The clinical and economic burdens of metabolic dysfunction-associated steatohepatitis

Aims This study aimed to assess and compare the health care resource utilization (HCRU) and medical cost of metabolic dysfunction-associated steatohepatitis (MASH) by disease severity based on Fibrosis-4 Index (FIB-4) score among US adults in a real-world setting. Materials and methods This observational cohort study used claims data from the Healthcare Integrated Research Database (HIRD) to compare all-cause, cardiovascular (CV)-related, and liver-related HCRU, including hospitalization, and medical costs stratified by FIB-4 score among patients with MASH (identified by International Classification of Diseases, Tenth Revision, Clinical Modification [ICD-10-CM] code K75.81). Hospitalization and medical costs were compared by FIB-4 score using generalized linear regression with negative binomial and gamma distribution models, respectively, while controlling for confounders. Results The cohort included a total of 5,104 patients with MASH and comprised 3,162, 1,343, and 599 patients with low, indeterminate, and high FIB-4 scores, respectively. All-cause hospitalization was significantly higher in the high FIB-4 cohort when compared with the low FIB-4 reference after covariate adjustment (rate ratio, 1.63; 95% CI, 1.32-2.02; P<.0001). CV-related hospitalization was similar across all cohorts; however, CV-related costs were 1.26 times higher (95% CI, 1.11-1.45; P<.001) in the indeterminate cohort and 2.15 times higher (95% CI, 1.77-2.62; P<.0001) in the high FIB-4 cohort when compared with the low FIB-4 cohort. Patients with indeterminate and high FIB-4 scores had 2.97 (95% CI, 1.78-4.95) and 12.08 (95% CI, 7.35-19.88) times the rate of liver-related hospitalization and were 3.68 (95% CI, 3.11-4.34) and 33.73 (95% CI, 27.39-41.55) times more likely to incur liver-related costs, respectively (P<.0001 for all). Limitations This claims-based analysis relied on diagnostic coding accuracy, which may not capture the presence of all diseases or all care received. Conclusions High and indeterminate FIB-4 scores were associated with significantly higher liver-related clinical and economic burdens than low FIB-4 scores among patients with MASH.

Estimating the health care costs associated with receipt of lisocabtagene maraleucel: Insights from adults with mantle cell lymphoma (TRANSCEND NHL 001).

7028 Background: Anti-CD19 CAR T cell therapy is a major advancement for treating R/R B-cell malignancies such as mantle cell lymphoma (MCL). While effective disease management with CAR T cell therapy is expected to reduce patients’ health care resource utilization (HCRU) over the long-term, few studies have examined the short-term impacts of this treatment on HCRU and associated health care costs. Here, we used data from the TRANSCEND NHL 001 (NCT02631044) clinical trial to estimate the HCRU-related costs incurred by patients with R/R MCL over the first 12 months after receipt of lisocabtagene maraleucel (liso-cel). Methods: A retrospective analysis of clinical trial data was conducted to calculate the frequency of HCRU (medications [excluding liso-cel], diagnostics, procedures, ICU and non-ICU hospitalizations) observed over the 12 months immediately after administration of liso-cel. Costs for each HCRU event were derived from public databases and literature, adjusted to 2023 United States (US) dollars, and used to estimate patient-level health care costs. Results: Of the patients treated (N = 88), 76.1% were male, 87.5% were White, and mean ± standard deviation (SD) age was 67.5 ± 9 years. All patients were treated in the US and completed a median (range) of 3 (1–11) prior lines of therapy before receiving liso-cel. Most patients (93.2%) received the recommended dose of 100 × 106 CAR+ T cells. The total mean ± SD per-patient cost (excluding liso-cel) was estimated at $138,413 ± $58,555 over 12 months. Facility use accounted for 77.7% of all costs, primarily owing to non-ICU hospitalizations (98.9%), which had a mean ± SD length of stay of 19.5 ± 16.7 days per eligible patient. Half of all health care costs were incurred within the first month of infusion (53.2%), with each subsequent month contributing a fraction (1.5%–6.3%) of total costs. A total of 13 out of 88 patients received their initial infusion in an outpatient setting and incurred 23% fewer costs compared with those who received their infusion in an inpatient setting ($110,050 vs $143,418), primarily as a function of reduced first-month facility use. Total costs for patients receiving liso-cel in outpatient settings were further reduced to $72,771 upon exclusion of 3 outliers. Conclusions: Non-ICU hospitalizations were the largest driver of liso-cel–related costs in this R/R MCL cohort of clinical trial participants. Most of the cost burden was incurred within 1 month of treatment, with dramatic reductions in HCRU and health care costs observed thereafter. Results suggest that treatment in the outpatient setting, even in part (eg, at initial infusion only), may confer substantial cost savings to the health care system.

