Summary

Ethnic differences influence treatment choices for knee osteoarthritis (OA). African Americans were less likely to opt for surgery compared to whites, suggesting preference disparities may contribute to varied knee replacement rates.

Surveys

Often, psychologists develop surveys as a means of gathering data. Surveys are lists of questions to be answered by research participants, and can be delivered as paper-and-pencil questionnaires, administered electronically, or conducted verbally. Generally, the survey itself can be completed in a short time, and the ease of administering a survey makes it easy to collect data from a large number of people.

Area of Science:

  • Orthopedics
  • Health Services Research
  • Medical Decision Making

Background:

  • Knee osteoarthritis (OA) affects millions, with treatment decisions often involving surgery or medical management.
  • Understanding patient preferences is crucial for equitable healthcare delivery and addressing disparities in treatment rates.

Purpose of the Study:

  • To investigate potential ethnic variations in patient preferences for surgical versus medical treatment of knee OA.
  • To explore demographic factors influencing treatment choice for knee OA.

Main Methods:

  • Employed conjoint analysis, a marketing technique, to assess preferences through hypothetical treatment scenarios.
  • Conducted cross-sectional interviews with 193 adults recruited via random digit dialing and 198 knee OA patients in Houston, TX.

Main Results:

  • African Americans showed a significantly lower likelihood of choosing surgery compared to White individuals (OR 0.63).
  • Women and older individuals were also less inclined towards surgery.
  • Greater expected symptom reduction strongly predicted a preference for surgical intervention.

Conclusions:

  • Differences in treatment preferences, particularly ethnic variations, may partially explain disparities in knee replacement rates.
  • Conjoint analysis proved to be a viable method for gathering patient preferences in health research.
  • This methodology offers valuable insights into factors driving healthcare decisions.
