Consent for audio-video recording of informed consent process in rural South India

In recent times, audio-video (A-V) recording of consent process for all the study subjects entering a clinical trial has been made mandatory. A-V recording of informed consent process is a big challenge due to confidentiality and the sociocultural environment in India. It is important to find out the acceptability for A-V recording of the consent process and reasons for refusal, if any to address this new challenge. A descriptive survey was done among 150 residents of a rural community of South India. Acceptability for A-V recording of consent process was assessed among those who had given the informed written consent for participation in the study. An attempt to find the factors determining the refusal was also made. More than one-third (34%) of the study subjects refused to give consent for A-V recording of consent process. Not interested in recording or don't like to be recorded (39%) were the most common reasons to refuse for A-V recording of consent process. The refusal was higher among female and younger age-group adult subjects. Socioeconomic status was not found to be significantly associated with refusal to consent for A-V recording. Refusal for A-V recording of consent process is high in the South Indian rural population. Before any major clinical trial, particularly a field trial, an assessment of consent for A-V recording would be helpful in recruitment of study subjects.
