DECISION TREE FOR NEUROLOGICAL AND MUSCULOSKELETAL DISORDERS

Sample Solution

Patient Case Study: Patient: 55-year-old male with a history of hypertension, hyperlipidemia, and type 2 diabetes mellitus. Chief Complaint: Progressive weakness and numbness in the left arm and leg over the past 6 months. Decision 1: Order an MRI of the brain and cervical spine. Rationale: The patient's symptoms are concerning for a neurological disorder, such as a stroke, multiple sclerosis, or a tumor. An MRI is the most sensitive imaging modality for detecting these disorders. Evidence-Based Literature:

• A study published in the journal Neurologyfound that MRI is the most sensitive imaging modality for detecting brain tumors, with a sensitivity of 95%.
• A study published in the journal The Lancetfound that MRI is the most sensitive imaging modality for detecting multiple sclerosis lesions, with a sensitivity of 85%.

Decision 2: Start the patient on a course of corticosteroids. Rationale: Corticosteroids can help to reduce inflammation and swelling in the brain and spinal cord. This can help to improve the patient's symptoms and prevent further neurological damage. Evidence-Based Literature:

• A study published in the journal The New England Journal of Medicinefound that corticosteroids were effective in improving the symptoms of multiple sclerosis.
• A study published in the journal Strokefound that corticosteroids were effective in reducing the size of brain tumors.

Decision 3: Refer the patient to a neurologist. Rationale: A neurologist is a specialist in the diagnosis and treatment of neurological disorders. The neurologist will be able to perform a comprehensive evaluation of the patient and determine the cause of their symptoms. Evidence-Based Literature:

• A study published in the journal The Journal of the American Medical Associationfound that patients who were seen by a neurologist within 24 hours of experiencing a stroke were more likely to have a good outcome.
• A study published in the journal Multiple Sclerosisfound that patients who were seen by a neurologist early in the course of their disease were more likely to have a better quality of life.

Co-Morbid Physical Factors: The patient's history of hypertension, hyperlipidemia, and type 2 diabetes mellitus are all risk factors for atherosclerosis. Atherosclerosis is a condition in which plaque builds up in the arteries. This can lead to narrowing of the arteries and reduced blood flow. Reduced blood flow to the brain can cause a stroke. Patient Factors: The patient's age is also a risk factor for neurological disorders. The risk of stroke increases with age. Additionally, the patient's history of smoking is a risk factor for multiple sclerosis. Expected Outcomes: The expected outcomes of the decisions I recommended are:

• The MRI will provide a definitive diagnosis of the patient's neurological disorder.
• The corticosteroids will help to reduce inflammation and swelling in the brain and spinal cord. This can help to improve the patient's symptoms and prevent further neurological damage.
• The neurologist will be able to develop a treatment plan for the patient's neurological disorder.

Actual Outcomes: The actual outcomes of the decisions I recommended were:

• The MRI revealed a brain tumor.
• The corticosteroids helped to improve the patient's symptoms.
• The neurologist recommended surgery to remove the brain tumor.

Differences Between Expected and Actual Outcomes: The main difference between the expected and actual outcomes was the diagnosis of a brain tumor. The MRI revealed a brain tumor that was not suspected based on the patient's symptoms. However, the corticosteroids were still effective in improving the patient's symptoms. The neurologist recommended surgery to remove the brain tumor. This is the standard treatment for brain tumors. Conclusion: The decisions I recommended for the patient were supported by the evidence-based literature. The MRI was the most sensitive imaging modality for detecting the patient's brain tumor. Corticosteroids are effective in reducing inflammation and swelling in the brain and spinal cord. A neurologist is a specialist in the diagnosis and treatment of neurological disorders. The decisions I recommended helped to improve the patient's symptoms and prevent further neurological damage.
