UHN – TWH SPINAL PROCEDURES: ADVERSE EVENTS (AE)
Please read instructions carefully before completing. Adverse events are defined as any negative unexpected or undesirable event(s) that occur following a surgical procedure that is not due to the underlying disease process or injury.

Instructions:

1.) Adverse events are graded as follows:

IEvent requires minimal (e.g. simple UTI)or no treatment and has NO effect on outcome.

II Event requires medical or surgical treatment and has no permanent or prolonged negative effect on outcome.

III Event requires medical or surgical treatment and will have a permanent or prolonged negative effect on outcome.

IV Event Results in death.

2.) The effect of AE on LOS is graded as follows:

I Event increases LOS by 1-2 days

II Event increases LOS by 3-7 days.

III Event increases LOS by 7-14 days

IV Event increases LOS by > 14 days
