A pilot study is a small scale preliminary study conducted in order to evaluate feasibility of the key steps in a future, full-scale project. Pilot studies can teach researchers about any amendments they will need to make to the design of the future study, in order to minimise waste of time and resources.
This blog provides a detailed overview of the concept of ‘blinding’ in randomised controlled trials (RCTs). It covers what blinding is, common methods of blinding, why blinding is important, and what researchers might do when blinding is not possible. It also explains the concept of allocation concealment.
This blog provides a basic overview of: 1) what a meta-analysis is; 2) why they’re considered the ‘gold standard’ of evidence; and 3) how a meta-analysis is carried out.
This blog explains what allocation concealment is & why it’s important, in terms of preventing researchers from (intentionally or otherwise) influencing which participants are assigned to a given intervention group.
Outcome switching is a major problem in clinical trial reporting that distorts the evidence doctors and patients use to make real-world clinical decisions. Numerous prevalence studies have already shown this to be an extremely common problem, even in top medical journals. However the CEBM Outcome Monitoring Project (COMPare) has taken a new approach: writing to journals to correct the record on individual trials, in the hope that individual accountability and open data sharing will help solve this important problem. Our main question was: how will the journals respond? This blog tells the story of COMPare so far.
Patients, carers and members of the public offer a unique perspective in health and social care research, adding to the expertise of the research team. Improving healthcare services will only be possible by involving the people accessing those services.
