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.

Efficacy and safety of stress ulcer prophylaxis in septic patients: a retrospective cohort study based on large database / 中华危重病急救医学

Objective:To evaluate the effects and safety of stress ulcer prophylaxis (SUP) versus no prophylaxis in adult septic patients at risk of gastrointestinal bleeding (GIB).Methods:A retrospective cohort study was conducted, the data was extracted from Electronic Intensive Care Unit-Collaborative Research Database (eICU-CRD). All patients who received proton pump inhibitor (PPI) or H 2 receptor antagonist (H 2RA) or combined/sequential use for SUP within the first 48 hours of intensive care unit (ICU) admission were enrolled in the SUP group, those who did not received any SUP were enrolled in the non-SUP group. The differences of in-hospital mortality, length of ICU stay (LOS), the incidence of GIB and secondary infection complications between the two groups were compared. Propensity score matching (PSM) was conducted to balance the distributions of study variables between the two groups. Further subgroup analysis was performed according to whether SUP was used for more than 3 days. Multivariate Logistic regression analysis was conducted to analyze the factors influencing the outcome of GIB and secondary pneumonia. Results:A total of 11 413 patients were included in the final analysis, with 9 799 patients in SUP group and 1 614 in non-SUP group. A 1∶1 PSM created 1 600 patients in each cohort. ① Baseline characteristics: compared with SUP group, patients in non-SUP group were older [years old: 69.0 (56.0, 80.0) vs. 67.0 (56.0, 78.0)], acute physiology and chronic health evaluation Ⅳ (APACHEⅣ) score and sequential organ failure assessment (SOFA) score were significantly lower [APACHEⅣ score: 65 (50, 73) vs. 72 (58, 87), SOFA score: 5 (4, 7) vs. 7 (5, 9)], higher rates of underlying diseases such as hypertension and diabetes [hypertension: 15.6% (252/1 614) vs. 12.2% (1 196/9 779), diabetes: 4.5% (72/1 614) vs. 3.3% (325/9 779), both P < 0.05], indicating that patients in the SUP group were more severe. ② Comparison of clinical outcome: before PSM, SUP group had significantly higher in-hospital mortality [17.2% (1 688/9 799) vs. 10.9% (176/1 614)], longer LOS [days: 4.4 (2.9, 7.7) vs. 3.1 (2.5, 4.3)], and higher incidence of secondary pneumonia than non-SUP group [11.3% (1 112/9 799) vs. 6.8% (110/1 614)], with significant differences (all P < 0.05). There was no significant difference in the incidence of GIB and Clostridium difficile infection (CDI) between the two groups. After PSM, no significant differences were observed between the two groups with regard to in-hospital mortality, incidence of GIB and CDI. However, the SUP group had longer LOS [days: 3.9 (2.8, 6.6) vs. 3.1 (2.5, 4.3)], and higher incidence of secondary pneumonia [10.9% (174/1 600) vs. 6.8% (108/1 600)] compared with non-SUP group, the differences were statistically significant (all P < 0.05). Subgroup analysis showed that compared with SUP < 3 days group, patients in SUP ≥ 3 days group had higher disease severity score [APACHEⅣ score: 66 (51, 79) vs. 62 (48, 72), SOFA score: 6 (4, 8) vs. 5 (4, 7), both P < 0.05], in addition, patients in SUP≥3 days group had higher in-hospital mortality, incidence of GIB and secondary pneumonia (16.4% vs. 10.7%, 6.1% vs. 1.8%, 19.0% vs. 8.6%, respectively), and longer ICU LOS [days: 6.6 (4.1, 11.8) vs. 3.5 (2.6, 5.3), all P < 0.05]. ③ Multivariate Logistic regression analysis showed that SUP≥3 days group was associated with more GIB than that of non-SUP group [odds ratio ( OR) = 1.84, 95% confidence interval (95% CI) was 1.07-3.08, P = 0.030], and the incidence of GIB was less in SUP < 3 days group than that of non-SUP group ( OR = 0.57, 95% CI was 0.34-0.94, P = 0.020). When compared with non-SUP group, the risk of secondary pneumonia was increased both in SUP≥ 3 days group and SUP < 3 days group ( OR values were 2.95 and 1.34, 95% CI were 2.10-4.13 and 1.01-1.77, P values were < 0.001 and 0.040, respectively). Conclusion:Among critically ill adult patients with sepsis at risk for GIB, SUP showed no effect on reducing in-hospital mortality, the rate of GIB and CDI, but was associated with increased risk of secondary pneumonia and prolonged LOS.

Comparison of Histamine 2 Receptor Antagonists and Proton Pump Inhibitors on Infectious Complications in Critically Ill Patients

BACKGROUND: The use of acid suppressive agents became a standard therapy in an intensive care unit (ICU) to prevent stress related gastrointestinal mucosal damage. However, the risk of infectious diseases has been concerned. OBJECTIVE: The study was to determine the differences between histamine 2 receptor antagonists (H2RA) and proton pump inhibitors (PPI) in incidence of nosocomial pneumonia and pseudomembranous colitis (PMC) by Clostridium difficile with patients in ICU. METHODS: This is a retrospective comparative study including patients admitted to the ICU who were at least 18 years of age and stayed for more than 48hrs from August 1, 2014 to January 31, 2015. The propensity score analysis and propensity matched multivariable logistic regression were used in analyzing data to control for confounders. RESULTS: A total of 155 patients were assessed. H2RA were prescribed in 110 (53.9%) and PPI were in 45 (22.1%). Nosocomial pneumonia developed in 37 (23.9%); 25 (22.7%) were on H2RA and 12 (26.7%) were on PPI. The unadjusted incidence of nosocomial pneumonia was slightly higher in the patients with PPI (odds ratio (OR) 1.24; 95% confidence interval (CI): 0.54-2.71) compared to them with H2A. After adjusting with propensity score, the adjusted OR with PPI was 1.35 (95% CI: 0.44-4.11). The propensity score matched analyses showed similar results. CONCLUSION: The uses of PPI and H2RA as a stress ulcer prophylaxis agent showed similarity in the incidence of nosocomial pneumonia and PMC.

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.
