Background:
In Indonesia, the highest leading cause of death is due to cardiovascular disease (37%). In Gunungkidul, top five highest number of disease are dominated by NCDs such as hypertension, diabetes, and injury. NCD surveillance system in Gunungkidul district has not been evaluated externally. This study was to evaluate the NCD surveillance system for future improvements.

Methods:
This was a descriptive study adopting CDC Updated Guidelines for Evaluating Public Health Surveillance system. Evaluation item consist of description of surveillance system: operation the surveillance system, resource used to operate the system, and performance of the surveillance system (system attribute). Participants were one officer of District Health Office (DHO) and 30 officers of Primary Health Centers (PHC). Data was collected using standard questionnaire and observational checklist.

Results:
Operation surveillance system showed that they used an integrated NCD surveillance form. Collected data was the number of new cases. We found that there was a difference in interpreting operational definition (OD) of new cases. New cases should be a patient with new diagnosis of NCD during a visit to PHC. In fact, was about 20% PHC officers input the old cases as new cases when the first visit after the turn of the year. Private sector did not involve yet as source for system surveillance data collection. For resources, NCD surveillance guidelines were distributed only in 56% PHC. DHO and 57% PHC had limited funding to operate the system. For system attributes, completeness and timeliness were 73.9% and 65.5%.

Conclusion:
NCD surveillance system had problem in dissimilar operational definition in data collection. This operational definition difference distract NCD data quality. Intervention was given by conducting a meeting to disseminate evaluation result and build consensus about the operational definition of cases. We recommend DHO to improve cooperation with private sector.
