The effect of cost information on patient outcomes: a randomised controlled trial

Study hypothesis
1. When patients are made aware of the financial cost of a given healthcare intervention they will be more satisfied with their care, and the treatment will have a greater positive impact on their well-being
2. The higher that the patient believes the cost of the treatment is, the greater the satisfaction and well-being derived from the intervention will be
3. The provision of cost information will also have an effect on clinical outcome (price/placebo effect)

Intervention
The trial will involve randomisation of patients to three groups. Initially all participants complete the measures, as well as providing information regarding how much they think the treatment will cost. Information will then be given to participants depending on their randomisation.
1. Group one will have no information regarding the cost of treatment, simply information regarding the procedure
2. Group two will receive the information regarding the cost of the surgery according to the standardised NHS national tariff, as well as the procedure information
3. Group three will receive the cost of the information specific to the study site, which is a considerably higher cost, as well as the procedure information
