CRUZ MARTINEZ, Óscar Andrés  and  MUNOZ SANCHEZ, Alba Idaly. Validation of instrument to identify the vulnerability level of health workers to tuberculosis in health institutions (IVTS TB-001). Med. segur. trab. [online]. 2015, vol.61, n.241, pp.448-467. ISSN 1989-7790.

Health and Safety at work is a priority for health care workers, given their permanent exposure to hazardous agents in the process of work. In particular, exposure to TB in health care workers is considered a common and important problem to be studied, which, in turn, requires the need to develop methodological processes and validation of robust tools that contribute to the identification and intervention vulnerabilities of health workers in the tuberculosis sector. Objective: To design and validate a tool to identify the level of vulnerability of Health Workers TB in health facilities. Materials and Methods: methodological, design and validation of an instrument validation phases apparent and content validation, to identify the vulnerability level of Health Workers TB in health institutions. Results: made the design of the instrument, in its 4 dimensions, 19 subdomains and 50 items, with subsequent validation apparent in the target population, by assessing the comprehensibility, in a random sample of No. = (502) health workers, two institutions in which care is offered to patients diagnosed with tuberculosis. The assessment of the instrument comprehensibility in the target population was (97.8%). Similarly, in the judgment of experts a higher rate of > 0.58 in understanding the items with N = (0.90), accuracy N = (0.90), and clarity of the N = (0.92) was obtained. In the content validation a reasonable Lawshe validity, amended by Tristan N = (0.91), was met, demonstrating the characteristics of face and content validity instrument. Conclusion: The design and validation of the instrument (IVTS TB-001) at the level of validation apparent understanding of the items obtained in the study population. Also, results obtained in assessing face validity of understanding, accuracy, clarity, and content validity in the relevance of the items given by experts, which makes it a very useful tool in the field of Health and Safety at Work in the health sector, which enables the identification of the level of health vulnerability workers in regards to tuberculosis in health institutions and the evaluation of the vulnerabilities of Health Workers to tuberculosis.
