The OMACS study aims to follow-up all cardiac surgery patients who consent study in order to estimate, for example, the proportion of cardiac surgery patients experiencing a Major Adverse Cardiac Event (MACE) such as a heart attack or a stroke. These data will allow audit of cardiac surgery services and, with respect to research, provide high quality data to inform the design of future studies, e.g. the characteristics of patients having cardiac surgery, the frequencies of complications after surgery and patients’ longer term outcomes.
Due to the large target population, and long term nature of OMACS, we are embedding a number of sub-studies or ‘studies within a trial’ (SWAT). The first will examine different presentation styles and formats of the paper information leaflets (PILs) provided to potential participants. We will survey participants’ preferences and test whether the different formats affect the consent rate to the study. Potential participants will have an equal chance of receiving the information in three different formats, one of which is used routinely, the other two representing new styles. The content of each format will be the same. Participants will not be informed about this nested study. 
This SWAT has now closed, and the results will be used to inform the format of the PIL used for OMACs and other studies in our portfolio.

Rachel Maishman - Outcomes in RCTs: assessment, reporting and integration in decision-making

'Assessing recovery after surgery in clinical trials is important when comparing different treatments. We need to develop an outcome measure whose component parts represent different aspects of recovery and can be measured without bias. This is important in surgical trials where the surgical team often need to know which treatment group trial patients are in. The aim of my PhD is to develop an outcome that can be used to assess recovery that will take into account information about the complications that patient’s experienced during their post-operative stay as well as other routinely collected data about their health status during their stay.'

Sia Gravani - Improving feasibility study designs and trial conduct to enhance trial quality and results

'The main aim of my PhD was to investigate ways in which trial-specific training is provided during site initiation and explore trial managers’ and site staff views on the importance of trial-specific training during study conduct (the ATLAS study). Based on the findings of ATLAS, a more standardised approach in the form of a training toolkit was developed that can be utilised by trial management teams when planning staff training within clinical trials.'
