In cases of emergencies, school teachers are expected to play a key role in performing basic life support (BLS) on school children. Very limited data are present in the literature that address the knowledge of the schoolteacher regarding BLS. The primary objective of this study was to asses the BLS knowledge, training status and attitude towards pediatric BLS among schoolteachers. The study had a cross-sectional research design and was conducted between January and March 2017. A self administered questionnaire was used for data collection to assess the knowledge of teachers. The questionnaires were filled in by 541 teachers (243 male and 298 women). The median age of the study population was 39 (34-45) years. One-third of the respondents reported having taken a BLS class in the past (33.1%). The mean for the correct answers for the study population was 5/14 (4/14-7/14). For trained teachers, it was 6/14 (4/14-8/14) and for untrained teachers, it was 5/14 (3/14-7/14)(P < 0.001). There were no differences between teachers who had attended different BLS courses. Significant differences between teachers were observed: 62% of teachers with previous BLS training felt capable of providing cardio pulmonary resusitation (CPR) to their students compared to 48% in the group without previous training (P =0.001). Ninety-five percent of the teachers were eager to attend a BLS course and 92% reported that BLS training should be mandatorily given for teacher certification. Teachers are aware of the importance of BLS and they are willing to attend BLS training programs and improve their knowledge. Despite the fact that the knowledge of trained teachers was found to be better than those of untrained teachers, school teachers in Turkey have a low level of knowledge and skills regarding BLS.
