Early referral for catheter-based esophageal pH monitoring is more cost-effective than empiric proton-pump inhibitor (PPI) therapy to diagnose gastroesophageal reflux disease (GERD). We hypothesize that BRAVO wireless pH monitoring will also demonstrate substantial cost-savings compared to empiric PPI therapy, given its superior sensitivity and comfort. We reviewed 100 consecutive patients who underwent wireless pH monitoring for suspected GERD at our institution. A cost model and a cost equivalence calculation were generated. Cost-saving analyses were performed for both esophageal and extraesophageal symptoms. Eighty-seven patients were available for analysis. Median PPI use prior to referral was 215 weeks (range 0-520). Forty-three patients (49 %) had BRAVO results diagnosing GERD; 98 % of these had esophageal symptoms. Patients with negative BRAVO studies had a median of 113 (0-520) weeks of unnecessary PPI therapy. Cost-savings ranged from $1048 to $15,853 per patient, depending on sensitivity (75-95 %), PPI dosage, and brand. Maximum cost-savings occurred in patients with extraesophageal symptoms ($2948-$31,389 per patient). The PPI cost equivalence of BRAVO placement was 36 and 6 weeks for low- and high-dose therapy, respectively. BRAVO wireless pH testing is more cost-effective than prolonged empiric medical management for GERD and should be incorporated early in the treatment algorithm.
