Quality of life and chronic disease in patients receiving primary health care

Problem Statement: Chronic disease entails physical, psychological and social issues with a decrease in the quality of life. The assessment of QoL has been applied as indicator in patients with chronic diseases. Research Questions: What is the quality of life in patients with chronic disease? What are the socio-demographic variables that influence the quality of life in patients? Purpose: To assess the quality of life in patients suffering from chronic disease and identify socio-demographic variables which influence the quality of life of patients suffering from chronic disease. Research Methods: We conducted a cross-sectional analytical study using a sample composed of 228 users (134 females) from a Family Health Unit in the municipality of Viseu. Data collection was made by means of a questionnaire, consisting of sociodemographic variables, the SF-12 scale and the existence of chronic disease was assessed through the questions – “Do you currently suffer from any chronic disease?”; “If so, which one(s)?”. Findings: The most common chronic diseases were hypertension (59.9%). Female patients with a chronic disease reported worse physical functioning, role-physical and role-emotional; increased bodily pain and better quality of life regarding general health. Male patients showed worse role-physical, increased bodily pain and vitality. Sociodemographic variables which were associated with quality of life were area of residence, academic qualifications and work situation. Conclusion: Chronic disease affects quality of life negatively. Quality of life in both patients groups was associated with socio-demographic variables. Health-related quality of life is an essential issue and should be considered as a priority in health policies.

Satisfaction of users of primary health care with nursing care : sample of the central region of Portugal

Introdução: A satisfação dos doentes constitui um indicador indispensável para a avaliação da qualidade dos cuidados e há evidência da sua correlação com os resultados em saúde. A satisfação com os cuidados de saúde é um conceito multidimensional que considera aspetos como acesso, organização e interação doente - profissional. Consideramos que os cuidados de enfermagem, em particular, são fundamentais no processo saúde/doença. Objetivos: Validar uma escala para avaliar a satisfação dos utentes face aos cuidados de enfermagem, adaptado do instrumento EUROPEP e avaliar a satisfação dos utentes dos cuidados de saúde primários da região centro de Portugal. Material e métodos: Estudo transversal, com uma amostra de 827 utentes adultos (maioria do sexo feminino 64,4%) com uma média de idade de 50,08±18,58 anos. Os dados foram recolhidos através de um questionário, constituído por variáveis sociodemográficas, o instrumento EUROPEP (Ferreira, 1995) para avaliar a satisfação com os cuidados de saúde primários e para avaliar a satisfação especificamente com a equipa de enfermagem elaboramos questões adaptadas do instrumento EUROPEP e agrupadas nas dimensões relação de ajuda, dimensão interpessoal e instrumental. A consistência interna, reprodutibilidade e análise de conteúdo foram avaliados com recurso ao SPSS 23.0; considerando a consistência aceitável para um de Cronbach > 0,70. O coeficiente para cada item é apresentado com um intervalo de confiança de 95%. Resultados: Em todas as dimensões do questionário EUROPEP, a maior percentagem de satisfação com os cuidados situou-se entre “boa” e “muito boa”. As dimensões criadas para avaliar especificamente os cuidados de enfermagem apresentaram um coeficiente de α de Cronbach total de 0,972. Conclusões: Estes resultados sugerem que as dimensões criadas para avaliar os cuidados de enfermagem serão úteis para a investigação na população Portuguesa. A satisfação do utente é decisiva para a qualidade e eficiência dos cuidados prestados, sendo necessário o compromisso de todos os prestadores na implementação de práticas sistemáticas de gestão que conduzam à satisfação, dando particular atenção à melhoria contínua dos processos organizacionais.

Do health care providers use online patient ratings to improve the quality of care?

