The results of this study showed that interaction in this hospital was unexpected for both patients and their families. This unexpected interaction has four characteristics: unequal, unprofessional, instrumental, and non-cooperative. All of these themes indicate that DPI in these cases not only are not in direction of responsibilities and ethics of medicine but also are in contrast of it, specifically unprofessional and instrumental characteristics. They do not have a clear understanding of the treatment process and also cannot predict the doctors’ reaction. Despite the fact they know that the asymmetrical power reaction is not an appropriate interaction, they cannot do anything about it. Doctors do not participate in any active conversation with patients; they do not even allow them to participate in the interaction. This shows how doctors ignore their professional duties and ethics where patients are concerned.
The results of other studies have confirmed our findings. According to Mishler, medicine has its own voice, which is in contrast to the lifeworld voice of patients. The medical voice also has its own specific terminology that uses physical symptoms descriptions, which are based in a biomedical model, which focuses on a technical explanation of the body. This technical interest is incompatible with the patients’ lifeworld. Because patients’ lifeworld is a lived experience that is dependent on interaction, this instrumental form does not satisfy them (
19). A biomedical model has also been successful in practice; hence, it has dominated patients' life world. Theory of Mishler can explain three themes of our findings: unequal, non-cooperative and instrumental. On the other hand, studies of Silverman (
20) Atkinson (
21) and Barry et al. (
22) showed that medicine has more than one voice. However, it is unimportant to determine how many voice does medicine have; the only important point is that medicine has an instrumental and technical voice, which is not acceptable by the patient’s lifeworld. In the past four centuries, this voice has been successfully developed in a manner to allow it to become a dominant voice. Unequal, non-cooperative, and instrumental characteristics are related to the domination factor.
In continuation, DPI in our study was heavily dependent on modern medicine discourse, which is phrased in Haberma’s view as expert discourse (
10) and lauded in Foucult’s view as medical knowledge-power discourse (
11). Therefore, the quality of DPI is entirely dependent on the quality or grade of discourse. In any DPI, if the discourse is more dominant, the patient’s dissatisfaction will be greater, which is directly related to the existing asymmetrical power relationship. The patients in our study realized that the doctors’ interactions with them were unprofessional. However, a majority of them did not file a complaint. This shows the hegemonic feature of DPI, which suppresses the patient in the worst way. A big part of the reason goes back to the formation of modern medicine discourse.
In the context of our study, one of the reasons for this type of DPI is a weakness of the medical structure. Although unequal, non-cooperative and instrumental are the general characteristics of medicine in the world, but unprofessional interaction is unacceptable and needs to be further discussed. The question also remains why these physicians approach treatment by neglecting some observation protocols? It seems that this action is partially related to underlying weakness in the medical structure to control and supervise their behavior, so instead, they do as they please. Due to this situation, the diverse forms of domination and suppression were identified in this context (
23,
24). We suggest further study in order to determine why this occurs.
Finally, there are two forms of doctor-patient relationships: socio-emotional and task-oriented. In the socio-emotional model, there is intrinsic communication, interpreted affect, linking, and a satisfactory relationship between the doctor and patient. A task-oriented model involves question-asking, information-giving, counseling, management, and treatment approaches by doctor and question-asking, full, accurate report of medical symptoms and history approach by patient (
25). Our findings showed that DPI in the context of our study was neither similar to these two types. There was no active question-asking communication or other features which were mentioned above. In the study of Barry et al. (
22), it was shown that the quality of interaction is dependent on the quality of using voice of medicine or the lifeworld. Our findings indicated that the voice of the lifeworld did not have any place in DPI. However, because good doctor-patient interactions are closely related to quality of care (
26), policymakers should pay attention to the promotion of DPI. In this approach, a patient-centered model can be effective (
27).
5.1. Conclusion
In the context of our study, DPI contains a hegemonic feature that is unacceptable for patients. In this situation, the interaction is unequal, unprofessional, instrumental, and non-cooperative. Therefore, the patients’ lifeworld is suppressed by the doctor-centered condition. Patients do not have a clear understanding of interactional processes. The interaction is completely dependent on the personal behavior of the doctor and not his/her professionalism. Because DPI has an important role in medical care, policymakers must therefore establish suitable structures based on patient-centered approaches. Further qualitative and quantitative studies are suggested.
5.2. Limitations
The biggest limitation was concerning participant observation. Because the researcher hid his role as researcher, it was a problematic situation based on ethical issue. However, we did not have an alternative approach to gather these data. Another limitation was that even though the severity of the patient illness and disease may have had an effect on the DPI, we could not categorize the patients according to their severity of illness.
