This study aims to determine the therapeutic itinerary of patients followed for connectivitis in the Internal Medicine Department of the CNHU HKM of Cotonou. <strong>Methodology:</strong> This is a cross-sectional study that included patients followed for connectivitis in the HKM-Cotonou Internal Medicine Department from January 2010 to October 2018. <strong>Results:</strong> Out of 3600 patients hospitalized in the study period, 21 had connectivitis, <i>i.e.</i> a hospital frequency of 0.58%. Of the 21 patients collected, 18 met the inclusion criteria. The mean age was 40 (±11) years old and the youngest was of 21 and the oldest 58. The sex ratio was 17.9. The “Fon” ethnic group was the most represented (33.3%) and 15 (83.3%) subjects were Christians. Systemic lupus erythematosus was the most frequent connectivitis (55.6%). The average time of consultation was 38 months. Witchcraft was the most incriminating cause (78%). Ten (55.5%) patients had resorted to self-medication as their first choice of treatment, 5 (27.8%) to traditional medicine treatment and 3 (16.7%) to prayer for healing. The reasons for the first choice of treatment were satisfaction (44.4%), financial problems (27.8%), trivialization of the disease (16.7%), and advice from family and friends (11.1%). The consultation at the CNHU followed a referral from a first contact health structure (61%) or an initiative of the patient (27.8%). <strong>Conclusion:</strong> Connectivitis is a source of diagnostic error in our context. Awareness must be raised among patients for an early consultation at the first symptoms.展开更多