Background: Physician-rating websites have become a popular tool to create more transparency about the quality of health care providers. So far, it remains unknown whether online-based rating websites have the potential to contribute to a better standard of care. Objective: Our goal was to examine which health care providers use online rating websites and for what purposes, and whether health care providers use online patient ratings to improve patient care. Methods: We conducted an online-based cross-sectional study by surveying 2360 physicians and other health care providers (September 2015). In addition to descriptive statistics, we performed multilevel logistic regression models to ascertain the effects of providers' demographics as well as report card-related variables on the likelihood that providers implement measures to improve patient care. Results: Overall, more than half of the responding providers surveyed (54.66%, 1290/2360) used online ratings to derive measures to improve patient care (implemented measures: mean 3.06, SD 2.29). Ophthalmologists (68%, 40/59) and gynecologists (65.4%, 123/188) were most likely to implement any measures. The most widely implemented quality measures were related to communication with patients (28.77%, 679/2360), the appointment scheduling process (23.60%, 557/2360), and office workflow (21.23%, 501/2360). Scaled-survey results had a greater impact on deriving measures than narrative comments. Multilevel logistic regression models revealed medical specialty, the frequency of report card use, and the appraisal of the trustworthiness of scaled-survey ratings to be significantly associated predictors for implementing measures to improve patient care because of online ratings. Conclusions: Our results suggest that online ratings displayed on physician-rating websites have an impact on patient care. Despite the limitations of our study and unintended consequences of physician-rating websites, they still may have the potential to improve patient care.

Data protection by design in the e-health care sector: theoretical and applied perspectives

In the digital age, e-health technologies play a pivotal role in the processing of medical information. As personal health data represents sensitive information concerning a data subject, enhancing data protection and security of systems and practices has become a primary concern. In recent years, there has been an increasing interest in the concept of Privacy by Design, which aims at developing a product or a service in a way that it supports privacy principles and rules. In the EU, Article 25 of the General Data Protection Regulation provides a binding obligation of implementing Data Protection by Design technical and organisational measures. This thesis explores how an e-health system could be developed and how data processing activities could be carried out to apply data protection principles and requirements from the design stage. The research attempts to bridge the gap between the legal and technical disciplines on DPbD by providing a set of guidelines for the implementation of the principle. The work is based on literature review, legal and comparative analysis, and investigation of the existing technical solutions and engineering methodologies. The work can be differentiated by theoretical and applied perspectives. First, it critically conducts a legal analysis on the principle of PbD and it studies the DPbD legal obligation and the related provisions. Later, the research contextualises the rule in the health care field by investigating the applicable legal framework for personal health data processing. Moreover, the research focuses on the US legal system by conducting a comparative analysis. Adopting an applied perspective, the research investigates the existing technical methodologies and tools to design data protection and it proposes a set of comprehensive DPbD organisational and technical guidelines for a crucial case study, that is an Electronic Health Record system.

Oxigenoterapia domiciliar prolongada em crianças e adolescentes: uma análise do uso clínico e de custos de um programa assistencial

