“…In summary, the population was mostly male, with a mean age of 70 years, with limited educational qualifications and with most retired from work. We were unable to assess whether those recruited by multimedia differed in characteristics from those who were recruited using conventional methods [16]. Such analyses are not routinely done in published SWATs [11,17].…”

Background: Good quality information is critical for valid informed consent to trials, but current paper-based consent procedures are potentially unwieldy and can be difficult to comprehend, which may deter people from participating. Multimedia resources may be able to provide more accessible and user-friendly information. We aimed to test whether offering access to a multimedia information resource alongside standard, printed patient information impacted on recruitment rates by conducting a pragmatic 'study within a trial' (SWAT) embedding a trial of a multimedia resource within an existing trial. Methods: The PSM COPD study involved people with mild symptoms of chronic obstructive pulmonary disease (COPD) recruited from primary care being randomised to a nurse-delivered telephone health coaching intervention, or usual primary care. For the SWAT of recruitment procedures, practices recruiting participants were cluster randomised to use either the standard printed patient information materials or standard printed patient information materials with access to a multimedia information resource. The multimedia resource was developed by patient and public involvement (PPI) contributors and researchers, and included study-specific information (e.g. study purpose, risks), and generic information about trials (e.g. confidentiality, randomisation). We developed a list of components and used animations as well as video clips of patients discussing their experiences of participation, matched to these components. The primary outcome was the proportion of participants randomised.Results: Nine point six percent of those receiving standard printed patient information materials and access to the multimedia information resource were recruited, compared to 10.8% in those receiving standard printed materials alone (odds ratio (OR) = 0.844, 95% confidence interval (CI) 0.58 to 1.22). We also found no effects on the proportion of people responding to the invitation (OR = 1.02, 95% CI 0.79 to 1.33) or retention in the trial at 6 (ORs 0.84, 95% CI 0.57 to 1.22) and 12 months after randomisation (ORs 0.80, 95% CI 0.54 to 1.18), respectively.(Continued on next page)

“…By comparison, there was a 29.5% response rate from 200 postal questionnaires sent out in the present investigation. A postal questionnaire, sent without prior contact from the questionnaire's authors, was analyzed recently in Yorkshire and yielded a 15.9% response [46] higher than our technologically focused recruitment method, but lower than a similar postal strategy. The link sent by social media to the contacts of one of the researchers (200 people) received a 45.5% response rate, again here we can only speculate that personal contact will increase response rate.…”

The multimedia resource was developed by PPI contributors and researchers, and included study-specific information (e.g. study purpose, risks), and generic information about trials (e.g. confidentiality, randomisation). We developed a list of components and used animations as well as video clips of patients discussing their experiences of participation, matched to these components. The primary outcome was the proportion of participants randomised. Results 9.6% of those receiving standard printed patient information materials and access to the multimedia information resource were recruited, compared to 10.8% in those receiving standard printed materials alone (OR = 0.844, 95% CI 0.58 to 1.22). We also found no effects on the proportion of people response to the invitation (odds ratio1.02 95% CI 0.79 to 1.33) or retention in the trial at 6 and 12 months after randomization (odds ratios 0.84, 95% CI 0.57 to 1.22 and 0.80, 95% CI 0.54 to 1.18 respectively.) Conclusions The study suggests no benefits of access to a multimedia information resource alongside patient information materials on recruitment. This may reflect the limited engagement of patients with the multimedia resource. Further uses of multimedia resources will need to explore how content can be explicitly matched to user needs and preferences and methods to encourage engagement to see if effects can be enhanced. More SWATs of multimedia into ongoing trials will provide a more precise estimate of effect, and explore further how effects vary by trial context and recruitment process, intervention, and patient population.
