Dashboard elements
| Measures | Denominator/cohort | Numerator/definition | 10th and 90th percentile range of values at ICU level |
| Outcomes | |||
| Mortality at hospital discharge | |||
| Unadjusted mortality | All first ICU admissions, excluding transferred patients | Number of patients in denominator that died at discharge from the hospital | 4.2–11.8% |
| Adjusted mortality | Sum of the predicted hospital mortality of each patient | Observed number of deaths at hospital discharge | 0.66–1.25 |
| Unadjusted mortality of patients transferred from the ward to the ICU (reflects ability of hospital to rescue patients) | Number of patients transferred from the ward to the ICU excluding those transferred to another hospital at discharge. | Of patients in the denominator, those that die at hospital discharge | 8.9–26.2% |
| Mortality at 30 days from admission | |||
| Unadjusted | First ICU admissions for any hospitalisation, assigns patients transferred at discharge to the transferring hospitals | Number of patients in denominator that died at 30 days from hospital admission | 7.1–13.8% |
| Adjusted | Sum of the predicted 30-day mortality of each patient | Observed number of deaths at 30 days from admission | 0.76–1.19 |
| Throughput | |||
| Observed minus predicted length of stay | COHORT: Survivors to 32 days, LOS truncated to 32 days for those with LOS >32 days | CALCULATION: Sum of the Observed minus predicted length of stay for each patient divided by the total number of patients | −0.99 to 0.57 days |
| Mean Length of stay | First admissions to the ICU | Date and time of discharge minus date and time of admission divided by 24 h to convert to days | 2.14 to 3.93 days |
| Hospital acquired infections | |||
| Central line associated blood stream infections | Number of central line days where each patient can have a maximum of 1 line day each day, CDC central line definition used | Number of central line infections using CDC definitions | 0–3.85/1000 line days |
| Ventilator associated pneumonia | Number of ventilator days; counted once daily at the same time | Number of ventilator associated pneumonias using CDC definitions | 0–5.28/1000 vent days |
| Process measures | |||
| Glycaemia management | |||
| Hypoglycemia (cut point 45 mg/dl) | Count of patient days in ICU on hypoglycemic agent per time period | # patient days with a Glucose <cut point among patients included in denominator (on hypoglycemic agent) | 0–1.9% |
| Hypoglycemia (cut point 60 mg/dl) | 1.4–4.7% | ||
| Proportion of patients with mean glucose >180 mg/dl | Total number of patients (PTS) with at least two glucose measurements excluding those admitted with diabetes | # patients with a mean glucose > 180 mg/dl (mean glucose=sum of all glucose meausures in ICU divided by the number of glucose measures) | 11–27.6% |
| Deep venous thrombosis (DVT) pharmacologic prophylaxis | |||
| Mechanical ventilation | # patients with mechanical ventilation ICD-9-CM codes | # PTS in denominator with MD order for heparin, LMW heparin, Agratroban, fondiparinux, or coumadin | 63–93% |
| Operative | # patients with procedure codes (GI surgery, hip fracture/replacement) at high risk for DVT | 53–100% | |
| Non-operative | # patients with primary admission diagnosiscodes for non-operative cases (CHF, COPD, pneumonia, malignancy, acute renal failure, sepsis) at high risk for DVT | 67–89.5% | |
| Adherence to evidence based practices for devices | |||
| Central line insertion | Total number of audits (entered monthly) of central line insertion | Number of times in audits each practice used (chlorhexidine skin prep, femoral site, maximal sterile barriers, bed sized drape) | 89–100% |
| Ventilator | Audited cases of ventilator practices | # times each practice used (HOB> 30°, sedation vacation, spontaneous breathing trial, VTE prophylaxis, SUD prophylaxis) | 64–100% |
| Throughput | |||
| Bed turns | Number of operating beds in the ICU | Number of patients admitted (rolling 12 months) | 45–91 |
| Adjusted bed turnover | The number of operating beds in the ICU | Number of patients admitted (rolling 12 months) time the case severity index | 36–94 |
| Readmissions to the ICU during same hospitalization | All patients admitted to the ICU | Number of patients who return to the ICU after discharge to the ward | 2–26% |
| 30-day readmission rate—all cause | All patients admitted to the ICU (first ICU admission to avoid counting patients twice) | Number of patients in denominator who are admitted to the ICU within 30 days from dischargefrom the hospital | 8.6–14.2% |
