Question
Hypothetical follow-up
Let's say researchers determined that there was slightly more confusion in visitors when a booth
with no staff and a sign was present, relative to a fully-staffed booth, but there was a LOT more
confusion when the booth was unstaffed and there was no sign. As a result, they recommended
that the unstaffed+sign scenario become the permanent situation at hospital entrances other than
the main entrance.
To determine whether this change was effective, they compared the results of the annual "visitor
satisfaction survey" from this year (after the change was made) with results from the 3 years
prior. They found that satisfaction around "signage and information" was significantly worse this
year than it was before. This was true regardless of visitors' ages or reasons for visiting the
hospital.
