Privacy, as used in this discussion, is the interest that persons have in maintaining control of information about them; medical privacy refers specifically to information concerning persons’ medical conditions. Confidentiality, a term that often is used interchangeably with privacy, refers more narrowly to the obligation to maintain privacy assumed by someone who enters into a relationship marked by the promise that information that is disclosed will not be revealed to others.
Ethical Underpinnings
What accounts for the long-standing tradition in medicine of protecting patients’ privacy? Medical ethicists point to two deep-seated ethical rationales. The justification most commonly offered is a consequentialist or utilitarian one: if patients are to provide the information required for physicians to diagnose and treat them effectively, they must trust that their physicians will not disclose those data to third parties
(11). In the absence of some guarantee of privacy, patients will either avoid coming for care, or if they do come, will withhold information necessary for treatment. This rationale seems particularly potent in psychiatry, where the information elicited from patients includes symptoms, behaviors, thoughts, and affects that might cause embarrassment, stigma, and discrimination were they to become generally known.
Consequentialist justifications can be susceptible, at least in principle, to empirical testing. Surveys of patients and of the population at large have confirmed that most people value highly the privacy of their medical information. For example, a recent Gallup survey conducted for the Institute for Health Freedom found that 78% of respondents felt that the confidentiality of their medical records was very important
(12). As a corollary, there was strong opposition to giving nonmedical groups access to medical records. Thus, 95% of respondents opposed banks’ having access to their records; 92% felt similarly about government agencies; 84% opposed access by the police, lawyers, or employers; and 82% opposed insurance companies’ seeing their records without their consent. Studies of psychiatric
(13,
14) and other mental health patients
(15,
16) have revealed similar attitudes.
In keeping with utilitarian theory, those advocating a consequentialist basis for privacy must show that, in its absence, medical care would not be provided as effectively, i.e., that patients would withhold information from their caregivers or decline to come for treatment altogether. Although this argument seems self-evident to many privacy advocates, few attempts have been made to support this reasoning empirically, and the results have been mixed. A survey sponsored by the California Health Foundation revealed that 15% of a national sample reported doing something out of the ordinary to protect their medical privacy, including not seeking care and giving inaccurate or incomplete information
(17). Probably the strongest data exist for adolescents, 25% of whom in one study said they would forego care if they thought their parents might find out
(18). Another study of 2,224 high school students showed that those who perceived that their communications with physicians were confidential were more likely to have had pelvic exams and to have discussed sexual behavior and substance abuse with their doctors
(19). On the other hand, 8% of respondents in that study reported that they actually had foregone care because of a fear that their parents would learn about their treatment.
Studies of mental health treatment have yielded mixed results, but often because the methods used were less than optimal. Some studies utilizing nonclinical samples (e.g., university students) found that varying the level of assurance of confidentiality did not affect the amount of information disclosed in an interview
(20,
21), although other studies reached contrary conclusions
(22). The relevance of these studies to real-life settings, however, is questionable. In the only two studies of this sort to examine patients currently receiving mental health treatment, when a variety of limitations on confidentiality were described, willingness to disclose and actual disclosure of information were reduced
(23,
24). Overall then, although there are data suggesting that patients in mental health settings are similar to those in general health settings in the extent to which their disclosures may be negatively impacted by a lack of privacy, the number of studies is small and the data are not robust. Nonetheless, belief remains strong in the field that potential adverse effects on treatment constitute the strongest rationale for protection of patients’ privacy.
Some students of medical privacy, however, impelled in part by the relative paucity of data supporting consequentialist justifications—especially in psychiatric treatment—have suggested that a second ethical argument be considered. They argue that medical privacy can better be justified by using what ethicists refer to as a deontologic approach, i.e., considering privacy as a good in itself, rather than seeing its value only in the positive effect it may have on patients’ health
(25,
26). Most often, the role of privacy in advancing individual autonomy is identified as the basis for this claim. One commentator speaks of the “insulation that privacy provides so that as self-conscious beings we can maintain our self-respect, develop our self-esteem, and increase our ability to form a coherent identity and set of values, as well as our ability to form varied and complex relationships with others”
(27, p. 213).
Although a deontologic argument for medical privacy can be applied to medical care in general, it probably works best for psychotherapy per se. The ability to speak freely with another person about one’s innermost thoughts, fears, and passions is clearly dependent on the belief that one’s revelations will go no farther. Creating a space within which this sort of dialogue can occur is likely to facilitate the conscious exploration of alternative modes of thought and behavior on which truly autonomous functioning rests. A society like ours, built on the premise that individual autonomy ought to be encouraged, should be receptive to the claim that protecting the privacy of the psychotherapeutic relationship carries positive social value. Indeed, insofar as psychiatrists deal largely with conditions that often impair autonomous function, the same argument might be advanced for psychiatric treatment in general.
The practical import of these ethical arguments is the widespread acceptance among members of the medical profession of the principle that physicians owe patients a duty of confidentiality, unless patients release them from it by offering consent for the disclosure of information. Embodied in the American Medical Association’s
Principles of Medical Ethics is the admonition that “[a] physician…shall safeguard patient confidences within the constraints of the law”
(28, p. 2). The American College of Physicians, representing the nation’s internists, is still more explicit: “To protect patient confidentiality, information should only be released with the written permission of the patient or the patient’s legally authorized representative”
(29). Similarly, the American Psychiatric Association’s
Annotations to the AMA’s
Principles holds that “[a] psychiatrist may release confidential information only with the authorization of the patient or under proper legal compulsion”
(28, p. 6). The medical profession’s ethical commitment to protecting privacy seems clear. However, since the boundaries of the profession’s ethical duties appear to be circumscribed by the law, the parameters of legal protection for medical information assume particular significance.
