Clinical medicine

Clinical medicine is the practice of diagnosing, treating, and preventing disease through direct patient care. It represents the intersection of medical science and compassionate healthcare delivery, where scientific knowledge meets the art of healing. The importance of clinical medicine lies in its direct impact on human lives—alleviating suffering, extending lifespans, and improving quality of life through evidence-based interventions tailored to individual patients.

“The good physician treats the disease; the great physician treats the patient who has the disease.” — William Osler
