Direct and Indirect Costs of Refractory Epilepsy in a Tertiary Epilepsy Center in Germany

Population-Based Analysis of 6534 Seizure Emergency Cases from Emergency Medical Services Data

INTRODUCTION

Seizures are common reasons to call an ambulance, and this study aims to analyze the burden of seizures in the prehospital setting based on incidence, hospital admission rate, and costs.

METHODS

This was a population-based, cross-sectional analysis of prehospital emergency medical services (EMS) data on suspected seizure cases from the federal state of Hesse, Germany, in 2019.

RESULTS

A total of 6534 suspected seizure cases were identified, of which most were those with a known seizure disorder. Incidence rate for epilepsy-related seizures (ES; pediatric epilepsy, first seizure [1stS], seizure with known seizure disorder [SEPI]) was 205.7 per 100,000 inhabitants and incidence rate for pediatric febrile seizures (PFS) was 36.7 per 100,000 inhabitants, corresponding to 171,275 ES and 28,500 PFS (99.3% < 18 years) cases in Germany. A prehospital EMS physician was involved in 40.0% (SEPI) to 54.4% (PFS) of suspected seizure cases. Depending on the type of seizure, 70.7% (SEPI) to 80.9% (1stS) were admitted to hospital for inpatient stay of ≥ 24 h. An additional 4% (PFS) to 16% (1stS) of cases needed immediate intervention at hospital. Prehospital EMS staff needed 8:24 min:s (SD 7:24; n = 5004) after the emergency call to arrive at the scene of the ES and 10:58 min:s (SD 27:39; n = 321) for PFS. ES and PFS cases caused estimated costs of 48.5 and 8.1 million euros for Germany in 2019, respectively, not including hospital treatment-related costs.

CONCLUSION

This study identified a high number of suspected seizure-related emergency cases and proportion of patients admitted to hospitals, as well as high associated costs in Germany.

Prevalence of and factors associated with the early prescription of antiseizure medications in adults newly diagnosed with epilepsy in Germany

BACKGROUND

There is little information on prescription patterns of antiseizure medications (ASMs) during the early management of patients with epilepsy in Germany. Therefore, this study investigated the prevalence of and the factors associated with ASM prescription in patients newly diagnosed with epilepsy in this country.

METHODS

Adults diagnosed for the first time with epilepsy in one of 128 neurology practices in Germany between 2005 and 2021 were included (Disease Analyzer database, IQVIA). The prescription of ASMs was assessed within 30 days, six months, and 12 months of the diagnosis. Covariates were demographic factors, epilepsy sub-diagnoses, and co-diagnoses frequently associated with epilepsy.

RESULTS

This study included 55,962 participants (mean [SD] age 52.5 [20.0] years; 50.5 % men). The prevalence of ASM prescription ranged from 45.0 % within 30 days to 66.0 % within 12 months of the diagnosis. Men were less likely to receive ASMs within six and 12 months of epilepsy diagnosis than women. In addition, epilepsy sub-diagnoses of symptomatic, complex, or generalized nature were associated with increased odds of ASM prescription compared with epilepsy of unspecified nature. Finally, there was an inverse and significant association between multiple co-diagnoses (e.g., diabetes, mental and behavioral disorders due to use of alcohol, and traumatic brain injury) and ASM prescribing.

CONCLUSIONS

A substantial proportion of participants were prescribed ASMs in the year following epilepsy diagnosis, highlighting that the early prescription of ASMs was necessary for these patients. Further research is warranted to corroborate the present findings in other countries and settings.

Clinical and economic implications of epilepsy management across treatment lines in Spain: a real-life database analysis

BACKGROUND

Epilepsy is a chronic brain disease characterized by recurrent seizures. We investigated real-world management of epilepsy across treatment lines in Spain, including healthcare resource use (HRU) and associated costs.

METHODS

This was a retrospective study of real-life data from epilepsy patients prescribed antiseizure medication (ASM) between January 2016 and December 2021. Patients were grouped according to their line of treatment (1st, 2nd, 3rd and 4th +) during the recruitment period. Demographic and clinical characteristics, comorbidities and concomitant medications were analyzed during the baseline period (6 months before starting treatment line); antiepileptic treatments, concomitant medications, HRU and associated costs were analyzed during follow-up.

RESULTS

The study included 5006 patients. Treatment duration decreased as treatment lines progressed (mean ± SD progression time: 523.2 ± 279.1 days from 1st to 2nd line, 351.6 ± 194.4 days from 2nd to 3rd line; 272.7 ± 139.3 days from 3rd to 4th + line). Significant HRU differences were found with subsequent treatment lines, including an increase in hospital admissions and patients on sick leave. Mean (95% CI) adjusted total costs per patient were €2974/year (2773-3175) in the 1st line and €5735/year (5043-6428) in the 4th + line. There was an increase in adjusted direct and total costs with subsequent treatment lines; the mean difference in total costs between cohorts was €2761 (p < 0.001). The highest direct costs were associated with epilepsy medication, days at the hospital and specialist visits.

CONCLUSION

Our data revealed a progressive increase in the use of resources and associated costs across subsequent epilepsy treatment lines.

Unemployment and early retirement among patients with epilepsy - A study on predictors, resilience factors and occupational reintegration measures

The primary aim of this study was to identify predictors and resilience factors for unemployment and early retirement in patients with epilepsy of working age based on data from a multicenter German cohort study performed in 2020 (n = 456) by using multivariate binary logistic regression analysis. A second aim was to assess the assumed working ability of patients as well as the use of occupational reintegration measures. The unemployment rate was 8.3%, and 18% of patients had retired early due to epilepsy. Multivariate binary logistic regression analysis identified the presence of a relevant disability and frequent seizures as significant predictors of unemployment and early retirement, while seizures in remission were the only resilience factor associated with job retention. Regarding occupational incapacity, at the time of the survey, most of the patients in early retirement or unemployment were fit for work in their original or extended occupational setting. The proportion of patients with recent epilepsy-related occupational retraining (0.4%) or job changes (0.9%) was low, and only 2.4% reported an epilepsy-related reduction in work time. These findings underline the persistent disadvantage of patients with epilepsy in the professional field and the urgent need for effective, comprehensive work reintegration measures that must be made accessible for all patients.

Epilepsy and Attention Deficit Hyperactivity Disorder: Connection, Chance, and Challenges

Comorbidities are common in children with epilepsy, with nearly half of the patients having at least one comorbidity. Attention deficit hyperactivity disorder (ADHD) is a psychiatric disorder characterized by hyperactivity and inattentiveness level disproportional to the child’s developmental stage. The burden of ADHD in children with epilepsy is high and can adversely affect the patients’ clinical outcomes, psychosocial aspects, and quality of life. Several hypotheses were proposed to explain the high burden of ADHD in childhood epilepsy; the well-established bidirectional connection and shared genetic/non-genetic factors between epilepsy and comorbid ADHD largely rule out the possibility of a chance in this association. Stimulants are effective in children with comorbid ADHD, and the current body of evidence supports their safety within the approved dose. Nonetheless, safety data should be further studied in randomized, double-blinded, placebo-controlled trials. Comorbid ADHD is still under-recognized in clinical practice. Early identification and management of comorbid ADHD are crucial to optimize the prognosis and reduce the risk of adverse long-term neurodevelopmental outcomes. The identification of the shared genetic background of epilepsy and ADHD can open the gate for tailoring treatment options for these patients through precision medicine.

Antiseizure medication and perceived "fair" cost allocation: a factorial survey among neurologists, persons with epilepsy, their relatives and a control group

OBJECTIVE

As resources are limited in modern healthcare systems, the decision on the allocation of expensive drugs can be supported by a public consent. This study examines how various factors influence subjectively perceived "fair" pricing of antiseizure medication (ASM) among four groups including physicians, persons with epilepsy (PWE), their relatives and a control group.

