In this context serious problems arise, such as the use of multiple medications simultaneously (polypharmacy) that can lead to serious consequences to the elderly health. Another problem is the self-medication, which may exacerbate the associated risks with prescript drugs, delaying a diagnosis and masking a disease. There is, still, the use of drugs considered inappropriate for elderly, either by reducing the therapeutic efficacy or an increased risk of adverse effects that increase the advantages in elderly usage. Objective: Analyzing the pattern of use of medications in aged people in the city of Goiânia-GO, and associate it with socioeconomic aspects and with the self-rated health. Methods: A population-based study and cross-section, that evaluated the health of elderly in the city of Goiânia-GO. The data collection was carried out in December/2009 to April/2010 from 934 elderly. The questionnaire had questions about medications, in addition to information about self-rated health and socioeconomic profile. The drugs groups were classified according to the Anatomical Therapeutic Chemical and Classification-ATC. The inappropriate drugs for elderly were identified according to Beers Criteria. Used Mann Whitney (U) and Chi-square test, it was considered significant p<0.05. Results: Among 934 elderly participants of the survey, 783 (83.8%) had answered completely to the questionnaire. These 738 elderly used 2846 drugs (3.63 drugs/elderly). Women consumed more medication than men (3.94 and 3.06 respectively, p <0.001). The most frequently consumed drugs act on the cardiovascular system (38.6%). The prevalence of polypharmacy was 26.4% and 35.7% of the elderly told to practise self-medication. The drugs most commonly used by self-medication were the painkillers (30.8%). According to Beers-Fick Criteria, 24.6% of the elderly used inappropriate drugs, 90.2% of these drugs came from a current prescription. The inappropriate drugs more consumed were benzodiazepines (34.2%). Women, widows, elderly with 80 years or more and those who had a worse self-rated health practiced more polypharmacy (p<0.05). Elderly people with lower education and with worse self-rated health practiced more self-medication (p<0.05). Conclusions: The results of this study showed that the pattern of drug use by elderly of Goiânia was similar to that found in elderly people from other regions of Brazil. Since the number of drugs used, the prevalence of polypharmacy and self-medication practices and the use of inappropriate drugs were within the national average. Women, widows, aged 80 years or more and those who consider their health as poor more often practiced polypharmacy, the largest self-medication was associated with a lower education and poorer self-rated health. / Introdução: A maior convivência com doenças crônicas faz dos idosos grandes usuários de serviços de saúde e possivelmente o grupo mais medicalizado da sociedade. Nesse contexto surgem sérios problemas, como o uso de vários medicamentos concomitantemente (polifarmácia) que pode levar a sérias consequencias à saúde do idoso. Pode ser citada também a prática da automedicação, que pode acentuar os riscos relacionados aos medicamentos prescritos, retardar um diagnóstico e mascarar uma doença. Além disso, têm-se o uso de medicamentos considerados impróprios para o idoso, seja por redução da eficácia terapêutica ou por um risco aumentado de efeitos adversos que superam seus benefícios. Objetivo: Analisar o padrão do uso de medicamentos em idosos no município de Goiânia, Goiás e associá-lo com aspectos socioeconômicos e com a autopercepção de saúde. Métodos: Estudo de base populacional e delineamento transversal, que avaliou o uso de medicamentos em idosos no município de Goiânia-GO. Foram coletados dados de 934 idosos no período entre dezembro/2009 e abril/2010. No questionário aplicado havia questões sobre medicamentos, além de informações sobre autopercepção de saúde e o perfil socioeconômico. Os medicamentos usados pelos idosos foram classificados segundo o Anatomical Therapeutic and Chemical Classification-ATC. Os medicamentos impróprios para idosos foram identificados segundo Critério de Beers-Fick. Utilizou-se Teste de Mann Whitney (U) e Qui-quadrado, considerando significativo p<0,05. Resultados: Dos 934 idosos participantes do inquérito, 783 (83,8%) responderam completamente ao questionário. Esses 783 idosos usavam 2.846 medicamentos (3,63 medicamentos/idoso). As mulheres usavam mais medicamentos que os homens (3,94 e 3,06 respectivamente, p<0,001). Os medicamentos mais usados atuam no aparelho cardiovascular (38,6%). A prevalência de polifarmácia foi de 26,4% e 35,7% dos idosos relatou praticar automedicação. Os medicamentos mais usados por automedicação foram os analgésicos (30,8%). Segundo os critérios de Beers-Fick, 24,6% dos idosos usava pelo menos um medicamento considerado impróprio, 90,2% desses medicamentos era proveniente de uma receita médica atual. Os medicamentos impróprios mais usados foram os benzodiazepínicos (34,2%). Mulheres, viúvos, idosos com 80 anos ou mais e os que apresentaram pior autopercepção de saúde praticavam mais a polifarmácia (p<0,05). Idosos com menor escolaridade e com pior autopercepção de saúde praticavam mais a automedicação (p<0,05). Conclusões: Os resultados desse estudo mostraram que o padrão do uso de medicamentos por idosos goianieneses foi semelhante ao encontrado em idosos de outras regiões do Brasil. Visto que o número de medicamentos usados, a prevalência das práticas da polifarmácia e automedicação e o uso de medicamentos impróprios estiveram dentro da média nacional. Mulheres, viúvos, idosos com 80 anos ou mais e aqueles que consideram sua saúde como ruim praticavam com maior frequência a polifarmácia; a maior prática da automedicação esteve associada com uma menor escolaridade e uma pior autopercepção de saúde.

