Healthcare Resource Utilization Among Patients With Agitation in Alzheimer Dementia

Background: Agitation in Alzheimer dementia is common, but the associated healthcare burden remains unclear. Objective: This retrospective analysis evaluated baseline characteristics, healthcare resource utilization, and costs among patients with agitation in Alzheimer dementia and those without agitation in Alzheimer dementia. Methods: Medicare beneficiaries from 100% of the Medicare Fee-for-Service claims database (2009-2016) with 2 or more claims 30 or more days apart for both Alzheimer’s disease and dementia and continuous enrollment with medical/pharmacy coverage for 6 months before and 12 months after the index diagnosis were included. Patients with agitation in Alzheimer dementia were identified by 2 or more claims 14 or more days apart using International Classification of Diseases-9-CM/-10-CM codes based on the provisional International Psychogeriatric Association agitation definition. Patients with severe psychiatric disorders were excluded. Two cohorts of patients (with and without agitation) were then defined, and patient characteristics, healthcare resource utilization, and costs were compared in a descriptive exploratory analysis. Results: Of 2 684 704 Fee-for-Service patients with Alzheimer dementia, 769 141 met all inclusion criteria; among these, 281 042 (36.5%) had agitation. The mean age in patients with and without agitation in Alzheimer dementia was 83 years. Most patients in both groups were female, but the proportion of males was slightly higher in the agitation in Alzheimer dementia group (30.3% vs 28.2%, respectively). Patients with agitation in Alzheimer dementia were more likely than those without agitation in Alzheimer dementia to have lower socioeconomic status (dual eligibility for Medicaid, 45.0% vs 41.7%, respectively) or be disabled (10.5% vs 9.4%). Overall, healthcare costs were higher in the agitation in Alzheimer dementia population compared with those without agitation in Alzheimer dementia (mean cost PPPY, $32 322 and $30 121, respectively), with the largest differences observed in inpatient and post-acute care costs. Conclusions: These exploratory findings underscore the substantial economic burden of agitation in Alzheimer dementia and highlight the need for treatment options for the agitation in Alzheimer dementia population to improve associated health outcomes.

Real-World Evaluation of Treatment Patterns, Healthcare Costs, and Healthcare Resource Utilization Among Patients with Non-small Cell Lung Cancer in the US Receiving Sotorasib.

Sotorasib was the first drug approved for adults with Kirsten rat sarcoma G12C-mutated locally advanced/metastatic non-small cell lung cancer (NSCLC) who received prior systemic therapy in the US. This study aimed to provide initial real-world evidence on patient characteristics, treatment patterns, healthcare resource utilization (HCRU), and healthcare costs (HCC) associated with sotorasib in US clinical practice. A retrospective observational study was conducted using the Optum Clinformatics® Data Mart US claims database spanning January 2016 to March 2023. The study population included adults with a diagnosis of lung cancer (diagnosis (Dx) date), claims for sotorasib on/post-Dx date (index date), Continuous enrollment for medical/pharmacy benefits from 180 days pre-Dx date to≥30 days post-index date was required. Patients receiving treatments for small-cell lung cancer (SCLC) pre-index were excluded. Outcomes were analyzed for patients receiving sotorasib as second or subsequent line (2L+) treatment and included adherence [proportion of days covered (PDC)], treatment duration, time to next treatment (TTNT), HCRU, and HCC during sotorasib treatment. Among 169 patients with lung cancer that met all inclusion criteria, 140 patients received sotorasib as 2L+ treatment (mean age: 71 years; 67.1% females). Mean PDC for sotorasib was 94.9%. Kaplan-Meier median treatment duration was 4.3 months. Median TTNT in patients with subsequent treatment (n=31) was 6.8 months. During sotorasib treatment, patients had a mean 3.87 outpatient, 0.09 inpatient, and 0.11 emergency visits per month. Mean monthly HCC during sotorasib treatment were US$23,063 versus $25,541 during the 180-day pre-index period. Patients in the US receiving sotorasib as 2L+ therapy for NSCLC in real-world clinical practice showed high adherence, TTNT comparable to progression-free survival observed in clinical trials, and HCC similar to those immediately prior to treatment demonstrating real-world benefits with no additional impact on healthcare resources with sotorasib.

Real-World Study of US Adults with Paroxysmal Nocturnal Hemoglobinuria Treated with Pegcetacoplan

Background: Paroxysmal nocturnal hemoglobinuria (PNH) is a rare, acquired, life-threatening disease characterized by complement-mediated hemolysis. OPERA is the first US longitudinal real-world study on C3 inhibitor therapy, known as pegcetacoplan. Methods: OPERA enrolled US patients with PNH, age ≥18, who were prescribed pegcetacoplan, and data were collected from routine care. Hemoglobin was reported by patients during regular follow-up (censored from transfusions). The Functional Assessment of Chronic Illness Therapy (FACIT)-Fatigue (0–52 score) and Patient-Reported Outcomes Measurement Information System scale for Cognitive Function Abilities (PROMIS-CF; 23.27–67.09 t-score) were completed electronically (low score = negative outcome). Patients self-reported incidence of healthcare resource utilization (HCRU). Results: By January 2024, 70 patients (mean age 44.6 years; 57.1% female) reported up to 9 months of pegcetacoplan treatment, with a median [IQR] follow-up of 6.6 [3.8] months. The latest reported hemoglobin levels improved by a mean (SD) of 2.6 (1.9) g/dL from baseline. At 3, 6 and 9 months, patients reported clinically meaningful improvements (≥5 points) in FACIT-F (53.3–69.0%) and (≥2 points) PROMIS-CF (46.7–55.2%). Patients reported a <10% incidence rate per person month of all HCRU events. Conclusions: This first longitudinal real-world US study indicates a positive trend in Hb, fatigue, and cognition with limited HCRU during pegcetacoplan treatment in adults with PNH.

