title: Quality assurance in clinical laboratories in Taiwan.
abstract: OBJECTIVE
  In 1994, the Taiwan National Health Administration assigned the execution of a quality assurance (QA) survey program to the Association of Laboratory Medicine. The purpose of this program was to investigate the quality of clinical laboratory assessments and to promote QA in the fields of clinical microscopy, hematology, chemistry, microbiology, serology, and blood banking. We report the findings of QA surveys conducted in 1998 and the effect of voluntary training on improvement of clinical laboratory testing.
  
  
  METHODS
  A total of 1,008 clinical laboratories were included in the program in 1998. Proficiency testing (PT) was performed to evaluate various laboratory tests. Continuing education programs were conducted and experts visited laboratories that sought guidance before the PT was conducted. The full mark was set at a score of 100 for each PT scheme. The criterion for acceptability of PT results was set at a score of 80 or more.
  
  
  RESULTS
  The rates of acceptable results were 82.4% (607/736) for hematology, 57.4% (267/465) for blood banking, 69.3% (561/810) for chemistry, and 80.1% (321/401) for microbiology. The rates of acceptable microscopy results were 90.9% (509/560) for urine chemical tests and 84.6% (610/721) for others. The rates of acceptable serology tests were 73.3% (384/524) for hepatitis and 85.6% (441/515) for syphilis. The rates of acceptable performance differed significantly among clinical laboratories with different rankings: clinical laboratories at institutions classified below the level of district hospital showed comparatively poor performance. Laboratories that received guidance showed significant improvement in performance from 1997 to 1998.
  
  
  CONCLUSIONS
  A QA program is urgently needed in Taiwan to improve laboratory performance.
