This contains up to 13 stations including an unspecified test station that doesn't count toward the overall mark. It is based at the RCOA in London and lasts approximately 1 hour and 45 mins.
This is a traditional OSCE with a bell sounding as you rotate through the different stations, each lasting 7 minutes, followed by a 1 minute information point before entering the next station. There may be a simulator manikin used in one of the stations and there may be a rest station.
The exam is designed to test knowledge and skills and cover a broad selection of the curriculum. The four areas of practice used to select questions from include Data, Equipment, Professionalism and Resuscitation. Data interpretation may include ECGs, Echo images, USS chest images, CT images, and laboratory data.
From my experience the examiners asked structured questions around the data giving the OSCE the feel of a series of small scale vivas.
The examiners reports highlight things done poorly and suggest areas that will continue to be asked, in the 2017 report these included ECG interpretation and presentation of findings, radiology, and calcium. There are some example questions from the FFICM here and here
Each station is marked out of 20 and your pass mark will be derived from the total of the 12 live stations. All stations must be attempted, there is no negative marking and no ‘must pass’ stations.
A pass in the OSCE is valid for two years after which all components of the exam must be retaken.
