RESUMEN
AIMS: Food allergies impose a large clinical and financial burden on patients and the health care system. However, little is known about the factors associated with health care resource use and costs. The aim of this study was to investigate health care resource use and costs in individuals with food allergies utilizing health care in the United States. METHODS: We conducted a retrospective analysis of insurance claims data from the Merative MarketScan Research Databases (indexed from 1 January 2015 to 30 June 2022). All-cause and food allergy-related health care resource use, direct medical, and out-of-pocket costs for medical services were estimated for 12 months post-index using International Classification of Diseases [ICD] codes. RESULTS: Of 355,520 individuals with food allergies continuously enrolled in a health insurance plan for ≥12 months pre- and post-index, 17% had a food allergy-related emergency department visit and 0.9% were hospitalized. The top patient characteristic associated with all-cause and food allergy-related hospitalizations, all-cause costs, and food allergy-related outpatient visit costs was a Charlson Comorbidity Index score of ≥2. Food allergy-related direct medical and out-of-pocket costs were high among patients with a food allergy-related visit. Out-of-pocket cost per patient per year for outpatient visits, emergency department visits, and hospitalizations had an estimated mean of $1631 for patients with food allergy-related visits, which is â¼11% of the total costs for these services ($14,395 per patient per year). LIMITATIONS: Study limitations are primarily related to the nature of claims databases, including generalizability and reliance on ICD codes. Nevertheless, MarketScan databases provide robust patient-level insights into health care resource use and costs from a large, commercially insured patient population. CONCLUSION: The health care resource use of patients with food allergies imposes a burden on both the health care system and on patients and their families, especially if patients had comorbidities.
Some people with food allergies might need extra visits to the doctor or hospital to manage allergic reactions to food, and these visits add to the cost of medical services for both families and for health care providers. Using records of health insurance claims, we looked into the factors affecting medical visits and costs in people with food allergies in the United States. For people with food allergies, having additional medical conditions (measured using the Charleson Comorbidity Index) were linked with extra medical visits and costs. Out-of-pocket costs were high for people who visited a doctor or hospital for their food allergies (costing each person more than $1,600 per year). The total medical cost of food allergy-related care was $14,395 per person per year, paid for by families and health care providers. Our findings might help to better manage and treat people with food allergies and reduce medical costs.

OBJECTIVE: Chronic spontaneous urticaria (CSU) is a debilitating inflammatory skin condition, often impacting quality of life. International guidelines recommend omalizumab, an anti-immunoglobulin E antibody, for second-line treatment. Our objective was to understand patient characteristics associated with prescription of omalizumab, and assess real-world outcomes in patients with CSU treated with omalizumab. METHODS: We analyzed data from the Adelphi Real World CSU Disease Specific Programme, a cross-sectional survey with retrospective data collection (December 2020-October 2021) from physicians and patients with CSU in the United States. RESULTS: Data from allergists (n = 45), dermatologists (n = 51), and primary care physicians (PCPs; n = 20) were included. At the time of data collection, one-third of patients were receiving omalizumab (n = 220) and 67% were eligible for but not receiving omalizumab (n = 455). Using logistic regression, the odds of receiving omalizumab were higher in patients whose entire bodies were affected by hives [odds ratio (OR) = 2.551; 95% confidence interval (CI) 1.502-4.333; p < 0.001] or with deteriorating/unstable prognoses at treatment initiation [OR = 2.219; 95% CI 1.031-4.777; p = 0.042], and lower in patients managed by PCPs [OR = 0.276; 95% CI 0.130-0.584; p < 0.001]. Estimates from an inverse probability weighted regression adjustment model indicated that patients receiving omalizumab had higher treatment satisfaction, improvements in itching, hives, angioedema, insomnia, and anxiety, and lower impact on work productivity, compared with patients not receiving omalizumab. CONCLUSION: Around two-thirds of patients with CSU considered eligible for omalizumab were not receiving the guideline-recommended therapy. Patients receiving omalizumab had better real-world outcomes compared with patients not receiving omalizumab. Ensuring patients receive the most appropriate treatment could benefit patients with CSU.
People with a skin rash known as chronic spontaneous urticaria (also called long-lasting hives) have itchy spots that last longer than 6 weeks. People with long-lasting hives may be treated with a medicine called omalizumab to help their itching. We asked doctors why they gave some people omalizumab. We found that only one out of every three people with long-lasting hives were given omalizumab. Doctors gave some people omalizumab because they had long-lasting hives on their whole body or their hives were getting worse. Other people received omalizumab because they were seeing a specialist doctor (allergist) instead of a primary care physician (also called a general practitioner). When compared with people who received other medicines, people being treated with omalizumab had reduced itching, less anxiety, and better well-being. These findings could help doctors choose the right medicine for people with long-lasting hives.
