Long-term peritoneal dialysis before transplantation and intra-abdominal infection after simultaneous pancreas-kidney transplantations

OBJECTIVE: To examine the attitudes and knowledge of health care professionals regarding human immunodeficiency virus (HIV) infection in countries with a varying prevalence of HIV infection to assist in the development of acquired immunodeficiency syndrome (AIDS) educational programs. DESIGN: Anonymous questionnaire with four sections: demographics, attitudes, knowledge, and an open-ended question investigating feelings about the potential impact that HIV infection may have on respondents' practices. PARTICIPANTS: Final-year medical students, house staff, and attending physicians at teaching hospitals in India, Thailand, Canada, and the United States. RESULTS: From January to October 1992, 819 health care professionals completed the questionnaire: 340 from India, 196 from Canada, 155 from the United States, and 128 from Thailand. The percentage of respondents who had previous contact with patients with HIV/AIDS varied from 30% to 98%; it was lowest in India, followed by Thailand and then Canada, and highest in the United States. Percentages of respondents uncomfortable performing a physical examination on a patient with HIV/AIDS were 24%, 25%, 9%, and 4%, respectively. Mean HIV/AIDS knowledge scores were 83%, 84%, 92%, and 93%, respectively. Most respondents correctly identified modes of transmission of HIV infection. Only 67% of Indian health care professionals understood the concept of a false-negative screening serologic test, compared with 98% of Canadian health care professionals. In Canada and the United States, only 78% and 76%, respectively, understood the concept of a false-positive screening serologic test. Awareness of an asymptomatic stage of HIV infection ranged from 32% in India to 74% in Canada. Despite their concerns of becoming infected, health care professionals in countries with a lower prevalence of HIV infection reported a strong ethical duty to care for these patients. CONCLUSIONS: Level of comfort in caring for HIV-infected patients and HIV/AIDS knowledge scores varied directly with the amount of previous contact with these patients. Disturbing numbers of health care professionals from all four countries did not understand the potential problems of the enzyme-linked immunosorbent assay serologic test and a significant percentage were unaware of the asymptomatic stage of HIV infection. There is a universal need for increased education of health care professionals about HIV infection and AIDS.     

Congenital toxoplasmosis and seroconversion at the end of pregnancy: clinical observations

OBJECTIVE: To determine the knowledge of HIV-disease management and the adherence to contemporary guidelines among British Columbia physicians whose practices focused on HIV/AIDS. DESIGN: Self-administered mail survey. PARTICIPANTS: All 659 physicians registered in a province-wide HIV/AIDS drug treatment program. OUTCOME MEASURES: Data on demographic and personal characteristics of respondents, level of HIV-related experience, use of preventive vaccinations and tests, and preferred approaches to the prophylaxis and treatment of common opportunistic infections. Knowledge scores in 4 areas of patient care, as well as an overall score, were computed by comparing respondents' answers with the therapeutic strategies recommended at the time of the survey. Associations between physician characteristics and knowledge scores were identified by linear regression analysis. RESULTS: Of the 659 physicians surveyed, 65% returned responses: only 38% returned completed surveys while a further 27% returned a follow-up survey that asked nonrespondents about their demographic characteristics and HIV-related experience. Scores for specific areas of patient management ranged from 29% for the treatment of opportunistic infections to 62% for preventive measures, with a mean overall score of 47%. Physician knowledge in all areas of patient care was associated with the number of HIV-positive patients in the practice (p = 0.003 to p < 0.001). Physicians who were younger were more knowledgeable regarding preventive measures (p = 0.001); those whose practice location was in Vancouver had a greater knowledge of prophylaxis (p = 0.047); and those who had medical specialty training were more knowledgeable about the treatment of opportunistic infections (p = 0.009). CONCLUSIONS: There is substantial disparity in how physicians approach the management of HIV and related conditions. Deviations from therapeutic guidelines are common and may be associated with physician characteristics, particularly lack of experience in managing HIV.     

Prophylaxis after occupational exposure to human immunodeficiency virus (HIV)

Reasons for seeking consultation among health care workers due to potential or supposed risk of HIV infection were analyzed. From August 1990 till July 1996 41 health care providers were consulted including: 22 nurses, 1 student of nursing college, 3 midwives, 4 laboratory workers and 7 physicians (surgeons and gynaecologist). Type of exposure to HIV and applying of safety precautions were evaluated in each case. In 10 cases the offer of postexposure prophylaxis with zidovudine was accepted (6 nurses, 1 student of nursing college, 3 surgeons). Exposure to HIV was described as: needlestick immediately after it was used in a HIV/AIDS patient, injury with a surgical needle while operating on an HIV infected blood. In the remaining cases the fear of HIV infection was due to work without protective gloves (nurses, laboratory workers), performing surgery on HIV (+) patient, (surgeons, nurses) or short-time contact of HIV infected blood with undamaged skin (nurses). Following conclusions can be drawn from our study: 1. Health care workers undertake safety precautions only when they are informed about HIV seropositivity of the patient. 2. Patients whose HIV serologic status is not known are considered not to create health risk for medical staff. 3. The level of knowledge of health care workers about risk of acquiring HIV infection, lack of risk and ways of diminishing the risk is poor. 4. None of followed health care workers was HIV-seropositive after occupational exposure to HIV.     

