Injury fatalities among young children.

Injuries and violence are the primary causes of death among young children in the United States. In particular, in 1982-84 motor vehicle injuries, fires, drowning, and homicide were the leading external causes of death at ages 1-4 years and 5-9 years, accounting for nearly 80 percent of all deaths from external causes. The purpose of this article is to analyze race and sex differentials in injury fatalities among young children. Race and sex differentials in injury mortality were measured in terms of relative risks, that is, race (black to white) and sex (male to female) mortality ratios. Race ratios for external causes ranged from 1.7 to 1.9 for children 1-4 and 5-9, while sex ratios were somewhat lower, 1.4 to 1.8. Although race and sex ratios were relatively small for passenger-related motor vehicle fatalities (0.8 to 1.2) the ratios for pedestrian-related injuries were considerably greater (1.5 to 2.0). Race ratios for deaths caused by fires and homicide were particularly large (3.4 to 4.3). Mortality differences were also measured in terms of excess mortality. For each age-race group more than 65 percent of the overall excess deaths among males were due to external causes of death. Pedestrian-related motor vehicle injuries and drownings accounted for the largest proportion of excess deaths among males. At ages 1-4, 53 percent of the overall excess deaths among blacks were due to external causes. Deaths caused by fires and homicide accounted for more than two-fifths of the excess in this age group. At ages 5-9, 81 percent of excess mortality among black males and 69 percent among black females were accounted for by external causes. Fires, pedestrian-related motor vehicle fatalities, and homicides accounted for nearly 65 percent of excess mortality among black children.There has been a 30 percent decline in death rates from all external causes between 1972-74 and 1982-84. Pedestrian-related motor vehicle death rates declined the most in both age groups.Mortality also declined in each age-race-sex group for passenger-related motor vehicle injuries, for drownings, and for fires except among black males ages 5-9. Homicide, in contrast, increased in both age groups. There has been little change, however,in the incidence of injuries among children. Thus,it appears that declines in fatalities accounted for a major portion of the mortality reduction.

National health and nutrition examination I--epidemiologic follow-up survey.

An epidemiologic follow-up of the first National Health and Nutrition Examination Survey (NHANES I), being conducted from 1982 to 1984, is expected to provide estimates of the risks of certain health conditions for a sample of the U.S. population and to make it possible to relate these conditions to the nutritional, social, demographic, and behavioral characteristics of the sample. As part of the followup study, the baseline data obtained in NHANES I have been reviewed to define hypotheses and to identify pertinent variables that can be used in studying changes over time and the relationships of these variables to outcome measures. Because the followup study provides cohort data on a large sample of the U.S. population, it presents a unique opportunity for epidemiologists.

Planning for emergency medical services in Boston.

The results of a survey of 10,200 visits to 11 Boston hospital emergency rooms during a 9-day period in March 1972 are presented. The survey was designed to provide data on emergency room use to permit more informed planning by public agencies concerned with improving areawide emergency medical services. The 11 institutions surveyed provided virtually all of the emergency medical services in the city of Boston. A majority are teaching hospitals affiliated with one or more of the three medical schools in the area. Of the 11 hospitals, 3 accounted for 60% of all emergency room visits. Survey data were extracted from emergency room log sheets and hospital medical records of individual patients. Information collected included the residence pattern of patients within the geographic area, the patient mix by degree of urgency based on presenting complaints, mode of transportation to the hospital, and age and sex of the patients. Only 15 percent of the 10,200 visits were true emergencies. Fifty-seven percent were classified as urgant and 28% nonurgent. The mix among the 11 hospitals ranged from 7 to 22 percent in the emergency category, and 11 to 61 percent in the nonurgent classification. Trauma accounted for 19 percent of all admissions, with 3 percent attributed to fractures and 4 percent to head injuries. Fifty-six percent of the emergency cases required the services of an internist or pediatrician, 38 percent a surgeon, and 1 percent an obstetrician. The highest utilization rate--27 per 1,000 population--was recorded for the under 5 age group. Although the 65 and older age group had the lowest utilization rate of 6 per 1,000, this group had the highest rate of visits classified as emergencies. Children under 5 accounted for the highest proportion of nonurgent visits. The survey revealed that 30 percent of all hospital admissions were from the emergency room. One in four emergency patients lived outside the city of Boston. A neighborhood health center and a hospital general practice unit reduced hospital emergency room workloads appreciably, even when they were open only during daytime hours. Eighty-eight percent of all patients arranged for their own transportation, usually by private automobile. Of those arriving by ambulance, only 35 percent were classified as emergencies. The survey data reinforce the conclusion that major planning efforts should be concentrated on the management of the nonemergency patient. The data also emphasize the need for a single agency to be responsible for overall planning for emergency medical services on an area wide basis.
