The doctor-patient relationship consists of a hierarchically asymmetrical dyad. One side cares and the other receives care, analogous to the attachment relationship. The doctor would have the attachment figure s role, being able to activate his or her caregiving system. The purpose of this study is to analyze how the care system is inserted in the doctor-patient relationship, analyzing the attachment style of the physician in addition to relating it to the care ability that the doctor has with his/her patient. Eleven hematologists from Rio de Janeiro and São Paulo with experience in SUS were interviewed using a semi-structured interview script and the self-report instrument AAS-R (Adult Attachment Scale-Revised) was applied. After content analysis of the interview and a cluster analysis of the AAS-R, all the doctors presented secure attachment, with avoidant-dismissing and avoidant-fearful defensive aspects. Four categories were also analyzed: personal experiences with medicine and/or hematology; hematology s specificity; how to deal with loss; and caring towards other. We concluded that the present it is important to prioritize the doctor s stance in the relationship, and to attend their psychological and relational needs. In that manner, interventions in the healthcare team can be proposed, providing the proper care to the healthcare professional, and, hence, improve their relationship with patients and their family members.
