Burden of Herpes Zoster Among Patients with Psoriasis in the United States.

INTRODUCTION: Patients with psoriasis (PsO) are at increased risk of herpes zoster (HZ), but recent data on the incidence of HZ among patients with PsO and the impact of HZ on healthcare resource use (HRU) and costs for patients with PsO have not been described. METHODS: This retrospective, longitudinal, cohort study estimated HZ incidence in cohorts of adults with vs without PsO (PsO + vs PsO-) and HRU and costs among those with PsO, with vs without HZ (PsO + /HZ + vs PsO + /HZ-) using Optum's de-identified Clinformatics Data Mart Database during 2015-2020. Patients with psoriatic arthritis were excluded from all four cohorts. Comparisons between cohorts used generalized linear models to adjust outcomes based on various baseline characteristics. RESULTS: The incidence rate of HZ was significantly higher in the PsO + (n = 144,115) vs PsO- (n = 23,837,237) cohorts at 11.35 vs 7.67 per 1000 patient-years; adjusted incidence rate ratio (aIRR): 1.21, 95% confidence interval (CI): 1.16-1.25. HRU (outpatient, emergency department, and inpatient) was significantly higher in the PsO + /HZ + (n = 1859) vs PsO + /HZ- (n = 78,664) cohorts during 1 month and 3 months after HZ diagnosis (e.g., outpatient visits during month: 2.83 vs 1.30 per patient; aIRR: 1.96; 95% CI 1.86-2.06). Mean all-cause costs were also significantly higher in the PsO + /HZ + vs PsO + /HZ- cohort during both month ($5020 vs $2715 per patient; adjusted cost difference: $1390; 95% CI $842-$1964) and 3 months ($12,305 vs $8256; adjusted cost difference: $1422; 95% CI $280-$2889) after HZ diagnosis. CONCLUSION: These findings show the increased incidence of HZ among patients with PsO and the clinical and economic burdens of HZ in this population. Considering the high prevalence of PsO, insights into the impact of HZ in these patients provide valuable evidence to inform clinical decision-making.

Psoriasis is an inflammatory condition that causes flaky, scaly skin. Herpes zoster (shingles) causes a painful rash, usually on the abdomen. However, recent data on the proportion of patients with psoriasis who develop herpes zoster is lacking. Furthermore, little is known about the healthcare resources that are used or the costs of care for patients with psoriasis who develop herpes zoster. We found that patients with psoriasis were 21% more likely to have herpes zoster than patients without psoriasis. Among patients with psoriasis, those who developed herpes zoster had twice as many doctor's visits, 3 times as many emergency department visits, and twice as many inpatient hospital stays during the month after a herpes zoster diagnosis as patients without herpes zoster. This resulted in an additional cost of $1390 per patient with psoriasis and herpes zoster compared with those with psoriasis but without herpes zoster. Overall, patients with psoriasis are at increased risk of developing herpes zoster and the healthcare resource use and associated cost of treating herpes zoster in patients with psoriasis is substantial.

Corticosteroid Use and Adherence in Patients Treated with Acthar Gel for Advanced Sarcoidosis.

INTRODUCTION: Long-term corticosteroid use in immune-mediated diseases is associated with increased risk of adverse events (AEs) and worsened health-related quality of life (HRQoL). Previous studies report chronic high-dose corticosteroid therapy results in higher rates of healthcare resource use and AE-related medical costs. Recent studies suggest Acthar® Gel (repository corticotropin injection) is an effective steroid-sparing therapy for sarcoidosis. This study compares the corticosteroid-sparing effect between Acthar Gel and comparators and evaluates the impact of Acthar Gel adherence on reduction of corticosteroid burden. METHODS: A retrospective analysis of a large administrative pharmacy and medical claims database (Symphony Health Solutions) was conducted. Patients were included with confirmed ICD-9/10 diagnosis for sarcoidosis in the study period (2014-2020), followed by ≥ 2 Acthar Gel claims or comparators (janus kinase inhibitor (JAKi)/rituximab), ≥ 18 years old, with 12 months coverage pre/post index. Outcomes were compared as change from baseline. Acthar Gel adherence was determined by proportion of days covered in the follow-up period. RESULTS: The Acthar Gel (n = 735) and comparator (n = 626) cohorts were mostly female (68-72%) between 55 and 58 years old. Compared to the comparator cohort at baseline, Acthar Gel patients had greater any corticosteroid use (80% vs. 56%, p < 0.001), extended use (61% vs. 32%, p < 0.001), and mean average daily dose (6.72 vs. 3.03, p < 0.001). After treatment, Acthar Gel patients had greater reduction from baseline in any corticosteroid use (- 9.0% vs. - 3.2%) and extended use (- 10.0% vs. - 3.0%). In the Acthar Gel adherence cohorts, patients with above average adherence had greater reduction in both measures (- 11.2% vs. - 6.1%; - 11.6% vs. - 7.6%, respectively) than patients with below average adherence. Acthar Gel patients had greater reduction of extended use at all dose levels. CONCLUSION: Acthar Gel is associated with reductions in corticosteroid use compared to alternatives. Better adherence is associated with greater reduction in corticosteroid exposure. Key Summary Points.

