Work productivity burden and indirect costs associated with carcinoid syndrome diarrhea.

Objectives: We estimated the indirect costs of work productivity burden from carcinoid syndrome diarrhea (CSD) among employed, insured adults in the United States. Methods: Retrospective cohort study of patients ≥18 years old with CS who did and did not have CSD (2014-2016). Eligible patients had continuous health plan enrollment for ≥12 months prior to their first CS claim and for ≥30 days after. Univariate analyses of clinical and work productivity outcomes and indirect costs were conducted. Multivariate analyses examined associations of CSD with work productivity measures, controlling for baseline characteristics. Results: A total of 1,880 patients with CS were eligible, including 577 with CSD and 1,303 with CS only. Baseline characteristics were generally similar. Patients with CSD missed half of eligible workdays (median 56%, 146/260); those with CS-only missed one-third (38%, 100/260). Work productivity was lower and the associated costs were higher in the presence of CSD. Patients with CSD had more absenteeism, short-term disability, and lost workdays which translated into incremental mean costs of $16,679 greater than those with CS only. Conclusion: Indirect costs related to work productivity losses among adults with CSD are significant, which further add to the burden of CSD to society.

Direct costs of carcinoid syndrome diarrhea among adults in the United States.

BACKGROUND: The burden of carcinoid syndrome (CS) among patients with neuroendocrine tumors is substantial and has been shown to result in increased healthcare resource use and costs. The incremental burden of CS diarrhea (CSD) is less well understood, particularly among working age adults who make up a large proportion of the population of patients with CS. AIM: To estimate the direct medical costs of CSD to a self-insured employer in the United States. METHODS: CS patients with and without CSD were identified in the IBM® MarketScan® Database, including the Medicare Supplemental Coordination of Benefits database. Eligible patients had ≥ 1 medical claim for CS with continuous health plan enrollment for ≥ 12 mo prior to their first CS diagnosis and for ≥ 30 d after, no claims for acromegaly, and no clinical trial participation during the study period (2014-2016). Baseline demographic and clinical characteristics, including comorbidities and treatment, were analyzed using descriptive statistics. Measures of healthcare resource use and costs were compared between patients with and without CSD, including Emergency Department (ED) visits, hospital admissions and length of stay, physician office visits, outpatient services, and prescription claims, using univariate and multivariate analyses to evaluate associations of CSD with healthcare resource use and costs, controlling for baseline characteristics. RESULTS: Overall, 6855 patients with CS were identified of which 4,043 were eligible for the analysis (1352 with CSD, 2691 with CS only). Baseline demographic and clinical characteristics were similar between groups with the exception of age, underlying tumor type, and health insurance plan. Patients with CSD were older, had more comorbidities, and received more somatostatin analog therapy at baseline. Patients with CSD required greater use of healthcare resources and incurred higher costs than their peers without CSD, including hospitalizations (44% vs 25%) and ED visits (55% vs 31%). The total adjusted annual healthcare costs per patient were 50% higher (+ $23865) among those with CSD, driven by outpatient services (+ 56%), prescriptions (+ 48%), ED visits (+ 26%), physician office visits (+ 21%), and hospital admissions (+ 11%). CONCLUSION: The economic burden of CSD is greater than that of CS alone among insured working age adults in the United States, which may benefit from timely diagnosis and management.

Immunologic response among HIV-infected patients enrolled in a graduated cost-recovery programme of antiretroviral therapy delivery in Chennai, India.

BACKGROUND & OBJECTIVES: Sustainability of free antiretroviral therapy (ART) roll out programmes in resource-limited settings is challenging given the need for lifelong therapy and lack of effective vaccine. This study was undertaken to compare treatment outcomes among HIV-infected patients enrolled in a graduated cost-recovery programme of ART delivery in Chennai, India. METHODS: Financial status of patients accessing care at a tertiary care centre, YRGCARE, Chennai, was assessed using an economic survey; patients were distributed into tiers 1- 4 requiring them to pay 0, 50, 75 or 100 per cent of their medication costs, respectively. A total of 1754 participants (ART naοve = 244) were enrolled from February 2005-January 2008 with the following distribution: tier 1=371; tier 2=338; tier 3=693; tier 4=352. Linear regression models with generalized estimating equations were used to examine immunological response among patients across the four tiers. RESULTS: Median age was 34; 73 per cent were male, and the majority were on nevirapine-based regimens. Median follow up was 11.1 months. The mean increase in CD4 cell count within the 1 st three months of HAART was 50.3 cells/µl per month in tier 1. Compared to those in tier 1, persons in tiers 2, 3 and 4 had comparable increases (49.7, 57.0, and 50.9 cells/µl per month, respectively). Increases in subsequent periods (3-18 and >18 months) were also comparable across tiers. No differential CD4 gains across tiers were observed when the analysis was restricted to patients initiating ART under the GCR programme. INTERPRETATION & CONCLUSIONS: This ART delivery model was associated with significant CD4 gains with no observable difference by how much patients paid. Importantly, gains were comparable to those in other free rollout programmes. Additional cost-effectiveness analyses and mathematical modelling would be needed to determine whether such a delivery programme is a sustainable alternative to free ART programmes.

Adherence to antiretroviral therapy in patients participating in a graduated cost recovery program at an HIV care center in South India.

In resource-constrained settings, the most frequently cited barrier to optimal antiretroviral therapy (ART) adherence among HIV-infected patients has been the cost of medications. In recent years many subsidized medication programs have been developed to improve ART affordability. A Graduated Cost Recovery program at the largest care center in South India has enrolled 839 eligible patients into four tiers based on an evaluation of their financial information and willingness to pay, of these patients 635 consented to participate in this study. Patients in Tier 1 receive first-line ART at no cost, whereas patients in Tiers 2, 3, and 4 pay 50, 75, and 100%, respectively of the cost of first-line medications based on an assessment of their means. Adherence rates of 95% or greater on 3-day recall were achieved by 84.6% of Tier 1 (n = 156), 71.6% of Tier 2 (n = 141), 72.3% of Tier 3 (n = 242), and 79.2% of Tier 4 (n = 96). These findings suggest patients are highly motivated and that the provision of no-cost ART can promote higher rates of optimal adherence.
