Comparative evaluation of costs and healthcare resource utilization of oral selexipag versus inhaled treprostinil or oral treprostinil in patients with pulmonary arterial hypertension.

BACKGROUND: Pulmonary arterial hypertension (PAH), a rare vasculopathy progressively leading to right heart failure and death, is associated with considerable economic burden. Oral prostacyclin pathway agents (PPAs) like selexipag and treprostinil address an underlying PAH pathway, yet are often under-utilized. Data on head-to-head cost comparison of various PPAs is lacking. METHODS: In this retrospective study using a large health claims database, we compared the per-patient-per-year (PPPY) costs and healthcare resource utilization (HRU) among PAH patients taking either oral selexipag, inhaled treprostinil or oral treprostinil in the United States between July 2015 and March 2020. Patients with ≥1 prescription for one of the drugs of interest, ≥1 in-patient pulmonary hypertension (PH) diagnosis, or ≥ 2 outpatient PH diagnoses were included in this study. Baseline differences between the three groups were adjusted using an inverse probability of treatment weighting approach. 411 patients were selected for the final study cohorts. RESULTS: All-cause hospitalization costs were highest for oral treprostinil ($39,983) compared to oral selexipag ($20,635) and inhaled treprostinil ($16,548; p = .037). Total PAH-related medical costs were 40% lower for patients on oral selexipag compared to patients on oral and inhaled treprostinil ($24,351 vs. $40,398 and $40,339, respectively; p = .006). PAH-related outpatient visits were lowest for patients on oral selexipag (14 PPPY visits) compared to oral treprostinil (16 PPPY visits) and inhaled treprostinil (22 PPPY visits; p = .001). CONCLUSIONS: Compared to oral and inhaled treprostinil, oral selexipag may incur lower medical costs and reduce PAH related outpatient visits for patients with PAH.

Real-world analysis of insurance churn among young adults with schizophrenia using the Colorado All-Payer Claims Database.

BACKGROUND: Most patients with schizophrenia are diagnosed in their early twenties and often have commercial insurance at diagnosis. These young adults can experience changes in insurance coverage, that is, "churn," which can lead to disruptions in care. OBJECTIVE: To examine the frequency, speed, and type of insurance churn events in a young adult schizophrenia population with commercial insurance coverage at diagnosis. METHODS: The Colorado All-Payer Claims Database, containing insurance claims data from commercial and public insurers for Colorado residents, was used for the study. Eligible patients were required to have at least 1 inpatient or 2 outpatient claims for schizophrenia or schizoaffective disorder, be of age 18-34 years at index, have previous insurance coverage for 12 consecutive months, and have commercial insurance at diagnosis. These patients were 1:5 propensity score matched (PSM) with nonschizophrenia members. Percentages of members on different insurance types were calculated monthly to assess churn events. Cohorts were compared using descriptive statistics, Cox proportional hazards, and generalized estimating equation models. RESULTS: The matched schizophrenia and nonschizophrenia cohorts comprised 501 and 2,510 members, respectively. Before PSM, cohorts were imbalanced (schizophrenia cohort had a younger median age and higher proportion of males). After matching, the cohorts were similar in terms of the matched baseline characteristics. Previous mental health disorders were more common in the schizophrenia cohort (75%) than in the nonschizophrenia cohort (26%). The proportion of members with at least 1 churn event for the schizophrenia and nonschizophrenia cohorts, respectively, were 53.8% vs 36.5% after 12 months and 84.6% vs 69.2% after 48 months. Time to first churn event was significantly shorter in the schizophrenia cohort (16 months) than the nonschizophrenia cohort (23 months; P < 0.001). Schizophrenia cohort members had 64.1 and 56.8 churn events per 1,000 members per month vs 43.0 (P ≤ 0.001) and 42.8 (P = 0.011) churn events for nonschizophrenia cohort members in the first and second 6-month periods, respectively. Proportions of members in the schizophrenia and nonschizophrenia cohorts on public insurance, respectively, were 22.9% vs 6.9% after 12 months and 52.4% and 10.7% after 48 months. In the schizophrenia cohort, the most common churn event type was from commercial to public insurance rather than to a different commercial insurance; notably, 41% of members were still on a commercial plan 4 years after diagnosis. CONCLUSIONS: Young adults with schizophrenia experienced churn events more rapidly and more frequently than those without schizophrenia for the first 4 years studied after the index date. These disruptions may be associated with reduced access to care and treatment gaps in this vulnerable patient population. DISCLOSURES: This research was sponsored by Janssen Scientific Affairs, LLC.

Economic burden to commercial payers of young adults with schizophrenia in Colorado.

