| Abstract | BACKGROUND: Quality adjusted life years (QALYs), based on health related quality of life (HRQL), are a commonly used concept in health economics. The aim of this study was to apply the concept of QALY to the evaluation of a surveillance program for health related effects of PCB exposure and measure the impact of occupational PCB-exposure on the remaining QALYs of participants. METHODS: The internal PCB exposure was determined by gas chromatography with mass spectrometry in plasma. The HRQOL was assessed via the EQ-5D-3L instrument and combined with the remaining lifetime (RLE) at the time point of cessation of exposure. For comparative reasons we used both the linear calculation and the complex-number-model from Prieto and Sacristan. The impact of several PCB congeners was regressed on the percentage of discounted QALYs on RLE via hierarchical multiple regression, controlling for gender, relational and educational status. RESULTS: Findings were able to detect a small but significant effect of elevated plasma levels of PCB on QALY for the linear calculation and partially for the complex number calculation. This means that an internal exposure to PCB reduced HRQOL in the RLE of participants in the surveillance program. CONCLUSION: QALYs can be applied successfully to monitor HRQL effects in surveillance programs. The exposure to a hazardous substance has an influence on QALYs. Findings have to be interpreted as a first hint. In the following assessment it has to be monitored whether there is an improvement or worsening of HRQL. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
