The goal of this observational study is to compare the prognostic value of different nutritional screening tools to predict the course of acute pancreatitis.
The main questions it aims to answer are:
Participants will answer questions regarding their nutritional status and undergo basic anthropometric assessments (e.g. measurement of waist circumference) to evaluate their risk of malnutrition.
Malnutrition seems to be related to an adverse outcome of acute pancreatitis. However, it is still unclear which of the various available nutritional screening tools is suited best to predict the clinical outcome in hospitalized patients with acute pancreatitis.
Therefore, in this study we compare the predictive performance of 6 different nutritional screening tools that are commonly applied in clinical practice regarding their respective associations with severity of acute pancreatitis, length of hospital stay, mortality and need for rehospitalization.
To determine patients' nutritional status, subjects will be inquired about their recent food intake as well as body weight and undergo basic anthropometric assessments according to the different screening tools.
Six months after the initial diagnosis patients will be contacted via mail to report on need for rehospitalization due to acute pancreatitis during this time period.
