Waste was collected in different categories of non-infectious, sharps, infectious, infectious plastics, and pathological waste which were measured daily for fourteen (14) consecutive days in all hospitals by using a weighting scale and observational checklist to document related waste management information and the assessment of the healthcare waste generation in each hospital. The average general healthcare waste generation rate per healthcare ranges from 298.9 kg/day to 1554.4 kg/day. The high fluctuation in general medical waste was established to be attributed to specialization difference between one hospital to the other, and the large number of in-patients and out patients between hospitals. The overall average sharps waste generation rate was established to range from 8.5 ± 2.7 - 13.9 ± 1.8 kg/day. Higher values of sharps waste generated observed at Muhimbili hospital are due to emergency cases referred to from other hospitals located within the city and from the surrounding districts and other regions of the country. The results from this study, raise alarm to hospital administrators, and other health stakeholders working in related fields to give special attention and priority in setting a related share in their budgets for proper management of medical waste in their health facilities.展开更多
