Accuracy of Condition Present on Admission, Do Not Resuscitate, and E-Codes in California Patient Discharge Data

The California Office of Statewide Health Planning and Development (OSHPD) contracted with the University of California, San Francisco to produce a report on the quality of hospital data coding in the California Patient Discharge Dataset (PDD) produced by OSHPD. To accomplish this, contractors conducted on-site medical chart reviews at 48 California hospitals for approximately 1,600 records of patients hospitalized in 2005 with one of three medical conditions (acute myocardial infarction, congestive heart failure, or community-acquired pneumonia) or the procedure percutaneous transluminal coronary angioplasty.

The report focuses on the validity and reliability of three data element types:

  1. The Condition Present on Admission (CPOA) indicator, used to distinguish patient conditions existing prior to admission from those acquired post-admission
  2. Do Not Resuscitate (DNR) order
  3. Injury E-Codes indicating location/site of injury

The study also provides information on the reliability of most other data elements in the PDD.
