A pilot study of infectious intestinal disease in England.

Pilot studies to test methods to determine the incidence, agents, risk factors and socioeconomic costs of infectious intestinal disease (IID) in England were carried out as recommended by the Committee on the Microbiological Safety of Food (the Richmond Committee) by eight general practices. There were case control and enumeration studies of patients presenting to general practice with IID, a population-based prospective cohort study, and a survey of socioeconomic costs of cases of IID. Information on risk factors was obtained by questionnaire (self-administered compared with interview) and a stool sample was requested on all cases and controls. Response rates in the GP case control study were 75% for case questionnaires and 74% for stools; for controls the figures were 70% and 68% respectively. The acceptance rate into the cohort study was 49%; this was significantly higher where phone contact was made. The rate was similar if recruitment was by individual or household. Follow-up of the cohort by negative reporting was complete for up to 6 months. Direct postage by subject was required to obtain fresh stool specimens. Estimates were obtained of presentation rates of IID and the distribution of risk factors which were used to plan the main study. The pilot study demonstrated that it is possible to undertake a national study based in general practice to determine the incidence of IID in the population and presenting to GPs and its agents, risk factors and costs.

Cigarette smoking by socioeconomic group, sex, and age: effects of price, income, and health publicity.

OBJECTIVE: To assess effects of price, income, and health publicity on cigarette smoking by age, sex, and socioeconomic group. DESIGN: Econometric multiple regression analysis of data on cigarette smoking from the British general household survey. SUBJECTS: Random sample of adult population in Britain interviewed for biennial general household surveys 1972-90. MAIN OUTCOME MEASURES: Changes in cigarette consumption and prevalence of smoking. RESULTS: Price elasticities of demand for cigarettes (percentage change in cigarette consumption for a 1% change in price) were significant at -0.5 (95% confidence interval -0.8 to -0.1) for men and -0.6 (-0.9 to -0.3) for women, were highest in socioeconomic group V (-1.0 for men and -0.9 for women), and lowest (not significantly different from zero) in socioeconomic groups I and II. The gradient in price elasticities by socioeconomic group was significant for men (F = 5.6, P = 0.02) and for women (F = 6.1, P = 0.02). Price was a significant factor in cigarette consumption by age for women in every age group and for men aged 25-34. Cigarette consumption by young men aged 16-34 increased with income. There was a significant decrease in smoking over time by women in socioeconomic groups I and II and by men in all age and social groups except socioeconomic group V attributable to health publicity. Price significantly affected smoking prevalence in socioeconomic group V (-0.6 for men and -0.5 for women) and for all women (-0.2). CONCLUSIONS: Men and women in lower socioeconomic groups are more responsive than are those in higher socioeconomic groups to changes in the price of cigarettes and less to health publicity. Women of all ages, including teenagers, appear to have been less responsive to health publicity than have men but more responsive to price. Response to health publicity decreased linearly with age. Real price increases in cigarettes could narrow differences between socioeconomic groups in smoking and the related inequalities in health, but specific measures would be necessary to ameliorate effects on the most deprived families that may include members who continue to smoke. The use of a policy to steadily increase cigarette tax is likely to help achieve the government's targets for smoking and smoking related diseases.

Is housing a public health issue? A survey of directors of public health.

OBJECTIVE: To determine the views of directors of public health on the importance of housing for public health and their departments' and health authorities' participation in housing issues. DESIGN: Postal self administered questionnaire survey. SETTING: All district health authorities in England and health boards in Wales, Scotland, and Northern Ireland. SUBJECTS: All 221 district directors of public health in England and chief administrative medical officers in Wales, Scotland, and Northern Ireland. MAIN OUTCOME MEASURE: Response to questionnaire consisting of fixed and open ended questions on housing issues. RESULTS: The response rate was 89% (196/221). Housing was perceived as a major health problem by 33% (65/196) of directors. Positive responses were most likely from inner city districts. In 47% (93/196) of departments there was a formal time commitment to housing issues with a median time of one session/week (range one per month to 10 per week). The main function was allocation of medical priority for public sector rehousing. Overall, 73% (144/196) reported some participation in this process. Reported participation in joint care planning and links with non-statutory housing organisations were uncommon. 53% (104/196) of directors had included housing issues in their annual health report. In 16% (32/196) of districts specific services for the homeless had been set up. CONCLUSIONS: Although concern about the impact of current housing policy on public health was shown by a substantial number of directors, the main activity was still allocation of medical priority despite a background of increasing housing need and homelessness. The underlying need is for greater advocacy to produce a healthy housing policy for all, and the annual public health report could be used to promote this objective.

