Notes: |
1Categories of principal diagnosis were defined by grouping ICD‐10‐CM codes using the Clinical Classifications Software Refined (CCSR) into clinically meaningful categories. CCSR was developed by the Healthcare Cost and Utilization Project (HCUP), which serves as the central distributor of hospital data for the Agency for Healthcare Research and Quality (AHRQ). Average Length of Stay (ALOS): This statistic indicates the number of days of care accumulated at the time of discharge by patients hospitalized during the year, divided by the number of these hospitalizations. ‐: A dash (‐) indicates quantity zero (0). *: An asterisk (*) indicates that the data do not meet standards of reliability or precision. |
