摘要: OBJECTIVES The aim of the study was to determine extent agreement between pH paper and handheld meter with a laboratory for gastric measurement in children neurologic impairments gastrostomy tubes who have gastroesophageal reflux disease (GERD). METHODS In this prospective observational study, contents were aspirated from or nasogastric measured using 3 techniques: paper, meter, (the gold standard). Agreement techniques assessed intraclass correlation coefficient (ICC), Bland-Altman analysis, kappa statistic. RESULTS Among 43 patients contributing 67 samples, ICC 0.75 (95% confidence interval [CI]: 0.69-0.97) meters, 0.69 CI: 0.63--0.94) 0.63-0.94) paper. analysis lab meters showed mean difference -0.03 units (limits agreement: -0.52 0.47 units) 0.17 -0.99 1.33 meter. coefficients ≥4 1.0 1.0--1.0) 0.9 0.77--1.0) CONCLUSIONS findings suggest that both point-of-care tests, correlate well standard testing indicating usefulness monitoring tube-fed GERD.
