This article focuses, from an original angle, on the issue of high blood pressure (hypertension) which represents a major public health challenge in Haiti, particularly in Cap-Haitian, with low normalization despite drug treatment. Lack of family support at the hospital and non-compliance with medical recommendations often contribute to this problem. Furthermore, in the Haitian hospital environment, health professionals place much more emphasis on the physical aspect while ignoring that health involves a biopsychosocial dimension. To carry out this study, we adopted a qualitative approach. With this in mind, three patients, including two women and one man, were recruited. Their age ranges between 40 and 60 years old with a predominance of participants from privileged backgrounds. Semi-structured interviews made it possible to assess compliance with treatment and the quality of the family environment. One of the participants presented poor compliance, highlighting the significant impact of the quality of the family environment on compliance with treatment. The results indicate better compliance among patients from advantaged backgrounds, highlighting the importance of psychological support and compliance with medical recommendations. The findings of this research call for further integration of the family approach into hospital treatment of hypertension to improve therapeutic effectiveness and promote positive outcomes.
