Relative accuracy of social and medical determinants of suicide in electronic health records

Abstract: Objective: This paper compares the accuracy of predicting suicide from Social Determinants of Health (SDoH) or history of illness. Population Studied: 5 313 965 Veterans who at least had two primary care visits between 2008 and 2016. Study Design: The dependent variable was suicide or intentional self-injury. The independent variables were 10 495 International Classification of Disease (ICD) Version 9 codes, age, and gender. The ICD codes included 40 V-codes used for measuring SDoH, such as family disruption, … Show more

“…Our finding that NLP and LexisNexis SDOH variables improve model prediction accuracy is broadly consistent with prior studies of NLP and SDOH variables predicting suicide, although to our knowledge, no prior studies investigated these associations among postdischarge psychiatric inpatients. Four results about these predictors are especially noteworthy in terms of potential clinical implications.…”

“…The main limitation is our ability to identify PEI and PEH from ICD-10-CM and admission codes. Our findings might not be generalizable to all PEI and PEH hospitalized for COVID-19, and ICD-10-CM codes are likely insufficient to identify all hospitalized PEI . We included admission codes in our PEI definition to broaden the scope, which provided more conservative estimates than ICD-10-CM codes alone.…”

“…Our findings might not be generalizable to all PEI and PEH hospitalized for COVID-19, and ICD-10-CM codes are likely insufficient to identify all hospitalized PEI. 35 , 36 We included admission codes in our PEI definition to broaden the scope, which provided more conservative estimates than ICD-10-CM codes alone. For PEH, ICD-10-CM codes are a more established method of identification but are underused, and hospitals might not have standardized methods for recording housing status in electronic health records.…”

“…The primary exposures of interest were adverse SDoH documented using ICD-9-CM codes captured during clinical visits in the year before the index date. Adverse SDoH were classified into 9 categories developed by Torres et al 5 : (1) alcoholism and drug addiction in the family; (2) encounter for mental health services for victim and perpetrator of abuse or history of abuse; (3) other problems related to primary support group, including family circumstances; (4) problems related to care provider dependency; (5) problems related to education and literacy; (6) problems related to employment and unemployment or occupational maladjustment; (7) problems relating to housing and economic circumstances; (8) problems related to legal circumstances; and (9) problems related to other psychosocial circumstances. See Torres et al 5 for the list of specific ICD-9-CM codes included in each category.…”

“…The main purposes of this study were to identify the prevalence of ICD-9-CM codes related to adverse SDoH among individuals who died by suicide between 2000 and 2015 and to examine the associations between documented adverse SDoH and suicide. Although we anticipated that the prevalence of adverse SDoH-related diagnosis codes would be low, given that these codes may have been underutilized during the ICD-9 era, [5][6][7] we hypothesized that, as supported by past literature, [7][8][9][10][11][12][13] adverse SDoH would be associated with increased suicide risk. Observing such associations would provide additional support for increased standardized documentation of SDoH in health care settings, including for use in suicide prevention efforts.…”
