A comparative study of knowledge, attitude, and practice of drug-drug interactions among interns and nurses in a tertiary care hospital

ABSTRACT

Background: Increasing use of drugs has led to drug-drug interactions (DDIs) which necessitate their awareness among the health-care providers to reduce the hospital admissions due to their adverse drug reactions. Aim and Objectives: This study aims to assess and compare the knowledge, attitude, and practice (KAP) of DDIs among interns and nurses and to evaluate the impact of an educational program with a pre-and post-test questionnaire. Materials and Methods: An educational program about DDIs was conducted for the interns and nurses to evaluate their KAP by a pre-test and post-test pre-verified 20-point questionnaire about DDI. Results: There was a statistical significant difference (P < 0.05) in gender (females Males = 7716) among the interns and nurses and their mean age was 23 ± 0.87 years and 21.3 ± 0.83 years, respectively. Both the groups fared well in post-test compared to pre-test in the knowledge (questions=7), attitude (questions=5), and practice (questions=8) domain which was statistically significant. On comparing the post-test scores, both the groups showed no difference statistically (P > 0.05) in the knowledge and attitude domain, while the nurses group showed more improved mean score than interns in terms of practice of DDI. Conclusion: The educational program about DDIs was effective among the interns and nurses with regard to their KAP assessment and they equally performed well. This implies that the awareness program about DDIs was successful among the interns and nurses who form the lower strata in delivering the health-care needs to the society.
