According to reports, shortly before Jemima died, the subject of organ donation had come up in discussions with her family, prompted by the death of a family friend in a car accident. Decisions about organ donation are extremely difficult.
Download powerpoint Impact of presumed consent on organ donation rates in before and after studies Before and after studies have the benefit of exploring the experience of individual countries but, because it is an uncontrolled study design, it is not possible to rule out the influence of other known or unknown factors influencing donation rates.
In Austria the 4. View inline However, there was limited exploration of other changes such as increased publicity and organisational and infrastructure changes that might have taken place at the same time as the change in legislation. As such factors are likely to influence donation rates, it is unclear to what extent the increases found were directly attributable to the change in legislation.
Therefore, any relation found between presumed consent and organ donation rate is associative and cannot show whether the effect was directly attributable to the intervention, and this is reflected in the quality assessment.
Table 2 Details of between country comparison studies of legislation for presumed consent for organ donation View this table: View inline Six studies included factors likely to influence organ donation rates, such as mortality from road traffic crashes and health systems, in their analyses.
The number of countries and their rationale for inclusion varied, but several countries were common across more than one study. Therefore, in this study 10 countries were classified as having explicit consent de facto, and in the other studies they were classified as having presumed consent legislation.
Switzerland has a national informed consent law, but many of its constituent jurisdictions cantons have their own presumed consent laws: View inline The studies also varied in the sources of data used, the time period covered, and the type of analyses performed.
Three of the four studies showed a significant association between presumed consent and increased organ donation rates.
Jan 15, · Abstract. Objectives To examine the impact of a system of presumed consent for organ donation on donation rates and to review data on attitudes towards presumed consent.. Design Systematic review.. Data sources Studies retrieved by online searches to January of Medline, Medline In-Process, Embase, CINAHL, . Within the European Union, organ donation is regulated by member kaja-net.com of , 24 European countries have some form of presumed consent (opt-out) system, with the most prominent and limited opt-out systems in Spain, Austria, and Belgium yielding high donor rates. Spain had the highest donor rate in the world, per million people in the . Still, efforts at organ donation consent policy reform in the US have been fruitless. Colorado, Texas and Pennsylvania legislators, for example, have pushed for presumed consent. Colorado, Texas and Pennsylvania legislators, for example, have pushed for presumed consent.
Further details about these are available in the full report. In the one study that considered it, transplant capacity defined as the number of transplant centres per million population was positively associated with higher donation rates and within the statistical model it was the factor with the greatest predictive strength, greater than presumed consent practice, religion, and education.
The percentage of the population in higher education was included in one study, in order to assess the influence of social demographics on donation rates, and there was a significant positive association.
For example, only one study included Latin American and South American countries. Blood donation rate was investigated as an indicator of social preferences towards organ donation in one study, and it showed a positive though non-significant association with organ donation rates.
Attitudes to presumed consent As the UK surveys are of most relevance, only these are reported here. Table 4 UK population surveys of attitudes to organ donation and presumed consent View this table: View inline The surveys took place between the mids and Details of the survey methods in the full reports were fairly limited.
Details of sampling methods were not available for four surveys,ww26 and they varied in how they framed the questions on presumed consent. Discussion Principal findings We conducted a systematic review investigating the impact of presumed consent legislation on organ donation rates; to our knowledge this is the first review to address this question.
We found four good quality studies comparing organ donation rates between countries with and without systems of presumed consent. All four found an association between presumed consent legislation and higher organ donation rates, and in three this was statistically significant. Estimates of the size of the effect varied: In at least one study, mortality from road traffic accidents, the number of transplant centres, gross domestic product per capita, and health expenditure per capita were found to be important.
Five before and after studies also showed an increase in organ donation rates following the introduction of presumed consent.Wales' "presumed consent" organ donation system assumes people want to donate their organs unless they specifically say otherwise – a departure from the opt-in policy employed throughout the U.S.
In recent years, technical, political and public opinion in many countries has shifted towards the view that opt-out provisions can help promote organ donation. Two components of transplantation legislation – presumed consent and allocation priority – are thought to increase the donor population.

If you have already signed up to be an organ donor, you are able to change. Presumed Consent is an Attractive Concept with Unattractive Results.
The waiting list for organ transplants has exceeded , [i] and is growing roughly 10% a year, despite more than 28, [ii] transplants being performed annually, and with the diseases of aging and obesity that damage organs, this trend is expected to worsen. [iii] While prevention .
Organ transplantation can be the best treatment for some illnesses. But treatment depends on the availability of donated organs, and supply is a perennial problem.
There are long waiting lists and.
