|Description:||The Hospital Data Project (HDP) of the European Union Health Monitoring Programme convened an Expert Group to create a “shortlist” of clinical conditions that could be monitored across countries based on the special tabulation list for morbidity published in ICD-10 volume one. The special tabulation list grouped diagnosis codes into 298 categories, so that these categories could be compared across hospitals world-wide. However, this list was regarded to be extensive and difficult to use for analytical purposes. Therefore, the International Shortlist for Hospital Morbidity Tabulation (ISHMT) was created and represents a subset (130) of the original 298 categories.|
|Purpose/Use:||The purpose of the ISHMT is to provide a means by which to compare hospital morbidity statistics across hospitals world- wide in a manner that maximizes statistical comparability and efficiency.1|
|Coding Family:||ICD-9 & ICD-10|
Select diagnoses codes are grouped into one of 130 ISHMT categories. The 130 categories are comprised of:
This grouping system is hierarchical and can be collapsed into ICD-10 chapters.
|Level of Diagnosis Aggregation:||Diagnoses are grouped into 130 categories.|
|Number of Codes Included:||Not specified|
|Number of Codes Excluded:||Not specified|
|Methodological Considerations:||This grouping system provides a means by which to compare hospital morbidity statistics across hospitals world-wide in a manner that maximizes statistical comparability. However, this grouping system represents only a subset of the clinical conditions that were identified based upon expert consensus. In addition, differences in diagnostic cultures and coding practices among countries are a general limitation of this grouping system.|
