Does the inclusion of societal costs change the economic evaluations recommendations? A systematic review for multiple sclerosis disease.

BACKGROUND: Multiple sclerosis imposes a heavy burden on the person who suffers from it and on the relatives, due to the caregiving load involved. The objective was to analyse whether the inclusion of social costs in economic evaluations of multiple sclerosis-related interventions changed results and/or conclusions. METHODS: A systematic review was launched using Medline and the Cost-Effectiveness Analysis Registry of Tufts University (2000-2019). Included studies should: (1) be an original study published in a scientific journal, (2) be an economic evaluation of any multiple sclerosis-related intervention, (3) include productivity losses and/or informal care costs (social costs), (4) be written in English, (5) use quality-adjusted life years as outcome, and (6) separate the results according to the perspective applied. RESULTS: Twenty-nine articles were selected, resulting in 67 economic evaluation estimations. Social costs were included in 47% of the studies. Productivity losses were assessed in 90% of the estimations (the human capital approach was the most frequently used method), whereas informal care costs were included in nearly two-thirds of the estimations (applying the opportunity and the replacement-cost methods equally). The inclusion of social costs modified the figures for incremental costs in 15 estimations, leading to a change in the conclusions in 10 estimations, 6 of them changing from not recommended from the healthcare perspective to implemented from the societal perspective. The inclusion of social costs also altered the results from cost-effective to dominant in five additional estimations. CONCLUSIONS: The inclusion of social costs affected the results/conclusions in multiple sclerosis-related interventions, helping to identify the most appropriate interventions for reducing its economic burden from a broader perspective.

Economic burden and health-related quality of life in tenosynovial giant-cell tumour patients in Europe: an observational disease registry.

BACKGROUND: Tenosynovial Giant-Cell Tumour (TGCT) is a benign clonal neoplastic proliferation arising from the synovium, causing a variety of symptoms and often requiring repetitive surgery. This study aims to define the economic burden-from a societal perspective-associated with TGCT patients and their health-related quality of life (HRQOL) in six European countries. METHODS: This article analyses data from a multinational, multicentre, prospective observational registry, the TGCT Observational Platform Project (TOPP), involving hospitals and tertiary sarcoma centres from six European countries (Austria, France, Germany, Italy, the Netherlands, and Spain). It includes information on TGCT patients' health-related quality of life and healthcare and non-healthcare resources used at baseline (the 12-month period prior to the patients entering the registry) and after 12 months of follow-up. RESULTS: 146 TGCT patients enrolled for the study, of which 137 fulfilled the inclusion criteria. Their mean age was 44.5 years, and 62% were female. The annual average total costs associated with TGCT were €4866 at baseline and €5160 at the 12-month follow-up visit. The annual average healthcare costs associated with TGCT were €4620 at baseline, of which 67% and 18% corresponded to surgery and medical visits, respectively. At the 12-month follow-up, the mean healthcare costs amounted to €5094, with surgery representing 70% of total costs. Loss of productivity represented, on average, 5% of the total cost at baseline and 1.3% at follow-up. The most-affected HRQOL dimensions, measured with the EQ-5D-5L instrument, were pain or discomfort, mobility, and the performance of usual activities, both at baseline and at the follow-up visit. Regarding HRQOL, patients declared a mean index score of 0.75 at baseline and 0.76 at the 12-month follow-up. CONCLUSION: The results suggest that TGCT places a heavy burden on its sufferers, which increases after one year of follow-up, mainly due to the healthcare resources required-in particular, surgical procedures. As a result, this condition has a high economic impact on healthcare budgets, while the HRQOL of TGCT patients substantially deteriorates over time.

How relevant are social costs in economic evaluations? The case of Alzheimer's disease.

