Finally, since our study used a hospitalization database, these results may not be generalizable to all dermatomyositis patients who are typically managed in the outpatient setting.
We had access to data from the discharge abstract database (DAD), a hospitalization database used in all adult hospitals in Calgary, Alberta, Canada, to test the previously published and new case definitions for depression.
In summary, we have validated a hospitalization database for the identification of patients with acetaminophen overdose and associated hepatotoxicity.
In addition, currently there is no regular reporting of standardized and comparable hospital-based indicators in Lebanon [ 11], and the MoPH is interested in using its hospitalization database to develop outcome or proxy indicators.
Using a population-based, hospitalization database, we determined that the principal diagnostic codes for acetaminophen overdose (ICD-9-CM, 965.4; ICD-10, T39.1) had the optimal operating characteristics for case identification.
Therefore, the objectives of our study were: 1) to determine the validity of ICD-9-CM and ICD-10 diagnostic codes for acetaminophen overdose and hepatotoxicity using a population-based, hospitalization database; and 2) to derive accurate coding algorithms for the identification of these diagnoses for use in future studies employing administrative data.
We identified infants using the KPNC hospitalization database and the Neonatal Minimum Data Set [ 23], a database that captures supplemental oxygen use and assisted ventilation among infants receiving neonatal intensive care.
Retrospective cohort study using the national hospitalization database of patients older than 15 years admitted to public hospitals from 2005 to 2010.
