Introduction
Economic evaluations in healthcare can guide practice and inform policy. The objective of this paper is to present the protocol for a health economic evaluation comparing the cost-effectiveness of prophylactic treatment using pantoprazole 40 mg IV daily compared to no pantoprazole to prevent upper gastrointestinal (GI) bleed among invasively ventilated patients.
Methods and analysis
This is an economic evaluation conducted alongside the R e- E valuating the I nhibition of S tress E rosions trial. The primary outcome is the incremental cost per clinically-important upper GI bleed prevented. Secondary outcomes include the incremental cost of a patient-important upper GI bleed prevented. We will explore the incremental cost per secondary trial outcome (e.g., ventilator-associated pneumonia, Clostridioides difficile infection, and patient-important GI bleeding); and incremental cost per life gained. The analysis will be conducted from a Canadian public healthcare payer’s perspective over a time horizon of ICU admission to hospital discharge or death. The study protocol was developed following good practice guidelines of Canada’s Drug Agency (CDA) and the Professional Society for Health Economics and Outcomes Research (ISPOR).
Ethics and dissemination
The trial was approved by the Hamilton Integrated Research Ethics Board and at each participating institution; this economic evaluation is currently under review for ethics approval. Given widespread daily use of proton pump inhibitors for critically ill patients, the results of this economic evaluation will be of high relevance to patients, family members, physicians, pharmacists, policymakers and guideline developers. Integrated knowledge translation will involve periodic progress reports to collaborators. End-of-study knowledge translation will include rounds, videoconferences, abstracts and slide-decks for ICU quality councils and healthcare organizations, and open-access publications. Patient and Family Partners will co-create lay language summaries for traditional and social media to help inform all stakeholders.
