MedlinePlus Connect and Electronic Health Records
Today the National Library of Medicine (NLM) announces MedlinePlus Connect (http://medlineplus.gov/connect), a free service that allows electronic health records (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 medications. NLM mapped MedlinePlus health topics to two standard diagnostic coding systems used in EHRs: 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 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. The API for using this service conforms to the HL7 Context-Aware Knowledge Retrieval (Infobutton) Knowledge Request URL-Based Implementation specification.
MedlinePlus responds to problem code requests in either English or Spanish. Currently, it supports requests for drug information in English only. NLM is working on adding laboratory test responses to MedlinePlus Connect. We will also support an XML-based Web service at a future date.
