AbstractÐThis paper is based on an empirical study of attempts to achieve change in clinical behaviouracross a United Kingdom National Health Service (NHS) Health Authority (HA). We suggest that theevidence based medicine (EBM) movement underpinning such attempts is premised upon a highlyrationalistic conception of change. Here the generation and implementation of research ®ndings intoclinical practice is understood as movement between discrete entities. Drawing upon poststructural phil-osophy, social studies of science and technology, social anthropology, and gender studies, we challengesuch linear perspectives through a more immanent alternative. We conceive of change as movementwithin indeterminate or ambiguous relationships. We then proceed to discuss the implications of thismodality for the management of clinical behaviour change. # 1998 Elsevier Science Ltd. All rightsreserved

INTRODUCTION
Following a 1988 report by the House of Lords
Select Committee on Science and Technology, a
U.K. National Health Service (NHS) research and
development (R&D) national strategy was launched
in 1991 (Central Research and Development
Committee, 1995; Department of Health, 1995).
Arising out of this strategic programme, there is
increasing policy level interest in the evidence based
medicine (EBM) movement, which argues for the
generation of research evidence and the implemen-
tation of its ®ndings where these could make clini-
cal practice more e�ective. The implementation of
such EBM principles, however, depends on an abil-
ity to achieve signi®cant and planned clinical beha-
viour change. This raises interrelated issues of
professional power, scienti®c knowledge, and clini-
cal interests, especially where the interface between
research and practice is revealed as problematic.
From a social science point of view, some EBM
arguments can be seen as overly mechanistic and
rationalistic: linear ``technology transfer'' models
which assume a non problematic relation between
the R&D base and clinical behaviour change.
Evidence in this context is taken to be both discrete
and isolatable; an unequivocal and empirically
tested explanation of the clinical world and its mo-
tivating mechanisms. However, these models may
underestimate the impact of other confounding cir-
cumstances. In particular, a number of organis-
ational and behavioural factors, such as the
institutional and ®nancial arrangements in a setting;
the resources, skills and competencies available to
access scienti®c information; the motivation to
overcome discipline, geographical and cultural bar-
riers; will all in¯uence the extent to which it is poss-
ible to change patterns of clinical practice in a
planned direction (Dawson, 1995). Nor is the scien-
ti®c base of clinical research always incontroverti-
ble, as long running and unconcluded scienti®c
controversies are apparent in certain clinical and
medical ®elds, as participants attach di�erent mean-
ings to available scienti®c knowledge (Dawson,
1995).
This paper sets out to examine these scienti®c, or-
ganisational and behavioural factors, in order to
highlight the problematic connection between the
generation and implementation of biomedical
research. Drawing centrally upon the distinct, yet
related, poststructural ideas of Gilles Deleuze and
Jacques Derrida, we consider how the perceived
``Cartesian gap'' between research and practice has
become ubiquitous, before discussing whether we
should talk of a research/practice gap at all, or of
the division that separates and yet connects them.
Illustrating our argument with examples drawn
from substantial empirical work, we suggest that
rather than being a pure source, research evidence
informs, and is informed by, a heterogeneous
framework of political power, professional knowl-
edge, and agency interests. We conclude that mean-ing is not an inherent property of information and,
therefore, that evidence is not put into practice
(Watson et al., 1995). This corresponds with the
poststructural view that theory cannot be placed

outside practice and highlights the need to moveaway from linear transfer models and towards more
¯exible modalities, in which both are seen as necess-arily cyclically paired (Watson et al., 1995).
BODIES OF EVIDENCE?
Reports of biomedical research point to the cen-trality of science and its neutrality in producing for-mal, objective accounts of knowledge. Such
accounts continue to be dominated by a long stand-ing, Cartesian epistemology of di�erentiation ± areality of distinct subjects and objects ± in whichresearch evidence and clinical practice are seen as
dualistically opposed. Evidence, in this context, isseen as a commodity, whose better, quicker, easierto access, and increasingly electronic transfer, from
the research pole to that of practice will lead to themore e�ective clinical management of patients (see,for example, Smith, 1996). Whilst the appeal of this
dualist model is its maintenance of stable bound-aries and ®rm divisions: objective/subjective,research/practice, facts/values, such thinking isalmost always structured so as to privilege one side
of the dualism over the other. This has made poss-ible the hierarchical distinction between, forexample, the objective ``facts'' of biomedical
research and the subjective ``mere knowledge'' ofclinical practice (Lomas et al., 1993; Haines andJones, 1994). Here, an analytic and disembodied
(scienti®c) organisation of knowledge is privilegedover more tacit and situated experiences: a body ofevidence, separated from its social context, that can
be unilaterally transmitted from the research setting± where it is known ± to the world of practice ±where it is not.Social studies of science, however, have long been
interested in the content of scienti®c work, ratherthan simply its ideological claims. Early work in theUnited States by Merton (1973) on citation analy-
sis, suggested that science was indeed ``disinterested,communistic, and universal''. Meanwhile in theU.K., studies were concerned to show that scienti®c
work was not neutral, communicative, nor uni®ed,but determined more by structural arrangements,political commitments, and institutional interests.These studies were exempli®ed by the ``strong pro-
gramme'' (Bloor, 1976) in the sociology of scienti®cknowledge and have become associated with the``Edinburgh School'' (Barnes, 1977). These and
other works (see for example, Mulkay, 1972;Pickering, 1984; Collins, 1985) proposed an inver-sion in the traditional relationship between science
and nature. They suggested the representationalpractices of science constituted the objects of theworld, rather than being their simple re¯ection
(Woolgar, 1988). For them, science was socially andhistorically constructed.Precisely because these approaches accept the
constructivist thesis, however, they incorrectly
retain an ontological commitment to a discrete andconceptually isolatable natural world made up of
objects, and a constitutive social world made up ofpeople (Latour, 1993, 1998). By adopting the relati-vist position that nature re¯ects and embodies so-
ciety, they ignore the ontological and oftenrecalcitrant character of nature. That is to say,whilst they invert the traditional realist hierarchy:
society re¯ects nature, they simply replace it withanother: nature is constituted by society, and sopreserve the Cartesian di�erence between them.