BACKGROUND: The main objective of this study was to analyse how the inclusion (exclusion) of social costs can alter the results and conclusions of economic evaluations in the field of Alzheimer's disease interventions. METHODS: We designed a systematic review that included economic evaluations in Alzheimer's disease. The search strategy was launched in 2000 and ran until November 2018. The inclusion criteria were: being an original study published in a scientific journal, being an economic evaluation of any intervention related to Alzheimer's disease, including social costs (informal care costs and/or productivity losses), being written in English, using QALYs as an outcome for the incremental cost-utility analysis, and separating the results according to the perspective applied. RESULTS: It was finally included 27 studies and 55 economic evaluations. Around 11% of economic evaluations changed their main conclusions. More precisely, three of them concluded that the new intervention became cost-effective when the societal perspective was considered, whereas when using just the health care payer perspective, the new intervention did not result in a cost-utility ratio below the threshold considered. Nevertheless, the inclusion of social cost can also influence the results, as 37% of the economic evaluations included became the dominant strategy after including social costs when they were already cost-effective in the health care perspective. CONCLUSIONS: Social costs can substantially modify the results of the economic evaluations. Therefore, taking into account social costs in diseases such as Alzheimer's can be a key element in making decisions about public financing and pricing of health interventions.

Using a stated preference discrete choice experiment to assess societal value from the perspective of decision-makers in Europe. Does it work for rare diseases?

OBJECTIVES: To pilot the feasibility of using a discrete choice experiment (DCE) design to investigate individual preferences from the decision-maker perspective regarding the use of public funding for orphan drugs and generate prior information for future experimental designs. METHODS: A DCE was used on a convenience sample of participants from five European countries (England, France, Germany, Italy and Spain), exploring their preferences in distinct healthcare scenarios involving orphan drugs. A preliminary review of the empirical literature on distributive preferences informed the selection of attributes and their levels in the design. An online questionnaire was used to conduct the DCE survey. RESULTS: A total of 199 questionnaires were completed. The five country model showed relative preference for some attributes over others: cost of treatment, improvement in health, value for money and availability of treatment alternatives received the greatest attention. However, disease severity, beginning of life, waiting times and side effects were also shown to be important social values that should not be ignored. CONCLUSIONS: The findings presented in this study provide insight about the preferences that can influence decisions on orphan drugs in different countries. This study also provides valuable prior information that could inform future DCE designs in this area.

Calidad de vida relacionada con la salud en pacientes con ataxias espinocerebelosas / Health-related quality of life in patients with spinocerebellar ataxia

Introducción. El deterioro progresivo de los pacientes con ataxias espinocerebelosas (AEC) genera un gran impacto sobre su calidad de vida relacionada con la salud (CVRS). En este estudio se evalúa la CVRS en una muestra de pacientes diagnosticados de AEC y se pretende estimar la capacidad predictiva de un conjunto de variables sociodemográficas en las distintas dimensiones que conforman el cuestionario. Métodos. Se evaluó a un total de 80 pacientes diagnosticados de AEC, a través de un cuestionario sociodemográfico y del cuestionario genérico de salud SF-36. Se estudiaron variables sociodemográficas como sexo, edad, existencia de cuidador, situación laboral y tiempo desde el diagnóstico de la enfermedad. Resultados. Las dimensiones que componen el SF-36 muestran correlaciones positivas y significativas entre ellas. Las puntuaciones medias obtenidas en cada una de las dimensiones difieren según el sexo, siendo significativa la diferencia solo en la dimensión salud general, con media más alta en los hombres. En relación con la edad, se encuentran diferencias significativas en las dimensiones vitalidad y función social, con puntuaciones mayores en el rango de menor edad (menores de 34 años). La variable que explica la mayor parte de la varianza del cuestionario es la existencia de cuidador. Conclusiones. El Cuestionario de Salud SF-36 es un instrumento válido y fiable para medir la CVRS en pacientes con diagnóstico de AEC. Asimismo, la variable existencia de cuidador parece determinar la calidad de vida autopercibida por estos pacientes (AU)

