The PC-Log computerized perinatal database shows good agreement for many clinical variables, but has limitations for others like maternal ethanol use. Data accuracy is crucial for electronic birth certificates.

Area of Science:

  • Perinatal medicine
  • Health informatics
  • Clinical data management

Background:

  • Computerized perinatal databases are essential for electronic birth certificate transmission.
  • Assessing the accuracy of clinical data in these systems is vital for reliable healthcare information.
  • The PC-Log system is utilized in Wisconsin for perinatal data collection.

Purpose of the Study:

  • To evaluate the clinical data accuracy of the PC-Log computerized perinatal database.
  • To compare data in PC-Log against paper medical records for correctness.
  • To identify specific variables with high and low agreement in the database.

Main Methods:

  • A random sample of 99 charts was selected from 893 births at a tertiary perinatal center.
  • 32 key variables from the PC-Log database were compared to hand-abstracted data from paper medical records.

  • Positive-predictive value (PPV), sensitivity, and specificity were calculated for various clinical variables.

    • Main Results:

    • PC-Log demonstrated 100% PPV for eclampsia, prolonged rupture of membranes, pre-existing diabetes, cesarean section, and transports.
    • Moderate to high agreement was observed for variables including abortion, congenital anomalies, gestational diabetes, maternal hypertension, and maternal employment.
    • Poor agreement was noted for maternal ethanol use, and PC-Log lacked data on substance abuse and length of stay.

    Conclusions:

    • The PC-Log system exhibits good agreement for many clinical variables, supporting its use in perinatal data collection.
    • Limitations exist for certain variables, necessitating careful review and potential improvements in data abstraction.
    • While birth weight and Apgar scores showed strong correlation, the database requires further validation for comprehensive clinical accuracy.
