"O termo de consentimento livre e esclarecido e a pesquisa em seres humanos na área de saúde: uma revisão crítica" / The informed consent and the research in human beings within the health area : a critical review

Sérgio Slawka 05 August 2005 (has links)
Para avaliar a efetividade do processo de obtenção do termo de consentimento livre e esclarecido (TCLE) no contexto da pesquisa clínica em seres humanos, foram realizadas análises sistematizadas sobre os principais elementos de sustentação do TCLE (bioética na pesquisa em seres humanos, direitos humanos do sujeito da pesquisa, história da obtenção do TCLE, e regulamentações brasileiras na pesquisa em seres humanos), assim como também análises sistematizadas sobre a efetividade dos principais processos envolvidos na obtenção do TCLE (comunicação médico-paciente, tomada de decisão pelo sujeito da pesquisa, e interpretação das expressões de probabilidade no TCLE pelo sujeito da pesquisa). Ainda que estes três processos envolvidos na obtenção do TCLE apresentem, individualmente, alguns procedimentos efetivos, verificou-se que a obtenção de um TCLE verdadeiramente autônomo é utópica e, portanto, o processo de obtenção do TCLE é considerado não-efetivo / In order to evaluate the effectiveness of the process for obtaining the informed consent (IC) within the context of clinical research in human beings, systematic-like analysis were performed on the key elements supporting the IC (bioethics within the research in human beings, human rights for the research subject, history of the obtainment for the IC, and Brazilian regulation within research in human beings), as well as systematic-like analysis on the effectiveness of the major processes involved in the obtainment for the IC (physician-patient communication, decision-making for the research subject, and interpretation of the probability expressions in the IC by the research subject). Eventhough these three processes involved in the obtainment for the IC present, individually, a few effective procedures, the obtainment of a truly autonomous IC is utopia and thus the process for obtaining the IC is considered non-effective

Conduta leiga e assistência médica em pacientes do Pronto-Socorro de Oftalmologia do Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo / Non-medical conduct and medical assistance in patients assisted in the Ophthalmology Emergency Room at Clinics Hospital of the University of Sao Paulo School of Medicine