Expert consensus on pharmacoeconomic evaluations alongside clinical trials (2024 edition)

As a technical tool to guide the optimal allocation of healthcare resources, pharmacoeconomic evaluation has been gradually applied to national healthcare decisions, including the adjustment of the National Reimbursement Drug List in China. With the acceleration of drug market approval and access to insurance coverage, the demand for pharmacoeconomic evaluation in healthcare decision-making is also increasing. Designing a pharmacoeconomic evaluation alongside clinical trials has become an important research direction and the source of evidence. In order to facilitate the standardization of this research field, the current consensus focuses on the topic of how to conduct a pharmacoeconomic evaluation alongside clinical trials from the Chinese healthcare system and decision-making context. The consensus group reconciled expert opinions and developed recommendations covering the entire process of study design, data collection and management, data analysis, and methods and results reporting. A total of 24 recommendations regarding to methodology and practice were developed from eighteen aspects including target population, selection of comparators, calculation of sample size, data collection of healthcare resource utilization, data collection of health-related quality of life, cost analysis, health outcome analysis, addressing the missing and censored data, etc., with the aim to provide reference for scholars and decision makers in this research filed.

Evaluating the Risk of Traumatic Brain Injury in Adults Following a Fall With Concomitant Use of Anti-Coagulation: A Retrospective Cohort Study.

Introduction Falls and fractures are major health challenges for older adults in England. Despite the advantages of anticoagulants, their use in the elderly is often restricted due to concerns about fall-related injuries. However, there is a lack of clear data on the risk of discontinuing anticoagulation therapy solely due to fall risk. NICE guidelines (2021) advise that anticoagulation should not be withheld solely based on age or fall risk. This study aims to assess the incidence of significant brain injuries or intracranial haemorrhages in patients on anticoagulant therapy, also comparing the independent risk factors for traumatic brain injury. Objective This study aims to assess the incidence of TBI following falls in patients on anticoagulant therapy, comparing outcomes between those using DOACs and Vitamin K antagonists. Methods A retrospective cohort study was conducted at Queen Alexandra Hospital, University Hospitals Portsmouth NHS Trust, from November 2023 to May 2024. Data were collected from 3,468 CT head scans performed on patients with a history of falls, including 801 on anticoagulation therapy. Results Of the 801 patients on anticoagulation, 763 (95.2%) were aged 65 or older, with a mean age of 83.1 years. Acute hemorrhage was detected in 3.1% (25/801) of patients. Patients on Warfarin and Dabigatran had significantly higher TBI risk compared to those on Apixaban (6.7%, p=0.02; and 7.6%, p=0.01, respectively), while Edoxaban and Rivaroxaban showed no significant difference. Also, older age (≥65 years) and higher frailty scores (CFS 6 and 7) were associated with increased TBI risk (p<0.05). All patients with acute hemorrhage received conservative management, and two patients experienced mortality within six months. Discussion The study indicates that the risk of TBI following falls in anticoagulated patients is 3.1% relatively low, aligning with existing literature. This underscores the need for careful consideration before discontinuing anticoagulation therapy solely based on fall risk. Hence, discontinuation of anticoagulation should be a patient-specific decision that carefully considers the balance between the risk of traumatic brain injury (TBI) and the benefits of anticoagulation therapy. Factors such as age, frailty, and the type of anticoagulant should all be taken into account. Clinical judgment and selective CT imaging can help balance patient safety with healthcare costs. Conclusion The incidence of adverse outcomes following head injury in patients on anticoagulant therapy is 3.1% and relatively low. Careful decision-making regarding the discontinuation of anticoagulation therapy, informed by patient background and presentation and selective CT imaging, is essential to manage risks effectively and optimize healthcare resource utilization.

Life After Invasive Meningococcal Disease: Insights from Survivors and Their Caregivers.

