OBJECTIVE: To determine the relationship between intensivist staffing and select process-based quality indicators in the intensive care unit. RESEARCH
DESIGN: Retrospective cohort study in 29 academic hospitals participating in the University HealthSystem Consortium Mechanically Ventilated Patient Bundle Benchmarking Project.
Patients: 861 adult patients receiving prolonged mechanical ventilation in an intensive care unit.
RESULTS: Patient-level information on physician staffing and process-of-care quality indicators were collected on day 4 of mechanical ventilation. By day 4, 668 patients received care under a high intensity staffing model (primary intensivist care or mandatory consult) and 193 patients received care under a low intensity staffing model (optional consultation or no intensivist). Among eligible patients, those receiving care under a high intensity staffing model were more likely to receive prophylaxis for deep vein thrombosis (risk ratio 1.08, 95% CI 1.00 to 1.17), stress ulcer prophylaxis (risk ratio 1.10, 95% CI 1.03 to 1.18), a spontaneous breathing trial (risk ratio 1.37, 95% CI 0.97 to 1.94), interruption of sedation (risk ratio 1.64, 95% CI 1.13 to 2.38) and intensive insulin treatment (risk ratio 1.40, 95% CI 1.18 to 1.79) on day 4 of mechanical ventilation. Models accounting for clustering by hospital produced similar estimates of the staffing effect, except for prophylaxis against thrombosis and stress ulcers.
CONCLUSIONS: High intensity physician staffing is associated with increased use of evidence-based quality indicators in patients receiving mechanical ventilation. | | Language | eng | | Pub Type(s) | Journal Article
