Anxiety and health-related quality of life of patients undergoing total hip arthroplasty for osteoarthritis.

OBJECTIVE: Osteoarthritis in a hip not only causes pain and decreases physical function, which are the most common reasons for total hip arthroplasty, but also causes anxiety and reduces patients' health-related quality of life (HRQoL). The objective of this study was to evaluate patients' anxiety and its possible relationship with HRQoL before and after surgery.
METHODS: In this longitudinal follow-up study, the State Trait Anxiety Inventory was used to measure patients' (n = 100) level of anxiety before surgery and at 1 month, 3 months and 6 months post-operatively. The Sickness Impact Profile was used to measure patients' total HRQoL before surgery and post-operatively at 3 and 6 months.
RESULTS: Before surgery, patients' trait and state anxiety were moderate. Patients' pre-operative trait anxiety impaired HRQoL both before and after surgery. After surgery, state anxiety remained at a moderate level, although a few minor peaks were observed, but no relationship between state anxiety and HRQoL was found. DISCUSSION: Patients' needs and characteristics should be carefully assessed when planning post-operative care and support. Nurses should be aware of factors that may relate to anxiety and also consider different methods of supporting patients' recovery.
