Geochemistry and health in the United Kingdom.

Before the 1960s, comparisons between the distribution of trace elements in the environment and health in the United Kingdom were primarily confined to ad hoc studies in areas associated with particular agricultural disorders or with unusual human mortality or morbidity records. More recently, increasing interest in the importance of trace elements in crop and animal production and in the hazards of environmental pollution have created a need for more systematic geochemical data. Geochemical reconnaissance maps for England, Wales, Northern Ireland and parts of Scotland have demonstrated the extent of many known clinical trace element problems in agriculture and have also been valuable in delineating areas within which subclinical disorders may occur. Their application to studies on the composition of soils, food crops and surface waters in relation to public health has proved encouraging. Current knowledge and present investigations into environmental geochemistry and human health in the U.K. are reviewed, together with future research requirements.     

Retirement on grounds of ill health: cross sectional survey in six organisations in United Kingdom.

OBJECTIVE: To assess the process and outcome of retirement due to ill health in six large organisations. DESIGN: Cross sectional study of the rate of retirement due to ill health by age, sex, and length of service. Principal diagnoses by age and length of service were also compared. SETTING: Four public and two private large employers in the United Kingdom. MAIN OUTCOME MEASURES: Rates of retirement on the grounds of ill health by age, sex, and length of service of employees contributing to pension schemes. RESULTS: Rates of ill health retirement varied from 20 to 250 per 10,000 contributing members, and in two organisations the rate varied geographically within the same organisation. In the two organisations that provided data by sex, women retired at a greater rate than men under age 40 and over age 50. In four organisations the modal age or length of service coincided with enhancements in benefits. In the four that provided information on diagnoses, musculoskeletal and minor psychiatric illnesses were the most common reasons for retirement. CONCLUSION: The granting of ill health retirement benefits may not be determined by illness. There is a need for some employers and pension schemes to improve their processes for granting benefits. Doctors should be wary of conflicts of interest and work to guidelines when they advise pension schemes about the merits of an application for benefits.     

Collection and validation of data in the United Kingdom Atomic Energy Authority mortality study.

The United Kingdom Atomic Energy Authority mortality study investigated the relation between mortality and recorded exposure to ionising radiation among employees working at the authority''s seven establishments between 1946 and 1979. This report examines the design of the study and methods of data collection and validation. The completeness of the study population was deemed to be unsatisfactory at two establishments, where records of employment before 1965 had been destroyed. Assessment of the magnitude of the deficit led to the conclusion that the data from these establishments were too incomplete for inclusion in the mortality analysis. At the other establishments validation showed that the data collected were accurate and unbiased. Certain characteristics of the 39 546 employees included in the mortality analysis were identified which were relevant in interpreting the findings.     

Public preferences for health care: prioritisation in the United Kingdom

The Government in the UK is encouraging consumerism within health care and is requiring Health Authorities to consult with the public on prioritisation of resources. Public consultation within the National Health Service (NHS) has had limited success in the past. Many of the techniques used are flawed. Despite the limited scope of the public surveys conducted so far, a number of themes have emerged: a willingness to pay for experimental, 'high-tech' life-saving treatments rather than more cost-effective treatments which will improve quality of life, which are more likely to maximise utility from the scarce resources available; preference for treating the young rather than the old; preference for treating patients with dependents (e.g. spouse, children) rather than those who have none; a willingness to discriminate against those patients who were partially responsible for their illness due to choice of 'unhealthy' lifestyle (e.g. smoking cigarettes, drinking excess alcohol). These public preferences raise ethical problems. For example, is it just to spend more on heroic treatments which are likely to fail? Is there a right to health care irrespective of whether you have had 'a fair innings' or whether a patient is in part responsible for their illness due to an unhealthy lifestyle? If there are ethical concerns about these preferences, should health authorities consult with the public at all? Is human life and suffering incommensurable, and hence is it impossible to prioritise anyway? Some of the ethical consequences of using empirical data on public preferences are discussed.     

Incidence of AIDS and excess of mortality associated with HIV in haemophiliacs in the United Kingdom: report on behalf of the directors of haemophilia centres in the United Kingdom.

