WEB-BASED SPATIO TEMPORAL SURVEILLANCE SYSTEM OF TB IN KHYBER PAKHTUNKHWA

Abstract

This research was based on the TB Risk Analysis based on Union Council (UC) level of the three districts, Peshawar, Charsadda and Mardan of Khyber Pakhtunkhwa (KP). The TB risk factors; Case Notification Ratio (CnR), Population, Old Age People data, Poverty Incidence and Literacy Ratio were consider for the years 2007 - 2010. The performance of TB Diagnostic Centers (DCs) data was used with each DC hinterland to assess its performance. A web-based application was developed to make the results available on the web to facilitate managers and other stack holders for better monitoring, supervision and decision making. All the risk factors of TB were calculated and then assigned to the respective UCs. Each risk factor was given equal weight to participate in the final result. The DCs performance were determined by considering the performance indicators, Case Detection Rate (CDR), Cure Rate (CR), Treatment Success Rate (TR) and Default Rate (DR). CDR was given the maximum weight of 50 while CR and TR receive 20 each and 10 to DR. The results show that the district of Charsadda has the highest No. of UCs in the High Risk class followed by the district Mardan. Most of the DCs are struggling for good performance while the DCs with good performance are very few. In the year 2010, the high risk areas were found lesser in number than of the previous years while in the same year the DCs performance has also been improved. The identification of the risk areas on UC level will help the NTP and other agencies in controlling TB by prioritizing the High Risk areas and will help them to intervene there. The web based application will enhance the monitoring and supervision of the TB control programme.