RESUMEN
Background: Food allergies impose a large psychosocial burden, including mental, emotional, and social aspects, on both patients and their caregivers. Patients, caregivers, and their families often experience anxiety, isolation, and fear around food allergies. Objective: To assess the real-world mental health burden of food allergies, using the Food Allergy Research & Education (FARE) Patient Registry (NCT04653324). Methods: Self-reported data from patients with food allergies, and their caregivers, were analyzed from the FARE Food Allergy History and Mental Health Concerns surveys. Odds ratios were also calculated as a measure of association between patient food allergy characteristics and the likelihood of having mental health concerns or a formal mental health diagnosis. Results: The FARE Patient Registry included 1680 patients/caregivers. Anxiety (54%) and panic (32%) were the most common emotions that patients reported as a result of eating the food that produced an allergic reaction. About two-thirds of patients reported mental health concerns related to food allergies (62%), including anxiety after an allergic reaction, anxiety about living with food allergies, and concerns about food avoidance. Caregivers also experienced fear for the safety of their children, and often sought mental health care to cope with worry related to caring for patients with food allergies. The likelihood of having food allergy-related mental health concerns was increased for patients experiencing more than 1 reaction per year (OR 1.68-1.90) and was lowered for patients having a formal mental health diagnosis (OR 0.43). Caregivers filling out the FARE survey for pediatric patients (OR 4.03) and experiencing food allergy-related mental health concerns (OR 2.36) were both significant predictors for having a formal mental health diagnosis. Conclusion: Our study highlights a continuing unmet need for mental health screening and support as part of the management of patients with food allergies.
RESUMEN
INTRODUCTION: Influenza is a common, seasonal infectious disease with broad medical, economic, and social consequences. Real-world evidence on the effect of influenza treatment on household transmission and healthcare resource utilization is limited in outpatient settings in the USA. This study examined the real-world effectiveness of baloxavir vs oseltamivir in reducing influenza household transmission and healthcare resource utilization. METHODS: This prospective electronic survey on patient-reported outcomes was conducted between October 2022 and May 2023 via CVS Pharmacy in the USA. Adult participants (≥ 18 years old) were eligible if they filled a prescription for baloxavir or oseltamivir at a CVS Pharmacy within 2 days of influenza symptom onset. Participant demographics, household transmission, and all-cause healthcare resource utilization were collected. Transmission and utilization outcomes were assessed using χ2 and Fisher exact tests. RESULTS: Of 87,871 unique patients contacted, 1346 (1.5%) consented. Of 374 eligible patients, 286 (90 baloxavir- and 196 oseltamivir-treated patients) completed the survey and were included in the analysis. Mean age of participants was 45.4 years, 65.6% were female, and 86.7% were White. Lower household transmission was observed with baloxavir compared with oseltamivir therapy (17.8% vs 26.5%; relative risk = 0.67; 95% CI 0.41-1.11). Healthcare resource utilization, particularly emergency department visits (0.0% vs 4.6%), was also numerically lower in the baloxavir-treated group; no hospitalizations were reported in either cohort. CONCLUSIONS: The findings from this real-world study suggest that antiviral treatment of influenza with baloxavir may decrease household transmission and reduce healthcare resource utilization compared with oseltamivir.
RESUMEN
Background: Food allergies are serious and potentially life-threatening, and often place a large burden on patients and their caregivers, including impacts on quality of life. Objective: To assess the real-world patient burden of food allergies, using self-reported data available from the Food Allergy Research & Education (FARE) Patient Registry (NCT04653324). Methods: The FARE Patient Registry is voluntary and captures real-world experiences of adults and pediatric patients in the United States, and their caregivers, through a series of surveys assessing patient health and experiences with food allergies. Self-reported data were descriptively analyzed. Results: The FARE study cohort included 5587 patients with food allergies; 82% had multiple food allergies and 62% were aged <18 years. About half of the patients were first diagnosed by an allergist/immunologist (53%), most commonly with a skin prick test (71%) or a serum immunoglobulin E test (62%). This analysis found that food allergies (most commonly peanut [66%], tree nuts [61%], egg [43%], and milk [37%]) impart a large clinical burden on patients, many of whom experience food-related allergic reactions and comorbidities. Many patients experienced >1 food-related allergic reaction per year (42%), with 46% experiencing food-induced anaphylaxis. Half of all food-related allergic reactions occurred at home. Accidental exposures to food allergens were experienced by 77% of patients. The most common allergic comorbidities reported by patients with food allergies were atopic dermatitis (48%), asthma (46%), and allergic rhinitis (39%). The clinical burden of food allergies were found to be greater in patients with multiple food allergies, and different for adults versus pediatric patients. Conclusion: This is the first study to assess patient experience and disease burden information from patients contributing to the FARE Patient Registry, thus providing a unique insight into the lives of patients in the United States with food allergies. These insights may assist clinicians and other public health stakeholders in the management of patients with food allergies.
