Glycaemic indicators in studies of tight glycaemic control comparing outcomes on general medical wards (this study) with published studies performed in intensive care units19
| Chronic obstructive pulmonary disease patients on general medical wards | Published intensive care unit studies | No of intensive care unit studies using indicator | |
| Safety | |||
| Capillary glucose <2.2 mmol/l (percentage of measurements) | 0.2 | 0.1 (range 0–0.2) | 12 |
| Capillary glucose ≤3.3 mmol/l (percentage of measurements) | 4.1 | 0.3 (range 0.1–2.1) | 7 |
| Efficacy | |||
| Study CBG (mmol/l) | 5.9 (IQR 5.4–6.5) | 6.8 (range 5.7–8.5) | 10 |
| 06:00 CBG (mmol/l) | 4.8 (IQR 4.4–5.8) | 6.5 (range 5.7–8.1) | 5 |
| Percentage of CBG measurements in target range | 40 | 51 (range 29–69) | 11 |
| Percentage of time CBG in target range | 41 | 53 (range 34–96) | 9 |
| Hyperglycaemic index | 1.1 (IQR 0.7–1.6) (threshold 6.5 mmol/l) | 1.0 (IQR 0.9–1.8) (threshold 6.0 mmol/l) | 2 |
| Glycaemic variability (mmol/l) | 2.9 (IQR 2.2–3.3) | 1.7 (IQR 1.3–2.3) | 4 |
| Protocol adherence | |||
| Adherent CBG measurements (%) | 82 | 53 (range 29–98) | 4 |
| Adherent insulin (intravenous) dose adjustments (%) | 89 | 72 (range 56–100) | 4 |
Values are median values for participants (this study) or for studies (ICU).19 The range is minimum—maximum.
