maintaining high immunization coverage is an 
important step in controlling cases of measles[3]. It 
means that CBMS and measles immunization should 
work together to reach the elimination target. In our 
study we found the coverage of first-dose 
immunization measured in three years was 95%, 
which exceeds the UCI target, but the average of 
measles booster coverage in the last three years was 
60%, which is inadequate. Another research showed 
that although the coverage of single-dose measles 
immunization was high enough, still it was not 
sufficient to give population protection to prevent the 
outbreak of measles[2].
 
This epidemiologic 
description is similar to the situation in Yogyakarta, 
where the first dose immunization coverage 
surpassed target coverage and was exceptionally 
high, but measurable incidents were still prevalent in 
the region. 
Quality health services should reflect 6 
dimensions based on WHO guidelines, which include 
effective, efficient, accessible, acceptable, equitable, 
and safe services[13].
 
In this study we found the main 
dimensions of effective, efficient and accessible 
services were present in the study sites. The quality 
delivery of CBMS was still inadequate in response 
time when the outbreak was happening, while the 
timeliness of monthly report delivered, and 
cooperation with private practice such as doctors or 
midwives to find the cases were also lacking. While 
the quality of measles immunization program 
services was inadequate or ineffective in timeliness of 
monthly report delivered, refresh knowledge from 
DHO annually, and coverage of immunization of 
measles booster were also lacking. In order to 
improve the overall quality of health services, all 
aspects should be considered holistically covering the 
organization, team, and health staff individually[13]. 
They already have a good fidelity by adhere the SOPs 
in routine and outbreak cases, but they still need to 
improve the performance of response time to have 
good quality delivery of CBMS.  
The key for the success of surveillance systems 
involves not only being integrated with measles 
immunization programs[2], but also it should be 
integrated with training human resources, improving 
the data analysis, monitoring the impact of 
intervention, informing health policy design, 
planning and program management, and 
strengthening laboratory capacity, with emphasis on 
community participation in detection and appropriate 
response to public health problems[14]. 
5 CONCLUSIONS 
Case based measles surveillance was implemented to 
detect, prevent and control the measles disease. 
District health offices of Yogyakarta already have 
made an alert to detect the outbreak, and conducted 
rapid response to give an intervention. However, a 
number of gaps still remain. These include inadequate 
human resources to perform data analysis, and a lack 
of coordination to meet the challenges. Although the 
coverage of first dose immunization can be seen as 
high but the second dose immunization did not meet 
the target and there were still many outbreaks in 
Yogyakarta. To properly respond to the outbreaks, the 
level of knowledge of immunization officers 
associated with the measles elimination program 
should be enhanced, as well as synchronization of 
programs between CBMS and measles immunization, 
so that the goal of elimination of measles in 2020 can 
be achieved. 
  One of the limitations of this study, is that the 
assessment is only seen from the perspective of health 
workers. The results would be strengthened if this 
research included observations and the points of view 
of the patients.  
ACKNOWLEDGEMENTS 
Thank you to the Provincial Health Office and 
District Health Office of Yogyakarta City, which has 
given me permission to carried out our study at 
Primary Health Center of Yogyakarta City. I would 
like to thank Kihariadi for his guidance and assistance 
in data collection and analysis for our study.
