A real-world assessment of healthcare costs associated with agitation in Alzheimer's dementia.

AIMS: To describe and compare clinical characteristics, healthcare costs, and institutionalization/mortality outcomes among patients with and without agitation associated with Alzheimer's dementia (AAD). METHODS: Data from the Reliant Medical Group database (01/01/2016-03/31/2020) were used, including claims, electronic medical records, and clinical information/physician notes abstracted from medical charts. Patients aged ≥55 years with Alzheimer's dementia (AD) were observed during a randomly selected 12-month study period after AD diagnosis. Using information recorded in medical charts, patients were classified into cohorts based on experiencing (agitation cohort) and not experiencing (no agitation cohort) agitated behaviours during the study period. Entropy balancing was used to create reweighted cohorts with similar characteristics. Study outcomes (patient demographic and clinical characteristics, treatments received, healthcare costs, institutionalization and death events) were compared between cohorts; agitation characteristics were described for the agitation cohort only. RESULTS: Among 711 patients included in the study, 240 were classified in the agitation cohort and 471 in the no agitation cohort. After reweighting, several comorbidities were more frequently observed in the agitation versus no agitation cohort, including infection, depression, and altered mental status. Use of antidepressants, anticonvulsants, antipsychotics, and antianxiety medications was more common in the agitation versus no agitation cohort. Common agitated behaviours included hitting (20.8%), pacing/aimless wandering (17.5%), and cursing/verbal aggression (15.0%). Total all-cause healthcare costs were $4287 per-patient-per-year higher in the agitation cohort versus no agitation cohort (p = 0.04), driven by higher inpatient costs. Death was more common and time to death and institutionalization were shorter in the agitation versus no agitation cohort. LIMITATIONS: Results may not be generalizable to the US population with AD. CONCLUSIONS: Among patients with AD, agitation was associated with shorter time to death/institutionalization and increased comorbidities, medication use, and healthcare costs, highlighting the additional clinical and economic burden that agitation poses to patients and the healthcare system.

Real-world economic and clinical outcomes associated with current hemostatic matrix use in spinal surgery.

Aim: Bleeding during spine surgery is controlled using topical hemostatic agents. Studies have reported outcomes between Surgiflo® and Floseal, the most widely used flowable hemostatic matrices, but have not included the latest Surgiflo formulation which is more adherent to the bleeding surface than prior formulations. Materials & methods: A propensity score-matched analysis was conducted using the Premier Healthcare Database to compare economic and clinical outcomes of adults undergoing inpatient spinal surgery between 2013 and 2018 receiving current Surgiflo or Floseal. Results: This retrospective study included 28,910 patients in each group and found comparable outcomes for bleeding events, overall transfusion rate, inpatient mortality and readmissions between Surgiflo and Floseal. Surgiflo was associated with $430 (USD) lower hospitalization costs, shorter length of stay and shorter operating room time than Floseal.

Topical hemostatic agents such as Surgiflo^® and Floseal are used during invasive surgery to manage bleeding. We compared outcomes of spine surgeries that used either of two most frequently used topical hemostatic agents, Surgiflo or Floseal. This is the largest retrospective study presenting economic and clinical outcomes of patients receiving Surgiflo versus Floseal during spine surgery using the latest product formulations. The study suggests that clinical outcomes are comparable between Surgiflo and Floseal groups and that Surgiflo is associated with lower hospitalization costs, slightly shorter hospital stay and shorter operating room time among patients undergoing spine surgery.

Retrospective Database Analysis to Explore Patterns and Economic Burden of Switchback to Brand After Generic or Authorized Generic Utilization.

