Quality of Care for the Screening, Diagnosis, and Management of Lupus Nephritis Across Multiple Health Care Settings

Improving Outcomes of Pediatric Lupus Care Delivery With Provider Goal-Setting Activities and Multidisciplinary Care Models

OBJECTIVE

The present study was undertaken to evaluate high-quality care delivery in the context of provider goal-setting activities and a multidisciplinary care model using an electronic health record (EHR)-enabled pediatric lupus registry. We then determined associations between care quality and prednisone use among youth with systemic lupus erythematosus (SLE).

METHODS

We implemented standardized EHR documentation tools to autopopulate a SLE registry. We compared pediatric Lupus Care Index (pLCI) performance (range 0.0-1.0; 1.0 representing perfect metric adherence) and timely follow-up 1) before versus during provider goal-setting activities and population management, and 2) in a multidisciplinary lupus nephritis versus rheumatology clinic. We estimated associations between pLCI and subsequent prednisone use adjusted for time, current medication, disease activity, clinical features, and social determinants of health.

RESULTS

We analyzed 830 visits by 110 patients (median 7 visits per patient [interquartile range 4-10]) over 3.5 years. The provider-directed activity was associated with improved pLCI performance (adjusted β 0.05 [95% confidence interval (95% CI) 0.01, 0.09]; mean 0.74 versus 0.69). Patients with nephritis in multidisciplinary clinic had higher pLCI scores (adjusted β 0.06 [95% CI 0.02, 0.10]) and likelihood of timely follow-up than those in rheumatology (adjusted relative risk [RR] 1.27 [95% CI 1.02, 1.57]). A pLCI score of ≥0.50 was associated with 0.72-fold lower adjusted risk of subsequent prednisone use (95% CI 0.53, 0.93). Minoritized race, public insurance, and living in areas with greater social vulnerability were not associated with reduced care quality or follow-up, but public insurance was associated with higher risk of prednisone use.

CONCLUSION

Greater attention to quality metrics is associated with better outcomes in childhood SLE. Multidisciplinary care models with population management may additionally facilitate equitable care delivery.

Does higher quality of care in systemic lupus erythematosus translate to better patient outcomes?

PURPOSE

To assess if high quality of care (QOC) in SLE results in improved outcomes of quality of life (QOL) and non-routine health care utilization (HCU).

METHODS

One hundred and forty consecutive SLE patients were recruited from the Rheumatology clinic at an academic center. Data on QOC and QOL were collected along with demographics, socio-economic, and disease characteristics at baseline. LupusPRO assessing health-related (HR) QOL and non (N)HRQOL was utilized. Follow up QOL and HCU were collected prospectively at 6 months. High QOC was defined as those meeting ≥80% of the eligible quality indicators. Univariate and multivariate regression analyses were performed with QOC and high QOC as independent variables and HRQOL and NHRQOL as dependent variables at baseline and follow up. Multivariable models were adjusted for demographics and disease characteristics. Secondary outcomes included non-routine HCU and disease activity at follow up.

RESULTS

Baseline and follow up data on 140 and 94 patients, respectively, were analyzed. Mean (SD) performance rate (QOC) was 78.6 (13.4) with 52% patients in the high QOC group. QOC was associated with better NHRQOL at baseline and follow up but not with HRQOL. Of all the NHRQOL domains, QOC was positively associated with treatment satisfaction. QOC or high QOC were not associated with non-routine HCU and were instead associated with higher disease activity at follow up.

CONCLUSION

Higher QOC predicted better NHRQOL by directly impacting treatment satisfaction in SLE patients in this cohort. Higher QOC, however, was not associated with HRQOL, HCU, or improvement in disease activity at follow up.

Association of clinic setting with quality indicator performance in systemic lupus erythematosus: a cross-sectional study

BACKGROUND

Healthcare quality for systemic lupus erythematosus (SLE) is a modifiable target for improving patient outcomes. We aimed to assess the quality of care processes in different clinic settings, comparing a subspecialty lupus clinic with hospital-based and private general rheumatology clinics.

