OBJECTIVE To compare consistency of coding among professional SNOMED CT coders representing three commercial providers of coding services when coding clinical research concepts with SNOMED CT. DESIGN A sample of clinical research questions from case report forms (CRFs) generated by the NIH-funded Rare Disease Clinical Research Network (RDCRN) were sent to three coding companies with instructions to code the core concepts using SNOMED CT. The sample consisted of 319 question/answer pairs from…

SNOMED CT Coding Variation and Grouping for "other findings" in a Longitudinal Study on Urea Cycle Disorders

SNOMED CT coding variation is investigated by investigating findings reported on case report forms from a clinical research study on urea cycle disorders to find 45% of the concept description pairs were associated with two hierarchically related concepts or with the same concept, while 55% wereassociated with two unrelated concepts.

Comparison of Knowledge Levels Required for SNOMED CT Coding of Diagnosis and Operation Names in Clinical Records

Performance of SNOMED coding with clinical terms is strongly related to the knowledge level of the domain and the complexity of the clinical terms.

Qualitative analysis of manual annotations of clinical text with SNOMED CT

A qualitative analysis was conducted to identify sources of disagreements on an annotation experiment which used a subset of SNOMED CT with some restrictions, and the most frequent cause of inter-annotator disagreement was related to human issues.

Use of SNOMED CT® and LOINC® to standardize terminology for primary care asthma electronic health records

The majority of ACM elements are congruent with standardized terminology, enabling EHR interoperability, and future requests for new concepts in SNOMED CT® and LOINC® should be pursued for asthma control parameters paramount to evidence-based practice.

Medical Terminology Coding Systems and Medicolegal Death Investigation Data: Searching for a Standardized Method of Electronic Coding at a Statewide Medical Examiner’s Office *

Although all four systems offer distinct advantages and disadvantages, SNOMED CT is the most accurate for coding pathologic diagnoses, with ICD‐10 the best option for classifying the cause of death.

SNOMED CT implementation: mapping guidelines facilitating reuse of data

A clear methodology for SNOMED CT mapping is provided to enhance applicability of SNOMed CT despite incompleteness and redundancy and guidelines are presented based on an in depth analysis of 14 different EHR templates retrieved from five Danish and Swedish EHR systems.

Essential SNOMED: Simplifying SNOMED-CT and supporting Integration with Health Information Models

The role of preand post-coordinated terminology expressions are considered in the context of the current development direction of Electronic Health Records and the use of communications and knowledge repositories, and a proposed implementation form of SNOMED CT would contain only “atomic concepts” with their attendant hierarchies and relationship data.



Research Paper: Use of SNOMED CT to Represent Clinical Research Data: A Semantic Characterization of Data Items on Case Report Forms in Vasculitis Research

SNOMED CT appears well-suited for representing a variety of clinical concepts, yet is less suited for representing the full amount of information collected on CRFs.

Reliability of SNOMED-CT Coding by Three Physicians using Two Terminology Browsers

Results suggest that the reliability of SNOMED-CT coding is imperfect, and may be a function of browsing methodology, and a combination of physician training, terminology refinement, and browser improvement may help increase the reproducibility of SNomED- CT coding.

Phase II evaluation of clinical coding schemes: completeness, taxonomy, mapping, definitions, and clarity. CPRI Work Group on Codes and Structures.

No major terminology source can lay claim to being the ideal resource for a computer-based patient record, however, SNOMED International is considerably more complete, has a compositional nature and a richer taxonomy.

Evaluation of the content coverage of SNOMED CT: ability of SNOMED clinical terms to represent clinical problem lists.

SNOMED CT, when used as a compositional terminology, can exactly represent most of the terms used commonly in medical problem lists, and improvements to synonymy and adding missing modifiers would lead to greater coverage of common problem statements.

An Applied Evaluation of SNOMED CT as a Clinical Vocabulary for the Computerized Diagnosis and Problem List

This paper evaluates the breadth of SNOMED CT terms and concepts for the coding of diagnosis and problem lists by clinicians within a computerized physician order entry (CPOE) system and shows that SNOMed CT is a relatively complete standardized terminology on which to base a vocabulary for the clinical problem list.

Research Paper: Evaluation of the Clinical LOINC (Logical Observation Identifiers, Names, and Codes) Semantic Structure as a Terminology Model for Standardized Assessment Measures

The results support the adequacy of the Clinical LOINC semantic structure as a terminology model for standardized assessment measures and further clarification of the definitions, especially those related to time and property, is required.

Regional Variation in Medical Classification Agreement: Benchmarking the Coding Gap

The quality of coded data may suffer as a result of disagreement or inconsistent coding within healthcare provider organizations, in an era where physicians are increasingly called upon to enter and classify patient data via computerized medical records.

Improved coding of the primary reason for visit to the emergency department using SNOMED

SNOMED coding of the RFV is more accurate than ICD-9-CM coding, and is demonstrated to be a lexical match or synonym for 93% of the text entries, while SNOMED-RT matched 87%, and ICD, 9-CM matched 40%.

Research Paper: Integrating SNOMED CT into the UMLS: An Exploration of Different Views of Synonymy and Quality of Editing

The accuracy in the judgment of synonymy was comparable for UMLS editors and nonediting domain experts, and there was reasonable agreement between the two groups.

Representing Cardiovascular Concepts in an Electronic Health Record Using SNOMED CT®

The University of Kansas School Of Nursing implemented an electronic health record (EHR) as a teaching/learning strategy to provide students the opportunity to learn about EHRs, standardized
