- Differential Diagnosis
- Related: Clinical Reasoning, Diagnostic Error
A systematic process of listing and comparing possible conditions that could explain a patient's symptoms, then using evidence to narrow the list toward the most likely diagnosis.
- Clinical Reasoning
- Related: Differential Diagnosis, Diagnostic Error
The cognitive process clinicians use to gather and interpret data, weigh alternatives, and decide on diagnoses and management plans, integrating knowledge with patient-specific information.
- Diagnostic Error
- Related: Clinical Reasoning, Differential Diagnosis
A missed, delayed, or incorrect diagnosis that harms the patient or delays appropriate care, often resulting from cognitive biases, system failures, or incomplete information gathering.
- Red Flag
- Related: Triage, Emergency Severity Index
A clinical finding or history feature that raises concern for a serious underlying condition, prompting urgent evaluation or escalation of care rather than routine management.
- Sensitivity
- Related: Specificity, Predictive Value
The proportion of people who truly have a condition and are correctly identified by a test as positive; a highly sensitive test is useful for ruling out disease when negative.
- Specificity
- Related: Sensitivity, Predictive Value
The proportion of people who do not have a condition and are correctly identified by a test as negative; a highly specific test is useful for ruling in disease when positive.
- Predictive Value
- Related: Sensitivity, Specificity
The probability that a positive or negative test result correctly reflects the presence or absence of disease in a given population, depending strongly on disease prevalence.
- Number Needed to Treat
- Related: Absolute Risk Reduction, Confidence Interval
The number of patients who must receive an intervention for one additional patient to benefit, calculated as the reciprocal of the absolute risk reduction.
- Absolute Risk Reduction
- Related: Number Needed to Treat, Confidence Interval
The arithmetic difference in event rates between a control group and a treated group, expressed as a percentage or proportion, reflecting the actual clinical benefit of an intervention.
- Confidence Interval
- Related: Number Needed to Treat, Systematic Review
A range of values calculated from sample data that likely contains the true population parameter, usually expressed with a stated level of confidence such as 95%.
- Systematic Review
- Related: Meta-Analysis, Confidence Interval
A structured, comprehensive synthesis of all relevant studies addressing a focused question, using explicit methods to search, appraise, and combine evidence to reduce bias.
- Meta-Analysis
- Related: Systematic Review, Heterogeneity
A statistical technique that combines results from multiple independent studies to produce a pooled estimate of effect, increasing precision and power when studies are sufficiently similar.
- Heterogeneity
- Related: Meta-Analysis, Systematic Review
Variation in study results or populations beyond what would be expected by chance, which may make pooling data inappropriate and requires exploration of sources of difference.
- Informed Consent
- Related: Decision-Making Capacity, Advance Directive
A patient's voluntary agreement to a treatment or procedure after receiving and understanding information about its purpose, risks, benefits, and alternatives, and having the capacity to decide.
- Decision-Making Capacity
- Related: Informed Consent, Advance Directive
A patient's ability to understand relevant information, appreciate the consequences of choices, reason about options, and communicate a consistent decision regarding their care.
- Advance Directive
- Related: Informed Consent, Decision-Making Capacity
A legal document in which a person states their preferences for future medical care or appoints someone to decide on their behalf if they lose decision-making capacity.
- Confidentiality
- Related: HIPAA Privacy Rule, Mandatory Reporting
The ethical and legal obligation to protect a patient's private health information from unauthorized disclosure, with limited exceptions such as imminent harm or legally required reporting.
- Mandatory Reporting
- Related: Confidentiality, HIPAA Privacy Rule
A legal requirement for clinicians to report certain conditions or events, such as suspected child abuse, communicable diseases, or gunshot wounds, to designated authorities.
- Scope of Practice
- Related: Delegation, Standard of Care
The range of roles, activities, and responsibilities that a healthcare professional is legally and ethically permitted to perform based on licensure, training, and regulatory standards.
- Standard of Care
- Related: Scope of Practice, Negligence
The degree of care and skill that a reasonably prudent clinician with similar training would provide under similar circumstances, used as a legal benchmark in malpractice claims.
- Negligence
- Related: Standard of Care, Scope of Practice
Failure to exercise the standard of care that a reasonably prudent professional would use, resulting in harm; proving it requires duty, breach, causation, and damages.
- Pharmacokinetics
- Related: Pharmacodynamics, Therapeutic Index
The study of how the body affects a drug over time, encompassing absorption, distribution, metabolism, and excretion, which together determine drug concentration at sites of action.
- Pharmacodynamics
- Related: Pharmacokinetics, Therapeutic Index
The study of how a drug affects the body, including receptor interactions, dose-response relationships, and mechanisms of therapeutic and adverse effects.
- Therapeutic Index
- Related: Pharmacokinetics, Pharmacodynamics
A ratio comparing the dose that produces toxicity to the dose that produces a therapeutic effect; a narrow index means small dose changes can cause harm.
- Adverse Drug Reaction
- Related: Drug Interaction, Polypharmacy
An unintended, harmful response to a medication occurring at doses normally used for treatment, which may require dose adjustment, discontinuation, or reporting to safety systems.
- Drug Interaction
- Related: Adverse Drug Reaction, Polypharmacy
A change in a drug's effect caused by another drug, food, or substance, which can increase toxicity or reduce efficacy and often requires monitoring or dose adjustment.
- Polypharmacy
- Related: Drug Interaction, Adverse Drug Reaction
The concurrent use of multiple medications by a patient, which raises the risk of interactions, adverse effects, and medication errors, especially in older adults.
- Triage
- Related: Emergency Severity Index, Red Flag
A process of rapidly sorting patients by urgency of need so that limited resources are directed first to those with life-threatening or time-sensitive conditions.
- Emergency Severity Index
- Related: Triage, Red Flag
A five-level triage scale used in emergency departments that assigns acuity based on illness severity and expected resource needs, guiding patient prioritization and flow.
- Handoff Communication
- Related: SBAR, Closed-Loop Communication
The transfer of patient information and responsibility between clinicians or settings, ideally using a structured format to ensure accuracy and prevent omissions that could harm patients.
- SBAR
- Related: Handoff Communication, Closed-Loop Communication
A structured communication tool standing for Situation, Background, Assessment, and Recommendation, used to convey patient information clearly and efficiently during handoffs or escalations.
- Closed-Loop Communication
- Related: SBAR, Handoff Communication
A communication technique in which the receiver repeats back the message to confirm understanding, reducing errors in high-stakes settings such as emergency care and medication orders.
- Delegation
- Related: Scope of Practice, Handoff Communication
The assignment of a task to another team member while retaining accountability for the outcome, requiring that the task be within the delegate's scope and competence.
- Health Literacy