OBJECTIVE--To estimate the cumulative incidence of AIDS by time since seroconversion in haemophiliacs positive for HIV and to examine the evidence for excess mortality associated with HIV in those who had not yet been diagnosed as having AIDS. DESIGN--Analysis of data from ongoing national surveys. SETTING--Haemophilia centres in the United Kingdom. PATIENTS--A total of 1201 men with haemophilia who had lived in the United Kingdom during 1980-7 and were positive for HIV. INTERVENTION--None. END POINTS--Diagnosis of AIDS; death in those not diagnosed as having AIDS. MEASUREMENTS AND MAIN RESULTS--Estimation of cumulative incidence of AIDS and number of excess deaths in seropositive patients not diagnosed with AIDS. Median follow up after seroconversion was 5 years 2 months. Eight five patients developed AIDS. Cumulative incidence of AIDS five years after seroconversion was 4% among patients aged less than 25 at first test positive for HIV, 6% among those aged 25-44, and 19% among those aged greater than or equal to 45. There was little evidence that type or severity of haemophilia or type of factor VIII or IX that had caused HIV infection affected the rate of progression to AIDS. Mortality was increased among those who had not been diagnosed as having AIDS, especially among those with "AIDS related complex." Thirteen deaths were observed among 36 patients diagnosed as having AIDS related complex against 0.65 expected, and 34 deaths in 1080 other patients against 22.77 expected; both calculations were based on mortality rates observed in haemophiliacs in the United Kingdom in the late 1970s. CONCLUSIONS--Rate of progression to AIDS depended strongly on age. There is a substantial burden of fatal disease among patients positive for HIV who have not been formally diagnosed as having AIDS.     

Provision of facilities for secondary transport of seriously ill patients in the United Kingdom

A survey by questionnaire of 280 hospitals with general intensive care units was carried out to find out what facilities were provided for secondary transport of seriously ill patients in the United Kingdom. Replies were received from 181 units. Extrapolating from the survey data showed that about 10 000 patients were transported each year, although many units transferred only a few patients. An appreciable minority of units reported that facilities for secondary transport were inadequate and many were obliged to send inexperienced medical staff with patients. Almost half of the respondents thought that arrangements for transfer were unsatisfactory, but only a tenth said that they delayed or refused transfer for this reason. This undoubtedly reflects a policy of “making do” despite inadequate resources.We believe that these results support the concept of regional transport services, where each major unit would be adequately equipped and staffed and unnecessary duplication of resources avoided.     

Surveillance of AIDS in the United Kingdom.

The surveillance of cases of the acquired immune deficiency syndrome (AIDS) in the United Kingdom is described and a preliminary analysis made of the 1012 cases that were reported to the end of August 1987. Homosexuals were the largest risk group. For the first time it is possible to present cases by the date of diagnosis and by the regional health authority of residence. The rate of increase of new cases shows no sign of slowing down. One third of patients with AIDS lived in a different regional health authority from that in which their disease had been diagnosed. The geographical distribution varied with the risk group. The commonest presenting clinical feature at diagnosis was Pneumocystis carinii pneumonia. Kaposi''s sarcoma was considerably more common among homosexuals than among people in other groups at risk.     

Climate change and local public health in the United States: preparedness, programs and perceptions of local public health department directors

While climate change is inherently a global problem, its public health impacts will be experienced most acutely at the local and regional level, with some jurisdictions likely to be more burdened than others. The public health infrastructure in the U.S. is organized largely as an interlocking set of public agencies at the federal, state and local level, with lead responsibility for each city or county often residing at the local level. To understand how directors of local public health departments view and are responding to climate change as a public health issue, we conducted a telephone survey with 133 randomly selected local health department directors, representing a 61% response rate. A majority of respondents perceived climate change to be a problem in their jurisdiction, a problem they viewed as likely to become more common or severe over the next 20 years. Only a small minority of respondents, however, had yet made climate change adaptation or prevention a top priority for their health department. This discrepancy between problem recognition and programmatic responses may be due, in part, to several factors: most respondents felt personnel in their health department--and other key stakeholders in their community--had a lack of knowledge about climate change; relatively few respondents felt their own health department, their state health department, or the Centers for Disease Control and Prevention had the necessary expertise to help them create an effective mitigation or adaptation plan for their jurisdiction; and most respondents felt that their health department needed additional funding, staff and staff training to respond effectively to climate change. These data make clear that climate change adaptation and prevention are not currently major activities at most health departments, and that most, if not all, local health departments will require assistance in making this transition. We conclude by making the case that, through their words and actions, local health departments and their staff can and should play a role in alerting members of their community about the prospect of public health impacts from climate change in their jurisdiction.
