Risks and issues for the health care worker in the human immunodeficiency virus era

Current strategies for managing providers infected with bloodborne pathogens

BACKGROUND

In 1991 the Centers for Disease Control and Prevention issued guidelines to reduce risks for provider-to-patient transmission of bloodborne pathogens. These guidelines, unchanged since 1991, recommend management strategies for hepatitis B e antigen-positive providers and for providers infected with human immunodeficiency virus; they do not address hepatitis C virus (HCV)-infected providers.

OBJECTIVE

We summarized current state practices and surveyed state health departments to determine (1) whether state policies have been modified since 1991; (2) whether state laws require prospective notification of patients and/or expert review panels to manage infected providers; (3) the frequency with which infected-providers issues come to the attention of state health departments; and (4) how state health departments intervene.

METHODS

We reviewed the 50 states' laws and guidelines to determine current practices and conducted a structured telephone survey of all state health departments.

RESULTS

Whereas only 19 states require infected providers to notify patients of the providers' bloodborne pathogen infection, these 19 states require notification under highly varied circumstances. Only 10 of 50 state health department officials identified these issues as requiring significant departmental effort. No state law or guideline incorporates information about providers' viral burdens as part of the risk assessment. Only 3 of 50 states have modified policies or laws since initial passage, and only 1 of 50 discusses the management of HCV-infected providers.

CONCLUSIONS

These results identify a need for incorporating contemporary scientific information into guidelines and also suggest that infected-provider issues are not occurring commonly, are not being detected, or are being managed at levels below the state health department.

Health care workers and AIDS: a differential study of beliefs and affects associated with accidental exposure to blood

This study aimed to analyze affective and cognitive determinants of the professional work of individuals caring for patients with HIV/AIDS, in view of the risk and/or experience of accidental exposure to blood. We drew on the theoretical-methodological references of Fishbein & Ajzen and Maslow's theory. Fifty health care workers were evaluated using an attitudes questionnaire and a needs and motivations instrument. The research verified differences between answers by health care workers who had never suffered accidents and those who had already experienced accidental exposure to blood. Health care workers did their work activities motivated by the need for self-fulfillment and valued their own performance when they were able to meet the patients' emotional needs. Among health professionals who had never experienced accidental exposure to blood, the predominant beliefs was that patients feel remorse over having expose themselves to HIV. Accidental exposure to blood raises difficulties in personal life. Technical aspects are also associated with the possibility of accidental exposure to blood.

A Review of Natural‐Rubber Latex Allergy in Health Care Workers

This brief review of natural-rubber latex (NRL) allergy in health care workers (HCWs) includes the definition of NRL allergy and data on its epidemiology, pathogenesis, diagnostic algorithm, management, long-term outcomes, economic impact, cost-effectiveness of changing facilities to a latex-free environment, and prevention. The data presented suggest that an individual with type I or type IV hypersensitivity to NRL should be able to continue to work in the workplace with careful evaluation and reasonable accommodations. Reducing exposure to latex is a safe and more economical alternative to complete removal of the individual from the place of employment. The use of low-allergen, nonpowdered NRL gloves substantially reduces airborne exposure to latex in most health care settings.

Phylogenetic analyses indicate an atypical nurse-to-patient transmission of human immunodeficiency virus type 1

A human immunodeficiency virus (HIV)-negative patient with no risk factor experienced HIV type 1 (HIV-1) primary infection 4 weeks after being hospitalized for surgery. Among the medical staff, only two night shift nurses were identified as HIV-1 seropositive. No exposure to blood was evidenced. To test the hypothesis of a possible nurse-to-patient transmission, phylogenetic analyses were conducted using two HIV-1 genomic regions (pol reverse transcriptase [RT] and env C2C4), each compared with reference strains and large local control sets (57 RT and 41 C2C4 local controls). Extensive analyses using multiple methodologies allowed us to test the robustness of phylogeny inference and to assess transmission hypotheses. Results allow us to unambiguously exclude one HIV-positive nurse and strongly suggest the other HIV-positive nurse as the source of infection of the patient.
