Generation of Risk Score for Serious Non-Steroidal Anti-Inflammatory Drug (NSAID) Induced Cardiovascular Events (NAÏVE) among Active-Duty Service Members and Veterans

Abstract

AbstractImportanceCardiovascular disease (CVD) is a major global health concern, responsible for a significant proportion of deaths annually. Despite the widespread use of nonsteroidal anti-inflammatory drugs (NSAIDs) in managing various conditions, their association with cardiovascular events poses a challenge, and existing guidelines lack a reliable risk prediction tool. This study addresses the critical need for an evidence-based instrument to assess the likelihood of NSAID-induced cardiovascular events, that provides clinicians with valuable decision support to improve safety in their use for pain management, especially in patients vulnerable to cardiovascular events.ObjectiveTo develop a practical risk scoring tool, NSAID Induced Cardiovascular Events (NAÏVE), for estimating the risk of serious cardiovascular events associated with NSAID use.DesignRetrospective nested case-control studySettingThe study leveraged data from the DAVINCI database, integrating electronic health records, administrative data, and clinical data from both the Veterans Health Administration (VHA) and the Department of Defense (DoD).ParticipantsThe study cohort consisted of individuals with at least one NSAID pharmacy claim, with cases defined as those experiencing non-fatal myocardial infarction, non-fatal stroke, or new heart failure.InterventionsDevelopment of the NAÏVE risk scoring tool involved a comprehensive analysis of demographic, clinical, and prescription-related variables, including NSAID exposure, comorbidities, and medication history.Main Outcomes/MeasuresThe primary outcome was the first occurrence of a cardiovascular event.ResultsThe study cohort comprised 231,967 cases and 2,319,670 controls, identified from individuals with at least one NSAID pharmacy claim between October 1, 2016, and September 30, 2020. The risk index, NAÏVE, demonstrated strong discriminatory ability and calibration, with a C-statistic of 0.88. Variables such as age, NSAID exposure, comorbidities, and medication history were associated with increased odds of NSAID-induced cardiovascular events.Conclusions/RelevanceNAÏVE is the first evidence-based risk scoring tool providing clinicians with valuable decision support for assessing the potential risk of serious cardiovascular events associated with NSAID use. It fills a crucial gap in clinical practice, allowing for transparent discussions with patients and shared decision-making regarding NSAID prescriptions. Further validation and prospective testing are warranted for broader applicability.
