Al-Nahdi has a center for preventive health services. An important goal of Al-Nahdi was to offer programs that would encourage members to stay healthy. Various programs already had been planned, including those on smoking cessation, proper nutrition, diet, and exercise. The clinic portion of the health center would be quite large; however, certain constraints in the layout would be necessary. Acutely ill patients would need to be separated from well patients. In addition, the radiography department cannot be adjacent to the main waiting room. It is very important to minimize the walking distance for both the patients and Al-Nahdi personnel. The matrix below provides the expected flow between departments based on 35 patients per day.
