The provincial government ordered the review in May after Andre Noel Denny was charged with second-degree murder in Taavel's death.
Denny was granted a one-hour leave from the hospital on April 16 but he didn't return.
Hours later, Taavel's body was found outside a downtown bar.
The Health Department has said the review focused on patient supervision and public notification when a patient fails to return while out on a pass.
It also examined community access privileges granted to patients who have been found not criminally responsible.
Denny's case is due to return to Halifax provincial court Thursday.