OBJETIVOS: Descrever as características clínicas e laboratoriais dos pacientes em oxigenoterapia domiciliar prolongada acompanhados pelo programa de atendimento domiciliar do Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo, durante um período de 8 anos, e comparar os grupos com e sem hipertensão pulmonar secundária. Estimar o custo do programa utilizando concentradores versus cilindros de oxigênio arcados pela instituição. MÉTODOS: Estudo descritivo retrospectivo e de coorte dos pacientes em oxigenoterapia domiciliar prolongada, em seguimento no período de 2002 a 2009, na Unidade de Pneumologia do Instituto da Criança do Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo. RESULTADOS: Foram estudados 165 pacientes, 53% do sexo masculino, com as medianas: idade de início da oxigenoterapia - 3,6 anos; tempo de oxigenoterapia - 7 anos; e tempo de sobrevida após início da oxigenoterapia - 3,4 anos. Os principais diagnósticos foram: fibrose cística (22%), displasia broncopulmonar (19%) e bronquiolite obliterante (15%). Dos 33 pacientes que realizaram espirometria, 70% apresentavam distúrbio ventilatório obstrutivo grave. O exame ecocardiográfico foi executado em 134 pacientes; 51% deles tinham hipertensão pulmonar secundária. Houve associação estatisticamente significante entre: presença de hipertensão pulmonar e necessidade de maiores fluxos de oxigênio (qui-quadrado, p = 0,011); e presença de hipertensão pulmonar e maior tempo de oxigenoterapia (Logrank, p = 0,0001). Não houve diferença estatisticamente significante entre tempo de sobrevida após início da oxigenoterapia e presença de hipertensão pulmonar. Os custos médios mensais do programa foram: US$ 7.392,93 para os concentradores e US$ 16.630,92 para cilindros. CONCLUSÕES: A oxigenoterapia domiciliar prolongada foi empregada em distintas doenças crônicas, predominantemente em lactentes e pré-escolares. Houve alta frequência de hipertensão pulmonar associada a maiores períodos de uso e fluxos de oxigênio, sem associação à sobrevida. A substituição dos cilindros por concentradores poderá reduzir custos significativamente.

Telehealth and the diagnosis and management of cardiac disease

The financial and personal burden of chronic cardiac disease is high. Costs are likely to increase over the next few decades. Promising applications of telehealth have appeared in the diagnosis and management of cardiac disease and there are indications that telehealth services can improve the management of chronic cardiac disease as well as extend services to remote and rural populations. Telehealth has been applied to the capture of symptoms of cardiac disease with electrocardiography and echocardiography, to the management and rehabilitation of recently discharged patients, and in peer-to-peer consultation where remote expertise can facilitate diagnosis. Telehealth promises cost reductions in service delivery, although there is a need for properly controlled cost-effectiveness trials to underpin telehealth with a firm evidence base.

Cost of malaria control in China: Henan's consolidation programme from community and government perspectives

Objective To assist with strategic planning for the eradication,of malaria in Henan Province, China, which reached the consolidation phase of malaria control in 1992, when only 318 malaria cases were reported, Methods We conducted a prospective two-year study of the costs for Henan's malaria control programme. We used a cost model that could also be applied to other malaria programmes in-mainland China, and analysed the cost of the three components of Henan's malaria programme. suspected malaria case management,, vector surveillance,,and population blood surveys. Primary cost data were collected from the government, and data on suspected malaria patient's were collected in two malaria counties (population 2 093 100). We enlisted the help of 260 village doctors. in six-townships or former communities (population 247 762), and studied all 12 315 reported cases of suspected malaria in catchment areas in 1994 and 1995. Findings The average-annual government investment in malaria control was estimated to be US$ 111 516 (case-management 59%; active blood surveys 25%;vector surveillance 12%; and contingencies and special projects 4%). The average cost (direct and indirect) for-patients seeking-treatment for suspected malaria was US$ 3.48, equivalent,to 10 days' income for rural residents. Each suspected malaria case cost the government an, average of US$ 0.78. Conclusion Further cuts in government funding will increase future costs, when epidemic malaria returns; investment in malaria control should therefore continue at least at current levels,of US$ 0.03 per person a risk.

Cost of diseases in Brazil: breast cancer, enteritis, cardiac valve disease and bronchopneumonia

The results from the need to develop methodologies for performing cost analysis in developing countries, principally in the region of Latin America, were studied. It, furthermore, serves to generate knowledge from an economic evaluation in order to support decision-making related to the organization of health systems, particularly in the efficient use of resources which are allocated for the provision of medical services. Two chronic diseases (breast cancer and cardiac valve disease) and two infections (enteritis and bronchopneumonia) were selected for the study. The results recommend the use of a valid methodology for economic cost analysis of any disease to be studied and the use of this information in the decision-making process.