Background Based on changes in pharmacokinetics and –dynamics in elderly patients, there are potentially inappropriate medications (PIM) that should be avoided in patients aged ≥ 65 years. Current studies showed prescription rates of PIM between 22.5 and 28.4 % in the primary care setting. The evidence concerning reasons for PIM prescription by FPs is limited. Methods This mixed method study consisted of three research parts: 1) semi-standardized content analysis of patients’ records, 2) qualitative interviews with FPs using a) open questions and b) selected patient-specific case vignettes and 3) qualitative interviews with FPs’ medical assistants. The integration of qualitative interviews was used to explain the quantitative results (triangulation design). PIM were identified according to the German PRISCUS list. Descriptive and multivariate statistical analysis was done using SPSS 22.0. Qualitative content analysis of interviews was used to classify the content of the interviews for indicating pertinent categories. All data were pseudonymously recorded and analyzed. Results Content analysis of 1846 patients’ records and interviews with 7 related FPs were conducted. Elderly patients [n = 1241, mean age: 76, females: 56.6 %] were characterized in average by 8.3 documented chronic diagnosis. 23.9 % of elderly patients received at least one PIM prescription. Sedatives/hypnotics were the most frequent prescribed PIM-drugs (13.7 %). Mental disorders, gender and number of long-term medication were detected as predictors for the probability of a PIM prescription. Common reported reasons for PIM prescription by FPs concerned limited knowledge regarding PIM, limited applicability of PIM lists in daily practice, lack of time, having no alternatives in medication, stronger patient-related factors than age that influence prescription, own bad experiences regarding changes of medication or refusal of following prescriptions of sedative/hypnotics. Conclusions It is essential to see FPs in a complex decision making situation with several influencing factors on their prescribing, including: patient-oriented prioritization, FPs’ experiences in daily practice, FPs’ knowledge regarding existing recommendations and their trust in it and organizational characteristics of FPs’ daily medical practice. These pros and cons of PIM prescription in elderly patients should be considered in FPs’ advanced training.

