General SEDD Notes

Source Files

The Kansas Hospital Association provides HCUP with a combined outpatient file with ambulatory surgery (AS) and emergency department (ED) records from acute care general hospitals. The Kansas outpatient file contains information on the following types of outpatient services, which are identified by an outpatient place of service indicator:

  • Emergency room (1)
  • Outpatient surgery (2)
  • Observation only (3)
  • Rural health clinic (4)
  • Other outpatient clinic (5)
  • Physician's clinic (6)
  • Other outpatient (9)

Selection of Records for Inclusion in the SEDD

All records identified by Kansas as ED are included in the SEDD (HCUP data element STATE_ED=1 based on outpatient place of service for emergency room).

Additionally, any other records with evidence of ED services that are flagged by the variable HCUP_ED (i.e., HCUP_ED>0) during HCUP processing are included in the SEDD. If a record in the SASD also has evidence of ED services based on the HCUP criteria (HCUP data element HCUP_ED not equal to 0), then the SASD record is also included in the SEDD. These records will have the same value for the HCUP data element KEY.

SEDD records with evidence of other types of outpatient services, such as observation, can be identified by the data element OPService.

Types of Facilities Included in the Files Provided to HCUP by the Partner

The Kansas Hospital Association collects emergency department data from all hospital-owned EDs in the State.

A comparison of the number of hospitals included in the SEDD and the number of hospitals reported in the AHA Annual Survey is available starting in data year 2010.

Hospital-owned EDs do not always report data for a full calendar year. Some open or close during the year; others have technical problems that prevent them from reporting data for all months in a year.

Exclusion of Records During HCUP Data Processing During HCUP Data Processing

Beginning with 2016 data, records with a discharge disposition of "still a patient" are retained in the HCUP SEDD. Prior to 2016 data, these records were excluded. Additionally, prior to 2010, records with a discharge disposition of "admitted as an inpatient" were also excluded from the files.
