Between-group behaviour in health care: gaps, edges, boundaries, disconnections, weak ties, spaces and holes. A systematic review.

Summary: In healthcare, "mind the gap" isn't just a warning for subway passengers; it's a crucial concept for hospitals and clinics. Usually, when we see a gap in communication or a disconnect between departments (silos), the immediate instinct is to patch it up. However, this review suggests we should look closer before we build bridges. By studying these "structural holes" and "weak ties" between medical teams, leaders can understand exactly where and why communication breaks down. Instead of blindly filling holes, analyzing these disconnects reveals specific opportunities to strengthen the entire fabric of the organization, leading to better knowledge sharing and stronger professional relationships.
