Rational use of acid suppressant for stress ulcer in PICU / 中国小儿急救医学

Stress-related digestive tract mucosal disease is a common complication in pediatric intensive care unit(PICU). It may progress to stress ulcer and severe ulcer bleeding, which may lead to death.Currently, stress ulcer prophylaxis is recommended for critically ill children with high risk factors for stress ulcer, and the most commonly used acid suppression drugs are proton pump inhibitor and histamine-2 receptor antagonist.However, excessive prophylactic acid suppression is common and can increase the risk of hospital-acquired pneumonia and clostridium difficile infection in PICU.This review aimed to analyze the advantages and disadvantages of preventive acid suppressant therapy and promote the rational use of acid suppressant in PICU.

Risk of Clostridium difficile Infection with the Use of a Proton Pump Inhibitor for Stress Ulcer Prophylaxis in Critically Ill Patients

BACKGROUND/AIMS: Proton pump inhibitors (PPIs) and histamine-2 receptor antagonists (H2RAs) are commonly prescribed for stress ulcer prophylaxis (SUP) in critically ill patients. Several studies have suggested that the use of PPIs is a potential risk factor for Clostridium difficile infection (CDI). We compared the incidences of CDI in the PPI group and H2RA group for SUP in critically ill patients. METHODS: From August 2005 to July 2012, the incidences of CDI were retrospectively analyzed in patients who were admitted directly to intensive care units and stayed for more than 3 days. SUP-related CDI was defined as a CDI diagnosed during the SUP period. Patient clinical data were analyzed to identify potential risk factors for SUP-related CDI. RESULTS: Of the 1,005 patients enrolled (444 patients received PPI and 561 received H2RA), 38 (3.8%) were diagnosed with SUP-related CDI. The incidence of SUP-related CDI was considerably higher in patients who received PPI than in those who received H2RA (6.7% vs 1.8%). PPI use for SUP (odds ratio [OR], 3.3; confidence interval [CI], 1.5 to 7.1; p=0.003) and diabetes mellitus (OR, 2.3; CI, 1.2 to 4.7; p=0.019) were independent risk factors for SUP-related CDI. CONCLUSIONS: PPI therapy is associated with a higher risk of SUP-related CDI than H2RA therapy in critically ill patients.

Analysis of Healthcare Personnel's Clinical Beliefs and Knowledge behind Overutilization of Stress Ulcer Prophylaxis in Hospitalized Patients

BACKGROUND: The over-prescription of acid-suppressive therapy for the provision of stress ulcer prophylaxis (SUP) in hospitalized patients has been identified in a proceeding study. OBJECTIVE: This study was conducted to evaluate clinicians' beliefs, knowledge and other factors that influence the over-prescribing of SUP in low-risk, non-intensive care unit (non-ICU) patients. METHOD: A cross-sectional survey consisting of multiple-choice queries and close-ended questions was distributed to healthcare personnel at a major teaching hospital in Korea. RESULTS: More than half of total respondents reported that they would continue SUP following patients discharge from the ICU (77.8%, 43.5%, and 39.7% in the physician, pharmacist, and nurse groups, respectively). Over 55% of physicians would also initiate non-ICU patients on SUP upon hospital admission, and 42.6% of physicians would even continue prophylaxis post hospital discharge. The mean knowledge score regarding SUP indications and side effects was higher in pharmacists compared to physicians and nurses (12.44, 7.40, and 7.28, respectively; p<0.001). High-prescribing behavior was associated with a prescriber's belief that SUP is effective for preventing bleeding (odds ratio 7.40; 95% confidence interval 1.57 to 31.94; p=0.012). Low knowledge score and computerized order set also showed statistically significant association with the overutilization of SUP.