Background: Despite demonstration of bioequivalence of generics to brands and the potential for reduced costs, some patients switch back from a generic to the brand. A prior retrospective analysis suggested that this switchback rate may be lower among patients that had initially switched to authorized generics (AG), often both produced and marketed by the brand company, compared to those initially switched to another generic. Objective: Explore switching patterns of brands, AGs, and generics, switchback rates, and the potential impact of switchbacks on healthcare costs. Methods: An analysis of the Pharmetrics Plus™ database (2007-2019), a United States (US) payer administrative database, was conducted to examine the use of Upjohn medications available as AGs across multiple therapeutic areas. Patients initiating treatment with brand medication in the 6 months prior to generic market entry were identified and switch rates to generics and AGs, as well as switchback rates, were evaluated. Costs were descriptively compared between patients who switched back to brand and those who remained on any generic. Results: Across 14 brand medications, more than half of the patients initiating treatment with the brand medication were switched to a generic. Generally, switching to AG, which ranged from 0.5 to 39.6%, was lower than switching to non-AG generics (16.7-79.9%). The comparison of switchback rates from AGs to brand and non-AGs to brand showed similar results (AG:1.3-7.5%; non-AG:1.4-12.9%); however, the most substantial differences were observed where non-AG switchbacks were higher. Patients that switched back to brand remained on AG or generic for an average of 1-3 months (32-88 days). The analysis showed a tendency towards increased medical costs in the period immediately preceding switchback for all medications except sildenafil in both indications (erectile dysfunction and pulmonary arterial hypertension). For the remaining medications, medical costs ranged from $63 to $1544 higher for the switchback population. Pharmacy costs similarly tended to be higher for patients who had a switchback, with the exception of sildenafil for pulmonary arterial hypertension and sirolimus. Conclusion: Patients receiving a brand medication are likely to be switched to a generic upon market availability. Some patients switch back to the brand medication, usually within 1-3 months; this may be associated with increased medical costs. Additional research is needed to understand switching, its potential disruption to patients, and the role of brands, generics, and AGs.

Real-World Clinical and Economic Outcomes Associated with Surgiflo® vs Floseal in Cardiovascular Surgeries in the US.

Background: Topical hemostatic agents are an option for controlling bleeding during cardiovascular surgery. Previous studies comparing topical hemostatic agents in cardiovascular surgery predate the 2012 reformulation of Surgiflo®, which had been re-engineered to increase paste viscosity and thus be more adherent to the bleeding surface. Objective: To compare clinical and economic outcomes in patients receiving the current formulation of Surgiflo vs Floseal during cardiovascular surgeries. Methodology: A retrospective analysis was conducted using the Premier Healthcare Database. Eligible patients had an inpatient cardiovascular surgery between 1/1/2013 and 6/1/2018, were ≥18 years old and received the current formulation of Surgiflo or Floseal during surgery. Propensity score matching was performed, with exact matching on the surgery year and surgery type (aortic, coronary artery bypass grafting, valve, or other). Descriptive analysis and generalized estimating equations models compared outcomes between the Surgiflo and Floseal groups. Results: The matched sample included 5768 patients in each group (mean age: 66.5 years; 66.3% male). In the matched sample, rates of any documented bleeding event were similar in Surgiflo and Floseal groups (6.9% vs 7.2%; P = 0.576). Differences in transfusion rates between patients receiving Surgiflo vs Floseal varied by operational definition and timing of measurement but did not differ by >2 percentage points. Compared to Floseal, patients who received Surgiflo experienced longer surgery duration (306.0 vs 299.4 minutes), lower hospitalization cost ($44,146 vs $46,812), and lower odds of readmission at 30, 60, and 90 days post-discharge (all P < 0.05). Inpatient mortality and LOS were comparable between Surgiflo and Floseal (all P > 0.05). Conclusion: In this large study of real-world clinical and economic outcomes after cardiovascular surgery involving the current formulation of Surgiflo vs Floseal, Surgiflo was associated with mostly similar clinical outcomes as compared with Floseal. Differences in selected economic/resource use outcomes were also observed, for which root-cause analysis in future research would be informative.

Cost impact of hydroxocobalamin in the treatment of patients with known or suspected cyanide poisoning due to smoke inhalation from closed-space fires.

BACKGROUND & OBJECTIVES: Cyanide poisoning can occur due to exposure to smoke in closed-space fires. With no point of care cyanide test at the scene of a fire, first responders and clinicians base decisions to treat with cyanide antidote on patient history, clinical signs, and other indirect data points that have not been proven to correspond with actual systemic levels of cyanide. The aim of this exploratory study was to determine the economic implications of treating patients with known or suspected cyanide poisoning due to smoke inhalation with hydroxocobalamin. METHODS: A decision analysis model was developed from the US hospital perspective. Healthcare resource utilization was estimated from a retrospective evaluation of clinical outcomes in hydroxocobalamin-treated patients and in historical controls without hydroxocobalamin use (Nguyen, et al. 2017). Epidemiologic parameters and costs were estimated from the published literature, and publicly-available hospital charges were identified. Outcomes reported in the analysis included expected healthcare resource utilization in the US population and per-patient costs with and without the use of hydroxocobalamin. A cost-to-charge ratio was applied so that all costs would reflect hospital costs rather than hospital charges. Deterministic sensitivity analysis was performed to identify the most influential model parameters. All costs were reported in 2017 US dollars. RESULTS: Use of hydroxocobalamin reduces healthcare resource utilization and contributes to decreased per-patient hospital costs ($15,381 with hydroxocobalamin treatment versus $22,607 with no cyanide antidote). The most substantive cost-savings resulted from decreased hospital length of stay (i.e., intensive care unit [ICU] and non-ICU). Costs attributed to mechanical ventilation also decreased with use of hydroxocobalamin. A univariate sensitivity analysis demonstrated that the most impactful variables in the cost analysis were related to hospital length of stay (ICU followed by non-ICU stay), followed by the daily cost of ICU stay. CONCLUSIONS: Use of hydroxocobalamin in patients with known or suspected cyanide poisoning from closed-space fire smoke inhalation may decrease hospital costs and contribute to more efficient healthcare resource utilization.

