Effect of stress ulcer prophylaxis with proton pump inhibitors vs histamine-2 receptor blockers on in-hospital mortality among ICU patients receiving invasive mechanical ventilation: The PEPTIC randomized clinical trial. no proton-pump inhibitors, 40% (= 2,648) received a proton-pump inhibitor and no histamine-2 receptor antagonists, and 46% (= 3,076) had delirium. The histamine-2 receptor antagonist group had a greater association with delirium than the proton-pump inhibitor group compared with controls receiving neither medication, after controlling for mechanical ventilation and age (risk ratio, 1.36; 1.25C1.47; < 0.001) and (risk ratio, 1.15; 1.07C1.24; < 0.001, respectively). CONCLUSIONS: Histamine-2 receptor antagonists are more strongly associated with increased delirium than proton-pump inhibitors. Prospective studies are necessary to further elucidate this association and to determine if replacement of histamine-2 receptor antagonists with proton-pump inhibitors in ICUs decreases the burden of delirium in critically ill patients. values less than 0.01 were considered statistically significant. RESULTS Cohort Characteristics Between January 2015 and December 2019, 8,075 adults were admitted to the UNC-CH MICU. Of these patients, 6,645 were included in the cohort after removal of the 1,430 patients prescribed both H2RAs and PPIs in the same hospital encounter. In the remaining cohort, 45% (= 3,022) were 65 or older, 29% (= 1,899) received mechanical ventilation, and 22% (= 1,487) BTZ043 died during their MICU encounter. Of the 6,645 patients, 31% (= 2,057) received an H2RA and no PPIs, 40% (= 2,648) received a PPI and no H2RAs, and 46% (= 3,076) had a delirium diagnosis (Table ?Table11). Over 99% of patients (= 2,048) who received H2RAs were prescribed famotidine. Of those who received a PPI, 70% (= 1,839) were prescribed pantoprazole and 20% (= 517) were prescribed omeprazole. The remainder were prescribed esomeprazole (1%, = 14) and other PPIs. TABLE 1. Cohort Characteristics = 6,645, (%)= 1,937, (%)= 2,057, (%)= 2,648, (%)= 0.008). Mechanical ventilation was significantly associated with increased delirium compared with nonmechanically ventilated patients (RR, 1.69; 1.61C1.78; < 0.001). The risk of delirium was significantly higher in the H2RA group and the PPI group than controls (RR, 1.61; 1.50C1.73; < 0.001) and (RR, 1.27; 1.18C1.37; < 0.001, respectively). Risk of delirium was significantly higher in the H2RA group than that in the PPI group (RR, 1.27; 1.20C1.34; < 0.001). Association of Group Characteristics and H2RA and PPI Use With Delirium in Adjusted Analysis We built two multivariate models to assess the association of medication administration (either H2RA or PPI), age, and ventilation status with delirium. Within the H2RA model in the adjusted analysis, H2RA use, older age, and mechanical ventilation were significantly associated with delirium development (RR, 1.35; 1.25C1.47; < 0.001), (RR, 1.19; 1.11C1.26; < 0.001), and (RR, 1.44; 1.33C1.55; < 0.001, respectively) (Table ?Table22).

Over 99% of patients (= 2,048) who received H2RAs were prescribed famotidine. Of those who received a PPI, 70% (= 1,839) were prescribed pantoprazole and 20% (= 517) were prescribed omeprazole. The remainder were prescribed esomeprazole (1%, = 14) and other PPIs. TABLE 1. Cohort Characteristics = 6,645, (%)= 1,937, (%)= 2,057, (%)= 2,648, (%)= 0.008). Mechanical ventilation was significantly associated with increased delirium compared with nonmechanically ventilated patients (RR, 1.69; 1.61C1.78; < 0.001). The risk of delirium was significantly higher in the H2RA group and the PPI group than controls (RR, 1.61; 1.50C1.73; < 0.001) and (RR, 1.27; 1.18C1.37; < 0.001, respectively). Risk of delirium was significantly higher in the H2RA group than that in the PPI group (RR, 1.27; 1.20C1.34; < 0.001). Association of Group Characteristics and H2RA and PPI Use With Delirium in Adjusted Analysis We built two multivariate models to assess the association of medication administration (either H2RA or PPI), age, and ventilation status with delirium. Within the H2RA model in the adjusted analysis, H2RA use, older age, and mechanical ventilation were significantly associated with delirium development (RR, 1.35; 1.25C1.47; < 0.001), (RR, 1.19; 1.11C1.26; < 0.001), and (RR, 1.44; 1.33C1.55; < 0.001, respectively) (Table ?Table22). In the adjusted PPI models, PPI use, older age, and mechanical ventilation were significantly associated with delirium development (RR, 1.15; 1.07C1.24; < 0.001), (RR, 1.11; 1.03C1.19; = 0.003), and (RR, 1.65; 1.54C1.78; < 0.001, respectively) (Table ?Table33). Risk of delirium was significantly higher in the H2RA group than that in the PPI group (RR, 1.10; 1.04C1.17; = 0.001). TABLE 2.

When stratifying by individual PPIs given and controlling for mechanical ventilation and age, pantoprazole was significantly associated with delirium development, whereas omeprazole was not (RR, 1.15; 1.06C1.24; = 0.001) and (RR, 1.00; 0.89C1.14; = 0.93, respectively). In both of the multivariate analyses, after adjusting for older age, the risk of delirium in sufferers on either H2RAs or PPIs didn't change considerably, or by a lot more than 10% of their unadjusted worth. Thus, age had not been a substantial confounder from the association between H2RA or PPI make use of and delirium. Nevertheless, the chance of delirium in patients on either PPIs or H2RAs changed significantly after adjusting for.