Healthcare resource utilization and costs in patients with a newly confirmed diagnosis of lupus nephritis in the United States over a 5-year follow-up period

BackgroundWe aimed to describe healthcare resource utilization (HCRU) and healthcare costs in patients with newly confirmed lupus nephritis (LN) in the United States over a 5-year follow-up period.MethodsThis retrospective, longitudinal cohort study (GSK Study 214102) utilized administrative claims data to identify individuals with a newly confirmed diagnosis of LN between August 01, 2011, and July 31, 2018, based on LN-specific International Classification of Diseases diagnosis codes. Index was the date of first LN-related diagnosis code claim. HCRU, healthcare costs, and incidence of systemic lupus erythematosus (SLE) flares were reported annually among eligible patients with at least 5 years continuous enrollment post-index.ResultsOf 2,159 patients with a newly confirmed diagnosis of LN meeting inclusion and exclusion criteria, 335 had at least 5 years continuous enrollment post-index. HCRU was greatest in the first year post-LN diagnosis across all categories (inpatient admission, emergency room [ER] visits, ambulatory visits, and pharmacy use), and trended lower, though remained substantial, in the 5-year follow-up period. Among patients with LN and HCRU, the mean (standard deviation [SD]) number of ER visits and inpatient admissions were 3.7 (4.6) and 1.8 (1.5), respectively, in Year 1, which generally remained stable in Years 2–5; the mean (SD) number of ambulatory visits and pharmacy fills were 35.8 (25.1) and 62.9 (43.8), respectively, in Year 1, and remained similar for Years 2–5. Most patients (≥ 91.6%) had ≥ 1 SLE flare in each of the 5 years of follow-up. The proportion of patients who experienced a severe SLE flare was higher in Year 1 (31.6%) than subsequent years (14.3–18.5%). Total costs (medical and pharmacy; mean [SD]) were higher in Year 1 ($44,205 [71,532]) than subsequent years ($29,444 [52,310]–$32,222 [58,216]), driven mainly by inpatient admissions (Year 1: $21,181 [58,886]; subsequent years: $7,406 [23,331]–$9,389 [29,283]).ConclusionsPatients with a newly confirmed diagnosis of LN have substantial HCRU and healthcare costs, particularly in the year post-diagnosis, largely driven by inpatient costs. This highlights the need for improved disease management to prevent renal damage, improve patient outcomes, and reduce costs among patients with renal involvement.

#2533 Real-world challenges associated with the use of systemic glucocorticoids in a US IgAN cohort

Abstract Background and Aims Immunoglobulin A nephropathy (IgAN) is the most common primary glomerular disease and up to 50% of patients progress to kidney failure within 10-20 years. Until early 2022, management of IgAN was primarily focused on supportive care. As outlined in the Kidney Disease: Improving Global Outcomes (KDIGO) guidelines, patients at high risk of progressive chronic kidney disease despite maximal supportive care can be considered for a 6-month course of systemic glucocorticoids (SGC), although important risks of toxicity and contraindications must be considered. There is currently limited real-world evidence describing the impact of the use of SGC on treatment‑emergent toxicity and healthcare resource utilization (HCRU) in patients with IgAN. We report the incidence of adverse events (AEs) commonly associated with SGC, as well as HCRU rates and costs, in a real-world cohort of IgAN patients, comparing new initiators of SGC with patients who have never initiated SGC. Method This non-interventional, retrospective cohort study was conducted in the TriNetX Dataworks - United States of America Network, a database of de-identified, patient-level electronic medical records (EMR) of approximately 100 million patients. The cohort was selected from a total of 19, 687 patients with IgAN, identified using proxy ICD‑10 codes N02.8 (recurrent and persistent hematuria with other morphologic changes) or N04.1 (nephrotic syndrome) between January 1, 2011, and May 4, 2022. Eligible patients were required to have: an incident diagnosis of IgAN with the same diagnosis within 30-180 days; at least 12 months of EMR history available prior to and after initial IgAN diagnosis; not experienced kidney failure prior to or on the initial date of IgAN diagnosis; and not received SGC prior to the date of diagnosis. Data assessed included demographic and clinical characteristics, IgAN-directed medications, AEs, and HCRU. To promote balance between cohorts, new initiators of SGC (dexamethasone, prednisone, prednisolone, methylprednisolone) were matched with patients who did not receive SGC using a propensity score (PS) approach based on their characteristics at diagnosis. To avoid immortal-time bias, the index date was set as the time of SGC initiation in patients in the SGC cohort; for the non-SGC cohort, a pseudo-index date was assigned using the same lag from diagnosis to index date as their 1:1 PS-matched patient in the SGC cohort. Differences in the cumulative incidence of individual AEs were analyzed using the chi-square test or Fisher's exact test, and differences in HCRU rates and costs were analyzed using the Kruskal-Wallis test. Results After implementing the PS approach, the final analysis included 802 patients (401 PS-matched pairs), with a mean age of 41.2 years and 55% being male. Median duration of follow-up was 3.5 and 3.1 years for the SGC and non-SGC cohorts, respectively. Of AEs that occurred in at least ten of the 802 patients, patients who received SGC experienced a significantly increased incidence of all AEs except for fractures, new onset of diabetes, and reported onset of glaucoma (Table 1). Patients who received SGC had a 12-fold increased incidence of severe infections requiring hospitalization compared with the non-SGC cohort. Annualized mean HCRU rates and costs were significantly greater across all HCRU types for patients who received SGC vs those who did not receive SGC, including an 8-fold increase in inpatient visits, a 4-fold increase in emergency department admissions, and twice as many ambulatory visits (Fig. 1). Results were consistent when the cohort was restricted to patients with IgAN identified using only the ICD-10 code N02.8 (recurrent and persistent hematuria with other morphologic changes). Conclusion The findings of this real-world analysis demonstrate significant side effects and costs for IgAN patients treated with SGC compared with patients not treated with SGC, underscoring the recommendation in the 2021 KDIGO guidelines to carefully consider treatment-emergent toxicity before treating IgAN patients with SGC.