Invasive meningococcal disease (IMD) has a low incidence but is a life-threatening illness that is preventable via vaccination. Even with treatment, up to 10-15% of cases are fatal, and many survivors may experience severe long-term sequelae. Building upon the acute-phase findings presented in the Part1 manuscript for this study, we describe the long-term physical, social, psychological, and economic burden of IMD on US survivors and their caregivers in this Part2 manuscript. This was a novel, non-interventional, mixed-methods study among US survivors and their caregivers using a bespoke survey and qualitative interviews. Ten adult survivors, one adolescent survivor, and three caregivers participated in this study. Survivors described extensive physical, neurological, and systemic sequelae, including difficulty walking (11/11), repeat secondary infections (9/11), and numbness (6/11), among others, which were echoed by caregivers. Survivors shared that IMD had negatively impacted their long-term quality of life, citing long-term impacts including emotional impacts (11/11), social impacts (10/11), memory (7/11) and attention (5/11) problems, and difficulty with functional (10/11), self-care (7/11), and physical (6/11) activities. Caregivers were also impacted, describing emotional trauma (3/3), sleep problems (2/3), and day-to-day challenges (2/3). Long-term financial challenges related to healthcare resource utilization were substantial, with specialized care and rehabilitation therapy expenses (11/11), insurance challenges (8/11), and high out-of-pocket costs (6/11) for survivors. Productivity losses were also commonly described by survivors (9/11); sequelae hindered ability to attend school (9/11) or work full time (8/11). Caregivers (2/3) described taking leave from their employment, affecting family income. The humanistic burden of IMD on survivors and their caregivers is substantial and persistent. A comprehensive approach, including preventative measures (e.g., vaccination) and long-term medical, psychological, and financial support for those affected, is needed to mitigate the burden of IMD.

Healthcare resource utilisation and cost of care of systemic inflammation in individuals with atherosclerotic cardiovascular disease and chronic kidney disease

Abstract Background Atherosclerotic cardiovascular disease (ASCVD) is a chronic disease, progressed by localised or systemic inflammation (SI). Chronic kidney disease (CKD) facilitates the presence of SI and is associated with an increased risk of ASCVD. Previous studies have estimated that 1–2% of the population in Western countries suffer from both conditions. Purpose To investigates the healthcare costs and resource utilisation for individuals diagnosed with ASCVD and CKD, with or without SI. Method The study applied data from the Danish national health and administrative registries from 1994-2022. Patients with ASCVD were identified by ICD-10 codes. CKD was identified by eGFR [15-59mL/min/1.73m2], in the Register of Laboratory Results for Research (RLRR). The latter date of diagnosis of the two diseases were used as index date. CRP-test results were extracted from RLRR. Individuals with conditions associated with CRP-levels and tests observed in association with CVD events or antibiotic/antiviral drug use were excluded. Individuals with at least two valid CRP tests were included. If two CRP-test results ≥2mg/L to &amp;lt;20mg/L were observed less than six month apart, and within two years of index, the individuals were classified to have SI. Individuals diagnosed in the first year of available eGFR were excluded to ensure only incident individuals in the study. Outcomes included costs and use of inpatient (duration ≥12h) and outpatient (&amp;lt;12h) hospital care, cost of primary care and prescription drugs (adjusted to 2022 currency). Results were derived using linear regression models. Results A total of 19,162 individuals’ incident between 2012-2022 were identified – 68% had SI. SI individuals had higher healthcare costs from five years before to three years after index. Individuals generated a total healthcare cost of EUR 69,554 (SI) and EUR 39,540 (no SI) in the study period (difference EUR 30,014, p&amp;lt;0.001). In adjusted analysis, the attributable cost in the three years following index was 1.4 times higher for individuals with SI, compared to individuals with no SI (difference EUR 12,922, p&amp;lt;0.001). Inpatient care accounted for 85% of the cost. SI individuals had significantly more inpatient hospital contacts from four years before to five years after index (7 attributable contacts total, 4.7 attributable contacts after index, 1.2 times more, p&amp;lt;0.001), and more outpatient contacts from five years before to three years after index (6.2 attributable contacts total, 2.3 attributable contacts after index, 1.3 times more, p&amp;lt;0.001). The largest difference was found in the year following index, where the difference was EUR 7,666 (1.5 times higher, p&amp;lt;0.001) cost, 1.5 (1.3 times higher, p&amp;lt;0.001) inpatient hospital contacts, and 1.1 (1.3 times higher, p&amp;lt;0.001) outpatient hospital contacts (adjusted estimates). Conclusion Individuals with SI represent a significant burden to the healthcare system, both in terms of healthcare cost and healthcare resource utilisation.Total healthcare costsAttributable hospital contacts

Health care utilisation in patients with mild pulmonary hypertension - EVIDENCE-PAH UK study