AIMS: The primary objective was to examine direct costs and health resource utilization (HRU) among commercially insured young adults with schizophrenia (SCZ) in Colorado. MATERIALS AND METHODS: The Colorado All-Payer Claims Database, covering approximately 76% of the insured Colorado population was used. Members aged 18-34, with and without SCZ, having commercial insurance were included. All-cause, mental health (MH) related and non-MH related per patient per month (PPPM) costs and per hundred patients per month (PHPPM) HRU were compared between an SCZ cohort and a propensity score matched non-SCZ cohort before and after index date up to 48 months. RESULTS: Five hundred and one patients with SCZ and 2,510 matched individuals without SCZ were included. HRU and costs were higher for SCZ patients both pre- and post-index date. Pre-index, there were 32.3 (24.0 MH; 8.4 non-MH) PHPPM more office visits; 2.1 (2.7 MH) PHPPM more admissions; 104.8 (67.02 MH; 37.7 non-MH) PHPPM more prescriptions in the SCZ cohort (all p<.01). After index date, the SCZ cohort had 89.6 (81.3 MH; 9.2 non-MH) more PHPPM office visits, 7.2 (6.1 MH; 0.9 non-MH) PHPPM more admissions, and 181.6 (123.1 MH; 58.6 non-MH) PHPPM more prescriptions (all p<.001). All-cause costs in the pre-index period were $457 PPPM ($373 MH) higher for the SCZ cohort (p<.001). In the post-index period, all-cause costs for the SCZ cohort were $1,687 PPPM ($1,258 MH; $412 non-MH) higher (all p<.001). Approximately, 40% of patients with SCZ were on commercial insurance after four years compared with approximately 75% in the non-SCZ cohort. LIMITATIONS: This study was based on data from a single state, thus may not be generalizable to other states. CONCLUSIONS: Healthcare costs and HRU for young adults diagnosed with SCZ are significantly more burdensome to commercial payers than matched patients without SCZ, both before and after an official SCZ diagnosis.

Avoidable Acute Care Use Associated with Nausea and Vomiting Among Patients Receiving Highly Emetogenic Chemotherapy or Oxaliplatin.

PURPOSE: Chemotherapy-induced nausea and vomiting (CINV) contributes to avoidable acute care, a metric now tracked in Medicare's oncology outcome measure. CINV is preventable, yet guidelines are often not followed. We sought to quantify acute care involving CINV and other avoidable toxicities after highly emetogenic chemotherapy (HEC) to identify excess risk and assess clinician adherence to antiemesis guidelines for HEC. MATERIALS AND METHODS: We retrospectively evaluated U.S. electronic health records (2012-2018) using Medicare's OP-35 outcome measure to identify avoidable acute care involving any of 10 toxicities, including CINV, after HEC regimens relative to non-HEC. Antiemetic guideline adherence was defined as use ofneurokinin-1 (NKl) receptor antagonists Q5 (RAs) plus 5-hydroxytryptamine type 3 RA+ dexamethasone at HEC initiation. RESULTS: Among 17,609 patients receiving HEC, acute care rates associated with HEC chemotherapy included 32% cisplatin, 31% carboplatin, and 21% anthracycline/cyclosphospharnide (AC), with 76% meeting the criteria as avoidable events. Oxaliplatin rates were 29%. Avoidable acute care occurred 1.83 times (95% confidence interval, 1.76-1.91, p < .0001) as often after HEC versus non-HEC excluding oxaliplatin; CINV-related acute care occurred 2.29 times as often. Nonadherence to antiemesis guidelines occurred in 34% and 24% of cisplatin and AC courses, respectively, because of omission of a NKl RA. CONCLUSIONS: Patients treated with HEC regimens experienced high avoidable acute care use, 1.8 times the risk seen for other chemotherapy. Nonadherence to guideline-directed antiemetic prophylaxis highlights the need to ensure adherence to antiemetic guidelines, including the use of NKl RA in HEC. IMPLICATIONS FOR PRACTICE: After survival, perhaps the most important goal in oncology is limiting avoidable acute care, a goal now used by Medicare to impact cancer reimbursement. This study found that patients treated with highly emetogenic chemotherapy (HEC) regimens had high rates of avoidable acute care use, 1.8 times the risk seen for other chemotherapy. A substantial proportion of the avoidable acute care involved chemotherapy-induced nausea and vomiting. Results showed that incomplete adherence to national antiemetic guidelines for HEC regimens primarily driven by omission of upfront neurokinin-1 receptor antagonist use, suggesting that improved adherence can meaningfully resolve this gap in quality and cost of care.

Early Marketplace Enrollees Were Older And Used More Medication Than Later Enrollees; Marketplaces Pooled Risk.

Little is known about the health status of the 7.3 million Americans who enrolled in insurance plans through the Marketplaces established by the Affordable Care Act in 2014. Medication use may provide an early indicator of the health needs and access to care among Marketplace enrollees. We used data from January-September 2014 on more than one million Marketplace enrollees from Express Scripts, the largest pharmacy benefit management company in the United States. We compared the characteristics and medication use between early and late Marketplace enrollees and between all Marketplace enrollees and enrollees with employer-sponsored insurance. Among Marketplace enrollees, we found that those who enrolled earlier (October 2013-February 2014) were older and used more medication than later enrollees. Marketplace enrollees, as a whole, had lower average drug spending and were less likely to use most medication classes than the employer-sponsored comparison group. However, Marketplace enrollees were more likely to use medicines for hepatitis C and particularly for HIV.
