Abstract

Background: Repetition of hospital-treated self-poisoning and admission to psychiatric hospital are both common in individuals who self-poison. Aims: To evaluate efficacy of postcard intervention after 5 years. Method: A randomised controlled trial of individuals who have self-poisoned: postcard intervention (eight in 12 months) plus treatment as usual v. treatment as usual. Our primary outcomes were self-poisoning admissions and psychiatric admissions (proportions and event rates). Results: There was no difference between groups for any repeat-episode self-poisoning admission (intervention group: 24.9%, 95% CI 20.6-29.5; control group: 27.2%, 95% CI 22.8-31.8) but there was a significant reduction in event rates (incidence risk ratio (IRR)=0.54, 95% CI 0.37-0.81), saving 306 bed days. There was no difference for any psychiatric admission (intervention group: 38.1%, 95% CI 33.1-43.2; control group: 35.5%, 95% CI 30.8-40.5) but there was a significant reduction in event rates (IRR=0.66, 95% CI 0.47-0.91), saving 2565 bed days. Conclusions: A postcard intervention halved self-poisoning events and reduced psychiatric admissions by a third after 5 years. Substantial savings occurred in general hospital and psychiatric hospital bed days.

  • One psychiatric intervention reduced the number of suicide reattempts simply by sending former patients timely postcards inquiring into their well-being.

    “Indeed, one psychiatric intervention reduced the number of suicide reattempts simply by sending former patients timely postcards inquiring into their well-being (see Carter et al. 2013).”

    From The Psychology of Change: Self-Affirmation and Social Psychological Intervention (2014) · cites this paper as Carter et al. 2013

    The Intervention section describes eight postcards sent during the year after discharge, and the Main findings report about 50% fewer repeat hospital-treated self-poisoning events over five years. But the Results report no significant difference in the proportion of patients who had any repeat episode. The paper measures self-poisoning rather than suicide reattempts specifically, so the claim overstates what was reduced. (LLM, conf=0.89)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
