简介
Objectives
To determine chronic opioid use pre-THA (total hip arthroplasty) and post-THA, and risk factors for persistent or new chronic opioid use post-THA.
Design
Retrospective cohort study.
Setting
Australian Government Department of Veterans' Affairs health claims database.
Participants
9525 patients who had an elective unilateral THA between 1/01/2001 and 12/31/2012.
Primary outcome measure
Chronic opioid use. Defined as 90 days of continuous opioid use or 120 days of non-continuous use.
Results
Pre-THA, 6.2% (n=593) of patients were chronic users, while 5.2% (n=492) were post-THA. Among the 492 postoperative chronic users, 302 (61%) were chronic users pre-THA and post-THA and 190 (39%) became new chronic users after surgery. Risk factors for persistent chronic use were younger age (OR=0.96, 95% CI 0.93 to 0.99/1-year increment), back pain (OR=1.99, 95% CI 1.20 to 3.23), diabetes (OR …
