The field study aims to detect the importance and necessity of the in-service training, which is known to provide professional and personal development after graduation at every field of profession, in health sector and the approachesof  the physicians who provide primary health care on the issue. During  the  application  process,  a  field  study  was  conducted  through  an  online  survey  with  the participation of 4,034 primary care physicians working in Istanbul. 610 people participated validly in the study. The opinions, evaluations and expectations of the physicians about in-service training were measured.  In  addition,  it  was  tried  to  determine  the  knowledge  and  skill  levels  of  the  physicians  on these issues by determining the in-service training subjects that physicians deemed necessary for their professional and personal development. The study has three remarkable results. The first result is that physicians care about the in-service trainings be given in 1-2 hours courses, at least once a month, in a comfortable place such as a hotel and especially with practical methods. The second important result is that the number of physicians who believe that the training should be given by universities and that the trainings this way will contribute to professional and personal development constitute the majority. The third result emphasizes that even if the physicians participating in the study find their knowledge and skill levels about preventive healthcare and chronic diseases sufficient, they want to receive more education in this field
