Impact of telemedicine on disease activity assessment: A case-crossover study nested within a cohort of patients with systemic lupus erythematosus.

INTRODUCTION: The utilisation of telemedicine has been rapidly growing among patients with rheumatic diseases, especially following the corona virus disease 2019 pandemic. Ease and convenience appear to dominate the reasons for this growth. However, the effects of this approach in patients with systemic lupus erythematosus (SLE) are yet to be revealed. In this study, we examined the effect of telemedicine on disease activity assessment and damage scores in patients with SLE. METHODS: This case-crossover study was nested within a national prospective cohort of patients with SLE in Saudi Arabia. Patients with SLE were included if they fulfilled the Systemic Lupus International Collaborating Clinics classification criteria between March 2020 and March 2021 and were assessed at three time points with 3 months between assessments, according to the standardised protocol of this cohort. Telemedicine was conducted for the first evaluation, while in-person assessments were used at the second and third visits. The primary outcome was the difference in the SLE disease activity index 2000 (SLEDAI-2K) score. The primary analysis was conducted using the repeated measure model and adjusted for potential confounders, including demographics, medications, and changes in steroid doses. Several sensitivity analyses were conducted to mitigate selection and time-varying confounders. RESULTS: A total of 92 participants were included in this study. Most patients were females (88%), with a mean (±standard deviation [SD]) age of 36 (±13) years. The mean (±SD) disease activity scores at baseline were as follows: SLEDAI-2K, 5 (±5); SLE responder index, 3.8 (±3.5); Systemic Lupus International Collaborating Clinics/American College of Rheumatology damage index, 1 (±1). The mean difference in SLEDAI-2K score was -1.641 (95% confidence interval -2.773 to -0.510, p = 0.005*) between telemedicine and follow-up visits. The results were consistent in all sensitivity analyses. CONCLUSION: We found that telemedicine assessment was associated with a much higher disease activity score than subsequent assessments, which may suggest an overestimation of disease activity and later assessment accuracy. Cautious adoption has been suggested for SLE patients with active disease.

An Examination of Infection Incidence and Management in Systemic Lupus Erythematosus Patients: A Five-Year Review from a Saudi Arabian Center.

BACKGROUND Systemic lupus erythematosus (SLE) is a chronic autoimmune condition often associated with an increased susceptibility to infections. The infections in patients with SLE, primarily involving the skin, respiratory tract, and urinary tract, can significantly complicate disease management. This study aimed to evaluate the occurrence, management, and patient outcomes associated with infections in a group of 74 SLE patients at a single center in Saudi Arabia, spanning a 5-year period. MATERIAL AND METHODS An observational, retrospective study was conducted at the King Khalid University Hospital, Riyadh, Saudi Arabia. Patient medical records from January 2016 to December 2020 were examined. All adult SLE patients (age >14 years, as per hospital policy), confirmed by SLICC criteria, and admitted due to infections (determined by quick Sequential Organ Failure Assessment or qSOFA scores) were included in the study. RESULTS Of the 74 SLE patients studied, 79.7% were administered hydroxychloroquine. A majority (83.8%) were classified as low-risk for sepsis-associated mortality based on qSOFA scores (0-1), a fact noted by 41.9% of rheumatology fellows. The sputum cultures most frequently identified were Klebsiella pneumoniae, yeast, and Haemophilus influenzae (each accounting for 33.3% of cases). Furthermore, 4.1% of patients had extended-spectrum beta-lactamases infections, and 2.7% tested positive for COVID-19. A history of sepsis was more commonly observed among non-survivors (P=0.010). CONCLUSIONS The majority of patients were classified as low-risk for sepsis-associated mortality based on qSOFA scores, with two-thirds prescribed antibiotics within 1 h. The primary causes of death were multiorgan failure and cardiac arrest.

Cost Consequence Analysis of Belimumab versus Standard of Care for the Management of Systemic Lupus Erythematosus in Saudi Arabia: A Retrospective Cohort Study.

BACKGROUND: Belimumab use for the management of systemic lupus erythematosus (SLE) has been limited, in part due to its high acquisition cost relative to the standard of care (SoC) and the uncertainties about its cost-effectiveness. Therefore, the aim of this study was to compare the cost and effectiveness of belimumab versus the SoC alone for the management of SLE using real-world data from the perspective of public healthcare payers in Saudi Arabia. METHODS: Data were retrieved from a national prospective cohort of SLE, Saudi Arabia. Adult SLE patients (≥18 yrs.) treated with belimumab plus the SoC or the SoC alone for at least six months were recruited. The effectiveness was measured using the Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2K). Unit costs for health services and prescription drugs were retrieved from the Saudi ministry of health. Nonparametric bootstrapping with inverse probability weighting was conducted to generate the 95% confidence limits for the cost and effectiveness. RESULTS: A total of 15 patients on belimumab plus the SoC and 41 patients on the SoC alone met the inclusion criteria and were included in the analysis. The majority of patients were females (91.07%) with a mean age of 38 years. The mean difference in cost and SLEDAI-2K score reduction between belimumab versus the SoC were USD 5303.16 [95% CI: USD 2735.61-USD 7802.52] and 3.378 [95% CI: 1.769-6.831], respectively. Belimumab demonstrated better effectiveness but higher cost in 96% of the bootstrap cost-effectiveness distributions. CONCLUSION: Future studies should use more robust research designs and a larger sample size to confirm the findings of this study.

Impact of COVID-19 outbreak on rheumatic patients' perceptions and behaviors: A cross-sectional study.

AIM: The dynamics of coronavirus disease 2019 (COVID-19) pandemic has become of special concern to the rheumatology community. Rheumatic patients are required to engage in effective health management but their behavior is often influenced by intrinsic and extrinsic factors. This cross-sectional study aims to examine patients' experiences during the current pandemic and its implication on their health perception and behavior. METHOD: A patient-centered electronic survey was used, randomly sampling rheumatic patients in Saudi Arabia during March and April 2020. Questions included patients' socio-demographics, diseases, medications, COVID-19 knowledge, source of information, fear level, disease activity perception, health care utilization, medication accessibility, and therapeutic compliance (measured using a modified version of Medication Adherence Reporting Scale). Correlation and regression coefficients were used to evaluate associations among the aforementioned variables. RESULTS: A total of 637 respondents were included. The majority were rheumatoid arthritis patients (42.7%). Patients' knowledge about COVID-19 was correlated with social media use (P = .012). Fear of COVID-19 infection correlated with healthcare facility for follow-up visits (P = .024) and fear of disease deterioration if contracting the infection correlated with patients' levels of knowledge (P = .035). Both types of fear did not correlate with patients' perceptions of disease activity. However, patients' perceptions of worsened disease activity were correlated with unplanned healthcare visits (P < .001), medication non-adherence, and difficulty accessing medication (P = .010 and .006, respectively). CONCLUSION: The COVID-19 pandemic and surrounding public health measures could affect rheumatic patients' health management which might contribute to disease flare-up and subsequently taxing healthcare systems even further.