Legal Underpinnings
Legal protection of medical privacy is a much more recent and fragmentary phenomenon than many people suppose. The law’s first foray in this area was aimed at preventing the courts from compelling disclosure of information that physicians obtained in their attendance on patients. Abandoning the common law rule that the courts had the right to every person’s testimony, New York in 1828 passed the nation’s first statute establishing a physician-patient testimonial privilege. Under the privilege, patients had the right to prevent their physicians from testifying in regard to any information patients may have communicated in the course of treatment. In the century that followed, many states emulated New York, passing privilege statutes of their own
(30). However, the courts were often hostile to medical privileges, since they were seen—not unreasonably—as complicating the adjudicatory process. Given that these privileges were usually defended on consequentialist grounds—i.e., as necessary to encourage patients to seek medical care—they were also susceptible to attack on the basis that patients with significant illnesses would pursue treatment regardless of whether a privilege existed, because patients typically did not need to communicate sensitive information to obtain medical care. By the mid-20th century, physician-patient privileges began to fall from favor, although they still exist in many jurisdictions.
As enthusiasm for physician-patient privileges declined in the second half of the 20th century, there was a concomitant rise in the number of states creating privileges designed specifically to cover mental health treatment, often denominated psychotherapist-patient privileges. Today, every jurisdiction in the United States offers some sort of privilege for treatment by mental health professionals, by no means limited to psychotherapy
(31). Often riddled with exceptions (which may include, for example, testimony related to criminal offenses, child custody, and child abuse and testimony in cases in which patients have based a legal claim on some aspect of their mental state), these statutes nonetheless provide some real protection for patients. In 1996, the U.S. Supreme Court, exercising the discretion afforded it in the Federal Rules of Evidence, gave judicial recognition to a psychotherapist-patient privilege for the federal courts
(31). The Court’s decision in
Jaffee v. Redmond offered strong support for privacy in psychotherapeutic treatment: “The psychotherapist privilege serves the public interest by facilitating the provision of appropriate treatment for individuals suffering the effects of a mental or emotional problem. The mental health of our citizenry, no less than its physical health, is a public good of transcendent importance”
(31). Although the precise dimensions of the federal privilege will be determined by subsequent cases, it is worth emphasizing that it is likely to cover mental health treatment in general, rather than being limited to psychotherapy per se
(32).
Parallel to the growth of privileges for treatment by mental health professionals has been the development of state statutes regulating the circumstances under which medical information can be disclosed to others besides the courts. These statutes create a patchwork of regulation, often focused on particular disorders, such as AIDS, or on diagnostic information, such as genetic testing
(33). Forty-five states and the District of Columbia have statutes specifically addressing release of mental health information
(34). Although their provisions vary greatly, many statutes address the criteria for a valid consent to release of information, specify when information can be disclosed to other health professionals and to family members who may be involved in patients’ care, and enumerate the circumstances under which access to data is allowed for other purposes, including research, public health needs, and quality improvement efforts
(34).
While state legislatures were limiting the circumstances in which medical information can be disclosed without patients’ consent, state courts were recognizing causes of action under which patients who were harmed by unauthorized disclosures could obtain appropriate compensation. A typical case, echoing decisions in other jurisdictions (e.g., references
35–37), is
Alberts v. Devine, a 1985 decision of the Massachusetts Supreme Judicial Court
(38). Alberts, a minister who had sought psychiatric treatment from Devine, lost his pulpit when the psychiatrist acquiesced in the request of Alberts’s superiors and revealed the nature of his condition to them. The court held that patients have “a valid interest in preserving the confidentiality of medical facts communicated to a physician or discovered by the physician through examination.” Hence, “a violation of that duty [of confidentiality], resulting in damages, gives rise to a cause of action sounding in tort against the physician”
(35). Not only was Devine liable to compensate Alberts for the harm he suffered, but Alberts’s superiors, who had induced Devine to violate his duty, were held liable as well. Like the other courts that have ruled in this area, the Massachusetts court recognized exceptions to the requirement of confidentiality when a danger existed to third parties or when disclosure was otherwise required by law.
To this point, the focus has been largely on state law and regulation, since until recently the federal government left regulation of medical privacy largely to the states. One important exception is embodied in the Public Health Service Act, which establishes special protections for the records of patients who receive treatment for alcohol or drug abuse in federally supported, specialty treatment programs
(39). The resulting regulations strictly limit disclosure without the patient’s consent to situations in which an emergency exists, a crime has been committed at the program, information has been obtained relating to child abuse, a court—applying a set of criteria that includes balancing the benefits and harms of disclosure—orders release, and a small number of other circumstances
(40).
In sum, the impact of law on medical privacy by and large has been complementary to the thrust of the medical profession’s ethical codes. Although there are a number of discrete exceptions, often involving a risk of harm to third parties (e.g., child abuse) or the superordinate needs of the courts, physicians have been obliged to respect patients’ medical privacy. Patient consent has been the sine qua non required for disclosure of information, and physicians can be subject to civil actions, licensure proceedings, and, sometimes, criminal penalties for violation of that rule.
