RESUMO
FUNDAMENTO: la utilización del Programa de Evaluación Externa de la Calidad (PEEC) para laboratorios clínicos, son actualmente un requisito indispensable en su proceso de acreditación. La participación y el desempeño aceptable en estos programas, cumplen una función de mejora en la práctica de los laboratorios clínicos y educan sobre los beneficios y limitaciones de los procedimientos analíticos. OBJETIVO: demostrar la utilidad de la evaluación de la veracidad para detectar los laboratorios que desvían la media consenso, aumentan la dispersión y causan falsos resultados en la evaluación. MÉTODOS: se realizó un estudio observacional descriptivo, longitudinal y retrospectivo para evaluar la veracidad desde el año 1999 al 2013, para ello se procesaron las muestras de los 64 laboratorios asistenciales de la provincia y de forma paralela en el laboratorio de referencia del Centro Coordinador del PEEC, se consideraron aceptados los valores comprendidos en el rango ± 3 desviaciones estándar y rechazados, los que están fuera de rango. RESULTADOS: la veracidad mejoró en el tiempo en los laboratorios de ambos niveles de atención con excepción de los componentes de uratos y conteo global de leucocitos que disminuyó debido a dificultades de equipos, reactivos o procedimientos. CONCLUSIONES: en catorce años de aplicado el programa en la provincia se ha obtenido un promedio de 74 % de resultados aceptados demostrando que el sistema propuesto es eficaz y beneficioso.
BACKGROUND: the use of the Program of External Quality Assessment (PEQA) for clinical laboratories is nowadays an indispensable requirement in its accreditation process. The acceptable participation and performance in these programs act as an improvement in the practice of clinical laboratories and instruct about the benefits and limitations of the analytic procedures. OBJECTIVE: to demonstrate the usefulness of the assessment of accuracy to detect those laboratories that deviate average consensus, increases straying and cause false results in the evaluation. METHOD: a retrospective, longitudinal, descriptive, observational study was conducted to assess accuracy from 1999 to 2013. Samples from the 64 clinical laboratories in the province were processed; in parallel, values included in the level ± 3 standard deviations and rejected (which are out of the level) were considered "accepted" in the reference laboratory of the Coordinating Center of the PEQA. RESULTS: accuracy improved in time in the laboratories in both levels of attention with the exception of the urate components and leukocyte overall count, that decreased due to difficulties with equipments, reagents or procedures. CONCLUSIONS: during the 14 years of the application of the program in the province, an average of a 74 % of accepted results has been obtained demonstrating that the system proposed is efficient and beneficial.

BACKGROUND: The purpose of this study is to better characterize the hematological, biochemical, respiratory, cardiovascular and electroneurophysiological parameters in young adult Cercopithecus aethiops sabaeus of both sexes. The rhesus and cynomolgus monkeys are widely used as experimental primate models. However, only few articles have been published testing toxicological effects of pharmaceuticals on African green monkey. METHODS: The present study was carried out with the recompilation of all parameters recorded before the first drug administration in five sub-chronic or chronic toxicological studies performed on 66 Cercopithecus aethiops sabaeus, born in Cuba. RESULTS: This study provides hematological, biochemical, respiratory, cardiovascular and electroneurophysiological data for both choosing animals to be included into experiments and monitoring these parameters during the study. CONCLUSIONS: We conclude that this study provides valuable integrated data for determining the health status, including electroneurophysiological parameters, data not previously reported for this species, of the African green monkey.
