Evaluation of Chinese updated guideline for acute pancreatitis on management of moderately severe and severe acute pancreatitis.

Background: /Objectives: The management of acute pancreatitis (AP) in China has undergone major changes since the launch of the updated guideline in 2013. This study aimed to evaluate the impact of this guideline on clinical practice and patient outcome.
Methods: Moderately severe and severe adult AP patients, who were admitted to Peking Union Medical College Hospital from January 1, 2001 to December 31, 2016, were retrospectively included in the study. All enrolled patients were divided into two groups based on the publication date of the updated guideline, as the pre-guideline (Pre) group and post-guideline (Post) group. In-hospital case-fatality rates were compared between two groups after adjusting baseline features, including gender, age, etiology and disease severity. In addition, the associations between specific therapeutic approaches recommended in the updated guideline and in-hospital case-fatality rates were explored.
Results: A total of 475 patients were enrolled in this study, including 273 (57%) in the Pre group and 202 (43%) in the Post group. The adjusted in-hospital case-fatality rate significantly decreased in the Post group (14.3% vs. 5.9%, OR 0.39, 95%CI 0.19-0.82). In the post-hoc analysis, the use of enteral nutrition was a protective factor against in-hospital death (OR: 0.08, 95%CI: 0.03-0.18), while open surgery showed an opposite effect (OR: 3.81, 95%CI: 1.06-13.74). Prophylactic antibiotics was not significantly associated with in-hospital death (OR: 1.00, 95%CI: 0.39-2.60).
Conclusions: There was a prominent transition in the management of moderately severe and severe AP after the release of the guideline in China in 2013, which made the prognosis better.
