International Perspective: RURAL NURSING IN THE UNITED STATES: WHERE DO WE STAND AS WE ENTER A NEW MILLENNIUM?
Approximately one-fourth of all Americans live in rural communities; and, of the 50 States, 31 have more than 60% of their counties designated as rural. No matter what indicator is used, United States residents in non-metropolitan areas have less than metropolitan counterparts (e.g. per capita income, health status, access to care, level of education and employment opportunities) and are more likely to need help from human services and health professionals. Additionally, rural people often must confront unique obstacles not experienced by most urban residents to access those services. As nurses live and work in rural communities they, too, must be aware of and contend with similar factors in their practice settings. In some ways rural nursing practice has changed dramatically over the last decade but in other ways things remain much the same. This article will examine common nursing issues associated with caring for clients in a rural environment. The information in this article is based on a review of the literature and the author\u27s personal and professional nursing experiences
Accurate diagnosis of latent tuberculosis in children, people who are immunocompromised or at risk from immunosuppression and recent arrivals from countries with a high incidence of tuberculosis: systematic review and economic evaluation
Background - Tuberculosis (TB), caused by Mycobacterium tuberculosis (MTB) [(Zopf 1883) Lehmann and Neumann 1896], is a major cause of morbidity and mortality. Nearly one-third of the world’s population is infected with MTB; TB has an annual incidence of 9 million new cases and each year causes 2 million deaths worldwide.
Objectives - To investigate the clinical effectiveness and cost-effectiveness of screening tests [interferon-gamma release assays (IGRAs) and tuberculin skin tests (TSTs)] in latent tuberculosis infection (LTBI) diagnosis to support National Institute for Health and Care Excellence (NICE) guideline development for three population groups: children, immunocompromised people and those who have recently arrived in the UK from high-incidence countries. All of these groups are at higher risk of progression from LTBI to active TB.
Results - In total, 6687 records were screened, of which 53 unique studies were included (a further 37 studies were identified from a previous NICE guideline). The majority of the included studies compared the strength of association for the QFT-GIT/G IGRA with the TST (5 mm or 10 mm) in relation to the incidence of active TB or previous TB exposure. Ten studies reported evidence on decision-analytic models to determine the cost-effectiveness of IGRAs compared with the TST for LTBI diagnosis. In children, TST (≥ 5 mm) negative followed by QFT-GIT was the most cost-effective strategy, with an incremental cost-effectiveness ratio (ICER) of £18,900 per quality-adjusted life-year (QALY) gained. In immunocompromised people, QFT-GIT negative followed by the TST (≥ 5 mm) was the most cost-effective strategy, with an ICER of approximately £18,700 per QALY gained. In those recently arrived from high TB incidence countries, the TST (≥ 5 mm) alone was less costly and more effective than TST (≥ 5 mm) positive followed by QFT-GIT or T-SPOT.TB or QFT-GIT alone.
Conclusions - Given the current evidence, TST (≥ 5 mm) negative followed by QFT-GIT for children, QFT-GIT negative followed by TST (≥ 5 mm) for the immunocompromised population and TST (≥ 5 mm) for recent arrivals were the most cost-effective strategies for diagnosing LTBI that progresses to active TB. These results should be interpreted with caution given the limitations identified. The evidence available is limited and more high-quality research in this area is needed including studies on the inconsistent performance of tests in high-compared with low-incidence TB settings; the prospective assessment of progression to active TB for those at high risk; the relative benefits of two-compared with one-step testing with different tests; and improved classification of people at high and low risk for LTBI
