Nonfatal suicide attempts and other self-inflicted harm. Beltrami County youths, 2002-2006.

Following a highly publicized murder-suicide by a high school student in Beltrami County, Minnesota, the Minnesota Department of Health initiated an investigation into suicide attempts and self-inflicted harm (SA/SIH) among youths in the county between 2002 and 2006. This article summarizes the results of that effort, which found an annualized rate of 356 hospital-treated SA/SIH per 100,000 population among Beltrami County residents ages 10 to 24 years--a rate more than 50% higher than that of other youths in Minnesota or the United States. In addition, the rate of SA/SIH for American Indian youths in Beltrami County was 2.5 times higher than that for white youths. An examination of medical history found 52% of the youths in this study had previously attempted suicide. This article also discusses several modifiable risk factors that were identified and potential interventions.

Predicting trauma admissions: the effect of weather, weekday, and other variables.

One of the challenges all hospitals, especially designated trauma centers, face is how to make sure they have adequate staffing on various days of the week and at various times of the year. A number of studies have explored whether factors such as weather, temporal variation, holidays, and events that draw mass gatherings may be useful for predicting patient volume. This article looks at the effects of weather, mass gatherings, and calendar variables on daily trauma admissions at the three Level I trauma hospitals in the Minneapolis-St. Paul metropolitan area. Using ARIMA statistical modeling, we found that weekends, summer, lack of rain, and snowfall were all predictive of daily trauma admissions; holidays and mass gatherings such as sporting events were not. The forecasting model was successful in reflecting the pattern of trauma admissions; however, it's usefulness was limited in that the predicted range of daily trauma admissions was much narrower than the observed number of admissions. Nonetheless, the observed pattern of increased admission in the summer months and year-round on Saturdays should be helpful in resource planning.
