Does dissatisfaction with health plans stem from having no choices?

Data from a 1997 nationwide telephone survey are used to assess the relationship between choice and public opinion about managed care. We found that only a minority of the working-age population effectively control what health plan they get. Persons without choice were markedly more dissatisfied with their health plan, especially when enrolled in managed care. In multivariate analysis, how respondents rated their health plan depended as much on whether they lacked choice as on whether they were enrolled in managed care. Persons without choice also had more negative opinions about managed care in general. The results suggest that the managed care "backlash" may persist so long as consumers have little control over health insurance decisions.     

Infection control in the dental practice with emphasis on the orthodontic practice

Infections present a significant hazard in the orthodontic office because they can be transmitted by blood or saliva through direct or indirect contact, droplets, aerosols, or contaminated instruments and equipment. Because the incidence of certain microbial cross-infections in the dental environment has not been well documented, orthodontic personnel may not take the problem of cross-infection as seriously as they should, and they may transmit or contract more infections than they realize. The use of effective infection-control procedures in the orthodontic office and laboratory will prevent cross-contamination that may extend to the orthodontist, office staff, assistants, and patients. The goal of this article is to present infection control in a simple, yet comprehensive, manner, and to encourage all orthodontic practitioners to implement essential infection-control procedures in their practices.

Employee reactions to a pay incentive plan.

Examined productivity records, personnel data, and attitudinal data obtained from (a) a group of workers with an incentive plan felt to be successful by management and (b) a group in a different plant with similar jobs but with an unsuccessful incentive plan. All workers were family men, had jobs involving unskilled manual labor, and all had high seniority. An analysis of the employees' attitudes showed that they trusted management, understood the plan, and saw a close relationship between their pay and their performance. Based upon expectancy theory, it was hypothesized that because these conditions existed, the workers would respond directly to the economic payoff structure of the plan. To test this hypothesis, a mathematical model was developed to predict the productivity of the work group. The data show a high degree of fit between the model's predictions and the actual productivity of the group. The implications of this for future research and for the design of incentive systems are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Wound closure of the fallopian tube with fibrin glue: endoscopic organ preserving therapy of extrauterine pregnancy

Families in transition (FIT), a joint program between Beth Israel Medical Center (BIMC) and National Development and Research Institutes, Inc., uses indigenous neighborhood women, Compa?eras (companions), to conduct street outreach in a New York City neighborhood where HIV infection is rampant. The outreach workers inform people that, not only will they be assisted in talking about HIV and guardianship for their children, but that they will be provided information concerning access to food stamps, housing, health care, and other basic needs. Through community participation, the Compa?eras empower themselves through knowledge making and sharing and, in the process, create conditions in which other women can began to effect changes in their individual lives and families. The ultimate goal of the project is to support HIV-infected women in finding their voices so that they can talk with their children and plan for their futures.     

Teaching low achievers and students with learning disabilities to plan, write, and revise opinion essays

A total of 38 problem learners comprising adolescents with learning disabilities and low achievers participated in this study. Of these, 20 were untrained control participants; the remainder were trained to plan, write, and revise opinion essays. Trainees were randomly divided into pairs and taught to collaboratively use interactive dialogues to plan and revise their essays (but they wrote their essays separately). The results from multivariate analyses of variance (MANOVAs) and effect sizes indicated that trainees improved significantly from pretest to posttest in clarity and cogency of written opinion essays, and maintained such gains. Additional analyses indicated that they surpassed the untrained control group. Questionnaire data indicated trainees improved in self-efficacy of writing only. The same finding held true in comparison with untrained participants. The discussion integrates the trainees' performance data with the questionnaire data and considers the research implications and limitations of the study.     

Managing occupational HIV exposures: a Canadian study

The findings reported in this paper are part of a larger study that explored how nurses cope with the risk of acquiring HIV infection while caring for persons with AIDS (PWAs). The data were collected through in-depth interviews with 13 nurses who cared for PWAs in a large Western Canadian hospital. Seven of these nurses perceived that they had been exposed to HIV-infected blood or body fluids. This paper describes how these seven nurses coped with actual exposures to HIV-infected blood or body fluids. Data were analyzed using the methodology of grounded theory. Nurses' coping efforts after exposure were grouped into four categories: minimizing the effect of exposures, reducing a sense of vulnerability, selective disclosure to others, and assigning meaning. Nurses minimized the physical effects of exposure through measures such as 'bleeding' the needlestick injury and immersing the affected area in bleach solution. Nurses reduced their sense of vulnerability by assessing the possibility of harm, avoiding situations that aroused fear, and confronting the decision for HIV testing. Nurses limited their disclosures to co-workers to avoid rejection and to preserve professional self-esteem. Disclousre to significant others was influenced primarily by the support nurses perceived they would receive. Finally, nurses attempted to assign meaning to the exposure by determining why the event occurred and by evaluating the implications it has had on their lives. The article concludes with implications for nursing practice.     

