Which statement correctly captures a fundamental principle of evidence-based practice regarding sufficiency of evidence?

• A. Evidence alone is sufficient to guide decisions.
• B. A hierarchy of evidence is optional.
• C. Evidence alone is never sufficient.
• D. Baseline data alone is enough.

Answer: (C)

Evidence alone is never sufficient to guide decisions in evidence-based practice. Strong research helps, but its findings must be interpreted and applied in the context of the individual patient, the clinical setting, and available resources. Clinical expertise is needed to judge how applicable the study results are, what the risks and benefits mean for a specific patient, and how feasible an option is in real life. Patient values and preferences also shape what outcomes matter and what trade-offs are acceptable, so decisions cannot rest on data alone. This combination—best available evidence, clinical judgment, and patient context—drives sound practice. If we kept only the data, we’d risk misapplying results to someone who differs in important ways. Relying on a hierarchy of evidence is a helpful tool for assessing quality and relevance, not something to skip. Baseline data describe where we start but don’t tell us which intervention to choose or what outcomes will occur, so they aren’t sufficient by themselves.