RESUMEN
For patients with moderate-to-severe persistent allergic asthma, omalizumab is approved for subcutaneous administration according to a recommended dosing table based on weight and total immunoglobulin E (IgE) level. The aim of this analysis was to assess asthma outcomes including quality of life in patients with allergic asthma initiated on omalizumab in the PROSPERO trial; patients were stratified by where their IgE and body weight fell on the approved dosing table. Patient groups were defined as Inside Dosing Table: patients whose IgE and weight fell within the approved dosing table (n = 506); Insufficient Data to Recommend a Dose: patients who fell into the section of the approved dosing table where not enough clinical data were available to make dosing recommendations (n = 72); and Outside Dosing Table: patients who fell outside the approved dosing table due to baseline IgE and/or weight (n = 209). Overall, asthma and quality of life outcomes were improved after omalizumab initiation for both patients who fall within the recommended dosing table or those who fall outside the recommended dosing table. Our results suggest that omalizumab treatment may be effective in a wide range of patients with moderate-to-severe allergic asthma. ClinicalTrials.gov identifier NCT01922037.

INTRODUCTION: Antiviral therapy may be underutilized in patients at high risk for increased clinical and economic burden (e.g. older adults). We aimed to examine the benefits associated with antiviral treatment of seasonal influenza among treated and untreated Medicare beneficiaries. METHODS: This retrospective study of Medicare Claims Research Identifiable Files identified patients ≥66 years old with an influenza diagnosis in outpatient setting between October 2016-March 2019 (flu seasons 2016-2018). Index date defined as date of first claim with influenza diagnosis; baseline as the 12 months pre-index. Treated patients received antivirals ≤2 days from index. Untreated patients had no antivirals ≤6 months post-index. Treated/untreated patients were 1:1 propensity score matched. Outcomes (death, all-cause and respiratory-related healthcare resource utilization [HCRU] and costs) were assessed until death or up to 6 months post-index. Descriptive statistics were reported; Kaplan-Meier estimation was used for survival over time. RESULTS: Among 116,901 matched patient pairs, all-cause mortality within 6 months from index diagnosis was 1.6% among treated versus 4.3% among untreated patients. Rates (treated versus untreated) of all-cause inpatient hospitalizations during follow-up were 13.9% versus 22.7% and respiratory-related hospitalizations were 4.2% versus 9.0%. Mean (SD) total all-cause and respiratory-related costs were $9,830 ($18,616.0) and $900 ($4016.4) among the treated, respectively, versus $13,207 ($24,405.1) and $2,024 ($7,623.7) among untreated, respectively. All differences were statistically significant (p < 0.001). CONCLUSIONS: Lack of antiviral treatment is associated with increased mortality, HCRU, and economic burden in older Medicare beneficiaries with seasonal influenza. Future research should investigate whether the choice of antivirals affects influenza burden.
Previous studies have shown that antiviral drugs help prevent flu-related complications and lower healthcare utilization and costs. However, these previous studies have focused on working aged people with existing health problems. Our study looks at how antiviral treatment can lower the health and financial burden caused by the flu in older adults. Using a Medicare claims database from the 20162018 flu season, we identified 116,901 matched (treated versus untreated) patient pairs. All-cause mortality within 6 months from the index diagnosis (defined as the first claim with a flu diagnosis) was 1.6% among treated versus 4.3% among untreated patients. Rates (treated versus untreated) of all-cause inpatient hospitalizations during follow-up (defined as 6 months after the index diagnosis date) were 13.9% versus 22.7% and respiratory-related hospitalizations were 4.2% versus 9.0%. Mean total all-cause and respiratory-related costs were $9,830 and $900 among the treated, respectively, versus $13,207 and $2,024 among untreated, respectively. All differences were statistically significant (p < 0.001). This analysis of older adults with the flu found that prompt antiviral treatment is associated with lower rates of mortality and acute complications, reduced hospitalization, and lower healthcare costs. Use of antiviral treatment for patients at high risk of flu, such as older adults, is warranted.

BACKGROUND: Insurers manage the cost of specialty medicines via rebates, however it is unclear if the savings are passed on to patients, and whether reducing rebates may lead to changes in patient out-of-pocket (OOP) costs and medication adherence. This study examined two drug classes to understand the impact of reducing list prices to net prices, via lower-priced national drug codes (NDCs) or authorized generics, on patient OOP costs and adherence. METHODS: This retrospective analysis assessed IQVIA PharMetrics ® Plus adjudicated medical and pharmacy claims for commercially insured patients. Patient OOP costs per prescription and payer drug costs were assessed for evolocumab or alirocumab (proprotein convertase subtilisin/kexin type 9 inhibitors [PCSK9is]) or velpatasvir/sofosbuvir or ledipasvir/sofosbuvir (hepatitis C virus [HCV] medications). For PCSK9is and HCV medications, the original and lower-priced versions were compared. Adherence was estimated based on proportion of days covered (PDC) (PCSK9is) and receipt of full treatment regimen (HCV medications). RESULTS: In total, 10,640 patients were included (evolocumab, 5,042; alirocumab, 1,438; velpatasvir/sofosbuvir, 2,952; ledipasvir/sofosbuvir,1,208). After list price reductions, mean payer drug costs decreased by over 60%, while patient OOP cost reductions ranged from 14% to 55% (evolocumab: 55%, p < 0.01; alirocumab: 51%, p < 0.01; velpatasvir/sofosbuvir: 30%, p < 0.01; ledipasvir/sofosbuvir: 14%, p = 0.03). Patients with coinsurance as the largest contributor to their OOP costs had the largest reductions in OOP costs, ranging from adjusted, mean values of US$135 to US$379 (>60% reductions). Six-month PDC for PCSK9is and proportion receiving full HCV treatment regimen were high with the original versions and did not substantially differ with the new, lower-priced versions. CONCLUSIONS: Reducing list prices to approximate net prices (as a proxy for reducing rebates) resulted in lower patient OOP costs, particularly for those with coinsurance. Our findings suggest that future reduction of rebates may assist in patient affordability, although additional transparency is needed.

