A study is to know the efficiency and effectiveness of the new family planning information system that has been socialized since 2007. To compare with the previous information system, this study was conducted in four provinces i.e., DKI Jakarta, Lampung, Central Kalimatan, and Bali. In each province two districts were randomly selected, and from each selected district two health centers were then randomly selected. Data was collected from June to September 2008. Results of this study revealed that the effectiveness and efficiency of the new family planning information system is considered good, where 77,8% of the respondents reported it as effective or more effective, and 66,7% stated more or much more efficient compared to the previous system. The mean score for effectiveness and efficiency vary between provinces (p-value <0,01). The lowest score was found in Bali (mean 68,9 for effectiveness and 61,3 for efficiency), and the highest score was in Central Kalimantan (mean 82.7 for effectiveness and 82.2 for efficiency). There is no significant difference of the score according to characteristics of the respondents. This study recommends to improve the family planning information system, especially by providing and implementing the local monitoring graph, in the health center and its network.