There have been an increasing number ofapproaches, however, that have sought to questionthis duality. Drawing on poststructural philosophy(Deleuze and Parnet, 1987; Derrida, 1978, 1987;
Deleuze and Guattari, 1988), social studies ofscience and technology (Callon et al., 1986; Latour,1987), social anthropology (Strathern, 1991), and
gender studies (Anzaldu a, 1987; Haraway, 1991),notions of ®xedness and certainty have begun to beswept away, signalling instead a destabilisation of
boundaries and a dislocation of centred identities.Through them, attention has been paid to under-standing evidence not as a necessarily independent
and enduring source, but as a transient moment inan indeterminate process of stabilisation and desta-bilisation. These approaches posit that no matterhow discrete and pre-existent its appearance, evi-
dence is always inextricably combined with theactions, interactions and relationships of clinicalpractice. That is to say, following Latour (1987),
that a body of established evidence should not beunderstood as representative because it is true.Instead, a body of evidence is established as true
precisely because it is held to be representative.
METHODOLOGY AND STUDY DESIGN
The objectives or our research were two-fold.First, to study the career of four acute sector in-
itiatives designed to secure changes in clinical prac-tice across a U.K. Health Authority (HA). Second,to establish the relative uptake/impact of each in-
itiative, so as to assess their relative success insecuring change. The project utilised a qualitativeand comparative, two-stage case study method-ology, and the four change issues encompassed a
mix of medical and surgical initiatives and instancesof favourable and less favourable or contested eva-luative evidence (Wood et al., 1998).
Whilst this methodology cannot o�er statisticalgeneralisability, it is better suited to an in-depthanalysis of the complexities of iterative and uncer-
tain change processes, unfolding over time andbetween settings (Pettigrew, 1985). This can bemissing in a more super®cial, quantitative analysis
of a larger data set, typical of randomised con-trolled trial (RCT) methods. RCTs may be widelyapplicable within biomedical and pharmacologicalresearch, however they are premised upon a
Martin Wood et al.1730
Mertonian notion of science as disinterested, com-munistic and universal. In this view, the disinterest-
edness of a disciplinary community works toguarantee the universality of science by separatingknowledge itself from both the speci®c, local situ-
ation of its production, and its uniform applicationas scienti®c knowledge (Lave and Wenger, 1991).Instead, we have sought to locate our empirically
derived data within a deliberate, interpretativeframework. Whilst this is based upon detailedempirical enquiry, it does not rely on an over
simple revelatory model of social science (Giddens,1979), grounded within a purely inductive function-alist methodology (Wilson, 1970). The often com-plex, necessarily open-ended and sometimes
incommensurable, views of a range of di�erent sta-keholders: their pasts, current preoccupations andmotivations, are necessarily framed as indeterminate
texts (Kets de Vries and Millar, 1987). This methodis more sensitive to the interconnectedness of sys-tems as a whole. It seeks to maintain the continuity
of networks, rather than to create and employ wellde®ned categories: ``scienti®c'', ``political'', ``legal'',``economic'', ``social''.
Stage 1 of the research design comprised a broad,exploratory, sweep of the four clinical change in-itiatives across the region. Stage 2 consisted of amore intensive analysis of a particular acute setting
for each of the four initiatives. Accordingly, twosemi-structured interview schedules were developedand used with a total of 119 respondents. To reduce
variance and allow comparative analysis, these wereissue speci®c and represented a customised versionof the common schedule adapted for each of the
four cases. This was supplemented by secondaryanalysis of published material, including guidelines,trial results, retrospective exchanges of letters tojournals, non-participant observation; and ad hoc
discussion.
CHARACTER AND OUTCOMES OF THE CASE STUDIES
In this section we review the history, character,
and outcomes of each of the four change initiatives.This will provide the context(s) for a subsequentanalytical discussion of the data to follow.
Managing anticoagulation service provision
Evidence suggests that stroke is the third mostcommon cause of death in the U.K. after ischaemic
heart disease and cancer. According to the BritishSociety for Haematology (1989) Guidelines on OralAnticoagulation, there is strong clinical evidence
that a signi®cant proportion of ®rst strokes can beprevented by treatment with an appropriate oralanticoagulant such as Warfarin, which prevents
thrombo-embolism (coagulation or clotting of theblood). Moreover, there appears little controversythat the demand for long-term oral anticoagulanttherapy is rising exponentially as the indications for
patients with a higher risk of stroke are widened,and the expected volume of treatment increases.
