Building a successful team requires effort but yields significant benefits. Effective team building can prevent up to 80% of medical errors through improved coordination. Implementing an eight-hour team building course for one emergency department staff resulted in a 58% reduction in errors. Key aspects of building a strong team include selecting the right size of 10 people or less, establishing ground rules to create a safe environment, considering all ideas as valuable, and encouraging cooperation and communication to improve relationships over time. Ongoing attention to team building is important as needs change.
