The hospitalisation of death: should more people die at home?

With the increase in the proportion of hospital deaths there is increasing debate about appropriateness of place of death. Death should be a family affair but is increasingly hidden from public view. In contrast to those who die at home, most of those who die in hospital die alone with no relatives or friends with them. Husbands and wives are less likely to have the opportunity to say 'goodbye' to their dying spouses. As people become less familiar with death they may increasingly assume that the terminally ill are better cared for in hospital. However, this need not be the case. Most people want to die at home, most do not for social rather than medical reasons. It is not the illness itself which leads to hospital admission in many cases but its duration and nature--and the type of burden it places on relatives. Although home care should be encouraged where possible, no amount of exhortation to the family or to the dying person of the advantages of home care can disguise the fact that demand for domiciliary services is greater than is now being provided. The paper is based on one read to a London Medical Group Symposium.

Contrast sensitivity functions and specific reading disability.

Contrast sensitivity functions for normal and specifically disabled readers were measured in two experiments. Each study showed that specifically disabled readers and controls differ in the pattern of relative sensitivity across spatial frequencies. Both studies provide evidence of differences between normal and disabled readers on measures of visual mechanisms fundamental to the reading process.

Delegation to nurses in general practice.

A random sample of general practitioners and their nursing staff was interviewed to examine the extent to which the doctors delegated medical tasks to the nurses and to analyse attitudes towards delegation. A significant minority of both doctors and nurses were reluctant to have minor clinical tasks delegated and a majority did not think that nurses should carry out delegated diagnostic procedures. Doctors and nurses who had completed their training since 1960 were more likely to favour delegation than those who had completed their training before 1960. This suggests that delegation may become more common. However, the finding that there is considerable opposition to delegation and that this opposition is often based on feelings of professional threat suggests that many doctors may not be ready to experiment with ways of expanding the nurse's role in general practice.

Specific reading disability: differences in contrast sensitivity as a function of spatial frequency.

Contrast thresholds for sine-wave gratings of spatial frequencies of 2, 4, 12, and 16 cycles per degree were determined for normal and disabled readers at a range of stimulus durations. Normal readers demonstrated monotonically decreasing sensitivity with increasing spatial frequency at exposure durations between 40 and 100 milliseconds. At exposure durations of 150 to 1000 milliseconds, they showed peak sensitivity at 4 cycles per degree. In comparison, disabled readers showed monotonically decreasing sensitivity with increasing spatial frequency at all stimulus durations. The difference in sensitivity pattern across spatial frequencies was greatest at stimulus durations approximately equal to fixation durations during reading.

The effect of spatial frequency and contrast on visual persistence.

The visual persistence of sinusoidal gratings of varying spatial frequency and contrast was measured. It was found that the persistence of low-contrast gratings was longer than that of high-contrast stimuli for all spatial frequencies investigated. At higher contrast levels of 1 and 4 cycles deg-1 gratings, a tendency for persistence to be independent of contrast was observed. For 12 cycles deg-1 gratings, however, persistence continued to decrease with increasing contrast. These results are compared with recently published data on other temporal responses, and are discussed in terms of the different properties of sustained and transient channels.
