ABSTRACT
The process of diagnosis is modeled on the scientific method of inquiry, which is largely viewed as an analytical process using logic and objective reasoning, and is therefore expected to be reproducible and highly accurate. Doctors gather evidence and apply diagnostic tests to come to a final conclusion or answer—the diagnosis. This model would lead one to think that clinical problems are simply an interaction of a disease state with provider(s) and the healthcare system. Each patient has his or her own unique combination of conditions, manifestations of illness, and personal response to them: the ability to recognize the need for a medical evaluation, seek and find appropriate care, and engage the healthcare system may largely dictate the efficiency and accuracy of the diagnostic process. There are many approaches to improving the patient's role in diagnosis. From a public health perspective, efforts to inform and educate the public can promote awareness of early warning signs of disease.