INTRODUCTION: Spinal muscular atrophy (SMA) is a genetic, neuromuscular disease caused by deletions and/or mutations in the survival of motor neuron 1 (SMN1) gene leading to reduced SMN protein levels. Nusinersen, an intrathecally administered antisense oligonucleotide therapy that increases SMN protein levels, is approved for use in adult and pediatric patients with SMA. Data to inform real-world patient adherence and persistence to nusinersen are limited, with disparities in the population with SMA, study design, and results. The objective of this study is to characterize real-world nusinersen adherence and persistence in patients with SMA. METHODS: This retrospective study examined nusinersen adherence and persistence over a 2-year period in patients with SMA in the USA from the IQVIA PharMetrics Plus claims database. Patients were followed from the date of first evidence of nusinersen treatment (occurring after 1 July 2017) until the end of the study period (31 December 2019) or end of continuous pharmacy and medical benefit enrollment, whichever came first. Subgroup analyses for nusinersen adherence and persistence were performed on the basis of age and presence or absence of spinal complications. RESULTS: The final cohort consisted of 179 patients with SMA treated with nusinersen. Adherence to nusinersen treatment was 41% at 56 weeks and 39% at 104 weeks. In the base-case persistence analysis, there was a decrease in persistence before 6 months (67%) and further decline at 1 (57%) and 2 years (55%). Patients with spinal complication versus without had numerically higher persistence with nusinersen. CONCLUSIONS: The findings suggest that adherence and persistence to nusinersen treatment appear low. Demographic (age ≥ 18 years) and clinical factors (no spinal complications) may contribute to nusinersen treatment discontinuation. Future research should explore possible reasons for low adherence and persistence to nusinersen treatment, such as clinical or logistical factors, patient preferences, and payer restrictions.
Spinal muscular atrophy (SMA) is a rare, genetic disease that causes patients to lose motor neurons over time. This makes tasks that involve movement control like walking and talking more difficult. SMA can be treated, but it is important that patients receive their scheduled doses of medicine as prescribed and stay on treatment. Nusinersen (SPINRAZA®) is a treatment for SMA that is given as an intrathecal injection into the cerebrospinal fluid of the spine. Patients receive six doses of nusinersen in the first year. After the first year, patients receive three doses every year for life.This study looked at whether patients received their scheduled doses, also called adherence, and how many patients remained on treatment, or persistence, over two years. This study involved 179 nusinersen-treated patients with SMA and used data from US health insurance plans. After 56 weeks of treatment, 41% of patients were adherent. After 104 weeks, 39% were adherent. After 6 months, 67% of patients were still on treatment. After 1 year, 57% were still on treatment. After 2 years, 55% of patients were still on treatment. The study showed that a low number of patients with SMA, particularly those older than 18 years with no spinal problems, remained on nusinersen for the intended time and received the treatment as prescribed. Future studies will look at possible reasons for low adherence and persistence to nusinersen, which may include difficulties traveling to a clinic or scheduling a visit, patient preference, or insurance restrictions.

BACKGROUND: Although asthma does not appear to be a risk factor for severe coronavirus disease 2019 (COVID-19), outcomes could vary for patients with different asthma subtypes. The objective of this analysis was to compare COVID-19 outcomes in real-world cohorts in the United States among patients with asthma, with or without evidence of allergy. METHODS: In a retrospective analysis of the COVID-19 Optum electronic health record dataset (February 20, 2020-January 28, 2021), patients diagnosed with COVID-19 with a history of moderate-to-severe asthma were divided into 2 cohorts: those with evidence of allergic asthma and those without (nonallergic asthma). After 1:1 propensity score matching, in which covariates were balanced and potential bias was removed, COVID-19 outcomes were compared between cohorts. RESULTS: From a COVID-19 population of 591,198 patients, 1595 patients with allergic asthma and 8204 patients with nonallergic asthma were identified. After propensity score matching (n = 1578 per cohort), risk of death from any cause after COVID-19 diagnosis was significantly lower for patients with allergic vs nonallergic asthma (hazard ratio, 0.48; 95% CI 0.28-0.83; P = 0.0087), and a smaller proportion of patients with allergic vs nonallergic asthma was hospitalized within - 7 to + 30 days of COVID-19 diagnosis (13.8% [n = 217] vs 18.3% [n = 289]; P = 0.0005). Among hospitalized patients, there were no significant differences between patients with allergic or nonallergic asthma in need for intensive care unit admission, respiratory support, or COVID-19 treatment. CONCLUSIONS: Asthma subtype may influence outcomes after COVID-19; patients with allergic asthma are at lower risk for hospitalization/death than those with nonallergic asthma.

