In healthcare institutions, communication between the caregivers themselves and between them and the patients and / or their patients are problematic. The purpose of this article is to indicate the proportions of physicians and nurses stressed because of communication problems in the health institutions of the City of Lubumbashi, DRC. To achieve this, a stratified proportional sample of 562 subjects (n = 562), including 432 nurses and 130 physicians allowed to collect data by questionnaire. These were encoded in Microsoft Excel and analyzed via Epi Info 7.2 of 2016 and SPSS 19.0 of 2012. The chi–square test helped to test our hypothesis, considering the odds ratio (OR) in the confidence interval (IC) of 95% and the value of p to guide the interpretation. Doctors and nurses stress at 49.28% in their communication exchanges with their colleagues, at 49.82% in communication with their respective hierarchies, at 59.43% in communication with patients and at 60.32% in communication with their guides. In the communication modes, the gestural mode and the verbal mode are stressful in the interactions with colleagues (94.39%), the hierarchical leaders (88.18%), the patients (99.03%) and their guides (99, 37%). These results concur to note that the relational framework of surveyed physicians and nurses is traversed by problematic interactions, often conflicting between professionals and even with the hierarchical leaders that between the caregivers and, especially, the patients and their escorts.
