Data Collection

All participating hospitals agreed to analysis and publication of aggregated data. Data from each hospital's PEVS system were uploaded to a secure database. Raw data (excluding protected health information as defined by the Health Insurance Portability and Accountability Act) from the hospitals' servers were securely exported monthly. The data were then aggregated to provide program metrics and national comparisons for database subscribers.

Measures chosen for analysis included:

verbal intervention: talk button used to speak directly to patient

PEVS alarm: alarm activated by monitoring staff in urgent or emergent situations

physical abuse event: aggressive behavior that may or may not result in injury to either the patient or the caregiver and reported by monitoring staff

   • combative event: behaviors such as flailing, swinging, and attempting to hit, not involving physical contact

   • physical contact: behaviors such as hitting, kicking, grabbing, slapping, and biting

verbal abuse event: abusive or demeaning language

abuse event avoided: event prevented via verbal intervention or PEVS alarm

The abuse events rate and the abuse events avoided rate were calculated by dividing the number of events by patient days on PEVS and multiplying by 1,000. This rate was chosen for consistency with national standards for reporting falls and falls-with-injury rates per 1,000 patient days.
