Background and Aims
In light of the new NICE Type 1 diabetes
(T1DM) guidelines1, we wished to
explore current practice in the choice of
insulin regimens for adults with newly
diagnosed T1DM amongst healthcare
professionals (HCPs) in the UK and
Ireland, to identify if there is consensus
about what should be used as well as
the factors that influence clinicians’
choice of regimen.
Methods
An on-line questionnaire using Survey
Monkey®2 and incorporating ‘skip logic’
to enable respondents to bypass
irrelevant questions was developed and
piloted within our own services before
being distributed via ABCD, DAFNE,
DMEG and Diabetes Education Network
emailing lists.
The survey was live for 1 month
(October 2015).
Data collected included:
• Profession
• Main area of practice
• Clinic post code
• Availability (plus name) of structured
education programme
• Factors influencing choice of regimen
(ranked 1-8)
• Types of insulin used (human vs
analogue)
• Choice of regimen on day 1 for a
patient newly diagnosed with T1DM
• Reasons for choosing alternative
regimen for newly diagnosed
• When regimen are changed if
necessary
• When patients are offered structured
education
Conclusion
There is variation in choice of insulin regimen, perhaps reflecting a dearth of research data
from this patient group. HCPs should be encouraged to audit and publish data on their
newly diagnosed T1DM patients.
92 (41%) ranked ‘evidence’ as the
primary influencing factor for choice of
insulin regimen; with ‘personal
experience’ and ‘protocol’ being ranked
second and third respectively.
Amongst those ranking evidence first,
the treatment of choice for newly
diagnosed is an analogue-based MDI
regimen using once-daily basal (50%
doctors; 45% DSNs; 48% dietitians).

Results
227 surveys were
completed
Respondents
• 34% doctors
• 38% DSNs
• 26% dietitians
• 2% unspecified.
Area of Practice
• 78% worked in
NHS secondary
care
• 18% in NHS
primary care
• 4% non-NHS.
113 individually listed cities, towns or
regions were represented, from
Shetland in the North of Scotland to
Taunton in the South of England;
Galway in the West of Ireland to
Yarmouth in the East of England.
Incomplete postcode data prevented
linkage of data from the same clinics.

Structured Education: Complex
Starting Regimen
96% (n=107) of those using analogue-
based multiple dose injection (MDI) with
once-daily basal insulin offered
structured education. 45% (n=50)
specified DAFNE
100% (n=34) of those routinely using
analogue-based MDI with twice-daily
basal insulin (as recommended by NICE)
offered structured education. 97% (n=33)
specified DAFNE
Simple Starting Regimen
Twice-daily NPH or once-daily analogue
basal were preferred by 21 (9%)
respondents (11 and 10 respectively).
Structured education was offered in all of
these services.

Insulins Used in T1DM By Those
Stating ‘Evidence’ as the Primary
Influencing Factor
Summary
227 HCPs (34% doctors) responded,
78% in NHS secondary care. Whilst over
80% use some form of MDI regimen for
newly diagnosed Type 1s and 40% state
that evidence influences their prescribing
decision, only 15% choose NICE-
recommended analogue-based MDI
using twice-daily basal. There is no
obvious relationship between the initial
insulin regimen and the availability of
structured education in the results of this
survey
