The LForms Widget

An open source Javascript widget that creates data input forms based on LOINC’s rich content model.

LForms is a completely free widget toolkit that leverages LOINC's rich content model for panels, forms, and survey instruments. Developed by NLM's Lister Hill Center for Biomedical Communications in collaboration with the Regenstrief Institute,  LForms can read any of the 1,700+ panels defined in LOINC and render a powerful data entry form. It works across all of the domains (laboratory panels, survey instruments, etc) included in LOINC.

LForms power comes through its support of detailed form attributes, including: data type, cardinality, default value, units of measure (if numeric), answer lists (if multiple choice), relationship (in a hierarchy) to other questions, validation checks, skip logic and help messages.

iPad LForms - 300

 

We've also built tight integration into RELMA and search.loinc.org.

 

Thinkpad RELMA - 600

 

You can now get quickly from a LOINC panel term to an example data entry form that's hosted here on the loinc.org website from all of these places:

  1. Panels, Forms & Surveys screen
  2. Search result grids and details pages in RELMA
  3. Search result grids and details pages in search.loinc.org

Out of the box, Forms does not include a mechanism to actually store data in a system like and EHR or PHR, but it would not be very difficult for an experienced developer. Likewise, authentication and user control are pieces you would need to add your own custom solution for.
