Catheter\u2010based reflux testing is currently the standard modality in Australia. Although associated with improved patient tolerability, wireless testing remains limited by access and funding restrictions.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>A cost\u2013utility analysis was conducted to compare the cost\u2010effectiveness of wireless versus catheter\u2010based reflux monitoring before anti\u2010reflux surgery. Health service costs (administrative, labour, and equipment) and EuroQol 5\u2010Dimension\u2010derived utility weights were used to calculate incremental costs per quality\u2010adjusted life\u2010year (QALY) over a one\u2010year time horizon.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Wireless pH monitoring was associated with marginally lower costs and higher QALYs compared with catheter\u2010based monitoring (AUD $11001.51 vs. AUD $11210.47; 0.87 vs. 0.82 QALYs). The base\u2010case incremental cost\u2010effectiveness ratio was \u2212AUD $5026.64 per QALY, indicating that wireless monitoring was the dominant strategy. At a willingness\u2010to\u2010pay threshold of AUD $50\u2009000 per QALY, the incremental net monetary benefit was AUD $2287.47, indicating potential cost\u2010effectiveness.
