| description | <p>Significant debate exists about the utility of blood glucose self-monitoring
(BGSM) in patients with non-insulin treated type 2 diabetes. Previous studies
lacked any theoretically based intervention and produced conflicting results.
The novel randomized controlled trial reported in this thesis used a
theoretically based intervention to evaluate the effectiveness of BGSM as a
strategy of glycaemic feedback to promote self management. </p>
<p>Psychological theory was used to develop an intervention to support use of
glycaemic feedback to promote self-management. Measures based on similar
psychological theory were also developed to assess the effectiveness of the
intervention in targeting the hypothesized mediators of behaviour. Participants
were randomized to one of three intervention arms: regular HbA<sub>1c</sub>, BGSM with
facilitator interpretation and BGSM with patient interpretation and application. </p>
<p>There was no significant difference in HbA<sub>1c</sub> between the three groups after
one year (p=0.653), although significant reductions were noted in all groups
in patients with HbA<sub>1c</sub> over 8%. There were no significant differences in
secondary clinical outcomes of change in weight (p=0.649) or systolic or
diastolic blood pressure (p=0.890 and p=0.860 respectively). Significant
changes in beliefs and behaviour were limited to change in illness coherence
(p=0.041) and in eating high fat diets (p=0.009) and five portions of fruit and
vegetables daily (p=0.017). </p>
<p>Semi-structured qualitative interviews were used to explore patients'
experiences and perceptions of BGSM. Participants who had difficulty in
adhering to self-management recommendations found BGSM helpful,
whereas those who had previously followed recommendations were
discouraged by BGSM results if they did not reflect their efforts. </p>
<p>BGSM with patient interpretation and application did not significantly improve
HbA<sub>1c</sub> or other clinical parameters when compared to BGSM with facilitator
feedback or regular HbA<sub>1c</sub> measurement. It also had little effect on illness
beliefs and self-reported behaviour. It did, however, appear to be beneficial in
patients who had difficulty in following self-management recommendations. </p> |
