It is important to establish standards for the competence of professionals working in mammography screening programmes. This recommendation determines if mammography readers should read a specific number of mammograms.
Should an optimal number of readings vs. no specific number be used for allowing mammography readers to work in mammography screening programmes?
The ECIBC's Guidelines Development Group (GDG) suggests that mammography readers read between 3500 and 11000 mammograms annually in organised mammography screening programmes.
Conditional recommendation for the intervention
Very low certainty of the evidence
Considerations for implementation and policy making
This optimal range should be implemented as part of screening programmes that use double reading, as double reading of mammograms will improve the overall quality of the reading.
Efforts to provide support with centralised reading may help implementing this recommendation.
The number of readings should be averages over longer periods and use appropriate sampling for this measurement.
The GDG recognised that local circumstances of the individual's performance will affect the quality of readings as much as the number of readings.
1. More published evidence is required which could also come from good monitoring data.
2. Further research on elements that may influence results such as: when to read during the day, how many mammograms to read per day, time needed and variation of time for readings between readers, relationship between breast cancer detection and false positives, comparison between those reading only screening mammograms and those doing screening and clinical/diagnostic mammography.
3. More research on types of training for mammography readers.
4. Research into the role of artificial intelligence in double reading.
Monitoring and evaluation
The suggested range applies to mammography screening, not digital breast tomosynthesis.
Programmes should continue to monitor the number of readings by readers and the quality indicators of the reading process.
