Research findings and routine care: why the distinction matters
A research report can answer an important scientific question without establishing that a treatment is suitable for routine use. Reading the study's purpose, stage and limitations helps put a headline in context.
Identify the stage of research
Laboratory work and studies in humans answer different questions. In drug development, clinical trials gather information about safety, effectiveness and dose in people. A promising laboratory result does not, by itself, answer those clinical questions.
A study and a marketed treatment have different status
For investigational cell therapy drugs, authorization to conduct a clinical trial differs from authorization for general sale. A paper, laboratory credential or licensed preparation device is not a substitute for checking the status of the particular product and use.
Research participation involves an ongoing discussion
Health Canada describes research consent as voluntary, informed and ongoing. Information should be understandable, with time for questions. Participation is not a promise of personal benefit, and consent is more than signing a form once.
Read a summary with four questions in mind
These questions help separate what a study reports from what a reader might assume. A useful explanation includes uncertainties as well as findings.
- What material or treatment was studied, and in whom?
- Which outcome was measured?
- What risks and limitations were reported?
- Does the description distinguish research from an available clinical service?
