risks of applying decoupling by ICT. For both
scenarios a suggestion is made how to repair
possible negative effects on other communication
features.
3.2 Scenario 1: e-Consult
The electronic consult or e-Consult can be regarded
as an additional way of communicating between a
patient and his physician alongside the regular face-
to-face consultation. By decoupling on time/place
context the patient can ask questions that were not
addressed during the normal consultation or ask for
extra explanation or details for treatment, while the
general practitioner can reply to patient questions
outside the hectic office-hours.
Despite of these advantages, the e-Consult is still
offered by a minority of primary care doctors.
Literature (van Gemert, 2006) shows that for most
general practitioners the disadvantages of
introducing the e-Consult clearly outrange the
advantages (see table 1).
General practitioners mainly regard the e-
Consult as a replacement for the consult by
telephone and not as a contribution to a better
quality of healthcare. This will probably be the
reason that one of the main negative effects of
decoupling on time/place context - i.e. the lack of
personal contact – is mentioned only after arguments
regarding higher workload and incompatibility with
the information system. A closer look at the effects
of decoupling gives support to the opinion that an e-
Consult is a replacement for a consult by telephone
rather than a substitute for a regular face-to-face
consult.
Table 1: Advantages and disadvantages of using the e-
Consult (questionnaire filled in by 654 Dutch general
practitioners).
Advantages Disadvantages
Meeting the patients wishes Higher workload
Outside office hours No reduction of regular
consultations
Reduction of number of
consults by telephone
No financial compensation
Incompatibility with the
Information system
Lack of personal contact
Decoupling on time-place context directly has
effect on other features of the communication
process and in particular the message exchange
component. Compared to the face-to-face consult,
the interactivity will decrease, the structure of the
content will increase, the capacity of the medium
(i.e. the number of supported modalities) will
decrease and the evanescence will become low.
Because modifications of features such as
interactivity and capacity - that are essential for a
regular consult – cannot be repaired, an e-Consult
will never be a good replacement for a regular
consult. A related consequence is that the use of e-
Consults is only limited to non-urgent
communication and between actors already having
an established patient-doctor relation.
3.3 Scenario 2: Clinical Research based
on Clinical Patient Data
In scenario 1, decoupling on time/place context only
effects a number of features of the message
exchange component, but the context of domain (i.e.
the clinical care setting) remains the same. In this
scenario 2, we will look at decoupling on time/place
context accompanied by a changing context of
domain (i.e. from clinical care to clinical research).
The clinical researcher wants to reuse the clinical
patient data that were captured by the clinician
within the context of patient care. Reuse of data that
were registered for another purpose is only feasible
when a number of preconditions are met. Let us first
assume that the cognitive distance between the
researcher and the clinician will be limited when
they are working within the same field. But their
needs with respect to the granularity of the data and
the number of parameters will diverge. The most
important precondition however is that sufficient
context information is available to the researcher to
determine whether the data meets the requirements
for research. As a first step towards semantic
interoperability the clinician should use controlled
terminologies during the registration of his findings.
But apart from using non-ambiguous codes for
findings or diagnoses the correct interpretation is
always dependent on (part of) the original context
that usually gets lost by the decoupling process (e.g.
reasons for visit, medication history, co morbidity).
Therefore a prerequisite to make reuse of clinical
data possible is an electronic patient record system
facilitating capturing and communicating both the
data and their context.
4 DISCUSSION
Transformation of a communication scenario as
described in the introduction to a communication
scenario supported by ICT may imply that both the
clinical data and their original context are available
to all authorized users any time and any place. It
may also imply that additional measures must be
