ObjectivesPatients with systemic lupus erythematosus (SLE) have a high risk of cardiovascular disease that could potentially increase postoperative major adverse cardiac events (MACE). We determined the rate of MACE in patients with SLE undergoing noncardiac surgery using national claims-based data.MethodsThis was a retrospective cohort study using Optum Clinformatics Data Mart from 2007 to 2020. We identified a cohort of patients with SLE who had undergone noncardiac surgeries using Current Procedural Terminology codes. We also identified two control cohorts without SLE, one with diabetes mellitus (DM) and one without DM. After matching cases and controls by age and sex, the odds of MACE were estimated using multivariable logistic regression models also including race and the Revised Cardiac Risk Index (RCRI) scores. We also examined use of preoperative cardiac testing.ResultsWe identified 4750 patients with SLE, 496,381 DM controls, and 1,484,986 non-DM controls. After matching, the odds ratio (OR) for MACE in patients with SLE versus non-DM controls was 1.51 (95% confidence interval 1.09-2.08), which decreased after adjustment for RCRI score (OR: 0.97, 95% confidence interval 0.7-1.36). No significant differences were observed in the incidence of MACE between patients with SLE and DM controls (0.82 vs 1.04, P=0.16). High-risk patients with SLE (RCRI score of ≥3) were less likely to receive preoperative cardiac testing than non-DM controls (42.7% vs 35.1%, P

Objective The objective of this study was to assess the efficacy of self-administered patient educational tools in improving knowledge and behaviors for the management of knee osteoarthritis. Methods We conducted a randomized clinical trial in patients with knee osteoarthritis to assess the efficacy of providing a video for entertainment education, in combination with two booklets, compared with providing the booklets alone. We evaluated changes in scores on a patient knowledge questionnaire, the Decisional Conflict Scale, the Arthritis Self-Efficacy Scale, and the Effective Consumer Scale between baseline and same day, 3 months, and 6 months post intervention. We used linear regression models to explore associations between demographic characteristics and outcomes, testing for interactions. Results Two hundred nineteen participants were randomly assigned to receive the video + booklets (n = 109) or the booklets alone (n = 110). The mean age of participants was 64.6 (±8.3) years. At 6 months, statistically significant improvements were observed in knowledge and decisional conflict scores for both groups, and statistically significant improvements in the behavior to participate in their health care were observed in the video + booklets group. The video + booklets group was more knowledgeable immediately post intervention than the booklet group (mean difference 0.39 [95% confidence interval 0.02-0.76]). No other significant changes in outcomes were observed at 6 months between the two groups. The video + booklets combination was associated with decreased decisional conflict in Spanish speakers and increased self-efficacy in those with less than a high school education. Conclusion Although both education strategies were associated with improved knowledge and reduced decisional conflict at 6 months, receiving the video + booklets in combination, compared with receiving the booklets alone, proved to be more effective in changing behaviors and appeared to have some advantages for Spanish speakers and those who were less educated.

Objective To evaluate the association of preoperative psychosocial and demographic factors with total knee arthroplasty (TKA) outcomes and satisfaction in patients with osteoarthritis (OA) of the knee at 24 months after surgery. Methods A prospective cohort study of patients undergoing TKA was conducted. Outcome measures included: Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and Short Form 36 (SF-36) scores at baseline and 24 months after surgery, and patient satisfaction with TKA at 24 months. Linear regression models were performed to evaluate the association of preoperative psychosocial determinants (ie, Medical Outcome Study Social Support Scale; Depression, Anxiety, and Stress Scale; Brief COPE inventory, The Life Orientation Test-Revised; Multidimensional Health Locus of Control; and Arthritis Self-Efficacy Scale) on outcomes. Results We included 178 patients. Increasing WOMAC pain scores at 24 months were associated with increasing age and body mass index (BMI); low tangible social support and low optimism were associated with higher levels of pain (R2 = 0.15). A decrease in WOMAC function scores was also associated with older age and higher BMI; low tangible support, increased stress, and low optimism were also associated with worse function (R2 = 0.22). When evaluating quality of life, lower SF-36 physical functioning scores at 24 months were associated with age, high BMI, and comorbidity (R2 = 0.34). Lower SF-36 mental functioning scores were associated with depression and low optimism (R2 = 0.38). Having a dysfunctional style of coping was associated with lower satisfaction with surgery after 24 months (adjusted R2 = 0.12). Conclusion Psychosocial factors, such as tangible support, depression, dysfunctional coping, and optimism, were associated with pain, function, and satisfaction 2 years after TKA. Perioperative programs identifying and addressing psychosocial problems may result in improvements in pain and function after TKA.

Objective To assess methotrexate (MTX) adherence using the Medication Event Monitoring System (MEMS) and characterize associations with adherence in patients with rheumatoid arthritis (RA). Methods Eligible patients participated in Forward, the National Databank for Rheumatic Diseases, and recently (12 months or sooner) initiated oral MTX. MEMS was used to compile MTX weekly dosing over 24 weeks. The Beliefs about Medicines Questionnaire (BMQ) was completed, and baseline demographics and disease characteristics obtained. MTX adherence (percentage of weeks dose taken correctly), implementation (percentage of weeks dose taken correctly from initiation until last dose), and persistence (duration from initiation to last dose) were calculated. Analyses measured associations between patient characteristics and adherence, modeled using logistic generalized estimating equations and censored Poisson regression, and persistence modeled using Cox regression. Results Overall, 60 of 119 eligible patients were included in the analysis. MTX adherence, implementation, and persistence were 75%, 80%, and 83%, respectively, at 24 weeks. Demographics and disease characteristics were generally similar between patients with 1 week or less and 2 weeks or more of missed MTX. Unemployment, less disability, higher Patient Global scores, and no prior disease-modifying antirheumatic drug (DMARD) use were associated with correct dosing. No significant differences in adherence were observed between patients receiving concomitant MTX versus MTX monotherapy, and biologic DMARD-experienced versus biologic DMARD-naive patients. Higher scores in BMQ Specific Necessity (indicating a greater belief in the necessity of the medication) was associated with a decreased likelihood of dosing at an interval shorter than prescribed (odds ratio 0.89). Conclusion Even in a participatory group over a short period, MTX adherence was suboptimal and associated with certain demographics, medication experience, and beliefs about medicines. This suggests a need for screening and alternative treatment opportunities in nonadherent MTX patients with RA.
