Pattern and outcome of acute organophosphate poisoning at health facilities of Harari Region, Eastern Ethiopia

Introduction: Pesticides are frequently used by plant cultivars to control pests that could affect yield. Although many local farmers in Eastern Ethiopia use organophosphate insecticides extensively for the production of khat, the pattern and treatment outcome of acute poisoning of these organophosphates has been poorly quantified and reported in this region. Materials and Method: A cross-sectional study design was employed at two public hospitals found in Harari region, Ethiopia. The data were collected through face-to-face interviews and card review, then analyzed with SPSS version 20. Pearson’s Chi-square test was used to compare independent variables with the treatment outcome. Statistical significance is defined at 95% confidence interval of odds ratio not including 1 or p < 0.05. Results: A total of 135 cases of organophosphate were admitted in the emergency departments of the hospitals during the study period. 42.2% of participants were adolescents (age: 11–20 years) while the mean age of all participants was 18.8 ± 12.9 years with a range of 1–61 years. 73.7% of the study participants were rural residents. The result showed that 47.4% of the cases were exposed to the poison accidentally. Family disharmony was the common reason among cases poisoned intentionally. The mean time elapsed between poisoning and reaching the health facility was 3.1 h. Atropine was administered for 47% of the cases. About 11% of cases expired following the poison. The home remedy given, lag time, and residency were found to be factors significantly related to poor treatment outcomes. Conclusion: Easy availability, low cost, and excessive popularity of organophosphate use as pesticides in Eastern Ethiopia have increased the incidence of ingestion, resulting in increasing intentional and unintentional poisoning. In the present study, accidental exposure accounts for 47.4%.
