Stroke rehabilitation pathways during the first year: A cost-effectiveness analysis from a cohort of 460 individuals.

BACKGROUND: Stroke burden challenges global health, and social and economic policies. Although stroke recovery encompasses a wide range of care, including in-hospital, outpatient, and community-based rehabilitation, there are no published cost-effectiveness studies of integrated post-stroke pathways. OBJECTIVE: To determine the most cost-effective rehabilitation pathway during the first 12 months after a first-ever stroke. METHODS: A cohort of people in the acute phase of a first stroke was followed after hospital discharge; 51 % women, mean (SD) age 74.4 (12.9) years, mean National Institute of Health Stroke Scale score 11.7 (8.5) points, and mode modified Rankin Scale score 3 points. We developed a decision tree model of 9 sequences of rehabilitation care organised in 3 stages (3, 6 and 12 months) through a combination of public, semi-public and private entities, considering both the individual and healthcare service perspectives. Health outcomes were expressed as quality-adjusted life years (QALY) over a 1-year time horizon. Costs included healthcare, social care, and productivity losses. Sensitivity analyses were conducted on model input values. RESULTS: From the individual perspective, pathway 3 (Short-term Inpatient Unit ¼ Community Clinic) was the most cost-effective, followed by pathway 1 (Rehabilitation Centre ¼ Community Clinic). From the healthcare service perspective, pathway 3 was the most cost-effective followed by pathway 7 (Outpatient Hospital ¼ Private Clinic). All other pathways were considered strongly dominated and excluded from the analysis. The total 1-year mean cost ranged between €12104 and €23024 from the individual's perspective and between €10992 and €31319 from the healthcare service perspective. CONCLUSION: Assuming a willingness-to-pay threshold of one times the national gross domestic product (€20633/QALY), pathway 3 (Short-term Inpatient Unit ¼ Community Clinic) was the most cost-effective strategy from both the individual and healthcare service perspectives. Rehabilitation pathway data contribute to the development of a future integrated care system adapted to different stroke profiles.

From healthcare system to individuals through stroke rehabilitation pathways.Outcomes, information, and satisfaction along 12 months prospective cohort in Portugal.

BACKGROUND: The nature and quality of stroke survivor rehabilitation varies throughout Europe, including in Portugal, having not been widely monitored or benchmarked. OBJECTIVES: This study analyses the stroke care pathway from three perspectives: healthcare system, process, and patient. METHODS: The study uses data from a one-year single-center prospective cohort of first stroke patients, assessed at baseline, 3, 6, and 12 months. Care pathways and settings were described in terms of organizational model, funding, patient involvement, frequency and intensity and multidisciplinary team. Patient-level information and satisfaction were evaluated using a 10-point numeric rating scale. Kruskal - Wallis and post-hoc tests were used to compare EQ-5D-3 L, National Institute of Health Stroke Scale (NIHSS), Modified Rankin Scale (mRS), Barthel Index, Mini-Mental State Examination scores between pathways and settings. RESULTS: A total of 391 acute stroke patients, with a mean disability of 3.7 (mRS) and severity of 11.7 (NIHSS) participated. Six pathways and eight settings were described. A lack of compliance between guidelines and care was identified. There were significant differences in the four outcomes between the six pathways (p-values 0.007 to 0.020) suggesting inefficiency and inequalities, with an inadequate level of information and patient satisfaction. After post-hoc analysis, pathways 1 and 2 showed highest outcomes (p-values 0.001 to 0.002). Within settings, short-term units showed high scores, followed by rehabilitation center, outpatient hospital, and community clinic (p-values 0.001 to 0.040). CONCLUSION: A multilevel characterization of the post-stroke rehabilitation pathway showed a more complete perspective on stroke management which may contribute to future rehabilitation and stroke policies.

Healthcare, Clinical Factors and Rehabilitation Predicting Quality of Life in First-time Stroke Patients: A 12-month Longitudinal Study.

OBJECTIVES: One of the long-term rehabilitation goals in stroke survivors is to achieve the best health-related quality of life (HRQoL). This study analyzes the evolution of HRQoL one-year post-stroke to establish the main pre-stroke, clinical, health care and rehabilitation predictors. MATERIALS AND METHODS: This study uses patient-level data from a one-year single-center prospective cohort study of first stroke patients, assessed at baseline, 3, 6 and 12 months. A generalized linear model with a linear response determined independent predictors of HRQol with EQ-5D-3L and SF-6D. The model included age, gender, scholarity, monthly income, residence, occupation, National Institute of Health Stroke Scale (NIHSS), Modified Rankin Scale (mRS), Barthel Index (BI), Mini-Mental State Examination (MMSE), length of stay, door-to-neurological examination time, access, frequency, and satisfaction with rehabilitation care. RESULTS: A total of 391 acute stroke patients, with a mean disability of 3.7 and severity of 11.7 participated. A decline of HRQoL was observed from baseline to the first three months in both indexes, with an increase in HRQoL at 3 months until 12 months. Scores were significantly lower compared to corresponding population norms throughout follow-up, mostly affected by stroke severity, disability, rehabilitation access and frequency. Higher HRQoL was associated with lower mRS, NIHSS, age, length of stay, and with higher BI, MMSE, scholarity, occupation, and rehabilitation care. CONCLUSION: Clinical measures and rehabilitation care were the strongest HRQoL predictors of stroke survivors regardless of severity levels. These findings may contribute to the development of future health policies that focus on post-stroke recovery.