METHODS

We conducted a factorial survey. Vignettes featured a fictional PWE receiving a fictional ASM. The characteristics of the fictional PWE, ASM and epilepsy varied. Participants were asked to assess the subjectively appropriate annual cost of ASM treatment per year for each scenario.

RESULTS

57 PWE (age 37.7 ± 12.3, 45.6 % females), 44 relatives (age 48.4 ± 15.7, 51.1 % females), 46 neurologists (age 37.1 ± 9.6, 65.2 % females) and 47 persons in the control group (age 31.2 ± 11.2, 68.1 % females) completed the questionnaire. The amount of money that respondents were willing to spend for ASM-treatment was higher than currently needed in Germany and increased with disease severity among all groups. All groups except for PWE accepted higher costs of a drug with better seizure control. Physicians and the control group, but not PWE and their relatives, tended to do so also for minor or no side effects. Physicians reduced the costs for unemployed patients and the control group spent less money for older patients.

SIGNIFICANCE

ASM effectiveness appears to justify higher costs. However, the control group attributed less money to older PWE and physicians allocated fewer drug costs to unemployed PWE.

Trends in resource utilization and cost of illness in patients with active epilepsy in Germany from 2003 to 2020

OBJECTIVE

To calculate epilepsy-related direct, indirect, and total costs in adult patients with active epilepsy (ongoing unprovoked seizures) in Germany and to analyze cost components and dynamics compared to previous studies from 2003, 2008 and 2013. This analysis was part of the Epi2020 study.

METHODS

Direct and indirect costs related to epilepsy were calculated with a multicenter survey using an established and validated questionnaire with a bottom-up design and human capital approach over a 3-month period in late 2020. Epilepsy-specific costs in the German health care sector from 2003, 2008 and 2013 were corrected for inflation to allow for a valid comparison.

RESULTS

Data on the disease-specific costs for 253 patients in 2020 were analyzed. The mean total costs were calculated at € 5,551 (± € 5,805; median: € 2,611; range: € 274 to € 21,667) per three months, comprising mean direct costs of € 1,861 (± € 1,905; median: € 1,276; range: € 327 to € 13,158) and mean indirect costs of € 3,690 (± € 5,298; median: € 0; range: € 0 to € 11,925). The main direct costs components were hospitalization (42.4%), anti-seizure medication (42.2%) and outpatient care (6.2%). Productivity losses due to early retirement (53.6%), part-time work or unemployment (30.8%) and seizure-related off-days (15.6%) were the main reasons for indirect costs. However, compared to 2013, there was no significant increase of direct costs (-10.0%), and indirect costs significantly increased (p<0.028, +35.1%), resulting in a significant increase in total epilepsy-related costs (p<0.047, +20.2%). Compared to the 2013 study population, a significant increase of cost of illness could be observed (p=0.047).

SIGNIFICANCE

The present study shows that disease-related costs in adult patients with active epilepsy increased from 2013 to 2020. As direct costs have remained constant, this increase is attributable to an increase in indirect costs. These findings highlight the impact of productivity loss caused by early retirement, unemployment, working time reduction and seizure-related days off.

EuroQOL-5D-3L does not adequately map quality-of-life deterioration in severely affected patients with epilepsy

INTRODUCTION

The steadily increasing impact of health-related quality of life (HRQOL) on reasonable diagnostic and therapeutic decisions makes the correct mapping of HRQOL indispensable in modern epileptology. The aim of this study was to address the reliability of the often-used generic HRQOL screening questionnaire EuroQOL 5-dimension, 3-level (EQ-5D-3L) by comparing its normalized index value (calculated via the time trade-off method) and visual analog scale (VAS) to the gold standard of the extensive Quality of Life in Epilepsy Inventory (QOLIE-31). QOLIE-10 scores were compared with the extensive QOLIE-31 and EQ-5D-3L TTO.

METHODS

We conducted a retrospective analysis of a monocentric study of 184 patients with epilepsy. Bivariate Spearman correlation analysis and Fisher's r-to-z transformation were used to compare the strengths of correlations of EQ-5D-3L, QOLIE-10 and QOLIE-31 with different epilepsy-specific domains (disease severity, drug interactions, emotional well-being, stigmatization, seizure-related anxiety, cognitive impairment).

RESULTS

The different metrics of EQ-5D-3L, QOLIE-10 and QOLIE-31 showed moderate to very strong intra- and inter-metric correlations for overall HRQOL. Quality of Life in Epilepsy Inventory-31 VAS and EQ-5D-3L VAS did not show any significantly different strengths of correlations with respect to the domains studied. In contrast, the correlation strength of the normalized EQ-5D-3L index value differed significantly from the QOLIE-31 T-score for several domains, for example, for drug-related adverse events, neuropsychological deficits, symptoms of depression and seizure worry. In seizure-free patients, EQ-5D-3L VAS and EQ-5D-3L index values correlated significantly less with the domain of "cognitive impairment" than the QOLIE-31 T-score. In patients without relevant neuropsychological deficits, the strengths of correlations with the assessed domains did not differ significantly between EQ-5D-3L metrics and the QOLIE-31 T-score. The HRQOL mapping probability of QOLIE-10 was inferior to QOLIE-31 and comparable to EQ-5D-3L regarding the analyzed domains.

CONCLUSION

In contrast to the EQ-5D-3L VAS, EQ-5D-3L index values do not adequately map health-related quality of life in severely affected patients with epilepsy and therefore should not be used as screening tools. The QOLIE-31 T-score remains the gold standard for HRQOL assessment in patients with epilepsy.

Economic evaluation of deep brain stimulation compared with vagus nerve stimulation and usual care for patients with refractory epilepsy: A lifetime decision analytic model

OBJECTIVES

This study was undertaken to estimate the cost-effectiveness of deep brain stimulation (DBS) compared with vagus nerve stimulation (VNS) and care as usual (CAU) for adult patients with refractory epilepsy from a health care perspective using a lifetime decision analytic model.

METHODS

A Markov decision analytic model was constructed to estimate the lifetime cost-effectiveness of DBS compared with VNS and CAU. Transition probabilities were estimated from a randomized controlled trial, and assumptions were made in consensus with an expert panel. Primary outcomes were expressed as incremental costs per quality-adjusted life-year (QALY) and per responder. Univariate and probabilistic sensitivity analyses were conducted to characterize parameter uncertainty.

RESULTS

In DBS, 28.4% of the patients were responders, with an average of 21.38 QALYs per patient and expected lifetime health care costs of €187 791. VNS had fewer responders (22.3%), fewer QALYs (20.70), and lower lifetime costs (€156 871). CAU had the fewest responders (6.2%), fewest QALYs (18.74), and lowest total health care costs (€64 670). When comparing with CAU, incremental cost-effectiveness ratios (ICERs) showed that costs per QALY gained were slightly lower for DBS (€46 640) than for VNS (€47 155). When comparing DBS with VNS, an incremental cost per additional QALY gained of €45 170 was found for DBS. Sensitivity analyses showed that ICERs were heavily dependent on assumptions regarding loss to follow-up in the respective clinical trial.

SIGNIFICANCE

This study suggests that, given current limited evidence, VNS and DBS are potentially cost-effective treatment strategies compared to CAU for patients with refractory epilepsy. However, results for DBS were heavily impacted by assumptions made to extrapolate nonresponse from the original trial. More stringent assumptions regarding nonresponse resulted in an ICER just above an acceptable willingness to pay threshold. Given the uncertainty surrounding the effectiveness of DBS and the large impact of assumptions related to nonresponse, further empirical research is needed to reduce uncertainty.

[Admission diagnosis contusion: etiology, epidemiology and cost-causing factors]

BACKGROUND

The admission of patients with minor injuries, such as contusions is a regular practice in acute care hospitals. The pathophysiological changes resulting from the accident are seldom the primary reason for hospitalization. The aim of this retrospective monocentric study was therefore to examine the etiology as well as the cost-causing factors and refinancing on admission.

