One fifth of hospitalizations for peptic ulcer-related bleeding are potentially preventable

A Machine Learning Approach to Identify Predictors of Potentially Inappropriate Non-Steroidal Anti-Inflammatory Drugs (NSAIDs) Use in Older Adults with Osteoarthritis

Evidence from some studies suggest that osteoarthritis (OA) patients are often prescribed non-steroidal anti-inflammatory drugs (NSAIDs) that are not in accordance with their cardiovascular (CV) or gastrointestinal (GI) risk profiles. However, no such study has been carried out in the United States. Therefore, we sought to examine the prevalence and predictors of potentially inappropriate NSAIDs use in older adults (age > 65) with OA using machine learning with real-world data from Optum De-identified Clinformatics^® Data Mart. We identified a retrospective cohort of eligible individuals using data from 2015 (baseline) and 2016 (follow-up). Potentially inappropriate NSAIDs use was identified using the type (COX-2 selective vs. non-selective) and length of NSAIDs use and an individual's CV and GI risk. Predictors of potentially inappropriate NSAIDs use were identified using eXtreme Gradient Boosting. Our study cohort comprised of 44,990 individuals (mean age 75.9 years). We found that 12.8% individuals had potentially inappropriate NSAIDs use, but the rate was disproportionately higher (44.5%) in individuals at low CV/high GI risk. Longer duration of NSAIDs use during baseline (AOR 1.02; 95% CI:1.02-1.02 for both non-selective and selective NSAIDs) was associated with a higher risk of potentially inappropriate NSAIDs use. Additionally, individuals with low CV/high GI (AOR 1.34; 95% CI:1.20-1.50) and high CV/low GI risk (AOR 1.61; 95% CI:1.34-1.93) were also more likely to have potentially inappropriate NSAIDs use. Heightened surveillance of older adults with OA requiring NSAIDs is warranted.

Endoscopic treatment modalities and outcomes in nonvariceal upper gastrointestinal bleeding

BACKGROUND

In nonvariceal upper gastrointestinal bleeding (NVUGIB), the optimal volume of adrenaline, the optimal number of hemoclips, and the application of thermal coagulation in determining patient outcomes have not been well studied.

AIM

To demonstrate a dose-response relationship between the commonly used endoscopic modalities for the treatment of non-variceal upper gastrointestinal bleeding and various clinical outcomes.

METHODS

Patients presenting with NVUGIB were retrospectively identified and analyzed. These patients were stratified as follows: (1) > 10 mL of adrenaline injected vs ≤ 10 mL; (2) > 1 hemoclip placed vs ≤ 1 hemoclip; (3) Heater probe used or not; and (4) > 2 treatment modalities used vs ≤ 2. The primary outcomes were rebleeding and the need for repeat endoscopy. The secondary outcomes were the need for surgery, required transfusions, length of hospital stay, death during the same admission period and 30 d mortality. Patients with NVUGIB who required endoscopic therapy were included. Those who did not require endoscopic therapy or were initially treated with surgery or embolization were excluded.

RESULTS

In all, 501 patients with NVUGIB were treated. One hundred sixty-one (32.1%) patients needed endoscopic therapy. The injection of < 10 mL of adrenaline was associated with less rebleeding (P < 0.0001), the need for repeat endoscopy (P = 0.001) and a decreased length of hospital stay (P = 0.026). The use of > 2 treatment modalities were associated with increased rebleeding (P = 0.009) and the need for repeat endoscopy (P = 0.048). The placement of > 1 hemoclip was associated with a decreased length of hospital stay (P = 0.044). The rates of surgery and death were low, and there were no other significant differences between the patient groups.

CONCLUSION

The more restrictive use of adrenaline and number of endoscopic modalities to treat NVUGIB with the more liberal use of hemoclips was associated with better patient outcomes.

Clinical Outcomes of Patients with Non-ulcer and Non-variceal Upper Gastrointestinal Bleeding: A Prospective Multicenter Study of Risk Prediction Using a Scoring System

BACKGROUND AND AIMS

Compared with ulcer bleeding (UB) in non-variceal upper gastrointestinal bleeding (NVUGIB), non-ulcer bleeding (NUB) is often considered to have a low risk of poor outcomes and is treated less intensively without any risk stratification. We conducted this study to assess the predictability of scoring systems for NUB and compare the outcomes of NUB and UB.

METHODS

A total of 1831 UGIB patients were registered in the database during the period from February 2011 to December 2013. Among them, 1424 patients with NVUGIB were divided into two groups: Group UB (1101 patients with peptic ulcer bleeding) and Group NUB (323 patients with non-peptic ulcer-related bleeding).

RESULTS

The most common cause of bleeding in Group NUB was Mallory-Weiss tears (51.1%), followed by Dieulafoy lesions (18.9%). A receiver operating characteristic (ROC) analysis revealed that the pre-Rockall score [area under the ROC (AUROC) = 0.798; 95% CI 0.707-0.890] and full Rockall score (AUROC = 0.794; 95% CI 0.693-0.895) were relatively good at predicting overall mortality in NUB. Glasgow-Blatchford score (AUROC = 0.783; 95% CI 0.730-0.836) was the most closely correlated with the need for clinical intervention in NUB. Those who had Glasgow-Blatchford score of 0 did not require any interventions, including blood transfusions. There were no statistical differences in overall mortality (p = 0.387), bleeding-related mortality (p = 0.447), or the incidence of re-bleeding (p = 0.117) between the two groups.

CONCLUSIONS

Scoring systems are useful to predict mortality and the need for clinical intervention in patients with NUB.

Prevalence of upper gastrointestinal endoscopic findings in the community: A systematic review of studies in unselected samples of subjects

BACKGROUND AND AIM

Upper gastrointestinal endoscopic findings, such as esophagitis, Barrett's esophagus, peptic ulcer, and malignancy, represent a public health problem. This systematic review aimed to evaluate the prevalence of upper gastrointestinal endoscopic findings in the community.

METHODS

A systematic search was conducted in PUBMED and EMBASE to May 2015. Studies were eligible if they reported the prevalence of upper gastrointestinal endoscopic findings in unselected samples of the community.

RESULTS

Twelve articles were eligible, nine reported data from three endoscopic surveys (n = 3063 subjects), and three from national screening programs (n = 84 153). The overall prevalence of upper gastrointestinal endoscopic findings in the community was 30% in the Kalixanda study (Sweden), 24.9% in the Loiano-Monghidoro study (Italy), and 68.9% in the Systematic Investigation of Gastrointestinal Diseases study (China). The pooled prevalence of esophagitis, endoscopically suspected esophageal metaplasia (ESEM), peptic ulcer, and gastric cancer in all studies was 11.2, 5.1, 6.8, and 0.33%, respectively. The most frequent finding was esophagitis in Europe, with a prevalence of 15.5% in Sweden and 11.8% in Italy, and peptic ulcer in China (17.1%), both in asymptomatic and symptomatic individuals. The prevalence of Helicobacter pylori was positively associated with the prevalence of peptic ulcer (r = 0.91) but negatively associated with the prevalence of both esophagitis (r = -0.99) and ESEM (r = -0.95).

CONCLUSIONS

Upper gastrointestinal endoscopic findings are present in at least a quarter of subjects in the community with different patterns in Western and Eastern countries, both in asymptomatic and symptomatic subjects. H. pylori prevalence negatively impacts on the prevalence of reflux-related esophageal findings.
