2. Aims
30-10-2015 2
understand in more detail similarities and differences
between clinicians’ and patients’ perceptions
regarding the treatment for T2DM
Research questions
• How do patients and clinicians perceive the need for treatments that manage
challenges beyond hyperglycemia, including obesity, lipids, hypertension, … ?
• How perceive clinicians and patients meaningful weight loss?
• How perceive clinicians and patients weight management as a motivator to patient
self-management?
• How to characterize the disconnect between patients and clinicians regarding the
above?
3. Methods
30-10-2015 3
online survey
10 minute structured online questionnaire
across 13 countries
stepwise design:
- originally drafted by HCP focussing on the main objectives
- developed by an iterative Delphi type approach
- mirrored questions for clinicians and PWD (“people with diabetes”)
- reviewed by international T2DM experts
- reviewed by clinicians from external steering committee
- piloted by some PWDs
- tested in small number of PWD from English speaking country
4. Methods
30-10-2015 4
After pilot testing
- data reviewed to ensure good understanding of scripts
2nd pilot of PWD questionnaire
- as further check for language, length, flow and clarity
Final survey
- translated in local languages
- back-translated in English
to confirm language and face validity
5. Methods
30-10-2015 5
Data collection
- baseline demographics
- mix of question types
- 4 and 5 point semantic (Likert) scales
- frequency counts of 1st, 2nd or 3rd ranks
- pre-coded / dichotomous questions
Analysis
primarily conducted to show percentage distributions of ranks
across the samples as applicable at a global/country level
6. Participants
30-10-2015 6
Clinicians
identified in response of answers to questions about the healthcare
they provided and the medical conditions they treated
People with T2DM (PWD)
recruited from
- online communities
- social media
- affiliated partners
- web-based sources
selected their condition from a list of different conditions without
being informed about qualifying condition for the survey

26. Discussion
30-10-2015 26
Limitations:
• statistical comparison of differences is not possible
• similar versus identical questions
• inclusion of T1DM could not be ruled out
• conclusions on causality are not possible
• respondents drawn from online surveys
• respondents seem to be more educated than average
• sensitivity analyses confirmed valid survey results
• country level differences most likely based on:
• demographics
• availability of medicines
• standards of care
27. Conclusions
30-10-2015 27
• differences between perceptions of HCP and PWD regarding
T2DM disease management
• for HCP managing weight is most challenging, not so for PWD
• less concerned for modifiable risk factors
• unaware of relationship with long-term complications
• HCP overestimate PWD’s anxiety with self injection
• HCP underestimate PWD’s concerns about adherence
• more than half PWD consider only weight loss > 10 % as
meaningful and stresses on short-term goals
• Ineffective communication perhaps contribute in these
differences of perceptions
Need for further education and better communication