What is equivocal, however, is how best to managethe growing logistical and ®nancial pressures ofdelivering such a widespread and, potentially, long-
term therapy.Speci®c interventions remain limited, and those
that do exist have ``ring fenced'' funding and con-
cern only a small number of pilot studies. Howeverthose that have been conducted indicate thatadvances in near-patient testing techniques and
computer based information and advisory systemswould enable the safe and e�ective transition of thelong-term management of anticoagulant therapyfrom a clinical to a medical responsibility and from
acute to outreach managed, primary care settings(FitzMaurice et al., 1996; Vadher et al., 1997).Furthermore, this service modality is seen as ®tting
broader policy shifts away from hospital stays andtowards more community based and locally accessi-ble care and services. Yet despite these favourable
indications, current initiatives remain slow moving.Why should this be so? And, what are the impli-cations for the relationship between research evi-
dence and clinical change?
Impact of the ``Changing Childbirth'' document onobstetric care
Historical concern for infant mortality rates hasled to a shift in the location and processes of sup-
port for women in childbirth from home to mater-nity unit. As childbirth shifted to a hospital setting,so the role and importance of technology and
obstetrics grew. Concomitant with this rise was thedemotion and marginalising of the role of the mid-wife. As a result, there is a long history of obstetriccare, which has progressed through stages of devel-
opment and become increasingly professionalisedand ``medicalised'' (Richards, 1975). But it is anarea of clinical practice which has many contestable
practices. Most signi®cantly of all are major contro-versies around where care is provided and who pro-vides it. Most recently these di�erent views have
been incorporated into a speci®c, national initiativeconcerning the care of women during childbirth,resulting in the production, in 1993, of aDepartment of Health document entitled Changing
Childbirth. This document contains a number ofprecise recommendations regarding targets andchanges in practice. It also sets out a timescale for
the ful®lment of these objectives.However, to implement the changes proposed
often requires a considerable shift in the roles and
interactions between members of di�erent pro-fessions, namely the obstetricians and the midwives.Here, there is evidence that the Changing Childbirth
document has had impact, is quoted and widelyknown and has created debate amongst many pro-fessionals in the area. Although there are still widevariations in practice, there is some, albeit limited,
Clinical behaviour change 1731
evidence that it is being enacted. Successful im-plementation has occurred in those maternity units
where the use (and in some instances the introduc-tion) of jointly prepared and jointly agreed guide-lines and protocols, together with good group and
inter-professional relationships, which have beenbuilt up between medical sta� over time, have beencombined.
The use of laparoscopic surgery for inguinal herniarepair
The commonest hernia is the inguinal hernia. Itinvolves organs of the abdomen extruding throughthe abdominal lining into the groin. This is tra-
ditionally repaired by laparotomy involving theopening of the abdomen above the groin through a10 cm incision, returning any herniated organs to
their proper place and repairing the defect withsutures. More recently, inguinal hernia repair hasinvolved experimentation with mono-®lament``open'' mesh repairs and ``closed'' or ``keyhole''
laparoscopic techniques. The latter allows the abdo-men to be examined and repaired by inserting asimilar mono-®lament mesh through three small
tubes ± ports ± which in turn are inserted throughsmall holes made in the abdominal wall, therebyreducing the physical trauma of access associated
with the open laparotomy (Stuart, 1994).Laparoscopic inguinal hernia repair (LIHR)
developed rapidly despite being the subject ofintense scienti®c controversy and volatility. Central
to this development have been the body of generalsurgeons themselves. They exhibit a strong sense ofprofessional individualism and craft based expertise,
within a framework of collegial governance. Thevolatility of the LIHR controversy has highlightedboth a fascination and a seduction for new method-
ologies amongst surgeons and patients alike, whoappear to be equally pro-innovation. Most recentlythere has been a retreat from early heraldic predic-
tions, in the belief that LIHR is not a panacea forall hernias (Lawrence et al., 1995). The currentphase of development is centred upon the pro-duction of rigorous evidence, and the provision of a
more structured programme of training throughspecialist minimal access therapy training units(MATTUs).
Low molecular weight heparin and anti thrombolyticprophylaxis following elective orthopaedic surgery forhips and knees
Within elective orthopaedic surgery for knees andhips, there is a danger of post operative deep vein
thromboses (DVTs) which may on occasion lead tofatal pulmonary emboli (PEs). A number of preven-tive methods, including mechanical devices and a
number of anticoagulant drugs, have been con-sidered in dealing with this. However, the preven-tion of DVTs and PEs has to be weighed againstthe possible increased risk of wound haemotomas,
especially given that any subsequent infection posesmajor di�culties.
