Maternal morbidity in cases of placenta accreta managed by a multidisciplinary care team compared with standard obstetric care.

Objective: To compare maternal morbidity in cases of placenta accreta managed by a multidisciplinary care team with similar cases managed by standard obstetric care.

Methods: This was a retrospective cohort study of all cases of placenta accreta identified in the State of Utah from 1996 to 2008. Cases of placenta accreta were identified using International Classification of Diseases (ICD-9) codes for placenta accreta, placenta previa, and cesarean hysterectomy.

Performance of International Classification Of Diseases, 9th Revision, Clinical Modification codes as an adverse drug event surveillance system.

Background: Adverse drug events (ADEs) are one of the most frequent causes of iatrogenic injury. Because International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9-CM) codes are routinely assigned to inpatient discharges, they could provide a method to detect ADEs within a hospital, a state, and the nation.

Objective: The objective of this study was to determine validity of selected ICD-9-CM codes in identifying inpatient ADEs.
