The doctor–patient relationship is central to the practice of healthcare and is essential for the delivery of high-quality health care in the diagnosis and treatment of disease. The doctor–patient relationship forms one of the foundations of contemporary medical ethics. Most universities teach students from the beginning, even before they set foot in hospitals, to maintain a professional rapport with patients, uphold patients' dignity, and respect their privacy.
A patient must have confidence in the competence of their physician and must feel that they can confide in him or her. For most physicians, the establishment of good rapport with a patient is important. Some medical specialties, such as psychiatry and family medicine, emphasize the physician–patient relationship more than others, such as pathology or radiology.
The quality of the patient–physician relationship is important to both parties. The relationship is one that is built in terms of mutual respect, knowledge, trust. Additionally, the doctor and patient's values and perspectives about disease, life, and time available play a role in building up this relationship. A strong relationship between the doctor and patient will lead to frequent, quality information about the patient's disease. Enhancing the accuracy of the diagnosis and increasing the patient's knowledge about the disease all come with a good relationship. Where such a relationship is poor the physician's ability to make a full assessment is compromised and the patient is more likely to distrust the diagnosis and proposed treatment, causing decreased compliance to actually follow the medical advice. In these circumstances and also in cases where there is genuine divergence of medical opinions, a second opinion from another physician may be sought or the patient may choose to go to another physician. Additionally, the benefits of any placebo effect are also based upon the patient's subjective assessment (conscious or unconscious) of the physician's credibility.