Clinical applications of chemical anticoagulantswere developed from the early 1970s, leading to anew generation of low molecular weight heparins
(LMWHs) marketed by drug ®rms by the 1980s.LMWH is a chemical agent which held out thepromise of much easier administration and fewer
haemorrhagic events, although they were more ex-pensive. It also remains an area of continuing scien-ti®c controversy and volatility, as there is dispute
that the current event rates in elective orthopaedicsurgery are of an order of magnitude lower thanthat which is generally quoted and that thereforethe potential bene®t of prophylaxis is small and
may not justify the risks (Chesterman and Chong,1993).This debate is driven exclusively by orthopaedic
surgeons, who represent a highly professionalised,distinctive, and resilient clinical community, despitethe macro level reorganisations apparent in the
NHS since 1990. Policy towards prophylaxis is nowbeing taken seriously with all groups adopting oneposition or another. However, this is a ®eld where
extensive and rapid change in clinical practice is evi-dent and the pattern of practice continues to evolvein volatile waves of change. There is still wide vari-ation in practice and the scienti®c controversy has
if anything reopened.
DISCUSSION
In this section, we discuss the four change initiat-
ives in relation to the heterogeneous framework ofpolitical power, professional knowledge, and agencyinterests, in which they are embedded. Our analysistraces the negotiations and alignments that emerge
among the di�erent stakeholder groups in each con-text. In so doing we highlight how these di�eringpositions inform, and are informed by, a complex
mix of scienti®c, organisational, and behaviouralfactors. We will show the connections within thosefactors where change was successfully achieved and
what Cartesian di�erentiations remained, where itwas not.
Connectivity and heterogeneity
By attending to the representational detail ofhow knowledge is produced, the duality separatingbiomedical research from clinical practice begins to
appear unsound. In rejecting such a duality bothextremes are collapsed: neither occupying a privi-leged position from which to judge the ``other''
dependent. The deconstructive writing of JacquesDerrida is an exemplar of such poststructural analy-sis. Derrida's thesis develops as a critique of
Cartesian di�erentiation and Hegelian idealism ±the primacy of the mind over the body ± in that itseeks the deconstruction of an emanative: di�erencefrom an external other, world of fully constituted
Martin Wood et al.1732
internal subjects and external objects. For Derrida,
nothing enjoys a presence in and of itself, but rather
carries the trace of its interweaving with a sup-
plementary ``other'' (Derrida, 1978).
According to Derrida the search to secure distinc-
tions between subjects/ objects, intellect/corporeal,
inside/outside, is as a result of an ontology of logo-
centrism. From the Greek, logos: to give order and
form to the world, logocentrism acts to legislate a
dominant source of reason (scienti®c research)
which serves to direct an external other (clinical
practice), and thus provide the illusion of mastery
over it. Derrida asserts that the root of this division
is the mistaken assumption of an existent source/
mode hierarchy. Derrida uses the invented word dif-
ferance ± embodying the irreducible use of the
French verb di�erer: to di�er, or disagree in space,
and defer: to adjourn in time ± to illustrate how
meaning cannot be grasped by constructing simple
inside/outside distinctions, but must always be situ-
ated within the interaction of a presence and its in-
ternal supplement. To locate meaning in di�erence
is to do so within things, part of which is present,
but part of which will always remain the property
of what it is not, what is present by being absent ±
deferred.
The impossibility of holding onto either/or dialec-
tics and analogical distinctions is also the nub of
Gilles Deleuze's materialist ontology. Rather than
dualist separation, he too suggests a more imma-
nent: internally di�erentiated, system of connection
and disconnection, in which the central issue is the
question of priority to body and mind (Hardt,
1993). Hegelian idealism explicitly places thought
outside (and over) being. Deleuze, following
Spinoza, alternatively contends that being is not
found in thought, and insists that we shift our focus
to recognise the importance of mind and body for
existence as a whole. In this way we can see how
the real distinction between research and practice is
in fact a relational di�erence founded on negation
(i.e. research is not practice). Deleuze eliminates the
negative aspect ``is not'', in favour of the notion of
a positive di�erence; an a�rmative di�erence, di�er-
ence in itself ± an internal di�erence.
According to Deleuze and Guattari (1988) this in-
ternal di�erence constitutes a whole made up of
lines of articulation: segmentation or strata which
give it a kind of disconnected objectivity, but also
counter lines of ¯ight, which set up movements of
destrati®cations, and which continuously rupture
and dismantle an object to produce a body without
organs. Hence, no once and for all determination
can ever be made about a body's interior strata,
only what it functions with, that with which it con-
nects. Change in this situation ceases to be connec-
tion between things ± there are no-things to become
± but is instead the vacillating interaction (Cooper,
1987) between ®xedness and movement within an
originary whole. Deleuze calls this internal inter-action becoming (Deleuze and Parnet, 1987).
Becoming denies both the ®xedness of being thatdualisms imply, and the simple interlocutionbetween two separate terms (e.g. research and prac-
tice). Instead, the two terms gather together in theelaboration of a third position, an indeterminateposition ``in'' and ``between'' both: never complete,
always becoming one or the other without everachieving totality. Deleuze o�ers the well knownencounter of a wasp and orchid as an example. He
argues that we cannot say once and for all thateach exists in parallel to the other, nor can we dis-tinguish where one ®nishes and the other starts.Instead Deleuze focuses on the extent to which the
orchid is a becoming-wasp and the wasp is abecoming-orchid (Deleuze and Parnet, 1987, p. 2):
The orchid seems to form a wasp image, but in fact thereis a wasp-becoming of the orchid, an orchid becoming ofthe wasp, a double capture since ``what'' each becomeschanges no less than ``that which'' becomes. The waspbecomes part of the orchid's reproductive apparatus at thesame time as the orchid becomes the sexual organ of thewasp.