Introduction. The progressive deterioration of patients with spinocerebellar ataxia (SCA) has a major impact on their health-related quality of life (HRQOL). This study evaluates HRQOL in a sample of patients diagnosed with SCA and aims to estimate the predictive ability of a set of sociodemographic variables for the different dimensions of the General Health Questionnaire. Methods. A total of 80 patients diagnosed with SCA were assessed using a sociodemographic questionnaire and the SF-36 General Health Questionnaire. The sociodemographic variables studied were sex, age, presence of a carer, employment status, and time elapsed from diagnosis of the disease. Results. The 8 subscales of the SF-36 show positive and significant correlations to one another. Mean scores obtained on each SF-36 subscale differ between women and men, although this difference is significant only on the general health subscale, with men scoring higher than women. We found significant age differences on the vitality and social function subscales, with higher scores among younger patients (< 34 years). The variable ‘presence of a carer’ accounts for most of the total variance of the questionnaire. Conclusions. The SF-36 is a valid and useful instrument for evaluating HRQOL in patients diagnosed with SCA. Presence of a carer seems to be a determinant of self-perceived quality of life in these patients (AU)

Social/economic costs and health-related quality of life in patients with juvenile idiopathic arthritis in Europe.

OBJECTIVE: The aim of this study was to determine the economic burden from a societal perspective and the health-related quality of life (HRQOL) of patients with juvenile idiopathic arthritis (JIA) in Europe. METHODS: We conducted a cross-sectional study of patients with JIA from Germany, Italy, Spain, France, the United Kingdom, Bulgaria, and Sweden. Data on demographic characteristics, healthcare resource utilization, informal care, labor productivity losses, and HRQOL were collected from the questionnaires completed by patients or their caregivers. HRQOL was measured with the EuroQol 5-domain (EQ-5D-5L) questionnaire. RESULTS: A total of 162 patients (67 Germany, 34 Sweden, 33 Italy, 23 United Kingdom, 4 France, and 1 Bulgaria) completed the questionnaire. Excluding Bulgarian results, due to small sample size, country-specific annual health care costs ranged from €18,913 to €36,396 (reference year: 2012). Estimated direct healthcare costs ranged from €11,068 to €22,138; direct non-healthcare costs ranged from €7837 to €14,155 and labor productivity losses ranged from €0 to €8715. Costs are also shown to differ between children and adults. The mean EQ-5D index score for JIA patients was estimated at between 0.44 and 0.88, and the mean EQ-5D visual analogue scale score was estimated at between 62 and 79. CONCLUSIONS: JIA patients incur considerable societal costs and experience substantial deterioration in HRQOL in some countries. Compared with previous studies, our results show a remarkable increase in annual healthcare costs for JIA patients. Reasons for the increase are the inclusion of non-professional caregiver costs, a wider use of biologics, and longer hospital stays.

Economic evaluation in chronic pain: a systematic review and de novo flexible economic model.

There is unmet need in patients suffering from chronic pain, yet innovation may be impeded by the difficulty of justifying economic value in a field beset by data limitations and methodological variability. A systematic review was conducted to identify and summarise the key areas of variability and limitations in modelling approaches in the economic evaluation of treatments for chronic pain. The results of the literature review were then used to support the development of a fully flexible open-source economic model structure, designed to test structural and data assumptions and act as a reference for future modelling practice. The key model design themes identified from the systematic review included: time horizon; titration and stabilisation; number of treatment lines; choice/ordering of treatment; and the impact of parameter uncertainty (given reliance on expert opinion). Exploratory analyses using the model to compare a hypothetical novel therapy versus morphine as first-line treatments showed cost-effectiveness results to be sensitive to structural and data assumptions. Assumptions about the treatment pathway and choice of time horizon were key model drivers. Our results suggest structural model design and data assumptions may have driven previous cost-effectiveness results and ultimately decisions based on economic value. We therefore conclude that it is vital that future economic models in chronic pain are designed to be fully transparent and hope our open-source code is useful in order to aspire to a common approach to modelling pain that includes robust sensitivity analyses to test structural and parameter uncertainty.

