“The number of visits required must depend upon the circumstances of each particular case, and the physician is regarded by the law as the best and proper judge of the necessity of frequent visits; and, in the absence of proof to the contrary, it will be presumed that all professional visits made were deemed necessary and were properly made.

“There must not be too many consultations. The physician called in for consultation or to perform an operation may recover his fees from the patient, notwithstanding that the attending physician summoned him for his own benefit, and had arranged with the patient that he himself would pay.” (This, of course, does not mean that the practitioner has a right thus to shift the burden of pay from his own shoulders.) “Where a medical man has attended as a friend, he cannot charge for his visit. Where a tariff of fees has been prepared and agreed to by the physicians of any locality, they are bound by it legally as far as the public are concerned (that is to say, they cannot charge more than the tariff rates), and morally as far as they themselves are concerned” (p. 5).

In these rules Dr. Ewell regards chiefly what conduct the courts of justice will sustain. It is evident that the Doctor is never entitled to run up his bill without any benefit to his patient; where there is no service rendered at all, there can be no claim to compensation. Still it is not necessary that actual benefit has resulted to the patient; it suffices for the claim to the fee that measures have been taken with a view to such benefit. Even when no physical advantage can reasonably be hoped for from the visit, the consolation it affords the patient and his friends may render those who are to bear the expense fully willing that it should be often repeated and, of course, charged on the bill. Provided care be taken that they understand the situation, no injustice is done them. “Scienti et consentienti non fit injuria” is a good moral maxim.

II. We have said that the rights conferred on the physician by the state are conditioned on his performing certain duties. He owes the same duties to his patients in virtue of the contract, explicit or implicit, that he makes with them by taking the case in hand. Under ordinary circumstances, neither the state nor the patients can oblige him to exercise his profession at all; but, if once he has taken a case in hand, he can be justly held not to abandon it till he has given his patient a fair opportunity of providing another attendant; even the fear of contagion cannot release him from that serious obligation.

The duties arising from the physician’s twofold contract, with the state and with his patients, are chiefly as follows:

1. He must acquire and maintain sufficient knowledge of his profession for all such cases as are likely to come in his way. No Doctor has the right to attempt the management of a case of which he has not at least ordinary knowledge. In matters of special difficulty, he is obliged to use special prudence or ask for special consultation. The courts justly hold him responsible for any serious injury resulting from gross ignorance; in such cases they will condemn him for malpractice. I would here remark that, in an age in which the science of medicine is making such rapid progress, every Doctor is in duty bound to keep up with the improvements made in general practice, and in his own specialty if he has one.

2. A second duty is that of proper diligence in treating every single case. Many a patient suffers injury to health or even loses his life in consequence of a Doctor’s neglect. Gross negligence is an offence that makes him punishable by the court, if it results in serious injury. But even if such injury cannot be juridically proved, or has been accidentally averted, the moral wrong remains and is to be settled with the all-seeing Judge. Still, in ordinary ailments, no one is obliged to take more than ordinary trouble.

3. A third duty of the physician is to use only safe means in medical and surgical practice. He has no right to expose his patient to needless danger. What is to be thought of the use of such remedies as will either kill or cure? They cannot be used as long as safer remedies are available and capable of effecting a cure; for neither Doctor nor patient has a right to expose a human life to unnecessary risk. But when no safer remedies are going to effect a cure, then prudence itself dictates the employment of the only means to success. In such a case, however, the patient, or his parents or guardian, should, as a rule, be informed of the impending danger, so that they may give or refuse their consent if they please. For, next to God, the right to that life belongs to them rather than to the physician. The same duty of consulting their wishes exists when not life but the possible loss of a limb is at stake, or the bearing of uncommon sufferings. Moralists teach that a man is not obliged in conscience to submit to an extraordinarily painful or revolting operation even to save his life. Certainly, when the natural law leaves him at liberty, the physician cannot compel him to submit to his dictation; all he can do is to obtain his consent by moral persuasion.

4. As a consequence from the Doctor’s duty to use only safe means it follows that he cannot experiment on his patients by the use of treatment of which he does not know the full power for good or evil. Nor is he excused from responsibility in this matter by the fact that the experiment thus made on one patient may be very useful to many others. His contract is with the one now under treatment, who is not willing, as a rule to be experimented upon for the benefit of others. And even if the patient should be willing, the Doctor cannot lawfully expose him to grievous danger unless it be the only hope of preserving his life. This follows from the principle explained before, that human life belongs chiefly to God and not to man exclusively.

5. There are various kinds of medical treatment to which we can scarcely have recourse without exposing ourselves to serious evil consequences. Such is the use of cocaine, morphine, and even in special cases of alcohol. The drugs in themselves are useful, but they often lead to evil results. Now in the use of all such drugs as are apt to be beneficial in one way and injurious in another, we must ever be guided by the rules formerly explained concerning evil indirectly willed, or rather permitted to result, while good results are directly willed or intended. If the Doctor is satisfied that a dose of morphine or an application of cocaine will do more good than harm, he can, of course, prescribe or apply it. Still in such matters he must remember that the good effect is but temporary, while its pernicious consequences, especially when habits are thus contracted, are likely to be permanent and cumulative. Besides, the good results affect the body only, the evil often affect body and soul. Many a wreck in health and morals has been caused by imprudent recourse to dangerous treatment, where a little more patience and wisdom would have been equally efficient in curing the bodily ailment, without any deleterious consequences. If once a patient becomes a slave to the morphine or cocaine habit, the only cure is to cut off all the supply of the drug either at once or, at any rate, by daily diminution. To leave him free control of the poison is to co-operate in his self-destruction.