Healthcare resource utilization and costs among patients with alpha-1 antitrypsin deficiency with liver and/or lung disease: a longitudinal retrospective study in the USA.

Aim: To evaluate all-cause and liver-associated healthcare resource utilization (HCRU) and costs among patients with alpha-1 antitrypsin deficiency (AATD) with liver disease (LD) and/or lung disease (LgD). Materials & methods: This was a retrospective analysis of linked administrative claims data from the IQVIA PharMetrics® Plus and the IQVIA Ambulatory Electronic Medical Records (AEMR) databases from 1July2021 to 31January 2022. Patients with AATD in the IQVIA PharMetrics Plus database were included with ≥1 inpatient or ≥2 outpatient medical claims ≥90days apart with a diagnosis of AATD, or with records indicating a protease inhibitor (Pi)*ZZ/Pi*MZ genotype in the IQVIA AEMR database with linkage to IQVIA PharMetrics Plus. For a patient's identified continuous enrollment period, patient time was assigned to health states based on the initial encounter with an LD/LgD diagnosis. A unique index date was defined for each health state, and HCRU and costs were calculated per person-year (PPY). Results: Overall, 5136 adult and pediatric patients from the IQVIA PharMetrics Plus and IQVIA AEMR databases were analyzed. All-cause and liver-associated HCRU and costs were substantially higher following onset of LD/LgD. All-cause cost PPY ranged from US $11,877 in the absence of either LD/LgD to US $74,015 in the presence of both LD and LgD. Among liver transplant recipients in the AATD with LD health state, liver-associated total costs PPY were US $87,329 1-year pre-transplantation and US $461,752 1-year post-transplantation. In the AATD with LgD and AATD with LD and LgD health states, patients who received augmentation therapy were associated with higher all-cause total costs PPY and lower liver-associated total costs PPY than their counterparts who did not receive augmentation therapy. Conclusion: Patients with AATD had increased HCRU and healthcare costs in the presence of LD and/or LgD. HCRU and healthcare costs were highest in the AATD with LD and LgD health state.

Economic Burden of Itch-Related Sleep Loss in Moderate-to-Severe Atopic Dermatitis in the United Kingdom.

Atopic dermatitis is associated with intense itch, which has been shown to cause sleep disruption that significantly impacts the lives of patients with atopic dermatitis. Despite this, little is known about its burden to the healthcare system and society. This study aimed to quantify the economic burden of itch-related sleep loss in moderate-to-severe atopic dermatitis in the UK. A literature-based decision-analytic model was developed from a healthcare payer and societal perspective. The model quantifies the economic burden by linking the severity of itch to the number of days of sleep disruption. The model captures the direct costs of healthcare resource utilization and treatment alongside the indirect costs of productivity loss from absenteeism and presenteeism at work over a 5-year time horizon. The patient population considered was patients aged ≥ 15 years with moderate-to-severe atopic dermatitis and itch-related sleep disruption. The model estimated that itch-related sleep disruption as a result of moderate-to-severe atopic dermatitis would affect an average of 821,142 people over the time horizon (2022 to 2026). This translates into an average net economic burden of £3.8 billion (£4687 per patient), with an average of 172 million days being affected by sleep disruption per year in the UK. The greatest contributor to the annual average net economic burden was productivity loss from absenteeism and presenteeism, each accounting for 34%. The direct costs (treatment costs and healthcare resource use) accounted for 32% of the net economic burden. The results showed a high and gradually increasing economic burden over the 5-year time horizon. Sleep disruption has a high economic burden and reducing itch may provide substantial direct and indirect savings. Quantifying the economic burden of itch-related sleep loss may provide support for analyses to inform public health policies for treatment of atopic dermatitis, particularly within the moderate-to-severe level.

