Useful refers to knowledge, tools, or actions that produce meaningful improvement in real contexts — especially in patient care, clinical reasoning, or surgical decision-making.

In Neurosurgery Wiki, we use “useful” not in the abstract sense of “interesting” or “publishable,” but in the concrete sense of:

*“Would this help someone operate better, decide more wisely, or avoid a mistake?”*

• It changes how you see a case or a decision
• It can be applied directly in clinical practice
• It saves time, prevents harm, or sharpens judgment
• It teaches something that stays with you — not just fills a page

• Data that hides behind jargon or statistics
• Content designed to impress rather than inform
• Redundant, vague, or prestige-driven publications
• Anything that adds noise, not clarity

“Useful” is the highest compliment a piece of clinical knowledge can earn.
