Target follow-up type
Description of intervention(s) / exposure
The exposure is an attack of acute gout.
We will do patient questionnaires, metrology(swollen and tender joint count), blood tests, a Coronary CT Angiogram. The total duration of follow-up for each patient is 6 months.
Patients will be assessed monthly, the first and last visit might last hour, the other visits will last about 20 minutes.
Intervention code [1] 315425 0
Diagnosis / Prognosis
Comparator / control treatment
The group will be observed prospectively. Those who have a n acute flare of gout will be considered high risk those who do not, low risk (reference comparator).

Painful joints, Using a questionnaire which asks the participants to identify which joints are painful.
The tool is comonly used, and generally called a "painful joint count" based on the 68 joints of the Richie articular index, and uses a homunculous to as shown here: http://www.pmmonline.org/doctor/approach-to-clinical-assessment/examination/describing-joints

Statistical methods / analysis
No pilot data is available to power this study, so a pragmatic decision has been made to include 14 patients to generate pilot data, assuming 50% will flare on allopurinol initiation. Descriptive statistics (such as mean with standard deviations for continuous variables, frequencies with percentages for categorical variables) will be used to summarise the two study groups. The differences between the study groups will be compared using t-test for continuous variables and chi-square tests for categorical variables.
