The aim of our research was to investigate the diseases of 0-18 year old patients who were admitted to the 'Muratsan' University hospital complex(UHC) Intensive care unit (ICU) and toxicology for the last 7 years, including cases that have been reported from the dispensary with or without referral.A retrospective study was performed using medical charts up to 7 years (2012-2018) from 'Muratsan'(UHC) ICU and toxicology. The overall number of patients was 5152, among them 3074 were male and 2078 were female.This study included cases that have been reported by the 'Muratsan'UHC ICU and toxicology from the dispensary with or without referral.The number of patients who were referred from the polyclinics of Yerevan is 41(0.7%). 23(56.1%) of them had Acute respiratory infections(ARI), 3(7.3%)-Acute Intoxications(AI), 5 (12.2%)-Acute Drug Intoxications(ADI) and 2(4.9%)-allergic disorders, 8(19.5%) other disorders*. The referred patients were divided into 4 age groups(0-1,1-7,7-14,14-18), the first group-10, the second-27, the third-3 and the fourth-1 case. 24%-moderate, 64%-severe and 11%-extremely severe cases (the level of severity was absent in 1% of cases).53 patients(1%) were referred from regional polyclinics, 20 (37.7%) of them had ARI, 13(24.5%)-AI, 11(20.8%)-ADI and 2(3.8%)-allergic disorders, 7(13.2%) other disorders. The first age group included-6, the second-42, the third-5 and the fourth-0 cases. 36%-moderate, 57%-severe cases(the level of severity was absent in 7% of cases).Out of 2414 patients who were admitted to hospital without referral 519(21.5%) had ARI, 859(35.6%)-AI, 575 (23.8%)-ADI and 87(3.6%)-allergic disorders.374(15.5%)-other disorders. The first age group included-300, the second-1832, the third-209 and the fourth-73 cases. 42%-moderate, 54%-severe and 2%-extremely severe cases(the level of severity was absent in 2% of cases).*Diabetes mellitus, epilepsy, cancer, hematological disorders, etc.ARIs are more prevalent in patients who have been referred from polyclinics, while the patients without referral had mostly ADIs and AIs. The hospitalization without referral was rather high, which suggests that the primary chain of trust has decreased.
