title: Predictive factors for and incidence of hospital readmissions of patients with acute and chronic pancreatitis.
abstract: OBJECTIVE
  Acute and chronic pancreatitis are common gastroenterological disorders that have a fairly unpredictable long-term course often associated with unplanned hospital readmissions. Little is known about the factors that increase or decrease the risk for a hospital readmission. The aim of this study was to identify positive and negative predictive factors for hospital readmissions of patients with acute and chronic pancreatitis after in-hospital treatment.
  
  
  METHODS
  In a retrospective analysis data from the hospital information and reimbursement data system (HIS) were evaluated for 606 hospital stays for either acute or chronic pancreatitis between 2006 and 2011. Additional clinical data were obtained from a questionnaire covering quality of life and socio-economic status. A total of 973 patient variables were assessed by bivariate and multivariate analysis.
  
  
  RESULTS
  Between 2006 and 2011, 373 patients were admitted for acute or chronic pancreatitis; 107 patients of them were readmitted and 266 had only one hospitalization. Predictors for readmission were concomitant liver disease, presence of a pseudocyst or a suspected tumor of the pancreas as well as alcohol, tobacco or substance abuse or coexisting mental disorders. Patients who had undergone a CT-scan were more susceptible to readmission. Lower readmissions rates were found in patients with diabetes mellitus or gallstone disease as co-morbidity.
  
  
  CONCLUSIONS
  While factors like age and severity of the initial disease cannot be influenced to reduce the readmission rate for pancreatitis, variables like alcohol, tobacco and drug abuse can be addressed in outpatient programs to reduce disease recurrence and readmission rates for pancreatitis.
