ABSTRACT
Introduction: the purpose of every quality control laboratory for the serological diagnosis of syphilis is to monitor the accuracy of test performance.Objective: to evaluate the proposal of a statistical model to tabulate the results of the laboratories involved in the quality control of the veneral disease research laboratories-rapid plasma reagin serology for the assessment of and customized attention to them.
Methods: a model for the collection of information from the 21 laboratories of Villa Clara's provincial network in the 2006-2010 period was designed and refined until the final version was reached. The defined variables comprised Number of sent sera, Total discordant, Nonreactive Discordant, Reactive Discordant, Shipping by month and Final evaluation were defined. Evaluation criteria were set for each variable. This paper presented the evaluation of the model with information from January to March, 2011.
Results: the suggested model allowed the detection of the main difficulties such as the non-compliance with the number of sent sera, non-reception of samples monthly and also current conflicting results. The model is fair when making evaluation, since it uses generalized quantitative criteria that enable individualized qualitative assessment and it is also in line with current evaluative techniques applied in different fields of social endeavor.
Conclusions: the statistical model allows provincial quality control laboratory to tabulate data by using the suggested variables and thus evaluate each laboratory in Villa Clara.
