Background: The aim of this study was to perform a validity analysis of the Turkish version of the Catheterization Risk Score for Pediatrics.

Methods: The study sample consisted of 419 pediatric patients who underwent cardiac catheterization. Patient risk factors and outcomes were collected using the revised (r) Catheterization Risk Score for Pediatric score (21 points) and Catheterization Risk Score for Pediatric score-20 point (Nykanen score). The serious adverse events and non-serious adverse event complications that occurred during and after the procedure were recorded. The revised Catheterization Risk Score for Pediatrics and Catheterization Risk Score for Pediatrics score-20 points were administered by pediatric cardiologists. The content validity index was calculated based on expert opinions. Chi-square, correlation, and regression analyses were used.

Results: The mean age of the pediatric patients was 4.5 ± 4.8 years. Of the patients, 50.1% were male (n = 210) and 85% (n = 356) had acyanotic heart disease. The patients’ Catheterization Risk Score for Pediatrics score-20 point and revised Catheterization Risk
Score for Pediatrics score were 5.9 ± 2.5 (range, 3-16) and 4.0 ± 2.5 (range, 0-16), respec-tively. Serious adverse events developed in 10.7% (n = 45) of the patients and were found to be related with patient status/timing of catheterization, age, weight, respiratory status, and American Society of Anesthesiologist scores (P <.05). Significant positive cor-relations were found between the incidence of serious adverse events and total revised Catheterization Risk Score for Pediatrics score (21 points), total Catheterization Risk Score for Pediatrics score-20 point, and American Society of Anesthesiologist score (P <.01).

Conclusion: The revised Catheterization Risk Score for Pediatrics score (21 points) and Catheterization Risk Score for Pediatrics score-20 point are valid tools for predicting pre-procedural risk in the Turkish population.
