What is clinical research methodology?
A clinical study involves research using human volunteers (also called participants) that is intended to add to medical knowledge. There are two main types of clinical studies: clinical trials (also called interventional studies) and observational studies.
How will you design clinical study methodology?
Overview of methodologies used within a study design
- Simple randomization. In simple randomization, the subjects are randomly allocated to experiment/intervention groups based on a constant probability.
- Block randomization.
- Stratified randomization.
What are examples of clinical research?
Examples of other kinds of clinical research
- A long-term study that involves psychological tests or brain scans.
- A genetic study that involves blood tests but no changes in medication.
- A study of family history that involves talking to family members to learn about people’s medical needs and history.
What is methodology in RCT?
RCTs belong to a class of methodologies called experimental research or interventional study designs, which manipulate an intervention, rather than only observing and measuring.

- Pilot studies and feasibility studies.
- Prevention trials.
- Screening trials.
- Treatment trials.
- Multi-arm multi-stage (MAMS) trials.
- Cohort studies.
- Case control studies.
- Cross sectional studies.
What are the 4 phases of clinical trials?
Summary
| Phase | Primary goal |
|---|---|
| Phase I | Dose-ranging on healthy volunteers for safety |
| Phase II | Testing of drug on participants to assess efficacy and side effects |
| Phase III | Testing of drug on participants to assess efficacy, effectiveness and safety |
| Phase IV | Post marketing surveillance in public |
What are the 4 types of research methods?
Data may be grouped into four main types based on methods for collection: observational, experimental, simulation, and derived.
What are the 4 types of study design?
There are four main types of Quantitative research: Descriptive, Correlational, Causal-Comparative/Quasi-Experimental, and Experimental Research. attempts to establish cause- effect relationships among the variables. These types of design are very similar to true experiments, but with some key differences.
Why RCT is the gold standard?
Randomized controlled trials According to the hierarchy of evidence for the evaluation of health care outcomes ( 9 )—the best way for seeking the truth are RCTs. They are considered as the gold standard because they deliver the highest level of evidence, due to their potential to limit all sorts of bias.
What are the two types of randomized trials?
These types of randomized controlled trials include parallel, crossover, and factorial designs. Parallel design. —Most randomized controlled trials have parallel designs in which each group of participants is exposed to only one of the study interventions. Crossover design.

Phase 5 Clinical Trials are commonly referred to as “post-marketing clinical trials”.
What are examples of research methodology?
Depending on the purpose, your research method may take different forms. Some of the examples of research methods are: experimental, expository, action, pure, and applied research. Also, based on the source of materials for the research and study, you may have primary research and secondary research.
What kind of research do clinical researchers do?
Clinical research helps generate scientific data Clinical researchers work in a medical center or clinic, with a team who gathers data and monitors side effects and patient wellbeing in the laboratory. The researchers investigate medication efficacy, potency, dosing, side effects, as well as drug impact on study volunteers.
What does clinical research mean?
Clinical research. Clinical research is a branch of healthcare science that determines the safety and effectiveness (efficacy) of medications, devices, diagnostic products and treatment regimens intended for human use. These may be used for prevention, treatment, diagnosis or for relieving symptoms of a disease.
What are clinical methods?
The clinical method is the scientific method applied to the care of a patient. Decision making and therapeutics are the last part of the clinical method, going to the active contemplation to action, and from identification and knowledge to transformation until it is permitted by science and individuality of each patient.