Healthcare resource utilisation and direct medical cost for individuals with 5q spinal muscular atrophy in Sweden.

Spinal muscular atrophy (SMA) is a rare, progressive, neuromuscular disorder. Recent advances in treatment require an updated assessment of burden to inform reimbursement decisions. To quantify healthcare resource utilisation (HCRU) and cost of care for patients with SMA. Cohort study of patients with SMA identified in the Swedish National Patient Registry (2007-2018), matched to a reference cohort grouped into four SMA types (1, 2, 3, unspecified adult onset [UAO]). HCRU included inpatient admissions, outpatient visits, procedures, and dispensed medications. Direct medical costs were estimated by multiplying HCRU by respective unit costs. Average annual HCRU and medical costs were modelled for SMA versus reference cohorts to estimate differences attributable to the disease (i.e., average treatment effect estimand). The trajectory of direct costs over time were assessed using synthetic cohorts. We identified 290 SMA patients. Annualised HCRU was higher in SMA patients compared with reference cohorts. Highest risk ratios were observed for inpatient overnight stays for type 1 (risk ratio [RR]: 29.2; 95% confidence interval [CI]: 16.0, 53.5) and type 2 (RR: 23.3; 95% CI: 16.4,33.1). Mean annual direct medical costs per patient for each year since first diagnosis were greatest for type 1 (€114,185 and SMA-attributable: €113,380), type 2 (€61,876 and SMA-attributable: €61,237), type 3 (€45,518 and SMA-attributable: €44,556), and UAO (€4046 and SMA-attributable: €2098). Costs were greatest in the 2-3years after the first diagnosis for all types. The economic burden attributable to SMA is significant. Further research is needed to understand the burden in other European countries and the impact of new treatments.

Reduction in Diabetes-Related Hospitalizations and Medical Costs After Dexcom G6 Continuous Glucose Monitor Initiation in People with Type 2 Diabetes Using Intensive Insulin Therapy.

Some people with type 2 diabetes (T2D) require intensive insulin therapy to manage their diabetes. This can increase the risk of diabetes-related hospitalizations. We hypothesize that initiation of real-time continuous glucose monitoring (RT-CGM), which continuously measures a user's glucose values and provides threshold- and trend-based alerts, will reduce diabetes-related emergency department (ED) and inpatient hospitalizations and concomitant costs. A retrospective analysis of US healthcare claims data using Optum's de-identified Clinformatics® Data Mart database was performed. The cohort consisted of commercially insured, CGM-naïve individuals with T2D who initiated Dexcom G6 RT-CGM system between August 1, 2018, and March 31, 2021. Twelve months of continuous health plan enrollment before and after RT-CGM initiation was required to capture baseline and follow-up rates of diabetes-related hospitalizations and associated healthcare resource utilization (HCRU) costs. Analyses were performed for claims with a diabetes-related diagnosis code in either (1) any position or (2) first or second position on the claim. A total of 790 individuals met the inclusion criteria. The average age was 52.8 (10.5) [mean (SD)], 53.3% were male, and 76.3% were white. For claims with a diabetes-related diagnosis code in any position, the number of individuals with ≥ 1 ED visit decreased by 30.0% (p = 0.01) and with ≥ 1 inpatient visit decreased by 41.5% (p < 0.0001). The number of diabetes-related visits and average number of visits per person similarly decreased by at least 31.4%. Larger relative decreases were observed for claims with a diabetes-related diagnosis code in the first or second position on the claim. Total diabetes-related costs expressed as per-person-per-month (PPPM) decreased by $341 PPPM for any position and $330 PPPM for first or second position. Initiation of Dexcom G6 among people with T2D using intensive insulin therapy was associated with a significant reduction in diabetes-related ED and inpatient visits and related HCRU costs. Expanded use of RT-CGM could augment these benefits and result in further cost reductions.

Patterns of care and costs of switching oral antipsychotic medications in patients with schizophrenia initiating monotherapy treatment: A US claims analysis.

