Measuring clinical outcome

At the present time, there are many fundamental issues coming from the Department of Health or from other national organizations, which will have an effect on the future development of the dietetic profession. The British Diatetic Association (BDA) Professional Development Committee will consider these issues, as and when appropriate, and will publish the information in the form of Briefing Papers.
The first Briefing Paper on 'Quality Assurance' was published by the BDA in November 1989. The second on 'Measuring clinical outcome' is published below. In each case the opinion of BDA members and specialist groups has been sought and the Professional Development Committee wishes to thank individuals and the specialist groups for their comments.
The Briefing Papers are intended to provide information and promote discussion among the membership. I would welcome further comments from readers, which may be directed to the British Dietetic Association Office.     

Mandibular displacement in Angle Class II, Division 2 malocclusion

The effect of the treatment of Angle Class II, Division 2 malocclusion was studied in 22 children by x-ray cephalometry and by recording the relation between the retruded and the intercuspal mandibular positions. The treatment was performed in three phases. In the first phase the upper incisors were proclined, and the deep bite was corrected with an upper removable plate. In the second phase the distal occlusion was corrected with an activator. The result was retained in the third phase with a second activator designed for retention. The relation between the retruded (RCP) and the intercuspal (ICP) mandibular positions was recorded with wax bites and dental casts mounted in a modified gnathothesiometer. The anteroposterior distance between RCP and ICP was large before the start of the treatment. The distance was unchanged after proclination of the upper incisors and correction of the deep bite but decreased after correction of the distal occlusion and increased again somewhat during the retention phase. The proclination of the upper incisors and the correction of the deep bite (phase one of the treatment) did not result in mandibular anterior positioning. This fact and the results of the recordings of the relation between RCP and ICP were interpreted as evidence that the mandible is not posteriorly displaced in Class II, Division 2 malocclusion.     

The future of healthcare and the pharmaceutical industry – a CEO view

In the century or so since the birth of the research-based pharmaceutical industry, there has never been a more demanding time. The most pressing issue facing virtually all big pharmaceutical companies today is research and development productivity. Despite huge investments in research and development, the number of new medicines cleared for market has declined. On the other hand, there has never been a more exciting time to do healthcare research. New sciences and technologies are opening up radically new perspectives and opportunities for the future. Medical practice is undergoing a historic shift towards more personalized medicine. Over the next 10 years we can expect significant progress in the treatment of major diseases.
