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.

Summary
This summary is machine-generated.

Racial disparities exist in total joint arthroplasty (TJA) outcomes. Asian, African American, and Hispanic patients showed lower functional scores and minimal clinically important differences (MCID) post-TJA compared to White patients.

Area of Science:

  • Orthopedics
  • Health Services Research
  • Health Equity

Background:

  • Racial and ethnic disparities in total joint arthroplasty (TJA) outcomes are not well understood.
  • Investigating these differences is crucial for improving patient care and outcomes.

Purpose of the Study:

  • To examine racial and ethnic variations in clinical and patient-reported functional outcomes following TJA.
  • To compare outcomes among Non-Hispanic White, African American, Hispanic, Asian, and Native American populations.

Main Methods:

  • Retrospective review of 896,154 total hip arthroplasties (THAs) and 1,401,359 total knee arthroplasties (TKAs) from 2012-2022.
  • Analysis of patient-reported outcome measures (PROMs) and demographic data.
  • Multivariate regression models to identify predictors of functional outcomes.

Main Results:

  • Asian patients had lower odds of achieving minimal clinically important difference (MCID) after TJA compared to White patients.
  • African American and Hispanic patients reported significantly lower postoperative functional scores after THA.
  • African American, Asian, and Hispanic patients reported significantly lower functional scores after TKA.

Conclusions:

  • Significant racial and ethnic differences in TJA outcomes are evident.
  • While all groups improved, certain minority populations face greater challenges in achieving optimal functional recovery.
  • Further research is needed to understand the underlying causes and develop targeted interventions.