Regina de Souza Carvalho 15 August 2007 (has links)
Foi realizado um survey transversal, descritivo e analítico em amostra não-probabilística, prontamente acessível, de tamanho 561, formada por pacientes que procuraram o Pronto-Socorro de Oftalmologia do Hospital das Clinicas da Faculdade de Medicina da Universidade de São Paulo numa semana considerada típica de atendimento.Os dados foram obtidos através da ficha administrativa e aplicação de questionário semi-estruturado, realizado por meio de entrevistas. O questionário também constava de entrevista com o médico que fez o atendimento. O estudo teve como objetivos, em relação a usuários do pronto-socorro: descrever características sócio-demográficas, razões da procura e da escolha de unidade hospitalar, verificar conhecimentos e condutas referentes a causas e tratamentos do agravo ocular; verificar a adoção de tratamentos oculares prévios ao atendimento, identificar fontes de orientação na adoção de tratamentos, verificar causas de demora na procura de tratamento, identificar percepções sobre diagnóstico e tratamento prescrito. Em relação à instituição: determinar a proporção de atendimentos oculares de urgência e não urgência; disponibilizar informações para subsidiar intervenções educativas e assistenciais de saúde ocular. A análise estatística foi realizada com o uso do programa Stata (versão 9.0). Entre os resultados, destacou-se: o período de maior procura por atendimento oftalmológico no Pronto-Socorro do Hospital das Clínicas foi matutino e nos dias da semana; não houve diferença significante entre os sexos; a média de idade foi 39,8 anos; o atendimento foi realizado pelo Sistema Único de Saúde para 91,1% dos pacientes. A maioria dos atendidos tinha baixa renda e escolaridade. Metade dos pacientes era de fora da área de cobertura do Hospital das Clínicas. Para 49,0% a escolha do Hospital das Clínicas ocorreu por confiança e competência; para 42,2% por não haver oftalmologista nos serviços que costumam freqüentar. O tempo para procurar o serviço foi de mais de 24 horas a uma semana para 40,8% dos pacientes. A demora em procurar atendimento ocorreu por não considerar que era urgente por 47,0% e 34,1% foram a outro serviço antes. Daqueles que foram a outros serviços previamente, 48,8% não tiveram alteração do quadro, 39,6% pioraram sintomas. A automedicação foi usada prévio a vinda ao Pronto-Socorro por 40,5% dos pacientes. Desses, 29,4% usaram produtos caseiros. Os produtos mais freqüentemente utilizados foram água boricada, soro fisiológico, água de torneira ou poço, chás, compressas, lavagem com ervas (alecrim, arruda). Não foram observadas diferenças significativas no uso de automedicação para tratar os sintomas oculares entre homens e mulheres (p = 0,95), nas diferentes faixas etárias (p = 0,14) ou nos diferentes níveis de escolaridade (p = 0,21). Também não foi observada diferença no padrão de uso de automedicação quanto à situação de trabalho dos pacientes (p = 0,15) ou quanto ao seu local de residência (p = 0,52).Pacientes com diagnóstico de inflamação/infecção ou trauma apresentaram as maiores proporções de uso de automedicação (49,5%). Relataram ter procurado auxílio religioso para tratar o problema 16,1% dos pacientes. Referiram ter entendido a informação sobre o que tinham 95,1%dos pacientes. Dos que receberam prescrição de medicamento, 95,0% entenderam como e porque usá-lo. Aproximadamente 50,0% dos pacientes deram nota máxima ao atendimento recebido. Segundo os oftalmologistas, 18,1% eram casos de urgência e 83,2% dos casos poderiam ter sido resolvidos em serviços de menor complexidade. Dos pacientes, 55,2% apresentavam diagnóstico de inflamação/infecção; 19,1% trauma. Conjuntivite viral foi o diagnóstico mais freqüente 24,6%, seguido por corpo estranho de córnea 7,5%, meibomite 6,4%. Entre os pacientes atendidos, os plantonistas classificaram 11,7% como retorno e 2,0% pós-operatório. Não houve diferença significativa no diagnóstico clínico entre os pacientes que vieram espontaneamente e os referenciados (p = 0,09). Em relação ao preenchimento das fichas administrativas, ressalta-se que 3,6% não constavam o nome do médico, 3,4% não constavam o CRM, 33,4% não foram preenchidos histórico ou observações clínicas; 6,3% só constavam o CID como diagnóstico. Concluiu-se que: a automedicação é muito difundida entre os pacientes e o uso de produtos caseiros se faz presente mesmo nos casos de urgência ocular. Os pacientes estão recebendo e entendendo explicações sobre o agravo ocular e sobre o tratamento prescrito. Os plantonistas vêm mantendo um bom relacionamento médico-paciente. O atendimento recebido pelo paciente foi considerado excelente. O Pronto-Socorro de Oftalmologia do Hospital das Clínicas é um hospital terciário que atende em sua maioria, casos primários e secundários; a maioria dos diagnósticos não foi considerada como urgência / We report a transversal, descriptive and analytical survey in a non-probabilistic promptly accessible sample, composed of 561 patients who looked for the Ophthalmology Emergency Room (E.R) of Clinics Hospital of the University of Sao Paulo School of Medicine during a regular week. Data were collected from administrative charts and from semi-structured questionnaire through interviews. The questionnaire also included an interview with the physician who assisted the patient. The study had the following purposes relative to the E.R patients: to describe social-demographic characteristics; reasons for search and choice of the hospital unit; to assess knowledge and conducts related to eye diseases and their causes and treatment; to assess previous ocular treatments; to identify the causes of compliance with treatment; to identify the reason for delayed search to medical treatment; to identify the knowledge about diagnosed diseases and prescribed treatment. Relative to the institution: to assess the rate of urgent and non-urgent ocular visits; to provide helpful data for ocular health assistance and educational interventions. Statistical analysis was performed using Stata software (version 9.0). The most important results were: most searches for the Emergency Room occurred during the day and on week-days; no statistically significant difference related to gender; average age was 39.8; and 91.1% of visits were assisted by the Public Health System. Most patients had low schooling and money income. Half of the patients did not belong to the area covered by Clinics Hospital. Forty-nine percent of the patients chose Clinics Hospital based to trust on the professionals and their competence; for 42.2% of the patients due to unavailability of ophthalmologists in the health units they are used to go to. The time taken to search assistance was between 24 hours and 1 (one) week for 40.8% of the patients. Such delay was due to the fact the 47% of the patients did not believe that their situation was urgent, and 34.1% searched another health unit before. Among those who searched another unit, 48.8% did not report worsening of health symptoms by the time they reached the E.R, while 39.6% did. Auto-medication was used previously to the E.R. visit by 40.5% of the patients, 29.4% of whom used home-made products. Most of these products were: boric water, physiologic saline solution, tap or well water, and herbs. No significant difference in auto-medication between man and women (p = 0.95), in different age levels (p= 0.14) or schooling levels (p= 0.21) was observed, neither in relation to work situation (p= 0.15) or place of residence (p= 0.52). Higher rates of auto-medication were observed among patients with ocular inflammation/ infection or trauma (49.5%), while 16.1% of the patients reported search for religious help to treat their disease. 95.1% of the patients reported having understood the information given about their condition. Among those patients to whom medication was prescribed, 95% understood how and why to use it. Approximately 50% of the patients graded with the maximum score the xxii xxiii assistance received. According to the ophthalmologists opinion, 18.1% of visits were real urgent cases, while 83.2% could have been attended at less complex health units. 52.2% of the patients were diagnosed with inflammation/infectious diseases; and 19.1% with trauma. Viral conjunctivitis was the most frequent diagnosis (24.6%), followed by corneal foreign bodies (7.5%), and meibomitis (6.4%). Considering assisted patients, physicians classified 11.7% as return visits and 2.0% as post-surgical visits. There was no significant difference on clinical diagnosis between patients on spontaneous or referred assistance (p= 0.09). As for the administration charts, it is important to emphasize that 3.6% of them did not contain the physicians name, 3.4% did not contain the professional registration number, 33.4% did not contain historical and clinical observations, and 6.3% only contained the International Classification of Diseases number. In conclusion, auto-medication is largely used among patients and the use of home-made products occurs even in urgent ocular situations. Patients are receiving and understanding the explanations about their ocular diseases and the prescribed treatment. E.R ophthalmologists have had a satisfactory physician-patient relationship. Medical assistance received by patients was considered excellent. Clinics Hospital Ophthalmologic E.R is a reference service which assists mostly primary and secondary cases, most of them being considered non-urgent

