Abstract

AIMS: To evaluate the variation in tolerance to wireless pH-metry compared with catheter-based pH-metry, and to determine clinical characteristics that might predict reduced tolerance to wireless pH-metry. Methods: Consecutive outpatients (n=341) completing wireless (n=234) or catheter-based pH-metry (n=106) were evaluated. All patients completed the pH-Metry Impact Scale and the pH-Metry Symptoms Scale to assess the impact of the pH-metry on activities of daily living and pH-metry associated changes in study-related symptoms. All data are presented as mean (SD) or odds ratios (95% confidence interval). Results: The impact of pH-metry on activities of daily living were modest, but wireless pH-metry had less impact than catheter-based pH-metry (P=0.01). A sense of foreign body in the chest, chest discomfort, and chest pain were reported more frequently during wireless pH-metry. Difficulty swallowing and painful swallowing were more common during catheter-based pH-metry. Noncardiac chest pain was associated with increased symptom severity. Patients with poor tolerance were twice as likely to have a diagnosis of noncardiac chest pain (odds ratio=2. 53; 95% confidence interval, 1.4-4.6). Conclusions: Wireless pH-metry has less of an impact on activities of daily living but is not associated with fewer study-related symptoms compared with catheter-based pH-metry. The prevalence of specific study-related symptoms does differ between the 2 groups and noncardiac chest pain seems to be the primary risk factor for more severe study-related symptoms and reduced tolerance for wireless pH-metry. This information may be useful in helping to decide which patients should undergo the wireless pH-metry or receive additional counseling on procedural expectations.
