Abstract
There is an urgent need to understand, measure, and improve the delivery of health care in the United States. No such instrument currently exists to measure the change in work productivity following stressful events such as workplace violence (WPV) or trauma patient care. The origins, development process, and psychometric properties of the Healthcare Productivity Survey (HPS), a new instrument for measuring the change in work productivity related to the cognitive, workload, support, communication, safety, and competency demands of health care providers, are described. The instrument was tested with a sample of emergency nurses who had experienced WPV and/or provided care to traumatically injured patients. The 29-item HPS is a valid and reliable instrument for measuring changes in work productivity following events of WPV. The instrument should be used with caution following events of trauma patient care.
