The number of devices with alarms has multiplied in recent years, causing alarm fatigue in bedside clinicians. Alarm fatigue is now recognized as a critical safety issue. ⋯ Since 2005-2006 when the first survey was conducted, not much has changed. False alarms continue to contribute to a noisy hospital environment, and sentinel events related to alarm fatigue persist. Alarm hazards are a significant patient safety issue.

Rapid response systems (RRSs) aim to identify and rescue hospitalized patients whose condition is deteriorating before respiratory or cardiac arrest occurs. Previous studies of RRS implementation have shown variable effectiveness, which may be attributable in part to barriers preventing staff from activating the system. ⋯ The results of this study provide an in-depth description of the barriers that may limit RRS effectiveness. By recognizing and addressing these barriers, hospital leaders may be able to improve the RRS safety culture and thus enhance the impact of the RRS on rates of cardiac arrest, respiratory arrest, and mortality outside the intensive care unit.

Glycemic control in cardiac surgery: implementing an evidence-based insulin infusion protocol.
Acute hyperglycemia following cardiac surgery increases the risk of deep sternal wound infection, significant early morbidity, and mortality. Insulin infusion protocols that target tight glycemic control to treat hyperglycemia have been linked to hypoglycemia and increased mortality. Recently published studies examining glycemic control in critical illness and clinical practice guidelines from professional organizations support moderate glycemic control. ⋯ Increasing nurses' knowledge of glycemic control and implementing an insulin infusion protocol targeting moderate glycemic control were effective for treating acute hyperglycemia following cardiac surgery with decreased incidence of hypoglycemia.
