2011 08 15 - Clinical LOINC Tutorial - Collections - Panels Forms and Assessm...
This document summarizes a presentation on using LOINC (Logical Observation Identifiers Names and Codes) to standardize clinical assessments and patient-reported outcomes. It describes how LOINC provides a model for organizing assessments into hierarchical panels and items with specific attributes. A growing number of standardized assessments are available in LOINC, including government forms, clinical screening tools, and patient-reported outcomes. Lessons learned include the need to minimize variation between similar assessments and start from a uniform data model to avoid discrepancies. IP issues also present challenges for widespread adoption.
2011 08 15 - Clinical LOINC Tutorial - Documents
This document summarizes a presentation on the clinical document ontology (CDO) developed by LOINC. It describes the origins and development of having a standardized vocabulary for clinical document names, including empirical analysis of local document names. The presentation reviews the multi-axial model used by LOINC for document names, provides examples, and discusses ongoing evaluation and expansion efforts through collaboration. Future directions include further harmonization of CDO terms and analyzing document content.
2011 06 06 - LOINC Workshop and Tutorial
The document provides an overview of the Regenstrief LOINC Mapping Assistant (RELMA) tool. It discusses RELMA's features for installing the tool, setting preferences, loading local observation files, searching for and mapping local terms to LOINC codes, and proposing new LOINC terms. The goal is to help laboratories map their local test names and codes to standardized LOINC codes to improve data interoperability, comparability and quality.
2011 06 06 - LOINC Introduction

2011 01 27 - Clinical LOINC Tutorial - Panels Forms Patient Assessments
This document discusses LOINC's model for standardizing patient assessments and forms. It provides an overview of LOINC's current efforts to represent common health assessments, including various government forms and clinical screening tools. The presentation notes that while these assessments address similar concepts, there is significant variation in how the items are structured between different forms. It recommends starting with LOINC's standardized data model to help address inconsistencies and avoid unnecessary variation. Lessons learned include the high costs of losing comparability and that intellectual property issues pose large challenges for standardization.
2011 01 27 - Clinical LOINC Tutorial - Documents
The document discusses the origins and ongoing development of a document ontology within LOINC and HL7. It describes how the Clinical Document Ontology (CDO) provides consistent semantics for clinical document names to enable interoperability. The CDO uses a multi-axial model with domains like subject matter, role, setting, type of service, and kind of document. Iterative evaluations have helped expand and refine the CDO. Future work includes further harmonization and expanding the model to new document types.
2010 12 06 - LOINC Workshop

- The pig picture was on an old t-shirt that was found stuffed under something when we moved offices. I cut the pig out and put it in an 8 x 10 frame that we had. I took a picture of it with my cell phone and emailed it to myself. Then I inserted the picture into a blank powerpoint and VOILA - The French Pig. (Sandy Poremba) Do we know who the original artist was? (Stan) I think it was Jill Warvel - a programmer from here. (Sandy Poremba)
