Key result
Low Rank Matrix Decomposition outperforms non-negative matrix factorization in identifying pediatric asthma with 84% sensitivity.
Why the study?
Early identification of pediatric patients at high risk of developing asthma is challenging due to large data sets and lack of complex analysis or clinical logic determination.
Can an asthma prediction model using low rank matrix decomposition identify pediatric patients at high risk of developing asthma?
Can an asthma prediction model using low rank matrix decomposition identify pediatric patients at high risk of developing asthma?

A low rank matrix decomposition model using APR-DRGs coding assignments was developed to predict asthma risk in pediatric patients.
Asthma is a prevalent disease in pediatric patients and most of the cases begin at very early years of life in children. Early identification of patients at high risk of developing the disease can alert us to provide them the best treatment to manage asthma symptoms. Often evaluating patients with high risk of developing asthma from huge data sets (e.g., electronic medical record) is challenging and very time consuming, and lack of complex analysis of data or proper clinical logic determination might produce invalid results and irrelevant treatments. In this article, we used data from the Pediatric Research Database (PRD) to develop an asthma prediction model from past All Patient Refined Diagnosis Related Groupings (APR-DRGs) coding assignments. The knowledge gleamed in this asthma prediction model, from both routinely use by physicians and experimental findings, will become fused into a knowledge-based database for dissemination to those involved with asthma patients. Success with this model may lead to expansion with other diseases.

Teeradache Viangteeravat (2013) studied Pediatric asthma (n=7,011). Low Rank Matrix Decomposition (LRMD) vs. Non-negative matrix factorization (NMF) was evaluated on Sensitivity and specificity for asthma identification. The Low Rank Matrix Decomposition model identified pediatric asthma patients with a sensitivity of 0.84 and specificity of 0.76 at a cutoff score > 0.75, outperforming non-negative matrix factorization.
