Knowledge sharing among doctors at a teaching hospital in addition to a routine activity that is always executed, can also serve as a forum for updates and sharing new things with colleagues in particular with regard to medical treatment. The success and sustainability of shared knowledge can be seen from three aspects, namely the level of effectiveness, an increase in the ability of cross- training among doctors and interaction frequency effect on the sharing of knowledge among doctors. This study aims to produce a matrix that can be used to perform mapping on the current state of knowledge sharing activities that took place, especially in teaching hospitals in Indonesia. This study uses a survey conducted from 2010 through 2014 to five teaching hospitals in Indonesia. The resulting matrix has managed to give a preliminary picture of the influence of the ratio of the number of resident and consultant in a department of the effectiveness of knowledge sharing, cross- training and capacity building is also interaction frequency. The hope is that with this matrix will encourage decision makers in a hospital to better reconsider resident and consultant recruitment process as well as the ratio of the number of both to obtain good quality medical treatment.
