Thirdly actors use the obligatory passage point because it provides the best outcomes for their field of interest. An obligatory passage point ‘has to be broad enough to be interpreted by a diversity of actors [and] as the solution to a range of problems’ (Linderoth, 2009, p. 67). Linderoth noted this in his study of an engineering firm carefully considering mandating an automated software program into engineering teams involved in building construction. He reports that engineering teams are composed of a variety of different people and groups, all of which have different specialties, focuses, challenges and problems. Any mandated automated software program would have to not only accommodate these, but also be seen by the various users as the solution to their specific needs. This situation exists for all actors and groups in the healthcare system arena. Actors enter and exit the arenas, a multitude of mental health presentations, issues and concerns arise, they are fluid in their clinical status, there can be periods of under-resourcing, chaos and unpredictability. Different actors have different focuses. The remote nurse as the obligatory passage point has to be, with the consensus of the actors, their best solution. This does not necessarily mean it results from careful or deliberate design. More likely, remote nurses assume the obligatory passage point from simply being present in remote locations. As it transpires all actors and groups find in the circumstances, this is the best solution. The researcher found one published study involving nursing which used obligatory passage points as a means to describe their findings. Allen’s (2015) ethnographic study examined the work practices, knowledge construction and organising functions of acute nurses (of varying managerial status), in different departments of a large metropolitan