METHODS

Patients were identified due to a retrospective query in the hospital information system (HIS) according to the ICD-10 German modification codes at discharge. A total of 117 patients were enrolled over a period of 2 years. The classification was carried out according to the accident mechanism and the division into age groups. In addition, the cost calculation was based on department and clinic-specific daily rates.

RESULTS

In terms of etiology low impact falls in the domestic environment were the most common cause (48.7%), followed by high-energy trauma (22.8%). Within the group with domestic falls, the mean age was 77.8 years. This group also showed the longest length of stay (LOS) with 5.2 days. As part of the calculated costs, the group of domestic falls showed the highest costs of 2596.24 € with an average DRG cost revenue of 1464.51 €.

DISCUSSION

The evaluation of the clinic internal data confirmed the subjective perception that the majority of patients admitted with the diagnosis of contusions came from the age group >65 years. Admission is primarily based on the increasing comorbidities and to avert secondary diseases and the consequences of immobilization. It could also be shown that the resulting costs are relevant to health economics and that the treatment does not appear to cover the costs.

Cost of Illness of Epilepsy and Associated Factors in Patients Attending Adult Outpatient Department of University of Gondar Referral Hospital, Northwest Ethiopia

Background

Epilepsy has significant economic implications on health care needs, premature death, and lost work productivity. Therefore, this study aimed to assess the cost of illness of epilepsy and its associated factors in the Outpatient Department of University of Gondar Referral Hospital, Northwest Ethiopia.

Methods

We conducted an institution-based cross-sectional study from March 2018 to April 2018. A total of 442 adult epileptic patients were selected from the chronic follow-up clinic using a systematic sampling technique. We fitted binary logistic regression to identify the associated factors, and significant variables in the multivariable logistic regression analysis were determined using P-value <0.05 and 95% CI.

Results

The study revealed that the mean total cost illness of epilepsy per patient per year was US$ 166±61.6, and 30.3% of patients incurred high cost. Age (AOR = 1.06; 95% CI: 1.03, 1.09), sex (AOR = 3.66; 95% CI: 1.94, 6.89), educational (AOR = 0.15; 95% CI: 0.005, 0.047), polytherapy (AOR = 4.66; 95% CI: 2.29, 9.46), seizure frequency (AOR = 4.48; 95% CI: 1.56, 12.8), place where AEDs were bought (AOR = 6.23; 95% CI: 2.7, 14.03) and disease duration (AOR = 0.11; 95% CI: 0.05, 0.25) were predictors of the cost of illness of epilepsy.

Conclusion

The total annual cost of illness of epilepsy was high, taking into account the per capita income of the individuals. The age, sex, and educational status of the patients, and the number of AED, seizure frequency, places where patients buy drugs, and disease duration were factors significantly associated with the cost of illness of epilepsy. Hence, creating an alternative source of income, socio-economic support, and affordable health care service for patients, especially for female and elderly patients, and strengthening and equipping nearby clinics, increasing drug availability in governmental pharmacies.

Costs of Epilepsy in Austria: Unemployment as a primary driving factor

PURPOSE

Epilepsy is one of the most common chronic neurological disorders, and long-term treatment with antiseizure medication is often central to its management. The costs of antiseizure medication are more evident than other disease-related costs; thus, we assessed the direct and indirect costs of epilepsy focusing on both drug expenditure and other cost-driving factors.

METHODS

Outpatient records and questionnaires applied in a tertiary epilepsy centre in Vienna were used in this bottom-up cost-of-illness study to evaluate disease duration, age at onset, epilepsy syndrome, seizure frequency, sex, healthcare utilisation, diagnostic evaluations, antiseizure medication, and occupation. Cost data were clustered in a histogram-based data analysis, and multivariate regressions were performed to identify cost drivers.

RESULTS

The average annual costs of 273 patients amounted to €9,256 ($10,459): €4,486 ($5,069) direct costs and €4,770 ($5,390) indirect costs. A histogram of semi-annual costs revealed distinct groups with low costs (< €2,500 = $2,825) and high costs (> €2,500 = $2,825). Seizure-free patients were clustered in the group with low costs; patients with ongoing seizures appeared more frequently in the group with high costs. Working patients were more often found in the group with low costs, whereas unemployed patients were more prevalent in the group with high costs. The regression analysis confirmed worklessness as the main cost driver.

CONCLUSION

Non-productivity and poorly controlled disease with ongoing seizures are associated with higher costs in epilepsy. Providing high-level care and optimal drug treatment that enables patients to remain in work may help reduce the economic burden of epilepsy.

[Inpatient treatment costs, cost-driving factors and potential reimbursement problems due to epileptic seizure-related injuries and fractures]

BACKGROUND

The systematic analysis of disease-specific costs is becoming increasingly more relevant in an economically oriented healthcare system. Chronic diseases are of particular interest due to the long duration as well as frequent hospitalization and physician visits. Epilepsy is a frequent neurological disorder affecting all age groups with the clinical hallmark of paroxysmal epileptic seizures, which are often associated with injuries.

OBJECTIVE

The aim of this work was to process the inpatient treatment costs due to seizure-related injuries and fractures. Moreover, relevant cost-causing factors were addressed. Using an alternative calculation of the costs of care, the question of potential reimbursement problems in the current German diagnosis-related groups (G-DRG) system was additionally assessed.

METHODS

For this monocentric retrospective analysis the actual proceeds of 62 inpatients who were treated at the University Hospital Frankfurt between January 2010 and January 2018 for injuries and fractures due to epileptic seizures were used. The analysis of potential cost-causing factors was carried out with respect to relevant sociodemographic and clinical aspects. The alternative calculation of the costs of treatment was carried out using established health economic methods.

RESULTS

The average DRG revenue was 7408€ (±8993€, median 5086€, range 563-44,519€), the average calculated costs were 9423€ (±11,113€, 5626€, range 587-49,830€). A length of stay ≥7 days (p = 0.014) was identified as a significant cost-driving factor. Due to the significant difference (p < 0.001) between revenue and calculated costs, an analysis was made according to factors for potential reimbursement problems, which remained significant for a length of stay of ≥7 days (p = 0.014) and for treatment in the intensive care unit (p = 0.019).

CONCLUSION

The inpatient treatment costs for patients with injuries and fractures due to epileptic seizures are high and therefore relevant from a health economic perspective. In general, reimbursement according to the G‑DRG appears to cover the actual costs, but there may be reimbursement problems for patients with a long period of hospitalization or a stay in an intensive care ward.

Cost-effectiveness of surgery for drug-resistant temporal lobe epilepsy in the US

OBJECTIVE

Surgery is an effective but costly treatment for many patients with drug-resistant temporal lobe epilepsy (DR-TLE). We aim to evaluate whether, in the United States, surgery is cost-effective compared to medical management for patients deemed surgical candidates and whether surgical evaluation is cost-effective for patients with DR-TLE in general.

METHODS

We use a semi-Markov model to assess the cost-effectiveness of surgery and surgical evaluation over a lifetime horizon. We use second-order Monte Carlo simulations to conduct probabilistic sensitivity analyses to estimate variation in model output. We adopt both health care and societal perspectives, including direct health care costs (e.g., surgery, antiepileptic drugs) and indirect costs (e.g., lost earnings by patients and care providers.) We compare the incremental cost-effectiveness ratio to societal willingness to pay (∼$100,000 per quality-adjusted life-year [QALY]) to determine whether surgery is cost-effective.

RESULTS

Epilepsy surgery is cost-effective compared to medical management in surgically eligible patients by virtue of being cost-saving ($328,000 vs $423,000) and more effective (16.6 vs 13.6 QALY) than medical management in the long run. Surgical evaluation is cost-effective in patients with DR-TLE even if the probability of being deemed a surgical candidate is only 5%. From a societal perspective, surgery becomes cost-effective within 3 years, and 89% of simulations favor surgery over the lifetime horizon.

