Racial and Ethnic Differences in Total Knee Arthroplasty in the Veterans Affairs Health Care System, 2001-2013.

ABSTRACT:

Objective

To examine black-white and Hispanic-white differences in total knee arthroplasty from 2001 to 2013 in a large cohort of patients diagnosed with osteoarthritis (OA) in the Veterans Affairs (VA) health care system.

Methods

Data were from the VA Musculoskeletal Disorders cohort, which includes data from electronic health records of more than 5.4 million veterans with musculoskeletal disorders diagnoses. We included white (non-Hispanic), black (non-Hispanic), and Hispanic (any race) veterans, age ?50 years, with an OA diagnosis from 2001-2011 (n?=?539,841). Veterans were followed from their first OA diagnosis until September 30, 2013. As a proxy for increased clinical severity, analyses were also conducted for a subsample restricted to those who saw an orthopedic or rheumatology specialist (n?=?148,844). We used Cox proportional hazards regression to examine racial and ethnic differences in total knee arthroplasty by year of OA diagnosis, adjusting for age, sex, body mass index, physical and mental diagnoses, and pain intensity scores.

Results

We identified 12,087 total knee arthroplasty procedures in a sample of 473,170 white, 50,172 black, and 16,499 Hispanic veterans. In adjusted models examining black-white and Hispanic-white differences by year of OA diagnosis, total knee arthroplasty rates were lower for black than for white veterans diagnosed in all but 2 years. There were no Hispanic-white differences regardless of when diagnosis occurred. These patterns held in the specialty clinic subsample.

Conclusion

Black-white differences in total knee arthroplasty appear to be persistent in the VA, even after controlling for potential clinical confounders.

Project description:ImportanceAlthough racial/ethnic differences in functional outcomes after total knee arthroplasty (TKA) exist, whether such differences are associated with differences in presurgical physical function (PF) has not been thoroughly investigated.ObjectiveTo examine trajectories of PF by race/ethnicity before and after TKA among older women.Design, setting, and participantsThis cohort study was conducted among the prospective Women's Health Initiative with linked Medicare claims data. A total of 10 325 community-dwelling women throughout the United States with Medicare fee-for-service underwent primary TKA between October 1, 1993, and December 31, 2014, and were followed up through March 31, 2017.ExposuresRace/ethnicity comparisons between Hispanic or Latina women, non-Hispanic black or African American women, and non-Hispanic white women (hereafter referred to as Hispanic, black, and white women, respectively).Main outcomes and measuresPhysical functioning scale scores and self-reported activity limitations with walking 1 block, walking several blocks, and climbing 1 flight of stairs were measured by the RAND 36-Item Health Survey during the decade before and after TKA, with a median of 9 PF measurements collected per participant over time.ResultsIn total, 9528 white women (mean [SD] age at surgery, 74.6 [5.5] years), 622 black women (mean [SD] age at surgery, 73.1 [5.3] years), and 175 Hispanic women (mean [SD] age at surgery, 73.1 [5.2] years) underwent TKA. During the decade prior to TKA, black women had lower PF scores than white women (mean difference, -5.8 [95% CI, -8.0 to -3.6]) and higher odds of experiencing difficulty walking a single block (5 years before TKA: odds ratio, 1.86 [95% CI, 1.57-2.21]), walking multiple blocks (odds ratio, 2.14 [95% CI, 1.83-2.50]), and climbing 1 flight of stairs (odds ratio, 1.81 [95% CI, 1.55-2.12]). After TKA, black women continued to have lower PF scores throughout the decade (mean difference 1 year after TKA, -7.8 [95% CI, -10.8 to -4.9]). After adjusting for preoperative PF scores, PF scores after TKA were attenuated (mean difference 1 year after TKA, -3.0 [95% CI, -5.3 to -0.7]), with no statistically significant differences in long-term follow-up. Hispanic women had similar PF scores to white women during the pre-TKA and post-TKA periods.Conclusions and relevanceThis study suggests that black women had significantly poorer PF than white women during the decades before and after TKA. Poorer PF after surgery was associated with poorer preoperative PF. Reducing disparities in post-TKA functional outcomes should target maintenance of function preoperatively in the early stages of arthritic disease and/or reduction of delays to receiving TKA once need arises.

Project description:BackgroundSignificant racial/ethnic disparities in unintended pregnancy persist in the United States, with the highest rates observed among low-income black and Hispanic women. Differences in contraceptive preferences, beliefs, and self-efficacy may be instrumental in understanding contraceptive behaviors that underlie higher rates of unintended pregnancy among racial/ethnic minorities.ObjectivesOur objective was to understand how contraceptive preferences, beliefs, and self-efficacy vary by race and ethnicity among women veterans.Study designWe analyzed data from the Examining Contraceptive Use and Unmet Need Study, a national telephone survey of women veterans aged 18-44 years who had received primary care at the Veterans Administration in the prior 12 months. Participants rated the importance of various contraceptive characteristics and described their level of agreement with contraceptive beliefs using Likert scales. Contraceptive self-efficacy was assessed by asking participants to rate their certainty that they could use contraception consistently and as indicated over time using a Likert scale. Multivariable logistic regression was used to examine associations between race/ethnicity and contraceptive attitudes, controlling for age, marital status, education, income, religion, parity, deployment history, and history of medical and mental health conditions.ResultsAmong the 2302 women veterans who completed a survey, 52% were non-Hispanic white, 29% were non-Hispanic black, and 12% were Hispanic. In adjusted analyses, compared with whites, blacks had lower odds of considering contraceptive effectiveness extremely important (adjusted odds ratio; 0.55, 95% confidence interval, 0.40-0.74) and higher odds of considering the categories of does not contain any hormones and prevents sexually transmitted infections extremely important (adjusted odds ratio, 1.94, 95% confidence interval, 1.56-2.41, and adjusted odds ratio; 1.99, 95% confidence interval, 1.57-2.51, respectively). Hispanics also had higher odds than whites of considering the category of does not contain any hormones and prevents sexually transmitted infections extremely important (adjusted odds ratio, 1.72, 95% confidence interval, 1.29-2.28, and adjusted odds ratio, 1.63; 95% confidence interval, 1.21-2.19, respectively). Compared with whites, blacks and Hispanics had higher odds of expressing fatalistic beliefs about pregnancy (adjusted odds ratio, 1.79, 95% confidence interval, 1.35-2.39, and adjusted odds ratio, 1.48, 95% confidence interval, 1.01-2.17, respectively); higher odds of viewing contraception as primarily a woman's responsibility (adjusted odds ratio, 1.92, 95% confidence interval, 1.45-2.55, and adjusted odds ratio, 1.77; 95% confidence interval, 1.23-2.54, respectively); and lower odds of being very sure that they could use a contraceptive method as indicated over the course of a year (adjusted odds ratio, 0.73, 95% confidence interval, 0.54-0.98, and adjusted odds ratio, 0.66, 95% confidence interval, 0.46-0.96, respectively).ConclusionWomen veterans' contraceptive preferences, beliefs, and self-efficacy varied by race/ethnicity, which may help explain observed racial/ethnic disparities in contraceptive use and unintended pregnancy. These differences underscore the need to elicit women's individual values and preferences when providing patient-centered contraceptive counseling.
