Suicide risk peaks in first week of psychiatric hospitalisation and post-discharge.

Risk factors: Time since most recent psychiatric hospitalisation, main diagnosis at recent hospitalisation, length of recent hospitalisation, total number of psychiatric admissions. Conditional logistic regression was used to assess risk factors, and calculations were adjusted for income, area of residence, and marital status in year before suicide, as well as for other risk factors analysed. Odds ratios were calculated for men and women separately.
