Objective: Risk factors for inpatient suicide are different from those in the general population. We examined sociodemographic and clinical variables of patients who committed suicide as an inpatient in a psychiatric hospital in India.
Methods: Matched retrospective nested case-control design was adopted. Ten patients who died by suicide as inpatients between 2000 and 2013 were included, along with fifty controls, matched with respect to age, sex, diagnosis, and period of admission.
Results: Suicide completers were mostly unskilled in occupation (P = 0.03), had a history of past suicide attempts (P < 0.001), shorter duration of hospital stay (P = 0.001), poorer improvement on psychopathology (P = 0.02), and were having more suicidal ideation (P = 0.02). Significantly more completers were receiving antidepressants (P = 0.04).
Conclusion: This study adds to the existing sparse literature on inpatient suicides from Asia. Strength of the study was close matching between case and controls and blindedness. Limitations were retrospective design, and variations in prescription behavior and treatment decisions.
