Objective: Suicidal victims often reach Intensive Care Units (ICU), if they manage to reach a hospital, and the anesthesiologist get involved in their management. We aimed to evaluate the incidence of suicidal patterns, methods being used and seasonal variations in the frequency of suicide victims admission at Intensive Care Unit (ICU) of Peoples Medical College Hospital (PMCH), Nawabshah (Pakistan).Study design: Retrospective studyMethodology: A cohort study was conducted over a four and a half years (January 2014 to August 2018), including suicidal cases of both sexes received at ICU, PMCH, Nawabshah, from six districts of interior Sindh. Cases were selected on the basis of information from hospital record files after the approval of hospital ethical review committee. Findings were tabulated and analysed.Results: This study revealed that out of a total of 685 cases, 391 (57.08%) were males and 294 (42.92%) were females. Eighty males (11.67%) and 68 (9.93%) females could not be survived while two cases (0.29%) were referred to Karachi during the study period. The highest incidence of suicidal attempts and suicidal deaths were 164 and 38 during 2017 and 2014 respectively. Males were the predominant victims of suicide with a male to female ratio of 2:1.7. The most common method used for suicide was poisoning 98.77% (n = 656) followed by hanging 3.21% (n = 22) and drug overdose 1.02% (n = 07). A seasonal surge in autumn (August 17.81%) was noted.Conclusion: Males were the predominant victims of suicide in rural areas of interior Sindh Province of Pakistan. The most common method used for suicide was poisoning.Citation: Khaskheli MS, Shaikh S, Meraj M, Irfan R, Tabassum R. Epidemiology of reported suicidal attempts in rural areas of Sindh, Pakistan.
