 Not only did these discoveries lead to lasting improvements in medicine in the Muslim world, but through the influence of early Islamic and Arabian hospitals, medical institutions around the world were introduced to various new concepts and structures, increasing the efficiency and cleanliness which can still be found in modern-day institutions.Some of these influential concepts include the implementation of separate wards based on disease and gender, pharmacies, housing of medical records, and the education associated with practicing medicine.Prior to the Islamic era, most European medical care was offered by priests in sanatoriums and annexes to temples.