CONCLUSION

For surgically eligible patients with DR-TLE, surgery is cost-effective. For patients with DR-TLE in general, referral for surgical evaluation (and possible subsequent surgery) is cost-effective. Patients with DR-TLE should be referred for surgical evaluation without hesitation on cost-effectiveness grounds.

General Trends in Prices and Prescription Patterns of Anticonvulsants in Germany between 2000 and 2017: Analysis of National and Cohort-Based Data

OBJECTIVE

Our aim was to explore trends in price evolution and prescription volumes of anticonvulsants (AEDs, antiepileptic drugs) in Germany between 2000 and 2017.

METHOD

This study used data from annual reports on mean prescription frequency and prices of defined daily doses (DDD) of AEDs in Germany to analyze nationwide trends. Interrupted time series (ITS) analysis was employed to test for significant effects of several statutory healthcare reforms in Germany on AED price evolution. These data were compared to cohort-based prescription patterns of four German cohort studies from 2003, 2008, 2013, and 2016 that included a total of 1368 patients with focal and generalized epilepsies.

RESULTS

Analysis of national prescription data between 2000 and 2017 showed that mean prices per DDD of third-generation AEDs decreased by 65% and mean prices of second-generation AEDs decreased by 36%, whereas mean prices of first-generation AEDs increased by 133%. Simultaneously, mean prescription frequency of third- generation AEDs increased by 2494%, while there was a substantial decrease in the use of first- (- 55%) and second- (- 16%) generation AEDs. ITS analysis revealed that in particular the introduction of mandatory rebates on drugs in 2003 affected prices of frequently used newer AEDs. These findings are consistent with data from cohort studies of epilepsy patients showing a general decrease of prices for frequently used AEDs in monotherapy by 62% and in combination therapies by 68%. The analysis suggests that overall expenses for AEDs remained stable despite an increase in the prescription of "newer" and "non-enzyme-inducing" AEDs for epilepsy patients.

CONCLUSION

Between 2000 and 2017, a distinct decline in AED prices can be observed that seems predominately caused by a governmentally obtained price decline of third- and second-generation drugs. These observations seem to be the result of a German statutory cost containment policy applied across all health-care sectors. The increasing use of third-generation AEDs to the disadvantage of "old" and "enzyme-inducing" AEDs reflects the preferences of physicians and patients with epilepsy and follows national treatment guidelines.

Economic and clinical evaluation of vagus nerve stimulation therapy

OBJECTIVES

The medical and social care of drug-resistant epilepsy (DRE) entails significant costs. Approximately 30 to 40 percent of patients with DRE who underwent vagus nerve stimulator (VNS) implantation achieve an above 50 percent reduction in seizure frequency. The study objective was to analyze the effect of VNS on clinical effects improvement and therapy cost reduction in patients with DRE over a 2-year follow-up period. The second purpose of the study was to compare average costs of VNS treatment of patients with DRE in selected countries, taking into account the purchasing power parity.

MATERIALS AND METHODS

The study included all the patients who had VNS implanted at our department between 2014 and 2018. Data on clinical events and medical costs were collected prospectively and obtained from medical documentation. We also reviewed relevant literature on costs of VNS therapy in patients with DRE from the last 18 years.

RESULTS

Resource utilization and epilepsy-related events were reduced during the follow-up period compared to the baseline. Average total cost was estimated at EUR 7703.59 in year 1 and at EUR 7108.38 in year 2 following VNS implantation. Average direct costs of VNS treatment of patients with DRE over the last 18 years varied between the countries and ranged from EUR 24 790.43 in the United States to EUR 64.84 in the United Kingdom.

CONCLUSION

Vagus nerve stimulator is a cost-effective therapy yielding measurable clinical and therapeutic outcomes over the long term. Moreover, the analysis contained in this review highlights the poor consensus of methodological approaches.

Self-Management education for adults with poorly controlled epILEpsy [SMILE (UK)]: a randomised controlled trial

BACKGROUND

Epilepsy is a common neurological condition resulting in recurrent seizures. Research evidence in long-term conditions suggests that patients benefit from self-management education and that this may improve quality of life (QoL). Epilepsy self-management education has yet to be tested in a UK setting.

OBJECTIVES

To determine the effectiveness and cost-effectiveness of Self-Management education for people with poorly controlled epILEpsy [SMILE (UK)].

DESIGN

A parallel pragmatic randomised controlled trial.

SETTING

Participants were recruited from eight hospitals in London and south-east England.

PARTICIPANTS

Adults aged ≥ 16 years with epilepsy and two or more epileptic seizures in the past year, who were currently being prescribed antiepileptic drugs.

INTERVENTION

A 2-day group self-management course alongside treatment as usual (TAU). The control group received TAU.

MAIN OUTCOME MEASURES

The primary outcome is QoL in people with epilepsy at 12-month follow-up using the Quality Of Life In Epilepsy 31-P (QOLIE-31-P) scale. Other outcomes were seizure control, impact of epilepsy, medication adverse effects, psychological distress, perceived stigma, self-mastery and medication adherence. Cost-effectiveness analyses and a process evaluation were undertaken.

RANDOMISATION

A 1 : 1 ratio between trial arms using fixed block sizes of two.

BLINDING

Participants were not blinded to their group allocation because of the nature of the study. Researchers involved in data collection and analysis remained blinded throughout.

RESULTS

The trial completed successfully. A total of 404 participants were enrolled in the study [SMILE (UK), n = 205; TAU, n = 199] with 331 completing the final follow-up at 12 months [SMILE (UK), n = 163; TAU, n = 168]. In the intervention group, 61.5% completed all sessions of the course. No adverse events were found to be related to the intervention. At baseline, participants had a mean age of 41.7 years [standard deviation (SD) 14.1 years], and had epilepsy for a median of 18 years. The mean QOLIE-31-P score for the whole group at baseline was 66.0 out of 100.0 (SD 14.2). Clinically relevant levels of anxiety symptoms were reported in 53.6% of the group and depression symptoms in 28.0%. The results following an intention-to-treat analysis showed no change in any measures at the 12-month follow-up [QOLIE-31-P: SMILE (UK) mean: 67.4, SD 13.5; TAU mean: 69.5, SD 14.8]. The cost-effectiveness study showed that SMILE (UK) was possibly cost-effective but was also associated with lower QoL. The process evaluation with 20 participants revealed that a group course increased confidence by sharing with others and improved self-management behaviours.

CONCLUSIONS

For people with epilepsy and persistent seizures, a 2-day self-management education course is cost-saving, but does not improve QoL after 12-months or reduce anxiety or depression symptoms. A psychological intervention may help with anxiety and depression. Interviewed participants reported attending a group course increased their confidence and helped them improve their self-management.

FUTURE WORK

More research is needed on self-management courses, with psychological components and integration with routine monitoring.

