Effectiveness and efficiency of intensive care medicine: variable costs in different diagnosis groups
Abstract
To establish the effectiveness of ICU treatment and the efficiency in the use of resources in patients stratified according to 10 diagnosis and two levels-of-care. To propose strategies aimed at reducing costs and improving efficiency in each patient group. Multicentre prospective observational study. ICUs enrolled two cohorts of up to 10 consecutive patients with ICU stay >/= 48 h. Each with one of these diagnoses: trauma, brain-trauma, brain-hemorrhage, stroke, acute-on-chronic-obstructive-pulmonary disease, lung-injury/acute respiratory distress syndrome, heart failure, and scheduled/unscheduled abdominal surgery. The presence of active-life support divides high from low level-of-care treatments. Variable ICU costs were collected daily (bottom-up) for 21 days. We evaluated effectiveness (hospital survival) and efficiency (hospital-survivors variable-cost as a ratio of overall cost). Forty-two Italian general ICUs recruited 529 patients in 5 months. Mean ICU variable-costs significantly differed with diagnosis and level-of-care. Costs were positively affected by ICU length-of-stay, by duration of active-treatment. Outcome variably influenced costs. Medians of variable-costs per patient (1715 Euro) and patient-groups efficienc...Continue Reading
