Oregon Hospital Discharge Data Dashboard

Welcome

The Oregon Hospital Discharge Data Dashboard allows users to explore trends in the number of people discharged (i.e., released) from Oregon hospitals and the length of time people stayed in the hospital in both the inpatient and emergency settings. Hospital discharge is a widely used measure of hospitalization because it most accurately encompasses overall care within one visit to the hospital, generally including all services provided to a patient from the time of admission to the time the patient is discharged from the hospital. The dashboard includes: 

  • Statewide trends in discharges and length of stay, overall and by patient characteristics 
  • Individual hospital trends in discharges and length of stay, overall and by primary payer
  • Trends in common diagnoses or reasons for hospitalization, including deliveries and mental health or substance use disorder diagnoses
  • Comparisons in length of stay by hospital, by discharge location, and by mental health or substance use disorder diagnoses 
  • Average emergency department admissions and length of stay by day of the week and by time of day 

The dashboard is updated quarterly, typically by the end of February, May, August, and November.

The Dashboard

Please allow a few moments for the dashboard to load.

Use the dropdown filters to modify the data. Learn what the filter options mean under "Terminology" below.


Terminology

Quarter 1 (Q1) includes January through March, Quarter 2 (Q2) includes April through June, Quarter 3 (Q3) includes July through September, and Quarter 4 (Q4) includes October through December.​

​Emergency data only includes patients who were treated in and discharged from the emergency department. Patients who first received services in the emergency department and were then admitted to the same hospital are ​​​only included in the inpatient data, not the emergency data.​

Length of stay is the amount of time from a patient being admitted to the hospital to a patient being discharged. In the inpatient setting, length of stay is measured in days. In the emergency setting, length of stay is measured in hours. Because length of stay in the emergency setting begins when a patient checks in, emergency length of stay includes both the time a patient spends in the waiting area and the time spent receiving evaluation and treatment.

Longer lengths of stay affect patient experience when patients encounter long wait times in the emergency setting or added hospital days in the inpatient setting. Additionally, longer lengths of stay in the emergency setting, particularly longer than 8-12 hours, can indicate that patients are not accessing needed care, such as inpatient admission or transfer to another hospital, in a timely manner. Longer lengths of stay in the inpatient setting, generally 7 days or more, can indicate that patients require a discharge location that can provide a certain level of care, such as a nursing facility, and cannot be placed in a timely manner.​​

​​​Payer refers to the line of business of the primary payer for the hospital stay: Medicaid, Medicare fee-for-service (FFS), Medicare Advantage, commercial, other, or uninsured. ​

Other includes all other types of coverage, including Veterans Affairs, TRICARE, Worker’s Compensation, Indian Health Service, and other government programs. 

All additional payers refers to the combination of all additional lines of business not otherwise listed for a particular hospital in a particular time period. This category is used to aggregate multiple payers with small numbers of discharges to prevent the disclosure of small numbers and protect patient privacy. All additional payers can include discharges in which the patient was uninsured.

​​ The race and ethnicity data fields in the Hospital Discharge Data (HDD) follow the 1997 Office of Management and Budget (OMB) standards​. They are not compliant with the updated 2024 OMB standards or the 2024 OHA Race, Ethnicity, Language, and Disability (REALD) and Sexual Orientation and Gender Identity (SOGI) collection standards. Hospitals collect and report race and ethnicity data according to the standards specified by the federal Office of Management and Budget, and these standards are not REALD and SOGI compliant.​

The race and ethnicity fields are combined in the data for this dashboard using a least common race/ethnicity methodology. If the HDD race field is Native Hawaiian or Pacific Islander, American Indian or Alaska Native, Asian, or Black or African American, then the combined race/ethnicity is the HDD race. If the HDD ethnicity field is Hispanic or Latino and the HDD race field is white, other, patient refused, or unknown, then the combined race/ethnicity is Hispanic or Latino. If the HDD ethnicity field is not Hispanic or Latino and the HDD race field is white, other, patient refused, or unknown, then the combined race/ethnicity is the HDD race. 

"Other" indicates that the patient answered that their race is another category not listed (a category other than American Indian or Alaska Native, Asian, Black or African American, Native Hawaiian or Pacific Islander, or White). Patient Refused indicates that the patient declined to answer the question regarding their race. Unknown indicates that recording the patient’s answer to the question regarding their race was “unattainable due to other circumstances.”