Economic burden of expected epidemiological changes in diseases related to tobacco, Mexico

OBJECTIVE: To determine health care costs and economic burden of epidemiological changes in diseases related to tobacco consumption. METHODS: A time-series analysis in Mexico (1994-2005) was carried out on seven health interventions: chronic obstructive pulmonary diseases, lung cancer with and without surgical intervention, asthma in smokers and non-smokers, full treatment course with nicotine gum, and full treatment course with nicotine patch. According with Box-Jenkins methodology, probabilistic models were developed to forecast the expected changes in the epidemiologic profile and the expected changes in health care services required for selected interventions. Health care costs were estimated following the instrumentation methods and validated with consensus technique. RESULTS: A comparison of the economic impact in 2006 vs. 2008 showed 20-90% increase in expected cases depending on the disease (p<0.05), and 25-93% increase in financial requirements (p<0.01). The study data suggest that changes in the demand for health services for patients with respiratory diseases related to tobacco consumption will continue showing an increasing trend. CONCLUSIONS: In economic terms, the growing number of cases expected during the study period indicates a process of internal competition and adds an element of intrinsic competition in the management of preventive and curative interventions. The study results support the assumption that if preventive programs remain unchanged, the increasing demands for curative health care may cause great financial and management challenges to the health care system of middle-income countries like Mexico.

A literacia em saúde: investimento na promoção da saúde e na racionalização de custos

A Organização Mundial da Saúde define a literacia em saúde como o conjunto de competências cognitivas e sociais e a capacidade dos indivíduos para compreenderem e usarem informação para a promoção e manutenção da saúde. A transmissão de informação sobre saúde é mais eficaz quando os seus conteúdos são especificamente desenhados para uma pessoa ou para um grupo populacional e quando a mensagem é bem delimitada, realçando os benefícios (ganhos) e os custos (perdas) associados aos comportamentos e às tomadas de decisão. Analisa-se, neste estudo, o conceito de literacia em saúde e a associação da baixa literacia em saúde aos comportamentos em saúde e aos gastos em saúde. Apresenta-se uma análise da literatura científica publicada sobre a baixa literacia em saúde e a sua implicação nos custos na saúde usando, para este objectivo, uma base de dados das ciências da saúde (MEDLINE/PubMed) e quatro plataformas científicas (DOAJ, SCOPUS, SciELO e Web of Science). A literatura científica analisada evidencia que pessoas com baixa literacia em saúde apresentam uma menor capacidade de compreensão dos conteúdos de material informativo sobre alimentos, doenças crónicas ou sobre o uso de medicamentos, por exemplo, bem como maior dificuldade em pesquisar, seleccionar, ler e assimilar a informação em saúde disponível na Internet. A baixa literacia em saúde relaciona-se, então. com a dificuldade na prevenção e na gestão de problemas de saúde, bem como com comportamentos ineficazes de saúde, i.e., com o uso inadequado de medicamentos, com o recurso excessivo aos serviços de saúde (em especial, os de urgências) ou com a ineficácia em lidar com situações de emergência. A baixa literacia está também associada a taxas de hospitalização mais altas, mas também mais longas no tempo (o que implica mais custos associados a internamento prolongado, mais exames de diagnóstico e fraca adesão à terapêutica medicamentosa), a uma diminuição da utilização de medidas preventivas e a uma fraca adesão à prescrição terapêutica. A baixa literacia acaba por afectar igualmente a comunicação (e a relação) médico-doente. Apresentam-se, como complemento, sugestões de melhoria da literacia em saúde e da comunicação médico-doente para efeitos da promoção da saúde.

