Abstract: Presented is a fecal/urine management system that includes a mattress having an aperture (e.g., catchment aperture) disposed through its top surface. The catchment aperture allows positioning a patient's anus over the aperture when the patient is positioned on the mattress. Accordingly, bodily waste may be collected in the aperture and thus separated from the skin of the patient. To prevent soiling the mattress, a catchment insert is positioned within the catchment aperture. The catchment insert, in one embodiment, includes an annular platform that rests on the top surface of the mattress and catchment bag that is adapted to be positioned within the mattress aperture. The catchment bag and annular platform prevent most or all bodily waste from contacting the mattress. Further, the catchment bag is adapted for removal through the top surface of the mattress with little or no movement of the patient.