​Record indicates homelessness means that one of the ICD-10 condition codes for homelessness (Z590, Z5900, Z5901, or Z5902) is present in any of the diagnosis fields for that discharge record. Not every patient experiencing homelessness will necessarily have one of these codes on their discharge record, meaning that this definition likely results in an undercount of the number of hospital discharges among people experiencing homelessness.​

​ALF/ICF/other nursing f​acility is a discharge location category that includes assisted living facilities (ALF), intermediate care facilities (ICF), and nursing facilities with neither Medicare nor Medicaid certification (other nursing facility).​

Received ED services before admission refers to inpatient discharge records that indicate that a patient first received services in the emergency department (ED) and was then admitted to the same hospital. 

Patients who receive ED services before inpatient admission typically come to the ED with a serious, potentially life-threatening condition that requires further treatment in the inpatient setting. Patients who do not receive ED services before inpatient admission generally had a planned admission for a particular procedure, were admitted with a serious condition from another health care setting such as a doctor's office, or were transferred from another hospital.


​ Hospital type includes DRG, Type A, Type B, and S hospitals. DRG hospitals are large, urban hospitals. Type A are small hospitals (50 or fewer beds) located more than 30 miles from another hospital. Type B are small hospitals (50 or fewer beds) located within 30 miles of another hospital. While not an official hospital type designation, S indicates a specialty hospital. Currently, the only type S hospital is Legacy Unity Behavioral Health, a specialty psychiatric hospital in Portland.

For more information, please refer to the Oregon Hospital Types guide​.

​Deliveries include both vaginal deliveries (MS-DRGs 767, 768, 774, 775, 796, 797, 798, 805, 806, and 807) and cesarean section deliveries (MS-DRGs 765, 766, 783, 784, 786, 787, 785, and 788).​

Please refer to the Small Number Suppression section for details on how delivery data is presented to avoid disclosing counts smaller than 10.

​Please note that the abbreviation "dx" is used for "diagnosis" in these category names.

Diagnosis level: Primary diagnosis on the discharge record

  • Mental health primary dx refers to discharge records with a mental health condition diagnosis code as the primary diagnosis.

  • SUD primary dx refers to discharge records with a substance use disorder (SUD) diagnosis code as the primary diagnosis.

  • Mental health or SUD primary dx refers to discharge records with either a mental health condition diagnosis code or a substance use disorder diagnosis code as the primary diagnosis. This is an umbrella category used when further disaggregating into the two categories listed above could result in fewer than 10 total discharges in a category and risk patient privacy.

  • Primary dx not mental health or SUD refers to discharge records with a primary diagnosis unrelated to a mental health condition or a substance use disorder.

Diagnosis level: All diagnoses on the discharge record 

​​​​​​​​The mental health and substance use disorder categories listed ​below include records with rele​va​nt codes in any diagnosis field, covering b​oth primary and additional diagnoses. This means that for many of the records in these categories, a mental health condition and/or substance use disorder was present but was not the primary reason for the hospitalization or emergency department visit.

  • ​​Mental health dx + no SUD dx refers to discharge records with at least one diagnosis code related to a mental health condition and no diagnosis codes related to a substance use disorder (SUD). 

  • SUD dx + no mental health dx refers to discharge records with at least one diagnosis code related to a substance use disorder and no diagnosis codes related to a mental health condition. 

  • Mental health and SUD dx refers to discharge records with at least one diagnosis code related to a mental health condition and at least one diagnosis code related to a substance use disorder. 

  • Mental health and/or SUD dx refers to discharge records with at least one diagnosis code related to a mental health condition or at least one diagnosis code related to a substance use disorder or both. This is an umbrella category used when further disaggregating into the three categories listed above could result in fewer than 10 total discharges in a category and risk patient privacy. 

  • No mental health or SUD dx refers to discharge records with no diagnosis codes related to a mental health condition and no diagnosis codes related to a substance use disorder.

General mental health and substance use disorder information

Common mental health conditions in hospital discharge records include anxiety disorders, depressive disorders, dementia, post-traumatic stress disorder, bipolar disorder, and schizophrenia. Common substance use disorders in hospital discharge records include alcohol, opioid, and stimulant use disorders.  