The role of the general practitioner in the community care of people with HIV infection and AIDS: a comparative study of high- and low-prevalence areas in England

BACKGROUND: Policy for the care of people suffering from HIV and AIDS has changed over the past decade. Schemes for shared primary and secondary care have been met with varying success, and patients may be reluctant to become involved. No systematic evaluation comparing the views of primary care providers and users in areas of varying HIV prevalence has been published. AIM: To examine the role of general practice in areas of England with low and high human immunodeficiency virus (HIV) prevalence and to compare barriers to general practice care in each area. METHOD: We used focus groups, semistructured questionnaires and interviews in north London (high HIV prevalence) and Nottingham (low HIV prevalence). RESULTS: Four focus groups took place in London. A total of 411 general practitioners (GPs) in London and 405 in Nottingham replied to postal questionnaires. Overall, 121 primary care staff in 40 London practices and 26 staff in five Nottingham practices were interviewed. In all, 54 people infected with HIV were interviewed in London and 20 in Nottingham. Providers and users regarded the 24-hour availability and the familiar environment of general practice as its key assets. Lack of expertise and time were its disadvantages. Providers were concerned about inadequate communication with specialist services. Although providers were concerned about confidentiality, whether they had liberal and sympathetic attitudes was more important in deciding whether people with HIV used the service. In the low-prevalence area, general practice involvement was the result of individual initiatives, and practices were not integrated into specialist care. In the high-prevalence area, HIV care was more usual in general practice, but there was also little integration with HIV services. CONCLUSIONS: In high-prevalence districts, a strategy to make HIV care routine for all GPs may be appropriate. In low-prevalence areas, a network of selected, strategically located, relatively high-involvement practices may be more effective in meeting the primary care needs of people with HIV infection and acquired immunodeficiency syndrome (AIDS).     

Do physicians discuss HIV and AIDS with patients? A survey of physician practices

HIV and AIDS continue to be major concerns to the health care community and the world around them. Preventive efforts and education have been the focus of the fight against AIDS thus far. By the year 2000, 75% of physicians are expected to conduct risk-reduction counseling for patients regularly. Previous studies show that a smaller percentage "routinely" follow this recommendation. The purpose of our study was to assess with what percentage of patients physicians discuss several HIV/ AIDS-related topics, what percentage of their patients are considered at risk for infection, and how comfortable the physicians are with their knowledge level and discussing the subject matter. We sent surveys to the last five graduating classes from St. Louis University School of Medicine and to 169 physician preceptors in the community. The survey asked about patients considered at risk, physician comfort level with HIV/ AIDS, the percentage of patients they discuss various HIV/AIDS topics with, and his or her preparedness for these discussions. Total responses were 464 (53.7%) representing all areas of medicine. Most of the physicians (72.9%) consider 0-25% of their patients at risk for HIV/AIDS. Eighty-one percent claim they are moderately or very comfortable discussing the material with patients and more than 90% feel they have at least adequate knowledge. Most of the respondents discuss the HIV/ AIDS topics with 0-25% of patients. Recent medical school graduates and primary care physicians are more comfortable with HIV/AIDS and discuss the surveyed topics with a higher percentage of patients.     

The role of reactive nitrogen intermediates in modulation of gametocyte infectivity of rodent malaria parasites

