It shows how factors such as language, sex, gender, religion and the register of medical practice affects diagnosis, recommendations and the rendering of care. Because of the location of the area of study, and the seeming language diversity of both the workforce and patients in ABUTH, the problem of effective communication arise. ABUTH is located in a predominant Hausa community in Shika yet English language or un-standardized version of Hausa is mostly used for diagnosis. This problem is made worse by the use of Medical language in the encounter that takes place between doctors-patients.
