A

Adverse event

Any unwanted medical occurrence or other safety issue that happens during a research study. Adverse events should be recorded, reported, and managed according to the study protocol.

Always-on preparedness

The continuous development of research skills, systems, and experience through routine health research so that teams are ready to respond rapidly when a new outbreak or health emergency occurs.

Analysis

The process of examining collected data to answer the research question and draw conclusions. Analysis should follow the plan described in the study protocol.

Analysis plan

A description of how the collected data will be analysed to answer the research question. It should be planned before the study begins.

Audit

An assessment of whether current practice meets established standards. Unlike research, an audit aims to improve local practice rather than generate new knowledge.

An ethical principle requiring researchers to maximise potential benefits while minimising harm to participants.

Bias

A systematic error that may influence study findings and reduce their accuracy or reliability.

Biosafety

Measures used to protect people, the environment, and laboratory staff when handling potentially infectious materials.

Clinical trial

A research study that prospectively assigns participants to one or more health-related interventions to evaluate their effects on health outcomes.

Community engagement

Working with communities before, during, and after research to build trust, improve study relevance, and support the use of findings.

Confidentiality

Protecting participants’ personal information so it is only accessed by authorised individuals.

The systematic gathering of information needed to answer the research question.

Data management

The organisation, storage, protection, and maintenance of study data throughout the research process.

Data sharing

Making research data available to other researchers through appropriate governance, ethical safeguards, and data-sharing processes.

Declaration of Helsinki

An internationally recognised statement of ethical principles for research involving human participants.

Descriptive research

Research that describes a disease, population, or health problem without investigating cause-and-effect relationships.

Dissemination

Sharing research findings with people who can use them, including healthcare workers, policymakers, communities, and other researchers.

E

Ethical approval

Independent review and approval of a research study to ensure that it meets ethical standards and protects participants.

Ethics committee

An independent group that reviews research studies to protect the rights, safety, and wellbeing of participants.

Evidence

Information generated through systematic research that helps answer questions and inform healthcare decisions.

Evidence gap

An important question or uncertainty that existing evidence has not yet answered.

Explanatory research

Research that explores relationships between factors to help explain why something happens.

Exposure

Contact with a factor that may influence the risk of disease or another health outcome.

Feasibility

Whether a study can realistically be carried out using the available staff, resources, equipment, funding, and time.

G

Generalisable knowledge

Knowledge that can be applied beyond the setting where the research was conducted.

Genomics

The study of the genetic material of organisms, including pathogens, to understand how they evolve and spread.

H

Health research

The systematic attempt to generate new, transferable, or generalisable knowledge using scientifically sound methods.

Hypothesis

A specific statement or prediction that a study is designed to investigate.

I

Implementation

Putting the approved study protocol or research findings into practice.

Implementation pathway

The process of translating research findings into healthcare practice, policy, or public health action.

Intervention

A treatment, diagnostic test, preventive measure, or other action being evaluated in research.

J

Justice

An ethical principle that requires fairness in selecting participants and distributing the benefits and burdens of research.

Back to top ↑

K

Knowledge, attitudes and practices study

A type of social science research used to understand what people know, believe, and do about a health issue.

M

Metadata

Information that describes research data, such as when and where a sample was collected or how the data were generated.

Mixed-methods research

Research that combines quantitative and qualitative approaches to answer a research question.

N

Non-maleficence

An ethical principle requiring researchers to avoid causing unnecessary harm.

O

Observational study

A study in which researchers observe participants without assigning interventions.

Outbreak

The occurrence of more cases of a disease than expected in a particular place or population.

Outcome

The result or effect measured during a research study.

P

Participant

A person who takes part in a research study.

Pathogen

A microorganism, such as a virus, bacterium, fungus, or parasite, that causes disease.

Patient and Public Involvement and Engagement

The active involvement of patients, communities, and members of the public in shaping research rather than simply participating in it.

Phylogenetics

The study of evolutionary relationships between organisms using genetic information.

Predictive research

Research that estimates future outcomes or identifies factors that may predict an outcome.

Primary objective

The main question that a study is designed to answer.

Principal Investigator

The person with overall responsibility for the scientific, ethical, and operational conduct of a research study.

Protocol

The detailed plan for a study. It explains what the study will do, why it is being done, who will be involved, how it will be carried out, and how the research question will be answered.

Protocol deviation

A departure from the approved study protocol.

Q

Qualitative research

Research that explores people’s experiences, views, behaviours, and perceptions using methods such as interviews or focus groups.

Quantitative research

Research that collects numerical data to measure, compare, or investigate relationships.

A method of allocating participants to different study groups by chance to reduce bias.

Research question

The specific question that the study is designed to answer.

Routine clinical care

Healthcare provided as part of normal patient management without the intention of generating new, generalisable knowledge.

Scientific integrity

Conducting research honestly, accurately, transparently, and according to accepted scientific standards.

Secondary objective

An additional question that supports the main aim of the study.

Service evaluation

An assessment of how well a healthcare service is working, undertaken to improve local services rather than generate generalisable knowledge.