Abstract Background ESC/ERS 2022 guidelines1, redefined precapillary pulmonary hypertension (PH) as patients with a mPAP&amp;gt;20mmHg,PVR&amp;gt;2WU and PAWP&amp;lt;15mmHg1.We and others identified patients with mildly elevated pulmonary artery(PA) pressures demonstrates a higher mortality2-4. It is important to understand healthcare resource utilisation(HRCU) in this newly defined group who now meet the thresholds for diagnosis, however, treatment options are limited. Purpose The EVIDENCE-PAH aims to describe mortality and hospitalisation outcomes, baseline demographics in mild elevations in PA pressure in a national cohort. We report preliminary analysis of HRCU from data obtained from NHS Hospital Episode Statistics(HES); inpatient admissions, outpatient(OP) and emergency attendances(AE). Method Retrospective analysis of all patients with a mPAP&amp;lt;25mmHg and a sample of patients with a mPAP≥25mmHg at index-right heart catheterisation(RHC), across all UK PH tertiary centres between 2009-2017 with hospitalisation data captured 24-months pre and post index-RHC. For analysis patients were categorised into 3 groups; normal haemodynamics(mPAP&amp;lt;21mmHg &amp; PVR≤2WU), mild elevation in haemodynamics(mPAP&amp;lt;21mmHg &amp; PVR&amp;gt;2WU, mPAP21-24mmHg with all PVR groups, mPAP&amp;gt;25mmHg &amp; PVR≤3WU) and abnormal haemodynamics(mPAP&amp;gt;25mmHg &amp; PVR&amp;gt;3WU). Results A total of 2413(82.3%) patients had complete records 24-months pre and post index-RHC; 561(23.2%), 1228(50.9%) and 624(25.9%) in the normal haemodynamic, mildly elevated haemodynamic and abnormal haemodynamic groups respectively. Figure 1, demonstrates HRCU; Unscheduled admissions are significantly higher in the abnormal haemodynamic group 24-months pre index-RHC compared to the normal/mild elevations in haemodynamic groups (p-value&amp;lt;0.05). There was reduction in unscheduled encounters 24-months post index-RHC in the normal/abnormal haemodynamic group. No significant difference identified in AE attendance and OP 24-months post across all haemodynamic groups. Total HRCU demonstrates a lower attendance 24-months post RHC in normal versus abnormal haemodynamic group (p-value&amp;lt;0.05). Multivariate analysis demonstrates unscheduled admissions 24-months pre/post index RHC, as an independent predictor of survival, adjusted for age, sex and haemodynamics (Figure 2;p-value&amp;lt;0.05). Conclusion Unscheduled admissions may act as a discriminator identifying advanced PH (abnormal haemodynamics), but not normal versus mild elevations in haemodynamics. Meanwhile AE and OP attendances fails to discriminate between normal and mild elevation in haemodynamics. Unscheduled admissions 24-months pre/post index RHC is an independent predictor of survival which may lend as a useful surrogate marker for mortality in the PH population as a whole. Although total HRCU appears high across haemodynamics groups referred to PH centre, in the 24-months post RHC HRCU increases in the mild/abnormal haemodynamic groups, this may represent ongoing unmet need in this group.

Sex-specific clinical outcomes and healthcare resource utilization in the 5 years following hospitalization for heart failure

Abstract Background Heart failure (HF) a leading cause of hospitalization, and sex differences in care have been described. Purpose We assessed sex-specific clinical outcomes and healthcare resource utilization following hospitalization for HF. Methods This was an exploratory analysis of patients hospitalized for HF across 10 Canadian hospitals enrolled in the Patient-Centred Care Transitions in HF pragmatic cluster-randomized trial. Primary outcome was all-cause mortality. Secondary outcomes included all-cause readmissions, HF readmissions, emergency department (ED) visits, and healthcare resource utilization. Outcomes were obtained via linkages with administrative datasets. Results The 4441 patients (50.7% female) had high event rates. At 5 years of follow-up, 63.6% male and 65.5% of male and female patients, respectively, had died (p=0.19); 85.4% and 84.4% of male and female patients, respectively, were readmitted with no sex differences in mean [SD] all-cause readmissions (males, 2.8 [7.8] and females, 3.0 [8.4], p=0.54) or HF readmissions (males, 0.9 [3.6] and females, 0.9 [4.5], p=0.80) per person. The mean (SD) annual total healthcare costs per patient was $80334 (116762) for males and $81010 (112625) for females, with no sex difference (p=0.90); however, there were sex differences in cost breakdown: males incurred greater costs from specialist, hemodialysis, and day surgical care, and females incurred greater costs from home visits and long-term care. Conclusions Males and females were at similarly high risk of mortality and readmissions, and had similar total healthcare costs following hospitalized for HF. Notwithstanding similar risks, males received relatively more specialist and invasive care, and females received relatively more supportive care.

Characterizing disease burden and health care resource utilization in patients with hypertrophic cardiomyopathy: a nationwide real-world study in Finland

Abstract Background Hypertrophic cardiomyopathy (HCM) is an often hereditary myocardial disease with an estimated prevalence of 1:500 in the general population. Purpose This study aimed to investigate healthcare resource utilization (HCRU) and associated costs in patients diagnosed with HCM (and the associated subtypes: obstructive or non-obstructive) in a nationwide cohort in Finland. Methods This retrospective, registry-based cohort study included all Finnish patients diagnosed with HCM between 2000 and 2021, who were 12+ years old at the time of diagnosis, as identified from the national care registers for healthcare. HCRU data were collected between 2014 and 2021 from the Finnish national care registers for health care and the social insurance institution. Data pertaining to New York Heart Association (NYHA) classification were collected from three Finnish university hospitals. Results The study cohort comprised 5,834 patients with an HCM diagnosis; obstructive HCM accounted for 34% of cases. Mean per patient-year costs were €6638, 95% confidence interval (CI) €6472-€7415, and €6112, 95% CI €5957-€6560 for those with obstructive and non-obstructive HCM respectively. All-cause hospitalizations at specialized care were the most prominent cost associated with patients with obstructive and non-obstructive HCM equating to 46.3% and 46.1% of the total cost respectively (Fig 1.). Comorbidity burden, as measured by Charlson comorbidity index (CCI) score, was greater in patients with the obstructive than non-obstructive phenotype of the disease (CCI ≥4: 2.2 and 1.8, p&amp;lt;0.01, respectively). The highest utilization of invasive procedures was found for patients with NYHA class III-IV. Conclusion This population-based study, utilizing real-world data, provides novel insights into HCRU and related costs among Finnish patients with HCM (and associated subtypes). HCRU appears to be primarily driven by hospitalizations at specialized care. Furthermore, the data indicate that patients with obstructive HCM are likely to have a more severe disease, with higher comorbidity burden and requiring more invasive procedures than patients with the non-obstructive form of the disease. However, there were no statistically significant differences in health care costs between those with obstructive and non-obstructive HCM.