The relation between ®xedness and movement issimilar to that of Callon et al. (1986) and the con-cept of Law (1992) of the actor-network. At its
centre lies the attempt to build a symmetrical ±thatis simultaneous ± account which considers the pro-liferation of continual networks of natural, socialand technological resources, and their collective role
in framing identity. Actors ± natural, human andtechnical ± are seen as nothing other than orderede�ects, as transient moments of a network of het-
erogeneous interactions, where no a priori distinc-tion exists (Law, 1992). For Callon et al. there is nogiven order of things, nothing exists in and of itself.
Instead, identity is continually performed by animmanent system of heterogeneous, social, textual,and material relations. Its puri®catory appearance
is not an originary presence, rather a meaningmade, brought into being and actually dependentupon the continual production and reproduction ofthe networks of heterogeneous interactions that
frame it. This is as much as to say that there mayindeed be privileged places, hierarchies and asym-metrical dualities, but that they are the outcome of
action, not its beginning (Latour, 1987).
A problem of (dis)connection?
Taken together, these approaches have importantimplications for the generation and implementationof biomedical research. Through such theorising it
is di�cult to accept the privileged claims ofresearchers as being somehow external to, and soindependent of, its counter position, practice, with-
out necessarily questioning the usefulness and val-idity of the research itself. Hence we are left withthe question of deciding where the generation ofresearch ends and its implementation begins.
Clinical behaviour change 1733
Following this lead, commentators such as
Brown and Dugiud (1991), Lave and Wenger(1991), and Star and Griesemer (1989), havesuggested that the local situation in which a prac-
titioner operates appears to be a potent mediator ofeveryday experience. It follows, therefore, thatresearch is rarely, if ever, self-evident to the prac-
titioner, but varies according to the context withinwhich it is received. Contextualisation is the conse-
quence of a particular organisation of thought andday-to-day experience. To contextualise is to supplya hitherto indeterminate body without organs
(research evidence), with organs (a practical appli-cation). It facilitates the creation of a relativelystabilised, but precariously balanced determination
of research by relating it to an already establishedand locally embodied structure for thinking andacting. Such ``situated knowledges'' (Lave and
Wenger, 1991) supply local regularities whichenable purposeful action by rendering remote and
obdurate evidence more acceptable and amenableto control (Chia, 1997). That is to say, theymomentarily ``arrest'' (Chia, 1997), or at least slow
down, the perpetual movement of becoming.Our empirical research has found broad support
for the idea that health professionals do not simplyapply abstract, disembodied scienti®c research,about which they have only scant knowledge of the
context or circumstance of its production, rigidly tothe situation around them. Whilst they may notnecessarily deny the researched phenomena, they
collaborate in discussion and engage in work prac-tices which actively interpret and (re)construct itslocal validity and usefulness (Brown and Dugiud,
1991). According to Knights (1997) it is not expertsrepresenting problems at a distance that are needed,
but practitioners actively participating in producingcontext related and localised responses to a set ofpolitical, economic, and social conditions with
which they are confronted.In other words, practitioners do not rely simply
on the implementation of disembodied, global the-
ory. They are not fooled by ``god tricks'' promisingvision from everywhere and nowhere (Haraway,
1991), but want to see the connections betweenwhat is advocated and their own situated knowl-edges. They look for a locatable position, a view
from somewhere (Haraway, 1991). This pragmaticperspective suggests that clinical practice containsmany judgements, much tinkering, reckoning, and
tacit knowledge, more reminiscent of craft skillsthan traditional conceptions of disinterested, com-
munistic and universal science (Ravetz, 1971). So,in promoting an innovation or piece of research evi-dence we are not dealing with the uncomplicated
dissemination of ®ndings to a largely passive andreceptive audience ± a simple problem of ``puttingtheory into practice'' in the hackneyed sense of the
phrase ± but with the question of reconnectingresearch with its supplementary other: practice. The
key point here is how evidence is translated (Callon,1986; Latour, 1987, 1993) within the assumptive
world of practitioners.
Reconnection: from implementation to translation?
