Show Me the Evidence! Why Evidence-Based Medicine Matters

Nicoleta Popa, Physiotherapist at Teladoc Health UK, shares useful insight into what is meant by evidence-based practice.

What does “evidence” mean?

Evidence is the means of proving an unknown or disputed fact, support for a belief, an indication, information in a lawsuit, testimony, or a witness. In the context of medical practice, evidence may take the form of research—a systematic investigation aimed at increasing the sum of knowledge.

Evidence-based medicine essentially involves combining the best available research with a clinician’s experience and what matters most to the patient. “Patient values” refer to each person’s unique preferences, concerns, and aspirations regarding their care. When healthcare professionals and patients collaborate in this manner, it typically results in better outcomes and an enhanced quality of life. It’s an approach that we have used for years at Teladoc Health UK.

Why is this important for employers and organisations?

Providing employees with access to virtual healthcare grounded in evidence-based medicine ensures they receive high-quality, effective care while improving convenience and overall wellbeing.

What counts as evidence in evidence-based practice?

There are four main types of evidence used when delivering care:

• Research

• Clinical experience

• Patient experience

• Information from the local setting

Using these different types of evidence involves combining two ways of thinking — the scientific approach (based on data and studies) and the intuitive approach (based on personal experience and insight). This mix ensures that what’s being done is effective and done in the best possible way.

Evidence-based practice isn’t something that remains constant over time. It’s constantly evolving as new research emerges, replacing older tests and treatments with ones that are more effective, accurate, and safer.

Evidence-Based Practice Guidelines

Evidence-based practice guidelines (PGs) comprise the concrete and specific steps required to implement various interventions (medical or psychosocial) that credible research indicates are first-choice treatments for specific problems or areas of concern. PGs are also referred to as practice protocols, treatment algorithms, or clinical pathways.
