MAZZA, Mariana et al. Effectiveness of the National Quality Control Program in Mycology of Argentina and performance evaluation of participating laboratorios. Rev. argent. microbiol. [online]. 2021, vol.53, n.2, pp.21-30. ISSN 0325-7541.

The National Quality Control Program in Mycology (PNCCM) of Argentina was establishedin 1996 to improve the quality of the mycological diagnosis, to help establish and to setup standardized procedures and continuous training of laboratory staff. The aim of this studywas to assess the effectiveness of the PNCCM in the 1996---2018 period. Data from the NationalMycology Laboratory Network (NMLN) and PNCCM database was used to estimate the increasein the number of controlled laboratories and jurisdictions, the percentage of participation, theimprovement in the quality of results and the adherence to the program. Satisfaction surveyswere performed to assess user satisfaction. The number of controlled laboratories increasedfrom 29 to 146; participation increased from 49% to 93% and general adherence was 72% inthe evaluated period (1996---2018). Improvement in the quality of the results was 15% for lowcomplexity samples; 7% for intermediate complexity samples and 14% for the identification ofhigh complexity strains. Up to 84% of the users consider the PNCCM to be ‘‘very good’’ and 16%‘‘satisfactory’’. These results show the importance of the PNCCM, which is widely accepted bymycological diagnostic laboratories from Argentina.