Cost-effectiveness of respiratory syncytial virus adjuvanted vaccine in Portuguese aged ≥ 60 years

Abstract Background Respiratory syncytial virus (RSV) infections are one of the leading causes of lower respiratory tract disease among adults aged ≥60 years in Europe. This study aims to assess the potential public health impact of the RSVPreF3 OA adjuvanted vaccine, the first approved preventive intervention for the older adult population in Portugal. Methods A monthly-cycle static Markov model was developed to assess RSVPreF3 OA adjuvanted vaccine impact on adults aged 60 years and older in Portugal. A single dose of RSVPreF3 OA adjuvanted vaccine was compared to no-vaccination over a three-year time-horizon. The model captures lower respiratory tract disease (LRTD) RSV cases, hospitalizations, deaths, and healthcare resource utilization. Data inputs were based on local published literature, supplemented by the best available data when local information was lacking. Results Based on preliminary analysis considering 75% vaccine coverage, model outputs estimate that RSVPreF3 OA adjuvanted vaccine can prevent 71,433 LRTD cases requiring medical attendance, 11,067 hospitalizations, 1,793 intensive care unit admissions and 1,003 deaths. The model estimates that 32 adults need to be vaccinated to avoid one RSV LRTD case, 207 adults need to be vaccinated to avoid one hospitalization and 2,283 adults need to be vaccinated to avoid one death. The incremental cost-effectiveness ratio was estimated at 9,541€, hence the RSVPreF3 OA adjuvanted vaccine is cost-effective compared to no vaccination. Conclusions The results demonstrate a strong preventive impact of the RSVPreF3 OA adjuvanted vaccine on health outcomes and healthcare resource utilization in adults ≥60 years, leading to a significant public health benefit. This result emphasizes the importance of preventing RSV to preserve the health and well-being of Portugal’s older adults. In addition, data from ongoing studies may enhance precision and extensive sensitivity analyses validate the robustness of the model’s input assumptions. Key messages • This study shows the robust evidence of RSVPreF3 OA adjuvanted vaccine to improve public health by preventing thousands of hospitalizations and deaths among ≥60 years, in Portugal. • Vaccinating adults aged ≥ 60 years with RSVPreF3 OA adjuvanted vaccine in Portugal is a cost-effective strategy.

Burden of systemic inflammation and associated health outcomes in adults with atherosclerotic cardiovascular disease managed in routine care

Abstract Background The burden and outcomes of inflammation in people with atherosclerotic cardiovascular disease (ASCVD) are poorly defined, particularly beyond the controlled settings of trials and research cohorts. Methods We conducted a longitudinal observational study of adults with ASCVD undergoing C-reactive-protein (CRP) testing in routine healthcare in Stockholm, Sweden. After excluding CRP tests associated with acute illness and patients with medications/conditions that bias CRP interpretation, the systemic inflammation of participants was defined over a 3-month ascertainment window. Baseline determinants of CRP≥2 mg/L were explored with logistic regression, and baseline CRP categories were compared via Poisson and Cox regression for subsequent healthcare resource utilization and occurrence of major adverse cardiovascular events (MACE), heart failure hospitalization, and all-cause death. Result After applying inclusion/exclusion criteria, we identified 84,399 adults with ASCVD with a mean age of 71 years and of which 54% were men. In total, 60% had CRP≥2 mg/L. At baseline, female sex, older age, lower kidney function, albuminuria, diabetes, hypertension, and recent anemia, were associated with CRP≥2 mg/L. Conversely, the use of RASi, antiplatelets, and lipid-lowering therapy were associated with lower odds. Over a median follow-up of 6.4 years and compared to people with CRP &amp;lt;2 mg/L, those with CRP≥2 mg/L had a higher rate of hospitalizations, days spent in hospital, outpatient consultations, and dispensed medications during follow-up (P&amp;lt;0.05 for all). They also had a higher rate of MACE [adjusted hazard ratio (HR), 1.30; 95% CI, 1.27–1.33], heart failure hospitalization [1.24; 1.20–1.39], and all-cause death [1.35; 1.20–1.30]. Results were consistent across subgroups and more granular CRP categories, and robust to the exclusion of extreme CRP values or early events. Conclusions Two in three adults with ASCVD have systemic inflammation. A CRP≥2 mg/L is associated with excess healthcare resource utilization as well as increased rates of MACE, heart failure, and death.