From the desert: transcultural aspects of cancer nursing care in Israel

BACKGROUND: Medical students may be at high risk for occupational exposures to blood. OBJECTIVE: To measure the frequency of medical students' exposure to infectious body substances, to identify factors that affect the probability of such exposure, and to suggest targets for the prevention of such exposure. DESIGN: Review of all exposures reported by medical students at the University of California, San Francisco, School of Medicine. SETTING: Teaching hospitals affiliated with the University of California, San Francisco. PARTICIPANTS: Third- and fourth-year medical students from the classes of 1990 through 1996 at the University of California, San Francisco, School of Medicine. INTERVENTIONS: A needlestick hotline service was instituted at teaching hospitals affiliated with the University of California, San Francisco, and a required course was created to train students in universal precautions and clinical skills before the beginning of the third-year clerkship. MEASUREMENTS: Reports of exposures made to the needlestick hotline service, including type of exposure, training site, clerkship, and time of year. RESULTS: 119 of 1022 medical students sustained 129 exposures. Of these exposures, 82% occurred on four services: obstetrics-gynecology, surgery, medicine, and emergency medicine. The probability of exposure was not related to graduation year, clerkship location, previous clerkship experience, or training site. Surveys of two graduating classes at the beginning and end of the study showed that the percentage of exposures reported increased from 45% to 65% over the 7-year study period. Thus, the reported injury rates represent minimum estimates of actual occurrences. Human immunodeficiency virus infection and hepatitis were not reported, although follow-up was limited. CONCLUSIONS: Instruction in universal precautions and clinical procedures is not sufficient to prevent exposures to blood during medical training. Medical schools must assume greater responsibility for ensuring that students are proficient in the safe conduct of clinical procedures and must develop systems that protect students so that they can report and learn from their mistakes.     

Basics of surveillance--an overview

Surveillance of nosocomial infections is the foundation of an infection control program. This article describes components of a surveillance system, methods for surveillance, methods for case-finding, and data sources. We encourage the epidemiology team to use this background information as they design surveillance systems that meet the goals of their individual institution's infection control program.     

Disseminated acanthamoeba infection in patients with AIDS: case reports and review

Acanthamoeba infection has been described as an opportunistic infection in persons with AIDS. We report two cases of patients with AIDS and acanthamoeba infection and review the manifestations of this protozoan infection in patients infected with human immunodeficiency virus. The diagnosis of this infection requires a high index of suspicion because the clinical and histologic manifestations may be confused with those of disseminated fungal or algal disease. Clinicians and laboratory personnel should be aware of this potentially fatal condition so that appropriate diagnostic studies can be performed and treatment can be urgently administered. Early initiation of therapy may alter the clinical outcome of the disease.     

The asymptomatic HB6-Ag carrier: auto- and heterologous perils

The asympatomatic carrier--usually discovered on offering to be a blood donor--presents a complex health problem which to date has received only "guarded" attention. These carriers may be dangerous, because they can transmit the HBs-Ag not only by parenteral but also by "nonparenteral" means, due to its presence in urine, feces, saliva, tears, semen, vaginal discharge, menstrual flow, breast milk, joint, ascitic and cerebrospinal fluids. The transmission by sexual contact is well established. Inapparent transmission may also occur from insufficient sterilization of instruments, by tatooing, ear piercing, by barbers, manicurists, dentists and by mosquitoes and bedbugs. Some of the characteristics of an asymptomatic HBs-Ag carrier seem to be: a young male, most often black, from a poor social and hygienic environment with a possible gene dependent immune deficiency state. Our experiences suggest that all newly admitted patients to the hospital personnel should have determinations of the presence of HBs-Ag in their blood, so that adequate steps can be taken to protect their contacts from infection.     

