Under the provisions of the Massachusetts Law "No person suffering from insanity, mental derangement, delirium or mental confusion, except delirium tremens and drunkenness, shall, except in case of emergency, be placed or detained in a lockup, police station, city prison, house of detention, jail or other penal institution, or place for the detention of criminals. If, in case of emergency, any such person is so placed or detained, he shall forthwith be examined by a physician and shall be furnished suitable medical care and nursing and shall not be so detained for more than twelve hours." In Boston these cases are sent to the Psychopathic Hospital. In other parts of the state they are cared for by the board of health of the city or town in question until they can be committed to a hospital or cared for by relatives or friends. The superintendent of a state hospital, under the authority of chapter 123 of the General Laws, "When requested by a physician, by a member of the board of health or a police officer of a city or town, by an agent of the institutions registration department of the city of Boston, or by a member of the district police 'may' receive and care for in such hospital as a patient, for a period not exceeding ten days, any person who needs immediate care and treatment because of mental derangement other than delirium tremens or drunkenness." Such cases are received on application in writing filed at the time of the reception of the patient or within twenty-four hours thereafter and must be discharged or committed within ten days unless they make a request for voluntary care. During 1920 there were 1,929 temporary care cases reported by the various Massachusetts state hospitals, as follows: Boston State Hospital (Psychopathic Department) 1,049, Danvers 217, Northampton 188, Worcester 159, Taunton 154, Westborough 68, Foxborough 56, Medfield 33, Grafton 2, and Gardner State Colony 3. Nowhere else in the country has this particular form of legislation been used so extensively. It is something more than a mere authorization for the reception of mental cases in observation or detention wards. Under its provisions, at the request of any reputable practicing physician and without further legal formalities, mental cases may be cared for in a state hospital until their condition can be definitely determined and arrangements made for their proper disposition and treatment. The criticism to which this plan is open is that the period of time, ten days, is not long enough. It should be extended to thirty days at least.