Cost-Minimization Analysis of Dexmedetomidine Compared to Other Sedatives for Short-Term Sedation During Mechanical Ventilation in the United States.

PURPOSE: Mechanical ventilation (MV) remains a substantial cost driver in intensive care units (ICU) in the United States (US). Evaluations of standard sedation treatments used to relieve pain and discomfort in this setting have found varying impacts on ICU length of stay. This cost analysis examines both length-of=stay costs and the total cost implications among MV patients receiving common sedative treatments (dexmedetomidine, propofol, or midazolam) in short-term sedation settings (<24 hours). METHODS: A cost-minimization model was conducted from the hospital provider perspective. Clinical outcomes were obtained from published literature and included ICU length of stay, MV duration, prescription of sedatives and pain medication, and the occurrence of adverse events. Outcomes costs were obtained from previously conducted ICU cost studies and Medicare payment fee schedules. All costs were estimated in 2018 US Dollars. RESULTS: The per patient costs associated with dexmedetomidine, propofol, and midazolam were estimated to be $21,115, $27,073, and $27,603, respectively. Dexmedetomidine was associated with a savings of $5958 per patient compared to propofol and a saving of $6487 compared to midazolam. These savings were primarily driven by a reduction in ICU length of stay and the degree of monitoring and management. CONCLUSION: Dexmedetomidine was associated with reduced costs when compared to propofol or midazolam used for short-term sedation during MV in the ICU, suggesting sedative choice can have a potential impact on overall cost per episode.

Cost-Effectiveness of Early Treatment with Originator Biologics or Their Biosimilars After Methotrexate Failure in Patients with Established Rheumatoid Arthritis.

INTRODUCTION: Evidence supports the clinical benefits of early aggressive biologic treatment in patients with rheumatoid arthritis (RA) who have an inadequate response to conventional synthetic disease-modifying antirheumatic drugs (csDMARDs), but the cost-effectiveness of early intervention with originator biologics such as tumor necrosis factor inhibitors (TNFis) or their biosimilars has not been well studied. METHODS: We developed a Markov model to estimate lifetime costs and utilities for patients with established RA who do not respond to methotrexate (MTX) therapy. A cost-effectiveness analysis was conducted comparing a standard intervention pathway (addition of originator biologic TNFis to MTX monotherapy at 12 months) and two early intervention pathways (either addition of originator biologic TNFis or addition of biosimilar TNFis to MTX monotherapy at 6 months). RESULTS: Early intervention with an originator biologic TNFi at 6 months was associated with increases in total lifetime costs of £1692 and utilities of 0.10 quality-adjusted life-years (QALYs) per patient compared with standard intervention at 12 months, resulting in an incremental cost-effectiveness ratio (ICER) of £17,335/QALY. Early intervention with a biosimilar TNFi increased costs by £70 and utilities by 0.10 QALYs per patient and was associated with an ICER of £713/QALY. CONCLUSION: Switching from MTX monotherapy to combination therapy with either an originator biologic or biosimilar TNFis at 6 months after csDMARD failure in patients with RA was cost-effective at a threshold of £30,000/QALY.

Impact of subsequent metastases on costs and medical resource use for prostate cancer patients initially diagnosed with localized disease.

