Positive predictive value of congenital heart disease diagnostic codes in the Danish National Patient Registry.

ABSTRACT:

Background

Congenital heart disease (CHD) is a public health concern as the most common birth defect with growing prevalence in adults. Valid CHD data are critical in clinical epidemiological CHD research.

Objectives

To evaluate the positive predictive value (PPV) of having a CHD diagnosis and related surgery registered in the population-based Danish National Patient Registry (DNPR) according to the International Classification of Diseases, 8th and 10th revision, using predefined exclusion criteria to increase diagnostic validity.

Methods

Using medical record review as reference standard, we computed the PPV of registered diagnostic codes for CHD and CHD subtypes including 95% confidence intervals (CIs) as well as the PPV of presence of CHD-related surgery. A sample o
