Objective:
To collect and prioritize the frequently asked questions (FAQs) that patients with hip or knee osteoarthritis (OA) and health care professionals consider to be the most important; to identify informational needs that go beyond guideline recommendations.
Methods:
FAQs were collected among health care professionals and from the arthritis helpline of the Dutch Arthritis Foundation. After deleting overlapping FAQs, the remaining FAQs were prioritized by patients and health care professionals using a maximum difference scaling method. A hierarchical Bayesian method was used to calculate relative importance scores. Differences between health care professionals and patients were analyzed using independent t-tests.
Results:
A total of 28 health care professionals and the arthritis helpline provided 192 FAQs. After deleting overlapping FAQs, 60 FAQs were prioritized by 94 patients (57 [60.6%] women, mean age 67.3 years) and 122 health care professionals (67 [54.9%] women, mean age 45.7 years). The FAQ "What can I do myself to decrease symptoms and to prevent the OA from getting worse?" was prioritized as the most important by both patients and professionals. FAQs that were highly prioritized by patients but significantly different from professionals were more directed toward treatment options offered by health care professionals, whereas highly prioritized FAQs of professionals were more often focused on treatment options involving self-management.
Conclusion:
The health care professionals' perspective on informational needs differs from that of OA patients. These differences are important to address in order to achieve more active involvement of patients in their own treatment process.

Exercise Stress Test
Exercise stress testing, commonly known as a treadmill test, is a noninvasive procedure used to evaluate cardiovascular function and diagnose heart conditions.
Definition
An exercise stress test measures the heart's response to exertion using a treadmill or stationary bicycle. Chest electrodes record the heart's electrical activity through an ECG, and blood pressure is monitored regularly.
