The burden of recurrence acute pancreatitis and annual event rates are underestimated because of high rates of home self-management.

BACKGROUND/

OBJECTIVES

The event-rate of recurrent acute pancreatitis (RAP) in patient populations is critical for powering research studies. We hypothesize that some patients manage RAP attacks at home, reducing event rate estimations based on counting emergency department (ED) visits and hospitalizations only. The aim of this study was to determine the rates of home self-management of recurrent acute pancreatitis compared to ED visits and hospitalizations.

METHODS

An anonymous 8-question survey was sent to 1825 individuals on an email list of individuals with a history of acute pancreatitis (AP) or chronic pancreatitis or interest in pancreatic diseases. Question were designed to identify subjects with RAP within the past 2 years and to subdivide patients based on having a chronic pain syndrome or not.

RESULTS

After an initial email request and one reminder a total of 194 subjects responded with 98 RAP subjects suitable for analysis. Annual AP events included an average of 1.44 hospitalizations, 1.37 ED visits, 2.46 disrupted work/school/social engagements, and 3.95 pancreatitis-like pain attacks per year. Patients with RAP average 6.8 RAP events per year with 58.4 % managed at home.

CONCLUSIONS

The burden of disease in patients with RAP is significantly underestimated, especially for patients with chronic pain. Future studies should include measures to capture RAP events managed at home and utilize methods of documenting RAP events.