Trends in resource utilization and prescription of anticonvulsants for patients with active epilepsy in Germany from 2003 to 2013 - A ten-year overview

This study evaluated trends in resource use and prescription patterns in patients with active epilepsy over a 10-year period at the same outpatient clinic of a German epilepsy center. We analyzed a cross-sectional patient sample of consecutive adults with active epilepsy over a 3-month period in 2013 and compared them with equally acquired data from the years 2003 and 2008. Using validated patient questionnaires, data on socioeconomic status, course of epilepsy, as well as direct and indirect costs were recorded. A total of 198 patients (mean age: 39.6±15.0years, 49.5% male) were enrolled and compared with our previous assessments in 2003 (n=101) and 2008 (n=151). In the 2013 cohort, 75.8% of the patients had focal epilepsy, and the majority were taking antiepileptic drugs (AEDs) (39.9% monotherapy, 59.1% polytherapy). We calculated epilepsy-specific costs of €3674 per three months per patient. Direct medical costs were mainly due to anticonvulsants (20.9% of total direct costs) and to hospitalization (20.8% of total direct costs). The proportion of enzyme-inducing anticonvulsants and 'old' AEDs decreased between 2003 and 2013. Indirect costs of €1795 in 2013 were mainly due to early retirement (55.0% of total indirect costs), unemployment (26.5%), and days off due to seizures (18.2%). In contrast to our previous findings from 2003 and 2008, our data show a stagnating cost increase with slightly reduced total costs and balanced direct and indirect costs in patients with active epilepsy. These findings are accompanied by an ongoing cost-neutral increase in the prescription of 'newer' and non-enzyme-inducing AEDs. However, the number and distribution of indirect cost components remained unchanged.

The Burden of Severely Drug-Refractory Epilepsy: A Comparative Longitudinal Evaluation of Mortality, Morbidity, Resource Use, and Cost Using German Health Insurance Data

Purpose

To evaluate long-term outcome of three years and treatment patterns of patients suffering from severely drug-refractory epilepsy (SDRE).

Methods

This analysis was population-based and retrospective, with data collected from four million individuals insured by statutory German health insurance. ICD-10 codes for epilepsy (G40*) and intake of anticonvulsants were used to identify prevalent cases, which were then compared with a matched cohort drawn from the population at large. Insurance data were available from 2008 to 2013. Any patient who had been prescribed with at least four different antiepileptic drugs (AEDs) in an 18-month period was defined as an SDRE case.

Results

A total of 769 patients with SDRE were identified. Of these, 19% were children and adolescents; the overall mean age was 42.3 years, 45.4% were female and 54.6% male. An average of 2.7 AEDs per patient was prescribed during the first follow-up year. The AEDs most commonly prescribed were: levetiracetam (53.5%), lamotrigine (41.4%), valproate (41.3%), lacosamide (20.4%), and topiramate (17.8%). During 3-year follow-up, there was an annual rate of hospitalization in the range 42.7 to 55%, which was significantly higher than the 11.6–12.8% (p < 0.001) for the matched controls. Admissions to hospital because of epilepsy ranged between 1.7 and 1.9 per year, with an average duration for each epilepsy-caused hospitalization of 10–11.1 days. The number of comorbidities for SDRE patients was significantly increased compared with the matched controls: depression (28% against 10%), vascular disorders (22% against 5%), and injury rates were also higher (head 16% against 3%, trunk and limbs 16% against 8%). The 3-year mortality rate for SDRE patients was 14% against 2.1% in the matched cohort.

Conclusion

SDRE patients are treated with AED polytherapy for all of the 3-year follow-up period. They are hospitalized more frequently than the general population and show increased morbidity levels and a sevenfold increase in mortality rate over 3 years. Further examination is required of ways in which new approaches to treatment could lead to better outcomes in severely affected patients.

Socioeconomic Outcome and Quality of Life in Adults after Status Epilepticus: A Multicenter, Longitudinal, Matched Case-Control Analysis from Germany

Background

There is a lack of data concerning socioeconomic outcome and quality of life (QoL) in patients after status epilepticus (SE) in Germany.

Patients and methods

Adult patients treated between 2011 and 2015 due to SE at the university hospitals in Frankfurt, Greifswald, and Marburg were asked to fill out a questionnaire regarding long-term outcome of at least 3 months after discharge. The SE cohort consisted of 25.9% patients with an acute symptomatic, 42% with a remote symptomatic and previous epilepsy, 22.2% with a new-onset remote symptomatic, and 9.9% with other or unknown etiology. A matched case–control analysis was applied for comparison with patients with drug refractory epilepsy and seizure remission, both not previously affected by SE.

Results

A total of 81 patients (mean age: 58.7 ± 18.0 years; 58% female) participated. A non-refractory course was present in 59.3%, while 27.2% had a refractory SE (RSE) and 13.6% had a superrefractory SE (SRSE). Before admission, a favorable modified Rankin Scale (mRS) of 0–3 was found in 82.7% (67/81), deteriorating to 38.3% (31/81) (p = 0.003) at discharge. The majority returned home [51.9% (42/81)], 32.1% entered a rehabilitation facility, while 12.3% were transferred to a nursing home and 3.7% to another hospital. The overall mRS at follow-up did not change; 61.8% (45/74) reached an mRS of 0–3. In RSE and SRSE, the proportion with a favorable mRS increased from 45.5% at discharge to 70% at follow-up, while QoL was comparable to a non-refractory SE course. Matched epilepsy controls in seizure remission were treated with a lower mean number of anticonvulsants (1.3 ± 0.7) compared to controls with drug refractory epilepsy (1.9 ± 0.8; p < 0.001) or SE (1.9 ± 1.1; p < 0.001). A major depression was found in 32.8% of patients with SE and in 36.8% of drug refractory epilepsy, but only in 20.3% of patients in seizure remission. QoL was reduced in all categories (QOLIE-31) in SE patients in comparison with patients in seizure remission, but was comparable to patients with drug refractory epilepsy.

Discussion

Patients after SE show substantial impairments in their QoL and daily life activities. However, in the long term, patients with RSE and SRSE had a relatively favorable outcome comparable to that of patients with a non-refractory SE course. This underlines the need for efficient therapeutic options in SE.

Understanding the burden of focal epilepsy as a function of seizure frequency in the United States, Europe, and Brazil

Objective

To understand the current burden of focal epilepsy (FE) as a function of seizure frequency.

Methods

Patients were identified from the United States (2011, 2012, and 2013), five European countries (EU; France, Germany, Italy, Spain, United Kingdom) (2011 and 2013), and Brazil (2011 and 2012) National Health and Wellness Survey (NHWS), a nationally representative, Internet‐based survey of adults (18+ years). The NHWS collected data on respondents’ quality of life (QoL), health utilities, productivity loss, and healthcare resource utilization. Indirect and direct costs were calculated from the literature. Altogether, 345 of 176,093 (U.S.A.), 73 of 30,000 (United Kingdom), 53 of 30,001 (Germany), 53 of 30,000 (France), 41 of 12,011 (Spain), 37 of 17,500 (Italy), and 71 of 24,000 (Brazil) respondents self‐reported a diagnosis of FE.

Results

Many respondents (U.S.A.: 56.2%; 5EU: 41.6%; Brazil + 5EU: 40.5%) reported persistent seizures (≥1 per year). Over 60% to just over 71% of respondents with FE were treated with antiepileptic drugs (AEDs). In the United States, seizure frequency was associated with hospitalizations, indirect costs (ages 18–60), and total direct costs. For the 5EU and Brazil + 5EU, seizure frequency was associated with physical QoL, health utilities, activity impairment, and emergency room (ER) visits. Additional associations were observed for the 5EU on hospitalizations, indirect costs (ages 18–60), ER visit costs, and total direct costs and for Brazil + 5EU on absenteeism, overall work impairment, and provider visits. Costing was not performed for Brazil + 5EU.

Significance

Around half of the patients had persistent seizures despite most taking an AED in this 2011–2013 dataset. The results support the hypothesis that reducing seizures can improve productivity and reduce resource utilization and associated costs. Regional differences may reflect differences in healthcare systems and selected patient populations. Overall, the results suggest that additional treatment options are needed to improve seizure control and reduce related costs.

The direct costs of epilepsy in Russia. A prospective cost-of-illness study from a single center in Moscow

OBJECTIVE

The objective of this study was to investigate prospectively the direct costs of epilepsy in Russia, taking a patient perspective and a bottom-up approach.

