In the assessment of mucositis, the inter-evaluator variability needs to be minimised
and would likely to be best accomplished by training. The aim of this study was to
evaluate the effect of training on concordance of evaluators in scoring oral mucositis.
The evaluators were informed about the pathobiology and clinical appearance of mucositis
and were trained in scoring mucositis according the Oral Mucositis Assessment Scale
(OMAS). The effect of the training was evaluated by a pre- and post-training test.
Each test consisted of 15 slides depicting oral mucositis. The pre- and post-training
scores were compared to the reference standard. During 8 months at 6 meetings, 65
evaluators were trained. The mean percentage correctly scored slides according the
OMAS increased significantly between the pre- and post-training test (P<0.001). Training
evaluators in scoring oral mucositis has a significant improvement on the outcome
of mucositis assessment.
