The following was posted by the National Library of Medicine.

“Today the National Library of Medicine announces MedlinePlus Connect (http://medlineplus.gov/connect), a free service that allows electronic health record (EHR) systems to link users to MedlinePlus (http://medlineplus.gov), an authoritative up-to-date health information resource for patients, families and health care providers. MedlinePlus provides information about conditions and disorders, medications, and health and wellness.

MedlinePlus Connect accepts requests for information on diagnoses (problem) codes and medication codes already used in the EHRs. NLM has mapped MedlinePlus health topics to two standard diagnostic coding systems: ICD-9-CM and SNOMED CT CORE Problem List Subset. When an EHR submits a request to MedlinePlus Connect, the service returns the closest matching health topic(s) as a response.  MedlinePlus Connect also links EHR systems to drug information written especially for patients. For medication codes, MedlinePlus Connect accepts RXCUIs and NDCs. MedlinePlus responds to problem code requests in either English or Spanish. Currently, it supports requests for drug information in English only.

The API for this service conforms to the HL7 Context-Aware Knowledge Retrieval (Infobutton) Knowledge Request URL-Based Implementation specification.  NLM is working on adding laboratory test responses to MedlinePlus Connect. We will also support an XML-based Web service at a future date.

You can find more background and technical information at http://medlineplus.gov/connect. We also have an email list (http://www.nlm.nih.gov/medlineplus/connect/emaillist.html) for EHR developers and others interested in staying up-to-date on technical developments, or talking to other organizations that are using it.

To use MedlinePlus Connect, you need to work with the technical representative or staff member who can add links to your EHR system as described in the MedlinePlus Connect technical documentation. To send us questions or feedback, use the MedlinePlus Contact Us link at http://apps.nlm.nih.gov/medlineplus/contact/index.cfm.
