Patient–doctor interactions around alternative and complementary medicine in the context of oncology care in a Latin American country

Objective: To characterize doctor-patient communication patterns around the use of complementary and alternative medicines (CAM) in the context of oncology care in Colombia. Methods: A qualitative study was conducted using snowball sampling until data saturation was reached. We included oncology specialists and cancer patients who were in active treatment. Semi-structured interviews were conducted following a guide designed for each group of participants. An analysis based on open coding was performed to identify thematic areas. The coherence of emerging categories was verified by contrasting the data set within the content of the participants’ reports and existing literature. Results: In total, 10 oncologists and 16 cancer patients were included, representing diverse professional fields and cancer diagnoses, respectively. Communication patterns comprise themes regarding the beginning of the interaction (i.e., patient's anticipations), the patient–doctor relationship (i.e., confidence), the characteristics of the message (i.e., synthetic vs explanatory), the communication styles (i.e., confrontational vs conciliatory), and the closing of the interaction (i.e., continuity vs. end of communication). In addition, extrinsic factors influencing communication were found to be related to participants (i.e., knowledge, cultural background) and context (i.e., institutional procedures). Conclusions: The low frequency of communication contrasts to the increasing use of CAM. Divergent perspectives between doctors and patients could limit shared decision-making on the use of CAM. Enhanced knowledge and education on CAM for both actors is fundamental to improve their interaction and to move away from paternalistic and confrontational communication, particularly in a world region with cultural backgrounds that influence the use of CAM.