Two hundred and fourteen young women received acquired immunodeficiency syndrome (AIDS) prevention interventions at an inner-city family health center serving minority patients predominantly. The community in which the health center is located has a high incidence of intravenous (IV) drug abuse. Either a peer or a health care provider delivered the intervention. In the peer-delivered intervention, a trained peer educator reviewed with patients an AIDS "Rap" videotape and several AIDS brochures, which imparted information about human immunodeficiency virus (HIV), its transmission, and prevention. In the provider-delivered intervention, family practice residents, attending physicians, and nurse practitioners used a patient-centered counseling approach to convey the same information. Questionnaires administered immediately before and after the intervention and at one month follow-up evaluated changes in knowledge, attitudes, and behavior. Analyses of data from both combined intervention groups revealed significant improvements in several areas of knowledge, including the effectiveness of using a condom and cleaning IV drug implements with bleach to prevent transmission of HIV. Many improvements were retained at the one-month follow-up. In addition, subjects in both groups who were sexually active stated immediately after the intervention that asking a sexual partner about past sexual experience would now be less difficult, and at one-month follow-up they reported a significant decrease in the frequency of vaginal sex. Our findings suggest that counseling by physicians can achieve more changes in knowledge of sexual risks, whereas peer education can achieve greater changes in knowledge about IV drug use. Results show that both approaches to AIDS prevention used in this study can significantly affect knowledge, attitudes, and sexual behavior.     

Technique for direct and quantitative evaluation of erythrocyte aggregability in blood samples

A group of young people ages 10 to 18, interviewed after basketball star Earvin "Magic" Johnson announced that he had tested positive for the human immunodeficiency virus (HIV), were asked for their reactions to the news. Their knowledge of and attitudes regarding AIDS were also compared to those of similar young people interviewed before the announcement. Reactions to the announcement were varied and were accompanied by only isolated changes in knowledge and attitudes, suggesting that news of this celebrity's HIV infection served primarily to reinforce or make temporarily more salient knowledge and attitudes that predated the announcement.     

Planning and evaluating strategies for AIDS health education interventions in the Muslim community in Uganda

In 1992 the Islamic Medical Association of Uganda designed an AIDS prevention project. A baseline survey was conducted to assess prevailing knowledge, attitudes, and practices among the Muslim communities in two districts. A low rate of incorrect beliefs about HIV transmission was found, although gaps in knowledge remain, particularly regarding vertical transmission and asymptomatic HIV infection. Less than 10% knew that condoms can protect against HIV transmission. Lack of knowledge was documented regarding the risk of HIV transmission associated with practices common in the Islamic community, such as polygamous marriages, circumcision, and ablution of the dead. The AIDS prevention project has incorporated specific messages and interventions as a result of these findings.     

Cost of care for patients with human immunodeficiency virus infection. Patterns of utilization and charges in a public health care system

BACKGROUND: The increasing impact of human immunodeficiency virus (HIV) infection on the health care delivery system requires surveillance of current patterns of HIV-related health care utilization to adequately plan for future needs. Most studies to date have concentrated on inpatient care for patients with the acquired immunodeficiency syndrome (AIDS). Outpatient utilization has been less well studied and there are few data regarding HIV-infected patients without a diagnosis of AIDS. METHODS: Denver Health and Hospitals is a public system delivering comprehensive health care to mostly indigent residents of the city and county of Denver. Patients with HIV infection in this system were identified through multiple surveillance sources, and billing system records for these patients were analyzed. RESULTS: During 1990, 812 patients with HIV infection of 13 years or more were accessed in the Denver Health and Hospitals. During that year, the total HIV-related health care charges were $7,858,690, of which 57% were for inpatient care and 43% for ambulatory care. Patients with AIDS (34% of patients) accounted for 62% of all charges, and patients with HIV infection but without a diagnosis of AIDS (66% of patients) for 38% of charges. Compared with national predictions, patients with AIDS in our system had lower inpatient and higher outpatient utilization. CONCLUSIONS: These results are consistent with a shift from inpatient to outpatient health care services in patients with AIDS. A significant proportion of HIV-related health care costs are incurred by patients who have not yet developed AIDS.     

AIDS education in Tanzania: promoting risk reduction among primary school children

OBJECTIVES: The purpose of this study was to test the effects of an education program in Tanzania designed to reduce children's risk of human immunodeficiency virus (HIV) infection and to improve their tolerance of and care for people with acquired immunodeficiency syndrome (AIDS). METHODS: A randomized controlled community trial including baseline and 12-month follow-up surveys was employed. Public primary schools in the Arusha and Kilimanjaro regions of Tanzania were stratified according to location and randomly assigned to intervention (n = 6) or comparison (n = 12) conditions. Of the 1063 sixth-grade students (average age: 13.6 years) who participated at baseline, 814 participated in the follow-up survey. RESULTS: At follow-up, statistically significant effects favoring the intervention group were observed for exposure to AIDS information and communication, AIDS knowledge, attitudes toward people with AIDS, and subjective norms and behavioral intentions toward having sexual intercourse. A consistent positive but nonsignificant trend was seen for attitudes toward having sexual intercourse and for initiation of sexual intercourse during the previous year (7% vs 17%). CONCLUSIONS: It is feasible and effective to train local teachers and health workers to provide HIV/AIDS education to Tanzanian primary school children.     

