Mechanism of prophylaxis by silver compounds against infection of burns.
To clarify tthe mechanism by which local application of silver compounds protects burns against infection, an ion-specific electrode was used to measùre the concentration of silver ions in solutions. By this method it was shown that in burn dressings silver ions were reduced to a very low level by precipitation as silver chloride. The antibacterial effect was found to depend on the availability of silver ions from solution in contact with precipitate. Between 10(-5) and 10(-6) molar silver nitrate solution in water was rapidly bactericidal. The minimal amount of silver nitrate causing inhibition of respiration of skin in tissue culture was about 25 times the minimal concentration of silver nitrate that inhibited growth of Pseudomonas aeruginosa.

Factors associated with length of stay in a mid-sized, urban hospice.
A recent study by Frantz et al. investigated the relationship between length of stay (LOS) and several factors in a small, rural hospice and found significant differences in LOS by primary physician specialty, referral source, and diagnosis (American Journal of Hospice & Palliative Care, March/April 1999). The purpose of the present study was to replicate and extend the Frantz et al. study in a midsized, urban hospice setting and to examine the relationship of LOS with additional variables, such as living status, discharge status, race, and religion. Significant differences in LOS by gender, diagnosis, physician specialty, referral source, type of insurance, living status, and discharge status were found. No significant differences in LOS were found by race, religion, and place of death. Results are interpreted in the light of previous research findings regarding LOS and in the context of the sample size. Strategies are suggested for increasing patients' LOS.
Factors in hospice patients' length of stay.
Many hospice patients are referred comparatively late in the course of their disease progression, therefore minimizing the time of services to the patient, caregivers, and families. Untimely referrals can create organizational, clinical, and emotional problems for all involved; a better understanding of the factors related to length of stay (LOS) in hospice is necessary. This study investigated the relationship between LOS and selected variables. There were significant differences in LOS by diagnosis, physician type, and referral source. No significant differences were found in LOS by gender or insurance type. Factors related to LOS can assist hospices in identifying those particular patients more likely to have longer stays. Additionally, administrators may tailor their programs to meet the needs of the individual hospice.
