Objective
Evidence-based practices are not consistently applied in the intensive care unit (ICU). We sought to determine if nurse-led remote screening and prompting for evidence-based practices using an electronic health record could impact ICU care delivery and outcomes in an academic medical center.
Design
Single-center, before-after evaluation of a quality improvement project.
Setting
Urban, academic medical center in the mid-Atlantic United States with 8 subspecialty ICUs and 156 ICU beds.
Patients
Adult patients admitted to the ICU between January 1, 2011 and August 31, 2012.
Intervention
Beginning on July 25, 2011, trained ICU nurses screened all ICU patients for selected evidence-based practices on a daily basis. The screening was conducted from a remote office, facilitated by the electronic health record. Selected practices included compliance with a ventilator care bundle, assessment of appropriateness of indwelling venous and urinary catheters, and concordance between sedation orders and documented level of sedation. When gaps were observed they were communicated to the point-of-care bedside nurse via telephone, page or facsimile.
Measurements and Main Results
14,823 unique patients were admitted during the study period. We excluded 1,546 patients during a 2-month run-in period from July 1, 2011 to August 31, 2011, resulting in 4,339 patients in the 6-month pre-intervention period and 8,938 patients in the 12-month post-intervention period. Compared to patients admitted in the pre-intervention period, patients admitted in the post-intervention period were more likely to receive sedation interruption (incidence rate ratio: 1.57, 95% CI: 1.45 – 1.71) and a spontaneous breathing trial (incidence rate ratio: 1.24, 95% CI: 1.20 – 1.29). Hospital acquired infection rates were not different between the two periods. Adjusting for patient characteristics and illness severity, patients in the post-intervention period experienced shorter duration of mechanical ventilation (adjusted reduction: 0.61 days, 95% CI: 0.27 – 0.96, p <0.001), shorter ICU length of stay (adjusted reduction: 0.22 days, 95% CI: 0.04 – 0.41, p=0.02), and shorter hospital length of stay (adjusted reduction: 0.55 days, 95% CI: 0.15 – 0.93, p=0.006). In-hospital mortality was unchanged (adjusted odds ratio: 0.96, 95% CI 0.84 – 1.09, p=0.54). The results were robust to tests for concurrent temporal trends and coincident interventions.
Conclusions
A program by which nurses screened ICU patients for best-practices from a remote location was associated with improvements in the quality of care and reductions in duration of mechanical ventilation and length of stay, but had no impact on mortality.
