Background Many patients who are discharged from the hospital without receiving a clear-cut diagnosis of their chest pain continue to consume health care because of disabling physical and psychological symptoms. By identifying their experiences and concerns following hospitalization, an empirical basis for discussions on ways of improving the care of these particular patients will be obtained. Methods A qualitative analysis of semi-structured interviews with 38 patients with a diagnosis of unspecified chest pain was carried out. Results Two-thirds of the respondents had unanswered questions and concerns that had not been addressed. They found it difficult to understand why they had not undergone more tests. They requested an explanation for their chest pain, at the very least, or were worried about the future. Some respondents accepted the fact that they had not been given a sufficient amount of time and information. They referred to the stressful working situation of the physicians, the view that their admission could be regarded as unnecessary or that physicians at the hospital could not be expected to do more than exclude serious diseases. Conclusions Health professionals should address their patients' questions and fears properly and provide them with the most probable explanation for their symptoms. When taking the harmlessness of their symptoms or the situation of their caregivers into account, patients may find it inappropriate to impose further demands on care.