Antipsychotic medications are the mainstay of schizophrenia therapy but may need to be changed over the course of a patient's illness to achieve the desired therapeutic goals or minimize medication side effects. Investigations of real-world treatment patterns and economic consequences associated with antipsychotic changes, including switching, are limited. To describe treatment patterns among patients with schizophrenia who initiated oral antipsychotic medication (OAM) monotherapy and assess switching-related health care resource utilization (HCRU) and costs in US Medicare Advantage and commercially insured patients. Adults with at least 2 claims with a schizophrenia diagnosis who initiated (or reinitiated after ≥6 months) OAM monotherapy between January 1, 2015, and June 30, 2021, were identified in the Optum Research Database. A claims-based algorithm using timing of therapies and treatment gaps identified medication changes, specifically OAM monotherapy switches, among OAM initiators over a period of up to 7 years. Patients who switched from their initial OAM monotherapy to a second OAM monotherapy (initial OAM switchers) were matched based on clinical and demographic characteristics to OAM initiators who had not switched OAMs; switch-related HCRU and costs (incurred up to 3 months before and 3 months after the initial OAM switch) were compared between matched initial OAM switchers and nonswitchers. Among 6,425 OAM monotherapy initiators, 1,505 (23.4%) had at least 1 OAM monotherapy switch at any time during follow-up, with a mean (SD) time to first switch of 209 (333) days (median, 67 days), a rate of 0.65 switches per person-year of follow-up, and 56% of first switches occurring within 3 months of OAM initiation. Of all OAM initiators, 947 (14.7%) were initial OAM switchers. Compared with 865 matched nonswitchers, 865 initial OAM switchers had greater mean counts of all-cause medical visits and greater mean counts of schizophrenia-related emergency and inpatient visits and longer inpatient stays per patient per month. Mean (SD) total schizophrenia-related costs per patient per month were $1,252 ($2,602) for switchers compared with $402 ($2,027) for nonswitchers (P < 0.001). Changes to antipsychotic therapy in our sample of patients with schizophrenia were common, with nearly one-fourth switching OAMs, the majority within the first 3 months of therapy. Initial OAM switchers experienced greater HCRU and costs than nonswitchers. These findings highlight the importance of initiating OAM monotherapy that effectively maintains symptom control and minimizes tolerability issues, which would limit the need to switch OAMs and therefore prevent excess HCRU and treatment costs.

Racial and Ethnic Disparities in Health-Related Outcomes in Crohn's Disease: Results From the National Health and Wellness Survey.

Crohn's disease (CD) is a chronic inflammatory condition affecting the entire gastrointestinal tract that is associated with significant humanistic, clinical, and economic burdens. Few studies have assessed the association between CD severity and patient-reported outcomes (PROs), healthcare resource utilization (HCRU), and medical costs; even fewer have examined differences in disease outcomes among patients of various racial/ethnic groups. In this cross-sectional study, sociodemographic data, PROs, and economic outcomes for participants with self-reported CD were collected from the National Health and Wellness Survey (2018-2020). Multivariable analyses were used to assess the association of CD severity and race/ethnicity with health-related quality of life (HRQoL), work productivity and activity impairment (WPAI), HCRU, and medical costs. Analyses included 1077 participants with CD (818 non-Hispanic White, 109 non-Hispanic Black, and 150 Hispanic). Participants with self-reported moderate/severe CD reported significantly worse HRQoL and WPAI, greater HCRU, and higher medical costs than those with self-reported mild CD. Non-Hispanic Black participants reported better HRQoL and fewer healthcare provider visits than non-Hispanic White participants. There were no significant differences in PROs between non-Hispanic White and Hispanic groups. Interactions between race/ethnicity and CD severity emerged for some, but not all groups: Specifically, non-Hispanic Black participants with moderate/severe CD reported greater absenteeism and more gastroenterologist visits than non-Hispanic Black participants with mild CD. Participants with moderate/severe CD reported worse PROs, greater HCRU, and higher medical costs than those with mild CD. Additionally, racial/ethnic differences were found across several HCRU and economic outcomes. Further research is needed to better understand factors contributing to burden among patients with varying CD severity across racial/ethnic groups.

P912 A Real-World Evidence Study of Dose Escalation and associated costs of advanced therapies for Ulcerative Colitis in France and United Kingdom

Abstract Background Dose escalation to optimize advanced therapies is common practice in ulcerative colitis (UC) to avoid intra-class or inter-class drug switching and maintain clinical response. Dose escalation also has impact on healthcare resource utilization (HRU) and costs. However, there are limited data available on real-life dose-escalation. Study aim was to understand real-world dose escalation/de-escalation UC advanced therapy drugs patterns in two European countries (France, United Kingdom [UK]). Methods This retrospective study analysed data from the THIN®/CEGEDIM database to identify adult patients with moderate-to-severe UC who were naïve to advanced UC therapies or had not received any of the UC advanced therapy drugs of interest (adalimumab [ADA], golimumab [GOL], infliximab [INF], tofacitinib [TOF], ustekinumab [UST], or vedolizumab [VED]) for at least 12 months prior first prescription (and/or dispensation for France) between January 2017 and February 2022. A dose increase of ≥20% during the maintenance period compared to lowest Summary of Product Characteristics recommended dose was considered dose escalation. Proportions of patients with dose escalation after maintenance date were estimated using Kaplan-Meier (KM) survival analyses. Clinical response (defined as absence of: UC-related hospitalization or colectomy, treatment switch or addition of another UC advanced drug, systemic/rectal corticosteroids exposure), and direct (consultations, hospitalisations, diagnostic tests, UC drugs, complementary therapy) and indirect costs related to UC by treatment cohort were also analysed. Results 1663 patients fulfilled the selection criteria, of whom 619 had information on dose patterns. Overall, 89% of patients (range 33% [INF] to 100% [GOL, TOF, and UST]) had dose escalation within the first 24 months after start of maintenance, with a median % dose increase ranging from +15% [VED] to +198% [GOL] (Table). Median (95% CI) time to first dose escalation was 2.1 (1.8-2.4) months (range 0.7 [UST] to 4.6 [VED]). Clinical response ranged from 56.3% (ADA) to 77.0% (INF). Direct annual HRU costs related to UC ranged from 3,085 (INF) to 16,527 (UST) EUR in France and from 1,857 (INF) to 4,104 (VED) GBP in the UK. Mean direct HRU costs in France were 25% higher in escalated patients compared to de-escalated patients (range: +4.2% GOL to +61.9% UST). Conclusion Dose escalation of advanced therapies for UC is a common strategy to avoid treatment-switching. Despite dose escalations and their cost to the system, a proportion of patients fail to achieve clinical response, highlighting the need for more efficacious and durable treatments for patients with moderate-to-severe UC.

