How do CINAHL, PubMed compare side by side?
The table below compares CINAHL, PubMed across 7 procurement-relevant dimensions, from producer and access through best used for.
Side-by-side comparison
| Dimension | CINAHL | PubMed |
|---|---|---|
| Producer and access | EBSCO; subscription only, usually via an institutional library | US National Library of Medicine; free to anyone |
| Disciplinary scope | Nursing, biomedicine, alternative and complementary medicine, consumer health, and 17 allied health disciplines | Biomedicine and life sciences broadly |
| Subject headings | CINAHL Subject Headings — structured on MeSH, with additional domain-specific terms | MeSH |
| Non-journal material | Books and book chapters, nursing dissertations, selected conference proceedings, standards of practice, audiovisuals | Journal literature; does not index dissertations or standards of practice |
| Tiered products | Several tiers with different coverage — from CINAHL with Full Text at 315 active full-text journals up to CINAHL Ultimate at 1,892 | One database; no tiers |
| Open access | Curated and indexed OA content, including 1,570 active global OA journals | Links to free full text where available; PubMed Central is a separate archive |
| Best used for | Nursing and allied health questions, and grey literature such as dissertations and practice standards | Almost any biomedical question, and always as a free baseline search |
Common questions
Common questions about CINAHL vs PubMed
Is CINAHL just a nursing version of PubMed?
+
Not quite. The disciplinary focus is the obvious difference, but the more consequential one is material type: CINAHL indexes dissertations, standards of practice, book chapters and conference proceedings, none of which PubMed covers. That makes it a grey-literature source as much as a subject database.
Can I reuse my PubMed search in CINAHL?
+
Not unchanged. CINAHL Subject Headings are structured on MeSH but add domain-specific terms, so headings must be mapped rather than copied, and the EBSCO syntax differs from PubMed’s. A pasted MeSH strategy will run and quietly under-retrieve.
Does "we searched CINAHL" mean the same thing everywhere?
+
No, and this is worth stating in a methods section. CINAHL is sold in tiers whose full-text coverage ranges from 315 active journals to 1,892. Two reviews can both report searching CINAHL and have searched materially different corpora, so name the specific product.
Do I still need PubMed if I have CINAHL?
+
Yes. PubMed is free, broader in biomedicine, and the baseline expectation for any health-related review. CINAHL adds depth and material types on top; it does not replace a general biomedical search.
Is CINAHL useful outside nursing?
+
Yes, within its scope — it covers 17 allied health disciplines plus alternative and complementary medicine and consumer health, so physiotherapy, occupational therapy, speech and language, and similar fields are well served.
Is PubMed the same as MEDLINE?
+
No. MEDLINE is the MeSH-indexed subset; PubMed is the interface and includes MEDLINE plus additional records such as ahead-of-print citations. Protocols that specify "MEDLINE" usually mean the indexed subset.
