Abstract

Con el objetivo de evaluar el desempeño laboratorial de las unidades de atención primaria (UAP) en el diagnóstico de tuberculosis por baciloscopía en Pelotas, Brasil, se realizó un estudio descriptivo en el cual se incluyó todas las baciloscopías solicitadas en once UAP entre 2007 y 2010. Para la evaluación del desempeño laboratorial se cuantificó el número de baciloscopías solicitadas y el tiempo entre la solicitud y la lectura de la lámina de examen en el laboratorio de referencia. Se encontraron 477 solicitudes registradas en las UAP. De ese total, apenas 51,8% fueron encontradas en el libro de registro del laboratorio, el desempeño más bajo fue de 24,2% y el más alto de 71,4%. Se identificó, en relación al tiempo de lectura de las láminas, que el 27,7% de las lecturas demoraban 8 días o más. Se concluye que las UAP evaluadas de la ciudad de Pelotas tienen un bajo desempeño laboratorial en el diagnóstico de TB por baciloscopías.

Translated abstract

In order to assess laboratory performance of Primary Care Units (UAP, Spanish acronym) in TB diagnosis though the sputum smear test in Pelotas, Brazil, a descriptive study was completed which included all sputum smear tests requested at eleven primary care units from 2007 to 2010. To assess laboratory performance, the number of sputum smear tests requested was quantified as well as the time between the request and the reading of the glass slides at the lab. 477 requests were registered at UAP. Of this total, only 51,8% were found in the laboratory’s record book, the lowest performance was 24,2% and the highest 71,4%. Regarding the reading of glass slides, it was determined that 27,7% readings took 8 days or more. It is concluded that the primary care units in Pelotas have a low laboratory performance in TB diagnosis by sputum smear tests.

The quality of care. How can it be assessed?

A Donabedian (1988)

Before assessment can begin we must decide how quality is to be defined and that depends on whether one assesses only the performance of practitioners or also the contributions of patients and of the health care system; on how broadly health and responsibility for health are defined; on whether the maximally effective or optimally effective care is sought; and on whether individual or social preferences define the optimum. We also need detailed information about the causal linkages among the structural attributes of the settings in which care occurs, the processes of care, and the outcomes of care. Specifying the components or outcomes of care to be sampled, formulating the appropriate criteria and standards, and obtaining the necessary information are the steps that follow. Though we know much about assessing quality, much remains to be known.