Patients who use corticosteroids long term for advanced sarcoidosis often suffer from negative health effects. This project aimed to evaluate whether Acthar^® Gel (repository corticotropin injection) use led to reduced corticosteroid use and whether higher adherence to Acthar Gel led to further reduction in corticosteroid use. Pharmacy and medical claims data were used to identify patients who fit certain criteria: the Acthar Gel cohort included patients with sarcoidosis who used Acthar Gel and the comparator cohort included patients with sarcoidosis who used janus kinase (JAK) inhibitors or rituximab. The Acthar Gel cohort was split into high adherence and low adherence. The Acthar Gel cohort was found to have higher corticosteroid use than the comparator group in the baseline period before initiating Acthar Gel or a comparator therapy. After initiating treatment, Acthar Gel patients had a larger reduction in corticosteroid use according to a variety of metrics including number of corticosteroid fills and extended use fills. Furthermore, when comparing those with high Acthar Gel adherence and those with low Acthar Gel adherence, the patients with above average adherence had a larger reduction in the number of corticosteroid fills and extended use fills than patients with below average adherence to Acthar Gel. Patients who use Acthar Gel and more regularly tended to use corticosteroids less, which may allow them to avoid the negative health effects from long-term, high-dosage corticosteroid use. This finding may help providers and health plans evaluate situations in which Acthar Gel treatment may be beneficial to improve patient outcomes.

Burden of hyperphagia and obesity in Bardet-Biedl syndrome: a multicountry survey.

BACKGROUND: Signs and symptoms of Bardet-Biedl syndrome (BBS) occur during early childhood, progress over time, and place substantial, multifaceted burden on patients and their caregivers. Hyperphagia may be a contributing factor to early-onset obesity in BBS; however, there are limited insights into its impacts on patients and caregivers. We quantified disease burden as it relates to the physical and emotional impacts of hyperphagia in BBS. METHODS: The CAREgiver Burden in BBS (CARE-BBS) study was a multicountry, cross-sectional survey of adult caregivers of patients with BBS who have had hyperphagia and obesity. The survey consisted of questionnaires including Symptoms of Hyperphagia, Impacts of Hyperphagia, Impact of Weight on Quality of Life (IWQOL)-Kids Parent Proxy, and Patient-Reported Outcome Measurement Information System (PROMIS) v1.0-Global Health 7. In addition, clinical characteristics, medical history, and weight management questions were included. Outcomes were scored and summarized descriptively in aggregate and by country, age, and obesity severity according to weight class. RESULTS: There were 242 caregivers of patients with BBS who completed the survey. Caregivers observed hyperphagic behaviors throughout the day, with negotiating for food (90%) and waking up and asking or looking for food during the night (88%) being the most frequent. Hyperphagia had at least a moderate negative impact on most patients' mood/emotions (56%), sleep (54%), school (57%), leisure (62%), and familial relationships (51%). Hyperphagia affected concentration at school (78%), and symptoms of BBS contributed to patients missing ≥ 1 day of school a week (82%). Responses from the IWQOL-Kids Parent Proxy suggested obesity most greatly negatively affected physical comfort (mean [standard deviation (SD)], 41.7 [17.2]), body esteem (41.0 [17.8]), and social life (41.7 [18.0]). On the PROMIS questionnaire, mean (SD) global health score for pediatric patients with BBS and overweight or obesity (36.8 [10.6]) was lower than the general population (mean, 50). CONCLUSIONS: Evidence from this study suggests that hyperphagia and obesity may have broad negative impacts on the lives of patients with BBS, including physical health, emotional well-being, school performance, and personal relationships. Therapies that target hyperphagia may alleviate the extensive clinical and nonclinical impacts experienced by patients with BBS and their caregivers.

