Abstract
Background: Evidence increasingly suggests that suicide victims are highly likely to visit a primary care provider within one month of the suicide event. However, it would be impossible for primary care providers to act as gatekeepers and thus screen all patients for suicidal ideation or attempts. Therefore, we aimed to investigate potential differences in the chief diagnoses received by primary care patients with and without suicidal ideation, as this information may provide clues and predict patients at risk of committing suicide.
Methods: This cross-sectional study included 1,211 Korean adults aged ≥20 years who had participated in the Korea National Health and Nutrition Examination Survey during 2014 and provided information about their histories of suicidal ideation and visits to primary care providers. Multiple logistic regression analyses were used to examine whether suicidal ideation was associated with specific diseases after controlling for age, household income, education, occupation, marital status, smoking, alcohol consumption and physical activity.
Results: Among primary care patients, the sample-weighted percentage of suicidal ideation was 11.8%. The diagnoses of neoplasm and mental disorder were associated with a higher likelihood of suicidal ideation (odds ratio; OR [95% confidence interval, CI]: 8.32 [1.01–68.56] and 6.19 [1.72–22.33], respectively). Notably, diseases of the musculoskeletal system and connective tissue were also associated with suicidal ideation (OR [95% CI]: 1.93 [1.09–3.43]).
Conclusions: The observed visit patterns and correlations of certain diagnoses with suicidal ideation suggest that primary care physician should pay careful attention to their patients with mood or musculoskeletal disorders and consider screening to determine the risk of suicide.
