Osteoarthritis of the knee is a chronic disease associated with pain and reduced quality of life. The ability to reliably measure patient-reported symptoms is important for clinical decision making and evaluation of outcomes. Electronic and web-based tools can eliminate much of the labor-intensive aspects of questionnaire administration and enables both real-time evaluation of responses by physicians and integration of data from multiple sites. This article describes the results of implementing a single integrated electronic questionnaire system into routine orthopedic practice at 2 diverse institutions.
Case study.
A web-based version of a general quality-of-life questionnaire (EuroQol 5-dimension [EQ-5D]) and the pain domain of a disease-specific questionnaire (Knee Osteoarthritis Outcome Score [KOOS]) were administered in the office waiting room to (n = 666) patients at 2 centers over a 9-month period using touchscreen devices. Data were analyzed and descriptive statistics were calculated to assess feasibility of integration into the distinct work flows and to assess the agreement of the results.
The electronic questionnaire had a completion rate of 93% to 95%. Average questionnaire completion times were 3 to 5 minutes at each institution. Mean EQ-5D and KOOS scores for patients pre- and postsurgery were also consistent with prior literature studies.
Lessons learned for future adoption of questionnaire systems elsewhere include the need for baseline assessment of clinic work flows to identify the optimal point of administration and the need for IT support. This study demonstrates the feasibility of routinely collecting patient-reported data as part of standard care, which will become increasingly important as the nationwide emphasis on tracking quality and cost-effectiveness of treatments in orthopedics grows.