The question of reconnection is the focus ofBruno Latour's anthropological analysis of modern-
ism (Latour, 1993). For Latour, the apparent sepa-rateness of politics, science, technology, and natureare as a result of the modern scienti®c method's
reluctance to mix nature and society.Modernisation: revolution in science, rupture fromthe past, and the birth of liberalism, made it poss-ible to distinguish between and administer par-
titions in which everything is assigned to onecategory or another. However, the proliferation ofquasi-objects: hybrid systems and problems that
consistently mix politics, science, technology, andnature, make it increasingly di�cult to maintaintraditional nature/culture distinctions. Latour
suggests we should rethink our constitution oftranscendent things and begin to recognise theirimmanent connectivity. He argues that the ``mod-erns'' posed an, unnecessary, ontological asymmetry
between puri®cation: the de®nition and implemen-tation of entirely distinct partitions and frames ±objects or people or techniques; nature or society or
technology ± on the one hand, and translation: thecreation and proliferation of continual links andnetworks ± objects and people and techniques;
nature and society and technology ± on the other.The proliferation of quasi-objects clearly demon-
strates that the developmental path followed by a
given innovation is neither natural or inevitable,but constantly negotiated and aligned ± a pathforged within an assemblage of scienti®c and organ-isational and behavioural factors. First, the quantity
and quality of local inter-relationships are factors inthis process. In settings where good interpersonalrelationships exist there is greater opportunity for
modalities of practice to be discussed and a com-mon way forward found. Where this was the case,our evidence suggests practitioners would be better
able to respond to information and decide tochange practice, or not, on the basis of it. In cases3 and 4, surgeons were far more likely to listen tothe views of others whom they thought were im-
portant and who in turn thought their own point ofview was important. Similarly, in case 2, good re-lationships built up over time between the medical
sta� and midwives, and the respect each group hadfor the others judgement, had led to a degree oftrust and independence for midwives which would
not exist everywhere.Second, the strength of any pro-change move-
ment is also a�ected by the ability to enrol a range
of product leaders. Such advocates can bring localcredibility to a project. They can help establish ameasure of agreement among professional groups,and use their position to make an initiative di�cult
Martin Wood et al.1734
to refuse. This pattern is illustrated in case 4, for
example, by the complaints from pro LMWHresearchers operating outside the orthopaedic com-munity about their inability to feed the results from
research through into practice; in the tacit experi-ence and problematic reproduction of laparoscopictechniques in case 3; and by the variable strength
and commitments of di�erent stakeholder groups ±obstetric/midwifery/patient ± to changing childbirth
protocols in case 2. Indeed, whilst respondentsspoke of the importance of grounding their practicein sound, scienti®c evidence, many acknowledged
that only exceptionally did research evidence alonechange practice. This pattern is found in the longand well organised process of consultation found in
the Changing Childbirth document (Department ofHealth, 1993), described in case 2, in which thepublished targets were clearly supported by a wide
and respected constituency of representatives of allthe key stakeholder groups, making outright and
public disagreement more di�cult. Thus, stake-holders were enrolled by virtue of it being costly, interms of reputation, credibility, medico-legal threat,
to not do so.Each of the initiatives studied is also broadly in
line with wider policy (for example: day case andde-medicalisation). However, it appears that localclinician ``buy in'' is essential if the policy is not to
remain abstract and under used. Professionals,therefore, still have a key role to play as changechampions, ``actioning'' national policy. Key aca-
demic researchers are particularly important here,quite often providing the ``hub'' of particularknowledge communities, from which innovations
and research themes radiate out into service depart-ments. In this way professionals provide the link
between, for example, an instance where the widerevidence calls for a change in practice and the needfor that change being recognised in a particular
knowledge or professional community. This point isrecognised in the recent government white paper,The New NHS: Modern, Dependable (Cmnd 3807,
1997), in which individual health professionals willcontinue to be responsible for their own clinical
practice.Those seeking to be legitimated as a universal
spokesperson for a research problem, cannot do so
without taking account of the locally-situated prac-tices that inform and are informed by it. Evidencecannot be put into practice because it was never
external to it in the ®rst place. Following Derrida,such a position implies the deconstruction of an
existent source/supplement hierarchy between thevisible ``body'' of evidence and the always invisiblenetwork of interactions supporting its appearance.
This suggests that research evidence cannot betaken to be a discrete and ®xed entity: a transparentexplanation of an existent clinical world and its mo-
tivating mechanisms. Instead, its apparent discre-tion and ®xedness is a result of the momentary
slowing down or arresting (Chia, 1997) of an essen-tially indeterminate process of becoming.
Evidence is important, but not that important!
The generation and implementation of biomedicalresearch has traditionally been theorised as depen-dent upon the delineation of set boundaries ± strat-
egy, R&D, policy, management, service delivery ±leading to the achievement of preconceived goals.But these distinctions are more implied than real,
and may be more productively conceived as a pro-visional presence/supplement determination.Our research suggests that scienti®c evidence is
not a clear, accepted and bounded source. There is
no such entity as ``the body of evidence''. There aresimply (more or less competing) (re)constructions ofevidence able to support almost any position. Much
of what is called evidence is, in fact, a contesteddomain, constituted in the debates and controver-sies of opposing viewpoints in search of ever more
compelling arguments. This is apparent if one con-siders the apparent unity of the evidence for antic-oagulation described in case 1. The unanimity hereis dependent upon, and not the cause of, the contin-
ued taking of the INR as a standard baselinemeasure; in the lasting association of certain medi-cal conditions and an increased risk of stroke; in
the predictability of the decision support system.Our ®ndings suggest that an identical process
underscores all bodies of evidence, no matter how
``hard'' and monolithic their appearance. This pos-ition is not necessarily divisive, however, but couldbe interpreted as demonstrating a more pluralistic
attitude towards clinical practice. Looking at thingsfrom di�erent perspectives is not intrinsically wrongand indeed may be an inevitability in a modernhealth care system. In any event, it underscores our
contention that evidence cannot be viewed as a rela-tively neutral ``medium'' for expressing the natureof reality, but exists only as a stabilised moment in
an indeterminate process of becoming.Evidence from trials and published material in
prestigious journals may be in¯uential in setting
indirect climates of opinion, yet they rarely changepractice on their own. This may be explained by thefact that the evidence base often fails to capture thetacit and experiential nature of practice. For
example, in talking about the Changing Childbirthdocument (Department of Health, 1993) and why itshould or should not be implemented, few respon-
dents used evidence as their main argument. Whereit suited individuals, they ignored the evidence orthey did not appear to know about it. Moreover,
whilst some aspects of an evidence base can beframed to appear much clearer, stronger and lessrefutable than others, this situation is always (more
or less) precarious ± the extreme limit of the slow-ing down of movement (Chia, 1997). This meansthat one requires precision in talking about ``evi-dence'', i.e. evidence on what speci®cally?