EQ-5D Portuguese population norms.

OBJECTIVES: The EQ-5D is a widely used preference-based measure. Normative data can be used as references to analyze the effects of healthcare, determine the burden of disease and enable regional or country comparisons. Population norms for the EQ-5D exist for other countries but have not been previously published for Portugal. The purpose of this study was to derive EQ-5D Portuguese population norms. METHODS: The EQ-5D was applied by phone interview to a random sample of the Portuguese general population (n = 1,500) stratified by age, gender and region. The Portuguese value set was used to derive the EQ-5D index. RESULTS: Mean values were computed by gender and age groups, marital status, educational attainment, region and other variables to obtain the EQ-5D Portuguese norms. Health status declines with advancing age, and women reported worse health status than men. These results are similar to other EQ-5D population health studies. CONCLUSION: This study provides Portuguese population health-related quality of life data measured by the EQ-5D that can be used as population norms. These norms can be used to inform Portuguese policy makers, health care professionals and researchers in issues related to health care policy and planning and quantification of treatment effects on health status.

[Contribution for the validation of the Portuguese version of EQ-5D]. / Contributos para a Validação da Versão Portuguesa do EQ-5D.

INTRODUCTION: The EQ-5D allows the achievement of two essential components of any measure of health-related quality of life to be used in cost-utility economic evaluations: (i) a profile describing the health status in terms of domains or dimensions; and (ii) a numeric value associated with the health status described. AIM: The Portuguese version of the EQ-5D questionnaire was completed in 1998, based on guidelines set by the EuroQol Group, including translation and back translation procedures. Despite its wide use in Portugal, until now it had not yet been published studies that initially led to the Portuguese version and the guarantee of acceptability, reliability and validity. The purpose of this article is to document these first values relating to the Portuguese version of the EQ-5D. MATERIAL AND METHODS: We used three different samples: a first one with 1,500 individuals representative of the Portuguese population; a second with 140 individuals just intended for the reliability test; and a third sample with 643 individual patients with cataracts, asthma, chronic obstructive pulmonary disease, or rheumatoid arthritis. RESULTS: The acceptability was assessed by the number of missing responses. It was also found a marked ceiling effect, with a large part of the sample not reporting any problems in the dimensions of the EQ-5D. DISCUSSION: The construct validity was tested by examining the degree to which low values of EQ-5D were positively associated with increasing age, being female, and the sick, as well as the values of dimensions of the SF-36v2 scale. Convergent validity was based on correlations between EQ-5D values and other specific measures. The EQ-5D showed moderate to high correlations with other disease-specific measures of health status and health related quality of life. CONCLUSION: We can state that the Portuguese version of the EQ-5D has a good accessibility, reliability and validity in measuring health.

Introdução: O EQ-5D permite a junção de duas componentes essenciais de qualquer medida de qualidade de vida relacionada com a saúde a ser usada em avaliações económicas de custo-utilidade: (i) um perfil descrevendo o estado de saúde em termos de domínios ou dimensões; e (ii) um valor numérico associado ao estado de saúde anteriormente descrito.Objectivo: A versão portuguesa do questionário EQ-5D foi finalizada em 1998, com base em normas de orientação definidas pelo Grupo EuroQol, incluindo os procedimentos de tradução e retroversão. Apesar da sua larga utilização em Portugal, até agora ainda não tinham sido publicados os estudos que conduziram inicialmente à versão portuguesa e à garantia de aceitabilidade, fiabilidade e validade. O propósito do presente artigo é, assim, documentar estes primeiros valores referentes à versão portuguesa do EQ-5D.Material e Métodos: Foram utilizadas três amostras diferentes: uma primeira com 1.500 indivíduos representativa da populaçãoportuguesa; uma segunda com 140 indivíduos apenas destinada ao teste da fiabilidade; e uma terceira amostra com 643 indivíduos doentes com cataratas, asma, doença pulmonar obstrutiva crónica ou artrite reumatoide.Resultados: A aceitabilidade foi avaliada pelo número de respostas em falta. Foi também encontrado um marcado efeito de teto com grande parte da amostra a não reportar quaisquer problemas nas dimensões do EQ-5D.Discussão: A validade de construção foi testada pela análise do grau com que valores baixos de EQ-5D estavam positivamente associados ao aumento da idade, ao ser do sexo feminino, e ao estar doente, assim como a valores de dimensões da escala SF-36v2. A validade convergente foi baseada nas correlações entre valores do EQ-5D e outras escalas específicas de condição de saúde. O EQ-5D apresentou correlações moderadas a altas com outras medidas de estado de saúde e de qualidade de vida relacionada com a saúde, específicas de cada doença.Conclusão: A versão portuguesa do EQ-5D tem uma boa aceitabilidade, fiabilidade e validade na medição do estado de saúde.