Pesquisas nacionais que investigaram esse tema revelam que as prevalências de uso de MPIs variam de 28,0% a 82,6%; contudo, esses estudos utilizaram listas de MPIs validadas na América do Norte e Europa, uma vez que o primeiro consenso brasileiro sobre MPIs foi publicado somente no final de 2016. Segundo os autores, a lista desenvolvida apresenta algumas lacunas no conhecimento, uma vez que foi baseada em critérios publicados até 2012 e, portanto, não inclui as versões mais atualizadas publicadas em 2015, bem como não incorpora possíveis alternativas terapêuticas para os medicamentos que compõem a lista. Dessa forma, este estudo teve como objetivo estabelecer critérios explícitos para avaliação de MPIs prescritos aos idosos no Brasil e suas respetivas alternativas terapêuticas. O projeto englobou duas etapas complementares: 1- Elaboração da lista de critérios explícitos para avaliação de medicamentos inapropriados para idosos a partir de revisão sistemática já realizada; 2- Validação da proposta por consenso de especialistas utilizando técnica Delphi; A primeira etapa, elaboração da lista preliminar de MPIs, foi baseada em um estudo de revisão sistemática das listas publicadas entre janeiro/1991 e abril/2017.Realizou-se também uma análise qualitativa das listas com o objetivo de verificar a aplicabilidade destas ao mercado brasileiro em termos de disponibilidade e frequência de prescrição. Dessa forma, selecionaram-se três listas de MPIs: Beers 2015, STOPP 2015, European Union (7) PIM list. Ao final desse processo, obteve-se 153 critérios distribuídos em sete instrumentos: Dor e Inflamação, Sistema Cardiovascular, Sistema Endócrino, Geniturinário, Sistema Respiratório, Sistema Nervoso Central, sendo os dois primeiros já validados por meio da técnica Delphi modificada. Considerou-se validados os itens para os quais o limite inferior do IC 95% foi superior ou igual a 4,0. O consenso sobre MPIs - Dor e inflamação foi constituído duas rodadas. Um grupo de nove especialistas atingiu consenso sobre 98 (63,2%) das 155 questões apresentadas: 31/34 preocupações independente do diagnóstico, 4/4 preocupações quanto à dose, 4/4 preocupações quanto a duração do tratamento, 19/20 preocupações quanto ao uso em condições específicas, 12/23 considerações especiais de uso e 28/68 alternativas terapêuticas. No consenso sobre MPIs -Sistema Cardiovascular, um grupo de sete especialista atingiu consenso sobre 84 das 257 questões apresentadas: 20/25 preocupações independente do diagnóstico, 4/4 preocupações quanto à dose, 37/57 preocupações quanto ao uso em condições específicas, 20/105 considerações especiais de uso e 3/66 alternativas terapêuticas. Embora a validação de listas de MPIs a partir da opinião de especialistas seja um processo complexo, a listas desenvolvidas poderão ampliar o conhecimento sobre MPIs no país, uma vez que são baseadas em consensos recentes. Desse modo, esta pesquisa possibilitará um melhor entendimento da magnitude do uso de MPIs no Brasil, e poderá contribuir para o desenvolvimento de estratégias e intervenções mais eficazes para a redução dos problemas relacionados ao uso de medicamentos em idosos no país. / The use of potentially inappropriate medications (PIMs) for older patients is a public health problem because it can compromise the effectiveness or safety of pharmacotherapy and is responsible for high rates of morbidity and mortality in this age group. Brazilian studies that investigated PIMs show that the prevalence of PIM use ranges from 28.0% to 82.6%. However, these studies used PIM lists developed in other countries in North America and Europe. The first Brazilian consensus on PIMs was published in 2016. Limitations reported by the authors included that the PIM list was based on previous versions of Beers (2012) and STOPP (2008), therefore, it did not include the most up-to-date versions published in 2015, and did not incorporate therapeutic alternatives. The aim of the present study is to develop and validate explicit criteria for the evaluation of PIMs prescribed to older patients in Brazil and their respective therapeutic alternatives. The development of this project comprises of two steps: 1- Elaboration of the preliminary PIM list for older patients based on a systematic literature review; 2 - Validation of the preliminary PIM list with the consensus of experts using modified Delphi technique; The elaboration of the preliminary list of MPIs was based on a systematic review of PIM lists published between January 1991 and April 2017. A qualitative analysis of the PIM lists was performed with the objective of verifying their applicability to the Brazilian market. This way, three lists of PIMs were selected: Beers’ 2015, STOPP 2015, and European Union (7) PIM. Thus, we obtained 153 explicit criteria distributed across seven instruments: PIMs–Pain and Inflammation, PIMs–Cardiovascular System, PIMs–Endocrine System, PIMs–Genitourinary, PIMs–Respiratory System, and PIMs–Central Nervous System. The first two were already validated using the modified Delphi technique. The items for which the lower limit of the 95% confidence interval (CI) was greater than or equal to 4.0 were considered to have been validated. The consensus on PIMs–Pain and Inflammation was formed by two rounds. A group of nine experts reached consensus on 98 (63.2%) of the 155 items. A consensus was reached for 31/34 concerns regardless of diagnosis, 4/4 dose concerns, 4/4 concerns about the duration of treatment, 19/20 concerns about use under specific conditions, 12/23 special considerations of use, and 28/68 therapeutic alternatives. In the consensus on PIMs–Cardiovascular System, a group of seven experts reached consensus on 84 of the 257 questions. A consensus was reached for 20/25 concerns independent of diagnosis, 4/4 concerns regarding dose, 37/57 concerns regarding use under specific conditions, 20/105 special considerations of use and 3/66 therapeutic alternatives. Although the development and validation of PIM lists based on expert opinion is a long and complex process, the development of PIM list based on recent consensuses will expand the knowledge about the PIMs in Brazil. Thus, this research will improve the understanding of the magnitude of PIM use in this country, and may contribute to the development of more effective strategies and interventions to reduce drug-related problems among older Brazilian patients.

