Studies predicting the incidence rate for individuals with a given set of characteristics are lacking. The aim of this study was to develop a risk model to predict the incidence rate of upper gastrointestinal bleeding (UGIB) in users of aspirin\/NSAID based on presence of well\u2010defined risk factors for the individual patient.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>The model was developed from data from a case\u2010control study, sampled from a well\u2010defined source population, residents of the Funen County 1995\u20102006. All cases and controls were characterized in terms of factors known to affect the risk of UGIB. By using census data, we rescaled the control group, so their composition accurately reflected age and sex distribution of the source population. Only persons using NSAIDs or\/and aspirin and no PPI were included in the analysis. As reference group, we chose 80\u2010 to 89\u2010year\u2010old women with no ulcer history, using NSAID, but neither aspirin, other platelet inhibitors, vitamin K antagonists, selective serotonin reuptake inhibitors nor corticosteroids.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>We identified 1388 cases among non\u2010users of PPIs. We found a modelled baseline incidence rate of 10.7 per 1000 person\u2010years for the reference group. The strongest associations were found for ADP inhibitors (OR 5.80), followed by anticoagulants treatment (OR 2.62) and prior ulcer (OR 2.68). The model performed well in terms of calibration and discriminatory power.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>This study is the first to describe a model, which estimates the incidence rate of UGIB for patients using aspirin\/NSAID, based on the specific combination of risk factors.