Calidad de vida relacionada con la salud en pacientes con esclerosis lateral amiotrófica / Quality of life related to health in patients with amyotrophic lateral sclerosis

Introducción: El deterioro progresivo de los pacientes con esclerosis lateral amiotrófica (ELA) genera un gran impacto sobre su calidad de vida relacionada con la salud (CVRS). En este estudio se evalúa la CVRS en una muestra de pacientes diagnosticados de ELA y se pretende estimar la capacidad predictiva de un conjunto de variables sociodemográficas en las distintas dimensiones que conforman el cuestionario. Métodos: Se evaluó a un total de 63 pacientes diagnosticados de ELA, a través de un cuestionario sociodemográfico y del cuestionario genérico de salud SF-36. Se estudiaron variables sociodemográficas como sexo, edad, existencia de cuidador, situación laboral y tiempo desde el diagnóstico de la enfermedad. Resultados: El cuestionario SF-36 muestra una correlación positiva entre las diferentes dimensiones que la componen lo que demuestra su confiabilidad. Las puntuaciones medias obtenidas en cada una de las dimensiones del SF-36 son mayores en hombres que en mujeres, aunque esta diferencia es significativa solo en la dimensión Rol físico, siendo el grupo de pacientes de menor edad (menos de 56 años) quienes presentan puntuaciones medias más altas en la mayoría de las dimensiones del SF-36. La mayor parte de la variancia de la prueba queda explicada por la variable existencia de cuidador. Conclusiones: Se confirma la capacidad del SF-36 como medida válida y fiable de la CVRS para pacientes con un diagnóstico de ELA, que discrimina entre pacientes con diferentes estados de salud según su nivel de dependencia

Introduction: Progressive deterioration in patients with amyotrophic lateral sclerosis (ALS) has a major impact on their health-related quality of life (HRQOL). The objectives of this study are to evaluate HRQOL in a sample of patients diagnosed with ALS and estimate the predictive capability of a set of sociodemographic variables for the different scales covered by a general health survey. Methods: A total of 63 patients diagnosed with ALS were assessed using a sociodemographic questionnaire and the SF-36 general health survey. The sociodemographic variables studied were sex, age, presence of a caregiver, employment status, and time from diagnosis of disease. Results: The SF-36 survey shows positive correlations between the different scales composing it, which proves its reliability. The mean scores obtained for each of the SF-36 scales were higher in men than in women, although the only statistically significant difference was for the Physical Role scale. The lowest age range (less than 56 years) presented the highest mean scores for most of these dimensions. Most of the variance in the test is explained by the variable 'presence of caregiver'. Conclusions: The SF-36 health survey has been confirmed as a valid and useful tool for evaluating HRQOL in ALS patients, and it discriminates between patients in different states of health according to their level of dependency

The societal costs of intracerebral hemorrhage in Spain.

This study estimates the lifetime societal costs associated with incident intracerebral hemorrhage (ICH) in Spain. An epidemiological model of ICH incidence, survival and morbidity was developed using retrospective data from 28 hospitals in Andalusia and published data identified in a systematic literature review. Data on resource utilization and costs were obtained from five hospitals in the Canary Islands, whereas cost of outpatient care, informal care and lost productivity were obtained from standardized questionnaires completed by survivors of ICH. The lifetime societal costs of incident ICH in Spain is estimated at 46,193 euros per patient. Direct medical costs accounted for 32.7% of lifetime costs, whilst 67.3% were related to indirect costs. One-third of direct medical costs over the first year were attributable to follow-up care, including rehabilitation. Indirect costs were dominated by costs of informal care (71.2%). The aggregated lifetime societal costs for the estimated 12,534 Spanish patients with a first-ever ICH in 2004 was 579 million euros. ICH implies substantial costs to society primarily due to formal and informal follow-up care and support needed after hospital discharge. Interventions that offer survival benefits without improving patients' functional status are likely to further increase the societal costs of ICH.

Sensitivity and specificity of digital retinal imaging for screening diabetic retinopathy.

