Background:
Moulages can greatly extend the possibilities of simulation in teaching and assessment. Since moulages that fit an educator's exact needs are often unavailable commercially, this paper explains how 2-dimensional transfer tattoos can be independently developed, produced, and evaluated.
Methods:
From representative photographs of the specific skin condition an analogue copy of the pathological finding is drawn. Once validated by the medical expert, it can be digitized by scanning and processed using graphics software. The final digital image file is printed onto transfer paper. Once applied and fixed onto the intended wearer, usually a simulated patient, its authenticity can be confirmed, and further transfer tattoos can be produced.
Results:
Using this moulage technique we produced 10 different 2-dimensional transfer tattoos to date, including hematoma, Janeway lesions and splinter nails. These moulages are used in clinical skills training, formative and high-stakes summative assessment in undergraduate medical and nursing programs.
Conclusions:
By sharing our development process for 2-dimensional transfer tattoos, health profession educators can produce their own that best fit their local educational needs. Due to their high authenticity and standardization, 2-dimensional transfer tattoos are ideal for use in high-stakes assessment.
