My notes

  • They do Caring e-mails, in contrast with comtois2019 who send SMS and the original motto1976 who send letters.
  • This study also had standard inclusion/exclusion with individuals in inpatient care
  • The e-mail schedule was the same as in motto1976
  • Even though there were no statistically significant differences in all-cause or suicide-specific mortality, the IRRs are quite strong (0.77 and 0.42, respectively).
    • The authors explain this by lack of power. They only recruited 28% of the target sample, and overestimated the event rate of suicide.

Objective The purpose of this multisite study was to conduct a randomized controlled trial of an e-mail version of the caring letters (CL) suicide prevention intervention to determine whether the intervention is efficacious in preventing suicide behaviors among U.S. service members and veterans. Method Psychiatric inpatients (N = 1,318) were recruited from four military medical centers and two VA hospitals and randomized to receive either 13 caring e-mails over two years or usual care. Results There were 10 deaths from any cause in the CL group (three suicides) and 14 in the usual care group (seven suicides) during the individual two-year follow-up intervals. There was no statistically significant difference in the rate of all-cause hospital readmission between the study groups (RR = 1.13; 95% CI = 0.94, 1.36). There were no differences observed between groups on self-reported psychiatric hospital readmissions, self-reported suicide attempts, or other measures associated with risk for suicide. Conclusions No firm conclusions about the efficacy of the intervention can be made because the study was inadequately powered. There were no adverse events associated with the intervention, and implementation of the procedures was feasible in the military and veteran hospital settings. These results provide important methodological considerations for caring contact trials in military populations.