Obstetric outcome in homeless women.

OBJECTIVE: To characterise the pregnant homeless population booking and delivering at St Mary's Hospital, London, and ascertain whether their obstetric outcome was adversely affected by their homeless condition. DESIGN: Retrospective comparison of demographic characteristics of 185 homeless women booking for delivery with those of housed women booking in the same period and with the population of North West Thames region; comparison of obstetric performance of homeless women with subgroup of the housed population (group matched for age, parity, and ethnic origin). SETTING: Consultant obstetric unit, St Mary's Hospital, London. SUBJECTS: All women booking between April 1987 and March 1988 who subsequently had a registrable birth. MAIN RESULTS: 185 (8%) Of the 2308 women studied were homeless. Compared with the housed population, they had a larger proportion of young women, women of high parity, and Indo-Pakistani women and a smaller proportion of primiparas. Homeless women booked later and had had more previous obstetric problems than housed women. Pregnancy outcome (assessed by birth weight and prematurity rates) was worse than that of both women housed locally and the regional population. Antenatal attendance, complications, intrapartum performance, and perinatal outcome of homeless women did not differ from those in the control group. CONCLUSIONS: This study has been unable to show any significant differences in the outcome of pregnancy in homeless women that can be directly attributed to living in bed and breakfast accommodation, but these women have sociodemographic characteristics and obstetric risk factors that contribute to a poorer outcome in pregnancy than for the general population.

Developing care in the community: GPs and the HIV epidemic.

Services for HIV infection and AIDS in Parkside DHA have been largely hospital based with little active involvement of local GPs. In response to the wishes of those with HIV/AIDS and predicted increases in the number of patients the DHA is now developing an AIDS strategy which identifies the development of primary and community care as a major objective. A postal survey of all 263 GPs within the DHA was undertaken in order to ascertain their views about the role of primary care in the management of HIV infection/AIDS. Replies were received from 75% (196). The responses to the survey indicated both the potential of general practice and willingness of GPs to be involved in the care of this client group. However, two key issues in developing this strategy were identified. These were information exchange and confidentiality. It is suggested that both hospitals and general practice must develop rigorous confidentiality policies to overcome these difficulties.

Use of hospital services by homeless families in an inner London health district.

Over the past decade the number of families in London who were considered officially to be homeless appreciably increased. In response to this many families have been given temporary accommodation, usually in bed and breakfast hotels, while awaiting permanent rehousing. About 200 of the roughly 600 hotels in London that provide such accommodation are located in the area of the former Paddington and North Kensington Health Authority, now part of Parkside Health Authority. The use made by the homeless population of hospital services was studied by finding out the numbers of inpatients admitted to hospital and the numbers presenting to the walk in paediatric clinic and the casualty department at one hospital. These figures were compared with those for local residents and the overall workload. The bed and breakfast population were high users of inpatient beds, the casualty department, and the paediatric clinic. Overall, about one tenth of the beds were used by these people. The health authority receives no additional funding for this group of patients. Further research is needed to find out if the high use of hospital services made by these patients reflects their increased morbidity or their inability to obtain primary care services.

A myelokathexis-like variant of myelodysplasia.

A 34-year-old woman presented with pancytopenia, profound neutropenia and repeated infections. A bone marrow specimen revealed hypercellularity with trilineage dysplasia and bizarre granulocytic morphology identical to that of the rarely reported myelokathexis. Investigations revealed defects in platelet and neutrophil functions and markedly reduced colony-to-cluster ratio in bone marrow culture. She required treatment with antibiotics, surgical intervention for a gangrenous abdominal wall, and eventually underwent a successful allogeneic bone marrow transplant from her sister. This case suggests that myelokathexis is an unusual form of myelodysplasia with a relatively benign course and presenting at a young age.
