Brief summary

This was a randomized control trial carried out in the primary care clinic in University Malaya Medical Centre, Malaysia.

Interventions

A graph measured 12 x 13cm with 7 points on the y- axis and 6 points on the x- axis was printed on a ivory white card measured 21cmx24cm. The graph was divided horizontally into green, yellow, red and black area, represented good, can be improved, high and too high HbA1c level respectively. The card was covered with a blue colour paper printed with title “HbA1c Card” and the researcher name plus the phone number. The HbA1c result was plotted on the graph at the corresponding follow up duration

A graph measured 12 x 13cm with 7 points on the y- axis and 6 points on the x- axis was printed on a ivory white card measured 21cmx24cm. The graph was divided horizontally into green, yellow, red and black area, represented good, can be improved, high and too high HbA1c level respectively. The card was covered with a blue colour paper printed with title “HbA1c Card” and the researcher name plus the phone number. The HbA1c result was plotted on the graph at the corresponding follow up duration (x-axis) and trend were exhibited by drawing a line between the results. The patient in the HbA1c recording graph group will received the card at the recruitment day. They will keep the card and bring it during the follow up day. The researcher will update the HbA1c reading on the card on each visit . A standardized explanation on the HbA1c result was given to each participant(e.g. the HbA1c result is normal or high and the HbA1c result had improved or worsen) The patient will be seen at 3- month and 6-month. So the total duration of follow up was 6 months. At the end of the study, the patient will keep the card.
