a shift in power from the individual to the collec-
tive. Collective intelligence is not a new idea, but
it has received a new meaning through the emer-
gence of Web 2.0 applications (Leimeister, 2010).
This new meaning depicts the ability for people digi-
tally connected by the internet collectively to create
knowledge. There have been instances of amateur
knowledge surpassing professional knowledge, and
Wikipedia is given as the most recognised example of
this (Surowiecki, 2005; Boulos and Wheeler, 2007).
In relation to healthcare, collective intelligence
can improve evidence based medicine by drawing
on a larger knowledge base (Tapscott and Williams,
2008). Online networks enrich and contextu-
alise health information and reduce misinformation
(Aghaei et al., 2012; Boulos and Wheeler, 2007;
Hughes et al., 2008). Similarly, collective intelli-
gence might be the solution to concerns about health
information quality. As thousands of bloggers ex-
change ideas daily they are effectively acting as filters
for information-overloaded Web surfers (Boulos and
Wheeler, 2007).
Mass participation is central to the ideas of social
computing and collective intelligence. This assump-
tion is however subject to criticism. In reality only a
small proportion of users may actually be active pro-
ducers (Dijck and Nieborg, 2009). Also, mass partic-
ipation must ensure that the individual is not hypno-
tised by the crowd (Le Bon, 1897).
3.7 Web 4.0
The Web is evolving far beyond Web 2.0 to Web 4.0
(Aghaei et al., 2012; Patel, 2013; Choudhury, 2014).
Web 4.0 is described as the symbiotic Web in which
the human mind and machines can interact symbiot-
ically, including Medicine 4.0 and its links to human
city interaction (Choudhury, 2014; Naphade et al.,
2011; Roche and Rajabifard, 2012).
4 HUMAN-SOCIAL CHALLENGE
Certain social system problems are ill formulated,
have many different clients or agencies with conflict-
ing values, and have been referred to as ‘wicked prob-
lems’ (Churchman, 1967; Rittel and Webber, 1973).
Health services (in particular cancer services) are
such a wicked problem (Ferlie, 2013). Human city
interaction and its interplay with cyber-physical sys-
tems realises the collaborative user interactions that
are similarly of benefit to healthcare (Xia and Ma,
2011; Cockerham, 2005). The wicked problems how-
ever present number of human social challenges that
can be usefully considered by referring to the theory
of structurisation that we met earlier.
4.1 Structuration and Wicked Problems
Structuration Theory connects directly to the idea
of addressing wicked problems (van Veenstra et al.,
2014). Structuation uses the term routinization to de-
scribe the idea of structure being continuously pro-
duced and reproduced through action. Through re-
peated actions a social order is established and certain
patterns of behaviour and ways of engaging in tasks
become institutionalised (Giddens, 1984). From rou-
tinization in healthcare we might conclude that there
are necessary structural constraints upon both patients
and professionals that might be preventing them from
moving towards a perfectly collaborative position.
Medicine 2.0 introduced the idea of including
patients and professionals working more closely to-
gether, but routinization may still be evident in the
cyber-physical models of healthcare. It has been as-
sumed that patients will simply behave as required for
the efficiency gains from healthcare cyber-physical
systems to be achieved (Broy et al., 2012). How-
ever, for the efficiency to be harnessed a wide variety
of complex social factors need to be considered in-
cluding psychological factors linked to human inter-
actions and lifestyle habits that have developed over
time. This assertion is supported elsewhere, as health
lifestyles are not the uncoordinated behaviours of dis-
connected individuals, but are routines linked to inter-
actions within groups (Cockerham, 2005).
After IT systems have been adopted, they need to
be assimilated to change existing work practices. Un-
til this has happened productivity may decline and if
innovation is not successfully assimilated they could
be worse off as previous successful routines will have
been lost (Setia et al., 2011). Further support arises
from social constraints, both in relation to cyber-
physical systems and IT artefacts that are shaped
by messy processes. Rather they are influenced by
the social system they are embedded in. Further-
more cyber-physical systems are particularly uncon-
trollable due to feed- back loops and the behaviour
of some parts of the system being difficult to predict
(Beverungen, 2013).
Perhaps more significant than the issue of integrat-
ing patients into a new health system based on human
city interaction are the cultural factors that impact
on the behaviour of healthcare professionals. Resis-
tance to change and conformity to routinization may
emerge from the desire to hang onto power and sta-
tus linked to current structures, reinforced by the per-
ception that change is just part of the government’s