Schätzungen über die Gesamtzahl der Vergiftungen in Deutschland belaufen sich auf 150 - 200.000 pro Jahr. In Deutschland machen Vergiftungsfälle 10% der in Notaufnahmen und auf Intensivstationen behandelten Patienten aus. Bis dato gibt es in Deutschland nur wenige strukturiert erfasste epidemiologische Daten von vergiftungsbedingten Todesfällen. In der vorliegenden Arbeit wurden die vergiftungsbedingten Todesfälle aus dem Giftinformationszentrum-Nord (GIZ-Nord) für den Zeitraum vom 01.01.1996 bis einschließlich 31.12.2009 retrospektiv analysiert. Insbesondere vor dem Hintergrund der Toxikovigilanz konnten folgende Fragen zu Risikokonstellationen für letale Vergiftungen durch diese Arbeit beantwortet werden: 1. Gibt es bei den vergiftungsbedingten Todesfällen jahreszeitliche Schwankungen? Ja, die vergiftungsbedingten bzw. suizidalen letalen Intoxikationen zeigen jahreszeitliche Schwankungen mit einem maximalen Anteil im Frühling von knapp 30% und dem geringsten Anteil im Herbst mit etwa 20%. 2. Bergen die iatrogen bedingten Vergiftungen ein besonderes Mortalitätsrisiko? Ja, die iatrogenen Vergiftungen weisen die höchste Mortalitätsrate mit knapp 5 &permil; aller iatrogenen Expositionen auf, vor allem bei parenteraler Arzneimittelapplikation. 3. Stellen Adoleszente (Heranwachsende und Jugendliche) und Senioren über 70 Jahre besonders gefährdete Altersgruppen für letale Intoxikationen dar? Ja, beide Populationen stellen besondere Risikogruppen für vergiftungsbedingte Todesfälle dar. Vor allem männliche Heranwachsende repräsentieren eine Risikogruppe für letale Intoxikationen durch Abusus. 30% aller vergiftungbedingten Todesfälle durch Abusus sind bei männlichen Jugendlichen aufgetreten. Senioren (Männer und Frauen) über 70 Jahre sind eine im hohen Maß gefährdete Altersgruppe für letale Vergiftungen. Einerseits ist die relative Mortalitätsrate bezogen auf alle Expositionen dieser Altersgruppe mit knapp 6 &permil; am höchsten. Andererseits zeigen die suizidalen Intoxikationen bei den Senioren eine zunehmende Tendenz. Außerdem bilden Senioren mit einem Anteil von 24% die Gruppe mit dem größten Anteil an den letalen nicht suizidalen Intoxikationen. Mehr als 70% der akzidentellen letalen Intoxikationen und 50% der letalen Vergiftungen durch Verwechslungen betreffen Senioren, dabei sind Frauen mehr als 3fach häufiger betroffen als Männer. Darüber hinaus sind Senioren durch Aspiration schäumender, prinzipiell niedrig toxischer Kosmetika und tensidhaltiger Chemikalien besonders gefährdet. 4. Gibt es bei den gewerblichen Expositionen besondere Risikokonstellationen? Ja, die gewerblichen Expositionen, die mit einer hohen Männerlastigkeit auftreten, bergen eine hohe letale Intoxikationsgefahr. Vor allem bei den gewerblichen inhalativen Expositionen von toxischen Reizgasen besteht eine Gefährdung für die betroffenen Beschäftigten, aber auch für die nicht selbstgeschützten Ersthelfer: 6% der inhalativen gewerblichen Intoxikationen durch Schwefelwasserstoff endeten letal.
