The pooled estimate of the number of admissions per suicide calculated using 39 studies reporting 150 independent samples was 676 (95% CI: 604–755). Recent studies tended to report higher numbers of admissions per suicide than earlier studies. The pooled estimate of suicide rates per 100 000 in‐patient years calculated using 27 studies reporting 95 independent samples was 147 (95% CI: 138–156). Rates of suicide per 100 000 in‐patient years tended to be higher in more recent samples, in samples from regions with a higher whole of population suicide rate, in samples from settings with a shorter average length of hospital stay and in studies using coronial records to define suicide.</p> </sec> <sec id="acps12383-sec-0004" sec-type="section"> <title>Conclusion</title> <p>Rates of in‐patient suicide in psychiatric hospitals vary remarkably and are disturbingly high.
