Given that no comprehensive studies have yet been conducted on treatment of infectious wastes in hospitals of Qom City, this research was performed with the purpose of investigating the treatment methods used in these hospitals and monitoring the performance of waste elimination devices.
Required information was obtained through in-person visit and observing the current situation, and the variables affecting waste treatment were extracted based on the type of treatment systems, and were collected, and accordingly, biological monitoring tests were designed for the studied hospitals. The data were analyzed using Fisher's exact test.
In this study, from 9 active hospitals in Qom Province, only 3 hospitals were equipped with waste treatment system. In hospital A, growth of Bacillus stearothermophilus spore were observed in 6.25% of the samples, while no microbial growth was recorded in hospital B. The initial investment to buy the machine in hospital A was about four times than that of hospital B.
The findings of this study showed that treatment device of hospital B is more appropriate compared to the devices of hospital A due to complete destruction of spores, lower cost (for purchase), and maintenance.

This is a descriptive-analytic study which was carried out on 45 samples of influent water to dialysis machines in hospitals of Qom. Then results comparised with related standards. The results showed that means of anions in this study were below AAMI and EPH standards. It should also be mentioned that in few samples، these amounts were above the standard levels. Then it should be analysed influent water to dialysis machine continually.

Trace elements in dialysis liquid significantly disturb the trace elements in dialysis patients. Because, contaminants in drinking water enter the circulatory system via gastrointestinal tract while in dialysis liquid directly enter the blood during haemodialysis. Therefore, complying with the standards for dialysis water is indispensible. This study was carried out to determine cathion concentrations in influent water to dialysis machines and to compare with established standards in the hospitals of Qom province in 2010. This is a descriptive-analytic study carried out on 45 samples in influent water to dialysis machines in hospitals of Qom province. Since only 3 hospitals in Qom province had dialysis units, 15 samples were taken from each hospital. Chemical analysis was done through titration method using Flame photometer, pH-meter, and EC-meter. Kations under study (Calcium, Magnesium, Sodium and Potassium) were below AAMI and EPH standards for all samples. The results of this study show that all the measured parameters in the hospitals are below the standard levels. In other words, the patients are in better conditions regarding complications of above-mentioned factors.
