Yes, I believe that in the US, the stress related to paperwork demands and daily patient quotas results in poor attitudes and excessive stress among many health care workers. Research has shown that this situation leads to a decrease in the quality of patient care. My wife is studying the use of a technique called "mindfulness" that health care workers may use to decrease their own stress levels, and at some point teach their patients the same technique. Research has also shown that many patients with chronic diseases benefit from this mindful behavior.
One way that the communication channels between, especially between interdisciplinary healthcare workers, is to use checklists where the team members stop to acknowledge all the members individually prior to engaging in complex care interventions such as surgery. This strengthens the ability for lower ranked members to speak up in the event of a problem, etc. this is one of the key points on the WHO surgical checklist. See "the Checklist Manifesto" by Atul Gawande for more details.