Mortality, Clinical Complications, and Healthcare Resource Utilization Associated with Managing Transfusion-Dependent β-Thalassemia and Sickle Cell Disease with Recurrent Vaso-occlusive Crises in Italy.

To examine the clinical burden and healthcare resource utilization (HCRU) among patients with transfusion-dependent β-thalassemia (TDT) and patients with sickle cell disease (SCD) with recurrent vaso-occlusive crises (VOCs) in Italy. Eligible patients were identified from an administrative claims database from 1 January 2010 and 1 February 2019. Patients with TDT had ≥ 1 iron chelation treatment, ≥ 8 red blood cell transfusions (RBCTs) during any 12-month period, and ≥ 12 months of available data pre- and post-index (i.e., first RBCT claim). Patients with SCD with recurrent VOCs had ≥ 2 VOCs/year in ≥ 2 consecutive years and ≥ 12 months of available data pre- and post-index (second VOC claim in the second of 2 consecutive years). Patients were propensity score matched to five controls by age, sex, geographic area, and index year. Clinical and HCRU outcomes were evaluated post-index. In total, 214 patients with TDT and 111 patients with SCD with recurrent VOCs were matched to 1070 and 555 controls, respectively. Both patient groups had substantially higher mortality rates than controls (TDT: 4.8 versus 0.8 deaths per 100 person-years; SCD: 1.6 versus 0.4 deaths per 100 person-years). Clinical complications were prevalent in both patient groups. Compared with controls, both patient groups had significantly higher mean rates of all-cause hospitalizations (TDT: 1.4 versus 0.1; SCD: 2.0 versus 0.1) and outpatient services (TDT: 21.9 versus 1.6; SCD: 6.2 versus 1.0) per patient per year (all: p < 0.05). Management of TDT and SCD in Italy is associated with significant clinical and health system burden, highlighting the need for new treatments that eliminate RBCTs and VOCs.

Costs of Potential Medication Wastage Due to Switching Treatment Among People With Multiple Sclerosis.

Background: Unused medications negatively impact healthcare resource utilization and environmental safety, contribute substantially to annual healthcare expenditures, and may ultimately affect patient health outcomes. People with multiple sclerosis (PwMS) commonly switch disease-modifying therapies (DMTs), leading to medication wastage and substantial costs for insurers and patients. Objectives: To estimate the cost associated with potential medication wastage (PMW) in a subcohort of PwMS receiving oral or self-injectable US Food and Drug Administration-approved DMTs who switched DMTs in a calendar year in the United States. Methods: This retrospective cohort study included adults with MS and used PharMetrics® Plus claims data from 2017 to 2021. PwMS were required to have 12 months of continuous eligibility for the entire year and a claim for at least 2 unique DMTs during the same calendar year. The PMW cohort was defined as those who had an aggregate overlap in days' supply across DMT switches within the year; those in the non-PMW cohort did not. The cost of PMW for insurers and PwMS due to overlap was calculated only at the point of switch to the new DMT and defined as the cost of the remaining days' supply of the prior DMT. Results: The number of PwMS meeting the inclusion criteria was 1762 in 2017, 1947 in 2018, 1679 in 2019, 1461 in 2020, and 1782 in 2021. Approximately 95% of PwMS switched DMTs once within single calendar years, and 25% (n = 381-464) contributed to PMW. For those who had overlapping DMT supply, it was estimated that 34% to 38% of the DMT being switched from was potentially wasted. The total cost of PMW paid by the insurer and PwMS ranged from 1 489 859. While most of the total cost ( 1 450 328) was paid by the insurer, PwMS still owed substantial amounts ( 74 578). Across all PwMS, the per person per year cost ranged from 846. The estimated wastage and associated costs were consistent across all study years. Conclusions: DMT switching is common among PwMS, resulting in PMW and high costs to patients and insurers.

Approximately 95% of PwMS switched DMTs once within single calendar years, and 25% (n = 381-464) contributed to PMW. For those who had overlapping DMT supply, it was estimated that 34% to 38% of the DMT being switched from was potentially wasted. The total cost of PMW paid by the insurer and PwMS ranged from $1 200 866 to $1 489 859. While most of the total cost ($1 172 140-$1 450 328) was paid by the insurer, PwMS still owed substantial amounts ($28 726-$74 578). Across all PwMS, the per person per year cost ranged from $716 to $846. The estimated wastage and associated costs were consistent across all study years. Conclusions: DMT switching is common among PwMS, resulting in PMW and high costs to patients and insurers.

