Validating Recipients of Pediatric Solid Organ Transplant Using Administrative Healthcare Data

Area of Science:

• Pediatric Solid Organ Transplantation
• Health Services Research
• Data Validation

Background:

• Health administrative datasets offer potential for pediatric solid organ transplantation research.
• Validation of these datasets is crucial for ensuring accuracy in research findings.
• This study focuses on a major pediatric transplant center in Ontario, Canada, from 1991-2011.

Purpose of the Study:

• To assess the validity of administrative data for identifying pediatric solid organ transplant recipients.
• To compare administrative data accuracy against direct transplant records.

Main Methods:

• Retrospective analysis of linked administrative healthcare databases.
• Evaluation of physician billing claims and hospital diagnostic/procedural codes.
• Calculation of sensitivity and positive predictive value (PPV) for various algorithms.

Main Results:

• A total of 347 kidney, 250 liver, 200 heart, and 28 lung transplants were analyzed.
• Hospital procedural codes from the Canadian Institute for Health Information Discharge Abstract Database showed the highest accuracy.
• The best algorithm achieved 91% sensitivity and 93% PPV for all organ types combined.

Conclusions:

• This study validates administrative data for identifying pediatric solid organ transplant recipients.
• Procedural codes demonstrate reliability for population-level health research in pediatric transplantation.
• Findings support the use of administrative data in future pediatric transplant studies.
