Aim-To develop an internal quality assessment (IQA) scheme in a clinical bacteriology laboratory.
Methods-Over 24 months, 1230 diagnostic specimens, representing 0.42% of laboratory workload, were anonymised and resubmitted for analysis.
Six hundred and twenty one (48.7%) of these gave positive culture results; 44 fecal and upper respiratory specimens were « spiked » (artificially inoculated) to increase the proportion of positive samples.
Discrepancies between IQA and clinical sample results occurred in 188 cases (14.8%): 76.6% of these were in culture results, 13.3% in microscopy performance, and 10.1% in clerical recording.
