The Safety-II framework uses a proactive approach to improving patient safety by learning form what goes right in healthcare. This article summarizes the attributes of the Safety-II framework and outlines the challenges and opportunities related to integrating Safety-II within healthcare settings.

Human error can affect the safety of care delivery. This article provides an overview of human error, the theories and methods available to understand, prevent, and mitigate human error, and the role of ergonomics and human factors in reducing error.

Safe workplaces, and employees who work safely, are an important component of patient safety. This study explores new employees’ safety learning in three sectors, including care of older adults. Organizational and informal safety training and learning are discussed.

Assessing safety climate is critical to understanding how organizational efforts can improve safety. This review identified deficiencies and inconsistencies in the way that safety climate has been conceptualized and measured. The authors underscore the importance of a consistent approach to measuring safety climate in order to evaluate its impact on patient safety outcomes.

Transfusion errors can have serious consequences. This study compared wrong blood in tube (WBIT) errors in 9 countries across three settings: emergency department, inpatient, and outpatient. Results show emergency department WBIT errors were significantly higher in emergency departments, and that electronic positive patient identification (ePPID) significantly reduced WBIT errors in the emergency department, but not in inpatient or outpatient wards.

Overuse, overdiagnosis, and overtreatment pose a continuing threat to patient safety. Citing several contributors to overuse at the system, clinician, and patient levels, this commentary discusses potential solutions including the Choosing Wisely campaign and patient education.

Medication safety in children is a patient safety priority. This systematic review explored interventions to reduce medication dispensing, administration, and monitoring errors in pediatric healthcare settings. The majority of identified studies used “administrative controls” to prevent errors, but those implementing higher-level interventions (such as smart pumps and mandatory barcode scanning) were more likely to result in error reduction.

This article reviews the theory behind the Swiss Cheese Model and how organizational influences, supervisory factors, preconditions for unsafe acts, and unsafe acts threaten patient safety.
