The healthcare system uses structured steps for diagnosis. This foundational approach ensures doctors accurately diagnose patients, minimizing errors. This is because cases of failure to diagnose, misdiagnosis or delayed diagnosis often lead to serious consequences.
Here is the process physicians in the U.S generally follow to provide a diagnosis:
Initial evaluation and history
When a patient has concerning symptoms, a doctor will perform an initial evaluation by interviewing them to get more information about their symptoms. Asking open-ended questions is crucial at this stage.
The doctor will also obtain details about the patient’s past, family and social history (PSFH). They will review the patient’s past medical history, medical events in the family and past and current lifestyle, such as substance use, work environment, housing conditions, physical activity, education level and nutrition.
Physical exam
Once the doctor has enough information, they will conduct a physical exam by observing the patient’s demeanor, checking vital signs and examining body systems. Several techniques are used during a physical exam, including observing, touching, tapping and listening with a stethoscope.
Diagnostic testing
The diagnostic stage involves repeated information gathering, integration and interpretation. Based on data collected during the physical exam, the doctor will create a list of potential diagnoses and then order laboratory work (blood tests, urine tests and imaging, such as X-rays, CT scans, MRI and ultrasound) to confirm and rule out illnesses.
Interpretation
The doctor will interpret all findings to establish a diagnosis and, in turn, determine treatment. They can seek additional expertise by collaborating with other physicians or referring the patient to another doctor for advanced testing or to access specialized expertise.
The diagnostic process in the medical field significantly improves patient safety and outcomes. If you sustained an injury because your doctor made a mistake, consider legal guidance to protect your rights.
