Evidence literacy · 4 min read

Read the claim. Then examine the evidence.

Understand source checks, independence, study quality, and what an unknown actually means.

The useful distinction

A checked source, independent research, and a locally useful result are three different things.

01

Begin with the exact claim

Identify the outcome, denominator, comparison, setting, and time period. 'Reduced administrative work' is not equivalent to a measured reduction in total staff hours. Keep the claim close to what the source actually establishes, including qualifications.

Questions to take into the conversation

  • Is this a measured outcome, a deployment announcement, or an estimate?
  • Is the comparison before-and-after, concurrent, randomized, or absent?
  • Were implementation costs and adverse results reported?
02

Source class is a starting point

Peer review does not remove conflicts of interest or guarantee generalizability. An independent publication may report a vendor's unverified statement. A regulatory record answers a defined regulatory question. Read the underlying material before drawing a broader conclusion.

Questions to take into the conversation

  • Who produced the underlying data?
  • What role did the vendor play in funding, analysis, and publication?
  • Does the population and product version match your intended use?
03

Read HealthIT's labels precisely

A source-checked claim passed our documentary verification process. Source independence is a separate attribute. Freshness is calculated at the displayed snapshot cutoff, not continuously. A product outside the evidence standard remains useful to research; the exclusion describes this corpus, not the product's quality.

Questions to take into the conversation

  • Open the claim's source and its verification state.
  • Check the source date and the snapshot cutoff.
  • Record the missing evidence that would change your decision.
