will, I think, be conceded. For statistical purposes, at least, it may be assumed that the frequence of mental diseases as shown by a study of the hospital population is fairly representative of conditions existing in the community.
For purposes of comparison we may contrast the admission rate of mental diseases per 100,000 of the population in Massachusetts in 1920 with the case rate of communicable diseases as follows:
| Mental diseases | 101.7 |
| Chicken pox | 138.4 |
| Diphtheria | 194.2 |
| German measles | 12.5 |
| Gonorrhea | 186.7 |
| Measles | 830.7 |
| Mumps | 154.1 |
| Scarlet fever | 265.2 |
| Syphilis | 77.2 |
| Tuberculosis, pulmonary | 173.1 |
| Tuberculosis, other forms | 20.7 |
| Typhoid fever | 24.2 |
| Whooping cough | 258.3 |
The total institution population (mental cases) at the end of the year 1920 represented a rate of 395.49 per 100,000 of the population. It should be borne in mind that, with the exception of tuberculosis and syphilis, the communicable diseases reported above represent, as a rule, the total number of cases in the state during the year. Comparative studies should, therefore, be based not on the number of mental cases in the hospitals at any one given time, but on the total number under treatment during the year. This would indicate an incidence of mental diseases of 566.98 per 100,000 of the population.
On January 1, 1916, there were 147 state and federal institutions for the care and treatment of mental diseases in the United States, as shown by the Census Bureau reports. There were at this same time twenty-seven institutions for the feebleminded, nine for epileptics, three for inebriates, forty-five for tuberculosis, twenty-eight for the blind, thirty-three for the deaf, twelve for the blind and deaf and eighty-four for the dependent classes. [3]
The appropriations for the maintenance of these institutions for 1915 amounted to $33,557,058.29. This constituted 7.6 per cent of the appropriations made by those states for all purposes. In Massachusetts it represented 14.8 per cent, in New Hampshire 10.1, in New York 12.7, in Ohio 12, in Indiana 10.7, in Illinois 13.4, and in a number of other states over ten per cent of the appropriations for all purposes. It was equivalent to an average of $431.16 per million of the total assessed valuation of these states. In Massachusetts it was as high as $653.62 and in New York $567.37. This means thirty-three cents per capita for all states, eighty-four cents for Massachusetts and sixty-eight cents for New York.
The actual expenditure for the maintenance of these institutions was $36,312,662.20. For purposes of comparison, attention should be called to the fact that the maintenance of the tuberculosis hospitals of the United States for the same year cost $3,539,454.95, institutions for criminals $21,244,892.00, for the feebleminded $3,341,442.85, for epileptics $1,345,821.57, for the blind $1,066,973.14, for the deaf $1,893,490.09 and for the dependent classes $9,675,932.37.
The value of the property invested in the state and federal hospitals for mental diseases in 1916 was estimated at $187,028,728.00. The valuation of these institutions per 100,000 of the population was $184,795.81. This does not include establishments for mental defectives. The average value per patient was $938.43. In Massachusetts it was $1,097.85 and in New York $1,039.85. In Arkansas it was as high as $2,264.00. The total acreage of land was 109,503.2, an average of 744.9 acres per hospital. There were 33,124 persons employed, an average of 226.9 for each institution. This represented one employee for every six patients.
The census taken by the National Committee for Mental Hygiene [4] in 1920 shows 156 state hospitals for mental diseases, two federal institutions, 125 county or city hospitals and twenty-one institutions of a temporary care type. In the public and private hospitals for mental diseases on January 1, 1920, there were 232,680 patients under treatment. Of these, 200,109 were in public and 9,238 in private hospitals. This represented an increase of 8,723 in two years. It is interesting to note that city and county institutions cared for 21,584 persons.
The first authoritative information relative to the institution care of mental diseases was obtained from the federal census reports of 1880. In that year there were 40,942 patients in the public hospitals. In 1890 there were 74,028; in 1904, 150,151; in 1910, 187,791; in 1917, 232,873 and in 1918, 239,820. The rate per 100,000 of the population increased from 81.6 in 1880 to 229.6 in 1918. From 1910 to 1918 the general population increased 13.6 per cent and the hospital population 27.7 per cent. The rate per 100,000 of the population in institutions in Massachusetts[5] on January 1, 1920, was 373.8, in New York 374.6, in Connecticut 317.8, in Iowa 248.1, in Wisconsin 300.6, in California 297.2, in Pennsylvania 215.2, in Ohio 212.1, in Illinois 229.5 and in Michigan 210.8. The admission rate per 100,000 of the population in 1917 was 151.6 in Massachusetts, 109.2 in Illinois, 124.8 in Montana, 97.3 in New York, 80.9 in Connecticut and 85.7 in California.
The cost of maintenance in the state hospitals increased to $43,926,888.88 in 1917 with an average per capita cost of $207.28. The number of cases cared for in some of the more populous states is of interest. On January 1, 1920, the institution population of New York was 38,903, Pennsylvania 18,764, Ohio 12,217, Illinois 14,884, Massachusetts 14,399 and California 10,184.
Based on the estimated population of Massachusetts on July 1, 1920 (3,869,098), the 1,475 deaths in institutions for mental diseases would represent a death rate of 38.12 per 100,000 of the population. The death rate for other diseases for that year was: diphtheria 15.4, measles 9.0, pulmonary tuberculosis 96.7, typhoid fever 2.5, whooping cough 14.0, scarlet fever 5.5, syphilis 5.8, lobar pneumonia 71.9 and influenza 43.9. The importance to be attached, however, to such comparisons is very uncertain at best. From the standpoint of social and economic importance to the community there is another factor under consideration which should not be overlooked. The duration of other diseases, as a general rule, is comparatively short. A study of over ten thousand deaths in New York state hospitals for mental diseases shows the average hospital residence of these cases to have been over six years. At the rate of admission to public institutions for 1917 (62,898) and the average per capita cost for that year ($207.28) the care of persons admitted annually, during their years of hospital life, would mean an expenditure of over seventy-eight millions of dollars.
If we figured the earning capacity of the 62,000 persons admitted to institutions for mental diseases in the United States as averaging only one thousand dollars per year, it would represent an economic loss to the country of sixty-two millions of dollars annually. Estimated in the same way, the total population of the hospitals would represent the staggering sum of nearly two hundred and forty million dollars. This, of course, does not take into consideration at all the cost of maintenance or the property investment represented by hospitals.
To avoid any possibility of confusion, no reference has been made heretofore to statistical studies of mental deficiency or epilepsy. From a public health point of view, however, and as social and economic problems, they are questions which cannot be disregarded in a consideration of mental diseases. As a matter of fact, they are very closely correlated in many ways. A survey made by the National Committee for Mental Hygiene shows that on January 1, 1920, there were in this country thirty-two state institutions for mental defectives, eleven admitting both feebleminded and epileptics and twenty exclusively for the latter class. [6] In addition to this, one city institution was reported. Of the private hospitals twenty-seven care for the feebleminded only, and six for epileptics, while nineteen admit either of these classes. The total number of mental defectives in institutions on January
