The hospital emergency department (ED) is a risky environment, often subjec
t to litigation for negligence. Risk is defined as an avoidable increase in
the probability of an adverse outcome for a patient. With the aim of ident
ifying the sources of risk, this study carried out participant observation
and collected critical incidents in two EDs in the UK for a period of 30 mo
nths. Active failures included delay in beginning investigations or treatme
nt, failure to obtain diagnostic information, misinterpretation of diagnost
ic information and the administration of inappropriate treatment. Three lat
ent conditions underlay these failures: patients' unrestricted access to th
e ED, cognitive errors by individual members of staff and a strict horizont
al and vertical division of labour. An analysis of the incidents resulting
from the third latent condition identified a contradiction between the divi
sion of labour and working conditions in the ED. The paradigm circumstances
under which this contradiction can result in active failures are described
. The management of risks arising in this way could be improved by developi
ng a workplace culture in which 'sapiential authority' - authority derived
from experience, special access to information or being at hand in an emerg
ency - is recognised in addition to authority derived from a formal status:
However, as long the contradictions between the division of labour and wor
king conditions remain, accidents should be considered normal events. (C) 2
