Observation visits are classified as outpatient care and serve a variety of functions, including the reassessment of clinical status and/or continued testing beyond the care provided in an emergency department. Acute care hospitals submit data quarterly to CHIA’s Case Mix databases including information on patient socio-demographics, diagnostic information, treatment and service information, and hospital charges.
In the February 2025 quarterly update, data on statewide visits and average length of stay by hospital system was been added under the statewide utilization section.
The current dashboard relies on interim and final annualized data to present analyses on a quarterly basis from October 2019 through December 2025. The data in the quarterly updates are preliminary.
