A Suicide Attempt Multicomponent Intervention Treatment (SAMIT Program): Study Protocol for a Multicentric Randomised Controlled Trial (preprint)

Background: Suicide has become a first-order public health concern, especially following the negative impact of COVID-19 on the mental health of the general population. Few studies have analyzed the effects of early psychotherapeutic interventions on subjects who have attempted suicide, and even fewer have focused on those hospitalized in non-psychiatric units after a medically serious suicide attempt (MSSA). The main aim of this study is to describe the protocol designed to evaluate the effectiveness of individual psychological treatment for patients hospitalized after an MSSA. The secondary objectives of the study are: 1) to evaluate the impact on quality of life and other psychosocial variables of patients with a recent MSSA who receive early psychological intervention; 2) to analyze the biological, psychological, and clinical impact of early psychotherapeutic treatment on subjects hospitalized after an MSSA. Methods: An experimental, controlled, and randomized trial will be conducted with patients over 16 years of age admitted to two general hospitals. The case intervention group will enroll for 8-sessions of individual psychotherapy, Suicide Attempts Multi-component Intervention Treatment (SAMIT), combining Dialectical Behaviour Therapy (DBT), Mentalization-Based Therapy (MBT), and Narrative approaches, while the control group will receive a treatment-as-usual intervention (TAU). Longitudinal assessment will be conducted at baseline (before treatment), post-treatment, and 3, 6, and 12 months after. The main outcome variable will be re-attempting suicide during follow-up. Discussion: Some psychotherapeutic interventions, usually implemented in outpatient, have proven to be effective in preventing suicidal behaviours. The combination of some of these may be a powerful treatment for preventing future SA in patients hospitalised after an MSSA, which is the most severely suicidal subgroup. Moreover, assessment of the biological, clinical and psychometric impact of this new intervention on patients during the first year after the attempt may help understand some of the multi-level factors associated with the effectiveness of psychotherapeutic interventions in MSSAs. The prevalence of high suicide rates requires the design of effective psychological interventions for their prevention, and also in order to design new pharmacological and psychological treatments.

Trends in medically serious suicide attempts before and after the COVID-19: a four-year retrospective analysis (2018-2022) (preprint)

Background Suicide has become a first-order public health concern after the negative impact of COVID-19 on the general population’s mental health. Several studies have analyzed the trends in suicide attempts (SA) before and after the onset of the pandemic, but few studies focus on the impact of the pandemic on medically serious suicide attempts (MSSA).Methods Participants were 396 hospitalized individuals ≥ 16 years old who made MSSA identified retrospectively through a review of e-medical records between 2018 and 2022 ("pre-COVID-19" and “COVID” periods). The two groups were compared on sociodemographic and clinical variables using Chi-square or Exact Fisher’s tests for categorical variables and a Mann-Whitney test for continuous variables. To study the variation in MSSA over time, MSSA were aggregated monthly. Joinpoint regression analyses were used to assess time trends.Results A sample of 161 MSSA patients, 80 women and 81 men, were selected from 396 admissions after a suicide attempt (SA) in the four years (n = 169 pre-COVID period vs. n = 199 COVID period). Sixty-eight patients with MSSA were admitted during the first period, and 93 during the COVID period. MSSA patients were more likely to be admitted to an intensive care unit during the COVID period than during the pre-COVID period (OR = 3.4620; CI 95%=1.7305–6.9260).Conclusions This study highlights the need for research on suicide risk during and after crisis periods, such as the COVID-19 pandemic. It provides valuable knowledge on the incidence of SA needing hospitalization, MSSA, and highly severe MSSA for four years before and after the pandemic onset.
