Aims
To evaluate the (cost‐)effectiveness of Beyond Good Intentions (
BGI
), a 12‐week group‐based, nurse‐led self‐management programme, in terms of cardiovascular risk factors, self‐management and quality of life, after 2.5 years of follow‐up in pre‐selected individuals with known Type 2 diabetes of up to 5 years’ duration.
Methods
A parallel randomized controlled trial comparing
BGI
with usual care, based on a self‐management screening questionnaire, was conducted in 43 general practices after pre‐selection of participants. After 2.5 years of follow‐up, the between‐group changes in the abovementioned variables were assessed using analysis of covariance.
Results
A total of 108 participants (
BGI
group,
n =
56; control group,
n =
52) were included. Changes over time in
BMI
(–0.4 vs –0.5 kg/m
2
) were similar in the two groups. Median HbA
1c
[
BGI
group 47 mmol/mol (6.5%); control group: 49 mmol/mol (6.6%)] and mean systolic blood pressure (
BGI
group: 132±13 mmHg; control group: 133±14 mmHg) were well controlled at baseline and no intervention effect was found.
LDL
cholesterol levels decreased from 2.4 to 2.2 mmol/l in the control group and remained stable at 2.6 mmol/l in the intervention group (
P
=0.032). No intervention effect was found for self‐management or quality of life.
Conclusion
In contrast to the first
BGI
study, we did not observe significant effects of the
BGI
intervention, despite pre‐selection of individuals. In diabetes populations with target levels for HbA
1c
, systolic blood pressure and
LDL
cholesterol, no further beneficial effects can be expected from self‐management programmes with regard to biomedical factors and quality of life.
