|General SASD Notes|
Types of Ambulatory Surgery and Other Outpatient Services Collected by the Partner
Beginning in data year 2014, MHA creates four separate indicator flags that identify ambulatory surgery, imaging services, emergency department (ED) visits, and observation services. MHA defines the ambulatory surgery flag using the following criteria:
The assignment of an ambulatory surgery and ED visit record is hierarchical. Specifically, if the Partner-defined ED flag is true, the ambulatory surgery flag is set to false. However, if an ambulatory surgery record also had observation and/or imaging services, all outpatient services will be identified on the record by the respective indicator flags. The same is also true for any ED record with observation and/or imaging services.
From 2012-2013, MHA only created three indicator flags: ambulatory surgery, imaging services, and emergency department services. A flag for observation services was not included.
Outpatient Data File Provided to HCUP by the Partner
Selection of Records for Inclusion in the SASD
Types of Facilities Included in the Files Provided to HCUP by the Partner
Identification of Hospital-Owned Ambulatory Surgery and Other Types of Outpatient Facilities in the SASD
If the facility in the SASD does not meet any of the above criteria, it is marked as not being owned by a hospital (HOSPITAL_OWNED = 0). Not all hospitals report to the AHA, so there is a possibility that some facilities marked with HOSPITAL_OWNED=0 are hospital-owned.
From data year 1998-2018, the HCUP data element was called FREESTANDING. A facility is considered hospital-owned (FREESTANDING = 0) if any one of the following is true:
If the facility in the SASD does not meet any of the above criteria, it is marked as not being owned by a hospital (FREESTANDING = 1). Not all hospitals report to the AHA, so there is a possibility that some facilities marked with FREESTANDING=1 are hospital-owned.
Exclusion of Records During HCUP Processing
Beginning with 2017 data, records with a discharge disposition of "still a patient" are retained in the HCUP SASD. Prior to 2017 data, these records were excluded. The removal of this exclusion resulted in an increase of roughly 550,000 records.
Beginning in 2010, records with a designation of "admitted as an inpatient" are retained in the SASD, even though this rarely occurs. Prior to 2010, records with a designation of "admitted as an inpatient" were excluded from the files.
