Abstract: Satisfaction is the level of one's feelings after comparing the performance or results they feel with
expectations. Importance Performance Analysis (IPA) method and Customer Satisfaction Index (CSI) is one
of the methods used to determine the level of conformance between performance and expectations. In this
study IPA and CSI methods were used to determine the level of patient satisfaction in one hospital in Sumatra
Utara with a sample of 83 respondents. Data collection methods using questionnaires and conducting
interviews directly with respondents. The method used to measure the quality of service is applied
SERVQUAL method with five dimensions of service characteristics namely, physical evidence, reliability,
responsiveness, assurance and awareness. The results of data analysis applied IPA method that there are four
service attributes that must be repaired by the hospital because the quality of service is still considered low
but its performance is considered very important by the patient. The results of data analysis applied the CSI
method indicate that the level of patient satisfaction with the quality of care at the hospital is 0,82, this is
included in the category of very satisfied.
1 INTRODUCTION
Health is a state of well-being from the body, soul and
social that allows productive life socially and
economically. In this sense health must be seen as a
whole which consists of physical, mental and social
elements (UU No.23, 1992 tentang kesehatan).
Health is one of the basic human needs. Therefore,
choosing a health service provider or hospital is
something that must be done in order to get good
health services from the hospital.
The hospital is the spearhead of development and
public health services, but not all hospitals in
Indonesia have the same standard of service and
quality. The increasing number of hospitals in
Indonesia and the higher public demand for quality
and affordable health facilities, the hospital must
strive to compete in the midst of increasingly fierce
competition while meeting these demands. It became
one of the foundations for hospitals to provide
excellent service to every type of service provided.
Understanding the needs and desires of patients is
an important thing that affects patient satisfaction.
Satisfied patients are a very valuable asset because if
patients feel satisfied they will continue to use their
chosen services, but if patients feel dissatisfied they
will tell others twice about their bad experiences.
The variables studied were Emergency Room,
Doctor, Nurse, Medical Facility, Food and drink,
comfort and cleanliness, administration and finance,
as well as information and registration. this
percentage is said to be good in accordance with the
measurement aspect set by Indonesian Ministry of
Health. The measurement aspect for inpatient services
is said to be good if the percentage of patient patient
satisfaction is greater than 80%
2 LITERATURE REVIEW
2.1 Importance Performance Analysis
Method
This technique was first put forward by Martilla and
James in 1977 in their article "Importance-
Performance Analysis" published in the Journal of
Marketing. In this technique, respondents are asked to
assess the level of importance and performance of the
company, then the average value of the level of

importance and performance is analyzed in the
Importance-Performance Matrix, where the x axis
represents perception while the y axis represents
hope. In pursuance of Supranto (2006:41) The level
of suitability is the result of a comparison of the
performance performance score with a score of
importance. This level of suitability will determine
the priority order of increasing factors that affect
customer satisfaction. The formula used is:

(1)
Where:
= Score the average level of attribute
performance assessment to-
= The average score of the level of importance
assessment of attributes to-
= Number of respondents
Then to calculate the average level of importance
and performance of the overall attributes using the
formula

(2)
Where:
= Performance average value of all questions
= Performance average value of all questions
= Number of question attributes
Then the results will be obtained in the form of
four quadrants according to the Figure 1.

Where:
A. First Quadrant (top priority) shows factors or
attributes that are considered to affect
customer satisfaction, including elements of
services that are considered very important,
but management has not implemented it
according to customer wishes. Considered
very important and unsatisfactory;
B. Second Quadrant (maintain achievement)
shows the essential service elements that have
been successfully carried out by the company,
for which it must be maintained. Considered
very important and very satisfying.
C. Third quadrant (low priority) shows some of
the less important factors for the customer, its
implementation by the average company.
Considered less important and less satisfying.
D. The last quadrant (exaggerated) shows the
factors that influence customers is less
important, but the implementation is
excessive. Considered less important but very
satisfying.
2.2 Customer Satisfaction Index (CSI)
Method
CSI is used to analyze the overall level of service user
satisfaction by looking at the expected level of
product / service attributes. CSI value in this study is
divided into five criteria according to the use of Likert
assessment. Point 5 of the level is very unsatisfactory
to very satisfying.
Irawan (2004), measurement of CSI is needed
because the results of the measurement can be used as
a reference to determine targets in the coming years.
CSI can be calculated with the following stages
1. Determine Mean Important Score (MIS) and
Mean Satisfaction Score (MSS). This value is
based on the level of importance and
performance of each respondent.

3 DISCUSSION
In this paper there were 83 respondents who were
used as samples to analyze the level of patient service
satisfaction in one hospital in Sumatra Utara.

3.3 Analysis of Performance Interest
Level with Importance
Performance Analysis (IPA)
Method
The IPA method is used to measure the relationship
between consumer perceptions and priority of
product / service quality improvement, which is also

known as quadrant analysis. Quadrant analysis which
is divided into four quadrants covering the first
quadrant top priority, second quadrant maintain
achievement, third quadrant low priority and
excessive quadrant.
The quadrant IPA mapping can be seen in the
Figure 2.

3.4 Satisfaction Level Analysis with the
Method of Customer Satisfaction
Index (CSI)
Measuring the level of patient satisfaction in this
study uses the CSI method. To see the results of the

The results of the analysis applied CSI of 83
respondents the level of patient satisfaction with the
services provided by the hospital was 0,8198 so that
it was rounded to 0,82. This shows that the quality of
service in the hospital is categorized as very satisfied.
In this study identified that patients in the hospital
were very satisfied with the services provided by the
hospital.
4 CONCLUSIONS
Based on data analysis so that it can be taken
conclusion from research result, based on the level of
importance it can be seen that the most important
thing is that the doctor has the ability and knowledge
to determine the diagnosis of the disease properly
while the lowest level of importance according to the
patient is that the hospital has a fairly comfortable
waiting room and the hospital has clear directions and
instructions. Based on quadrant analysis applied IPA
method, the factors that are in the first quadrant are
factors that are considered important and expected by
consumers, but the performance of the producers has
not given satisfaction to what consumers expect
optimally, so make consumers feel disappointed. This
dimension needs to be prioritized for improvement.
By applied CSI method, the level of patient
satisfaction with the services provided by the hospital
was 0,82 indicating that the patients in the hospital
were very satisfied with the services provided by the
hospital.
