Abstract
Gastrojejunal tubes are important feeding devices for children with gastro-esophageal reflux, allowing medication and feeding into the small bowel, and allowing gastric venting to prevent reflux. As with many medical devices, there are multiple manufacturers and designs, including balloon-retained tubes and disc-retained tubes. This study evaluated the cost difference between these two types of gastrojejunal tube. We conducted a 3.5-year retrospective cost evaluation for all pediatric patients undergoing an insertion or change of gastrojejunal tube using a bottom-up micro-costing analysis. We calculated days between encounters and a subsequent cost per day for each patient. A total of 187 children and adolescents were included, with an average age of 9.2years. They underwent a total of 1,240 encounters, an average of 6.6 encounters per patient during the study period. A total of 82% of these encounters were related to balloon-retained tubes and 18% to disc-retained tubes. The most common reason for an encounter was a routine change (57%), with mechanical complications accounting for 31%. Disc-retained tubes had a longer period between encounters (117.5days) than balloon-retained tubes (95days; P=0.038). However, disc-retained tubes cost 6.9 British pound sterling (GBP) per day, which was significantly higher than balloon-retained tubes at 5.2 GBP per day (P<0.0001). Despite being more expensive to purchase, balloon-retained tubes were noted to be the least costly device in a cost-per-day analysis.
