a. Reminder note to the health care professional Appendix
D. b.
Advice slip to patients were also distributed. c.

4.3 Phase III
4.1.1 Post Intervention data
In the end of May which is five months after intervention was implemented, the first post intervention blood pressure
measurement was collected and this continue monthly for next three consecutive months June to August 2007. Also collected are
age and sex. Each month 300 samples were taken for each group. In total, there are four sets of post intervention data comprising blood
pressure, age and sex in both intervention and control groups which designated as Post 1 May, Post 2 June, Post 3 July and
Post 4 August.
The Table 5 showed the results of blood pressure outcomes, age and sex within intervention group from May till August before and
after.
From the Table 5, we could see that the improvement in number of patients whom their blood pressure treated to target in post
intervention 1 intervention group was very significant when compared with pre intervention. In the control group difference
between pre intervention and post intervention 1 was not significant. In the following month, the improvement was not
significant but just sustaining. However in post intervention 3, there was a drop in the percentage of patients in intervention group
