What is involved in a clinical trial: time commitment and costs

The length of trials can vary from 1 day to 3 and more years, so some make greater demands than others. The demands of the trial and the practical implications, such as travelling, time off school and work, holidays, and money, were things some parents considered.

Several people described ways staff made it easier for people to take part, such as flexible days and times for appointments, organising parking, combining research appointments with routine hospital visits, or research staff offering home visits. At some clinics, having toys, TV, books and games for children to play with whilst waiting for appointments helped make participation easier.

Having the option to have the vaccine injections at the weekend made it much easier for Josie and…

Ann and her daughter Emily are taking part in a randomised trial to improve treatment for Grave’s disease (a rare condition in young girls that affects the thyroid glands). Emily must take tablets every day as part of the trial and attends the hospital regularly to be monitored. They will be in the trial for four years. Ann says it has been hard, but she doesn’t mind the extra demands of the trial because it is helping her daughter and other young girls who may be diagnosed with Grave’s disease in the future.

Ann and her daughter sometimes have to leave early in the morning to attend hospital appointments…

However, after 2 years Alison decided to withdraw her son from the trial. (See also ‘Withdrawing your child from a trial’.)

Alison had to weigh up the demands of the trial with the demands of family life and work and…

None of the parents we talked to enrolled their children in a trial that involved a payment for taking part. Some parents would have been concerned if money had been offered as an incentive for taking part. Some felt it would be unethical or would attract people for the wrong reasons. One parent said she would have found it insulting and would have refused to enrol her son if a payment had been offered. There was a feeling that being paid to take part might lead people to think there was a substantial risk involved and this would have made parents more cautious about enrolling their child.

Alison felt that offering a payment may change peoples attitude to taking part in trials, but if…

Sometimes children received a voucher as a way of saying thank you for taking part. Parents felt that this was a nice gesture although no one felt it would or should be a reason for taking part, and in fact it was usually a surprise.