AIMS: To assess the effectiveness of a non-mydriatic digital camera (45 degrees -30 degrees photographs) compared with the reference method for screening diabetic retinopathy. METHODS: Type 1 and 2 diabetic patients (n = 773; 1546 eyes) underwent screening for diabetic retinopathy in a prospective observational study. Hospital-based non-mydriatic digital retinal imaging by a consultant specialist in retinal diseases was compared with slit-lamp biomicroscopy and indirect ophthalmoscopy through dilated pupils, as a gold standard, previously performed in a community health centre by another consultant specialist in retinal diseases. The main outcome measures were sensitivity and specificity of screening methods and prevalence of diabetic retinopathy. RESULTS: The prevalence of any form of diabetic retinopathy was 42.4% (n = 328); the prevalence of sight-threatening including macular oedema and proliferative retinopathy was 9.6% (n = 74). Sensitivity of detection of any diabetic retinopathy by digital imaging was 92% (95% confidence interval 90, 94). Specificity of detection of any diabetic retinopathy was 96% (95, 98). The predictive value of the negative tests was 94% and of a positive test 95%. For sight-threatening retinopathy digital imaging had a sensitivity of 100%. CONCLUSIONS: A high sensitivity and specificity are essential for an effective screening programme. These results confirm digital retinal imaging with a non-mydriatic camera as an effective option in community-based screening programmes for diabetic retinopathy.

Impact on health-related quality of life and perceived burden of informal caregivers of individuals with Alzheimer's disease.

This study assessed the impact on health-related quality of life (HRQL) and the perceived burden of informal caregivers of individuals with Alzheimer's disease (AD) on the Canary Islands (Spain). We utilized a multicenter, cross-sectional design, based on questionnaire responses of 237 informal caregivers of AD patients. Patients were classified according to the degree of severity utilizing the Clinical Dementia Rating Scale. Sociodemographic, HRQL (EQ-5D) and functional dependency data were gathered together with the degree of caregiver burden. Caregivers had a higher frequency of problems than did the general population for every EQ-5D dimension. Caregivers' HRQL was inversely associated with the subject dependency level and caregiver age. HRQL was higher for more educated caregivers. Variables with a negative and/or significant effect on caregivers' HRQL were high feelings of burden, more committed time to care, and older age. The caregiver burden quantified by the Zarit scale showed 83.3% of caregivers with a high level of burden.

[Routine preoperative screening of asymptomatic patients: beliefs and attitudes of anesthesiologists in the Canary Islands, Spain]. / Pruebas preoperatorias rutinarias en población asintomática: opiniones y actitudes de los profesionales en Canarias.

OBJECTIVES: To identify factors that explain anesthesiologists' inappropriate use of preoperative tests in asymptomatic patients scheduled for elective surgery. MATERIAL AND METHODS: A validated questionnaire was sent to anesthesiologists at university hospitals in the Canary Islands. Information about preoperative testing patterns and reasons for selecting tests was gathered. RESULTS: The questionnaire was self-administered by 66 anesthesiologists (68% of the total). Scientific knowledge was not the reason why most respondents ordered preoperative tests in asymptomatic individuals. That was the opinion of 95% of anesthesiologists for chest x-rays, 82% for electrocardiograms, and 68% for laboratory tests. Clinical history and a medical examination gave sufficient information for selecting patients in need of specific tests in the opinion of 77.19% of the respondents. Half did not agree that routine electrocardiograms and laboratory tests should be abandoned. The justification for these tests was coverage of medical malpractice liability for 68.42%. Most considered that the need to order preoperative tests in asymptomatic patients increased after age 40. CONCLUSIONS: Although anesthesiologists admit that their request for preoperative tests in asymptomatic individuals is not supported by scientific evidence, the quest for safety and legal protection from the consequences of potential adverse consequences of providing anesthesia affects the selection of preoperative tests for asymptomatic patients.

