Fragmentation isn't a rare failure — it's the default state of complex care. A medication prescribed for one condition worsens another; a test is read without the full context; a referral dies in a fax queue. I've lived every one of those cracks. Coordination work means one person holds the whole picture and pays attention to all the details, so the system's gaps stop becoming your emergencies. When care moves into a hospital or surgery setting, that same whole-picture attention helps you prepare, ask informed questions, communicate with the care team, and leave with a clear discharge plan.