METHODS

The study was conducted in adolescents and adults with epilepsy seen in the ambulatory services of a city hospital in Moscow. Patients were assigned to different prognostic categories: newly diagnosed epilepsy; epilepsy in remission for 2+years; epilepsy in remission for <2years or with occasional seizures; active, nondrug-resistant epilepsy; drug-resistant epilepsy; and drug-resistant epilepsy in surgical candidates. Patients were followed prospectively for 12months. Demographic and clinical features at admission were collected and correlated with costs. Cost estimates were based on the Russian National Health Service perspective and its implementation in Moscow. Cost items included drugs and laboratory/instrumental tests. The costs per patient were calculated for the entire sample and for each prognostic category separately. Univariate and multivariate analyses were performed.

RESULTS

Included were 738 patients (393 men, 345 women aged 14-85years). The median annual cost/patient was €955 (IQR 521-2134; range 51-10,904). The median cost of drugs was €643 (IQR 288-1866; range 0-9960), and the median cost of laboratory/instrumental testing was €202 (IQR 160-270; range 20-1217). Mean costs varied across prognostic categories ranging from €782 in newly diagnosed patients to €3777 in patients with drug-resistant epilepsy. Mean (SD) hospital costs ranged from €646.7 (109.0) in patients with occasional seizures to €950.0 (28.3) in surgical candidates. Independent predictors of total costs were younger age at diagnosis, disability status, generalized seizures, multiple seizure types, seizure severity, and etiology.

SIGNIFICANCE

The cost of epilepsy in Moscow varies significantly depending on disease characteristics and response to drug treatment.

Neurologist adherence to clinical practice guidelines and costs in patients with newly diagnosed and chronic epilepsy in Germany

PURPOSE

The aim of this study was to evaluate physician adherence to the German Neurological Society guidelines of 2008 regarding initial monotherapy and to determine the cost-of-illness in epilepsy.

METHODS

This was an observational cohort study using health data routinely collected at 55 outpatient neurology practices throughout Germany (NeuroTransData network). Data on socioeconomic status, course of epilepsy, anticonvulsive treatment, and direct and indirect costs were recorded using practice software-based questionnaires.

RESULTS

One thousand five hundred eighty-four patients with epilepsy (785 male (49.6%); mean age: 51.3±18.1years) were enrolled, of whom 507 were newly diagnosed. Initial monotherapy was started according to authorization status in 85.9%, with nonenzyme-inducing drugs in 94.3% of all AEDs. Drugs of first choice by guideline recommendations were used in 66.5%. Total annual direct costs in the first year amounted to €2194 (SD: €4273; range: €55-43,896) per patient, with hospitalization (59% of total direct costs) and anticonvulsants (30%) as the main cost factors. Annual total direct costs decreased by 29% to €1572 in the second year, mainly because of a 59% decrease in hospitalization costs. The use of first choice AEDs did not influence costs. Chronic epilepsy was present in 1077 patients, and total annual direct costs amounted to €1847 per patient, with anticonvulsants (51.0%) and hospitalization (41.0%) as the main cost factors. Potential cost-driving factors in these patients were active epilepsy and focal epilepsy syndrome.

CONCLUSION

This study shows excellent physician adherence to guidelines regarding initial monotherapy in adults with epilepsy. Newly diagnosed patients show higher total direct and hospital costs in the first year upon diagnosis, but these are not influenced by adherence to treatment guidelines.

Welfare cost of childhood- and adolescent-onset epilepsy: A controlled national study

OBJECTIVES

Epilepsy is associated with a significant burden to patients and society. We calculated the factual excess in direct and indirect costs associated with childhood- and adolescent-onset epilepsy.

METHODS

Using records from the Danish National Patient Registry (1998-2002), we identified 3123 and 5018 patients with epilepsy aged 0-5years and 6-20years at the time of diagnosis, respectively. The two age groups of patients with epilepsy were matched to 6246 and 10,036 control persons without epilepsy, respectively, by gender, age, and geography. The controls were randomly chosen from the Danish Civil Registration System. Welfare costs included outpatient services, inpatient admissions, and emergency room visits based on the Danish National Patient Registry and information from the primary health-care sector based on data from the Danish Ministry of Health. This allowed the total health-care cost of epilepsy to be estimated. The use and costs of drugs were based on data from the Danish Medicines Agency. The frequencies of visits to outpatient clinics and hospitalizations and costs from primary sectors were based on data obtained from the National Patient Registry.

RESULTS

Children with epilepsy had higher welfare costs than controls. The highest cost was found one year after diagnosis, with higher costs up to 10years after diagnosis compared with controls. Children aged 0-5years incurred greater health-care costs than those aged 6-20years.

CONCLUSION

Epilepsy has major socioeconomic consequences for the individual person with epilepsy and for society.

[Impact of early benefit assessment on patients with epilepsy in Germany: Current healthcare provision and therapeutic needs]

Epilepsy is one of the most common chronic neurological diseases and represents a significant burden for patients, their families and society. In more than 75 % of patients anticonvulsant therapy consists of valproate, carbamazepine, lamotrigine or levetiracetam. There is a need for polytherapy in drug-refractory patients and they suffer from negative effects on quality of life and employment that is associated with high indirect costs. To allow a comprehensive treatment in this patient group, access to new anticonvulsants with novel modes of action is needed; however, all applications for new antiepileptic drugs failed to prove added benefits during the Pharmaceutical Market Restructuring Act (AMNOG) in Germany. One of the main reasons is the mandatory definition of a standard comparative therapy. It remains unclear whether there will be studies in the future which will fulfill the requirements of the current version of AMNOG. Observational studies after approval and marketing of new antiepileptic drugs could be better alternatives to prove added benefits for individual patients in the current German healthcare system.

Understanding the burden of idiopathic generalized epilepsy in the United States, Europe, and Brazil: An analysis from the National Health and Wellness Survey

The aim of this study was to understand the current burden of primary generalized tonic-clonic seizures (PGTCS) associated with idiopathic generalized epilepsy (IGE) as a function of seizure frequency. We analyzed data for (IGE) as a proxy measure of PGTCS. Little is known about the quality of life (QoL), health utility, productivity, healthcare resource utilization (HRU), and cost burden of PGTCS or IGE. Patients were identified from the US (2011, 2012, & 2013), 5EU (2011 & 2013), and Brazil (2011 & 2012) National Health and Wellness Survey, a nationally representative, internet-based survey of adults (18+ years). Patients that self-reported a diagnosis of IGE were categorized into seizure frequencies of: ≥1 seizure per week, 1-3 seizures per month, 1-4 seizures per year, or <1 seizure per year. QoL was measured using the SF-36v2 Mental (MCS) and Physical Component Summary (PCS) scores, health utilities with the SF-6D, productivity with the Work Productivity and Activity Impairment (WPAI) questionnaire, and HRU as reported in the past six months. Unit costs were estimated from the literature and multiplied against HRU values to calculate direct costs and WPAI values to calculate indirect costs. Generalized linear regression was utilized to examine the relationship between seizure frequency and each measure of burden with adjustment for covariates. Out of the general population surveyed, IGE was self-reported in 782 of 176,093 (US), 172 of 30,000 (UK), 106 of 30,001 (Germany), 87 of 30,000 (France), 31 of 12,011 (Spain), 22 of 17,500 (Italy), and 34 of 24,000 (Brazil). Persistent seizures (≥1 per year) were reported in over 40% of patients with IGE (10-15% with ≥1 seizure per week, 10-15% with 1-3 seizures per month, 20-25% with 1-4 seizures per year). Over 75% were treated with antiepileptic drugs (AEDs). Compared with those having <1 seizure per year (reference group), patients in the two most frequent seizure categories reported worse MCS and PCS scores. Patients in the three highest seizure frequency groups consistently reported worse health utility scores, and greater presenteeism (attending work while not physically or mentally capable of working), overall work impairment, activity impairment, HRU, indirect costs, and direct costs than the reference group. Despite the availability of AEDs during the year surveyed, a substantial number of patients experienced persistent seizures. Increasing seizure frequency was clearly associated with worse outcomes. The burden of PGTCS and IGE may be proportionally reduced by newer AEDs which may increase the proportion of seizure-free patients or shift more patients into lower seizure frequency categories.

