بررسي سروكانورشن تست پوستي سل در پرسنل بيمارستان رازي قائم شهر در سال هاي 96 - 1394

Evaluation of Tuberculin Skin Test Seroconversion Among the Staff in Qaemshahr Razi Hospital, 2015-2017

سابقه و هدف: سل بيماري مسري است كه توسط باكتري مايكوباكتريوم توبركلوزيس ايجاد مي شود. نزديك به 30 درصد جمعيت جهان به عامل بيماري سل آلوده هستند كه در 10-5 درصد آن ها بيماري سل بروز مي كند. هدف از اين مطالعه بررسي سروكانورشن تست پوستي سل بوده است. مواد و روش ها: پژوهش حاضر مطالعه اي مقطعي بر روي 114 پرسنل بيمارستان رازي قائمشهر در سال هاي 96-1394 بود. ابزار جمع آوري اطلاعات پرسشنامه بود و نتايج تست پوستي سل ثبت شد. تجزيه و تحليل آماري داده ها توسط نرم افزار SPSS نسخه 20 صورت گرفت. استنتاج: پرسنل بيمارستاني به دليل تماس مستقيم با بيماران مبتلا به سل در ريسك عفونت با عامل بيماري سل مي باشند. از طرفي با توجه به سروكانورشن تست پوستي توبركولين، لازم است به طور ساليانه تحت غربالگري قرار گيرند. ايزولاسيون بيماران سل ريوي مورد توجه قرار گيرد و آموزش هاي لازم جهت پيشگيري از ايجاد عفونت براي پرسنل مدنظر قرار داده شود و وسايل حفاظت فردي براي كاركنان تهيه گردد.

Background and purpose: Tuberculosis is a contagious disease caused by mycobacterium tuberculosis. Approximately 30% of the world's population is infected, 5-10% of whom develop active tuberculosis. The aim of this study was to determine the tuberculin skin test conversion. Materials and methods: A cross-sectional study was conducted in 114 staff working in Qaemshahr Razi Hospital, 2015-2017. Demographic characteristics and the results of tuberculin skin test (TST) were recorded in a checklist. Data analysis was done in SPSS V20. Results: The participants included 15.8% males and 84.2% females (mean age: 29.42±5.03). Among the subjects, 33% had latent tuberculosis. TST was positive in 11.4% in first evaluation and 36.84% had positive TST in the second assessment. TST seroconversion was observed in 25.44%, in 61.4% the working experience was more than 10 years, and 61.5% worked in infectious department. There were significant associations between the positive result of TST and age, gender, and working experience (P=0.002, P=0.021, and P=0.01, respectively). We observed significant differences in the results of TST between the first and second evaluation (P<0.0001). Conclusion: Hospital staff are at high risk for developing tuberculosis due to direct contact with tuberculosis patients. Due to TST seroconversion they should be screened for TB annually. Isolation of patients with pulmonary tuberculosis and practical trainings should be considered in order to prevent infection in staff. Personal protective equipment is also needed for individuals working in hospitals.