OBJECTIVE: Patients with rheumatoid arthritis (RA) are vulnerable to severe complications of influenza. We assessed whether health care resource use (HRU) and costs differed between patients with RA and influenza who received antiviral medication compared with matched patients with RA and influenza not receiving antiviral therapy. METHODS: This was a retrospective US health insurance claims analysis over three influenza seasons (each October to April) in 2016-2019. Adults with RA and a subsequent diagnosis of influenza were included. Treated patients (receiving antiviral influenza treatment within 2 days of diagnosis) and untreated patients were propensity score matched using baseline covariates. HRU and costs were assessed for inpatient, emergency department (ED), and outpatient visits and compared between cohorts using χ2 tests and t tests. RESULTS: After matching, 2638 treated and 1319 untreated patients were included. For treated versus untreated patients, the mean number of all-cause outpatient visits was 0.96 versus 1.21 during 14 days of follow-up (P < 0.001) and 1.94 versus 2.24 over 28 days (P = 0.001), respectively. Over 28 days, the mean number of all-cause ED visits was lower among treated (0.23) than untreated (0.30) patients (P = 0.042). The mean number of respiratory-related outpatient visits was significantly lower for treated versus untreated patients, and mean costs for these visits were $17.89 versus $35.27 over 14 days (P < 0.001) and $28.92 versus $48.77 over 28 days (P < 0.001) for treated versus untreated patients, respectively. CONCLUSION: Our findings demonstrate that prompt antiviral treatment after influenza diagnosis may reduce HRU and costs in patients with RA.
RESUMEN
BACKGROUND: Amid continued uncertainty about the management of cancer patients during the pandemic, this study sought to obtain real-world data on the use of immune checkpoint inhibitors (ICIs) before COVID-19 diagnosis and its association with severity and survival outcomes in cancer patients who contracted COVID-19. METHODS: Cancer patients diagnosed with COVID-19 were identified from a large electronic health record database; those treated with ICIs before COVID-19+ diagnosis were matched in a 1:2 ratio to those not treated with ICIs, using a 2-step matching procedure. A descriptive analysis examined the difference in COVID-19 mortality (30-day and overall) and severity outcomes between the 2 cohorts, and overall survival was compared. RESULTS: Among 17 545 adults ≥18 years with cancer who tested positive for COVID-19 between February 20, 2020, and January 28, 2021, in the US, 228 ICI-treated patients were matched to 456 non-ICI-treated patients, comprising the 2 study cohorts. Clinical characteristics differed significantly between the 2 cohorts before matching, with metastatic disease, lung cancer, a history of smoking, and the presence of pulmonary comorbidities being more common in the ICI-treated cohort; after matching, the 2 cohorts were similar. There were no significant differences between the ICI-treated and non-ICI-treated cohorts for 30-day mortality (12.7% vs. 14.9%, P = .235), overall mortality (22.4% vs. 22.4%, P = 1.000), hospitalization (38.6% vs. 39.0%, P = .912), or emergency department visits (16.7% vs. 14.7%, P = .500). Overall survival was similar between the 2 cohorts. CONCLUSION: This analysis adds to the clinical evidence base that use of ICIs before SARS-CoV-2 infection does not affect COVID-19 severity or survival outcomes, supporting the continued use of ICIs in cancer patients during the pandemic.

