Recruitment and follow-up of the prospective repetition cohort.
DSP admissions reported to all the hospital in KD and suicides reported to police stations were collected from 2011–2013. Data was collected regarding the incidence and demographic patterns of DSP and suicide. Details of the cohort of DSP patients presenting in 2011 (n = 4022) were matched with subsequent records of presentations in in 2012 and 2013 using a software with high sensitivity to identify repeat presentations. Manual confirmation was done in order to confirm repetitive events with a higher degree of specificity.