Cytomegalovirus related hospitalization costs among hematopoietic stem cell and solid organ transplant recipients treated with maribavir versus investigator-assigned therapy: A US-based study.

Cytomegalovirus (CMV) infections among hematopoietic stem cell transplant (HSCT) and solid organ transplant (SOT) recipients impose a significant health care resource utilization (HCRU)-related economic burden. Maribavir (MBV), a novel anti-viral therapy (AVT), approved by the United States Food and Drug Administration for post-transplant CMV infections refractory (with/without resistance) to conventional AVTs has demonstrated lower hospital length of stay (LOS) versus investigator-assigned therapy (IAT; valgancilovir, ganciclovir, foscarnet, or cidofovir) in a phase 3 trial (SOLSTICE). This study estimated the HCRU costs of MBV versus IAT. An economic model was developed to estimate HCRU costs for patients treated with MBV or IAT. Mean per-patient-per-year (PPPY) HCRU costs were calculated using (i) annualized mean hospital LOS in SOLSTICE, and (ii) CMV-related direct costs from published literature. Probabilistic sensitivity analysis with Monte-Carlo simulations assessed model robustness. Of 352 randomized patients receiving MBV (n = 235) or IAT (n = 117) for 8 weeks in SOLSTICE, 40% had HSCT and 60% had SOT. Mean overall PPPY HCRU costs of overall hospital-LOS were $67,205 (95% confidence interval [CI]: $33,767, $231,275) versus $145,501 (95% CI: $62,064, $589,505) for MBV and IAT groups, respectively. Mean PPPY ICU and non-ICU stay costs were: $32,231 (95% CI: $5,248, $184,524) versus $45,307 (95% CI: $3,957, $481,740) for MBV and IAT groups, and $82,237 (95% CI: $40,397, $156,945) MBV versus $228,329 (95% CI: $94,442, $517,476) for MBV and IAT groups, respectively. MBV demonstrated cost savings in over 99.99% of simulations. This analysis suggests that Mean PPPY HCRU costs were 29%-64% lower with MBV versus other-AVTs.

Clinical characteristics and healthcare resource utilization in patients with chronic obstructive pulmonary disease in Hong Kong

ObjectivesChronic obstructive pulmonary disease (COPD) is a significant cause of mortality, with its prevalence projected to rise in Asia. The primary objective of this study was to describe clinical characteristics, maintenance treatment, and healthcare resource utilization (HCRU) among patients with COPD in Hong Kong. Secondary objectives were to assess patient demographics and clinical characteristics by eosinophil (EOS) levels, and compare the demographics, clinical characteristics, and treatment patterns of patients on multiple-inhaler triple therapy (MITT). MethodsThis study analyzed a cohort of patients with COPD who had entered a previously initiated prospective cohort study involving patients with COPD and/or asthma at the Prince of Wales Hospital between 2017 and 2019. ResultsPatients with COPD were enrolled (N = 220, mean age 74.3 years, 97 % male). Twelve months prior to baseline assessment, 66 % of patients were on MITT, 17 % on long-acting muscarinic antagonists (LAMAs)/long-acting beta-agonists (LABAs), and 7 % on inhaled corticosteroids (ICS)/LABA. Compared with ICS/LABA or LAMA/LABA, more patients on MITT experienced ≥1 exacerbation (26.7 %, 10.5 %, 39.7 %, respectively). Patients on MITT also had a higher mean (SD) COPD Assessment Test score (9.4 [5.9]) and modified Medical Research Council Dyspnea Scale score (1.7 [0.7]) and incurred the most COPD-related and total HCRU costs. Compared with patients with EOS ≤300 cells/μL, those with EOS >300 cells/μL had a higher number of exacerbations. ConclusionsPatients with COPD in Hong Kong treated with MITT presented more severe disease profiles and incurred higher costs. These data can be used for decision making in patients with moderate-to-severe COPD in Hong Kong.

