Compliance With Fecal Calprotectin Testing in Pediatric Patients With Inflammatory Bowel Disease
Fecal calprotectin (FC) is a highly sensitive biomarker for inflammatory bowel diseases (IBDs). Utilization of this assay has been steadily increasing. Adherence levels for FC have, however, yet to be examined in the pediatric IBD setting. We analyzed 100 consecutive patients diagnosed with IBD between 2014 and 2015 at Texas Children's Hospital. Fifty-six percent of patients were men and median age at diagnosis was 13.7 years. Following diagnosis of IBD, 84 patients had a minimum of 1 FC requested, and 95.2% of these patients completed the test at least once. An average of 2 FCs per patient was ordered each year, and the overall compliance was 76.6%. Patients who completed the initial testing with a minimum of 3 consecutive tests were more likely to remain compliant than those who failed to perform the first lab (P < 0.001). Our findings indicate good compliance with FC testing in pediatric patients with IBD.
