Poliomyelitis v1

Query purpose: 

Created by the CDC National Syndromic Surveillance Program (NSSP) for use with ED data as part of the rapid reportables project, which seeks to create queries for all National Notifiable Diseases defined by the National Notifiable Diseases Surveillance System (NNDSS). This query is intended to be a version 1 and may be further improved upon by the NSSP community of practice in the future. This query is intended to be narrow and capture visits with specific terms to support greater monitoring and actionable public health data. More complex and/or broader queries may exist that more broadly capture symptoms or travel-based terms.

How it was developed: 

  1. The CDC team used the NNDSS case definition for paralytic poliomyelitis to identify diagnostic codes (International Classification of Diseases, 9th & 10th Revisions (ICD-9-CM, ICD-10-CM), SNOMED Clinical Terms (CT)) and chief complaint free text for syndrome development.
  2. The codes and free text were then categorized as inclusion or exclusion terms. These terms were formatted for querying in ESSENCE.
  3. Text analysis was conducted on the initial query to find additional inclusion or exclusion terms.
  4. The query was cross-checked internally by NSSP and by CDC subject matter experts as needed.

How it works:

The Chief Complaint Discharge Diagnosis (CCDD) parsed field is used to query both the discharge diagnosis codes and chief complaint free text.

  • Inclusion based on paralytic polio-related chief complaint free-text terms:
    • The visit is included if it contains:
      1. Chief complaints related to the pathogen name – (“polio”, “poliomyelitis”) OR
  • Inclusion based on ICD-10 discharge diagnosis codes related to paralytic polio:
    • The visit is included if it contains:
      1. A discharge diagnosis code of Acute paralytic poliomyelitis (A80) OR
  • Inclusion based on ICD-9 discharge diagnosis codes related to poliomyelitis:
    • The visit is included if it contains:
      1. A discharge diagnosis code of Acute paralytic poliomyelitis specified as bulbar (045.0) OR
      2. A discharge diagnosis code of Acute poliomyelitis with other paralysis (045.1) OR
      3. A discharge diagnosis code of Acute nonparalytic poliomyelitis (045.2) OR
      4. A discharge diagnosis code of Unspecified acute poliomyelitis (045.9) OR
  • Inclusion based on SNOMED CT discharge diagnosis codes related to acute hepatitis B:
    • The visit is included if it contains:
      1. A discharge diagnosis code of Acute poliomyelitis (398102009) OR
      2. A discharge diagnosis code of Polio encephalitis (192686004) OR
      3. A discharge diagnosis code of Acute paralytic poliomyelitis (240460008) OR
      4. A discharge diagnosis code of Acute paralytic non-bulbar poliomyelitis (186476008)
      5. A discharge diagnosis code of Acute nonparalytic poliomyelitis (14535005) OR
      6. A discharge diagnosis code of Acute nonparalytic poliomyelitis caused by human poliovirus 1 (429297003) ANDNOT
  • All of the above must exclude:
    • Chief Complaint terms related to history of polio or encounter for polio vaccination – (,"history of polio", "history polio", "HX of polio", "polio as a child", "polio as a kid", "polio as child", "polio as kid", "booster", "vaccin", "shot", "immuniz", "prophy", "post polio", "encounter for", "follow up") OR
    • ICD-10 discharge diagnosis codes related to history of polio or encounter for vaccination:
      1. A discharge diagnosis code of Sequelae of poliomyelitis (B91) OR
      2. A discharge diagnosis code of Postpolio syndrome (G14) OR
      3. A discharge diagnosis code of Encounter for immunization (Z23) OR
      4. A discharge diagnosis code of Personal history of poliomyelitis (Z86.12) OR
    • SNOMED discharge diagnosis codes related to history of polio or encounter for vaccination:
      1. A discharge diagnosis code of History of poliomyelitis (161415006) OR
      2. A discharge diagnosis code of Sequela of infection caused by Human poliovirus (110270004) OR
      3. A discharge diagnosis code of Administration of vaccine product containing only Human poliovirus antigen (72093006) OR
      4. A discharge diagnosis code of Post poliomyelitis syndrome (31097004)
