reported that they had a clear understanding of the instructions and also geriatric patients
found that they frequently did not understand how to time their dosing in relation to meals.

In a multisite study of primary care patients, nearly half were unable to understand one or
more of the label instructions on ive common prescription medicines.

However, most studies on patient’s understanding about prescribed
medications are taken from Western developed countries, while there is a relative lack of research
from developing Asian countries especially in Indonesia.
Clear communication performed while giving the medicine to the patients consists of
giving written and oral information,
8-10
which if seen from the patients’ perspectives are the
tools to help their understanding. However, how important the role of each of the information
toward patient understanding is still unknown. This research aims to evaluate the impact of
written and oral medicine information toward patient understanding regarding the received
medicine information with the hope to in- crease adherence and medication safety.
2. RESEARCH FRAMEWORK AND
HYPOTHESIS
H1: Written medicine information patient given has a positive effect on patient understanding.
H2: Written medicine information given has a positive effect on oral medicine Information
given. H3: Oral medicine information given has a
positive effect on patient understanding. H4: Oral medicine information given mediates
a relationship between written medicine information given and patient understanding.
3. METHODS
3.1 Unit Analysis
The unit analysis is primary health centre.
3.2 Sample
The research caters for 200 respondents of 120 toddler’s caregivers who their toddlers
are receiving medicines prescriptions as well as 80 elderly patients who are also obtaining
medicine prescriptions from doctors. Respondents came from 40 health centres of which had
been selected randomly out of the total 62 in Surabaya. Respondents from every primary
health centre were three toddler’s caregivers and two elderly patients, which were randomly
selected.
3.3 Data Collection
The written data information was taken from the observation toward the embedded
medicine label accepted by respondents and matched with its label photos. Likewise, the oral
data information was obtained while the patients were receiving medicines and its explanation
from pharmacy staff. The respondent under- standing data was taken from the structured
interview result after the respondents had received their medicines. Data was collected from May
to August 2014.
3.4 Data Analysis
The obtained data is analysed descrip- tively using Pareto principles, stating that:
“ around 80 of all positive results
are produced by just 20 of efforts. Similarly, roughly 80 of all problems
can be traced to approximately 20 all possible causes”, cited from Sashkin,
11
Rinehart,
12
and Robson.
13
Approximately, 80 performance is the result of 20 effort, hand in hand with
around 80 problems can be traced through its 20 factors. Based on Pareto Principles
this means the research variable indicator of good quality gains the score 4 and 5, higher
than 80, while the less qualiied indicator gaining score percentage of 4 and 5, lower
than 80 requires serious attention in particular if the percentage score 4 and 5 is smaller than
20. This means there is a 80 performance problems or more and we need to learn its cause
by checking the percentage which possesses scores 1, and 2 as much as ≥20. Correlating
the condition, Sallis

states that:

“This suggest that 20 of the processes cause 80 of the problems”.
with the test will be held on mediation effect of oral medicine information on giving
written medicine information towards patient understanding with PLS SEM v 3.0.
