Obstetric emergencies are the leading causes of maternal mortality worldwide and particularly in developing countries. The Auxiliary Nurse Midwife (ANM) is the key field level functionary who interacts directly with the community and has a great role in assessing and preventing obstetric emergencies. Keeping in view, a pre-experimental research study was carried out in Auxiliary Nurse Midwife Training Centre (ANMTC), Berhampur, Ganjam, Odisha with the objectives to assess the effectiveness of an information booklet regarding selected obstetric emergencies and their management among ANM students and to find out the association between pre-test knowledge score of ANM students with their selected demographic variables. Data were collected from 60 ANM students by simple random sampling technique using a structured questionnaire. The overall mean knowledge score in the pre-test was (13.83 ± 2.24), which is 34.57% revealing poor knowledge, whereas in the post-test it was (30.08 ± 3.95), which is 75.2%, revealing good knowledge and effectiveness was 40.63%. Highly significant (P < 0.01) difference was found between pre and post-tests knowledge scores and no significant association was found between post-test Knowledge scores with all their selected demographic variables.