BACKGROUND: In patients with metastatic melanoma, central nervous system (CNS) involvement is associated with poor prognosis, increased costs, and higher health care resource utilization (HCRU); however, previous cost-estimate studies were conducted before widespread use of targeted therapies and immunotherapies. OBJECTIVE: To estimate costs and HCRU in patients with metastatic melanoma with and without CNS metastases in the current treatment era following introduction of targeted therapies and immunotherapies. METHODS: This real-world retrospective cohort study used data from the IQVIA PharMetrics Plus claims database to estimate and compare costs and HCRU in patients with metastatic melanoma by presence or absence of CNS metastases between January 2011 and June 2019. Patients with at least 2 melanoma claims, at least 2 metastatic claims, and continuous enrollment at least 6 months before and at least 1 month after first metastatic diagnosis were included. Mean per-patient-per-month (PPPM) costs are reported in 2019 US dollars. Analyses were also conducted by time period of first metastatic diagnosis: 2011-2014 (reflecting BRAF inhibitor monotherapy and anti-CTLA-4 therapy) and 2015-2019 (reflecting availability of BRAF and MEK inhibitor combinations and anti-PD-1/PD-L1 therapies). RESULTS: Of 4,078 patients, 1,253 (30.7%) had CNS metastases. Patients with CNS metastases were more likely to receive any treatment (89.1% vs 58.9%; P < 0.001), including systemic treatment (73.3% vs 55.4%; P < 0.001) and radiation (65.8% vs 11.8%; P < 0.001), and to have brain imaging any time after metastatic diagnosis (98.3% vs 67.2%; P < 0.001). In patients with CNS metastases, 40.0% had dexamethasone 4 mg within 30 days of CNS metastatic diagnosis. Patients with CNS metastases incurred higher total mean PPPM costs ($29,953 vs $14,996; P < 0.001). The largest contributors were total radiology ($2,351 vs $1,110), targeted therapies ($2,499 vs $638), and immunotherapies ($7,398 vs $5,036). HCRU and costs were higher in patients with vs without CNS metastases regardless of time period of first metastatic diagnosis. In patients with CNS metastases, use of any systemic treatment was increased in 2015-2019 vs 2011-2014 (81.2% vs 64.5%; P < 0.001), including chemotherapy (68.1% vs 50.0%; P < 0.001), immunotherapy (60.9% vs 30.1%; P < 0.001), and/or targeted therapies (32.7% vs 27.4%; P = 0.05). Mean total PPPM costs for patients with CNS metastases increased from $28,183 in 2011-2014 to $31,569 in 2015-2019 (P < 0.001); main drivers were immunotherapies and targeted therapies. CONCLUSIONS: CNS metastases occur frequently in patients with metastatic melanoma and are associated with significantly increased economic burden compared with patients without CNS metastases; the largest contributors to total costs in the current treatment era are radiology, targeted therapies, and immunotherapies. Brain imaging remains underused, and there is an opportunity to improve outcomes through early detection of CNS metastases, potentially reducing the high HCRU and costs associated with CNS metastases.

PURPOSE: To date, there are no studies on healthcare resource utilization (HRU) and costs for treating periocular basal cell carcinoma (pBCC). We investigated real-world HRU and costs of patients with limited versus extensive pBCC. DESIGN: This was a retrospective cost analysis. METHODS: Administrative claims database was mined for basal cell carcinoma (BCC)-related claims from January 2011 to December 2018. Patients had ≥1 inpatient or ≥2 outpatient nondiagnostic claims for pBCC ≥30 days apart, ≥6 months of continuous enrollment in a health plan before the index date, and ≥18 months of continuous enrollment after the index date. Patients were categorized by disease severity (limited or extensive) using Current Procedural Terminology codes. A total of 1368 patients were propensity matched 1:1 for limited and extensive pBCC (n = 684 each). Outcomes were cost and HRU measures during the 18-month follow-up period. RESULTS: Patients with extensive disease had a higher number of outpatient visits (32.47 vs 28.81; P < .0001), radiation therapies (0.53 vs 0.17; P = .001), surgeries (1.82 vs 1.24; P < .001), days between first and last surgery (40.82 vs 16.51 days; P < .001), outpatient pBCC claims (3.89 vs 3.38; P < .001), and days between pBCC claims (170.43 vs 144.01 days; P < .001). Patients with extensive disease incurred higher total all-cause costs ($36,986.10 vs $31,893.13; P = .02), outpatient costs ($20,450.26 vs $16,885.87; P = .005), radiation therapy costs ($314.28 vs $89.81; P = .01), and surgery costs ($3,697.08 vs $2,585.80; P < .001) than patients with limited disease. CONCLUSIONS: Patients with extensive pBCC incurred higher costs, greater HRU, and longer time between first and last surgery versus patients with limited pBCC. Early diagnosis and early treatment of pBCC have economic benefits.