BACKGROUND: The impact of subsequent metastases on costs and medical resource use (MRU) for prostate cancer (PC) patients initially diagnosed with localized disease was estimated. METHODS: Surveillance, Epidemiology, and End Results data, linked to Medicare (1999-2012), were used to identify 7482 patients diagnosed with subsequent metastases 12 months or more after the initial diagnosis of localized PC (cases), and they were matched to 25,709 localized PC patients without subsequent metastases (controls). Patients were followed for costs and MRU from 12 months before their index date (subsequent metastases or a matched date for controls) up to 12 months after it. Costs and MRU were stratified by the setting/type of care/service. Multivariate mixed effects regression analyses were used to construct and compare longitudinal trajectories of marginal predicted costs and predicted probabilities of MRU between cases and controls. RESULTS: Among the controls, predicted monthly costs remained relatively stable throughout the entire observation period (weighted mean per patient per month, $2746; range during 24 months, $2603-2858). In contrast, among the cases, costs increased from $2622 (95% confidence interval [CI], $2525-2719) 12 months before the diagnosis of subsequent metastases to $4767 (95% CI, $4623-4910) 1 month before the diagnosis of subsequent metastases, peaked during the month of metastases at $13,291 (95% CI, $13,148-13,435), and remained significantly higher than costs for the controls thereafter (eg, $4677 at + 12 months; 95% CI, $4549-4805). Costs and MRU increased across a wide range of settings/types, including inpatient, outpatient, home health, and hospice settings. CONCLUSIONS: In PC patients initially diagnosed with localized disease, a diagnosis of subsequent metastases is associated with substantially increased costs and MRU.

Assessment of motivating factors associated with the initiation and completion of treatment for chronic hepatitis C virus (HCV) infection.

BACKGROUND: Infection with hepatitis C virus (HCV) is associated with high morbidity and increased mortality but many patients avoid initiation of treatment or report challenges with treatment completion. The study objective was to identify motivators and barriers for treatment initiation and completion in a community sample of HCV-infected patients in the United States. METHODS: Survey methods were employed to identify factors reported by patients as important in their decision to start or complete HCV treatment. Study participants included 120 HCV-infected individuals: 30 had previously completed treatment with pegylated interferon/ribavirin (PR), 30 had discontinued PR, 30 were treated with PR at the time of the survey, and 30 were treatment‒naïve. Telephone interviews occurred between May and August of 2011 and employed a standardized guide. Participants assigned factors a rating from 1 (not at all important) to 5 (extremely important). Trained researchers coded and analyzed interview transcripts. RESULTS: Of 33 factors, expected health problems from not treating HCV infection was reported as most encouraging for treatment initiation and completion, while treatment side effects was most discouraging. Sixty-nine percent of participants reported that the ability to obtain information during treatment on the likelihood of treatment success (i.e., results of viral load testing) would motivate them to initiate therapy. Median preferred timing for learning about test results was 5 weeks (range: 1-23 weeks). CONCLUSION: Understanding challenges and expectations from patients is important in identifying opportunities for education to optimize patient adherence to their HCV treatment regimen.

Impact of drug coverage on medical expenditures among the elderly.

Our study compares expenditures for Medicare covered medical services among enrollees in three State pharmacy assistance programs with spending among low-income residents eligible or near-eligible for, but not enrolled in such State-sponsored programs after controlling for between-group differences in demographic, socioeconomic, health status, and insurance status characteristics. We estimate a two-part model in total and by type of service (inpatient, outpatient, and professional) and chronic condition (hypertension, heart disease, and arthritis). We find that drug coverage has no discernible effect on the use and cost of inpatient services, but is associated with a statistically significant increase in Medicare spending for physician services.

The economic burden of schizophrenia in the United States in 2002.

OBJECTIVE: This study quantifies excess annual costs associated with schizophrenia patients in the United States in 2002 from a societal perspective. METHOD: Annual direct medical costs associated with schizophrenia were estimated separately for privately (N = 1090) and publicly (Medicaid; N = 14,074) insured patients based on administrative claims data, including a large private claims database and the California Medicaid program (MediCal) database, and compared separately to demographically/geographically matched control samples (1 case:3 controls). Medicare costs of patients over age 65 years were imputed using the Medicare/MediCal dual-eligible patients (N = 1491) and published statistics. Excess annual direct non-health care costs were estimated for law enforcement, homeless shelters, and research/training related to schizophrenia. Excess annual indirect costs were estimated for 4 components of productivity loss: unemployment, reduced workplace productivity, premature mortality from suicide, and family caregiving using a human capital approach based on market wages. All costs were adjusted to 2002 dollars using the Medical Care Consumer Price Index and were based on the reported prevalence in the National Comorbidity Survey Replication. RESULTS: The overall U.S. 2002 cost of schizophrenia was estimated to be $62.7 billion, with $22.7 billion excess direct health care cost ($7.0 billion outpatient, $5.0 billion drugs, $2.8 billion inpatient, $8.0 billion long-term care). The total direct non-health care excess costs, including living cost offsets, were estimated to be $7.6 billion. The total indirect excess costs were estimated to be $32.4 billion. CONCLUSION: Schizophrenia is a debilitating illness resulting in significant costs. The indirect excess cost due to unemployment is the largest component of overall schizophrenia excess annual costs.