A survey of psychologists' education, knowledge, and experience treating clients with HIV/AIDS.

Practicing psychologists are providing services to persons with HIV infection and those at-risk for AIDS. However, most practitioners have not received formal training about HIV/AIDS. In this study, the majority of psychologists surveyed had treated persons at-risk for the virus but had not received HIV/AIDS information in formal educational programs. Most respondents obtained knowledge through popular media. There is a growing body of specialized knowledge about HIV/AIDS for mental health professionals. In addition to better serving HIV-infected clients, psychologists with current multidisciplinary HIV/AIDS knowledge will be valuable members of health care teams.

Prognostic value of dipyridamole thallium-201 screening to minimize perioperative cardiac complications in diabetics undergoing kidney or kidney-pancreas transplantation

A survey of knowledge, attitude and practice (KAP) regarding human immunodeficiency virus infection was performed on 899 students from 3 government-administered high schools located in the Bangkok Metropolitan area. Initially, all students completed a written questionnaire (pre-test) regarding HIV/AIDS. Following this, they attended a slide lecture presentation given by a specialist physician. The same test questionnaire was then completed by the same students six weeks (post-test) later for comparison of their previous KAP. The subjects composed of male to female ratio equal to that of the median age 15-16 years old. Sixty-seven per cent of the subjects were living with their parents, 16.3 per cent with relatives and 15 per cent with friends. Ninety nine per cent of the subjects had received information on HIV/AIDS before enrollment to this study. The source of knowledge ranged from television (89.1%), teachers (81.6%), pamphlets (80.2%), newspapers (75%), radio (55%), health care workers (53.4%), friends (38.6%) and only 32.5 per cent from their parents. The subjects' knowledge about HIV/AIDS and risk factors in the post-test questionnaire was significantly increased (P < 0.001) from the pre-test status. However, their attitudes to an HIV infected person were not significantly changed in the post-test questionnaire: only the "attending school" question showed significantly (P < 0.05) increased numbers of agreement. Similarly, the attitudes and practices to prevent HIV infection were not significantly (P > 0.05) different between pre-test and post-test questionnaires. The result of this study is to recommend regular school-based programs of education to increase awareness of preventive strategies for HIV/AIDS and sexually transmitted diseases.     

Rural school nurses' attitudes about AIDS and homosexuality

The AIDS epidemic has spread to rural areas of the United States. Conservative rural communities are facing the challenge of having children with HIV entering school. School nurses, as the only health care providers in the schools, are in a strong position to facilitate the education of children with HIV and to provide AIDS education to students, faculty, and parents. School nurses' knowledge and attitudes about AIDS and people with AIDS influence their effectiveness in prevention activities and care of HIV-infected children. This study examined the relationship between specific demographic, practice, and cultural variables and rural school nurses' attitudes about AIDS and homosexuality. Sixty-nine school nurses responded to a mailed questionnaire as part of a larger study of rural nurses. Results indicate attitudes about homosexuality were related to nurses' homosexual knowledge and religious beliefs while attitudes about AIDS were related to nurses' willingness to care for people with AIDS and feeling prepared to do so.     

AIDS-related knowledge and sex behavior: a review of Italian studies of young people

To plan further AIDS health promotion programmes information is needed about knowledge and attitudes relating to HIV infection among the general public. This article reviews the results of Italian studies conducted from 1990 to 1994 on young's knowledge and behaviour related to HIV infection. Eighteen studies were identified. The results show a good level of knowledge of the means of transmitting the virus, but suggest that the information does not necessarily involve a change in attitude and behaviour.     

HIV prevention for youths in independent living programs: expanding life options

The incidence of human immunodeficiency virus (HIV) infection among adolescents is increasing. Youths who were abused and neglected and in out-of-home care are among those at highest risk of acquiring HIV. The concurrence of sexual activity and school failures contributes to their high-risk status. Research suggests that changing behaviors of troubled youths requires programs that not only include HIV-related knowledge, attitudes, and skills, but also incentives and skills for educational planning that will expand the future life options of these youths.     

Energetic cost of hovering flight in a nectar-feeding bat measured with fast-response respirometry

BACKGROUND: Given the high occurrence of oral manifestations in patients infected with human immunodeficiency virus (HIV), the relative ease in recognizing these manifestations on physical examination, and their potential impact on the health care and quality of life in these patients, it is critical to provide adequate training for primary care physicians in this area. METHODS: Based on a review of the published literature and the consensus of a national panel of primary care physicians and dentists with clinical and research expertise in this area, a core curriculum was developed for primary care physicians regarding oral health care issues in HIV disease. RESULTS AND CONCLUSIONS: We describe the process of developing the core curriculum of knowledge, skills, and attitudes regarding oral health care issues in HIV disease. The final curriculum is in a format that allows for easy accessibility and is organized in a manner that is clinically relevant for primary care physicians.     