INTRODUCTION: Claims data (IBM MarketScan Commercial and MarketScan Medicare Supplemental databases) from June 30, 2011 to September 30, 2017 were used to evaluate the cost impact of human epidermal growth factor receptor 2 (HER2)-positive metastatic breast cancer (MBC) in this retrospective cohort study. METHODS: The primary analysis compared short-term costs for patients diagnosed with HER2+ MBC at least 180 days after the end of first HER2-targeted treatment (MBC+ cohort) versus a propensity score matched cohort of patients with breast cancer who did not develop MBC (MBC- cohort). A pseudo-post period for patients in the HER2+ MBC- cohort was defined by indexing to the HER2+ treatment completion-MBC diagnosis time interval of the matched pair in the HER2+ MBC+ cohort; we then compared average monthly cost differences between these groups for the year preceding and following MBC diagnosis. In secondary analyses, we estimated medium-term aggregate and categorical healthcare costs for patients with HER2+ MBC up to 3 years post-diagnosis. RESULTS: In the short-term primary analysis, costs for the HER2+ MBC+ and HER2+ MBC- cohorts were largely comparable in the year preceding MBC diagnosis. Monthly direct costs were significantly higher for the HER2+ MBC+ cohort in the months immediately preceding MBC diagnosis, with differences in the range of $500-5000. Following diagnosis, total monthly costs were $13,000-34,000 higher for patients in the HER2+ MBC+ cohort vs. the HER2+ MBC- cohort. In the medium-term secondary analysis, mean per patient total costs were $218,171 [standard error (SE) $5450] in the first year following MBC diagnosis and $412,903 (SE $13,034) cumulatively over 3 years following diagnosis (among patients with complete follow-up). Primary cost contributors were outpatient visits ($195,162; SE $8043) and HER2-targeted therapy drug costs ($177,489; SE $8120). CONCLUSIONS: HER2+ MBC is associated with high short-term and medium-term direct healthcare costs. These could be alleviated with early diagnosis and optimal standard-of-care treatment for early breast cancer, which can significantly reduce the risk of recurrence.

PURPOSE: Major depressive disorder (MDD) is a chronic mental disorder with a substantial clinical and economic burden. Despite the efficacy of adjunctive atypical antipsychotics (AAP) for augmentation in patients with major depressive disorder (MDD) who failed first-line antidepressant therapy (ADT), little is known of the impact of AAP choices on healthcare resource use and costs in real-world practice. Therefore, this study compared real-world healthcare utilization and costs in patients with MDD treated with brexpiprazole or extended-release (XR) quetiapine as adjunctive treatment to ADT. PATIENTS AND METHODS: Adults with MDD starting adjunctive treatment with brexpiprazole (n=844) or extended-release (XR) quetiapine (n=688) were identified in the adjudicated health plan claims data (07/2014 - 09/2016). Resource use and healthcare costs in the 6 months following treatment initiation were compared between non-matched populations, and between propensity score-matched groups, and by multivariable regression analyses. RESULTS: During follow-up, unadjusted all-cause hospitalization (6.6% vs 12.5%) and ED visits (17.0% vs 27.5%) were lower with brexpiprazole compared to quetiapine XR (both p<0.001). Brexpiprazole-treated patients had significantly lower mean medical costs (US$6,421 vs US$8,545, p=0.0123) but higher mean pharmacy costs (US$7,401 vs US$4,691, p<0.0001) than quetiapine XR-treated patients did. Total healthcare costs were not significantly different between the two cohorts. Propensity score-matched comparisons of 397 patients in each cohort showed no statistically significant difference in all-cause hospitalization, ED visits, and total healthcare costs; and significantly lower medical costs (US$5,719 vs US$8,602, p=0.0092) but higher pharmacy costs (US$7,091 vs US$5,091, p=0.0007) in brexpiprazole compared to quetiapine XR. In multivariable regressions, brexpiprazole was associated with 16.1% lower medical costs (p=0.0186) and 9.4% higher total healthcare costs (p=0.0463) as compared to quetiapine XR. CONCLUSION: Significantly lower medical costs were observed in patients with MDD treated with brexpiprazole vs quetiapine XR.
RESUMEN
OBJECTIVE: To estimate the treatment gap between a new epilepsy diagnosis and antiepileptic drug (AED) initiation in the United States. METHODS: Retrospective claims-based cohort study using Truven Health MarketScan databases (commercial and supplemental Medicare, calendar years 2010-2015; Medicaid, 2010-2014) and a validation study using PharMetrics Plus Database linked to LRx claims database (2009-2014). Persons met epilepsy diagnostic criteria, had an index date (first epilepsy diagnosis) with a preceding 2-year baseline (1 year for persons aged 1 to <2 years; none for persons <1 year), and continuous medical and pharmacy enrollment without epilepsy/seizure diagnosis or AED prescription during baseline. Outcomes included percentage of untreated persons (no AED prescription) up to 3 years' follow-up and comparative outcomes (incidence rate ratio: untreated persons/treated persons), including medical events and health care resource utilization. RESULTS: In the primary study, 59,970 persons met selection (or inclusion) criteria; 36.7% of persons with newly diagnosed epilepsy remained untreated up to 3 years after diagnosis. In the validation study (N = 30,890), 31.8% of persons remained untreated up to 3 years after diagnosis. Lack of AED treatment was associated with an adjusted incidence rate ratio (95% confidence interval) of 1.2 (1.2-1.3) for medical events, 2.3 (2.2-2.3) for hospitalizations, and 2.8 (2.7-2.9) for emergency department visits. CONCLUSIONS: One-third of newly diagnosed persons remain untreated up to 3 years after epilepsy diagnosis. The increased risk of medical events and health care utilization highlights the consequences of delayed treatment after epilepsy diagnosis, which might be preventable.

