Event type (ASC)
Description
Determination of the event type that is being reported.
Ambulatory surgery centers (ASCs) participating in PSRP are committed to reporting:
Any unanticipated, usually preventable event that results in patient harm.
Any serious adverse events—events that result in patient death or serious physical injury.
Any one of thirteen specific event types regardless of the severity of harm.
On-Screen Instructions
If the event consists of multiple event types, select only the precipitating event that best describes the situation. In rare cases, reports may involve two distinct adverse events in which case multiple adverse events may be selected.

Electric shock
Patient or staff death or serious injury associated with an electric shock in the course of a patient care process in a healthcare setting.
Includes

Fall
Patient death or serious injury associated with a fall while being cared for in a healthcare setting. "Fall" refers to unintentionally coming to rest on the ground, floor, or other lower level, but not as a result of an overwhelming external force (e.g., being pushed to the ground). An episode where a patient lost his/her balance and would have fallen, if not for staff intervention, is considered a fall. A fall without injury is still a fall. Unless there is evidence suggesting otherwise, when a patient is found on the floor, a fall is considered to have occurred.
Includes
Falls resulting in fractures, head injuries, intracranial hemorrhage
Patient falls or drops from equipment (e.g., bed, lift)
Patient would have fallen if they had not caught themselves or had not been assisted by another person
Excludes
An anticipated loss of balance resulting from a supervised therapeutic intervention, during which the patient’s balance is being intentionally challenged during balance training

History
Start Date | Spring 2012 |
---|---|
End Date | n/a |
Change History | May 2013: HIT removed as an event type. HIT was too hard to define as an event type, so it was moved into "Additional event questions" to be asked of all events. Additional specification added to Surgical or other invasive procedure and HAI. 2014: Prompt updated. January 2015: updated "Unintended retained foreign object" to "Unintended retained foreign object (includes retained surgical items)." |
