3.3.6 Method six: Focus groups with practice nurses
Focus group interviews with practice nurses formed the sixth and final method in
the study, and were used to explore current practice, and the potential structure,
process and content of an ‘ideal’ pre-travel consultation. They provided a useful
form of triangulation to test the validity of findings from other methods, and to
provide a rationale and shape of a prototype for the new model of consultation.
Focus groups have been defined as “…an interaction between one or more
researchers and more than one respondent for the purpose of collecting research data” (Parahoo, 1997:296).
This method was chosen to gather data because it offered the following
advantages:
• Focus groups are a recognised method in health care research, particularly for
exploring health promoting beliefs and activities (Parahoo, 1997);
• There is an opportunity to use group dynamics and interactions to generate
more ideas and perspectives than might be achieved through individual
interviews (May, 1997; Sim and Wright, 2000);
• They are a forum to test the validity of findings from other methods; a useful
form of triangulation (Adami and Kiger, 2005);
• An assessment can be made of the degree to which health professionals
support, oppose or contribute to a proposed new model of pre-travel health
consultation (Sim and Wright, 2000);
• Focus groups can be a cost-effective way to gather data (Parahoo, 1997).
Sampling and recruitment
A minimum of 20 and maximum of 30 participants were sought for method six.
Five focus groups of between two and six practice nurses were achieved, with a
total of 23 participants. This represented non-probability, purposive sampling,
because the aim was not to represent the whole practice nurse population evenly
and equally, and participants were selected according to criteria – the nurses had
to engage in travel health care and work in general practices that had not
participated in the audit of structures and AV recordings of consultations.
Potential participants were identified through general practice addresses available
in the public domain. PCT and practice details, including whether travel health
services were provided, were available via the Internet. Only those practices within
PCTs who had given ethical permission, and who had not provided participants for
sheets (Appendix 2) were sent to 35 nurses in 20 general practices. A response
rate of 66 per cent was achieved: six declined, one did not attend, five could not
make any of the dates offered, and 23 participants completed the focus group
interviews.
Despite a non-probability sample, the 23 practice nurses worked in a variety of
general practices, from one single-handed GP practice to those with partnerships
of eight, ranging from rural branch surgeries, suburban premises, to inner city
practices. They had a range of experience within practice nursing of between six
months and over 20 years, and none were newly qualified. Although information
about age was not specifically collected or required for this study, the participants
appeared congruent with statistics that 46 per cent of practice nurses are over the
age of 45 (RCN, 2009b). A pre-paid envelope was provided for replies, and the
nurses accepting participation were then contacted to arrange the date and venue
most convenient for them.
Tools and piloting
The process of developing a discussion schedule was similar to that of the
interview schedule used for travellers – the topics to be discussed were distilled
from the literature on consultations and travel health, and from the findings and
themes from previous methods in this study. They are detailed below under Data
collection and analysis, and a discussion tool about consultation styles is found in
Appendix 10. The role of the researcher was different from other methods, and in
the literature is variously called a moderator or a facilitator rather than an
interviewer, reflecting the different processes to be managed in focus group
The discussion schedule was piloted with a group of four nurses who were not
included in the final study. This permitted familiarisation with the recording
equipment, playback and transcription process, and to check on timing. The pilot
transcript was used to assess the researcher’s techniques as discussion facilitator
and appropriateness of the discussion topics. Techniques used with groups, e.g.
ensuring every participant’s views are heard, or the use of probe questions, were
already familiar to the researcher, but the pilot provided an opportunity to check
and reflect on these, and to ask for objective feedback from group members. No
major changes were required.
Data collection and analysis
The five focus groups were held in September 2008. An Olympus DS50 digital
voice recorder with multi-directional microphone was selected because of its silent
and discreet operation, and software compatibility with Windows programmes for
playback and transcription. The process was to welcome and introduce
participants, establish ground rules and rapport, facilitate the discussion using a
semi-structured schedule, and to close proceedings. The full schedule is shown in
Appendix 9.
The recordings were stored according to data protection requirements, and
transcripts created to organise data for analysis. Silverman’s (2001) adapted
transcription technique, as used for AV consultation recordings and interviews with
travellers, was employed (Appendix 3). Consideration was given to coding using
qualitative data analysis software, and introductory training was undertaken on an
NVivo programme. This offered potential advantages such as auditing the
analytical process, and to a degree, checks on reliability and validity. The
analysis was started ‘by hand’. This proved to be advantageous because thorough
familiarity with the data was gained, enabling interrogation of a small sample in
greater depth and accuracy than was achieved through an NVivo pilot.
The content was first analysed by each of the eight topics to make explicit the full
range of responses to each topic. Data were then searched and categorised by
themes identified in previous methods. These were analysed for congruence with,
or dissonance from those themes. Finally, the contents were searched for any
new concepts or themes not found in previous methods. Analysis was undertaken
using the researcher’s interpretation of text to allocate it to coding categories and
themes. Computerised colour coding and cutting and pasting of text facilitated this
stage. Secondly, computer keyword search functions were used to check all text
had been found and appropriately categorised within a topic, code or theme. The
findings are presented in Chapter 5, Phase Two: What do practice nurses say and
do?
