Pilot RCT Comparing Effectiveness of Two Decision Aids for Hip and Knee Osteoarthritis

Massachusetts General Hospital58 enrolled

Overview

This pilot RCT study is to examine the comparative effectiveness of two decision aids for hip and knee osteoarthritis.

This pilot RCT study is to examine the comparative effectiveness of two decision aids for hip and knee osteoarthritis. The vendors employ different design features (e.g. use of video for patient narratives, interactive values clarification exercise) and the study will examine the relative impact of the different features on decision quality. Eligible subjects will be randomly assigned to receive one of two decision aids before their upcoming clinic visit with a participating provider. Immediately before the visit, participants will complete a short questionnaire about the decision aid. This pilot study will assist with determining the potential difference between these two decision aids on improving knowledge and use of decision aids.

Outcomes

Primary Outcomes

Hip and Knee Decision Quality Instruments Knowledge Subscale Scores

5 multiple choice knowledge items from the Hip and Knee Decision Quality Instruments will be averaged into a knowledge subscale score (0-100%) with higher scores indicating higher knowledge.

Time frame: In clinic, immediately before the first visit with surgeon

Secondary Outcomes

Percentage of Participants Who Used the Decision Aid

1 item asking patients how much they reviewed the program (none, some. most, all). The percentage who report viewing most or all will be calculated.

Time frame: In clinic, immediately before the first visit with surgeon

Percentage of Participants With a Clear Treatment Preference

1 item assessing patient's treatment preference (surgery, non-surgical options, or not sure). The percentage who have a clear preference (either for surgery or non surgical options) will be calculated.

Time frame: In clinic, immediately before the first visit with surgeon
