Study Notes
Intuitive vs. Analytical Reasoning
- Intuitive reasoning is rapid, experiential, and uses pattern recognition. It relies on mental shortcuts, but is prone to bias and cognitive errors. Experts sometimes use it.
- Analytical reasoning is slower, controlled, and utilizes hypothetical-deductive processes. It involves acquired critical and logical thought, often for complex problems.
Heuristic Thinking and Bias
- Heuristic thinking is a problem-solving method using mental shortcuts or rules of thumb. It's useful when optimal solutions are impractical or impossible.
- Cognitive bias includes:
- Availability heuristic: Tendency to accept diagnosis based on ease of recalling similar past cases, instead of considering prevalence/probability.
- Anchoring heuristic: Tendency to fixate on initial impressions, despite new information.
- Premature closure heuristic: Diagnosing prematurely before fully evaluating all possibilities.
- Confirmation bias: Seeking to confirm initial impression/diagnosis, ignoring contradictory information.
- Framing heuristic: Decisions based on how information is presented, rather than the facts alone.
- Blind obedience: Over-reliance on objective measurements or authority.
Diagnostic Errors
- Common diagnostic errors include delaying diagnosis, giving the incorrect diagnosis, and missing a diagnosis. Distractions frequently contribute.
- Categories of diagnostic errors include: vascular events in older adults, infections, and cancers in adults.
- Differential diagnoses involve evaluating likely, less likely, and must-not-miss diagnoses, emphasizing history, subjective data, and physical exam.
- Illness scripts define features and discriminatory features for conditions to consider.
High-Value Screening
- High-value screening uses USPSTF recommendations, especially for patients with limited life expectancy.
- It considers potential downstream implications and emphasizes understanding test characteristics and the patient's goals.
Plain Radiograph (X-ray)
- X-rays use radiation absorbed by different body tissues; tissues absorb different amounts.
- X-rays are used to diagnose bone fractures, lung issues, and other conditions.
Indications for Chest X-ray
- X-rays are indicated for suspected infections, major trauma, and certain conditions requiring further investigation.
Checklist of Reading a Chest X-Ray
- Specific anatomy and views are evaluated when reviewing x-rays.
PA vs. AP View
- AP: Anterior-Posterior view, used for hospitalized or critically ill patients; preferred for children aged 3-7.
- PA: Posterior-Anterior view, used as a routine technique, involving the patient sitting while x-ray is taken (full inspiration).
Computed Tomography (CT)
- CT scans use narrow x-ray beams aimed at patients, quickly rotating around the body to produce cross-sectional images ("slices").
- Advantages include speed and detail. It's used in stroke-like symptoms, abdominal/thoracic/brain lesions, and for follow up on complex fractures/bone tumors.
Magnetic Resonance Imaging (MRI)
- MRI produces three-dimensional detailed anatomical images of soft tissues.
- Advantages include non-invasive nature, superior image quality, exceptional detail, and better visualization of soft tissues, blood vessels and abnormalities.
- MRI is useful for detecting brain tumors, vascular disorders, multiple sclerosis, and other neurological conditions; as well as for soft tissues and spinal/nerve conditions.
- Limitations include cost, time requirements for patient to remain still, concerns with metal implants.
CT versus MRI
- CT is useful for evaluating bone structure, whilst MRI is more versatile for evaluating soft tissues/organs.
- CT is faster, more cost effective, and more tolerant to patient movement; but MRI yields superior image quality regarding soft tissue/organ evaluation; this information is particularly relevant to cases with suspected malignant conditions.
Ultrasound
- Uses sound waves to produce images of internal body structures.
- It's safe in pregnancy, good for imaging soft tissues and fluid-filled structures (e.g., abdomen), diagnosing certain musculoskeletal conditions, and guiding needle biopsies.
Screening for Average-Risk Women
- Risk-based evaluation includes screening mammography and physical exams.
Thyroid
- Hypothyroidism: Subjective symptoms include fatigue, menstrual changes, dry skin/hair loss, cold intolerance, and depression. Objective findings may include heart bradycardia, dry skin, and thickened skin.
- Hyperthyroidism: Subjective symptoms include palpitations, mood changes, heat intolerance, osteoporosis, neck pain, or changes to the eyes. Objective findings may include tremor, anxiety, or rapid speech.
Abdominal and Pelvic Imaging
- Ultrasound and CT are used to assess potential appendicitis, other abdominal/pelvic issues, and related conditions, such as in suspected appendicitis in children or pain in the right upper quadrant.
Breast
- Screening for average-risk women includes regular (yearly or biannual) physical exams and mammograms.
- Patients who present with a breast mass require both ultrasound and mammogram.
Concerning Signs of Breast Cancer
- Signs of breast cancer include nipple inversion, discharge, discoloration, skin changes, asymmetry, and palpable masses.
- Additional observations and details about the lump (such as shape, texture, tenderness, mobility, and retraction/dimpling) are important in diagnostic testing.
Respiratory Tract Infection, Asthma, and Other
- Common causes include infections like pneumonia, and other respiratory issues.
- Appropriate imaging tests, such as x-rays, may be indicated to assess for certain conditions, including infections, or to determine the need to pursue treatment, when necessary.
Cardiovascular Conditions
- Conditions to treat or evaluate related to the heart can include stroke risk; or cardiac-related issues.
- Tests employed include electrocardiograms (EKG), Echocardiograms (ECHO), or cardiac CTs (or MRIs) in assessing for suspected cardiac conditions.
Orthopedic Issues
- Common orthopedic conditions to diagnose include fractures, osteoarthritis, tendonitis, and others.
- Ankle tenderness, and posterior/medial malleolus tenderness are key points to consider using the Ottawa Ankle Rules to assess the need to perform x-rays to diagnose suspected orthopedic conditions.
Neurological Conditions
- Conditions involving the nervous system can involve conditions such as stroke/TIA; migraine/vestibular dizziness/vertigo, or seizure disorders.
- Tests such as CT Angiography (CT-A), CT Imaging, MRI, or other procedures will be employed for assessing suspected neurological ailments.
Other Medical Conditions and Evaluation
- Other relevant medical conditions, such as renal/kidney disease, or infectious diseases like tuberculosis can sometimes be apparent in bodily fluids such as blood or urine samples.
- Appropriate testing may include urinalysis to identify abnormalities. Further investigation is important when there are abnormalities found in these samples.
