Digital cataract photography.

This study compares the cost effectiveness of two methods of grading cataract changes in the Australian population. The conventional film-based method has comparatively low set-up costs, but is more subjective in its assessment and more reliant on manpower, while the digital method has high set-up costs, but the results are more objective and available more quickly using fewer people. By a careful assessment of all the costs involved it is possible to estimate how many participants need to be recruited to a study in order to make the digital method cost effective.

A review of research relevant to custody and access disputes.

With the high rate of marriage breakdown, increasing numbers of children are becoming the subjects of custody and access disputes. The Courts are looking to the services of psychiatrists in these matters. They value our expert opinion on the least detrimental available alternative for the child. This paper reviews available research data which are relevant to psychiatric testimony on the determination of exclusive custody, joint custody and access. It is concluded that there is emerging an objective body of data which can buttress psychiatric opinion in these matters, but that a number of the principles which have guided the Courts to date, have not been thoroughly researched.

Cost-effectiveness of digital cataract assessment.

PURPOSE: The aim of this study was to compare costs of digital photograph grading with that of film-based, human grading of the lens in epidemiological studies involving cataract assessment. METHODS: Cost-effectiveness was measured by establishing the number of participants with ungradeable images and incorporating these lost data into the overall cost per participant for each study. RESULTS: The digital grading system cost was A$105000 with operating costs of $2.81 per participant, with 99.4% effectiveness. The film-based, human grading set-up costs were $43000 with operating costs of $18.49 per participant and 90% effectiveness. After examining 3500 people the use of the digital equipment becomes cost-beneficial. CONCLUSIONS: The high costs of setting up a digital cataract grading system are offset by the low running costs, less ungradeable images and greater accuracy over the duration of a large scale ophthalmic epidemiological study.
