RESUMEN
BACKGROUND: Laboratory medicine is an important part of the healthcare system and directly contributes to preventive actions, diagnostics, treatment, and management of diseases. The level and quality of the utilization of laboratory resources have been frequently questioned. A dissemination of conflicting data regarding the quantity of laboratory tests not accessed by the requesting doctors or by the patients themselves is observed, although very often the sources and methodologies used to raise those numbers are not properly clarified. The objective of this study was to obtain data about access to results of tests taken in Brazilian private clinical analysis laboratories which use the laboratory information system developed by SHIFT Consultoria e Sistemas. METHODS: Information was extracted from 81 laboratories, which were responsible for the performance of 93,240,651 tests, collected from 7,067,087 patients. RESULTS: The total number of tests not accessed, considering all the regions, was 5,071,454, corresponding to a proportion of 5.4%. In the face of the potential risks of adverse events or impacts in the management of diagnostics and treatments, including economic impacts due to prolonged hospitalization time, the proportion of 17.9% which was found corresponding to tests "not accessed" showing "abnormal" results, is worrisome, mainly if we observe that of those, 2.5% were related to "abnormal" test results processed by laboratories which work in hospital care. CONCLUSIONS: SBPC/ML, in face of the relevance of the theme, will keep stimulating the monitoring and utilization of adequate laboratory resources, in order to allow sustainable healthcare systems.

BACKGROUND: The use of point-of-care testing (POCT) in different clinical applications is justified by the fact that the time to release the result is shortened, allowing the physician to define the diagnosis and most appropriate therapy in a shorter time. However, the negative aspects must also be highlighted and studied so that we can move forward with the use of these devices. These negative aspects include greater analytical imprecision compared to laboratory automation, the variability between different equipment from different manufacturers, the risk of inappropriate use, a low level of global regulation, higher costs compared with laboratory testing and cost ineffectiveness in terms of health care. Methods and. RESULTS: This review presents some clinical applications of POCT in different scenarios, such as for diabetes mellitus, infectious diseases, pediatrics, and chronic kidney disease, among others. CONCLUSIONS: We hope to see a global consensus on an acceptable quality standard for performing POCT that is adaptable, practical, and cost effective in primary care settings, ensuring patient safety, and minimizing the risk of harm.

Point-of-Care Testing (POCT) has been highlighted in the health care sector in recent decades. On the other hand, due to its low demand, POCT is at a disadvantage compared to conventional equipment, since its cost is inversely proportional to the volume of use. In addition, for the implementation of POCT to succeed, it is essential to rely on the work of a multidisciplinary team. The awareness of health professionals of the importance of each step is perhaps the critical success factor. The trend towards the continuous advancement of the use of POCT and the great potential of its contributions reinforce the need to implement quality management tools, including performance indicators, to ensure their results. This review presents some advantages and disadvantages concerning POCT and the real need to use it. A worldwide call for the availability of easy-to-use health technologies that are increasingly closer to the final user is one of the main reasons for this focus.

The improving quality of laboratory testing requires a deep understanding of the many vulnerable steps involved in the total examination process (TEP), along with the identification of a hierarchy of risks and challenges that need to be addressed. From this perspective, the Working Group "Laboratory Errors and Patient Safety" (WG-LEPS) of International Federation of Clinical Chemistry and Laboratory Medicine (IFCC) is focusing its activity on implementation of an efficient tool for obtaining meaningful information on the risk of errors developing throughout the TEP, and for establishing reliable information about error frequencies and their distribution. More recently, the European Federation of Clinical Chemistry and Laboratory Medicine (EFLM) has created the Task and Finish Group "Performance specifications for the extra-analytical phases" (TFG-PSEP) for defining performance specifications for extra-analytical phases. Both the IFCC and EFLM groups are working to provide laboratories with a system to evaluate their performances and recognize the critical aspects where improvement actions are needed. A Consensus Conference was organized in Padova, Italy, in 2016 in order to bring together all the experts and interested parties to achieve a consensus for effective harmonization of quality indicators (QIs). A general agreement was achieved and the main outcomes have been the release of a new version of model of quality indicators (MQI), the approval of a criterion for establishing performance specifications and the definition of the type of information that should be provided within the report to the clinical laboratories participating to the QIs project.