Quality of life in asthma patients.

In this paper we present a study whose main aim is the measurement of the Health Related Quality of Life (HRQoL) of patients with asthma and the presentation of a first draft of normative values as measured by the SF-6D for asthma patients. In addition, we investigate how far non-disease-specific HRQoL measures can distinguish groups in terms of sociodemographic characteristics. The Portuguese versions of the EQ-5D, SF-6D, AQLQ(S) and ACQ were administered using personal interviews to a representative sample of the Portuguese population with asthma. Most of the individuals did not report significant problems in the dimensions used, with the exception of the physical functioning, where individuals reported moderate limitations. The mean utility value was 0.86. Male gender, young, single, individuals with high educational attainment level, employed, individuals with high income and those residing in urban areas reported higher utility levels. As expected, those who were in a severe stadium of the disease reported lower mean utility levels than those who were in a less severe stadium of the disease. Normative values for the SF-6D were computed for patients with asthma by gender, age, marital status, educational attainment level, employment status, area of residence and average monthly net income. The preference-based measures used in this study distinguish patient groups with asthma in terms of socio- demographic groups. The normative values can be used in economic evaluation and clinical studies as they incorporate patients' preferences and translate the value attributed to patients' health state.

[Health-related quality of life in patients with rheumatoid arthritis]. / Qualidade de vida em doentes com Artrite Reumatóide.

OBJECTIVES: Rheumatoid arthritis RA is a chronic rheumatic disease of unknown aetiology and greater incidence among the elderly. It can lead to serious consequences regarding functional limitations and patient's ability to work. The purpose of this study was to assess the health-related quality of life in patients with RA. METHODS: Portuguese version of SF-6D and Portuguese translations of EQ-5D and AIMS2-SF were self-administered in a postal survey to a representative sample of the Portuguese population with RA. Data concerning the patients' characteristics and the stage of the disease were also collected. RESULTS: The majority of the patients presented minor problems in some of the instruments dimensions. In a scale from 0.30 to 1.00 the average utility score was 0.77. The lowest utility scores were reported by women those who were divorced or separated individuals with lower educational levels who had lower incomes, were recently diagnosed and those who were not taking new biological therapies. Apart from these, patients who had a more severe RA and co-morbidity also report lower utility scores. CONCLUSIONS: The preference-based utility measures used in this study adequately discriminate across different RA severity and socio-demographic background. Assuming that these values represent the patients' preferences and the utility associated with their health state, the results presented in this paper may be used as an approximation to normative values for the SF-6D in economic evaluation studies as well as in clinical studies.

An application of the SF-6D to create heath values in Portuguese working age adults.

OBJECTIVES: This study describes the health-related quality of life (HRQOL) of the Portuguese working age population and investigates sociodemographic differences. METHODS: Subjects randomly selected from the working age population (n=2,459) were assessed using the SF-36v2 and converted into the preference-based SF-6D. RESULTS: The mean SF-6D utility value was 0.70 (range 0.63-0.73). The mean utility value was lower for the lower educational level than for the highest. Women, people living in rural areas and older adults reported lower levels of utility values. Non-parametric tests showed that health utility values were significantly related to employment; unskilled manual workers reported utility values lower than non-manual workers. For different diseases, mean utility values ranged from 0.58 (sexual diseases) to 0.66 (hepatic conditions). Cluster analysis was adopted to classify individuals into three groups according to their answers to the SF-6D dimensions. Multinomial logit regression was used to detect sociodemographic characteristics affecting the probability of following each cluster pattern. This study yielded normative data by age and gender for the SF-6D. CONCLUSIONS: The authors conclude that SF-6D is an effective tool for measuring HRQOL in the community so that different population groups can be compared. The preference-based measure used seems to discriminate adequately across sociodemographic differences. These results allow a better understanding of the impact of sociodemographic variables on the burden of illness perception.
