Suicidal ideation in patients with diabetes and childhood abuse - The mediating role of personality functioning: Results of a German representative population-based study

AIMS

Suicidal ideation (SID) in patients with diabetes mellitus is increasingly acknowledged. Still, the underlying mechanisms are unclear. We examined SID prevalences in patients with diabetes, its association with different types of abuse, and a mediating effect of personality functioning.

METHODS

In a representative population sample (N = 2,515), diabetes, SID, abuse (ICAST-R), personality functioning (OPD-SQS), and depression/anxiety (PHQ-4) were assessed by self-report. Statistical analyses comprised Chi2-Tests, logistic regression and mediation analyses.

RESULTS

The prevalence of SID (21.8 %) was three fold higher in patients with diabetes compared to the general population. Abuse further increased the likelihood to report SID in diabetes patients (sexual: 48.1 % vs. 18.2 %; χ2(1) = 12.233, p <.001; emotional: 35.7 % vs. 15.7 %; χ2(1) = 10.892, p <.001). A dose-response relationship between the number of abuse experiences and SID was observed (one abuse experience: OR = 1.138, 95 %-CI [0.433, 2.990], p =.793, >2 abuse experiences: OR = 2.693, 95 %-CI [1.278, 5.675], p =.009). Impaired personality functioning had an indirect effect on the association between emotional abuse and SID (b = 0.25, 95 %-CI [0.037, 0.551]).

CONCLUSIONS

Diabetes patients experience increased SID prevalences, especially those with emotional or sexual abuse. In individuals with a history of emotional abuse, impaired personality functioning partly explained SID and should therefore be considered and addressed in this patient group.

Suicide capability within the ideation-to-action framework: A systematic scoping review

Suicide capability is theorised to facilitate the movement from suicidal ideation to suicide attempt. Three types of contributors are posited to comprise suicide capability: acquired, dispositional, and practical. Despite suicide capability being critical in the movement from ideation-to-attempt, there has been no systematic synthesis of empirical evidence relating to suicide capability that would enable further development and refinement of the concept. This study sought to address this synthesis gap. A scoping review was conducted on suicide capability studies published January 2005 to January 2022. Eleven electronic databases and grey literature sources were searched returning 5,212 potential studies. After exclusion criteria application, 90 studies were included for final analysis. Results synthesis followed a textual narrative approach allocating studies based on contributors of suicide capability. Most studies focused on investigating only one factor within contributors. Painful and provocative events appear to contribute to acquired capability more so than fearlessness about death. Whilst emerging evidence for dispositional and practical contributors is promising, the small number of studies prevents further conclusions from being drawn. An unexpected additional cognitive contributor was identified. The focus of a single factor from most studies and the limited number of studies on contributors other than acquired capability limits the theoretical development and practical application of suicide capability knowledge. Given that suicide is a complex and multifaceted behaviour, future research that incorporates a combination of contributors is more likely to advance our understandings of suicide capability.

Predictors of clinical severity in subjects attending the Emergency Department for substance use: a ten-year cross-sectional study

OBJECTIVE

Substance-related referrals to the Emergency Department (ED) are rising. Multiple substance use is frequent, and psychiatric patients represent a high-risk population. Our study aimed at identifying risk factors for increased severity in ED attendances for substance use.

METHODS

We retrospectively evaluated consecutive patients attending the ED over ten years for substance-related problems, subdivided according to the triage code as having a life-threatening (LT), potentially life-threatening (P-LT), and non-life-threatening (N-LT) condition.

RESULTS

Substance/drug intake for deliberate self-harm was a risk factor for being classified as LT compared to both P-LT (OR = 6.357; p ≤ 0.001) and N-LT (OR = 28.19; p ≤ 0.001). Suicide attempts (OR = 4.435; p = 0.022) and multiple substance use (OR = 1.513; p = 0.009) resulted as risk factors for P-LT, compared to N-LT. Psychiatric diagnosis (OR = 1.942; p = 0.042) and multiple substance use (OR = 1.668; p = 0.047) were risk factors for being classified as LT rather than N-LT.

CONCLUSIONS

In our sample, self-harming overdoses were the strongest risk factor for highest overall severity in a real-world setting. Psychiatric disorders and multiple substance use also increased the risk for greater severity at presentation. Substance use worsens patients' clinical picture and management, suggesting the need for consultation-liaison psychiatry services in emergency contexts and highlighting the role of EDs as key sites for identification and early intervention.
