Hospital process maps tend to go blank in the same places: the corridor, the elevator, the twenty minutes a patient spends between one department’s care and another’s. These are treated as connective tissue, mere transport between the parts of the map where the real work happens. They are, in fact, where a surprising share of the harm lives, for one plain reason. They are exactly the spaces where clinical ownership lapses.
Follow a ventilated patient from the ward to imaging and watch the ownership evaporate. On the ward, a nurse owns them. In the scanner, a technologist owns them. In the hallway between, with the infusion pump running on battery and the oxygen coming from a cylinder that somebody set by eye, nobody owns them at all. Every department upstream assumed the patient was about to arrive somewhere safe, and every department downstream assumed they had not left yet, and the map has no box for the place where both assumptions are false at once.
This is why the most useful way to hunt for hospital risk is to follow the patient rather than the organisation chart. The org chart is a map of who owns what. The patient’s journey is a map of where ownership is handed over, and the handoffs are where people get hurt. Trace an admitted patient held in the emergency department waiting for a bed, and you find someone caught between two work-as-imagined models: the emergency department’s processes assume she is leaving any minute, so the scheduled inpatient care never triggers, while the inpatient unit’s processes assume she has not arrived, so she is on no one’s rounding list, no one’s medication pass, no one’s turning schedule. Every characteristic harm of boarding falls out of that single structural gap.
The disciplines who work these in-between spaces are the least invited to risk analyses and among the most information-rich, precisely because they live where the ownership fails. The transporter knows what actually travels with a patient and what gets left behind. The environmental services technician knows which isolation flags arrive too late for the room turnover to matter. They hold maps of the territory no committee has ever asked to see, because the committee is organised by department and the territory is the space between departments.
The practical instruction is small and changes what you find. When you scope a risk analysis, do not draw the fence around a department. Draw it around a stretch of the patient’s journey, and make sure it includes the corridors, because a map that stops at each department’s door has quietly excluded the ground where the patient is most alone.
Two chapters of Before Harm Happens are given over to these crossings, inside the hospital and beyond it, for the simple reason that the arrows carry more risk than the boxes.
