Knowledge, attitude and perception survey of doctors regarding antibiotic use and resistance in Karachi, Pakistan

Objective: To establish a better understanding of physicians' knowledge and beliefs, and to compare distinctions in knowledge, attitude and perception of junior and senior doctors regarding rational use of antibiotics. Methods: The cross-sectional study was conducted at a tertiary care hospital in Karachi, from June 1 to July 31, 2016, and comprised senior and junior doctors. A 26-item questionnaire divided in three sections was used to test knowledge, attitude and perception of the subjects regarding rational use of antibiotics. Data was analysed using SPSS 23. Results: Of the 200 subjects, 132(66%) were senior doctors; 68(34%) were junior; 116(58%) were females; 84(42%) were males; and the highest number of respondents were from General Medicine 65(32.5%). While 182(91%) doctors realised that antibiotic resistance was a pressing issue, only 131(65.5%) felt confident about their prescriptions and 94(47%) admitted that they over-prescribed antibiotics. Among young physicians, 13(19.1%) believed that antibiotics did not cause side effects even when prescribed unnecesarily. Also, 47(69.1%) junior doctors felt that patients' demands influenced their prescriptions compared to 66(50%) senior doctors (p=0.01). Conclusion: Although physicians were found to be knowledgeable about rational use of antibiotics, there were gaps in knowledge and perception.
