Skin cancer attitudes: a cross-national comparison.

A questionnaire concerning attitudes towards skin cancer, sun exposure and general environmental issues was administered to 132 holiday-makers on a beach in south-west England and (in translation) to 142 visitors to another beach in north-west Italy. Following the Janis & Mann (1977) classification of strategies for coping with decision conflicts, subscales were derived measuring tendencies to 'avoid' thinking about environmental issues, to 'bolster' prior attitudes (by playing down the seriousness of the risk of skin cancer while attending to the pleasures of sunbathing), and to be 'vigilant' concerning risk information and the need for specific protective behaviour (e.g. sunscreen use). The British scored higher than the Italians, and women higher than men, on vigilance, but there were no gender or nationality differences on the other subscales considered as a whole. Responses were also related to the covariates of age and self-reported vulnerability to sunburn. Those who showed less concern with environmental issues also tended to play down the risks of skin cancer and be less vigilant with regard to self-protection. It is suggested that health promotion should address both cultural norms concerning exposure to the sun and people's intuitive notions about their relative personal vulnerability.

Communicating the diagnosis of lung cancer.

In order to assess their reaction to the information given, 50 patients underwent a semi-structured interview with a social worker within 1 week of having been told the diagnosis of lung cancer. There were 32 men and 18 women with a mean age of 63 (range 38-82) years. Thirty-eight (76%) belonged to Registrar General social class IV or V, and 45 (90%) had left school at the age of 15 years. Two patients were unaware of the diagnosis despite having been told that they had lung cancer. Two patients would have preferred not to have been told the diagnosis and two were unsure, while 46 (92%) felt that telling them the diagnosis truthfully had been correct. No patient felt that they had been given too much information, but 13 (26%) indicated a lack of information about prognosis. Despite being told 'bad news', 31 (62%) felt more reassured after their interview with the doctor, 5 (10%) felt less reassured, and 14 (28%) were uncertain. Twenty-one (42%) patients were experiencing a sense of guilt or regret at having smoked. Many patients had concerns about specific symptoms which they expected to suffer. In general, patients wanted to be told their diagnosis truthfully and required a high level of information. Many patients felt reassured by the discussion of such details.

The effect of dementia on acute care in a geriatric medical unit.

Treatment of dementia costs billions of dollars in long-term care and community services every year. Dementia also burdens the acute care system and may contribute to financial problems for hospitals serving large numbers of demented elderly. In a specialized geriatric medical unit devoted to acute care of the frail elderly, Alzheimer's disease and vascular and mixed dementias afflicted 63% of inpatients and were associated with excess consumption of nursing resources, complications of treatment, nosocomial infections, lengthy hospitalizations, and financial losses to the hospital. Due in part to the effects of dementia on mobility, continence, and nutrition, demented patients suffered more frequently from life-threatening infections, sepsis, iatrogenic disease, and prolonged hospital stays. Hospital losses were 75% higher for demented patients than for nondemented patients. Dementia affected the majority of acute care patients in this study. However, it was rarely coded as an admitting diagnosis, even though it may have been the proximate cause of the medical morbidity which led to the acute hospitalization. In addition, despite the significant impact of dementia on the hospital course and costs, it was a factor in hospital reimbursement in less than one third of cases. The results indicate that dementia was not considered to be an acute diagnosis, nor was it recognized as a complex medical illness. The impact of dementia on acute hospitalization, including the mechanisms by which dementia prolongs the hospital stay, requires further investigation.

Studies of hospital social stays in the frail elderly and their relationship to the intensity of social work intervention.

The elderly frequently suffer long lengths of hospital stay (LOS). These long stays are often associated with long social care stays which occur when patients no longer require acute care and are awaiting post-discharge services. In this study, actual acute care LOS and social care LOS were studied specifically in hospitalized frail elderly. Our data demonstrate that frail elderly receiving only acute care do not suffer markedly prolonged total LOS (TLOS). However, in hospitalized frail elderly patients who experience acute care and social care stays, social care LOS accounts for over half of all hospital days. When patients were grouped and studied according to the type of post-discharge services being sought by the health care team, significant differences in acute LOS and social care LOS were noted. Subgroups of patients were also identified among the various groups which differed significantly in their LOS parameters. Patients who required more than one discharge plan during the course of hospitalization experienced the longest hospital stays of all groups, and spent almost 70% of these days receiving non-acute social care. In a study of the relationship between the intensity of social work intervention and social care LOS in the frail elderly, a statistically significant relationship was noted between the timing and frequency of social work intervention and the actual length of social care stays. Early and frequent social work interventions were associated with significantly shorter social care LOS. We conclude that the study of TLOS should include acute LOS and social care LOS to obtain a reliable measure of the course and cost of hospital care for the frail elderly. The study of social care subgroups may facilitate future investigations to define the social care problems which contribute most to TLOS, and the patient populations which should be most heavily targeted for early and intensive social work intervention.

MAST-associated compartment syndrome (MACS): a review.

Compartment syndromes occur following lower extremity injuries and have been associated with the use of pneumatic or "medical" antishock trousers (MAST). Review of 12 previously reported cases and 15 new cases suggests that lower extremity trauma and systemic hypotension are cofactors responsible for the development of compartment syndrome but MAST use also contributes to the process by prolonging muscle ischemia. Complications of lower limb compartment hypertension may be averted by early recognition and fasciotomy. Associated amputations and mortality are directly related to the severity of injury, or indirectly to delay in diagnosis and treatment of the compartment syndrome and its complications.

AIDS in the elderly: a case and its implications.

Although acquired immunodeficiency syndrome (AIDS) remains relatively uncommon in the elderly, there are serious and unique implications associated with the diagnosis of AIDS in this age group. The most common mode of transmission is transfusion. With the growing number of elderly, an increase in AIDS in the elderly will occur despite improved screening methods. Dementia is a serious morbidity associated with AIDS in the elderly, which presents considerable diagnostic and ethical dilemmas. A case is presented which illustrates the geriatric multidisciplinary team approach to the care of a 90-year-old man with AIDS.

Addiction.

Addiction to tobacco, alcohol and drugs is a major problem. Dependence and problem drug use are now defined syndromes and their psychological, genetic and brain mechanisms are being elucidated. Social policy can influence the consumption of drugs and treatment strategies are becoming more effective.
