Complications on the increase for stroke hospitalizations

Abstract

Free abstract

MedWire News: US study findings indicate that complication rates among patients hospitalized for stroke have gone up in recent years.

Patients hospitalized for stroke in 2006–2007 were more likely to experience acute myocardial infarction (AMI), deep vein thrombosis (DVT), pulmonary embolism (PE), and urinary tract infection (UTI) than patients hospitalized 8 years earlier, researchers report.

Xin Tong (Centers for Disease Control and Prevention, Atlanta, Georgia) and colleagues analyzed data from the 1998 to 2007 Nationwide Inpatient Sample of the Healthcare Cost and Utilization Project, which included 1,150,336 adult hospitalizations with ischemic stroke as a primary diagnosis.

In 2006–2007, the prevalence of hospitalizations with a secondary diagnosis of AMI, pneumonia, DVT, PE and UTI was 1.6%, 2.9%, 0.8%, 0.3%, and 10.1%, respectively.

Compared with 1998–1999, the adjusted odds ratios (ORs) for hospitalization in 2006–2007 complicated by AMI, DVT, PE, or UTI were 1.39, 1.68, 2.39, and 1.18, respectively. The odds of pneumonia did not change significantly over this period, however.

In-hospital mortality was significantly lower in 2006–2007 than in 1998–1999, with an adjusted OR of 0.75. Despite the overall length of stay decreasing significantly from 5.56 days in 1998–1999 to 4.77 days in 2006–2007, it remained the same for hospitalizations complicated by AMI, pneumonia, DVT, and PE.

Tong et al comment in the journal Stroke: “There is clearly a need for further investigation of the sociodemographic, clinical, and healthcare factors associated with these conditions during hospitalizations with ischemic stroke.”
