OP-268 : Effectiveness of Designated Treatment Partners among

Rojim Sorrosa, Philippines
The study seeks to determine the effectiveness of designated treatment partners selected according to a doctor and a patient’s preference in controlling the haemoglobin A1c levels (HbA1c) at values lesser than or equal to 6.5% among non-insulin treated diabetic patients.

The study is an open-labelled randomized controlled trial which enrolled 60 patients from January to June 2009 at the Family Medicine Clinic of the Philippine General Hospital. The treatment partners were randomized to two groups namely, the doctor’s preference and the patient’s preference group. The primary outcome measure was targeted towards controlling HbA1c levels at values equal or less than 6.5% with a 0.6% difference between arms.

The baseline socio-demographic and clinical characteristics were similar except for the duration of diabetes (p=0.04) and baseline systolic blood pressure (p=0.04). The mean scores for burden of illness, health perception, and perceived adherence factors were similar for both arms. The mean HbA1c scores for both groups were similar at baseline (8.41 v 7.89, p=0.43). Results showed that the HbA1c levels for both groups were lower than the cut-off value of 6.5% after sixth-months of follow-up, these differences were not statistically significant (p=0.28). Majority of the chosen partners in both treatment arms are their spouses. Marital adjustment and high levels of perceived intimacy could have facilitated a healthy adaptation to diabetes hence, achieving the target HbA1c levels across arms.

Selection of designated treatment partners according to a doctor’s preference is unlikely to be effective over treatment partners selected according to a patient’s preference.
