Planning for chemical incidents by implementing a Delphi based consensus study.
(41/739)
This paper provides a practical approach to the difficulties surrounding planning for chemical incidents, based upon the results of a Delphi based consensus study. It is intended to offer advice, which can be implemented at regional and local prehospital and hospital level. The phases of the response that are covered include preparation, management of the incident, delivery of medical support during the incident, and recovery and support after the incident. (+info)
Using a mock trial to make a difficult clinical decision.
(42/739)
Many clinical decisions have to be taken with inadequate scientific information. Reaching a consensus among experts has been tried as one response to this problem. Another, described here, is to use legal process to dissect a difficult question. In this case a mock trial--using barristers, expert witnesses, and a jury--was conducted on whether bone marrow transplantation should be offered to all children with symptomatic sickle cell disease. Transplantation seems to offer about a 90% cure rate for a condition that may kill 15% of children before they reach 20. But transplantation carries a 10% risk of death or severe disability, and doctors cannot predict which children will suffer severely from their sickle cell disease and which will suffer little or nothing. The jury eventually reached a majority decision that transplantation should not be offered now to all symptomatic children. (+info)
Achieving national health objectives: the impact on life expectancy and on healthy life expectancy.
(43/739)
Our study quantifies the impact of achieving specific Healthy People 2010 targets and of eliminating racial/ethnic health disparities on summary measures of health. We used life table methods to calculate gains in life expectancy and healthy life expectancy that would result from achievement of Healthy People 2010 objectives or of current mortality rates in the Asian/Pacific Islander (API) population. Attainment of Healthy People 2010 mortality targets would increase life expectancy by 2.8 years, and reduction of population wide mortality rates to current API rates would add 4.1 years. Healthy life expectancy would increase by 5.8 years if Healthy People 2010 mortality and assumed morbidity targets were attained and by 8.1 years if API mortality and activity limitation rates were attained. Achievement of specific Healthy People 2010 targets would produce significant increases in longevity and health, and elimination of racial/ethnic health disparities could result in even larger gains.

The standard of care debate: the Declaration of Helsinki versus the international consensus opinion.
(44/739)
The World Medical Association's revised Declaration of Helsinki endorses the view that all trial participants in every country are entitled to the worldwide best standard of care. In this paper the authors show that this requirement has been rejected by every national and international committee that has examined this issue. They argue that the consensus view now holds that it is ethically permissible, in some circumstances, to provide research participants less than the worldwide best care. Finally, the authors show that there is also consensus regarding the broad conditions under which this is acceptable. (+info)
The standard of care debate: against the myth of an "international consensus opinion".
(45/739)
It is argued by Lie et al in the current issue of the Journal of Medical Ethics that an international consensus opinion has formed on the issue of standards of care in clinical trials undertaken in developing countries. This opinion, so they argue, rejects the Declaration of Helsinki's traditional view on this matter. They propose furthermore that the Declaration of Helsinki has lost its moral authority in the controversy in research ethics. Although the latter conclusion is supported by this author, it will be demonstrated in this paper that there is not such a thing as an international consensus opinion, and that the authorities used by Lie et al as evidence in support of their claim should not be relied upon as authorities or final arbiters in this debate. Furthermore, it will be shown that arguments advanced substantively to show that lower standards of care are ethically acceptable in the developing world, conflate scientific with economic reasons, and ultimately fail to bolster the case they are designed to support.

Cultural consensus analysis as a tool for clinic improvements.
(46/739)
Some problems in clinic function recur because of unexpected value differences between patients, faculty, and residents. Cultural consensus analysis (CCA) is a method used by anthropologists to identify groups with shared values. After conducting an ethnographic study and using focus groups, we developed and validated a CCA tool for use in clinics. Using this instrument, we identified distinct groups with 6 important value differences between those groups. An analysis of these value differences suggested specific and pragmatic interventions to improve clinic functioning. The instrument has also performed well in preliminary tests at another clinic.

Development of clinical practice guidelines: evaluation of 2 methods.
(47/739)
The aim of this study was to compare 2 methods for developing a clinical practice guideline (CPG) on the management of asymptomatic, impacted mandibular third molars. Outcome measures were the mean time invested by the participants for each method, the quality of the CPGs measured using the Appraisal of Guidelines for Research and Evaluation (AGREE) indicator and observations of the group discussions. We used a national consensus procedure following the Rand modified Delphi procedure (2 panels) and a local consensus procedure (2 existing dental peer groups). The mean time spent was about equal for the 2 methods. The quality of the CPGs developed by the expert panels was higher than that of the CPGs developed by the dental peer groups. Observation indicated that all group processes were influenced by the chairperson. We concluded that the expert panel method is suitable for developing reliable CPGs on a national or regional level.

The problem of appraising qualitative research.
(48/739)
Qualitative research can make a valuable contribution to the study of quality and safety in health care. Sound ways of appraising qualitative research are needed, but currently there are many different proposals with few signs of an emerging consensus. One problem has been the tendency to treat qualitative research as a unified field. We distinguish universal features of quality from those specific to methodology and offer a set of minimally prescriptive prompts to assist with the assessment of generic features of qualitative research. In using these, account will need to be taken of the particular method of data collection and methodological approach being used. There may be a need for appraisal criteria suited to the different methods of qualitative data collection and to different methodological approaches. These more specific criteria would help to distinguish fatal flaws from more minor errors in the design, conduct, and reporting of qualitative research. There will be difficulties in doing this because some aspects of qualitative research, particularly those relating to quality of insight and interpretation, will remain difficult to appraise and will rely largely on subjective judgement.