METHODS

Patients with SLE (n = 258) were recruited in 2016 from a subspecialty lupus clinic (n = 147), two hospital general rheumatology clinics (n = 56) and two private rheumatology clinics (n = 55). Data were collected from medical records and patient questionnaires. Quality of care was assessed using 31 validated SLE quality indicators (QI) encompassing diagnostic work-up, disease and comorbidity assessments, drug monitoring, preventative care and reproductive health. Per-QI performance was measured as a percentage of patients that met the QI relative to the number of patients eligible. Per-patient QI performance was calculated as a percentage of QIs met relative to the number of eligible QIs for each patient. Per-QI and per-patient QI performance were compared between the three clinic settings, and multiple regression performed to adjust for sociodemographic, disease and healthcare factors.

RESULTS

Per-QI performance was generally high across all clinic settings for diagnostic work-up, comorbidity assessment, lupus nephritis, drug monitoring, prednisolone taper, osteoporosis and pregnancy care. Median [IQR] per-patient performance on eligible QIs was higher in the subspeciality lupus clinic (66.7% [57.1-74.1]) than the hospital general rheumatology (52.7% [47.5-58.1]) and private rheumatology (50.0% [42.9-60.9]) clinics (p <0.001) and the difference remained significant after multivariable adjustment. The subspecialty lupus clinic recorded higher per-QI performance for documentation of disease activity, disease damage, cardiovascular risk factor and drug toxicity assessments, pre-immunosuppression hepatitis and tuberculosis screening, new medication counselling, vaccinations, sun avoidance education and contraception counselling.

CONCLUSIONS

SLE patients managed in a subspecialty lupus clinic recorded higher per-patient QI performance compared to hospital general rheumatology and private rheumatology clinics, in part related to better documentation on certain QIs.

Multidisciplinary Lupus Nephritis Clinic Reduces Time to Renal Biopsy and Improves Care Quality

Objective

Patients with lupus nephritis (LN) have a 26‐fold higher mortality rate compared with their peers. Kidney biopsy, the gold standard diagnostic method for LN, may have an average wait time of more than 50 days. Other gaps in quality process measures during LN visits have also been reported. A subspecialty multidisciplinary clinic (MDC) can provide better care and quality in LN; therefore, we aimed to examine how an LN MDC impacted time to biopsy, time to treatment, and other quality measures.

Methods

We included all validated patients with LN who underwent diagnostic kidney biopsies between the 2011 to 2017 pre‐MDC period and the 2018 to 2020 post‐MDC period. We compared time to biopsy and treatment and quality measures between the two periods and examined factors associated with timely LN diagnosis, defined as a biopsy within 21 days.

Results

During the pre‐ and post‐MDC periods, 53 and 21 patients with LN underwent a diagnostic biopsy, respectively. We found a decrease in the median time to biopsy from 26 days to 16 days after starting the LN clinic (P = 0.014). Beyond clinical factors, the presence of social factors, such as being of a non‐White race and having food insecurity, were associated with 54% lower odds of timely diagnosis (adjusted Hazards Ratio [aHR] = 0.46; 95% confidence interval: 0.22‐0.93; P = 0.031). We found higher odds of quality measure performance during the post‐ versus pre‐MDC period.

Conclusion

Wait times to diagnose LN decreased by 40% and higher quality measure performance was noted after establishing an LN MDC. Systemic and social barriers predicted delays in diagnosis that may be addressed by MDCs.

Treatment of Childhood-onset Proliferative Lupus Nephritis in the 21st Century: A Call to Catch Up With the Evidence

Proliferative lupus nephritis (PLN) is associated with significant morbidity, mortality, and kidney failure, especially in childhood-onset PLN (cPLN). Therefore, it is important to treat it promptly and aggressively, while being cognizant of the risk-benefit ratio and side effects of therapies.

Use of Quality Measures to Identify Disparities in Health Care for Systemic Lupus Erythematosus

Assessment of quality of care for people with systemic lupus erythematosus (SLE) provides opportunities to identify gaps in health care and address disparities. Poor access to specialty care has been shown to negatively impact care in SLE and is associated with poor disease outcomes. Racial/ethnic minorities and those with low socioeconomic status are at higher risk for poor access and lower quality of care. Quality measures evaluating processes of care have shown significant deficiencies in care of SLE patients across studies. High SLE patient volume correlates with better quality of care for providers in hospital and ambulatory settings.