Outcomes Following Initiation of Triple Therapy with Fluticasone Furoate/Umeclidinium/Vilanterol versus Multiple-Inhaler Triple Therapy Among Medicare Advantage with Part D Beneficiaries and Those Commercially Enrolled for Health Care Insurance in the United States.

Patients with chronic obstructive pulmonary disease (COPD) have been shown to benefit from triple therapy commonly delivered by multiple-inhaler triple therapy (MITT); however, the complexity of MITT regimens may decrease patient adherence. Fluticasone furoate/umeclidinium/vilanterol (FF/UMEC/VI), a once-daily single-inhaler triple therapy (SITT), became available in the United States (US) in 2017, but real-world data comparing outcomes for SITT versus MITT are currently limited. This study compared outcomes among patients with COPD initiating MITT versus SITT with FF/UMEC/VI who were either Medicare Advantage with Part D (MAPD) beneficiaries or commercial enrollees in the US. Retrospective study using administrative claims data from the Optum Research Database for patients with COPD who initiated FF/UMEC/VI or MITT between September 1, 2017, and March 31, 2019 (index date: first pharmacy claim for FF/UMEC/VI cohort; earliest day of ≥30 consecutive days-long period of overlap in the day's supply of all triple therapy components for MITT cohort). COPD exacerbations, adherence to triple therapy, and all-cause and COPD-related health care resource utilization (HCRU) and costs were compared between FF/UMEC/VI and MITT initiators. In total, 4659 FF/UMEC/VI initiators and 9845 MITT initiators for the MAPD population, and 821 FF/UMEC/VI initiators and 1893 MITT initiators for the commercial population were included in the study. MAPD beneficiaries initiating FF/UMEC/VI had a significantly lower annual rate of severe exacerbations compared to MITT initiators (0.26 vs 0.29; p=0.014). They also had a significantly higher mean adherence (proportion of days covered) (0.51 vs 0.37; p<0.001) and significantly lower all-cause and COPD-related inpatient stays compared to MITT initiators ([32.02% vs 34.27%; p=0.017], [16.09% vs 17.72%; p=0.037]). Trends were similar among the commercial population, but the results were not statistically significant. FF/UMEC/VI initiators had significantly fewer severe exacerbations, higher triple therapy adherence, and lower HCRU costs compared to MITT initiators for MAPD beneficiaries.

Healthcare resource utilization and healthcare costs in patients with type 2 diabetes mellitus initiating sodium-glucose cotransporter 2 inhibitors vs dipeptidyl peptidase-4 inhibitors in Japan: A real-world administrative database analysis.

Healthcare resource utilization (HCRU) and healthcare costs are important factors to consider when selecting appropriate treatment for type 2 diabetes mellitus. We compared the HCRU and healthcare costs of sodium-glucose cotransporter 2 inhibitors (SGLT2i) vs dipeptidyl peptidase-4 inhibitors (DPP4i) in patients with type 2 diabetes mellitus in Japan. This was a Japanese retrospective cohort study conducted using the JMDC Claims Database (January 1, 2015-December 31, 2021). Patients newly treated with an SGLT2i (31,872 patients) or a DPP4i (73,279 patients) were matched 1:1, using propensity score, after excluding patients without continuous SGLT2i or DPP4i prescriptions after the index date. HCRU and healthcare costs were compared between the treatment groups in the full cohort and subcohorts/subgroups of different baseline characteristics, including body mass index (BMI). After matching, patient characteristics were well balanced (17,767 patients each). Patients receiving an SGLT2i vs those receiving a DPP4i had significantly lower numbers of hospitalizations per person per month (PPPM) and outpatient visits PPPM, and had shorter lengths of stay per hospitalization. Healthcare costs, including all-cause overall healthcare costs PPPM and all-cause hospitalization costs PPPM, were generally lower in patients receiving an SGLT2i than those receiving a DPP4i. Similar results were observed among patients with a higher BMI but not among patients with a lower BMI. SGLT2i were associated with lower HCRU and healthcare costs than DPP4i, suggesting economic benefits with SGLT2i vs DPP4i in type 2 diabetes mellitus management.

Real-world use of inotuzumab ozogamicin is associated with lower health care costs than blinatumomab in patients with acute lymphoblastic leukemia in the first relapsed/refractory setting.

