Survival, hospitalization charges and follow-up results in critically ill patients.

In 226 consecutive critically ill primarily postoperative patients, we determined survival and quality of life, hospitalization charges, and consumption of blood and blood products. The patients were physiologically unstable and required intensive physician and nursing care. By one month, 123 patients had died (54 per cent), 70 were still hospitalized, and 31 were home; only one of 103 survivors had fully recovered. By 12 months, 164 patients (73 per cent) had died, 10 were still hospitalized, and 51 were home. Twenty-seven of 62 survivors had fully recovered. Hospitalization charges averaged $14,304 per patient. The total charge for blood and blood fractions was $617,710--21 per cent of the total hospitalization charge; $515,711 (83 per cent) of the blood charge went to 164 nonsurvivors, whereas $101,939 (17 per cent) went to the 62 survivors. These data document the use of increasingly limited resources in the management of critically ill patients. The medical profession must make difficult decisions to allocate these resources effectively.

Stability of human enteroviruses in estuarine and marine waters.

Studies of the effects of temperature and salinity on the survival of three enteric viruses (poliomyelitis type 1, echovirus-6, and coxsackievirus B-5) under controlled laboratory conditions and in situ indicate that temperature rather than salinity is the critical factor affecting their stability, in that the higher the temperature the more rapid was the loss of viral infectivity. In the laboratory studies, all three viruses were quite stable at 4 degrees C, with infectious virus still detectable after 46 weeks of incubation. In situ studies on virus survival in free-flowing estuarine or marine waters showed that, although the viruses were more labile in natural waters than in the laboratory studies, they persisted for several months, in some cases during the winter months. At all temperatures and salinities, coxsackievirus B-5 was the most stable, echovirus-6 was intermediate, and poliovirus 1 was the least stable of the viruses tested.
