MCCQE Part I key terms

A structured account of the onset, course, character, severity, timing, and modifying factors of a patient's current problem, plus associated symptoms and the patient's own concerns and expectations.

A systematic screen of symptoms by organ system, asked after the main history, to uncover problems the patient has not volunteered and to guide the physical examination.

A record of prior illnesses, surgeries, hospitalizations, injuries, immunizations, and chronic conditions that shape the patient's current risk and management options.

The formal process of obtaining and comparing a complete list of a patient's medications, including over-the-counter products and supplements, across care transitions to prevent errors and interactions.

A prioritized list of plausible explanations for a patient's presentation, ranked by likelihood and by the harm of missing each condition, used to direct further testing.

A feature in the history or examination that signals possible serious or urgent disease and prompts expedited investigation or referral rather than routine management.

The estimated likelihood that a patient has a condition before a test is performed, based on history, examination, and local prevalence; it determines how a test result should be interpreted.

The proportion of people who truly have a condition and are correctly identified by a test; a highly sensitive test is useful for ruling a condition out when negative.

The proportion of people without a condition who are correctly identified as negative by a test; a highly specific test is useful for ruling a condition in when positive.

A ratio expressing how much a given test result changes the odds of disease; values far from one substantially shift post-test probability and support clinical decisions.

The number of patients who must receive an intervention for one additional person to benefit, calculated as the reciprocal of the absolute risk reduction.

The arithmetic difference in event rates between control and treatment groups, reflecting the actual size of benefit a patient may expect from an intervention.

The integration of the best available research evidence with clinical expertise and the patient's values and circumstances when making decisions about care.

Systematically developed recommendations intended to help clinicians and patients make decisions about appropriate care for specific clinical circumstances, ideally adapted to local context.

A campaign of recommendations identifying tests and treatments that are commonly overused and offer little benefit, encouraging clinicians to discuss necessity and avoid low-value care.

The responsible use of limited health care resources, balancing benefit to the individual patient against the needs of the wider population, without withholding effective care.

The presence of one or more additional conditions alongside an index disease, which can complicate treatment, affect prognosis, and change the risk-benefit balance of interventions.

The concurrent use of multiple medications, often five or more, which raises the risk of interactions, adverse effects, and non-adherence, particularly in older adults.

The planned, supervised withdrawal of medications that are no longer beneficial or are causing harm, undertaken with the patient to reduce pill burden and adverse effects.

Any injury or harm resulting from a medication, whether from an error, an interaction, an allergic reaction, or an expected side effect at a therapeutic dose.

A patient's voluntary agreement to a treatment or procedure after receiving and understanding information about its purpose, benefits, risks, and reasonable alternatives.

A patient's ability to understand relevant information and appreciate the consequences of a specific decision at a specific time; it is decision-specific rather than global.

A person legally authorized to make health care decisions on behalf of a patient who lacks capacity, guided by the patient's previously expressed wishes or best interests.

A process of discussing and recording a patient's values, goals, and preferences for future care, used to guide decisions if the patient later loses capacity.

The agreed aims of a patient's treatment, such as cure, prolonging life, comfort, or function, which direct which interventions are appropriate as illness progresses.

A collaborative conversation in which clinician and patient exchange evidence and values to reach a mutually agreed choice among reasonable options.

A tool that presents the options, benefits, and harms of a health decision in plain language, helping patients clarify values and participate meaningfully in shared decision-making.

A patient's ability to obtain, understand, and use health information to make decisions; low health literacy requires plain language, teach-back, and extra support.

A communication technique in which the clinician asks the patient to restate information in their own words, confirming understanding and revealing gaps to be addressed.

Professional language support used when clinician and patient do not share a fluent language, avoiding errors and inequity that arise from using untrained interpreters such as family members.

Advice given to a patient about what to expect, which symptoms should prompt return, and how to access care urgently if the condition worsens or fails to improve.

A team communication pattern in which a message is sent, repeated back by the receiver, and confirmed by the sender, reducing error in high-stakes handovers and orders.

A structured communication format (Situation, Background, Assessment, Recommendation) used to convey concise, prioritized information between clinicians, especially when escalating concerns.

The transfer of responsibility and essential clinical information between care providers, which should be structured, complete, and allow the receiver to ask questions.

Working with professionals from different disciplines, sharing roles and information, to plan and deliver coordinated care that no single provider could achieve alone.

The activities, responsibilities, and limits of a health professional's role as defined by training, legislation, and employer policy, which must be respected when delegating or sharing care.

The transfer of a specific task to another team member who is competent to perform it, with the delegator retaining accountability for appropriate supervision and follow-up.

A structured approach to disagreement within a team that separates people from problems, explores interests, and seeks a mutually acceptable solution, escalating formally if needed.

An organizational approach that distinguishes human error from reckless behavior, encouraging reporting of mistakes while holding people accountable for unsafe choices.

An event or near miss that could have caused or did cause harm to a patient; it should be disclosed, reported, and analyzed to prevent recurrence.

An open, timely conversation with a patient or family after an adverse event, explaining what happened, expressing regret, and outlining what will be done next.

A systematic, data-driven method for continuously improving care processes and outcomes, often using plan-do-study-act cycles and measured indicators.

A quality improvement approach that compares a clinician's or team's performance against a standard and provides targeted feedback to close the identified gap.

The interval a patient waits for an appointment, diagnostic test, or procedure; it is a key access measure that clinicians can influence through prioritization and appropriate referral.

The process of sorting patients by urgency of need so that limited time and resources are directed first to those who will benefit most or deteriorate soonest.

Decisions about distributing limited health care goods such as beds, organs, or staff, guided by transparent criteria of need, benefit, and fairness.

A state of reduced physiological reserve and increased vulnerability to stressors, which predicts poorer outcomes and should prompt adjusted treatment goals and supports.
