Nosodromosia: the epidemiology

A patient arrives at your clinic already unsettled. She is late, flustered and her blood pressure is up. None of it is about her health. She has spent twenty minutes lost in a building she does not know, and she has brought that stress into the room with her.

There is no diagnostic code for this and no entry in the textbooks, so we have given it a name: nosodromosia, the anxiety, disorientation and cognitive distress of becoming lost inside a hospital. The word is new. The problem is not, and the evidence for its effects is well established.

Poor wayfinding is a recognised source of physiological stress, including raised blood pressure and heightened anxiety in the moments before a clinical encounter (Ulrich et al., 2010; Lee et al., 2020). Read as an epidemiologist would read it, the pattern is clear. It is

widespread, unevenly distributed and largely preventable.

• It compromises the encounter itself. A blood pressure taken minutes after a frantic search is harder to trust. Recall is poorer and patients absorb less of what they are told, so the consultation begins at a disadvantage before a word is spoken.

• The burden is not evenly shared. It falls hardest on older patients, people with visual impairments, hidden disabilities and cognitive difficulties, and on anyone attending for the first time. The more complex the site, the greater the risk. Wayfinding is, in effect, an equity issue.

• The cost reaches staff as well as patients. Every lost patient asks for help, and every nurse, porter and receptionist who stops to give directions is drawn away from the work they trained for. One landmark study put the staff time spent giving directions in a single large hospital at more than 4,500 hours a year (Zimring, 1990).

• The knock-on effects are familiar to any clinic: late starts, missed appointments, rescheduling and the pressure that flows down a list for the rest of the day.

The encouraging part is that the cause sits in the environment, not the patient. Change the environment and the distress largely goes with it.

At a large hospital on the south coast, where RouteLoop is being piloted, patients told us what that change feels like. One had come to expect raised blood pressure at every appointment, simply from the strain of finding her way. With clear directions from the moment she arrived, that stress lifted. Her health was no different; the hospital around her had simply become easier to navigate.

RouteLoop, designed by Superspree, gives step-by-step directions on any smartphone from the moment someone walks in, with no app to download, no registration and nothing to learn. Accessible routes, including step-free options, are built in from the outset rather than added afterwards.

Nosodromosia is not inevitable. It is a fault in the building, not the patient, and faults can be fixed. Put it right and care begins the moment the patient sits down, not once they have recovered from finding you.
