Internal audit in a microbiology laboratory

Abstract

Aim: To set up a programme of internal laboratory audit in a medical microbiology laboratory.

Methods: A model of laboratory based process audit is described. Laboratory activities were examined in turn by specimen type. Standards were set using laboratory standard operating procedures; practice was observed using a purpose designed questionnaire and the data were analysed by computer; performance was assessed at laboratory audit meetings; and the audit circle was closed by re-auditing topics after an interval.

Results: Improvements in performance scores (objective measures) and in staff morale (subjective impression) were observed.

Conclusions: This model of process audit could be applied, with amendments to take local practice into account, in any microbiology laboratory.
