Little is known about the 1-year short-term mortality rate following hospital admissions with severe hypoglycemia. This study aimed to determine the factors associated with increased 1-year mortality rate following hospitalization in diabetes patients admitted with severe hypoglycemia to the Singapore General Hospital.Clinical, biochemical, and 1-year mortality data from diabetes patients who were admitted with severe hypoglycemia in the year 2014 were extracted from institutional medical records. Patients who passed away during the episode of admissions with severe hypoglycemia were excluded from the analysis. The clinical and biochemical factors between patients who survived and those who did not survive within 1 year following admission were compared using logistic regression analysis.Three hundred and four patients (181 female and 123 male) were admitted with severe hypoglycemia in 2014, and the mean capillary blood glucose on admission was 2.3 ± 0.7 mmol/L. Sixty-three (20.7%) patients died within 1-year post-discharge from the hospital. Compared with patients who survived 1-year post-discharge from the hospital, non-survivors were older (69.3 ± 11.0 vs 75.5 ± 11.2 years, p .001), had longer lengths of stay (LOS) (5.0 ± 7.4 vs 9.0 ± 12.8 days, p = .02), and had a higher Charlson Comorbidity Index (CCI) (4.1 ± 1.9 vs 5.9 ± 2.4, p .001). Factors associated with increased 1-year mortality risk were age (odds ratio [OR] = 1.06; 95% confidence interval [CI] = 1.03-1.09, p .01), LOS in hospital (OR = 1.01; 95% CI = 1.01-1.08, p .01), and CCI (OR = 1.51; 95% CI = 1.31-1.75, p .01), respectively.Older diabetes patients with more comorbidities and longer LOS were at increased risk of dying within a year of discharge after hospitalization with severe hypoglycemia. Admission with severe hypoglycemia has important prognostic implications. Healthcare professionals should address hypoglycemia and other health issues during the hospital admissions.

Summary Severe hypoglycaemia carries considerable morbidity and potential mortality. We aim to elucidate the factors which were associated with a prolonged length of stay (LOS) among patients with diabetes who were admitted to the hospital with severe hypoglycaemia. Three hundred and four patients were included in the analysis, with a mean age of 70.6 ± 11.3 years, mean glycated haemoglobin of 6.9 ± 1.3% and median LOS of 3 days. Patients with a LOS >3 days had significantly higher Charlson Comorbidity Index (CCI) (4.9 ± 2.1 vs 4.1 ± 2.1, P

To implement an inpatient glucose management (IGM) programme in the general medical wards and evaluate its clinical efficacy.Consecutive patients admitted to selected medical wards over a 12-month period were included in the IGM programme. All patients with ≥3 capillary blood glucose (CBG) readings (10.0 mmol/L and/or4.0 mmol/L) over a 24-hour period were identified electronically. A multidisciplinary team of diabetes care providers would provide specialist input to these patients. The control group comprised of consecutive patients admitted over the preceding 12 months. Outcome glucose measures include mean in-hospital glucose (MHG), mean patient-day glucose (MDG), proportion of CBG readings at predefined cut-offs and length of stay (LOS).Both the MHG and MDG were significantly lower following intervention (10.0±2.4 mmol/L vs 11.2±2.6 mmol/L, P.001; 10.0±2.3 mmol/L vs 11.2±2.6 mmol/L, P.001, respectively). Prevalence of hyperglycaemic events, defined by CBG10.0 mmol/L, was significantly lower at 36.5% versus 51.6% (P.001). Hypoglycaemic events of CBG4.0 mmol/L remained infrequent at1.0% before and after IGM programme. A greater proportion of glucose readings was controlled within the target range of 4.0-10.0 mmol/L (62.6% vs 47.6%, P.001). With the IGM programme in place, more patients received scheduled CBG monitoring, and a significant shortening of mean LOS by 3.2 days was observed (P=.02).The IGM programme was effective in improving inpatient glycaemic monitoring and control in the general medical wards, with a significant reduction in LOS observed. These demonstrated the programme's potential to enhance quality and efficiency of patient care.
