Final answer:
The Joint Commission investigation found poor teamwork and communication to most frequently cause medical errors due to factors like work overload and bureaucracy.
Step-by-step explanation:
A Joint Commission investigation found that poor teamwork and communication were the most common root causes for Medical errors. This is supported by various factors in healthcare settings, such as work overload, unsafe work environments, frustration with bureaucracy, and excessive paperwork. These conditions can lead to decreased team efficiency, making it challenging for healthcare professionals to apply their knowledge accurately in urgent and complicated situations. Hence, the right answer is B) Medical errors.
The impact of these challenges extends to the entire healthcare delivery process. For example, the team halo effect can make teams appear to work better than they do, masking inefficiencies and individual member underperformance. Intended positive aspects of bureaucracies, like increased productivity and efficiency, can be undermined by these systemic issues, leading to a significant detriment to patient care.