OBJETIVO: Identificar algunas razones que contribuyen a explicar el uso inapropiado, por parte de los anestesiólogos, de las pruebas preoperatorias en población asintomática que va a ser sometida a cirugía electiva. MATERIAL Y MÉTODO: Un cuestionario validado fue enviado a los anestesiólogos de los hospitales universitarios de Canarias. Se recogió información sobre el patrón de uso y sobre las razones que justifican la selección de pruebas preoperatorias. RESULTADOS: El cuestionario fue autocumplimentado por 66 anestesiólogos (68% del total). Para la mayoría, el conocimiento científico disponible no avala la realización de pruebas preoperatorias en personas asintomáticas. Ésta era la opinión del 95% de los anestesiólogos para la radiografía de tórax; del 82% para el ECG y del 68% para las pruebas de laboratorio. Para el 77,19% de los participantes, la historia clínica y el examen médico suministran suficiente información para seleccionar los pacientes que precisen pruebas específicas. El 50% no está de acuerdo en abandonar la solicitud rutinaria del ECG y de las pruebas de laboratorio. Para el 68,42%, la solicitud de estas pruebas se justifica para cubrir la responsabilidad médico/legal. La mayoría consideran que a partir de los 40 años de edad aumenta la necesidad de realizar pruebas preoperatorias en población asintomática. CONCLUSIONES: Si bien la mayoría de anestesiólogos admiten que la solicitud de pruebas preoperatorias en población asintomática no está respaldada por el conocimiento científico, la búsqueda de seguridad y protección legal frente a las consecuencias adversas potenciales del acto anestésico condiciona la toma de decisiones en la selección de pruebas preoperatorias en población asintomática

[Socio-economic costs of mental health in the Canary Islands, Spain, in 2002]. / Costes socioeconómicos de las enfermedades mentales en las Islas Canarias en 2002.

OBJECTIVE: To evaluate the economic impact in terms of direct and indirect costs of the mental health in Canary Islands (Spain) in 2002. DESIGN: The cost-of-illness method was used. Direct and indirect costs were estimated using prevalence cost, i.e., the costs produced in 2002. The human capital theory approach has been used. SETTING: Canary Islands, Spain, including primary health care and inpatient care. PARTICIPANTS: Mental health patients. MAIN MEASUREMENTS: Direct health costs (inpatients, ambulatory care, primary health care, and drugs). Indirect costs (premature death, short-term illness, and permanent disability). RESULTS: The total costs of mental health were 189.59 million euros. The direct health costs were 81.67 million euros, constituting 43% of the total costs and 5.2% of the total public health care budget in this region. The indirect costs of mental health were 107.92 million euros, representing 57% of the total costs. CONCLUSIONS: Although this study adopts a conservative approach, the high socio-economic cost of the mental health helps us to define better the dimension of the problem to establish priorities besides opening a way towards cost-effectiveness studies that allow a more transparent debate on this topic.

Bone mineral density referral for dual-energy X-ray absorptiometry using quantitative ultrasound as a prescreening tool in postmenopausal women from the general population: a cost-effectiveness analysis.

The aim of our study was to assess, from the perspective of the National Health Services in Spain, the cost-effectiveness of quantitative ultrasound (QUS) as a prescreen referral method for bone mineral density (BMD) assessment by dual-energy X-ray absorptiometry (DXA) in postmenopausal women of the general population. Using femoral neck DXA and heel QUS. We evaluated 267 consecutive postmenopausal women 65 years and older and attending primary care physician offices for any medical reason. Subjects were classified as osteoporotic or nonosteoporotic (normal or osteopenic) using the WHO definition for DXA. Effectiveness was assessed in terms of the sensitivity and specificity of the referral decisions based on the QUS measurement. Local costs were estimated from health services and actual resource used. Cost-effectiveness was evaluated in terms of the expected cost per true positive osteoporotic case detected. Baseline prevalence of osteoporosis evaluated by DXA was 55.8%. The sensitivity and specificity for the diagnosis of osteoporosis by QUS using the optimal cutoff thresholds for the estimated heel BMD T-score were 97% and 94%, respectively. The average cost per osteoporotic case detected based on DXA measurement alone was 23.85 euros. The average cost per osteoporotic case detected using QUS as a prescreen was 22.00 euros. The incremental cost-effectiveness of DXA versus QUS was 114.00 euros per true positive case detected. Our results suggest that screening for osteoporosis with QUS while applying strict cufoff values in postmenopausal women of the general population is not substantially more cost-effective than DXA alone for the diagnosis of osteoporosis. However, the screening strategy with QUS may be an option in those circumstances where the diagnosis of osteoporosis is deficient because of the difficulty in accessing DXA equipment.