Can the Direct Medical Cost of Chronic Disease Be Transferred across Different Countries? Using Cost-of-Illness Studies on Type 2 Diabetes, Epilepsy and Schizophrenia as Examples

Objectives

To systematically review cost of illness studies for schizophrenia (SC), epilepsy (EP) and type 2 diabetes mellitus (T₂DM) and explore the transferability of direct medical cost across countries.

Methods

A comprehensive literature search was performed to yield studies that estimated direct medical costs. A generalized linear model (GLM) with gamma distribution and log link was utilized to explore the variation in costs that accounted by the included factors. Both parametric (Random-effects model) and non-parametric (Boot-strapping) meta-analyses were performed to pool the converted raw cost data (expressed as percentage of GDP/capita of the country where the study was conducted).

Results

In total, 93 articles were included (40 studies were for T₂DM, 34 studies for EP and 19 studies for SC). Significant variances were detected inter- and intra-disease classes for the direct medical costs. Multivariate analysis identified that GDP/capita (p<0.05) was a significant factor contributing to the large variance in the cost results. Bootstrapping meta-analysis generated more conservative estimations with slightly wider 95% confidence intervals (CI) than the parametric meta-analysis, yielding a mean (95%CI) of 16.43% (11.32, 21.54) for T₂DM, 36.17% (22.34, 50.00) for SC and 10.49% (7.86, 13.41) for EP.

Conclusions

Converting the raw cost data into percentage of GDP/capita of individual country was demonstrated to be a feasible approach to transfer the direct medical cost across countries. The approach from our study to obtain an estimated direct cost value along with the size of specific disease population from each jurisdiction could be used for a quick check on the economic burden of particular disease for countries without such data.

Costs of epilepsy and cost-driving factors in children, adolescents, and their caregivers in Germany

OBJECTIVE

To provide first data on the cost of epilepsy and cost-driving factors in children, adolescents, and their caregivers in Germany.

METHODS

A population-based, cross-sectional sample of consecutive children and adolescents with epilepsy was evaluated in the states of Hessen and Schleswig-Holstein (total of 8.796 million inhabitants) in all health care sectors in 2011. Data on socioeconomic status, course of epilepsy, and direct and indirect costs were recorded using patient questionnaires.

RESULTS

We collected data from 489 children and adolescents (mean age ± SD 10.4 ± 4.2 years, range 0.5-17.8 years; 264 [54.0%] male) who were treated by neuropediatricians (n = 253; 51.7%), at centers for social pediatrics ("Sozialpaediatrische Zentren," n = 110, 22.5%) and epilepsy centers (n = 126; 25.8%). Total direct costs summed up to €1,619 ± €4,375 per participant and 3-month period. Direct medical costs were due mainly to hospitalization (47.8%, €774 ± €3,595 per 3 months), anticonvulsants (13.2%, €213 ± €363), and ancillary treatment (9.1%, €147 ± €344). The total indirect costs amounted to €1,231 ± €2,830 in mothers and to €83 ± €593 in fathers; 17.4% (n = 85) of mothers and 0.6% (n = 3) of fathers reduced their working hours or quit work because of their child's epilepsy. Independent cost-driving factors were younger age, symptomatic cause, and polytherapy with anticonvulsants. Older age, active epilepsy, symptomatic cause, and polytherapy were independent predictors of higher antiepileptic drug (AED) costs, whereas younger age, longer epilepsy duration, symptomatic cause, disability, and parental depression were independent predictors for higher indirect costs.

SIGNIFICANCE

Treatment of children and adolescents with epilepsy is associated with high direct costs due to frequent inpatient admissions and high indirect costs due to productivity losses in mothers. Direct costs are age-dependent and higher in patients with symptomatic epilepsy and polytherapy. Indirect costs are higher in the presence of a child's disability and parental depression.

Healthcare utilization and costs in adults with stable and uncontrolled epilepsy

Despite the availability of numerous antiepileptic drugs (AEDs), some epilepsies remain resistant to treatment. We compared utilization and costs in patients with uncontrolled epilepsy to those with stable epilepsy. Claims data (2007-2009) were used to identify adults with epilepsy requiring additional AED therapy (having uncontrolled epilepsy) and those not requiring additional AED therapy (having stable epilepsy). The date in 2008 on which an additional AED was started was the index date for patients with uncontrolled epilepsy, and a randomly selected date was used for patients with stable epilepsy, whose AED use was unchanged in the preceding year. In the postindex year, all pharmacy and medical claims were used to estimate overall utilization and costs; claims with epilepsy in any diagnosis field were used to estimate epilepsy-related outcomes. Outcomes were adjusted using multivariate analyses. We identified 1536 patients with uncontrolled epilepsy and 8571 patients with stable epilepsy (mean age: 42.8years; female: 48%). Patients with uncontrolled epilepsy had higher comorbidity rates (p<.02). A greater proportion of patients with uncontrolled epilepsy had ≥1 hospitalization or emergency department visit (p<.001). Patients with uncontrolled epilepsy had a greater mean length of hospital stay and more physician office visits (p<.034). After adjustment, the odds of hospitalization (OR: 1.8, any diagnosis; 2.2, epilepsy-related) and emergency department visit (OR: 1.6, any diagnosis; 1.9, epilepsy-related) were greater for patients with uncontrolled epilepsy. Annual overall ($23,238 vs. $13,839) and epilepsy-related ($12,399 vs. $5511) costs were higher in patients with uncontrolled epilepsy and remained higher after adjustment (p<.001). Patients with uncontrolled epilepsy use more services and incur higher costs compared with those with stable epilepsy. Epilepsy-related costs accounted for <50% of the total costs, suggesting that comorbid conditions and/or underidentification of utilization may substantially contribute to costs.

Health Technology Assessment report on the presurgical evaluation and surgical treatment of drug-resistant epilepsy

PURPOSE

Epilepsy is a neurologic disorder with major social impact. Surgery is a valuable option in patients who are not responding to antiepileptic drugs. The literature reports demonstrate that a proportion ranging from 40 to 100% of patients with epilepsy achieve seizure remission after surgery. A presurgical evaluation (clinical and instrumental) must be performed in all patients with drug-resistant epilepsy to assess their suitability for surgical intervention. Health Technology Assessment (HTA) represents a modern approach to the analysis of technologies used for health care. HTA could be considered a bridge between science that produces evidence and the decisions that can be taken on the basis of that evidence at different levels of the health care system. The aim of this study is the HTA of epilepsy surgery including clinical, ethical, social, and economic features.

METHODS

The present study includes an analysis of the diagnostic and surgical workup performed at the Italian centers for the diagnosis and treatment of drug-resistant epilepsy (DRE). The study includes the following issues: (1) social, ethical impact, and costs of the disease; (2) clinical results, efficacy, and safety of surgery; (3) ethics and quality of life after surgery; and (4) economic impact and productivity regained after surgery. The cost of managing a patient with DRE included in the presurgical study was estimated by the bottom-up microcosting technique that starts from a detailed collection of data on consumption of resources and full costing. The phases analyzed were (1) noninvasive diagnostic workup; (2) neurosurgical intervention; and (3) follow-up.

KEY FINDINGS

The literature reports indicate epilepsy surgery as an effective treatment both on clinical results and on ethical, social, and quality of life aspects. The workup including the noninvasive presurgical study followed by surgery has a total cost of €20,827. Management of short-term follow-up increases the overhead to €22,291 at the first year, and then to €23,571 after 5 years. According to the estimates made in this survey, funding based on diagnosis-related group (DRG) tariff for the noninvasive diagnostic stage involving hospital admission is not remunerative in Italy either at regional or national levels. Effectively the difference between full cost and DRG has a delta of €3,402 and €2,537 respectively. The total cost of the presurgical, surgical, and follow-up evaluation is not remunerative for €10,554 (national data).