Quality of life measures with etripamil self-administration for acute episodes of paroxysmal supraventricular tachycardia in a medically unsupervised setting: patient-reported outcomes from NODE-303

Abstract Background Etripamil nasal spray (NS) is a fast-acting, self-administered calcium-channel blocker in development for the conversion of AV-nodal dependent paroxysmal supraventricular tachycardia (PSVT) in a medically unsupervised setting. Prior studies show favorable safety and efficacy in converting single episodes of PSVT to sinus rhythm (SR). Purpose In NODE-303, patient-reported outcome (PRO) instruments assessed quality of life (QoL) over multiple etripamil-treated episodes of PSVT. Methods NODE-303 was an event-driven, multi-center, open-label Phase 3 study in North and South American patients with documented PSVT that evaluated the safety and efficacy of etripamil in PSVT termination, over multiple episodes and without the need for prior test dosing. Enrolled patients who perceived PSVT symptoms applied an ambulatory ECG cardiac monitoring system (CMS), performed a pre-trained vagal maneuver and, if symptoms persisted, self-administered etripamil NS 70 mg. A study amendment allowed a repeat dose (etripamil NS, 70 mg) if symptoms persisted 10 min after the first dose. Each patient could self-treat up to 4 episodes. Safety was assessed through adverse events, clinical data, and ECG CMS recordings. The Treatment Satisfaction Questionnaire for Medication (TSQM; validated for acute episodic assessments) and other PROs were administered, and healthcare utilization data were acquired. Patients completed PROs at baseline (BL), monthly, and per PSVT episode, which collected information on symptoms, episode characteristics, rescue medications, and emergency room visits. Additional PROs were the Brief Illness Perception Questionnaire (BIPQ), Cardiac Anxiety Questionnaire (CAQ), and 36-Item Short Form Health Survey (SF-36). Results There were higher proportions of patients reporting mild, minimal or no disease severity, every 6 months, than at BL; extremely severe, severe, and moderate disease severity was reported by smaller proportions of patients than at BL, though incomplete surveys at later visits may limit this analysis. Anxiety and stress about future PSVT episodes were consistently reduced from BL. Measures of treatment satisfaction, effectiveness, and convenience were consistent across multiple episodes, and were at levels considered favorable for the TSQM instrument (Table 1). Rates of emergency-room visits and hospital admissions across multiple, treated PSVT episodes were similar to those observed in trials assessing single episodes (Table 2). The BIPQ, CAQ or SF-36 had no notable changes from BL. Conclusions Etripamil self-administration was associated with patient-reported improvements in degree of disease severity, decreased anxiety and stress over future PSVT episodes, and levels of treatment satisfaction, effectiveness, and convenience considered favorable for respective PRO instrument. Using a symptom-prompted, self-administered treatment for PSVT could potentially improve QoL measures and reduce healthcare resource utilization.

Burden of vaso-occlusive crisis, its management and impact on quality of life of Indian sickle cell disease patients.

Sickle cell disease (SCD) with vaso-occlusive pain crisis (VOC) significantly impacts patient well-being and often results in extensive healthcare resource utilization. This study assessed the VOC burden, its management and its impact on patients' quality of life (QoL). A cross-sectional observational study was conducted between November 2021 and June 2022, including 1000 SCD patients from high-prevalence states in India. Data on demographics, clinical characteristics, VOC severity, management and QoL were collected. The study revealed that 33.5% of patients reported at least one VOC episode during the study period. In the year prior to their enrolment, 836 (83.60%) patients reported at least one VOC episode, with an equal proportion of 407/487 (83.6%) adults and 429/513 (83.6%) paediatric patients, reducing their QoL across all domains compared to patients without VOC. Of these, 469/1000 patients (46.9%) experienced ≥3 VOC episodes. Additionally, 764/1000 (76.40%) patients managed their VOCs at healthcare facilities, with 501/1000 (50.1%) requiring inpatient admissions. Further, 71.80% of patients received Hydroxyurea (HU) therapy. The study depicts the severity of the Arab-Indian haplotype in Indian SCD patients visiting healthcare settings based on high VOC burden. This highlights the urgent need for better management strategies and resource allocation for these patients.

Economic Burden of Treatment-Resistant Depression: Insights from Real-World Data

Background: Treatment-resistant depression (TRD) is a highly prevalent condition. It is generally referred to as the failure of at least two or more prior treatments with antidepressants or augmentation therapy with adequate dose and duration. TRD affects the individual's overall health and social life, in addition to the economic impact associated with the illness. Therefore, this review is focused on examining the financial burden of illness among patients with TRD across different countries and identifying the key drivers for the incremental costs and healthcare resource utilization (HRU). Methods: A literature search was carried out in the PubMed database using relevant MeSH terms. This review included relevant studies published between 2019 &amp; 2024. Results: Overall, 22 studies were included in this review, with the majority based in the United States (n=15). The majority of the patients were females, ranging from 53.1% to 77%, and the mean age of patients with TRD ranged from 37.7±14.4 to 73.1±6.5 years. The mean annual all-cause healthcare cost per patient ranged from $3,190 to $40,040. The mean annual all-cause indirect costs per patient ranged from $4,199 to $6,342. Outpatient visits were the frequently utilized healthcare services, especially psychiatric visits and visits to general practitioners or family physicians. The incremental costs were primarily driven by worsening symptom severity, the presence of comorbidities, advancing age, and frequent visits to specialists. Conclusion: Regardless of the factors influencing the cost burden, TRD generally accounts for higher healthcare use and costs compared to individuals with major depressive disorder or without any mental illness. This underscores the need for fostering newer interventions and implementation of multidisciplinary approaches to lessen the cost burden of this condition, in addition to managing it effectively.

