Islamic hospitals also brought about the idea of separate wards or segments of the hospital that were separated by patient diagnostic. When Islamic hospitals first brought this about, not only were the wards separated by diagnostic but by sex as well. While hospitals today are not as strict and do not separate by sex anymore, they still separate people by disease or problem. By doing so, different wings could specialize in certain treatments specific to their patient. This practice not only still exists today in modern hospitals but also lead to the advancement of treatments back then that now comprise the “Canon of Medicine.” This separation of diseases not only helped the timely treatment of patients but also helped the patients and physicians from getting sick with other diseases that surrounded them because they only had to worry about the prevention of one disease. By separating patients, the specialization of certain wings and treatments really advanced the medicine and improved the efficiency of hospitals ultimately leading to how modern day hospitals are designed.