Attitudes of medical students to HIV and AIDS

OBJECTIVE--To assess the knowledge and attitudes of medical students to HIV/AIDS and whether attitudes correlate with knowledge and clinical experience. To determine if students felt adequately prepared to deal with medical and psychological aspects of HIV/AIDS. SUBJECTS AND METHODS--The subjects consisted of 190 London and 99 Cambridge medical students at the end of their genitourinary medicine attachment, plus 230 Cambridge medical students at the end of their second pre-clinical year. Between March 1991 and February 1992 all were asked to complete an anonymous questionnaire, covering factual knowledge and attitudes towards HIV/AIDS. MAIN RESULTS--Cambridge genitourinary medicine students, despite spending less time studying HIV infection than their London counterparts gave more correct answers to the factual questions, although this difference did not reach significance (52.4% vs. 47.5%, p = 0.14). One third of students believed that many health care workers were at high risk of acquiring HIV at work and one fifth thought doctors should have the right to refuse to treat people with HIV. Fourteen percent of Cambridge genitourinary medicine students indicated that most British people with HIV have only themselves to blame, by comparison with 4% of London students (p = 0.003). Thirty-nine per cent of Cambridge genitourinary medicine students expressed reluctance to care for someone with AIDS by comparison with 10% of London students (p = 0.0001). CONCLUSIONS--It is important that medical educators convey accurate information about HIV, including the actual risks posed by occupational exposure and try to ensure that medical students spend sufficient time seeing patients with HIV/AIDS during their training.     

Compliance with infection-control procedures and attitudes of oral health care providers toward patients with HIV/AIDS: a synthesis of the literature

Many publications on the knowledge, practice, and attitudes of oral health care providers can be found in the literature. This paper is a synthesis of literature on their compliance with infection-control procedures and their attitudes toward patients with HIV/AIDS. The literature indicates increased compliance with infection-control procedures. While some oral health care providers report negative attitudes toward treating patients with HIV/AIDS, their fear is decreasing, possibly due to their increased compliance with infection-control procedures and increased access to care for those with HIV/AIDS.     

Attitude and structural barriers detected in primary care physicians towards treating patients with HIV/AIDS infection

OBJECTIVES: To identify attitudes, knowledge and self-perceived risks among doctors in the Este-Oriente District of Sevilla concerning HIV/AIDS infection; to detect attitude problems and structural barriers affecting doctors' predisposition towards patients with HIV/AIDS infection. DESIGN: A cross sectional study using a self-administered questionnaire. SETTING: Este-Oriente Primary Care district, Sevilla. PARTICIPANTS: Permanent and provisional doctors and paediatricians working in the district during the survey. MEASUREMENTS AND RESULTS: Reply rate was 86% (n = 111). Most doctors (85%) had treated one or more patients with HIV. 91% thought they had to treat these persons. However, 21% would not work with them, if they had the choice. CONCLUSIONS: Attitudes of doctors and paediatricians in the Este-Oriente district of Sevilla towards HIV/AIDS patients can be qualified as positive. Most doctors need to extend their knowledge of this disease. The perception of risk of contagion is high and higher than the real risk. Important attitude and structural barriers to care provision were detected: intervention strategies were proposed by the doctors and paediatricians of this district.     

Pharmacological distribution diagrams: a tool for de novo drug design

BACKGROUND: There is no empirical data available on attitudes concerning AIDS and habits towards HIV infected patients of physicians in general or private practice. In this study results of a self-evaluation are presented. METHODS: 178 physicians working with out-patients in different medical fields were randomly selected for a cross sectional study and interviewed using a standardised questionnaire. RESULTS: 89% think that they are sufficiently informed about AIDS (in the USA 20%). They regarded the risk of infection to be lower than the Anglo-American physicians. They believed there is a lack of interchange of information between colleagues regarding the degree of infectiousness of referred patients. A third of the physicians fear that other patients will go elsewhere if they find out that their physician is treating AIDS patients. 54% would hold special clinic sessions for HIV-patients outside the normal schedule for practice times. 89% believed that HIV patients were partly to blame for their illness. CONCLUSIONS: Although the physicians recognise the problem of HIV-infection, they partly deny the real necessities and facts. A reason for this could be the emotions underlying the general attitude to everything pertaining to HIV-disease. Attitudes to HIV-disease and the dealing with it in daily practice must be considered on the basis of individual emotional motives.
