Year Filter: 2021
Data Grouped By:Year
The hospitalization data in the NJSHAD system only include discharges of New Jersey residents from New Jersey hospitals.

The Emergency Department Database contains information on ED visits that do not result in admission to the same hospital (i.e., "treated and released," which includes patients who were discharged home, transferred to another health care facility, left against medical advice, left without being seen, transferred to another hospital, or died).

The International Classification of Diseases (ICD) is a coding system maintained by the World Health Organization and the U.S. National Center for Health Statistics. It is used to classify causes of death on death certificates and diagnoses, injury causes, and medical procedures for hospital and emergency department visits. These codes are updated every decade or so to account for advances in medical technology. The U.S. is currently using the 10th revision (ICD-10), however the 9th revision (ICD-9) was used for hospital and emergency department visits through September 30, 2015. New Jersey's October 1 - December 31, 2015 records have been back-coded to ICD-9.

The Uniform Billing (UB) database contains billing information and charges for services received, diagnosis and procedure codes following the International Classification of Diseases (ICD), and patient demographic information. The data are primarily designed for billing purposes and are reported for each episode of care.

The Office of Health Care Quality Assessment (HCQA) receives patient level hospital discharge data on a monthly basis through its data intermediary and provides the file "as is." The data are not audited and researchers should exercise caution when interpreting findings from analyses of these data. 

Due to a change in population estimation methodology at the U.S. Census Bureau, rates for 2020 and later are not directly comparable to rates from before 2020. After 2010-2020 intercensal estimates are released by the Census Bureau in late 2024, all rates will be recalculated to enable trend analysis.
