Potencialidades e limitações da Rede Sentinela para o aperfeiçoamento do monitoramento pós-comercialização/pós-uso de produtos sob vigilância sanitária adotado pela Anvisa

Introduction: Hospitals are essential for the universal coverage of any health system, as well as sources of  valuable information on adverse events and technical complaints of products subjects to health surveillance. Objective: To identify the potentialities and limitations of the Sentinel Network to improve post-marketing/post-use monitoring of products subject to health surveillance adopted by Anvisa. Method: A descriptive quantitative study that used data from a national administrative survey applied to the Sentinel Network, which was conducted between August 4 and September 2, 2021, by the Anvisa. Data were collected using an electronic structured  questionnaire. Statistical analyzes were performed in the Gretl-2022a software, including the calculation of absolute and relative frequencies, medians, and interquartile ranges. Results: A response rate of 69.1% (181/262) was obtained. Among the potentialities, the following stand out: acting as a center for study, teaching, and research of health establishments (n = 145; 80.1%), presence of implanted electronic medical records (n = 142; 78.4%) and the development of initiatives focused on innovation involving risk management of health products (n = 94; 52.0%). As one of the limitations, health establishments that do not have any current excellence/quality certifications predominate (n = 104; 57.5%). Conclusions: The Sentinel Network has  several potentialities and limitations that affect the post-marketing/post-use monitoring of products subject to  health surveillance. Identifying them, as was the objective of this study, demonstrates the need to promote actions that offer the possibility of expanding the potentialities and mitigate the limiting factors to the improvement of post-marketing/post-use monitoring adopted by Anvisa.Introdução: Os hospitais são essenciais para a cobertura universal de qualquer sistema de saúde, bem como são fontes de informações valiosas sobre eventos adversos e queixas técnicas de produtos sob vigilância sanitária.

Método: Estudo descritivo quantitativo que utilizou dados de levantamento administrativo nacional aplicado à Rede Sentinela realizado entre 4 de agosto e 2 de setembro de 2021 pela Anvisa. Os dados foram coletados por meio de questionário estruturado eletrônico. As análises estatísticas foram executadas no software Gretl-2022a, compreendendo o cálculo das frequências absoluta e relativa, medianas e  intervalos interquartis. Resultados: Obteve-se uma taxa de resposta de 69,1% (181/262). Dentre as potencialidades, destacam-se: a atuação como centro de estudo, ensino e pesquisa dos estabelecimentos de saúde (n = 145; 80,1%), a presença de prontuário eletrônico implantado (n = 142; 78,4%) e o desenvolvimento de iniciativas voltadas para a inovação envolvendo a gestão de risco de produtos de saúde (n = 94; 52,0%). Como uma das limitações,   predominam os estabelecimentos de saúde que não possuem quaisquer certificações de excelência/qualidade vigentes (n = 104; 57,5%). Conclusões: A Rede Sentinela apresenta várias potencialidades e limitações que afetam o monitoramento pós-comercialização/pós-uso de produtos sob vigilância sanitária. Identificá-las, como foi o objetivo deste estudo, demonstra a necessidade de fomentar ações que ofereçam a possibilidade de ampliar as potencialidades e mitigar os fatores limitantes ao aperfeiçoamento do  monitoramento pós-comercialização/pós-uso adotado pela Anvisa

Molecular investigation of isolates from a multistate polymicrobial outbreak associated with contaminated total parenteral nutrition in Brazil

Background: Between November 2013 and June 2014, 56 cases of bacteremia (15 deaths) associated with the use of Total Parenteral Nutrition (TPN) and/or calcium gluconate (CG) were reported in four Brazilian states. Methods: We analyzed 73 bacterial isolates from four states: 45 from blood, 25 from TPN and three from CG, originally identified as Acinetobacter baumannii, Rhizobium radiobacter, Pantoea sp. or Enterobacteriaceae using molecular methods. Results: The first two bacterial species were confirmed while the third group of species could not be identified using standard identification protocols. These isolates were subsequently identified by Multi-Locus Sequence Analysis as Phytobacter diazotrophicus, a species related to strains from similar outbreaks in the United States in the 1970’s. Within each species, TPN and blood isolates proved to be clonal, whereas the R. radiobacter isolates retrieved from CG were found to be unrelated. Conclusion: This is the first report of a three-species outbreak caused by TPN contaminated with A. baumannii, R. radiobacter and P. diazotrophicus. The concomitant presence of clonal A. baumannii and P. diazotrophicus isolates in several TPN and blood samples, as well as the case of one patient, where all three different species were isolated simultaneously, suggest that the outbreak may be ascribed to a discrete contamination of TPN. In addition, this study highlights the clinical relevance of P. diazotrophicus, which has been involved in outbreaks in the past, but was often misidentified as P. agglomerans

