임상미생물 검사 신빙도조사 결과보고(1999)

초록

Two trials of external quality assessment for clinical microbiology laboratory were pеrfromed in 1999. A total of ten specimens were distributed. Five specimens were distributed to 219 laboratories with 202 returns in Trial I and five specimens to 222 laboratories with 199 returns in Trial II. The percentages of fully correct identification of S. aureus, M. luteus, S. bovis, E. coli, P. aeruginosa, P. vulgaris, S. aureus, E. gallinaruт, K. pпeиmoniae, S. marcescens, and P. aeruginosa were 98.0%, 18.8%, 48.5%, 98.5%, 95.5%, 95.5%, 97.0%, 35.7%, 98.0%, 97.5%, and 89.0%, respectively. The acceptable percentages on disk-diffusion antibacterial susceptibility tests against oxacillin and vancomycin of S. aureus (MB9901) in Trial I were 96.8% and 86.6%, respectively. Those against ampicillin and gentamicin of E. coli (MB9903) were 87.7% and 88.5%, respectively. Those against piperacillin and tobramycin of P. aeruginosa (MB9904) were 77.9% and 88.8%, respectively. Those against cephalothin and amikacin of P. vulgaris (MB9905) were 34.3% and 100%, respectively. In Trial II, the performance on antimicrobial susceptibility showing more than 90% as acceptable percentages was improved except that (63.5%) against vancomycin of E. gallinarum and that (58.6%) against imipenem of S. marcescens.
