OBJECTIVES:
Prescription of prophylactic antibiotics in acute pancreatitis (AP) is controversial. We aimed to identify the patients' characteristics that may prompt clinicians to prescribe prophylactic antibiotics in AP.
METHODS:
This single-center retrospective cohort study included 299 consecutive patients with AP from a Portuguese hospital in 2009 to 2010. Logistic regression was used to study the association of patients' characteristics with prescription of prophylactic antibiotics in AP.
RESULTS:
Persistent organ failure developed in 7% of patients (9/136). The median C-reactive protein at 48 hours after hospital admission was 154 mg/L (interquartile range, 55-271 mg/L). Bedside Index for Severity in AP score greater than or equal to 3 occurred in 14% of patients (42/299). Pancreatic necrosis was diagnosed in 21% of the patients (35/169). Computerized Tomography Severity Index score greater than 3 occurred in 23% of patients (38/169). In-hospital mortality rate was 4% (10/299). Prophylactic antibiotics were prescribed to 14% of patients (42/299). After adjusting for persistent organ failure and Computerized Tomography Severity Index score greater than 3, C-reactive protein at 48 hours after hospital admission greater than or equal to 150 mg/L was significantly associated with higher likelihood of receiving prophylactic antibiotics (odds ratio, 12.2). Prophylactic antibiotics did not improve in-hospital mortality rate (P = 0.637).
CONCLUSIONS:
C-reactive protein was the most influential in prescribing prophylactic antibiotics in AP. Clinicians may need better tools to support the decision to prescribe prophylactic antibiotics in AP.