Clinical behaviour change 1735
The outreach modality of anticoagulation service
delivery in case 1 is an exemplar of an initiative
with a strong evidence base, but which remains
severely limited in its development. Why should this
be? The study was described as both a ``top-down''
regional initiative, together with the ``bottom-up'',
local activities of an interested clinician. However,
di�erentiating between notions of top/bottom and
regional/local may be of limited utility, as both
appear to rely on the other for their meaning.
Consequently, initiatives may require an internally
di�erentiated relationship of tolerance from the
``top'' and buy in from the ``bottom'' for success
(for example, the Changing Childbirth (Department
of Health, 1993) initiative is top down but clinicians
acting in a speci®c situation may choose to buy in,
opt out, betray or divert the initiative).
Likewise, surgical specialisms are exemplars of
highly individualistic practices. Practitioners exhibit
a high level of embodied skill, yet seldom, if ever,
simply disregard the scienti®c basis of their practice.
This was rarely presented as a choice: experience or
science, but as an awareness of the need to balance
both. For example, despite its strongly contested
evidence base and the fact that LIHR has not
replaced more traditionally based procedures in
case 3, it has, nevertheless, had a signi®cant impact
on surgeons' attitudes, in terms of a re-opening of
debate and forcing re¯ection on the e�cacy of long
standing practices. So, we can say that even with a
strong evidence base, an initiative's development is
not likely to be natural or inevitable, but complex
and long term, and will not be achieved without the
involvement of interested practitioners.
Attitudes towards EBM were also found to be
typically varied, although generally speaking, they
can be characterised as follows. First, it is seen as a
mechanism for delivering real improvements in
practice. Second, EBM is simply a jargon phrase,
popularised in order to give a name to what had
always been there. A third characterisation drew
attention to a wider political agenda lying behind
its advocacy, whilst a fourth highlighted the fact
that practices existed for which there was no evi-
dence base available. Fundamentally the question is
whether there can ever be a perfectly explicit and
transparent evidence base. From our research, the
answer is no. However, EBM appears to represent
and has come to be representative of just such a
logocentric view of evidence as a dominant source
of scienti®c reason which serves to direct an exter-
nalised clinical practice and thus provide the illu-
sion of a source/supplement hierarchy. As we have
seen, however, this view is erroneous and partial, in
that it fails to re¯ect the aspect of evidence which is
constructed in situ. As it is currently perceived,
EBM is spuriously premised solely on a unilinear
model of information gathering and dissemination.
As such, it fails to recognise the shifting, contextual
and intractable reality of knowledge (re)construc-tion.
The parergon
We have seen how Derrida and Deleuze bothadopt a poststructural episteme that does not oper-ate around subject/object distinctions. And, how
they refuse to reduce anything to a unitary pre-sence, but rather argue for indeterminate assem-blages of connection and disconnection. Instead of
either/or determinations, we ®nd only a folding ofrelative ®xedness and movement and of a presenceand its (always present by being deferred) sup-plement. But, what do we see when we pay atten-
tion to this fold?In The Truth in Painting, Derrida (1987) is con-
cerned to show that jurisdiction over the truth is
not so much an essential presence, as a kind ofmeaning made, brought into being and actuallydependent upon that which frames it. The concept
of the frame (parergon) acts just like the lens of acamera, or the stage in a theatre, it delineatesbetween what is inside and what should remain out-side: which pole of a binary opposition is privileged
and which will remain supplementary. The framecan give rise to a judgement, or determination; anarresting of the indeterminate edge (aÁ-bord),
between the work (ergon) and the absence of work± the distinctive either/or characteristic of dialecticthought.
