The Human genome project and genetic research: what are the implications for ethics and equity?

The Human Genome Project and related genetic research are exciting scientific quests that are also giving rise to significant ethical dilemmas and equity considerations. These include: the question of where to draw the line, e.g. is research on human cloning ethical, privacy of genetic and medical records, genetic discrimination, implications for public health programmes, unequal access to new but expensive therapeutic interventions, ‘playing God’, and patenting and commercialization of genetic material (including those obtained surreptitiously from Third World countries by individuals and multinational corporations from developed countries). The Human Genome Project is an example of technological progress threatening to outpace the adjustment ability of existing socioeconomic institutions. It has also given rise to the need to rethink the relationship between advances in the biomedical sciences and equity issues.     

Integrity and moral residue: nurses as participants in a moral community

Abstract This paper will examine the concepts of integrity and moral residue as they relate to nursing practice in the current health care environment. I will begin with my definition and conception of ethical practice, and, based on that, will go on to argue for the importance of recognizing that nurses often find themselves in the position of compromising their moral integrity in order to maintain their self‐survival in the hospital or health care environment. I will argue that moral integrity is necessary to a moral life, and is relational in nature. When integrity is threatened, the result is moral distress, moral residue, and in some cases, abandonment of the profession. The solution will require more than teaching bioethics to nursing students and nurses. It will require changes in the health care environment, organizational culture and the education of nurses, with an emphasis on building a moral community as an environment in which to practise ethically.     

Perspectives on colorectal cancer screening: a focus group study

Objective To assess attitudes and acceptability of Ontario consumers and doctors towards colorectal screening with faecal occult blood testing (FOBT) and colonoscopy. Design, setting and participants Focus groups with gender‐specific samples of the population, high‐risk gastroenterology patients and family doctors. Method Semi‐structured interview guides used by facilitator to lead groups through knowledge of risk factors and prevention of colorectal cancer, the screening modalities, requirements for implementing screening programmes, barriers to screening and preferences towards screening. Main findings There were low levels of knowledge about colorectal cancer and its prevention in the general population. FOBT was an acceptable screening modality, but considerable education about its use and benefits would be necessary to implement a screening programme. Colonoscopy was not perceived to be a good choice for a primary screen in the general population. The high‐risk group supported use of FOBT in the general population and emphasized the need for education. The doctors were more reluctant about screening, requesting clear guidelines. They also identified the time and resources that would be required if a screening programme were initiated. Conclusion While colorectal screening is acceptable in this sample, information and decision aids are required to enable consumers and providers to make effective decisions. Implementation of colorectal screening programmes requires substantial educational efforts for both consumers and doctors.     

Pilot study of abuse of asthma inhalers by middle and high school students

During a school-based survey, middle and high school students (n = 1536) reported on their nonprescribed, lifetime use of asthma inhalers. Approximately 15% of 8th and 9th graders reported using nonprescribed asthma inhalers; the odds for this behavior were significantly higher for these students (2.25 and 2.30, respectively) and the nonprescribed use of asthma inhalers was significantly associated with higher rates of other drug use.     

Methodology in meta–analysis: a study from Critical Care meta–analytic practice

Methodological aspects of meta-analytic practice, heterogeneity, publication bias, metaregression and effect metric, were investigated in 14 meta-analyses reflecting major therapeutic concern in Critical Care practice. Compared with the standard Q test, the exact Zelen test was more sensitive in identifying heterogeneity. Assessment of heterogeneity impact by the I ² statistic was consistent with inferences afforded by both the Q and Zelen test. Publication bias was subject to test and metric determination: funnel plots exhibited variable asymmetry across studies and between metrics; the regression asymmetry test appeared more sensitive than the rank correlation test; the “trim and fill” method was the most sensitive, but suggested, on the basis of quantification of the effects of potentially missing studies, that meta-analyses may be resistant to such missingness. Metaregression of treatment effect against control risk using Bayesian hierarchical regression in all metrics (log odds ratio, log risk ratio and RD) suggested that naïve linear regression approaches over-diagnosed significant relationships and exhibited regression dilution. Heterogeneity, publication bias and risk related treatment effects all demonstrate estimator and metric dependence; the RD metric would appear the most capricious in this regard.     

Quality of Care for Acute Myocardial Infarction in Rural and Urban US Hospitals

CONTEXT: Acute myocardial infarction (AMI) is a common and important cause of admission to US rural hospitals, as transport of patients with AMI to urban settings can result in unacceptable delays in care. PURPOSE: To examine the quality of care for patients with AMI in rural hospitals with differing degrees of remoteness from urban centers. METHODS: This cohort study used data from the Cooperative Cardiovascular Project (CCP), including 4,085 acute care hospitals (408 remote small rural, 893 small rural, 619 large rural, and 2,165 urban) with 135,759 direct admissions of Medicare beneficiaries ages 65 and older for a confirmed AMI between February 1994 and July 1995. Outcomes included use of aspirin, reperfusion, heparin, and intravenous nitroglycerin during hospitalization; use of beta-blockers, aspirin, and angiotensin-converting enzyme (ACE) inhibitors at discharge; avoidance of calcium channel blockers at discharge; and 30-day mortality. FINDINGS: Substantial proportions of Medicare beneficiaries in both urban and rural hospitals did not receive the recommended treatments for AMI. Medicare patients in rural hospitals were less likely than urban hospitals' patients to receive aspirin, intravenous nitroglycerin, heparin, and either thrombolytics or percutaneous transluminal coronary angioplasty. Only ACE inhibitors at discharge was used more for patients in rural hospitals than urban hospitals. Medicare patients in rural hospitals had higher adjusted 30-day post-AMI death rates from all causes than those in urban hospitals (odds ratio for large rural 1.14 [1.10 to 1.18], small rural 1.24 [1.20 to 1.29], remote small rural 1.32 [1.23 to 1.41]). CONCLUSIONS: Efforts are needed to help hospital medical staffs in both rural and urban areas develop systems to ensure that patients receive recommended treatments for AMI.
