Question: What's the difference between MedlinePlus and MedlinePlus Connect?
MedlinePlus Connect is a free service that allows electronic health record (EHR) systems to easily link users to MedlinePlus, an authoritative up-to-date health information resource for patients, families and health care providers. MedlinePlus Connect is not a replacement to MedlinePlus. It helps users of EHRs find health information from MedlinePlus.
MedlinePlus Connect accepts requests for information on diagnoses (problem codes), lab tests and medications.
To use MedlinePlus Connect to link out from an EHR, you need to work with the technical representative or staff member who can add links to your EHR system as described in the technical documentation.
