Rapid rescreening of cervical smears as a quality control method.
The use of a rapid rescreening method as part of an internal quality control programme is reported. During a 12-month period 33,976 smears were reviewed (90.9% of total workload). Two-hundred and nineteen reports were altered, with 23 dyskaryotic smears identified, a false-negative rate of 0.07% a false-negative dyskaryotic rate of 1.7%. Smears reported as dyskaryotic were also subjected to the rapid screening method (with 86.8% correctly identified) as well as using the method to assess smears before the usual primary screen (with 67.2% of dyskaryotic smears correctly identified). Rapid rescreening as a quality control method is effective and although it has limitations, should replace 10% proportional rescreening as the preferred daily quality control method of choice.
