The PAN-PROMISE study (PAtieNt-rePoRted OutcoMe scale in acute pancreatItis-an international proSpEctive cohort study) aims to measure an outcome variable in acute pancreatitis (AP) based in the patient´s experience. PAN-PROMISE is a cohort study involving patients with AP. The patient´s symptom perception will be compared with the opinion of the clinicians and with clinical outcomes.

Currently, the most important outcome variables in Acute Pancreatitis (AP) are persistent organ failure (POF) and mortality, according to the physician point of view. These variables occur infrequently (\<10 and \<5% respectively) (Sternby et all, see References), therefore, studies designed to assess the effectiveness of new treatments for AP to decrease POF or mortality require a very large sample of patients, which is unfeasible. Currently, clinical trials addressing the management of AP do not take into account Patient Reported Outcome Measures. PROMS (Patient Reported Outcome Measures) have been defined as any report of the status of a patient's health condition that comes directly from the patient, without interpretation of the patient's response by a clinician or anyone else (first link in References). PROMS are gaining importance as a tool to design outcome variables. This kind of measurement has been recently included in the quality assesment approaches (Crossing the Quality Chasm: A New Health System for the 21st Century, see References), being PROMS a useful tool to improve the triple aim framework of better quality, appropriate utilization, and enhanced patient experience (second link in References). The aim of PAN-PROMISE is to incorporate an outcome variable in AP based in the patient´s experience. For this purpose the investigators involved in this project have developed a new instrument based on symptoms found to be important for the patient. This new instrument is intended to be a simple quantitative variable, relevant for the patient, that can be useful to test new treatments for AP without the need for a very large sample size, fulfilling the requirements of the triple aim framework by incorporating an outcome measurement defined by the patient. Hypothesis: * PROMS must be incorporated to patient care and research in AP to improve the triple aim framework of better quality, appropriate utilization, and enhanced patient experience * A PROMS scale is a useful outcome variable to investigate new treatments in AP * The different severity categories of the revision of the Atlanta Classification (RAC) have different scores on the PROMS scale in acute pancreatitis: severe greater than moderate and mild, moderate greater than mild. * Increasing scores on the PROMS scale are associated to increased morbidity Aims: * Main aim 1: to measure patient´s symptoms during an episode of AP and to correlate the intensity of these symptoms to clinical outcomes * Main aim 2: to design and validate a PROMS scale in AP intended to be an suitable outcome variable in future trials addressing the management of AP Methods Part 1: development of the PAN-PROMISE instrument The PAN-PROMISE research team developed a qualitative study in which three nominal groups were conducted, two with patients who had suffered an acute pancreatitis (AP) in hospitals in Alicante (Universitarian General Hospital)), and Valencia (Clinic Hospital), Spain and another with clinicians from the Alicante region with experience in treating patients with AP. Participants were asked about the symptoms that cause the most discomfort and concern to patients at three specific times: before receiving treatment for AP, during hospital admission and after discharge. The perspectives of patients and professionals were compared. From the information gathered in the nominal groups, a first version of a PROMS questionnaire was elaborated and shared with an international group of gastroenterologists, experienced in the management of pancreatitis, from 4 countries (Germany, Spain, USA, India and Turkey) through an online application to determine to what extent these experiences were shared in frequency and intensity by patients in these different countries. With all this information, a PROMS instrument was generated. Part 2: measurement of patient´s symptoms in an international cohort study 2.1 Design. The PAN-PROMISE instrument is being measured in patients participating in a multicenter international prospective cohort study. Consecutive adult patients with AP are eligible after signed informed consent. 2.2 Center recruitment The PAN-PROMISE study has been endorsed by the Spanish Association of Pancreatology (AESPANC), the Spanish Association of Gastroenterology (AEG) and the International Association of Pancreatology (IAP); these associations shared the project with their members and through their social networks, calling for researchers and centers to join this initiative. PAN-PROMISE has also a webpage www.promisepancreatitis.com to promote center recruitment. 2.3 Patient registry PAN-PROMISE measurement will rely on a patient registry hosted in the Spanish Association of Gastroenterology (AEG) REDCap node. AEG offered this REDCap web-based online patient registry tool at no cost. Claudia Sánchez-Marin, a gastroenterologist, is on charge of quality control (data validation, data checks, contact with researchers to solve issues). The REDCap online registry was designed with logical rules to ensure good quality data entry, including mandatory fields to enter, logical ranges for quantitative variables, alarms if logical rules are not coherent (for example to have persistent organ failure but to classify the episode as mild or moderate), expanding fields only available in the presence of certain circumstances (for example, detailed organ failure description is only available if the patient had organ failure).