Prevention of nosocomial transmission of Mycobacterium tuberculosis

The recent resurgence of TB together with the ongoing HIV epidemic has resulted in a larger number of infectious TB patients being admitted to US health care facilities. These patients have become a source for both nosocomial (patient-to-patient) and occupational (patient-to-health care worker) M. tuberculosis transmission. Infectious MDR-TB patients serve as even greater potential infectious sources because they often remain AFB smear and culture positive for months to years. The keys to the prevention of nosocomial and occupational transmission of M. tuberculosis is conducting a risk assessment for each area of the facility and instituting appropriate control measures, having a high index of suspicion by clinicians for infectious TB in those who present with consistent signs and symptoms, rapid triage of such patients to isolation areas and their appropriate clinical work-up, and the institution of effective antituberculous therapy. Infection control personnel should ensure that infectious TB patients are isolated in appropriate isolation rooms (i.e., negative pressure, greater than or equal to 6 ACH, and direct external exhaust of the room air). Health care workers with infectious TB patient contact should be instructed in the epidemiology of M. tuberculosis transmission, the role of respirators in protecting the health care worker from airborne inoculation, and the importance of periodic health care worker TST. The nosocomial TB outbreaks in the 1980s and 1990s document that M. tuberculosis can be transmitted to both patients and health care workers in US health care facilities when appropriate infection control measures are not fully implemented. Follow-up studies at some of these institutions, however, document that when infection control measures similar to the 1990 or 1994 CDC TB Guidelines are fully implemented, M. tuberculosis transmission to both patients and health care workers can be reduced or eliminated. Protection of both patients and health care workers from M. tuberculosis infection is dependent on an understanding and full implementation of the 1994 CDC TB Guidelines.     

The science and politics of race-norming.

Disparate impact (racial imbalance) in employee selection constitutes prima facie evidence of unlawful discrimination. Research in personnel psychology has shown, however, that valid and unbiased selection procedures often guarantee disparate impact and that they will continue to do so as long as there remain large racial disparities in job-related skills and abilities. Employers are in a legal bind because often they can avoid disparate impact only by engaging in unlawful disparate treatment (racial preferences). Some personnel psychologists have argued that there is scientific justification for race-based adjustments in test scores that eliminate disparate impact. Analyses of their seemingly scientific reasoning illustrate how personnel selection science is being compromised in an effort to reconcile contradictory legal demands.

Cost-effectiveness of regional poison control centers

BACKGROUND: Poison exposures are a significant public health concern. Despite the impact that regional poison control centers have on reducing morbidity and mortality associated with poison exposures, they are facing a serious financial crisis today resulting in an increased emphasis on their economic justification. METHODS: Using decision-analysis techniques, the cost-effectiveness of the treatment of poison exposures with the services of a regional poison control center compared with treatment without access to any poison control center was evaluated. The relative cost-effectiveness was modeled based on 2 outcomes (morbidity and mortality) for each of 4 typical poison exposures. Additionally, analyses were conducted to test the sensitivity of the cost-effectiveness ratios to outcome probability, average inpatient and emergency department costs, and proportion of poison exposures treated on site by the regional poison control center. A societal perspective was adopted. RESULTS: The regional poison control center was substantially more cost-effective than the treatment of poison exposures without the services of a regional poison control center for both outcomes (morbidity and mortality) in each of the poison exposures considered. The results of the sensitivity analyses demonstrated that the outcomes of the decision analyses do not change regardless of the type of poison exposure, outcome considered, clinical outcome probabilities, average inpatient and emergency department costs, and proportion of poison-exposure cases treated on site by a regional poison control center. CONCLUSIONS: The regional poison control center is consistently more cost-effective in the treatment of poison exposures with an average cost-effectiveness ratio (cost per successful outcome) approximately half of that achieved without the services of a regional poison control center. Finally, significant cost savings to society are realized for each additional successful outcome obtained with a regional poison control center.     

Disability and the law of employment

The present estimate of global mortality caused by cardiovascular diseases is accompanied by a considerable degree of uncertainty, which, in so far as monitoring their emergence in developing countries is concerned, undoubtedly represents one of the major obstacles to effective public health interventions for their control. In much of the developing world, vital registration data are lacking and it would be unreasonable to expect rapid progress in the recording of causes of death because resources are so limited. The most promising avenue is that of the progressive implementation of clearly defined mortality surveillance systems that cover all deaths and permit the attribution of probable causes via lay reporting. The reliability of the data largely depends on the specificity and clarity of the verbal autopsy algorithm employed and on the availability of medically trained personnel to validate the returns.     

