Kihlbom has recently argued that a system of seeking negatively informed consent might be preferable in some cases to the ubiquitous informed consent model. Although this theory is perhaps not powerful enough to supplant informed consent in most settings, it lends strength to Evans’ and Hungin’s proposal that it can be ethical to prescribe placebos rather than "active" drugs. This paper presents an argument for using negatively informed consent for the specific purpose of authorising the use of placebos in clinical contexts.

In the last year there has been a great deal of public debate about homeopathy. The House of Commons Select Committee on Science and Technology concluded in November that there is no evidence base for homeopathy, and agreed with some academic commentators that homeopathy should not be funded by the NHS.i ii While homeopathic doctors and hospitals are quite commonplace, some might be surprised to learn that there are also many homeopathic dentists practicing in the UK. This paper examines some of the claims made by homeopathic organisations regarding dentistry, and suggests that they may not be entirely ethical.

The annual UK potential donor audit captures families’ reasons for not consenting to donation of their deceased family members’ organs . Given that many families’ refusals and vetoes are based on false beliefs, cognitive bias and misunderstanding, it is incumbent upon doctors, nurses and transplant coordinators to invest sufficient time to facilitate informed consent or authorization. While such families are distressed, organ donation rates could be substantially improved if they were made aware of any mistaken beliefs, using recently suggested criteria for the ethical use of persuasion . This article examines some of the reasons for refusal of donation and suggests ways to help families make better decisions. It emerges that the use of persuasion is ethically essential in order to prevent families making decisions that they may come to regret.

Despite the heavy emphasis on consent in the ethical code of the General Dental Council (GDC), it is often overlooked that communication difficulties between patient and dentist can cause problems in maintaining genuine consent during interventions. Inconsistencies in the GDC's Standards for dental professionals and Principles of patient consent guidelines are examined in this article, and it is concluded that more emphasis must be placed on continuous consent as an ongoing process essential to maintaining patients' dignity in dentistry.

Homeopathic medicine is based on the two principles that “like cures like” and that the potency of substances increases in proportion to their dilution. In November 2009 the UK Parliament’s Science and Technology Committee heard evidence on homeopathy, with several witnesses arguing that homeopathic practice is “unethical, unreliable, and pointless”. Although this increasing scepticism about the merits of homeopathy is to be welcomed, the unethical effects of funding homeopathy on the NHS are even further-reaching than has been acknowledged.
