Clinical profile and Prevalence of poisoning patients presenting to the emergency department of a teaching hospital in Kerala: A retrospective comparative study before and during COVID-19 pandemic

Abstract

Background: Emergency physicians must be updated about the variations in poisoning pattern during Covid19 pandemic. Limited data exist on the incidence and characteristics of patients presenting with poisoning in Indian Emergency Departments (ED) during the COVID 19 pandemic. Hence, we aimed to explore the impact of Covid19 pandemic on poisoning cases presenting to the ED.Methods: This cross-sectional retrospective study was conducted on poisoning patients presenting to ED during the pandemic period (April 1-October 30, 2020 (period 2)), and a matching period before the pandemic (September 1,2019 to March 31, 2020 (period 1)). The rate of prevalence and clinical profile were compared between period 1 and 2 using appropriate statistical test.Results: A total of 111 (periods 1 = 57, and periods 2 = 54) cases were analysed. Poisoning prevalence rates had slightly increased by 2.7% before the pandemic (51.33%) in comparison to during the pandemic (48.6%) period (p=0.3). Females were predominant in both periods, and the mean age of 32.5 years. The predominant (57%) patient age group was 15-34 years. 36.9% (n=41) patients consumed multiple poisons, 19.8% (n=22) consumed paracetamol, and 14.4% (n=16) patients consumed psychiatric medications. Before lockdown, 27.02% (n=30) patients presented within 3 hours ingestion, and 21.6% (n=24) presented after 3 hours ingestion (p=0.12). A significant delay in arrival of poisoning cases during lockdown (p= 0.12) with increased hospital admission (p=0.03) was observed.  A psychiatric disorder was observed in 36.03% cases. Majority of the cases were admitted in the ICU, and 0.9%(n=1) death was recorded.Conclusions: This is the first Indian study that describes the incidence of poisoning cases and their pattern during the COVID 19pandemic period, study revealed that increased mental health crisis in low resource settings in rural Kerala affects predominantly young population. Study implies the importance of priming the mental health care professionals to initiate their mental health screening programmes.
