Corrections policy

When an error is identified, the editorial desk checks the underlying source and the scope of the error. A correction to a fact is distinguished from a new development that changes an otherwise accurate earlier statement.

A material correction should state what changed, when it changed and which article was affected. The corrected text and relevant source should agree. An update to a clinic's hours should not silently change unrelated treatment claims or an article's original publication date.

Useful correction information includes the article title or URL, the disputed statement and a supporting document or direct source. Patient records and other sensitive personal information are not needed to flag a public factual error.
