OBJECTIVES: Using an electronic health record (EHR)-enabled pediatric lupus registry, we evaluated high-quality care delivery in the context of provider goal-setting activities and a multidisciplinary care model. 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 auto-populate a SLE registry. We compared pediatric lupus care index (p-LuCI) performance (range 0.0-1.0; 1.0 representing perfect metric adherence) and timely follow-up a) before vs. during provider goal-setting activities and population management, and b) in multidisciplinary lupus nephritis vs. rheumatology clinic. We estimated associations between p-LuCI 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/patient [IQR 4-10]) over 3.5 years. The provider-directed activity was associated with improved p-LuCI performance (adjusted β 0.05, 95%CI [0.01-0.09]; mean 0.74 vs. 0.69). Patients with nephritis in multidisciplinary clinic had higher p-LuCI (adjusted β 0.06, 95%CI [0.02-0.10]) and likelihood of timely follow-up than those in rheumatology (adjusted RR 1.27, 95%CI [1.02-1.57]). p-LuCI ≥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 associates with better outcomes in childhood SLE. Multidisciplinary care models with population management may additionally facilitate equitable care delivery. This article is protected by copyright. All rights reserved.

<p><strong>PURPOSE: </strong>To examine the validity of International Classification of Diseases, 10th Revision, (ICD-10) code-based algorithms for herpes zoster (HZ) in the electronic medical record (EMR) of a large, integrated pediatric healthcare network and to examine baseline demographics and chronic comorbidities associated with HZ in a representative pediatric population.</p>

<p><strong>METHODS: </strong>We reviewed the electronic charts of all patients with a single ICD-10 for HZ (B02.xx) as their primary or secondary diagnosis in the EMR of the Children's Hospital of Philadelphia (CHOP) healthcare network from January 2010 - March 2019. The positive predictive value (PPV) for a single code for HZ was calculated and alternative algorithms were examined to determine which method resulted in the highest PPV.</p>

<p><strong>RESULTS: </strong>The PPV for a single ICD-10 code was 91.7% (95% CI 80.8-95.4) for definitive and/or probable cases of HZ and 63.9% (95% CI 53.4-75.5%) for definitive cases alone. Adding a prescription for an antiviral did not improve the PPV. However, adding a new code for rash entered within 1 week of the HZ code increased the PPV to 100% for definitive and/or probable cases but with substantial loss of sensitivity. A high proportion of children with HZ who required inpatient hospitalization had chronic disease (70%) and were on systemic immunomodulatory therapy (50%).</p>

<p><strong>CONCLUSIONS: </strong>HZ can be identified with a high PPV in electronic medical records of children using ICD-10 code alone. These findings lay the foundation for future pharmacoepidemiologic research to better understand risk factors for HZ infection.</p>