A segurança do paciente cirúrgico na perspectiva da vigilância sanitária — uma reflexão teórica

With the aim of preventing healthcare risks, improving health, and promoting patient safety, various measures have been implemented. Patient safety is equated to the re-duction of risk of unnecessary harm associated with healthcare to an acceptable mi-nimum. An incident that results in harm to a patient is known as Adverse Event (AE). Surgery-related AEs remain to be a global public health challenge. In Brazil, the National Health Surveillance Agency (ANVISA) and Ministry of Health have delineated actions, po-licies, and health regulation to prevent AEs, including those resulting from surgical pro-cedures. In 2013, the National Patient Safety Program was established and the actions of patient safety were regulated by ANVISA. Despite progresses in the recently established national security policy for patients, further measures are still required to improve the quality and safety of surgical care. The creation and maintenance of a safety culture in healthcare services will assure safer surgical procedures. Thus, this study aimed to discuss the primary components related to healthcare quality and patient safety that are considered as priority in healthcare services and discuss strategies employed by the government to promote safe surgical care.Diversas medidas de prevenção dos riscos relacionados à assistência e à melhoria da saúde são desenvolvidas em favor da segurança do paciente. A segurança do paciente é entendida como a redução, a um mínimo aceitável, do risco de dano desnecessário associado à atenção à saúde. Danos desnecessários são conhecidos como Eventos Ad-versos (EAs). A preocupação com a segurança cirúrgica constitui um desafio mundial de saúde pública. No Brasil, a Agência Nacional de Vigilância Sanitária (ANVISA) e o Ministério da Saúde delinearam ações, política e regulamentação sanitária para prevenir EAs, incluindo aqueles decorrentes de procedimentos cirúrgicos. Em 2013 foi instituído o Programa Nacional de Segurança do Paciente (PNSP), e a ANVISA regulamentou as ações de segurança do paciente. Apesar dos avanços da política nacional de segurança do pa-ciente, recentemente instituída no país, ainda são necessárias medidas visando a busca da qualidade e da segurança nos cuidados cirúrgicos. A instituição e a sustentação de cultura de segurança pode asseverar a cirurgia segura nos serviços de saúde. O objetivo deste artigo é discutir os principais componentes envolvidos na qualidade do cuidado e da segurança do paciente, como prioridades nos serviços de saúde e nas estratégias nacionais empregadas para a promoção da assistência cirúrgica segura

The global spread of HIV-1 subtype B epidemic

Human immunodeficiency virus type 1 (HIV-1) was discovered in the early 1980s when the virus had already established a pandemic. For at least three decades the epidemic in the Western World has been dominated by subtype B infections, as part of a sub-epidemic that traveled from Africa through Haiti to United States. However, the pattern of the subsequent spread still remains poorly understood. Here we analyze a large dataset of globally representative HIV-1 subtype B strains to map their spread around the world over the last 50 years and describe significant spread patterns. We show that subtype B travelled from North America to Western Europe in different occasions, while Central/Eastern Europe remained isolated for the most part of the early epidemic. Looking with more detail in European countries we see that the United Kingdom, France and Switzerland exchanged viral isolates with non-European countries than with European ones. The observed pattern is likely to mirror geopolitical landmarks in the post-World War II era, namely the rise and the fall of the Iron Curtain and the European colonialism. In conclusion, HIV-1 spread through specific migration routes which are consistent with geopolitical factors that affected human activities during the last 50 years, such as migration, tourism and trade. Our findings support the argument that epidemic control policies should be global and incorporate political and socioeconomic factors
