title: [The pilot program in Mexican clinical laboratories. I. The characterization of structure and productivity].
abstract: OBJECTIVE
  To validate a questionnaire which evaluates the structure of clinical laboratories and to obtain information on its productivity.
  
  
  METHODS
  A group of 18 laboratories belonging to hospitals of second (N = 15) and third (N = 3) levels of health care. Fifteen participants belong to the public sector and three are first rate private institutions. They are located in the metropolitan area of Mexico City comprising the Federal District (N = 12) and the State of Mexico (N = 6).
  
  
  METHODS
  The questionnaire has 12 items which received a 0, 1/2 or 1 score. The maximum possible score for a perfect laboratory as well as for any question is 100. The questionnaire was filled during a visit to the participating hospitals by auditors of the agency of the Ministry of Health in charge of licensing laboratories at a national level. Information covering six months of work was obtained to calculate productivity using number of tests per worker per month.
  
  
  RESULTS
  The global score of the 18 participants was 49. The private ones had the highest scores (79 to 96) which was to be expected as they were selected for their high technical and human resources. The five State laboratories had a score above the global mean, but only one of the Federal ones was in this situation. A high interlaboratory variability was observed, i.e. productivity in the highest rated was nine times larger than in the lowest rated. This finding suggests the presence of interlaboratory differences in the criteria used in the collection of productivity information.
  
  
  CONCLUSIONS
  This short questionnaire can be used as a first approximation to identify structure deficiencies of the Mexican clinical laboratories.