Aim: To compare all-cause and acute lymphoblastic leukemia (ALL)-related healthcare resource utilization (HCRU) and costs among patients receiving inotuzumab ozogamicin (InO) and blinatumomab (Blina) for ALL in the first relapsed/refractory (R/R) setting. Patients & methods: We studied retrospective claims for adult commercial and Medicare Advantage enrollees with ALL receiving InO (n=29) or Blina (n=23) from 1January 2015 to 16February 2021. Mean per-patient-per-month (PPPM) HCRU and total costs were described and multivariable-adjusted PPPM total all-cause and ALL-related predicted costs were calculated. Results: Mean monthly ALL-related hospitalizations were the same for patients receiving InO and Blina (PPPM=0.8 stays); however, the length of ALL-related hospital stay was almost twice as long among patients receiving Blina versus InO (ALL-related: InO=7.6days; Blina=14.1days; p=0.346). In multivariable models, total ALL-related costs were 43% lower for InO compared with Blina (PPPM costs: InO=$93,767; Blina=$163,470; p=0.021). Conclusion: In the first R/R setting, patients who used InO had significantly lower all-cause and ALL-related costs compared with patients who used Blina, in part driven by hospitalization patterns.

Healthcare resource utilization, costs and treatment associated with myasthenia gravis exacerbations among patients with myasthenia gravis in the USA: a retrospective analysis of claims data.

Aim: There are limited data on the clinical and economic burden of exacerbations in patients with myasthenia gravis (MG). We assessed patient clinical characteristics, treatmentsand healthcare resource utilization (HCRU) associated with MG exacerbation. Patients & methods: This was a retrospective analysis of adult patients with MG identified by commercial, Medicareor Medicaid insurance claims from the IBM® MarketScan® database. Eligible patients had two or more MG diagnosis codes, without evidence of exacerbation or crisis in the baseline period (12months prior to index [first eligible MG diagnosis]). Clinical characteristics were evaluated at baseline and 12weeks before each exacerbation. Number of exacerbations, MG treatments and HCRU costs associated with exacerbation were described during a 2-year follow-up period. Results: Among 9352 prevalent MG patients, 34.4% (n=3218) experienced ≥1 exacerbation after index: commercial, 53.0% (n=1706); Medicare, 39.4% (n=1269); and Medicaid, 7.6% (n=243). During follow-up, the mean (standard deviation) number of exacerbations per commercial and Medicare patient was 3.7 (7.0) and 2.7 (4.1), respectively. At least two exacerbations were experienced by approximately half of commercial and Medicare patients with ≥1 exacerbation. Mean total MG-related healthcare costs per exacerbation ranged from $26,078 to $51,120, and from $19,903 to $49,967 for commercial and Medicare patients, respectively. AChEI use decreased in patients with multiple exacerbations, while intravenous immunoglobulin use increased with multiple exacerbations. Conclusion: Despite utilization of current treatments for MG, MG exacerbations are associated with a high clinical and economic burden in both commercial and Medicare patients. Additional treatment options and improved disease management may help to reduce exacerbations and disease burden.

Treatment Patterns, Healthcare Resource Utilization, and Direct Costs Among Patients Initiating Concomitant Use of a Calcitonin Gene-Related Peptide Monoclonal Antibody (CGRP mAb) and Novel Acute Medication in the United States.

To describe treatment patterns, all-cause and migraine-related healthcare resource utilization (HCRU), and direct costs among people with migraine treated with concomitant calcitonin gene-related peptide monoclonal antibody (CGRP mAb) and novel acute migraine medications (ubrogepant, rimegepant, lasmiditan) in the United States (US). This retrospective, observational cohort study utilized data from the IBM MarketScan® Research Databases and included adults initiating CGRP mAb or novel acute migraine medication as index medications between May 01, 2018, and Feb 28, 2021. All-cause and migraine-related HCRU (number of visits) and costs at baseline (12 months pre-index) and at follow-up (12 months post-index) were descriptively analyzed; differences between values at follow-up and baseline were reported. Of 4,167 included in the analysis (mean [SD] age: 43.7 [11.2] years), 89.2% were women, and 59.7% had chronic migraine. Adherence to the indexed CGRP mAb was 47% (using proportion of days covered [PDC]) and 80.1% (using medication possession ratio [MPR]); mean (SD) persistence was 273.4 (115.3) days). At follow-up, 43.9% of the patients discontinued their index preventive medication of which 80.2% switched to a different preventive migraine medication; 17.0% restarted their index preventive medication. Reductions in all-cause inpatient HCRU, all-cause inpatient and outpatient costs, and migraine-related outpatient HCRU were observed at follow-up vs. baseline, whereas increases in all-cause outpatient HCRU, all-cause medication costs, migraine-related inpatient HCRU, and migraine-related inpatient, outpatient, and medication costs were observed. In this study, observed treatment patterns with the indexed CGRP mAb were consistent with prior reports. Concomitant treatment with CGRP mAb and novel acute migraine medications led to reductions in some outcomes of HCRU and direct costs, however, increases were also observed. Treatment utilization, reductions in HCRU and cost savings identified in this study in favor of concomitant CGRP mAb and novel acute medications may help clinicians and other healthcare decision makers assessing appropriate therapeutic options for migraine management.
