THE KNOWLEDGE REPOSITORY HAS BEEN UPDATED TO INCLUDE CDC STIMULANT OVERDOSE V3 - THE UPDATED SYNDROME DEFINITION CAN BE FOUND HERE.
States currently funded by CDC’s Enhanced State Opioid Overdose Surveillance (ESOOS) program have been monitoring opioid overdose trends in their states. Within the last year, they started to notice increases in overdose visits related to stimulant use. Because CDC had worked with these states to develop syndrome definitions for heroin and opioid overdose, they decided to also develop a syndrome definition for stimulant overdose. CDC scientists first started developing the definition using guidance from CSTE and SAMSHA. They then built the query using a similar process to the opioid and heroin query development. First, discharge diagnosis codes and SNOMED indicating an acute stimulant poisoning were identified. Next, we used the same “overdose terms” used previously with the opioid and heroin query. Finally, we identified “drug terms” indicating that a stimulant was involved in the overdose. Similar to the opioid and heroin queries, we use both the discharge diagnosis codes/SNOMED and chief complaint free text with exclusions (as necessary). If discharge diagnosis code/SNOMED indicating a stimulant poisoning is present, the ED visit is automatically included in the syndrome. If there is no discharge diagnosis code/SNOMED present for stimulant poisoning, the visit is only included if the chief complaint text has both an “overdose” and “drug” term. In addition, the list of exclusions are only applied to the chief complaint text when a discharge diagnosis code is not present. With the opioid query, CDC identified several non-poisoning ICD-10-CM codes for inclusion in the syndrome definition (e.g., F11 codes). CDC also explored the inclusion of the stimulant-related F codes (i.e., F14 and F15) in this definition. However, our analysis showed that these codes were not identifying acute overdose visits and instead were being coded correctly as “stimulant abuse” etc. The team attempted to identify most drug names used for stimulants; however, it’s likely that some drug names and slang terms should be added to a revision definition. For example, the term “molly” (and spelling variations) used as a slang for ecstasy, should be considered in future revision.
