Characteristics of suicidal poisoned patients admitted to tertiary care center during COVID-19 pandemic

Background Suicidal poisoning is a major concern during the COVID-19 pandemic that has several physical and mental hazards. This study aimed to evaluate the characteristics of suicidal poisoned patients admitted to a tertiary poison control center during the pandemic lockdown and assess COVID-related knowledge and attitude among those patients to identify the high-risk group for suicide. This cross-sectional study was conducted on acutely poisoned patients admitted to Tanta University Poison Control Center from June to December 2020. Upon admission, socio-demographic data, causative poisoning agents, COVID-related knowledge and attitude, Hamilton Anxiety Rating Scale (HAM-A), and Hamilton Depression Rating Scale (HAM-D) were collected from all participants. Results A total of 254 poisoned patients were categorized into suicidal (85.04%) and accidental (14.96%) poisoning groups. The former was caused mainly by phosphides and was significantly associated with a history of using psychotropic medications and high HAM-A and HAM-D results. Logistic regression analysis showed that a history of psychiatric illness, low attitude scores, and high HAM-D scores were significant risk factors for suicidal poisoning. Conclusions Considerable number of suicidal poisoned patients had moderate-to-severe depressive symptoms, highlighting the importance of providing specialized psychiatric services in poisoning centers, particularly among vulnerable populations, to prevent the overwhelming repeated suicidal attempts.
