In the summer quarter of 1963 (July-September), the number of acute conditions involving one or more days in bed declined seasonally to 14 cases per 100 persons in the population. Respiratory conditions accounted for 6.1 acute cases per 100 population, 2.6 cases were infectious and parasitic conditions, and 0.9 cases were conditions of the digestive system.

Statistics from the U. S. National Health Survey health interview are based on a continuing sample of the civilian, noninstitutional population residing in the United States. Estimates are based on interviews of a minimum of 36,000 households containing approximately 115,000 persons per year. Each statistic is adjusted to official U.S. Bureau of the Census population figures to make the sample estimates closely representative of the total population by age, sex, color, and residence. 1 Annual data are for twelve month periods, ending June 30 of the years shown. 2/ Except for a list of chronic conditions that are excluded regardless of duration (as specified in the interview schedule reproduced in all Series B and Series 10 publications), acute conditions are those originating during the two weeks prior to the week of interview, and are accumulated to provide quarterly or annual estimates.

ACCIDENTS During the summer quarter of 1963, approximately 15.6 million persons were injured in accidents causing one or more days of restricted activity or requiring medical attention, in comparison to 14.1 million persons during the summer quarter of 1962. Of the 27 persons per 100 population who experienced accidents during the year ending September 30, 1963, 12 persons were injured in the home, 4 were injured at work, and 11, in motor vehicle and all other types of accidents.

"While at work" includes all accidents occurring while the person was at work at his job or business, except those accidents involving motor vehicles (which are included in the "all other" accident category). "Home" includes all accidents occurring in any home or premise of a home except those accidents classified as "motor vehicle" or "work."' 2/ Sampling errors on estimates for a single quarter or for a change between two quarters are large. Hence attention should be focused on long-term trends from a sequence of quarters and not on the difference between quarterly estimates.

ABSENCE DUE TO ILLNESS OF EMPLOYED CIVILIANS AND MILITARY PERSONNEL

During October 1.4 million employed persons, or 1.95 percent of the working civilian population, were absent from work on an average day because of illness. This percentage was somewhat higher than the October 1962 rate. The illness absenteeism rate for military personnel increased slightly during September to .88 percent.

PATIENTS IN STATE AND LOCAL GOVERNMENT MENTAL HOSPITALS

The number of resident patients in State and local Government mental hospitals at the end of September (500,400) was 2.6 percent below the number in these hospitals one year earlier. During the first nine months of 1963, admissions increased by 5.9 percent; net releases, by 9.0 percent, and deaths, by 1.4 percent over the corresponding period of 1962.

The Model Reporting Area (PHS Pub. 699, 1959) includes definitions and tabulations required of member States. Data are for end of period; annual data are for fiscal years, which end on June 30 for most public hospitals. Monthly estimates for continental United States were made on the basis of data submitted by 25 States through June, 1960 and by approximately 30 States thereafter. Patients in the public mental hospitals of these States account for about five-sixths of the resident patient population in all public mental hospitals in the U. S.; annual rates for these states very dosely parallel those for the U. S. 2/ The resident patient population at end of period equals resident patients at beginning of period plus admissions minus net releases 3/ Direct discharges plus placements on extramural care minus returns from extramural care. Patients out for the Christmas-New Year holiday period (more than 7 days) are considered as releases in December and returns in January. 4 Monthly rates are based on monthly estimates of the civilian population for the States reporting but are shown on an amual basis with adjustment for number of days in the month.
