Knowledge and perception of off-label drug use amongst prescribing physicians in a tertiary care hospital.

INTRODUCTION

Off-label drug use is commonly reported in various disciplines of medicine. Considering the lacunae of studies from prescribers in the Indian subcontinent, the present study was conducted to explore their awareness and views of off-label drug use.

METHODS

A validated questionnaire was administered to interns, junior residents and faculty members who were recruited in the present study of various medical and surgical departments of Subharti Medical College, Meerut, India, a tertiary care teaching hospital. Descriptive statistics was used for analyzing the data.

RESULTS

A total of 59/85 (69%) stated that they have used a drug in an off-label manner mainly [31/85 (36.5%)] related to indications. Nearly half of the study participants (41/85, 48.2%) considered prescribing an off-label drug illegal and only 25/85 (29.3%) participants felt that they had adequate knowledge regarding the use of drugs in off-label manner. Out of the total 70 participants who answered the question related to informing parents/relatives while prescribing an off label drug, only 39/70 (55.7%) answered affirmative. Out of the remaining 31/70 (44.3%) of participants who did not inform about prescribing an off label drug, 9/31 (29%) felt that it was illegal and more than two-third (24/31, 77%) felt their knowledge on off-label drug use was insufficient. Surprisingly, 74/82 (90.2%) participants felt that a drug approved to be used in adults cannot be used in children for the same indication despite not having any alternative in pediatric age group.

CONCLUSION

We found an inadequate knowledge regarding the off-label drug use amongst the prescribers in a tertiary care medical college hospital. Many of the physicians felt such use as illegal and do not inform the patient's relatives about such acts. Considering the legal issues, clearly there exists a need to patch up this lacuna in developing countries like India.
