Internet-delivered CBT for Patients With NCCP

Non-cardiac chest pain (NCCP) is common and has substantial impact on patients' psychological wellbeing, quality of life and healthcare use. Although cardiac diagnosis is 'ruled out', many patients think they have an undetected cardiac disease (i.e. they suffer cardiac anxiety) as no other explanation is offered. They therefore avoid activities that they believe might be harmful to their heart, leading to greater ill-health, and increased healthcare use and societal costs. Targeting cardiac anxiety with psychological interventions might break this vicious circle and improve patient outcomes. Patients need to evaluate the way they perceive and handle their chest pain, which can be done with cognitive behavioral therapy (CBT). The aim of this study is therefore to evaluate the short- and long-term effects of an Internet-delivered CBT (I-CBT) program on psychological distress and other patient-reported outcomes in patients with NCCP. A second aim is to explore factors related to implementation of I-CBT in clinical care. The study has a randomized controlled design comparing I-CBT with Internet-delivered information program. Quantitative methods will be used to evaluate the effectiveness of the I-CBT program. Implementation issues will be evaluated from the perspectives of patients, healthcare professionals and policymakers using qualitative methods.