Artificiell intelligens eller intelligent läkekonst? : Om kropp, hälsa och ovisshet i digitaliseringens tidevarv / Artificial intelligence or intelligent art of medicine? : On body, health and uncertainty in the era of digitalization

Tamaddon, Leila January 2019 (has links)
Denna essä syftar till att ur filosofiska och idéhistoriska perspektiv belysa utmaningar och möjligheter med artificiell intelligens (AI) och digitalisering inom hälso- och sjukvården, med fokus på läkekonst, kropp, hälsa och ovisshet. Essän undersöker hur automatisering och digitala vårdformer omformar läkekonstens grund, nämligen mötet mellan patienten och läkaren. Genom en fenomenologisk kritik av AI och teknikens väsen, belyses skillnaden mellan människan och maskinen och hur den levda erfarenheten är situerad, förkroppsligad, fylld av mening och delad med andra. Essän utforskar hur situationsunik kunskap som praktisk klokhet, fronesis, samt ett reflekterande förnuft, intellectus,kan hantera den ovisshet som är inbäddad i det allmänmedicinska mötet. Essän belyser även hur digitalisering och AI passar väl med pågående marknadsanpassning av sjukvården, där homo economicus och homo digitalis båda omformar kropp och hälsa till mätbara resurser och data. Avslutningsvis lyfts etiska dilemman kring AI och digitalisering, samt vikten av praktisk och existentiell kunskap som förutsättningar för utvecklandet och designen av en teknik som syftar främja det mänskligt goda. / This essay aims to illuminate challenges and opportunities with artificial intelligence (AI) and digitalization in health care, focusing on the art of medicine, body, health and uncertainty. The theoretical framework is mainly within the fields of phenomenology and philosophical hermeneutics. The essay explores how automatization and digital health care are transforming the essence of medicine: the patient – physician encounter. By a phenomenological critique of AI and the essence of technology, the essay highlights the difference between machines and humans and how lived experience is situated, embodied, filled with meaning and shared with others. The essay explores how situational knowledge such as practical wisdom, phronesis, and reflective understanding, intellectus, can deal with the uncertainty that is embedded in the medical encounter in primary health care. The essay also highlights how digitalization and AI fit well with current market adaptation of health care, where homo economicus and homo digitalis both transform body and health into measurable resources and data. Finally, ethical dilemmas of AI and digitalization are highlighted, as well as the importance of practical and existential knowledge as preconditions for the development and design of a technology that aims to promote the human good.

Patient and other factors influencing the prescribing of cardiovascular prevention therapy in the general practice setting with and without nurse assessment

Mohammed, Mohammed A., El Sayed, C., Marshall, T. January 2012 (has links)
No / Although guidelines indicate when patients are eligible for antihypertensives and statins, little is known about whether general practitioners (GPs) follow this guidance. To determine the factors influencing GPs decisions to prescribe cardiovascular prevention drugs. DESIGN OF STUDY: Secondary analysis of data collected on patients whose cardiovascular risk factors were measured as part of a controlled study comparing nurse-led risk assessment (four practices) with GP-led risk assessment (two practices). SETTING: Six general practices in the West Midlands, England. PATIENTS: Five hundred patients: 297 assessed by the project nurse, 203 assessed by their GP. MEASUREMENTS: Cardiovascular risk factor data and whether statins or antihypertensives were prescribed. Multivariable logistic regression models investigated the relationship between prescription of preventive treatments and cardiovascular risk factors. RESULTS: Among patients assessed by their GP, statin prescribing was significantly associated only with a total cholesterol concentration >/= 7 mmol/L and antihypertensive prescribing only with blood pressure >/= 160/100 mm Hg. Patients prescribed an antihypertensive by their GP were five times more likely to be prescribed a statin. Among patients assessed by the project nurse, statin prescribing was significantly associated with age, sex, and all major cardiovascular risk factors. Antihypertensive prescribing was associated with blood pressures >/= 140/90 mm Hg and with 10-year cardiovascular risk. LIMITATIONS: Generalizability is limited, as this is a small analysis in the context of a specific cardiovascular prevention program. CONCLUSIONS: GP prescribing of preventive treatments appears to be largely determined by elevation of a single risk factor. When patients were assessed by the project nurse, prescribing was much more consistent with established guidelines.