Quality indicators (QIs) are fundamental tools for enabling users to quantify the quality of all operational processes by comparing it against a defined criterion. QIs data should be collected over time to identify, correct, and continuously monitor defects and improve performance and patient safety by identifying and implementing effective interventions. According to the international standard for medical laboratories accreditation, the laboratory shall establish and periodically review QIs to monitor and evaluate performance throughout critical aspects of pre-, intra-, and post-analytical processes. However, while some interesting programs on indicators in the total testing process have been developed in some countries, there is no consensus for the production of joint recommendations focusing on the adoption of universal QIs and common terminology in the total testing process. A preliminary agreement has been achieved in a Consensus Conference organized in Padua in 2013, after revising the model of quality indicators (MQI) developed by the Working Group on "Laboratory Errors and Patient Safety" of the International Federation of Clinical Chemistry and Laboratory Medicine (IFCC). The consensually accepted list of QIs, which takes into consideration both their importance and applicability, should be tested by all potentially interested clinical laboratories to identify further steps in the harmonization project.

OBJECTIVES: This study aimed at the simultaneous assessment of culture and laboratory practices related to patient safety in Brazilian laboratories, and validation of the proposed questionnaire. METHODS: The questionnaire was based on the Hospital Survey on Patient Safety Culture, used by the 1.0 version of the Agency of Healthcare Research and Quality and other bibliographical references. The sample consisted of 1414 professionals from 51 different Brazilian clinical laboratories. Agency of Healthcare Research and Quality criteria were used to define "strengths and weaknesses" related to patient safety. The psychometric evaluation of the questionnaire included the analysis of reliability and validity. RESULTS: Patient safety in the laboratories was considered "excellent" (35.22%), "very good" (53.14%), "regular" (10.11%), "bad" (0.92%), and "very bad" (0.61%). The only dimension of culture with positivity less than 50% was "nonpunitive responses to errors" (30.74%). The dimensions on laboratory practices related to patient safety revealed positivity greater than 60%, with the "analytical" dimension (76.47%) being the highest. The psychometric evaluation revealed the reliability of the questionnaire, the applicability of 12 dimensions to assess culture, and 4 or 5 dimensions to assess laboratory practices related to patient safety. CONCLUSIONS: The culture and practices related to patient safety in Brazilian laboratories were evaluated as good, although a punitive culture against the occurrence of errors was identified. The psychometric evaluation of the questionnaire confirmed its reliability and validity. Studies performed in a larger and more diverse sample of clinical laboratories are needed to confirm the results obtained.

OBJECTIVES: In the laboratory medicine segment, benchmarking is the process in which institutions seek to compare with the macro environment (performance comparison and best practices with different laboratories) and improve their results based on quality indicators. The literature has highlighted the vulnerability of the pre-analytical phase in terms of risks and failures and the use of interlaboratory comparison as an opportunity to define a strategic performance benchmark aligned with the laboratory medicine sector, which has been a promising strategy to ensure continuous improvement, identifying within the pre-analytical process the critical activities to guarantee patient safety. In this context, this paper aims to present the three-year experience (2016-2018) of the Benchmarking Program and Laboratory Indicators - in Portuguese, Programa de Benchmarking e Indicadores Laboratoriais (PBIL) - with emphasis on pre-analytical indicators and their comparison against literature references and other programs of benchmarking in the area of laboratory medicine. PBIL is organized by the Brazilian Society of Clinical Pathology/Laboratory Medicine (SBPC/ML) in conjunction with Controllab and coordinated by a Brazilian group with representatives from different countries. METHODS: The data presented in this paper involving the performance results of 180 laboratories with active participation. Results are presented in percentage (%, boxplot graphical in quartiles) and Sigma metric, recognized as the metric that best indicates the magnitude of failures in a process. The Pareto Chart was used to facilitate ordering and to identify the main errors in the pre-analytical phase. The Radar Chart was made available in this work for the purpose of comparing the results obtained in Sigma by the PBIL and IFCC Working Group Laboratory Errors and Patient Safety (WG LEPS). RESULTS: In the study period, just over 80% of the pre-analytical failures are related to Blood culture contamination (hospital-based and non-hospital-based laboratories), Recollect and Non-registered exams, with failure rates of 2.70, 1.05 and 0.63%, respectively. The performance of the PBIL program participants was in line with the literature references, and allowed to identify benchmarks in the laboratory medicine market, target of PBIL, with best practices were observed for some indicators. CONCLUSIONS: The results of the program demonstrate the importance of an ongoing program comparative performance-monitoring program for setting more robust goals and consequently reducing laboratory process failures. Even with these promising premises and results, the contextualized analysis of the program indicators, point to a still significant number of failures in our market, with possibilities for improvement in order aiming to ensure more robust and effective processes.

