The study of suicide among psychiatric inpatients in Denmark between 1997 and 2006 by Madsen and associates is an important contribution to the literature because it is the largest study on the topic to date, it is one of only a few studies to have used systematically collected prospective data, and it is the only study to have considered the effects of time at risk due to differences in the duration of hospital stay. We recently conducted a systematic review and meta-analysis of 28 controlled studies on this topic and found that the length of hospital stay was significantly associated with the risk of suicide as an inpatient. It is therefore likely that at least some of the findings of earlier studies were affected by time at risk.
