A Johns Hopkins-led collaborative project involving 56 ICUs at 38 hospitals in Maryland and Pennsylvania from October 2012 to March 2015 successfully reduced rates of ventilator-associated events (Rawat 2017). The quarterly mean ventilator-associated event rate significantly decreased from 7.34 to 4.58 cases per 1,000 ventilator-days after 24 months of implementation, a 38% reduction. Infection-related ventilator-associated complications decreased from 3.15 to 1.56 per 1,000 ventilator-days. Even more impressive was the reduction in rates of possible and probable ventilator-associated pneumonia, which decreased from 1.41 to 0.31 cases per 1,000 ventilator-days, a 78% reduction.
Like many of the collaborative projects led by Johns Hopkins clinicians and researchers, training related to unit teamwork and safety culture was a key. Principles of CUSP (Comprehensive Unit-based Safety Program) are a core element (see our March 2011 What's New in the Patient Safety World column “Michigan ICU Collaborative Wins Big” for comments about CUSP and links to resources).
The training emphasized evidence-based practices:
The above collaborative was sponsored by AHRQ, NIH and several other organizations. Another collaborative of hospitals in the Hospital Innovation and Improvement Network (HIIN) project led by the Centers for Medicare & Medicaid Services (CMS) and the Partnership for Patients (PFP) used the HRET Preventing Ventilator-Associated Events Change Package (HRET 2017). That describes how the elements of the ABCDEF Bundle (see our September 20, 2016 Patient Safety Tip of the Week “”) can be implemented and reduce the rate of ventilator-associated events.
Collaboratives which promote adherence to evidence-based interventions have usually demonstrated successful outcomes. However, the core elements of CUSP and culture training are critical to the success of such collaboratives. We always tell hospitals that patient safety projects are much more likely to be successful when implemented at the unit level than across entire institutions.