Tuberculosis control in health care workers: an algorithmic approach

Health care workers have always been at risk for contracting tuberculosis (TB) from patients with active disease. In addition, health care workers who have active TB pose a risk for transmitting TB to patients. As a result, institutions that employ health care professionals must adopt programs to reduce the probability of transmission of TB to their employees or their patients. This article discusses the new guidelines for preventing TB issued by the Centers for Disease Control and Prevention and suggests approaches for adapting the guidelines to the needs of individual institutions. It emphasizes the importance of skin testing for early detection, correct interpretation of the tests, the approaches to determining who should be tested, and the relative frequency with which employees should be tested. It presents algorithms to assist employee health and infection control personnel in screening current and prospective employees, and in responding to positive and negative test results, and the booster effect.     

Surgical blood exposures after the OSHA bloodborne pathogens standard: frequency and prevention

1. Approximately 22.4 million surgical procedures are performed annually in US hospitals. Up to 2,688,000 personnel exposures to blood may occur annually. Punctures would account for 349,940 (13%) of those exposures, and 38,493 patients would have contact with blood from the punctured personnel. 2. Epidemiologists use parameters of time, place, and person to describe situations and identify prevention strategies: who is at increased risk, what devices and activities lead to more frequent exposures, when exposure frequency is greatest, and where blood contact actually occurs. The answers to these questions form the basis for successful prevention; without the correct answers operating rooms either miss the target or spend far too much money preventing low-risk events. 3. OSHA and previous researchers estimated that a substantial portion of blood exposures could be prevented by either changing certain practices such as passing loaded suture holders, or by protective attire such as fluid-resistant gowns.     

Herpes management and prophylaxis

In summary, clinical management of HSV infection depends on an individual having an appropriate diagnosis and receiving proper counseling, follow-up of both themselves and their sexual partners, as well as having an opportunity to discuss with more knowledgeable physicians, the options for antiviral management should their individual problems and sequelae of genital HSV infection require it. Although some of the aspects of management such as HSV type 2 serology testing or continuous antiviral therapy will be limited in their availability to individuals worldwide because of cost, it is possible to improve knowledge among physicians about diagnosis. Furthermore, it is necessary to ensure that facilities for patient information and counselling are available. These latter facilities are often provided extremely efficiently by self-help or voluntary groups so it is vital that physicians understand and ensure that they obtain details of such groups to pass on to their patients.     

MAP2, synaptophysin immunostaining in rat brain and behavioral modifications after cerebral postischemic reperfusion

Infection rates are important markers for clinical quality assurance. For internal control, they may only be used under the condition of homogeneous data collection and evaluation according to identical standard operating procedures during the entire investigation period. For inter-hospital comparison, they may only be used if additionally the observed patient groups are well defined and comparable. A survey of the infection rates published during the last 6 years in the German traumatological literature (n = 71) indeed shows (concerning series later than 1985) similar infection rates for procedures in less and in more problematic anatomical regions and in clean and contaminated situations of about 2-3%, after open injuries sporadically max. 10%. Finally, it is demonstrated that conclusions concerning a general "risk of infection" based on infection rates for specific surgical procedures are not possible and vice versa. We strongly recommend the future application of a standardized definition of wound infection. The differentiation between deep and superficial infection should be abandoned. For all mentioned "infection rates" it should be indicated whether it is with reference to the risk of infection of a specific procedure or only a general statement.     

Quality of care of patients with diabetic foot problems in Barbados

In Barbados diabetics with foot problems account for 80% of the patients in the female and 50% of those in the male general surgery wards, and many patients have major amputations for preventable problems. A six month prospective study was undertaken of all cases admitted with foot problems to the general surgical wards of the Queen Elizabeth Hospital (QEH) in order to determine the quality of foot care, particularly among diabetics. 67.5% of the 195 patients (55% female) admitted to the study were diabetic, most of whom were diagnosed 10 to 19 years previously. Most of the patients were 70 to 80 years old, but significantly more diabetics than non-diabetics were 40 to 70 years old. Foot problems in diabetics were precipitated by events that are considered trivial in non-diabetic patients. 87 (58%) of 150 responding patients had their feet inspected by health personnel in the previous year. 47 (63.5%) of the 74 who responded about the care of their nails said that they took care of their nails themselves. Nearly 40% of diabetic and non-diabetic patients had no reported source of care before their admission. 14 patients (10 diabetic) sought care the same day and 11 (nine diabetics) the day after noticing foot problems. Most patients presented with infection as part of their problem; recognition of the early signs of infection should be an integral part of the education of the diabetic patient. Educational efforts for patients must be continually reinforced because many patients said they had had no education about the care of their feet in the previous year.
