Positive effect of patient education for hip surgery: a randomized trial

The current trial compared patient education before total hip arthroplasty with the usual verbal information. A randomized, controlled 24-month prospective single-center study was done. Patients scheduled for a first elective total hip arthroplasty for primary hip osteoarthritis were enrolled. All patients were given the usual information and an information leaflet and completed a self-evaluation questionnaire (Spielberger State and Trait Anxiety Inventory). The patients were assigned randomly to two groups: Group 1 attended a collective multidisciplinary information session 2 to 6 weeks before surgery and the control group did not attend. All patients completed another State Anxiety Inventory just before surgery and then 1 and 7 days after surgery. One hundred patients were randomized. Forty-eight attended the collective information session. Patients receiving education were significantly less anxious just before surgery than patients in the control group, in linear regression after adjustment for gender, trait and state anxiety at baseline, depression score, and health assessment questionnaire score. They experienced less pain before surgery and were able to stand sooner. However, the trend toward lower anxiety scores was not statistically significant after surgery. Patient education decreases preoperative anxiety and pain in patients having hip surgery.
