Effectiveness of motivational
interviewing in patients with
dyslipidemia treated in primary care
consultations: randomized controlled
trial by cluster (Dislip-EM study)
ICMI 2014 Amsterdam
Objective of the study
To verify the effectiveness of a multifactorial
intervention based on motivational intervention by
General Practitioners (GPs) trained in motivational
interviewing (MI), to improve the control of lipid
levels in patients with dyslipidemia, compared with
standard medical advice.
Multicenter, open, controlled and randomized
cluster, with two parallel arms formed by two
groups of population with a follow-up over 12
months in primary health care.
Study design
25 Primary Health Centers located in four regions of Spain.
Study site
• 227 adults aged 40 to 75 years with uncontrolled
dyslipidemia in situation of primary prevention of
cardiovascular disease, captured by their GPs with
consecutive sampling.
Study subjects
• 38 GPs were randomized to an intervention with their patients based on MI
or informative advice usual.
• MI was delivered in the Experimental Group (EG), and usual intervention in
the Control Group (CG).
• A specific training plan was designed and implemented in the EG.
• The fidelity of the MI intervention was checked with video recordings of
real consultations with a scale designed and validated in this study (EVEM
questionnaire).
• Follow-up: 1 year.
Intervention
Both Groups GPs:Explained guide clinical
performance in dyslipidemia and
training video recording
Workshop training MI 16h
Booster training: micropills, videorecording feedback with
expert…
No specific training in MI
EVEM questionnaire
Control Group
Intervention Group
Performance in GPs
• Main outcome measures :
• Reduction of lipid levels: total cholesterol, LDL-cholesterol,
Trglycerides.
• Other outcomes variables:
• Reduction of cardiovascular risk
• Degree of improvement in diet
• Increase of physical activity and weight loss in overweight
patients.
Determinations

Data analysisConclusions
TRAINING MI
• An intention to treat analysis has been conducted. To check the
effect of the intervention a comparison of means test (ANOVA,
Kruskal-Wallis) and proportions (Chi-square, McNemar) was used,
and a multivariate analysis was done. Using Multiple Linear
Regression or Logistic Regression (p ≤ 0.05).

Conclusions1. An approach based on Motivational Interviewing conducted by
primary care physicians aimed at improving the lipid profile in patients with dyslipidemia, has not proven to be more effective than usual intervention.
2. Both Motivational Interviewing and the usual care, significantly reduces total cholesterol, LDL cholesterol, triglycerides and cardiovascular risk after a one-year monitoring program.
3. Motivational Interviewing gets to make the patients increase their level of physical exercise to a greater degree than the usual approach.
4. Professionals who perform a motivational approach use less lipid-lowering drugs than the control group in patients with dyslipidemia.
