Comparative Study
Evaluation of a clinical decision support system for glucose control: impact of protocol modifications on compliance and achievement of glycemic targets.
Treating hyperglycemia may improve patient outcome, but is a clinical challenge. Three variations of a computerized insulin protocol were compared with regard to protocol compliance and achievement of glucose target levels. In group 1, the existing protocol was applied, in group 2 the protocol was modified to account for decreasing glucose values; group 3 had a higher threshold for initiating insulin, wider glucose target ranges, and included instructions to regulate glucose around mealtimes. ⋯ Average glucose levels increased in group 3 due to a higher threshold for starting insulin and a wider target range: 70% (group 1), 66% (group 2), and 61% (group 3) had an average glucose of <8 mmol/L (P < 0.001). Also, we observed a decreasing trend in incidence of hypoglycemia and reporting of noncompliance. Further improvements in glucose measurement technology and protocols are needed to optimally treat hyperglycemia in the Intensive Cardiac Care Unit.

Adherence to evidence-based guidelines for the treatment of coronary artery disease (CAD) is suboptimal. Our goal was to determine whether the performance achievement award program for Get With The Guidelines-Coronary Artery Disease (GWTG-CAD) was associated with global and sustained adherence to evidence-based guidelines for acute myocardial infarction. ⋯ In conclusion, the performance achievement award program for GWTG-CAD was associated with global and sustained adherence to evidence-based guidelines. Our data suggest that this tool is a useful component of a quality improvement initiative and should be considered for other similar programs.

Low-risk emergency department (ED) chest pain patients with a nondiagnostic electrocardiogram (ECG) and negative cardiac biomarkers are commonly evaluated with cardiac stress testing to detect undiagnosed coronary artery disease. Provocative testing incurs certain costs and may require additional time investment either in the ED or in an observation setting. Recent research has questioned the utility of provocative testing in young adults with negative cardiac biomarkers and nondiagnostic ECG. We sought to evaluate the utility of cardiac stress testing in our population of young adult patients with chest pain. ⋯ The population of chest pain patients younger than 40 years with no history of coronary disease, a nondiagnostic ECG, and negative serial biomarkers may not benefit from provocative testing. Our findings complement those reported previously on the limited utility of cardiac stress testing in this population.

Primary percutaneous coronary intervention (PPCI) is the preferred method of reperfusion for ST-segment elevation myocardial infarction (STEMI), if it can be performed in a timely manner by an experienced interventional cardiologist at a high volume STEMI Receiving Center. However, an estimated 50% of STEMI patients present to STEMI Referral Centers without PPCI capability. ⋯ Nonetheless, transfer of STEMI patients for PPCI has not been used extensively in the United States and is associated with markedly prolonged transfer times. This study demonstrates that rapid transfer of STEMI patients from community hospitals without PPCI capability to a STEMI Receiving Center is both safe and feasible using a standardized protocol with an integrated transfer system.
