Health research overview

Health and medical research improves the health and wellbeing of people.

It is concerned with discoveries about:

  • how our bodies and minds function and how they respond to disease
  • the development of new drugs, procedures and therapies
  • influencing behaviour to improve health
  • making our health services more effective and efficient.

Health research encompasses many disciplines and is undertaken in diverse settings, including hospitals, universities and the community.

Qualitative and quantitative research

When planning or critically appraising research papers, you need to consider how well the methods used to collect and analyse data support the researcher's hypothesis or findings and how well it answers the research question. These methods are broadly categorised as Quantitative or Qualitative, or Mixed Methods (using both approaches). 

The table below summarises the differences between the two approaches.  


Experimental and statistical 

Allows you to test a hypothesis 

Naturalistic and interpretive; ethnographic and phenomenological 

Allows you to formulate a hypothesis


Measure, test, predict and describe using statistics

(how much? how often?)

Rich descriptions of behaviours and realities 

(explore what? why?) 


Requires a large sample size 

Experiments, surveys/questionnaires/large datasets/structured interviews and observations (recorded as numbers). 

Requires the same question criteria for each participant

Generally a small sample size  

Field research, case studies, open-ended interviews and observations. 

Allows room for flexibility and follow-up


Generally expressed in numbers 

Numerical or quantifiable 

Generally expressed in words

Interviews, transcripts, notes, journal entries

Data analysis techniques Statistical analysisTextual analysis
FindingsCan be used to establish generalisable facts about a topic Primarily exploratory research to explain or understand a topic

Translating research into practice (TRIP)

The creation of knowledge does not, of itself, lead to widespread implementation and positive impacts on health. The knowledge must be translated into changes in practice and policy for the benefits and impacts to flow.

Source: Research translation (NHMRC).

Translation science, also known as implementation science, is testing implementation interventions to improve uptake and use of evidence to improve patient outcomes and population health.

Research ethics and governance

It is a requirement that all health research be conducted in an ethical manner.  

Ethics, integrity and compliance Explains the processes UQ researchers must follow when conducting their research.

Reviews and other types of research

There are many different types or methods of research used in health, ranging from a traditional literature review to a meta-analysis.

When reporting research, you can adopt a standard approach for undertaking, writing and publishing your research. For example, the EQUATOR Network provides reporting guidelines for different study types.

The word review may mean different things. Literature reviews range from narrative or traditional literature reviews to systematic reviews, scoping reviews or systematic quantitative reviews.

Literature reviews guideExplains different types of literature reviews and the difference between literature reviews and systematic reviews.

Systematic reviews guideProvides an overview of systematic reviews and resources to support producing one.

Systems, tools and techniques to support health research

The research process has many facets. These include finding, using and managing information and data, using research software tools, disseminating your research outputs, as well as complying with institutional and government requirements.

We provide guides for researchers on key tools and systems and how to use them:

  • UQ eSpace is UQ's institutional repository to keep your research output and research data profile up to date.
  • UQ Research Data Manager stores and manages research data for research projects for UQ HDR students and staff.
  • Digital Research Notebooks can be requested and uses a notebook to store, organise, curate and share all your project's research data and research notes for UQ HDR students and staff

Research techniquesHow to find, analyse and visualise research information and data, including data visualisation, text mining and text analysis and using NVivo in systematic reviews.

How to findTechniques and resources to find specific information formats, including research data, statistics, grey literature and government information.

Finding data and statistics

Before you start searching for research data, you must define the data you are looking for. This will help focus your search and the sources you use. It means not only considering your research discipline, but also the nature of data you require. For example:

  • the variables required
  • geographical location
  • timeframes
  • frequency of data collection
  • the data analysis tools you will use.

Sources of data include government websites, data catalogues, data directories and institutional repositories. Before you start searching determine whether you need data or statistics. It can also help you decide if you have found suitable data for your research.

Data versus statistics

Statistics are the results of data analysis - its interpretation and presentation, whereas data is the individual items of factual information that have been recorded.

Data versus statistics has further information.
