2 RESEARCH APPROACH 
We applied a qualitative methodology to investigate 
our research question. We conducted a multiple case 
study using two out-patient histories in Norway from 
September-October 2013. Case study is defined as 
“scholarly inquiry that investigates a contemporary 
phenomenon within its real-life context (Yin, 
1994).” Multiple case study is instrumental study  
which allows researchers to understand and analyse 
several cases across settings thus leading better 
theorising (Stake, 2005; Baxter and Jack, 2008).  
Data was collected through conducting 
document analysis, observations and interviews at a 
surgical out-patient clinic in a hospital in Norway. 
Due to ethical consideration, a chief nurse explained 
two patients’ histories by showing the electronic 
documents in an EHR system and other relevant 
paper documents; no direct access to the EHR 
system was given to the researcher. Semi-structured 
interviews with the chief nurse followed after the 
nurse’s explanations. To obtain deeper insight in the 
histories, we conducted observations and 
unstructured interviews of a secretary working at the 
hospital’s post/document centre, a medical doctor 
(specialist) and a health secretary working at the 
clinic. During the observations, the researcher took 
notes and some photos of the documents were taken. 
All interviews were audio-recorded. Email 
exchanges and telephone conversations 
supplemented the data after the interviews. 
Document analysis is a systematic method for 
reviewing or evaluating documents, which is 
unobtrusive and nonreactive when obtaining 
empirical data (Bowen, 2009). Observation is a 
useful data gathering method in naturally occurring 
settings and it helps the researchers to understand 
the users’ context, tasks, and goals (Rogers et al., 
2011). Unstructured and semi structured interviews 
can be most suitable when the researchers want to 
have a deeper insight of a problem domain that is 
not familiar by giving the participants the chance to 
educate the researchers. (Lazar et al., 2010). 
Interviews and/or observation are often used to 
establish credibility and minimise bias of the data 
from document analysis, as a means of triangulation 
(Bowen, 2009). Triangulation is a process of using 
several sources of evidence to clarify meaning and 
verify the repeatability of an interpretation (Stake, 
2005). 
We analysed the collected data of two out-patient 
histories using qualitative content analysis 
(Graneheim and Lundman, 2004). Thematic analysis 
(Fereday and Muir-Cochrane, 2006) was used to 
fine-tune the analysis.  
3  INSIGHT OF THE PATIENT 
HISTORIES 
In this section, we introduce the patient histories and 
explain how we analysed our data. First, we briefly 
describe the two out-patient histories. Second, we 
present the process of our analysis.  
3.1 The Out-patient Histories 
The first patient history covered a period of ten and 
a half months. Different places were involved in this 
case, including a GP centre and two hospitals. 
Several stakeholders were involved: a patient, GP, 
secretary, radiologist, minimum two specialists, 
health secretaries, and nurses from the hospitals. 
Three different health information systems were 
used: a GP’s EHR system, a radiology information 
system (RIS), and a hospital EHR system. These 
systems were used to store and share the patient 
related information. The GP’s EHR system and the 
RIS could communicate with the hospital EHR 
system in a limited degree (e.g., sending and 
receiving electronic referrals or results of computed 
tomography (CT)).  
The second patient history covered a period of 
two and a half months until the time of the interview 
and was still ongoing. Different places were 
involved in this case, including a GP centre and 
three hospitals. Even more stokeholds were 
involved: a patient, GP, radiologist, two 
pathologists, minimum three specialists, secretaries, 
health secretaries, and nurses from the different 
hospitals. Four different health information systems 
were used: a GP’s EHR system, a RIS, and two 
different types of hospital EHR systems. The GP’s 
EHR system and the RIS could communicate with a 
hospital EHR system in a limited degree, like in the 
first case. However, the other hospital EHR system 
could not communicate with the three other systems 
at all. Therefore, more interactions with physical 
evidence, such as a postal letter, were generated to 
cover the communication barrier (e.g., a specialist 
received a referral via postal letter).  
Figure 1 shows the communications between the 
stakeholders in the first out-patient case and

information systems in the first out-patient case.
