSIONS

Hospitalized patients with diabetes and low hemoglobin, low albumin or high creatinine levels are at increased risk of developing significant hypoglycemia. Identifying accurate high-risk factors in order to intervene early and efficiently can prevent life-threatening complications.

High Glucose Variability in Hospitalized Patients with Type 1 Diabetes Mellitus

BACKGROUND

Glucose variability (GV) has been increasingly (or more extensively) studied in patients with type 1 diabetes (T1D) in the ambulatory setting; limited data exist on GV in hospitalized patients with T1D.

MATERIALS AND METHODS

Retrospective single center cohort study, we analyzed in-hospital glucose measurements to assess GV in 736 hospitalized patients in different units over a consecutive 5-year period of time. GV was assessed by mean blood glucose (BG), Average daily risk range (ADRR), high BG index, and low BG index. To place our findings in context, we conducted a systematic review using Cochrane collaboration methodology to critically analyze current published literature on GV in hospitalized T1D patients.

RESULTS

Overall, glycemic control was suboptimal with mean BG 183 ± 51.5 mg/dL and mean ADRR 35 with only 16% patients being categorized as low risk (ADRR <20) for hypo or hyperglycemia. Patients admitted in medical units had mean BG of 194.4 ± 42.8 mg/dL (95% CI = 101.2-346.6) and ADRR of 39.4 ± 16 (95% CI = 1.3-118.7), which were higher than the patients admitted in the surgical units (mean BG 168.1 ± 35.7 (95% CI = 74.8-301.8) and mean ADRR (28.8 ± 13.1 [95% CI = 0.3-93.1]). For the systematic review, initial search yielded 2336 studies for screening, however, none of them had data specific for T1D.

CONCLUSION

GV is high in hospitalized T1D patients admitted at our tertiary care center. Review of the literature shows paucity of data regarding GV in hospitalized patients with T1D.

Long-term glycaemic control (HbA1c), not admission glucose, predicts hospital re-admission in diabetic patients

BACKGROUND

Diabetic patients are commonly hyperglycaemic on presentation. Admission hyperglycaemia is associated with adverse outcomes, particularly prolonged hospitalisation. Improving inpatient glycaemia may reduce length of hospital stay (LOS) in diabetic patients.

AIMS

To determine whether in-hospital recognition and treatment of admission hyperglycaemia in diabetic patients is associated with reduced LOS.

METHODS

Medical records were reviewed from 1 November 2011 to 31 May 2012 for 162 diabetic patients admitted with a blood glucose level (BGL) ≥11.1mmol/L. In-hospital outcomes were compared. Stepwise multiple regression was used to evaluate factors contributing to LOS.

RESULTS

Compared to the untreated individuals (n=67), hyperglycaemia treatment (n=95) was associated with a longer LOS (median eight vs. four days, p<0.01), higher HbA1c (9.0 vs. 7.3 per cent, p<0.01), more infections (50 vs. 25 per cent, p<0.01), and more patients with follow-up plans (35 vs. 10 per cent, p<0.01). Higher HbA1c was significantly related to more follow-up (ρs=0.30, n=110, p<0.01) with a trend to lower re-admission in those with follow-up plans (ρs=-1.41, n=162, p=0.07).

CONCLUSION

Recognition and treatment of admission hyperglycaemia in diabetic patients was associated with longer LOS than if untreated. Contributory factors to LOS include: illness severity, infections, and higher HbA1c. Although follow-up plans were few (27 per cent) for diabetic patients with hyperglycaemia, it was significantly more likely in those with higher HbA1c. Diabetic patients' complexities require timely multidisciplinary team involvement. Improved follow-up care, particularly for hospitalised diabetic patients identified to have chronically poor glycaemic control, may help prevent future diabetic patient re-admissions.
