Objective: To evaluate healthcare resource utilization (HRU) and costs among patients who initiated repository corticotropin injection (RCI; H.P. Acthar Gel) treatment for rheumatoid arthritis (RA) or systemic lupus erythematosus (SLE)., Methods: Patients aged ≥18 years with ≥2 diagnoses for either RA or SLE between July 1, 2006 and April 30, 2015 were identified in the HealthCore Integrated Research Database. Index RCI date was the earliest date of a medical or pharmacy claim for RCI after diagnosis. Baseline characteristics, pre- and post-initiation HRU and costs were assessed using descriptive statistics., Results: This study identified 180 RA patients (mean age = 60 years, 56% female) and 29 SLE patients (mean age = 45 years, 90% female) who initiated RCI. First RCI use averaged 7.1 and 22.6 months after the initial RA and SLE diagnosis, respectively. After RCI initiation, RA patients incurred significantly lower per-patient-per-month (PPPM) all-cause medical costs ($1,881 vs $682, p < .01) vs the pre-initiation period, driven by lower PPPM hospitalizations costs ($1,579 vs $503, p < .01). Overall PPPM healthcare costs were higher ($2,751 vs $5,487, p < .01) due to higher PPPM prescription costs ($869 vs $4,805, p < .01). Similarly, SLE patients had decreased PPPM hospitalization costs ($3,192 vs $799, p = .04) and increased PPPM prescription costs ($905 vs $7,443, p < .01) after initiating RCI; the difference in overall PPPM healthcare costs was not statistically significant likely, due to small sample size., Conclusion: This study, across a heterogeneous population of variable disease duration, described clinical and healthcare utilization and costs of RA and SLE patients initiating RCI in a real-world setting. We observed that patients receiving RCI had lower utilization and costs for medical services in both disease populations, which partially offset the increased prescription costs by 30% and 37%. Future research is needed to explore factors associated with RCI initiation and its impact on long-term outcomes.

Background: Sarcoidosis is a multi-system inflammatory disorder characterized by the presence of non-caseating granulomas in involved organs. Patients with sarcoidosis have a reduced quality-of-life and are at an increased risk for several comorbidities. Little is known about the direct and indirect cost of sarcoidosis following the initial diagnosis., Aims: To provide an estimate of the healthcare resource utilization (HCRU) and costs borne by commercial payers for sarcoidosis patients in the US., Methods: Patients with a first diagnosis of sarcoidosis between January 1, 1998 and March 31, 2015 ("index date") were selected from a de-identified privately-insured administrative claims database. Sarcoidosis patients were required to have continuous health plan enrollment 12 months prior to and following their index dates. Propensity-score (1:1) matching of sarcoidosis patients with non-sarcoidosis controls was carried out based on a logistic regression of baseline characteristics. Burden of HCRU and work loss (disability days and medically-related absenteeism) were compared between the matched groups over the 12-month period following the index date ("outcome period")., Results: A total of 7,119 sarcoidosis patients who met the selection criteria were matched with a control. Overall, commercial payers incurred $19,714 in mean total annual healthcare costs per sarcoidosis patient. The principle cost drivers were outpatient visits ($9,050 2015 USD, 46%) and inpatient admissions ($6,398, 32%). Relative to controls, sarcoidosis patients had $5,190 (36%) higher total healthcare costs ($19,714 vs $14,524; p < 0.001). Sarcoidosis patients also had significantly more work loss days (15.9 vs 11.3; p < 0.001) and work loss costs ($3,288 vs $2,527; p < 0.001) than matched controls. Sarcoidosis imposes an estimated total direct medical cost of $1.3-$8.7 billion to commercial payers, and an indirect cost of $0.2-$1.5 billion to commercial payers in work loss., Conclusions: Sarcoidosis imposes a significant economic burden to payers in the first year following diagnosis.

Objective: The objective for the research was to evaluate the direct healthcare costs for Crohn's disease (CD) patients categorized by adherence status., Methods: Adult patients with ≥1 claim for infliximab and ≥2 claims for CD who were continuously insured for 12 months before and after their first infliximab infusion (index date) were identified in a 2006-2009 US managed care database. Patients were excluded if they had rheumatoid arthritis claims, received infliximab billed as a pharmacy benefit, or received another biologic drug. Patients were categorized as being either adherent or intermittently adherent to infliximab using a pre-defined algorithm. Total and component direct costs, CD-related costs, rates of surgery, and days of hospitalization were estimated for the 360-day post-index period. Propensity weighted generalized linear models were used to adjust the cost estimates for potential confounding variables., Results: The total propensity weighted cost for infliximab adherent patients was $40,425 (95% CI = [$38,686, $42,242]), compared to $41,082 (95% CI = [$38,163, $44,223]) for the intermittently adherent (p = 0.71). However, adherent patients had lower total direct medical costs, exclusive of infliximab, that were $13,097 (95% CI = [$12,141, $14,127]) compared with $20,068 (95% CI = [$17,676, $22,784]) for intermittently adherent patients as a result of substantially lower hospital and outpatient costs (p < 0.0001)., Conclusions: Greater drug-related costs for infliximab adherent patients were offset by lower costs from hospitalization and outpatient visits. These findings indicate that adherent patients have improved clinical outcomes, at a similar aggregate cost, than patients who are only intermittently adherent to therapy.

Objective: Healthcare costs of inflammatory bowel disease are substantial. This study examined the effect of adherence versus non-adherence on healthcare costs in patients with inflammatory bowel disease., Methods: Adults who started infliximab treatment between 2006 and 2009 and had a diagnosis of inflammatory bowel disease were identified from MarketScan Databases. Medication adherence was defined as an infliximab medication possession ratio of 80% or greater in the first year. Mean treatment effects (adherence versus non-adherence) on costs in adherent patients were estimated with propensity-weighted generalized linear models., Results: A total of 1646 patients were identified. Significant variables in the model used to develop propensity weights were age, year of infliximab initiation, having Medicare coverage, presence of supplementary diagnoses, office as the place of service for infliximab initiation, prior aminosalicylate use, prior outpatient costs, number of prior outpatient visits, and number of prior colonoscopies. Mean total costs in adherent (n = 674) and propensity-weighted non-adherent (n = 972) patients were $41,713 versus $47,411 overall (p < 0.001), including $28,289 versus $14,889 for infliximab drug costs (p < 0.001), $2458 versus $17,634 for hospitalizations (p < 0.001), $7357 versus $10,909 for outpatient visits (p < 0.001), $236 versus $458 for emergency room visits (p < 0.001), and $3373 versus $3521 for other pharmaceuticals costs (p = 0.460)., Limitations: Costs associated with infliximab administration (infusions, adverse events) were captured in healthcare costs (inpatient, outpatient, and emergency room), not in infliximab costs. The influence of adherence on indirect costs (e.g., time lost from work) could not be determined. Reasons for non-adherence were not available in the database., Conclusions: In patients who were adherent to infliximab treatment (a medication possession ratio of 80% or greater in the first year), adherence versus non-adherence was associated with lower total healthcare costs, supporting the overall value of infliximab adherence in patients with inflammatory bowel disease.