SIGNIFICANCE

Economic surveys in Italy have shown that surgery for DRE is an advantageous treatment from the standpoint of third-party payers and is cost-effective for society. DRE presurgical evaluation and surgery are not remunerative either at regional or national levels.

Krankheitskosten der Borderline Persönlichkeitsstörung aus gesellschaftlicher Perspektive

Hintergrund: Bislang liegen in Deutschland keine Befunde über die krankheitsbedingten Kosten von Patienten mit einer Borderline Persönlichkeitsstörung (BPS) aus der gesellschaftlichen Perspektive vor. Fragestellung: Wie hoch sind die jährlichen Krankheitskosten pro BPS-Patient? In welchen Bereichen entstehen die höchsten Kosten? Methodik: Auf der Grundlage aktueller gesundheitsökonomischer Empfehlungen wurden die krankheitsbedingten Kosten von N = 55 BPS-Patienten in Berlin für den Zeitraum von 12 Monaten vor Beginn einer ambulanten Psychotherapie aus der gesellschaftlichen Perspektive mit einem Interview erhoben und berechnet. Ergebnisse: Die Krankheitskosten in den 12 Monaten vor der Therapie betrugen insgesamt € 26.882 (SD = € 32.275) pro BPS-Patient. € 17.976 (SD = € 23.867) davon waren direkte Kosten, € 8.906 (SD = € 15.518) wurden für indirekte Kosten berechnet. Die höchsten Kosten entstanden durch stationäre und teilstationäre Aufenthalte (M = € 13.121; SD = € 19.808) sowie durch krankheitsbedingte Erwerbsunfähigkeit (M = € 7.020; SD = € 15.099). Schlussfolgerungen: Die BPS geht mit hohen gesellschaftlichen Kosten einher, die weitaus höher sind als die durch viele andere psychische und somatische Erkrankungen bedingten Kosten.

Cost of epilepsy in children attending a tertiary centre in Nigeria

Epilepsy is one of the leading paediatric neurological disorders in Nigeria and many other parts of the world. There is very little documented on the economic costs of epilepsy in Nigeria and other countries in sub-Saharan Africa. This study was carried out to estimate the total cost of childhood epilepsy in a cohort of Nigerian children and therefore provide essential information on the economic burden of childhood epilepsy in Nigeria. A cost of illness study was performed on a cohort of 215 consecutive cases of epilepsy seen and treated at the University College Hospital, Ibadan, Nigeria. Data on demographics, clinical characteristics, utilization of resources and costs were collected. The total annual cost of epilepsy ranged from Nigerian naira (N)23 200 (US$155) to N3 298 500 (US$21,900) with a median of N107 600 (US$717) per patient per year. Direct medical and non-medical costs accounted for 71.8% of the total mean annual cost of epilepsy. Anti-epileptic drug therapy and in-patient care accounted for 21.8% and 33.0% of the mean total annual cost respectively and more than half of the families expended over 20% of their total family income on the care of the child with epilepsy. The economic burden of childhood epilepsy in Nigeria is enormous with very high out-of-pocket expenses.

Counseling and social work for persons with epilepsy: observational study on demand and issues in Hessen, Germany

The goal of the social management of epilepsy is to decrease the physical, psychological, and social consequences for persons with epilepsy (PWEs). The objective of this observational study was to determine the needs and issues of PWEs in the utilization of epilepsy counseling services between 2008 and 2012 in the German state of Hessen. Sociodemographic data, employment status, counseling issues, and characteristics were collected at first and follow-up visits. An average of 492 (272 males, 55.3%) PWEs presented at counseling services per year. These were mainly children or adolescents below the age of 20years (22.4%) and PWEs in working age between 20 and 65years (73.6%). The majority of PWEs seeking counseling were employed (44.4%, annual average: 219 PWEs, SD: 39). However, a substantial part (114/219, 52.1%) of these employed PWEs reported problems or difficulties at their workplace associated with the diagnosis of epilepsy. We could identify four major issues addressed by the PWEs as 1) diagnosis of epilepsy, 2) employment, 3) family-related matters, and 4) social or medical aids linked with public authorities. This study demonstrated the continuous demand for epilepsy counseling with at least one out of twenty (5.8%) PWEs in need of counseling per year. Further studies are warranted to answer questions on outcome and long-term course. Epilepsy counseling should be available to all PWEs on a national level and may be helpful in preventing long-term unemployment and early retirement while maintaining quality of care for PWEs.

Inpatient treatment costs of status epilepticus in adults in Germany

PURPOSE

Status epilepticus (SE) is an important neurological emergency and a significant source of direct costs related to hospitalization; however, no cost-of-illness (COI) studies have been performed in Europe. The objective of this study was to determine and characterize hospital costs related to the acute inpatient treatment of SE and to provide national estimates of SE hospitalization costs.

METHODS

Adult inpatient treatment costs related to SE and costs attributable to epilepsy-related hospital admissions were derived from billing data of participating hospitals.

RESULTS

During the 4-month study period a total of 96 patients (59.5 ± 21.6 years; 52 male) received inpatient treatment for epilepsy-related reasons, 10 of these (10.4%) were treated for SE. Epilepsy was newly diagnosed in 30/96 patients (31.3%), of whom five presented with SE. The admission costs related to SE (€8347 ± 10,773 per patient per admission) were significantly higher than those related to admissions of patients with newly diagnosed (€1998 ± 1089; p = 0.014) or established epilepsy (€3475 ± 4413; p = 0.026). Of the total inpatient costs (€346,319) 24.4% were attributable to SE, 14.4% to newly diagnosed epilepsy without SE (n = 25) and 61.2% to complications of established epilepsy (n = 61). Extrapolation to the whole of Germany (population 82 million) indicates that SE causes hospital costs of more than €83 million per year while the total of epilepsy-related inpatient treatment costs amounts to €342 million.

CONCLUSION

Acute treatment of SE is responsible for a high proportion of hospital costs associated with epilepsy. With a high incidence of SE in the elderly population, the health care systems will face an increasing number of presentations with SE and its associated costs, underlining the necessity to further evaluate the burden and optimize the treatment of SE.

Trends in resource utilization and prescription of anticonvulsants for patients with active epilepsy in Germany

This study evaluated trends in the resource use of patients with active epilepsy over a 5-year period at an outpatient clinic of a German epilepsy center. Two cross-sectional cohorts of consecutive adults with active epilepsy were evaluated over a 3-month period in 2003 and 2008. Data on socioeconomic status, course of epilepsy, as well as direct and indirect costs were recorded using validated patient questionnaires. We enrolled 101 patients in 2003 and 151 patients in 2008. In both cohorts, 76% of the patients suffered from focal epilepsy, and the majority was on antiepileptic drug (AED) polytherapy (mean AED number: 1.7 (2003), 1.8 (2008)). We calculated epilepsy-specific costs of € 2955 in 2003 and € 3532 in 2008 per 3 months per patient. Direct medical costs were mainly due to anticonvulsants in 2003 (59.4% of total direct costs, 34.0% in 2008) and to hospitalization in 2008 (46.9% of total direct costs, 27.7% in 2003). The proportion of enzyme-inducing anticonvulsants and 'old' AEDs decreased between 2003 and 2008. Indirect costs of € 1689 and € 1847 were mainly due to early retirement (48.4%; 46.0% of total indirect costs in 2003; 2008), unemployment (26.1%; 24.2%), and days off due to seizures (25.5%; 29.8%). This study showed a shift in distribution of direct cost components with increased hospital costs as well as a cost-neutral increase in the prescription of 'newer' AEDs. The amount and distribution of indirect cost components remained unchanged.
