Relationship between a risk score for QT interval prolongation and mortality across rural and urban inpatient facilities.
The objectives of this retrospective observational study were to evaluate the relationship between a modified Tisdale QTc-risk score (QTc-RS), inpatient mortality, and length of stay in a broad inpatient population with an order for a medication with a known risk of torsades de pointes (TdP). Inpatient data from 28 healthcare facilities in the western US were used. The results indicated that there is a strong relationship between increased mortality as well as longer duration of hospitalization with an increasing QTc-RS.

Effect of acute stroke care regionalization on intravenous alteplase use in two urban counties.
Investigators sought to determine whether increasing access to primary stroke centers (regionalization) led to an increase in intravenous alteplase use in acute ischemic stroke patients. Studying two urban counties in the western region of US that regionalized acute stroke care, they found that in Santa Clara County, intravenous alteplase was administered to 1.7% of patients in the pre-regionalization period and 2.1% in the post-regionalization period, while in San Mateo County, the numbers were 1.3% and 3.2%, respectively. In the post-regionalization phase, San Mateo County had greater change in paramedic stroke detection, higher number of transports to primary stroke centers, and more frequent use of intravenous alteplase at stroke centers. They concluded that greater post-regionalization improvements in San Mateo County contributed to significantly improved county-level thrombolysis use than Santa Clara County.

Understanding of cardiovascular disease risk factors among Bangladeshi immigrants in New York City.
This study’s objective was to compare the understanding of cardiovascular disease (CVD) risk factors among Bangladeshi immigrants to the general Caucasian population in the U.S. by surveying a sample group of immigrants in Queens, NY., Scores on the knowledge instrument used for the surveyed Bangladeshis were compared with Caucasians from the Coronary Artery Risk Development in Young Adults (CARDIA) study using multivariate regression modeling. The results of the study indicate that understanding of CVD risk factors was lower among Bangladeshis than whites, driven by the surveyed Bangladeshis having less awareness of how exercise and weight contribute to CVD risk. The authors recommend that community based interventions and health partnerships target these behavioral risk factors in the Bangladeshi population.

Quality of cardiovascular disease care in small urban practices.
This study described small, independent primary care practices' performance in meeting the Million Hearts ABCSs (aspirin use, blood pressure control, cholesterol management, and smoking screening and counseling). It concluded that achieving targets for ABCS measures varied considerably across practices; however, small practices were meeting or exceeding Million Hearts goals (i.e., 70 percent or greater).

Characteristics of automated external defibrillator coverage in Philadelphia, PA, based on land use and estimated risk.
The authors investigated how well the likelihood of out-of-hospital cardiac arrest was met by the supply of automated external defibrillators (AED) in a dense urban environment. This article offers one method by which local officials can use spatial data to prioritize attention for AED placement and coverage.