Caregiver burden in Bardet-Biedl syndrome: findings from the CARE-BBS study.

BACKGROUND: Bardet-Biedl syndrome (BBS) is a rare, genetically heterogeneous obesity syndrome associated with hyperphagia. Given the early onset of BBS symptoms in childhood and multifaceted complications, this study aimed to quantify the caregiver burden associated with BBS. METHODS: A cross-sectional, multi-country survey of caregivers from the United States (US), United Kingdom (UK), Canada, and Germany was designed to quantify the extent of caregiver burden associated with obesity and hyperphagia symptoms (i.e., uncontrollable hunger) among patients with BBS. RESULTS: A total of 242 caregivers across the four countries met the inclusion criteria and completed the survey. The mean (standard deviation [SD]) age of the caregivers was 41.9 (6.7) years, and the mean (SD) age of individuals with BBS in their care was 12.0 (3.7) years. Hyperphagia contributed to a BBS diagnosis in 230 of 242 individuals (95.0%). On average, caregivers used eight different weight management approaches for those in their care and expressed a strong desire for more effective weight management methods. Based on the Impacts of Hyperphagia: Caregiver version, patients' hyperphagia had a moderate-to-severe impact on caregiver mood (56.6%), sleep (46.6%), and relationships (48.0%). Caregivers reported experiencing a high level of personal strain (mean [SD], 17.1 [2.9]) and family impact (mean [SD] score, 26.0 [3.8]) due to BBS, as measured by the Revised Impact on Family Scale. Among caregivers in the workforce, there also was high impairment in total work productivity (mean [SD], 60.9% [21.4%]) due to caring for patients with BBS according to the Work Productivity and Activity Impairment. More than half (53%) of the caregivers reported spending over 5,000 out-of-pocket in local currency for medical expenses for the patient with BBS in their care. CONCLUSIONS: Obesity and hyperphagia have negative impacts on the lives of caregivers of patients with BBS. The burden is demonstrated to be multifaceted, with various components that may interact with and confound each other, including intensive weight management efforts, productivity loses, impaired family dynamics and out-of-pocket medical expenses.

Development of a specialty intensity score to estimate a patient's need for care coordination across physician specialties.

BACKGROUNDS AND AIMS: This article develops a Specialty Intensity Score, which uses patient diagnosis codes to estimate the number of specialist physicians a patient will need to access. Conceptually, the score can serve as a proxy for a patient's need for care coordination across doctors. Such a measure may be valuable to researchers studying care coordination practices for complex patients. In contrast with previous comorbidity scores, which focus primarily on mortality and utilization, this comorbidity score approximates the complexity of a patient's the interaction with the health care system. METHODS: We use 2015 inpatient claims data from the Centers for Medicare and Medicaid Services to model the relationship between a patient's diagnoses and physician specialty usage. We estimate usage of specialist doctors by using a least absolute shrinkage and selection operator Poisson model. The Specialty Intensity Score is then constructed using this predicted specialty usage. To validate our score, we test its power to predict the occurrence of patient safety incidents and compare that with the predictive power of the Charlson comorbidity index. RESULTS: Our model uses 127 of the 279 International Classification of Disease, 10th Revision, Clinical Modification (ICD-10-CM) diagnosis subchapters to predict specialty usage, thus creating the Specialty Intensity Score. This score has significantly greater power in predicting patient safety complications than the widely used Charlson comorbidity index. CONCLUSION: The Specialty Intensity Score developed in this article can be used by health services researchers and administrators to approximate a patient's need for care coordination across multiple specialist doctors. It, therefore, can help with evaluation of care coordination practices by allowing researchers to restrict their analysis of outcomes to the patients most impacted by those practices.
