The incremental value of internet-based instruction as an adjunct to classroom instruction: a prospective randomized study.

PURPOSE: Computer-based methods of instruction offer the possibility of helping medical students to learn clinical skills and professionalism. Without rigorous documentation of its pedagogic advantages, the utility of Internet-based teaching is not solidly grounded. The authors carried out a prospective, randomized study of educational outcomes, comparing a traditional classroom course in clinical ethics with the same course supplemented by Internet-based discussion. METHODS: Introduction to Clinical Ethics is a sophomore medical school course that teaches a specific method for analyzing clinical ethical problems. One sophomore class was randomly assigned to either classroom teaching alone (traditional group; n = 65) or classroom teaching supplemented with Internet-based discussions of cases illustrating ethical issues (Internet component group; n = 62). A final case analysis comprehensively evaluated students' understanding of the analytic method taught in the course. Grades for both groups on the final case analyses, which were rated by two external reviewers, were compared. RESULTS: The students' understanding of ethical analysis, as measured by grades of external reviewers on the final paper, was significantly higher for those in the course with the Internet component than it was for those in the traditional course (3.0 +/- 0.6 and 2.6 +/- 0.7, respectively; p <.005). CONCLUSION: The study documents the incremental value of Internet-based teaching of clinical ethics to sophomore medical students.

Taking the "I" out of IRB--and putting "community" in.

If one looks back on the history of American research ethics, a bold pattern emerges. Since World War II, about every twenty years or so a breach of the social contract between investigators and human research subjects galvanizes public and professional interest in the ethical foundations and oversight mechanisms governing research with humans.

Commentary: mal-intentioned illiteracy, willful ignorance, and fetal protection laws: is there a lexicologist in the house?

Author argues that fetal protection laws result from the antiabortion agenda, not from concern for child health. Such laws derive from rhetorical dissembling, not careful crafting of public health policy.

Ethical issues in umbilical cord blood banking. Working Group on Ethical Issues in Umbilical Cord Blood Banking.

OBJECTIVE: Banking umbilical cord blood (UCB) to be used as a source of stem cells for transplantation is associated with a set of ethical issues. An examination of these issues is needed to inform public policy and to raise the awareness of prospective parents, clinicians, and investigators. PARTICIPANTS: Individuals with expertise in anthropology, blood banking, bone marrow transplantation, ethics, law, obstetrics, pediatrics, and the social sciences were invited to join the Working Group on Ethical Issues in Umbilical Cord Blood Banking. EVIDENCE: Members were assigned topics to present to the Working Group. Following independent reviews, background materials were sent to the Working Group. CONSENSUS PROCESS: Individual presentations of topics at a 2-day meeting were followed by extensive group discussions in which consensus emerged. A writing committee then drafted a document that was circulated to the entire Working Group. After 3 rounds of comments over several months, all but 1 member of the Working Group agreed with the presentation of our conclusions. CONCLUSIONS: (1) Umbilical cord blood technology is promising although it has several investigational aspects; (2) during this investigational phase, secure linkage should be maintained of stored UCB to the identity of the donor; (3) UCB banking for autologous use is associated with even greater uncertainty than banking for allogeneic use; (4) marketing practices for UCB banking in the private sector need close attention; (5) more data are needed to ensure that recruitment for banking and use of UCB are equitable; and (6) the process of obtaining informed consent for collection of UCB should begin before labor and delivery.

Influence of political power, medical provincialism, and economic incentives on the rationing of surgical intensive care unit beds.

OBJECTIVE: To determine factors influencing rationing decisions in a surgical ICU during a temporary nursing shortage when two to six of the unit's 16 beds were closed. DESIGN: Blinded, concurrent data collection, retrospective chart review. SETTING: Surgical ICU. PATIENTS: All patients (n = 308) for whom a surgical ICU bed was requested were studied during a 3-month period. MEASUREMENTS AND MAIN RESULTS: Admitting patterns did not change and no attempts were made to limit admissions to more severely ill patients during times of the greatest shortage of surgical ICU beds. Contrary to findings in previous reports, the severity of illness of patients admitted to the surgical ICU decreased as bed availability and bed census decreased. Bed allocation across surgical services was influenced by factors other than medical suitability. Of major users, cardiothoracic surgery experienced the highest percentage (59%) of all patient admissions and lowest percentage (1.6%) of all denied admissions. General surgery experienced the lowest percentage (15%) of all admissions and highest percentage (10.4%) of all denied admissions, although these patients had the highest average Acute Physiology and Chronic Health Evaluation (APACHE II) scores for all patients admitted (17.7) and for patients denied admission (15.8). CONCLUSIONS: Surgical attending physicians rarely used other open inhouse ICU beds when surgical ICU beds were unavailable. Political power, medical provincialism, and income maximization overrode medical suitability in the provision of critical care services.
