Objective:
The aim of this meta-analysis was to estimate the incidence of pressure ulcers (PUs) in the emergency department (ED).
Methods:
The authors searched PubMed, Web of Science, and CINAHL databases for all time leading up to February 2016. The incidence of PUs in the ED were collected, and the pooled incidence with 95% confidence interval (CI) was calculated by meta-analysis.
Results:
Six studies with 8 cohorts were included in this study. The incidence of PUs in the ED ranged from 0.38% to 19.1%. The pooled incidence was 6.310% (95% CI 4.658%-7.962%; Z = 7.49, P = 0.000) by the random-effects model (I2 = 98.2%, P = 0.000). Funnel plot, Begg's test (z = 0.37, P = 0.711) and Egger's test (t = 2.73, P = 0.034) suggested there was significant publication bias. Sensitivity analysis that included prospective studies showed the pooled incidence was 11.992% (95% CI 5.569%-18.415%; Z = 3.66, P = 0.000) by the random-effects model (I2 = 93.9%, P = 0.000).
Conclusion:
Even for a short stay in the ED, developing a PU is a common complication. The figures of this meta-analysis may be useful in the estimation of the PU burden in the ED.

Few clinical manifestations differentiate gastric ulcers from duodenal ulcers. Distinctions in the location, timing, and pain relief are crucial for healthcare providers in differentiating between gastric and duodenal ulcers during clinical assessments.
01:30Peptic Ulcer Disease I: Introduction
An acute ulcer, marked by superficial erosion and minimal inflammation, swiftly resolves upon identifying and addressing the underlying cause. In contrast, a chronic ulcer persists, potentially eroding through the muscular wall and forming fibrous tissue.

Damaging agents such as Helicobacter pylori, gastric acid, pepsin, and nonsteroidal anti-inflammatory drugs (NSAIDs) can weaken the mucosal defense, allowing hydrogen ions to infiltrate back and harm epithelial cells.
