The privileged information has been said to include knowledge acquired through the statements of others surrounding the patient.[361] But it would seem that the fact that a third person was present during a physician’s visit may be shown by the physician, as well as what passed between the patient and the third person, if it was such information as a layman would have gathered.[362] The information from the third person regarding the patient is protected even though the patient be absent;[363] but not if the third person does not employ the physician, and the information thus acquired is not necessary to enable the physician to act in a professional capacity.[364] It is suggested in one case, but not determined, that it would be improper for a physician to state the value of the services of a nurse in attendance upon his patient, as that would involve a consideration of the condition of his patient;[365] but it has been held that a physician can testify to the fact of a nurse’s services.[366] But it is information regarding the patient that is privileged, and therefore a physician may disclose what his patient told him about another, even though the subject of inquiry be the attitude of the patient toward the other;[367] and likewise the physician may disclose what he told his patient about a third person;[368] so also the physician may testify as to family events in no way connected with physical complaints.[369] It has been held, too, that admissions made by a patient to his physician, tending to show contributory negligence on the part of the patient, at a time when the communication could not well have been made to enable the physician to prescribe, namely, on the physician’s third and last visit, may be proven by the physician.[370] The physician may properly testify that he did attend as physician,[371] and that the patient was sick, and he can state when and how often he attended him,[372] and whether his knowledge was acquired while in professional attendance,[373] but it is open to the Court to determine from the evidence whether it was so acquired.[374] “_Matter Committed._”—In Indiana the protection covers _matter committed_. It would seem that the use of the word _committed_ implies confidence and that the protected matter is only confidential communications; but an earlier statute in that State applied to “matters confided,” and it was held to cover matters learned by observation or examination, or by communication from the patient, whether learned under an injunction of secrecy, express or implied, or not;[375] and it has been held that the present law forbids the disclosure of matters learned in a sick-room, no matter how the knowledge may have been acquired.[376]
