Trends In Hospital Admissions Research Articles

Trends in hospital admissions and death rates for peptic ulcer in the United States from 1970 to 1978

During the period 1970–1978, admissions to short-term nonfederal hospitals in the U.S. for duodenal ulcer decreased by 43%, whereas admissions for gastric ulcer did not change significantly. The decline in admissions for duodenal ulcer was greatest for uncomplicated cases, less for those with hemorrhage, and least (and not significant) in those with perforation. During the period 1970–1977, U.S. Vital Statistics reports of deaths from peptic ulcer decreased 31%, with about equal declines in total deaths, those associated with hemorrhage, and those associated with perforation. The fall in death rate involved both gastric and duodenal ulcer in both men and women. The male/female ratio has been falling steadily, and now stands at about 1.2 for hospitalizations and about 1.5 for deaths. From 1970 to 1978 the percentage of persons over 60 yr of age rose from 14 to 15% in the U.S. population as a whole, from 23 to 29% in persons hospitalized for all causes, from 27 to 36% in those hospitalized for duodenal ulcer, and from 40 to 48% in those hospitalized for gastric ulcer.

Self-poisoning and suicide due to paracetamol.

Introduction .Self-poisoning from all causes is now an extremely common problem which may. account for over 10% of acute medical admissions to hospital (Matthew & Lawson 1975). Very few self-poisonings, however, result in death and the overall mortality rate from medicines and other noxious substances either in hospital or out of hospital is less than 3 per 100 self-poisonings and is not increasing (Registrar General's Statistical Review). With the Registrar General's Statistical Review as the principal source of information an attempt has been made to review the recent trends in both hospital admissions due to self-poisoning and in deaths due to drugs. From this it is hoped to sketch briefly the overall background to the problem of selfpoisoning and to focus in detail on the findings related to mild analgesics.

Investigation of Relation between Use of Oral Contraceptives and Thromboembolic Disease. A Further Report

The results of a previous study of the use of oral contraceptives by married women discharged from hospital with a diagnosis of thromboembolic disease in the years 1964-6 were reported by us last year. The present paper adds results relating to patients discharged during 1967 and a few data, that could not be sought previously, for patients discharged with cerebral or coronary thrombosis from three of the hospitals in the earlier period.Of 84 patients with deep-vein thrombosis or pulmonary embolism 42 (50%) had used oral contraceptives during the month preceding the onset of their illness, while only 23 of the 168 controls (14%) had done so. No differences in risk were found either for the types of preparation or for the duration of use. After allowance for age and height, the patients with venous thromboembolism were about 10 lb. (4,535 g.) heavier than the control patients, irrespective of whether they were using oral contraceptives or not. No appreciable difference was found between the smoking habits of patients with and without venous thromboembolism treated during 1967, nor between women who were using oral contraceptives and those who were not. The trend in hospital admissions for venous thromboembolism with time corresponded to the trend in the use of oral contraceptives, and there was no evidence to suggest that the number of admissions was affected by publicity about the risk of using the preparations. Of 19 patients with cerebral thrombosis 11 (58%) had been using oral contraceptives, compared with an expected figure of 3.5 from the experience of the control subjects. All the published data (clinical, angiographic, and post-mortem) show that the thrombosis affects the cerebral arteries rather than the cerebral veins. Of 17 patients with coronary thrombosis 2 (12%) had been using oral contraceptives, compared with an expected figure of 2.1. The patients with coronary thrombosis smoked more than the control patients and were, on average, 8.3 lb. (3,765 g.) heavier than control women of the same age and height.The new evidence strengthens the belief that oral contraceptives are a cause of venous thromboembolism and cerebral thrombosis but does not indicate that they are a cause of coronary thrombosis.

Recent Critical Trends in Mental Hospital Admissions in the Oxford Region

The statistics on mental hospitals published by the Ministry of Health (1957) show that the average length of stay for admissions to mental hospitals decreased in the period 1952–1956. According to the Registrar-General's Mental Health Supplement (1961) there was an average saving, between 1951 and 1958, of sixteen days for men and thirteen days for women, among patients staying less than one year. But these figures for stay only relate to the patients discharged each year, irrespective of the year of their admission, and furthermore we do not know what happens to particular groups such, for example, as schizophrenics. Although remarkable changes are occurring at the present time, study of them is hampered by lack of appropriate and up-to-date information.
