Risk assessment in adverse events
Abstract
The Veterans Administration has developed criteria that allow us to grade the severity of an adverse event and the likelihood of its recurrence.
Categories by probability:
1. Frequent: they occur repeatedly, they are repeated every short period.
2. Occasional: they occur several times every one or two years.
3. Infrequent: they can occur sometimes in two to five years.
4. Remote: they occur sometime in two to five years.
Categories by consequences:
1. Catastrophic: iatrogenic death or permanent loss of death due to the event analyzed.
2. Major: impaired function or physiognomy of a patient, need for surgical intervention or prolonged stay or greater level of care.
3. Moderate: increase in stay, higher expenses, greater need for monitoring.
4. Minor: no injury, no treatment required, loss of utility to the institution without harm to the patient.