For a list of specific ICD-10 diagnosis codes that make up the mental health and substance use disorder categories, please refer to the supplemental d​​​​​iagnosis code file​.

​Youth includes patients age 17 and younger at the time of admission. Adult includes patients age 18 and older at the time of admission.​

​Trends in emergency department visits and length of stay by day of the week and by time of day provide insight into patterns of emergency department use at each hospital over the most recent four quarters of data available. These trend data indicate when people are most likely to seek emergency department care and how patient volume and staffing levels at different days and times affect how long patients spend in the emergency department. Variation in patterns of emergency department use at different hospitals also indicates how access to emergency care varies depending on hospital size and region. ​


About the Data

The data source for this dashboard is the Hospital Discharge Data, a database of records of every discharge from inpatient hospitals and emergency departments in Oregon. The current version of the dashboard uses data from the 2024 Q3 update to ​the Hospital Discharge Data.​

​For more information about the data used in this dashboard, please read the Hospital Discharge Data profile​. ​​

Beginning in 2022 Q2, inpatient and emergency discharges from the Redmond campus of the St. Charles Medical Center are no longer reported under St Charles - Redmond. They are instead reported under St Charles - Bend. 

The emergency department at PeaceHealth Sacred Heart Medical Center - University District closed on December 1, 2023. 

The last inpatient discharge reported at PeaceHealth Sacred Heart Medical Center - University District was on December 15, 2023. 

Prior to November 2019, Hillsboro Medical Center was known as Tuality Community Hospital. The dashboard refers to this hospital as Hillsboro Medical Center throughout. 

Prior to June 2023, Adventist Health Columbia Gorge was known as Mid-Columbia Medical Center. The dashboard refers to this hospital as Adventist Health Columbia Gorge throughout. 

Legacy Unity Behavioral Health is a specialty psychiatric hospital. It provides inpatient services to patients age 9 and older, and its emergency department serves adults age 18 and older.

​​In line graphs of discharge counts by quarter, discharge counts smaller than 10 are excluded from the graphs and left blank. In line graphs of average length of stay by quarter, average lengths of stay are excluded from the graphs and left blank if there were fewer than 5 discharges in that quarter.

In graphs of discharge counts by payer, payer categories with small discharge counts are combined into an All additional payers category to prevent the disclosure of counts smaller than 10. 

In the Diagnoses: Deliveries tabs, some hospitals have only Medicaid and All additional payers as payer categories. In these cases, either the count of commercial deliveries or the combined count of other coverage, uninsured, and Medicare deliveries is smaller than 10, so deliveries for all payers other than Medicaid have been included in All additional payers to prevent the disclosure of counts smaller than 10.

In the Diagnoses: Deliveries tabs, if counts of deliveries for Medicaid, commercial, and/or all additional payers are smaller than 10 at a particular hospital, then counts of deliveries are not disaggregated by payer in order to prevent the disclosure of counts smaller than 10. Total delivery counts for these hospitals are presented as All payers combined. Because total delivery counts are not disaggregated by payer for these hospitals, these hospitals are excluded from the graph of delivery percent by hospital and payer on the tab Deliveries: all hospitals.

Similarly, in the Deliveries: hospital trends tab, if counts of either C-section or vaginal deliveries are smaller than 10 at a particular hospital in a particular year, then counts of deliveries are not disaggregated by delivery type in order to prevent the disclosure of counts smaller than 10. Total delivery counts for these hospitals and years are presented as All deliveries combined.​

In the Diagnoses: Mental health + SUD by hospital tab, hospitals with fewer than 10 discharges with mental health or SUD diagnoses for the selected diagnosis level (primary diagnosis or all diagnoses on the discharge record) are excluded from the discharge count and percent graphs.

Legacy Unity Behavioral Health, a specialty psychiatric hospital, is excluded from the Diagnoses: Mental health + SUD by hospital tab because nearly all discharges from this hospital involve mental health or substance use disorder diagnoses.

In the Length of stay: By hospital tab, discharge counts smaller than 10 are excluded from the table and tooltips and left blank. To prevent back-calculation, the next smallest discharge count for that particular hospital is also excluded and left blank.​

In the ED utilization tabs, average admissions smaller than 10 are labeled as 1-9.​

​Due to a reporting error that has since been resolved, there are 3,000-6,000 fewer emergency discharge records than expected in 2023 Q2 for Adventist Medical Center.​
