Potentially preventable complications in epilepsy admissions: The "weekend effect"

Recent patterns of vagal nerve stimulator use in the United States: Is there a racial disparity?

OBJECTIVE

Patients with refractory epilepsy are at a high risk of complications but may not receive the same level of care across racial groups. We aimed to ascertain racial inequalities and trends in the use of a vagal nerve stimulator (VNS) among adult patients with refractory epilepsy.

METHODS

A total of 24 159 adults (18 years and older) with refractory epilepsy from the National Inpatient Sample between the years 2006 and 2014 were included in this analysis. We used a multivariate logistic regression analysis to evaluate independent predictors of VNS use among patients with refractory epilepsy. Covariates included gender, age, insurance type, and household income. In addition, we evaluated for trends in VNS use over the 9-year period of data collection.

RESULTS

A total of 1.56% of patients with refractory epilepsy had used a VNS between 2006 and 2014. Overall, there was a trend of decreased use of a VNS between 2006-2008 (2.1%) and 2012-2014 (0.9%). In the adjusted multivariate logistic regression analysis, blacks (odds ratio [OR] = 0.52, 95% confidence interval [CI] = 0.35-0.77) were significantly less likely to have used a VNS relative to non-Hispanic whites. Additional factors independently associated with a decreased likelihood of VNS use were age > 65 years (OR = 0.51, 95% CI = 0.28-0.95) and years 2012-2014 (OR = 0.44, 95% CI = 0.28-0.67).

SIGNIFICANCE

There was a trend toward a decrease in the use of a VNS among adult patients with refractory epilepsy. Our results also suggest that black patients with refractory epilepsy were less likely to receive a VNS independently of other variables. Increased work toward effectively reducing racial disparities in access to quality epilepsy care is crucial.

Weekend Effect in Acute Pancreatitis-Related Hospital Admissions in the United States: An Analysis of the Nationwide Inpatient Sample

OBJECTIVE

This study aimed to assess the difference in overall outcomes between weekend admissions for acute pancreatitis (AP) and weekday admissions.

METHODS

Between 2005 and 2012, data were extracted from the Nationwide Inpatient Sample on adult patients with AP. Exclusion criteria were applied for chronic pancreatitis and other pancreatic and biliary malignancies. In-hospital mortality, length of stay, hospitalization costs, comorbidities, complications, and intervention rates were compared between the weekend and weekday admissions.

RESULTS

During the study period, there were a total of 432,303 weekday admissions and 147,435 weekend admissions for AP in the United States hospitals. Weekend AP admissions were more likely to develop alcohol withdrawal (5.9% vs 5.7%, P = 0.001) and ileus (4.1% vs 3.1%, P = 0.04). They were also more likely to develop acute respiratory distress syndrome (4.7% vs 4.4%, P < 0.001) and required more endotracheal intubation (3.9% vs 3.6%, P < 0.001). There was no significant in-hospital mortality difference between the weekend and weekday admissions on both univariate and multivariate analysis.

CONCLUSIONS

Weekend AP admissions develop more severe complications requiring intensive care. Despite this, there was no weekend effect for in-hospital mortality for AP-related admissions.
