A proper waste management system is very important in healthcare facilities because the overall benefit outweighs the cost. In the healthcare sector, hazardous health care waste (HHCW) consists of wastes that are potentially contaminated by dangerous agents. Identification and segregation of HHCW is harbinger for its proper management. The quantitative analysis study on HHCW had not been done in Qatar government hospitals. This study quantitatively analyzed the current practice for HHCW management in hamad medical corporation (HMC), Qatar. The objective of this study is to provide a first comprehensive assessment of hazardous healthcare waste managements in Qatar and offers an opportunity to improve existing practice. This is a retrospective survey study carried out on secondary data collected from the department of occupational health and safety (OHS), HMC. OHS department collects and keeps records of hazardous wastes produced by HMC. Data on the HMC hospitals’ characteristics from 2017 to 2019 were retrieved from Planning and Statistics Authority’s website. World Health Organization (WHO) formula for calculating HHCW generation rate was used to calculate the rate for HMC. Data analysis results show a steady increase in HHCW generation rate in HMC, the generation rate was 2.6 Kg/patient bed/day, 2.8 Kg/patient bed/day and 3.1 Kg/patient bed/day for the years 2017, 2018 and 2019 respectively. There were also significant variations in HHCW generation rates between hospitals. The highest generation rate was 4.64 Kg/patient bed/day recorded for AWH and the lowest was 0.2 Kg/patient bed/day recorded for mental health and both hospitals contributing 23.18% and 0.29% respectively of HHCW in HMC.

AIM: To assess the diagnostic accuracy,of aminotransferase-to-platelet ratio index(APRI) alone and with antischistosomal antibody(Ab) in patients with hepatitis C virus(HCV) and schistosomiasis coinfection. METHODS: This retrospective study included medical records of three hundred and eighty three Egyptianmen patients who had undergone percutaneous liver biopsy between January 2006 to April 2014 in tertiary care hospital in Qatar for diagnosis or monitoring purpose were selected. Data of patients > 18 years of age were included in the study. The values of HCV RNA titer and antischistosomal antibody titer were also taken into consideration. Patients were excluded from the study if they had any other concomitant chronic liver disease,including; history of previous antiviral or interferon therapy,immunosuppressive,therapy,chronic hepatitis B infection,human immunodeficiency virus co-infection,autoimmune hepatitis,decompensated liver disease,hepatocellular carcinoma,prior liver transplantation,and if no data about the liver biopsy present. RESULTS: Median age of patients was 46 years. About 7.1% had no fibrosis,whereas 30.4%,37.5%,20.4%,and 4.6% had fibrosis of stage Ⅰ,Ⅱ,Ⅲ,and Ⅳ respectively. In bivariate analysis,APRI score,levels of AST,platelet count and age of patient showed statistically significant association with liver fibrosis(P < 0.0001); whereas antischistosomal antibody titer(P = 0.52) and HCV RNA titer(P = 0.79) failed to show a significant association. The respective AUC values for no fibrosis,significant fibrosis,severe fibrosis and cirrhosis of APRI score were 63%,73.2%,81.1% and 88.9% respectively. This showed good sensitivity and specificity of APRI alone for grading of liver fibrosis. But the inclusion of anti-Schistosoma antibody did not improve the prediction of fibrosis stage. CONCLUSION: The study results suggest that noninvasive biochemical markers like APRI are sensitive and specific in diagnosing the degree of fibrosis and cirrhosis in patient
