Objective<\/strong> — To evaluate the accuracy of diagnostic algorithms developed using the International Classification of Diseases (ICD-9-CM and ICD-10-CA) diagnostic codes and physician billing codes for thromboembolism (TE) from health administrative data compared to chart review diagnoses of TE in children with cancer.<\/p>\n

Methods<\/strong> — Using data linkage between the Pediatric Oncology Group of Ontario Network Information System (Ontario pediatric cancer registry) and various administrative data housed at ICES, eight algorithms were developed including a single reference to one of the billing codes, multiple references with varying time intervals, and combinations of various billing codes during primary cancer therapy for the whole cohort and, for early (<04\/2002) and later (\u226504\/2002, solely ICD-10 codes) periods. Reference standard was chart review data from prior studies (from 1990 to 2016) among children (\u226419 years) with cancer and radiologically confirmed TE.<\/p>\n

Results<\/strong> — Records of 2056 patients diagnosed with cancer at two participating sites during study period were reviewed; 112 had radiologically confirmed TE. The algorithm with addition of anticoagulation utilization codes was the best performing algorithm (sensitivity\u2009=\u20090.76;specificity\u2009=\u20090.85). With use of ICD-10 only codes, sensitivity of the same algorithm improved to 0.84 with specificity of 0.80.<\/p>\n

Conclusion<\/strong> — This study provides a valid approach for ascertaining pediatric TE using real-world data.<\/p>\n","protected":false},"excerpt":{"rendered":"
