347 Finnish deck officers completed the questionnaire on medical training, knowledge and skills. The following conclusions could be drawn: a. Medical training must be based on generally accepted standards, both nationally and internationally. b. More practical exercises should be included in the training. c. Refresher medical training clearly increases knowledge and skills but it also gives the possibility to train, maintain and repeat practical routines. d. Evaluation of the skills should be a part of qualification. e. Good medical knowledge on board ship needs radio-medical services and vice versa.