Non invasive ventilation during exercise in COPD patients: a systematic review with meta-analysis

COPD is a major cause of morbidity and mortality worldwide, representing a major public health problem due to the high health and economic resource consumption. Pulmonary rehabilitation is a standard care recommendation for these patients, in order to control the symptoms and optimize the functional capacity, reducing health care costs associated with exacerbations and activity limitations and participation. However, in patients with severe COPD exercise performance can be difficult, due to extreme dyspnea, decreased muscle strength and fatigue. In addition, hypoxemia and dyspnea during efforts and daily activities may occur, limiting their quality of life. Thus, NIV have been used as adjunct to exercise, in order to improve exercise capacity in these patients. However, there is no consensus for this technique recommendation. Our objective was to verify whether the use of NIV during exercise is effective than exercise without NIV in dyspnea, walked distance, blood gases and health status in COPD patients, through a systematic review and meta-analysis.

Budget impact from the incorporation of positron emission tomography – computed tomography for staging lung cancers

OBJECTIVE To estimate the budget impact from the incorporation of positron emission tomography (PET) in mediastinal and distant staging of non-small cell lung cancer.METHODS The estimates were calculated by the epidemiological method for years 2014 to 2018. Nation-wide data were used about the incidence; data on distribution of the disease´s prevalence and on the technologies’ accuracy were from the literature; data regarding involved costs were taken from a micro-costing study and from Brazilian Unified Health System (SUS) database. Two strategies for using PET were analyzed: the offer to all newly-diagnosed patients, and the restricted offer to the ones who had negative results in previous computed tomography (CT) exams. Univariate and extreme scenarios sensitivity analyses were conducted to evaluate the influence from sources of uncertainties in the parameters used.RESULTS The incorporation of PET-CT in SUS would imply the need for additional resources of 158.1 BRL (98.2 USD) million for the restricted offer and 202.7 BRL (125.9 USD) million for the inclusive offer in five years, with a difference of 44.6 BRL (27.7 USD) million between the two offer strategies within that period. In absolute terms, the total budget impact from its incorporation in SUS, in five years, would be 555 BRL (345 USD) and 600 BRL (372.8 USD) million, respectively. The costs from the PET-CT procedure were the most influential parameter in the results. In the most optimistic scenario, the additional budget impact would be reduced to 86.9 BRL (54 USD) and 103.8 BRL (64.5 USD) million, considering PET-CT for negative CT and PET-CT for all, respectively.CONCLUSIONS The incorporation of PET in the clinical staging of non-small cell lung cancer seems to be financially feasible considering the high budget of the Brazilian Ministry of Health. The potential reduction in the number of unnecessary surgeries may cause the available resources to be more efficiently allocated.

Strategies for price reduction of HIV medicines under a monopoly situation in Brazil

ABSTRACT OBJECTIVE To analyze Government strategies for reducing prices of antiretroviral medicines for HIV in Brazil. METHODS Analysis of Ministry of Health purchases of antiretroviral medicines, from 2005 to 2013. Expenditures and costs of the treatment per year were analyzed and compared to international prices of atazanavir. Price reductions were estimated based on the terms of a voluntary license of patent rights and technology transfer in the Partnership for Productive Development Agreement for atazanavir. RESULTS Atazanavir, a patented medicine, represented a significant share of the expenditures on antiretrovirals purchased from the private sector. Prices in Brazil were higher than international references, and no evidence was found of a relationship between purchase volume and price paid by the Ministry of Health. Concerning the latest strategy to reduce prices, involving local production of the 200 mg capsule, the price reduction was greater than the estimated reduction. As for the 300 mg capsule, the amounts paid in the first two years after the Partnership for Productive Development Agreement were close to the estimated values. Prices in nominal values for both dosage forms remained virtually constant between 2011 (the signature of the Partnership for Productive Development Agreement), 2012 and 2013 (after the establishment of the Partnership). CONCLUSIONS Price reduction of medicines is complex in limited-competition environments. The use of a Partnership for Productive Development Agreement as a strategy to increase the capacity of local production and to reduce prices raises issues regarding its effectiveness in reducing prices and to overcome patent barriers. Investments in research and development that can stimulate technological accumulation should be considered by the Government to strengthen its bargaining power to negotiate medicines prices under a monopoly situation.
