“…External validation is usually done through EQAS (External Quality Assessment Scheme). EQAS helps the laboratories assess their accuracy as well as bias of their results and stability of methods over a [3] longer period of time. Authors planned this study in order to provide the Quality assured biochemical testing by validating the results of serum parameters tested by the new autoanalyzer (here-to-fore referred as 'X') by comparing the results with an existing EQAS proven externally validated [4] autoanalyzer (here-to-fore referred as 'Y').…”

Evidence-based medicine is basically a positivistic, biomedical perspective. Its focus is on offering clinicians the best available evidence about the most adequate treatment for their patients. In the Era of Evidence based Medicine, the Diagnosis & Treatment protocol is largely dependent on the Diagnostic Tests of which a lions part is Biochemical Tests. Due to Automation many companies are coming up with new machines everyday. There lies the importance of Validity of an instrument. Authors planned this study in order to provide the Quality assured biochemical testing by validating the new autoanalyzer by comparing the results with an existing EQAS proven autoanalyzer. Comparative analysis chart of test results obtained by both the instruments were drawn, Comparative analysis was done, Statistical Linear Regression plot & Bland Altman plot were also drawn. 22 Unacceptable values & 18 Acceptable values out of 40 run in BIORAD Control Target Values of 10 Tested Parameters in case of Tested Analyzer. While all 40 are Acceptable values out of 40 run in BIORAD Control Target Values in case of Existing Analyzer obtained. ALT, T. Bilirubin, AST, Creatinine, Triglycerides Showing Negative bias. Glucose Showing Positive bias. Total Protein, Albumin not showing good correlation. ALP Showing High Constant error.

“…Um laboratório deve dispor de ferramentas adequadas à análise de não conformidades e implementação de ações corretivas e preventivas. 6 Uma dessas ferramentas é a avaliação externa da qualidade, que possibilita o rastreamento de oportunidades de melhoria em um laboratório ou rede de diagnósticos laboratoriais, o que é de grande importância quando se consideram doenças de interesse para a saúde pública. 7 A participação em programas de avaliação externa da qualidade é um dos requisitos das normas para funcionamento de um laboratório de saúde contemplados pela Associação Brasileira de Normas Técnicas (ABNT).…”

Resumo Objetivo: Avaliar a qualidade da identificação de triatomíneos na rede de laboratórios do estado de Pernambuco, Brasil. Métodos: Os nove laboratórios participantes receberam material de apoio com as chaves dicotômicas e um painel composto por sete insetos triatomíneos conhecidos no estado, para identificação da situação do espécime no recebimento (estrutura completa ou danificada), espécie e sexo. Resultados: Nove laboratórios de 12 aderiram ao estudo. A proporção de acerto para identificação do sexo foi de 56/63, e para espécie, 45/63, não apresentando relação direta com a ocorrência de danos nas estruturas morfológicas durante o transporte dos insetos. Para Panstrongylus megistus, houve acerto em todos os espécimes (9/9), enquanto para espécies do gênero Rhodnius a proporção foi menor (3/9). Conclusão: Apesar do bom desempenho na identificação entomológica, as fragilidades observadas poderão orientar ações para melhoria na rede de laboratórios e serão essenciais para os programas de controle vetorial da doença de Chagas.

“…As such, EQA is an essential tool for laboratory quality improvement, and most of the laboratory accreditation programs require EQA participation [7]. EQA helps laboratories recognize and resolve procedural weaknesses, and instills trust in the staff [8]. In 53% of Mediterranean countries (including France, Italy, and Turkey), the participation in EQA is mandatory by law, 29% of countries have guidelines for the scientific society, and, in 6% of countries (e.g., Greece), this is required by social security organizations for reimbursement of test costs [9].…”

External quality assessment (EQA) is a commonly used tool to track the performance of laboratory tests. In Korea, EQA participation is not mandatory, and even basic data about EQA participation are not available. We used data of a 10-year period extracted from two databases (2009–2018): (1) the database of the National Health Insurance Service to calculate the number of medical institutions that claimed health insurance benefits, and (2) the database of the Korean Association of External Quality Assessment Service to calculate the number of medical institutions participating in EQA. The proportion of institutions that made claims for the performance of laboratory testing throughout the 10 years were 73.6%–76.0% for clinics, 91.9%–97.5% for long-term care hospitals, 97.9%–99.5% for small to medium hospitals, 99.6%–100% for general hospitals, and 100% for tertiary hospitals. The mean EQA participation rate of institutions that performed laboratory testing for the 10 years was 1.9% for clinics, 3.1% for long-term care hospitals, 27.7% for small to medium hospitals, 96.6% for general hospitals, and 100% for tertiary hospitals. The mean EQA participation of clinics, long-term care hospitals, and small to medium hospitals are increasing but is still not sufficient. Regulatory approaches are needed to increase participation rates. This result would be used for health policymaking on the quality improvement of laboratory tests.