RESUMEN
A Sociedade Brasileira de Patologia Clínica/Medicina Laboratorial (SBPC/ML) lançou, em seu 44º Congresso Brasileiro de Patologia Clínica e Medicina Laboratorial, uma série de recomendações para minimizar os erros na fase pré-analítica, sendo este texto uma delas. Além do crescimento do mercado de testes moleculares, é frequente a percepção errônea de que esses testes são menos sujeitos a erros. Enfatizamos, neste documento, que certos cuidados na fase pré-analítica são extremamente importantes para garantir a confiabilidade de testes moleculares.
The Brazilian Society of Clinical Pathology/Laboratory Medicine (SBPC/ML) launched a series of recommendations on how to minimize errors on the pre-analytical testing phase during the 44th Brazilian Congress of Clinical Pathology and Laboratory Medicine. This is one of them. The molecular diagnostics market is growing fast and many people believe these tests are less error-prone. In this study we highlight that proper care during the pre-analytical phase is extremely important in order to ensure the reliability of molecular diagnostic tests.
RESUMEN
Introdução - Os laboratórios clínicos são parte da cadeia de assistência à saúde, exercendo, historicamente, importante papel no suporte às decisões clínicas. A realização de exames laboratoriais ocorre num ambiente complexo, onde coexistem procedimentos, equipamentos, tecnologia e conhecimento humano, com o objetivo de garantir resultados que orientem decisões diagnósticas e terapêuticas. Informações laboratoriais erradas, ocasionadas por falhas no processo laboratorial e transmitidas aos médicos, podem afetar diretamente os resultados da assistência e a segurança do paciente.Metodologia - Foi realizada uma revisão sistemática, com o objetivo de identificar estudos sobre erros laboratoriais relacionados à segurança do paciente e seus efeitos, entendendo-se segurança do paciente como a redução, ao mínimo aceitável, do risco de dano desnecessário associado à assistência à saúde (OMS, 2009). Os estudos foram categorizados pelos a) métodos empregados e b) pela frequência dos incidentes. As metodologias utilizadas pelos autores dos estudos incluídos foram discutidas quanto à possibilidade de aplicação no Brasil, para fins de monitoramento de erros laboratoriais e prevenção de eventos adversos deles decorrentes. As fontes bibliográficas utilizadas nas buscas eletrônicas foram: MEDLINE, por meio da interface do PubMed, COCHRANE, LILACS, ScieELO, SCOPUS, WEB of SCIENCE e o banco de dados de teses e dissertações da Coordenadoria de Aperfeiçoamento de Pessoal de Nível Superior (CAPES). Os incidentes descritos nos estudos foram classificados quanto: a) à fase do processo laboratorial envolvida; b) ao caráter cognitivo; c) à evitabilidade e d) ao impacto na segurança do paciente. Resultados Foram encontrados nove artigos, que descreveram eventos adversos originados de erros laboratoriais, de acordo com os critérios pré-definidos. Os estudos abrangeram diferentes tipos de laboratórios, setores técnicos e origem de erros, segundo a fase do processo laboratorial. Os estudos selecionados evidenciaram eventos adversos relacionados a erros laboratoriais e fornecem uma gama de métodos que poderiam ser utilizados na realidade brasileira, e que permitiriam conhecer melhor e monitorar danos aos pacientes causados pelos erros cometidos nos laboratórios clínicos. As proporções de eventos adversos relatados e os impactos clínicos variaram, levando à consequências descritas como: desde nenhuma influência na assistência, até a danos decorrentes da flebotomia, recoleta de amostras, repetições de exames, atrasos na liberação de resultados de exames, influência no diagnóstico e/ou tratamento tratamentos impróprios e/ou desnecessários, realização de investigação adicional desnecessária, internação em unidade de terapia intensiva e óbitos. Conclusão: Existem estudos que associam eventos adversos a erros laboratoriais. Algumas metodologias utilizadas nos estudos podem ser aplicadas no Brasil, de modo a propiciar o conhecimento da magnitude do problema e traçar estratégias visando à prevenção de eventos adversos, à melhoria e monitoramento contínuo dos serviços laboratoriais.