A smartphone app for preschool wheezing and reliability of medical history collection

BackgroundThe use of mobile applications helps improving self-management in adolescents with asthma. However, no evidence is available for children with preschool wheezing. In addition, we have no data on the reliability of medical history collected at visits. The first aim was to assess the feasibility of a smartphone app in the management of preschool wheezing; secondly we aimed to evaluate the reliability of anamnestic data collected during face-to-face medical interviews.MethodsChildren with recurrent wheezing, age between 25 and 72 months, were randomly assigned to the intervention group, provided with a smartphone app for symptoms monitoring and asthma attack treatment, or to the control group, with a written action plan. At follow-up medical history was collected and the asthma control test and a clinical questionnaire were completed. App acceptability was also explored. Respiratory symptoms, medication and utilization of healthcare resources were collected. Plus, medical information obtained from the paper questionnaires was compared with data daily recorded by the app.ResultsWe enrolled 85 preschool children with recurrent wheezing: 43 assigned to the intervention and 42 to the control group. The average (SD) adherence to e-Diary compilation was 60 (15)%. The acceptance and usability of the intervention was favorable as 70% and 93% of participants in the intervention arm described the app as ‘’simple and intuitive’’ at Visit1 (after 3 months from enrollement) and Visit2 (3 months later than Visit1), respectively and 95% and 98% found it useful in symptoms management. There were no significant differences between the two groups in clinical outcomes. At Visit1, the cACT median score (IQR) was 23,5 (21–25) for the control group (42 patients) and 23 (21–24) for the intervention group (43 patients). At Visit2 (41 controls and 42 in the intervention group) it was 25 (24–25) and 24 (24–25), respectively. Secondary analysis of data from the intervention group showed higher incidence of daily symptoms recorded by the app in comparison with the paper questionnaire, suggesting that collection of retrospective medical history may not be completely reliable.ConclusionsThe smartphone app is usable and acceptable by families of preschool wheezers. Future controlled trial are needed to prove an impact on clinical outcomes or its efficacy in a telemedicine program. Finally a daily questionnaire could provide physicians with a more reliable clinical picture as reflected better daily asthma symptoms than the written retrospective questionnaire filled at clinical visit.

Impact of Malnutrition on the Length of Stay for Hospitalized Chimeric Antigen Receptor T-cell (CAR-T) Therapy Patients in the United States (2020).

Background Chimeric antigen receptor T-cell (CAR-T) therapy offers a promising treatment for certain malignancies but can be associated with complications. Malnutrition and cachexia are common in cancer patients and may worsen outcomes. This study investigated the impact of malnutrition on the length of hospital stay (LOS) in patients with hematologic malignancies undergoing CAR-T therapy. The analysis focused on different subpopulations, including those with acute lymphoblastic leukemia (ALL), multiple myeloma (MM), diffuse large B-cell lymphoma (DLBCL), and non-Hodgkin lymphoma (NHL) excluding DLBCL. Methods Utilizing the 2020 National Inpatient Sample (NIS) data, we performed survey-based mean estimation analyses for LOS across various subpopulations of CAR-T therapy patients. These subpopulations were defined by specific diagnoses: ALL, myeloma, DLBCL, and NHL excluding DLBCL. We compared the LOS between patients with and without malnutrition using STATA accounting for the complex survey design. Cachexia was included as disease-induced malnutrition. Results The total CAR-T population used for analyses included 439 patients, and malnutrition was present in 50 (11.39%). The overall CAR-T population demonstrated a significantly longer LOS for patients with malnutrition (30.92 days, 95% CI: 24.30 to 37.54) compared to those without malnutrition (17.97 days, 95% CI: 15.48 to 20.46, p = 0.0002). This trend held true across subgroups. Specifically, the ALL population had a significantly longer LOS with malnutrition (45.25 days, 95% CI: 35.46 to 55.04) compared to non-malnourished patients (27.58 days, 95% CI: 16.74 to 38.42, p = 0.0279). For the DLBCL population, the mean LOS was 24.47 days (95% CI: 19.22 to 29.71) with malnutrition and 17.17 days (95% CI: 13.29 to 21.04, p = 0.0161) without malnutrition. The NHL population excluding DLBCL exhibited a mean LOS of 33.86 days (95% CI: 22.66 to 45.07) for malnourished patients and 17.44 days (95% CI: 14.76 to 20.11, p = 0.0055) for non-malnourished patients. The myeloma population showed a similar trend although not statistically significant, with a mean LOS of 39.00 days (95% CI: -3.54 to 81.54) for malnourished patients and 18.03 days (95% CI: 15.02 to 21.03, p = 0.3337) for non-malnourished patients. These findings highlight significant variations in LOS across different CAR-T-treated cancer subtypes, emphasizing the impact of malnutrition on healthcare resource utilization in oncology. Conclusion Malnutrition is associated with a significantly longer hospital stay among patients undergoing CAR-T therapy. This trend is consistent across various subpopulations, including those with ALL, DLBCL, and NHL (excluding DLBCL). While the impact of malnutrition on LOS was not statistically significant in the myeloma population, this could potentially be attributed to the smaller sample size in this group. Overall, these findings underscore the critical role of nutritional status in managing patients undergoing CAR-T therapy. Future studies should investigate the most effective methods for identifying and treating malnutrition in this patient population to reduce hospital stays and optimize overall patient care.
