ASPIRE:Adherence to SPIrit Recommendations

DISCO: Study of DISCOntinued Trials

Randomized clinical trials (RCTs) are the method of choice to evaluate therapeutic and prophylactic interventions in health care. Protocols are crucial in the planning and conduct of new RCTs, because they provide a detailed description of the rationale, research question(s), methodology, processes, planned analyses and results dissemination for a new trial. To improve the reporting of trial protocols, the SPIRIT checklist with a minimum set of items to be reported in a protocol was published in 2013. In the Adherence to SPIRIT Recommendations (ASPIRE) project we aimed to assess the comprehensiveness/reporting of RCT protocols in a repeated cross-sectional study to investigate the reporting quality of RCT protocols longitudinally. For this we included a random sample of RCT protocols approved by research ethics committees in Switzerland, Germany, Canada, and the United Kingdom in 2012 and in 2016.  We used the RCT protocols included in ASPIRE in addition to check the proportion of prospectively registered RCTs, prematurely discontinued RCTs (with reasons for discontinuation), RCTs with publicly available results, and RCTs with publicly available protocol (DISCO studies).

In further meta-research studies we are investigating the planning of subgroup analyses, the planning and reporting of patient-reported outcomes, and the use of routinely collected data in RCTs of the ASPIRE sample.  In an other project, we investigate how often and through which sources RCT protocols are made available, using the trial sample from the ASPIRE project."
