Confidentiality is one of the core professional duties in healthcare. Patients must be able to trust that their personal information will not be disclosed without authorization. This trust is an essential prerequisite for them to speak openly about complaints, pre-existing conditions, life circumstances, or other sensitive topics. Confidentiality is therefore not merely a formality but an elemental component of professional care.

It concerns not only doctors. Employees in nursing, emergency services, and doctor's offices must also protect confidential information. The same applies to individuals who gain access to patient secrets as part of their professional activities or training. This can include, for example, medical assistants, trainees, interns, and employees in administration and billing.

What is protected by confidentiality?

In principle, all secrets entrusted to a person in connection with their professional activity or otherwise becoming known to them are protected. This includes, in particular, diagnoses, examination results, treatment measures, medications, and information on care dependency. However, the protection is not limited to medical information.

Personal, family, economic, or social circumstances may also be subject to confidentiality. Even the fact that a person is in a doctor's office, a hospital, a care facility, or receiving emergency medical treatment can already be confidential. Confidentiality applies regardless of whether the information became known verbally, in writing, digitally, or through personal observation.

The criminal law basis is primarily § 203 of the German Criminal Code. This provision protects so-called private secrets from unauthorized disclosure and covers not only certain professional secret keepers but also professional assistants and persons preparing for such a profession. Unauthorized disclosure can be punished with a fine or imprisonment.

Confidentiality and data protection are not the same

In professional life, confidentiality and data protection are often equated. Both regulatory areas protect confidential information but have different legal starting points.

Confidentiality obliges the person concerned not to disclose a secret that has become known to them without authorization. Data protection law, on the other hand, comprehensively regulates the conditions under which personal data may be collected, stored, used, transmitted, or deleted.

According to the General Data Protection Regulation, health data belongs to the particularly protected categories of personal data. Its processing is generally prohibited unless an explicit legal exception applies. Processing may be permissible, for example, if it is necessary for medical diagnosis, care, treatment, or the administration of health services and the prescribed protection requirements are met. Supplementary provisions are contained, among others, in § 22 BDSG.

Therefore, data processing may be permissible under data protection law, while it must also be checked whether confidentiality permits disclosure. Both legal areas must be observed independently.

When may information be disclosed?

Disclosure is particularly permissible if the affected person has given effective consent. Consent must be voluntary and sufficiently specific. It must be clear what information may be transmitted for what purpose and to whom. Blanket or merely presumed consent is not always sufficient.

Even within a treatment team, information may not be exchanged without limits. Disclosure is regularly considered if it is necessary for the specific treatment, care, deployment, or follow-up care. The principle of necessity is crucial: not every employee may access all existing patient data. The mere technical possibility of access does not constitute authorization.

In addition, statutory disclosure authorizations or reporting obligations may exist. This applies, for example, to certain social law transmissions or legally regulated reporting obligations. In individual cases, disclosure may also be justified to avert an imminent, considerable danger. However, such exceptions must not be assumed hastily. The specific dangerous situation, the legal interests affected, and the extent of the necessary information disclosure must always be examined.

Relatives do not have an automatic right to information

A common misconception is that spouses, children, or other close relatives automatically have the right to information about the state of health. However, the family relationship alone does not lift the duty of confidentiality.

Before providing information by phone or in person, it must be clarified whether the patient has consented or if another viable legal basis exists. In addition, the identity of the inquiring person must be reliably verified. Even a power of attorney for health care or legal guardianship does not necessarily lead to an unrestricted right to information. The specific scope of duties, the necessity of the information, and the will of the person concerned are decisive.

Typical mistakes in professional life

Violations often arise not from deliberate misconduct but from carelessness. Conversations about patients in hallways, elevators, common rooms, or other publicly accessible areas can already be problematic. The same applies to openly viewable documentation, unlocked screens, or patient lists visible to unauthorized persons.

Particularly risky are the transmission of patient data via private messengers, photographing injuries with private mobile phones, or statements in social networks. Even without naming names, a person can be identifiable based on the location of the incident, age, illness, or other accompanying circumstances.

Therefore, employees should ask themselves before each disclosure:

Am I authorized to disclose, does the recipient actually need this information, and is a secure communication channel being used?

Conclusion

Confidentiality accompanies the entire care process – from the doctor's office to emergency services and inpatient or outpatient care. It protects not only individual data but also the personal trust of patients in the healthcare system.

Acting in compliance with the law requires disclosing information only on a sound basis, to the necessary extent, and to authorized recipients. Especially everyday situations such as inquiries from relatives, handovers, digital communication, or conversations with colleagues therefore demand a strong awareness of confidentiality. Institutions must support this awareness through clear processes, suitable technical protective measures, and regular training.