INTRODUCTION: The patient cost burden of oral anticancer medicines has been associated with prescription abandonment, delayed treatment initiation, and poorer health outcomes in the US. Since 2011, several small molecule tyrosine kinase inhibitors have been approved for the treatment of non-small cell lung cancer (NSCLC) patients with rearrangement of the anaplastic lymphoma kinase (ALK) gene. The objective of this study was to measure the impact of copay assistance on patient cost sharing and treatment patterns in patients prescribed oral ALK inhibitors (ALKi's). METHODS: Patterns of claims approval/rejection and payment/reversal, out-of-pocket (OOP) costs, and treatment persistence were reported for patients identified in the IQVIA Formulary Impact Analyzer database from January 2013 to August 2017 linked to a medical claims database. The primary study cohorts were patients with copay assistance, including manufacturer's copay cards, other discount cards, or free-trial vouchers, on the index ALKi claim, and patients without copay assistance at any time during the follow-up period. RESULTS: In total, 3,143 patients were included in analyses related to claim patterns, and 1,685 patients were included in analyses related to treatment persistence. Copay assistance decreased the OOP cost for the first approved ALKi by $1,930, on average. Patients with copay assistance picked up ALKi prescriptions from the pharmacy sooner than patients without copay assistance (2.6 days vs 25.7 days). In adjusted analyses, patients with copay assistance had 88.2% lower risk of abandoning their first approved prescription and 24.3% lower risk of discontinuing treatment with the first observed ALKi (all p < 0.001). CONCLUSION: Copay assistance reduced the patient cost burden for ALKi's and was associated with patients picking up their ALKi prescriptions, beginning ALKi treatment sooner, and remaining on treatment.

OBJECTIVE: Patient support programs, such as the ASSURE Program for long-acting injectable aripiprazole, are designed to help support access to medications, including long-acting injectable (LAI) antipsychotics for patients with schizophrenia. This study was conducted to evaluate adherence to long-acting injectable aripiprazole among patients utilizing the program local care centers (LCC). METHODS: Data collected from participating LCC between October 2014 and February 2018 were utilized. Characteristics of patients receiving injections at LCC and participating in additional support services of the program, types of program offering utilized and patient cost share for long-acting injectable aripiprazole were described. Adherence, measured as the proportion of days covered (PDC) during follow-up, was estimated in patients utilizing the LCC for 6 months and 9 months. Patients with PDC ≥80% were considered adherent to treatment. RESULTS: Two hundred and thirty-four patients received at least one injection at participating LCC and enrolled in the patient support program. Mean (SD) age was 37.3 (13.5) years; 60.7% were male; 32.5% were covered by Medicare. In total, 157 and 87 patients were actively utilizing the LCC for at least 6 months and 9 months, respectively. PDC of 97% and 98% were reported among patients with 6 months and 9 months of follow-up, respectively, and patients were considered adherent to long-acting injectable aripiprazole during follow-up. CONCLUSION: Patients utilizing the LCC demonstrated high medication adherence, suggesting that injection services provided by the centers may reduce barriers to treatment and help patients with schizophrenia remain on LAI antipsychotic treatment.

AIMS: The study compared all-cause and major depressive disorder (MDD)-related healthcare resource use (HRU) and costs in patients with MDD treated with atypical antipsychotic (AAP) adjunctive therapy early or later in treatment. MATERIALS AND METHODS: Adults with MDD and antidepressant treatment (ADT) who newly initiated adjunctive aripiprazole, brexpiprazole, lurasidone, or quetiapine between October 1, 2014 and September 30, 2015 were identified in the IQVIA Real-World Data Adjudicated Claims database; the index date was the date of the first AAP claim. Patients were stratified into three cohorts: AAP initiated in the first year (Y1); in the second year (Y2); and more than 2 years (Y3) of first ADT use. Within each cohort, HRU and costs were compared between the 12 months before and after the index date. Pre-post changes in HRU and costs were then compared between cohorts. RESULTS: Five hundred and six (36.7%) patients were categorized as Y1; 252 (18.3%) as Y2; and 622 (45.1%) as Y3. AAP use was associated with significantly decreased rates of all-cause and MDD-related hospitalization and emergency department visits, and increased rates of pharmacy fills and physician office visits; and the magnitude of changes was largest in cohort Y1. Cohort Y1 had the largest reductions in mean (±SD) all-cause medical costs per patient (-$10,496 ± $85,022, p = .015) compared to Y2 (-$2,474 ± $85,022, p = .572) and Y3 (-$472 ± $31,334, p = .823), mainly due to the reduction in hospitalization. After adjusting for differences in baseline characteristics, the largest reductions in hospitalization and medical costs were observed in cohort Y1. Similar increases in all-cause pharmacy costs were seen in all cohorts. A similar trend in costs was observed in MDD-related healthcare services. LIMITATIONS AND CONCLUSIONS: AAP treatment was associated with reductions in all-cause and MDD-related medical costs, primarily in decreased hospitalization. The reductions were largest among patients who initiated treatment in the first year.
