BACKGROUND: The prevalence of ischemic heart disease (IHD) has been declining in North America since the 1960s. Over this time, Native populations, which have traditionally had low rates of IHD, have undergone striking lifestyle changes that may have had health consequences. In this context, IHD trends in the Native communities of Ontario, Canada, were evaluated. OBJECTIVE: To assess trends in admission rates for IHD in the Native population of Ontario compared with the general population of Ontario. METHODS: A comprehensive administrative database of all hospital admissions in Ontario 1981 to 1997, was used. Age- and sex-adjusted rates of hospital admissions with IHD-related diagnostic or procedure codes were determined in all residents of Ontario communities that had regular census participation and at least 95% of their population claiming Native origins (N=16,874 in 1991). Comparison was made with all residents of the surrounding northern Ontario region (N=822,450) and of the whole province (N = 10,084,885). RESULTS: In 1981, the rate of IHD admissions was similar in all groups, at 99 to 124 per 10,000 persons. By 1997, it decreased to 82 per 10,000 in the province (slope, -1.09; 95% confidence interval, -1.26 to -0.91), with a similar trend in northern Ontario. However, in the Native communities, it increased to 155 per 10,000 (slope, 5.6; 95% confidence interval, 3.8-7.5). A similar trend was seen for acute myocardial infarction admissions, a more precisely coded subset of IHD. Spurious causes of increasing rates were ruled out. CONCLUSIONS: Hospitalizations for IHD have doubled in the Native population despite declining rates in the general population. These findings document an alarming trend in Native health and support the need for further research and targeted intervention.

BACKGROUND: Lengths for hospital stays for people with serious mental illness have reduced drastically over the last 30 years. Some argue that this reduction has led to revolving door admissions and worsening mental health outcomes despite apparent cost savings, whilst others suggest longer stays may be more harmful in the long term by institutionalising people to hospital care. This review attempts to answer which is the answer: whether short or long stays are effective. OBJECTIVES: To determine the effect of planned short stay admission policies versus a long or standard stay for people with serious mental illnesses. SEARCH STRATEGY: Biological Abstracts (1982-1995), Cochrane Schizophrenia Group's Register (December 1998), EMBASE (1980-1998), MEDLINE (1966-1998) and PsycLIT (1974-1995) were searched. Further references were sought from published trials and their authors. SELECTION CRITERIA: All randomised trials of planned short versus long hospital stays for people with serious mental illness (however defined). DATA COLLECTION AND ANALYSIS: Trials were reliably identified and data extracted. Analysis was on an intention-to-treat basis. People who dropped out or lost to follow-up were assumed to have no improvement. Peto odds ratios (OR) and 95% confidence intervals were calculated. MAIN RESULTS: Five randomised controlled trials were included. For those receiving planned short stays, data suggested that this group experienced no more re-admissions (OR 1.1, CI 0.7-1.7), no more losses to follow up (OR 1.09, CI 0.6-1.9), and were more successfully discharged on time (OR 0.47, CI 0.3-0.9) compared to long stay or standard care. The data also suggested some evidence that planned short stay patients were no more likely to leave hospital prematurely and had a greater chance of being employed. Data on mental, social and family outcomes could not be summated and there was little or no data on user satisfaction, deaths, violence, criminal behaviour, and costs. REVIEWER'S CONCLUSIONS: The effects of hospital care and the length of stay is important for mental health policy. This review suggests that a planned short stay policy does not encourage a 'revolving door' pattern of admission and disjointed care for people with serious mental illness. More large, well-designed and reported trials are justified. It may be that the 'developing world', where, in some places, the long stay institutions are still functioning, will be able to provide good data that has failed to appear from research in the 'developed world'.
