We report the results of a pilot study assessing the use of digital 'virtual slides' in haematological quality assessment. Conducted together with the UK National External Quality Assessment Scheme for General Haematology, the study involved 166 separate participants, using the format of a typical assessment exercise. The results revealed substantial concordance of observations made using digital slides with those reported in previous glass slide surveys that used identical cases. Participant feedback strongly supported the use of electronic slides in teaching and assessment roles. Our results suggest roles for this new electronic resource in external quality assessment (EQA), education and continuing professional development.
