Increasing participation of registered nurses (RNs) in quality improvement (QI) is a promising strategy to close the health care quality chasm. For RNs to participate effectively in hospital QI, they must have adequate QI knowledge and skills. This descriptive study assessed employer-sponsored QI education and RNs' preparedness across a wide range of QI steps and processes. RNs from 15 U.S. states who were employed in hospitals and were initially licensed to practice in 2007 to 2008 were surveyed. Fewer than one third of respondents reported being very prepared across all measured QI topics. More than half reported receiving zero hours of training in these same topics in the last year. Lack of educational offerings on the topic was the top reason respondents gave for not obtaining QI training. The QI education offered by employers to RNs could be substantially improved. Nurse educators play a critical role in making these improvements.
