“…In regard to physical illness, the present study finds that physical illness is an important precipitating factor for suicide, especially among the elderly. This finding is consistent with the findings of previous studies (Kim et al, 2011;Zhang et al, 2015).…”

Objectives his study investigated the risk factors leading to serious suicide attempts with high medical severity. Methods Nine hundred and eighty‐two patients who visited the emergency room after attempting suicide were divided into two groups: suicide attempters with high medical severity (25.3%) and those with low medical severity (74.7%). Demographic variables, clinical characteristics, and factors related to each suicide attempt were compared between the two groups. Multivariate logistic regression analysis was conducted to investigate risk factors for high medical severity in patients’ current suicide attempts. Results The results show that suicide attempters with high medical severity had more severe depression and psychological disturbances such as agitation, intense emotions, and self‐reproach. Suicide attempters with high medical severity also had more serious risk factors for suicide such as repetitive/intense/continuous thoughts of suicide, suicidal planning, and a stronger wish to die. School/work problems and physical illnesses were related to high medical severity with more lethal methods. Logistic regression demonstrated that school/work problems, total risk rating, severity of suicidal ideation, and agitation were risks for more serious suicide attempts, whereas more frequent lifetime suicide attempts were a protective factor. Conclusion This study demonstrates that suicide attempters with high medical severity had more severe psychopathologies and risk factors related to suicidal behavior than those with low medical severity.

“…Established suicide risk attempt factors include anxiety disorders 38,39 , bipolar disorders 40 , substance abuse 6,41,42 , pain 43 , disability 44 , bereavement 45 , and more. Prior studies have predominantly examined the clinical and statistical relationship among these risk factors and suicide attempts through univariate analysis or simple logistic regression.…”

Suicide is the tenth leading cause of death in the United States (US). An early-warning system (EWS) for suicide attempt could prove valuable for identifying those at risk of suicide attempts, and analyzing the contribution of repeated attempts to the risk of eventual death by suicide. In this study we sought to develop an EWS for high-risk suicide attempt patients through the development of a population-based risk stratification surveillance system. Advanced machine-learning algorithms and deep neural networks were utilized to build models with the data from electronic health records (EHRs). A final risk score was calculated for each individual and calibrated to indicate the probability of a suicide attempt in the following 1-year time period. Risk scores were subjected to individual-level analysis in order to aid in the interpretation of the results for health-care providers managing the at-risk cohorts. The 1-year suicide attempt risk model attained an area under the curve (AUC ROC) of 0.792 and 0.769 in the retrospective and prospective cohorts, respectively. The suicide attempt rate in the "very high risk" category was 60 times greater than the population baseline when tested in the prospective cohorts. Mental health disorders including depression, bipolar disorders and anxiety, along with substance abuse, impulse control disorders, clinical utilization indicators, and socioeconomic determinants were recognized as significant features associated with incident suicide attempt.

In this study, we focused on individuals aged 80 or older, finally, 2058 residents aged 80 or older were included as our target population excluding those with missing data on ADL/IADL or chronic diseases.…”

BackgroundBoth multimorbidity and activities of daily living (ADL) disability and instrument activities of daily living (IADL) disability are common among elderly individuals. ADL/IADL disability may reduce individuals’ capacities for independent living and quality of life. This study aimed to examine the association between multimorbidity and ADL/IADL disability.MethodsA multi-stage cluster sample of 2058 residents aged 80 or older was investigated in Shanghai, China. Multimorbidity was defined as the simultaneous presence of two or more chronic diseases with ten common chronic conditions under consideration. Subjects who responded that they “need partial or full assistance” to any ADL/IADL items were defined as having ADL/IADL disability. We examined the association of multimorbidity with ADL/IADL disability, adjusted for socio-demographic characteristics by using logistic regression.ResultsOf respondents, 23.23 % had ADL disability, 37.90 % had IADL disability, and 49.17 % had multimorbidity. After adjusted socio-demographic characteristics, a graded association was showed between ADL disability and the quantity of chronic conditions: odds ratio (OR) for 1 condition, 1.53(95 % confidence interval [CI], 1.04-2.24); OR for 2 conditions, 2.06(95 % CI, 1.43-2.96); OR for 3 conditions, 3.23(95 % CI, 2.14-4.86); OR for 4 or more conditions, 5.61(95 % CI, 3.26-9.66). Similar associations were also observed between the quantity of chronic conditions and IADL disability.ConclusionsThe quantity of chronic conditions had relatively strong association with both ADL and IADL disability. Initiating prevention of additional chronic conditions and interventions on clusters of diseases may decrease the potential risk of ADL/IADL disability. Additionally, more attention should been given to the older low-income women living with relatives/non-relatives with multimorbidity.