Derrida, however, considers what is incompre-hensible about the frame (par-ergon: literally, by thework) of a painting, is its indeterminateness as a
surface which separates itself not only from thebody proper of the work, but also from the wall onwhich the painting is hung. The frame stands outfrom both the work and the background, but it also
connects the one to the other. For Derrida, thisabsence, or lack of presence, cannot be situatedinside or outside of the work, but remains a compo-
site of outside and inside. The whole frame isneither internal or external. It does not fall, unilat-erally, on one side (outside) of the work, but is
gathered together as the supplement of an internalindetermination of the work it comes to frame:``No `theory' no `practice', no `theoretical practice'can intervene e�ectively in this ®eld if it does not
weigh up and bear on the frame'', maintainsDerrida (1987, p. 61). The frame is the ``decisivestructure'' in determining what is internal, seen, and
what is excluded, unseenThis is particularly apparent in the surgical cases
3 and 4, where not only was there no challenge to
the issue being seen as a clinical dominion, but alsoone in which other, allied professional groupsenjoyed only limited in¯uence. Thus, following
Derrida, we can see how certain dissonant voicesare being excluded (Fox, 1997). The ability tosecure distinctions between included/excluded voicesappears to be as a result of the production and
Martin Wood et al.1736
structuring (framing) of (usually unequal) logo-
centric power relations. Similarly, in case 2 juridicalissues have been historically enduring since the sec-ond part of the 19th century, when obstetrics was
established as a surgical speciality, and care inchildbirth shifted to the hospital setting. This shiftled to a growth in the role of the doctor and the
use of technology and was concomitant with themarginalisation of the role of the midwife.
In case 1, however, whilst the service is framed inthe sense that it is super®cially possible to deter-mine what it is from what it is not, its e�ectiveness
remains indeterminate. For example, to be e�ectivethe service has to satisfy the many, variant andloosely coupled practices and idiosyncrasies of
many burdened hospital clinicians, the ephemeral,(often) fragmented and frequently indecipherable
written inscriptions which (sometimes) followpatients between GPs, hospital, and laboratory, aswell as compensating for and replacing the de-
®ciencies in public transport, failing bodies andarduous clinic visits. No one framing has estab-lished itself as the truth: it has not been possible to
make an e�ective/ine�ective determination. Its e�ec-tiveness remains an internal indetermination of the
service, a composite of the demands and practicesof several partially connected (Strathern, 1991)voices.
Moreover, the historical juridical delineation incase 2, between the highly medicalised, hospitalbased interventions of obstetricians and the more
tacit based care o�ered by midwives, has nowbecome one of the critical determining variables in
the changes proposed. It is still unclear whether theopening of the old frame will result in a consider-able shift in the historical role and professional
responsibilities for care from obstetricians to mid-wives. What is clear, however, is that the hithertoreal inside/outside distinction between obstetrics
and midwifery has been displaced by the fact that itis only an apparent closure of an internal presence/supplement relationship after all. What might
hitherto have been seen as an existent inside/outsidehierarchy between two separate, disconnected voices,
can now be seen as the internal indetermination ofwhose voice should be heard. The framing of thediscussion can be seen as the necessary connection
within the interaction of a presence and its internalsupplement.
Hence, as we move towards a ``shared care''regime in the U.K. NHS, perhaps we should resistthe monolithic appearance of many traditional
inside/outside frames that insist we do not mixresearch and practice. We should stop dealing withresearch and practice as uncontaminated, uni®ed
things in themselves and begin to recognise theincreasing incidence of indeterminate, mixed-upa�airs. Thus, in our exegesis of clinical behaviour
change, we might expect to concentrate on edgesand interfaces: on ¯ows across boundaries and not
the integrity of logocentric divisions. Practitionersneed to move away from ambitions of hierarchical
stability and ontological purity, and instead becomeopen to the indeterminate ¯ux and transformationof becoming.
IN-CONCLUSION
Drawing on the poststructural theme of indeter-minate becoming, this paper has highlighted the
need to shift away from notions that research evi-dence and clinical practice are diametricallyopposed. It has moved towards models that engagethe complex and dynamic network of interactions
supporting the appearance of a phenomenon (Chia,1997). A key feature of our case studies has beenthe extent of boundary indetermination ± science/
practice; universal/local; presence/absence ± as apart of the change process. Di�erentiating betweenresearch and practice is of limited utility, as in our
®ndings the boundary between driver and driven isalways indeterminate: there is a practice-becomingof research at the same time as there is a research-
becoming of practice. Within this model, prac-titioners are not passive, but in¯uence the uptakeand must be engaged.Furthermore, whilst evidence is often discussed as
if it constituted a clear and distinct entity, our ®nd-ings suggest this is erroneous. The nature of evi-dence is ambivalent. It is constructed into debates
and controversies, which are often equally suppor-tive of opposing viewpoints. Such issues appearrecursive and intractable not linear and incremental,
so that a ®nal resolution remains unlikely in manycases. The ``progress'' of science serves only towiden the debate. Here, the ability of EBM to
become the perfect analogue of the complexity ofpractice is in doubt, as its current methodology isnot readily amenable to accessing the tacit andexperiential knowledge of practitioners. Hence, it
seems likely that its implementation will be complexand long term, and may achieve only patchy suc-cess.
In conclusion, there is a need for those involvedin a�ecting clinical behaviour change to movebeyond unilinear models of information gathering
and dissemination, and towards research strategiesthat address the local ideas, practices, and attitudesof professionals. A key function here will be toengage the interest and involvement of practitioners
in future change programmes by (re)connecting evi-dence with its supplementary ``other''. In movingfrom an over reliance on simple production±disse-
mination models of change, there is a need to incor-porate evidence and practice in a more immanentrelationship and perhaps to recognise that this has
always been so.
