The physician's perception of medical error and its application to the development of an educational training tool.

It is becoming clear that if we are to impact the rate of medical errors it will have to be done at the practicing physician level. The purpose of this project was to survey the attitude of physicians in Alabama concerning their perception of medical error, and to obtain their thoughts and desires for medical education in the area of medical errors. The information will be used in the development of a physician education program.

Podcasting and the use of portable music/video players at the School of Nursing

Introduction As students become more connected with the internet and other current technologies, the school of nursing has continued to investigate more innovative, meaningful, and effective uses of technology. One particular technology whose use has increased is the portable music/video player. Like the cell phone, mp3 players and iPods have become a standard accessory for students. To capitalize on this popular technology the School has started several pilot projects involving podcasting under graduate and graduate nursing classes and has also been involved in one research project using video iPods.

Consumer Health Information for Asians (CHIA): a collaborative project.

According to the 2000 United States Census, the Asian population in Houston, Texas, has increased more than 67% in the last ten years. To supplement an already active consumer health information program, the staff of the Houston Academy of Medicine-Texas Medical Center Library worked with community partners to bring health information to predominantly Asian neighborhoods. Brochures on health topics of concern to the Asian community were translated and placed in eight informational kiosks in Asian centers such as temples and an Asian grocery store. A press conference and a ribbon cutting ceremony were held to debut the kiosks and to introduce the Consumer Health Information for Asians (CHIA) program. Project goals for the future include digitizing the translated brochures, mounting them on the Houston HealthWays Website, and developing touch-screen kiosks. The CHIA group is investigating adding health resources in other Asian languages, as well as Spanish. Funding for this project has come from outside sources rather than from the regular library budget.

Detection and sequence analysis of a nickel-induced mutation in a retroviral model system

We have developed a novel way to assess the mutagenicity of environmentally important metal carcinogens, such as nickel, by creating a positive selection system based upon the conditional expression of a retroviral transforming gene. The target gene is the v-mos gene in MuSVts110, a murine retrovirus possessing a growth temperature dependent defect in expression of the transforming gene due to viral RNA splicing. In normal rat kidney cells infected with MuSVts110 (6m2 cells), splicing of the MuSVts110 RNA to form the mRNA from which the transforming protein, p85$\sp{\rm gag-mos}$, is translated is growth-temperature dependent, occurring at 33 C and below but not at 39 C and above. This splicing "defect" is mediated by cis-acting viral sequences. Nickel chloride treatment of 6m2 cells followed by growth at 39 C, allowed the selection of "revertant" cells which constitutively express p85$\sp{\rm gag-mos}$ due to stable changes in the viral RNA splicing phenotype, suggesting that nickel, a carcinogen whose mutagenicity has not been well established, could induce mutations in mammalian genes. We also show by direct sequencing of PCR-amplified integrated MuSVts110 DNA from a 6m2 nickel-revertant cell line that the nickel-induced mutation affecting the splicing phenotype is a cis-acting 70-base duplication of a region of the viral DNA surrounding the 3$\sp\prime$ splice site. These findings provide the first example of the molecular basis for a nickel-induced DNA lesion and establish the mutagenicity of this potent carcinogen. ^

Characteristics and experiences of past participants in the Texas Peer Assistance Program for Nurses

There are nearly 200,000 licensed practicing nurses in the state of Texas, representing one-tenth of the nations' workforce. The prevalence of substance abuse among nurses is estimated to range between six and 20 percent in this professional group.^ Since March 1987, the Texas Peer Assistance Program for Nurses (TPAPN) has offered intervention, education, support and monitoring to nurses in Texas whose practice has become impaired due to substance abuse and/or mental illness. Since then approximately 44 percent of nurses who voluntarily signed participation agreements successfully completed the program; fifty-six percent have not. One determinant of completion for those nurses identified as chemically dependent is abstinence from mood altering substances. Other helping professions report higher rates of abstinence two years following treatment.^ The purpose of this study was to investigate the relationship between relapse, demographics, treatment variables, work setting, "stress" indicators and support factors for nurses who participated in TPAPN. A questionnaire was mailed to 1000 randomly selected nurses who had signed agreements since 1987 and were no longer active in the program. More than 41% of the questionnaires were returned undeliverable.^ Recipients of the questionnaire were known only to TPAPN, never to the investigator. All information was received anonymously except when the participant chose to sign the questionnaire. A cover letter explaining the study and inviting participation was enclosed. Completion and return of the questionnaire was considered consent to participate.^ Findings demonstrated a significant relationship between relapse and opiates as the drug of choice for past participants in the Texas Peer Assistance Program for Nurses. Significant associations were found among factors such as control at work, support, physical complaints, job security, self-esteem and employment in this sample. Respondents shared copious written comments about their experiences in TPAPN. These data were analyzed using qualitative methods and compared with similar studies of recovering nurses. Further research with nurses whose practice has been affected by abuse of chemical and mental illness is warranted. ^

A comparative review of water disinfection methods appropriate for developing countries and their efficacy, cost-efficiency, and usability

Developing countries are heavily burdened by limited access to safe drinking water and subsequent water-related diseases. Numerous water treatment interventions combat this public health crisis, encompassing both traditional and less-common methods. Of these, water disinfection serves as an important means to provide safe drinking water. Existing literature discusses a wide range of traditional treatment options and encourages the use of multi-barrier approaches including coagulation-flocculation, filtration, and disinfection. Most sources do not delve into approaches specifically appropriate for developing countries, nor do they exclusively examine water disinfection methods.^ The objective of this review is to focus on an extensive range of chemical, physio-chemical, and physical water disinfection techniques to provide a compilation, description and evaluation of options available. Such an objective provides further understanding and knowledge to better inform water treatment interventions and explores alternate means of water disinfection appropriate for developing countries. Appropriateness for developing countries corresponds to the effectiveness of an available, easy to use disinfection technique at providing safe drinking water at a low cost.^ Among chemical disinfectants, SWS sodium hypochlorite solution is preferred over sodium hypochlorite bleach due to consistent concentrations. Tablet forms are highly recommended chemical disinfectants because they are effective and very easy to use, but also because they are stable. Examples include sodium dichloroisocyanurate, calcium hypochlorite, and chlorine dioxide, which vary in cost depending on location and availability. Among physio-chemical disinfection options, electrolysis which produces mixed oxidants (MIOX) provides a highly effective disinfection option with a higher upfront cost but very low cost over the long term. Among physical disinfection options, solar disinfection (SODIS) applications are effective, but they treat only a fixed volume of water at a time. They come with higher initial costs but very low on-going costs. Additional effective disinfection techniques may be suitable depending on the location, availability and cost.^
