DynaMedex is a clinical decision support product from EBSCO Information Services and Merative that combines DynaMed (disease and condition content) with Micromedex (medication information). It was announced under that name on October 11, 2022, replacing the earlier name “DynaMed and Micromedex with Watson”. If you are a librarian, researcher or administrator trying to place it among other resources, the key point is that it is a point-of-care reference, not a bibliographic database like PubMed.
What is DynaMedex?
EBSCO’s press release of October 11, 2022 describes DynaMedex as the renamed integrated solution formerly called DynaMed and Micromedex with Watson, and as EBSCO’s flagship Clinical Decisions product. The partnership between EBSCO and Merative that preceded the rename began in March 2020, according to the same release. EBSCO’s executive vice president of Clinical Decisions, Betsy Jones, is quoted there saying DynaMedex “will continue to serve as a one-stop-shop for clinicians at the point of care.”
What is the difference between DynaMed and DynaMedex?
DynaMed is one half of DynaMedex; DynaMedex is the combined product. The 2022 release separates the two as follows:
| Name | What the publisher says it is | Main content |
|---|---|---|
| DynaMed | Peer-reviewed clinical content with recommendations backed by recent evidence (EBSCO) | Disease topics, health conditions and abnormal findings, including focused topics on evaluation, differential diagnosis and management |
| Micromedex | An evidence-based online reference database for medication information (Merative) | Medication therapy management, toxicology, alternative medicine and patient education |
| DynaMedex | The integrated solution combining both, renamed in October 2022 | Disease content from DynaMed plus drug content from Micromedex |
So the practical answer to “DynaMed vs DynaMedex” is a scope difference: DynaMed on its own is disease and condition content, while DynaMedex adds the Micromedex medication reference alongside it. Older library guides and citations may still use the earlier names.
What does DynaMed do?
According to the 2022 release, DynaMed provides peer-reviewed clinical content covering disease topics, conditions and abnormal findings. The release also names two tools associated with it: DynaMed Decisions, which is intended to support patient-clinician interactions and shared decision-making, and Isabel, a diagnostic decision support tool available within DynaMed. Peter Oettgen, MD, is named in the release as DynaMed’s Editor in Chief.
Who runs it and what does it cover?
Two organisations are involved: EBSCO Information Services (DynaMed and the Clinical Decisions product line) and Merative (Micromedex). The 2022 release states that Micromedex is used by more than 3,300 hospitals and health systems worldwide; that is the publisher’s figure as of the release date and is not a current count. EBSCO’s own “DynaMedex Difference” page describes coverage of disease and condition evidence, differential diagnosis algorithms, shared decision-making tools and drug evidence, aimed at clinicians at the point of care.
Is DynaMedex good?
This page does not rank or rate products. What can be said from the publisher’s own statements is limited to: DynaMed was named 2022 Best in KLAS for Clinical Decision Support, its second consecutive year, according to the 2022 release (a vendor-reported award). Whether any clinical reference is suitable for a given use depends on the questions it must answer, the populations and regions it needs to cover, how its editorial and update process fits your institution’s requirements, and how it connects to your workflows. Those are criteria for your own evaluation against the publisher’s current documentation and your institution’s licence, not findings from this page.
What is the best search engine for medicine?
There is no single best one, because different tools answer different questions. Literature databases such as PubMed index published research; point-of-care references such as DynaMedex, UpToDate or Micromedex summarise evidence and drug information for clinical questions. Choose by task: finding primary studies, reading a synthesised topic overview, or checking medication information. For the literature side, see our guides to Europe PMC and PubMed Europe, PubMed Clinical Queries filters and what MEDLINE selection does and does not tell you.
How to use it
Search steps and interface terms are specific to each institution’s licence and the current product version, and are documented by the publisher and by your library’s own DynaMedex guide. Start from your library or hospital intranet link, which is where subscribers normally reach the product.
Strengths and limits
- Strength, per the publisher: disease and drug content in one product, aimed at the point of care.
- Strength, per the publisher: built-in decision aids (DynaMed Decisions, Isabel).
- Limit: it is a synthesised reference, not a database of primary studies. For a systematic review you still need bibliographic sources such as PubMed or Scopus.
- Limit: the figures quoted above come from a 2022 vendor release and may have changed.
Alternatives
These are alternatives in the sense of overlapping use, stated as each publisher describes them. This is not a ranking.
| Resource | Publisher | What it is, per the publisher |
|---|---|---|
| UpToDate (with Lexicomp) | Wolters Kluwer | A clinical decision support tool; Lexicomp is its companion drug information tool (Wolters Kluwer release, 2021) |
| Micromedex (standalone; see our Micromedex guide) | Merative | An evidence-based online reference database for medication information (EBSCO release, 2022) |
| PubMed | U.S. National Library of Medicine | A free bibliographic database of biomedical literature, covered in our PubMed and Europe PMC guide |
