**6. Topics in the current book**

The current text contains some unique and perhaps under-appreciated topics. Beginning with "anatomy of medication errors", there are unique chapters on patient safety culture in primary care practices, PS perspectives in the context of health-care operations and risk management, alarm fatigue, the importance of air filtration systems, and even medical radiation safety (both diagnostic and therapeutic). Although seemingly diverse and unrelated, the common thread among the chapters of this final volume of **The Vignettes** is the continued demonstration of the critical importance of teamwork within our increasingly complex health-care systems. Again highlighted are the key elements of communication, collaboration, and coordination [65–67].
