Quality of Life and Experienced Distress of Patients Suspected of having a Rare (Chronic) Health Condition - Initial Findings from the ZSE-DUO Study

Abstract

Patients suspected of having a rare (chronic) health condition have often gone a long way within the healthcare system. To date, little is known about the health-related quality of life of this group of patients. The study aims to describe the health-related quality of life and the perceived distress of patients suspected of having a rare (chronic) health condition and compare the results with standard values of the German population. Eighty patients suspected of having a rare (chronic) health condition were recruited in the nationwide intervention study "ZSE-DUO" and reported their health-related quality of life and perceived distress using the SF-8 and the Distress-Thermometer. The patients rated all eight dimensions of quality of life as well as the physical and mental component scores of the SF-8 significantly lower than the general population. On average, the perceived distress was rated significantly higher. More than 90% of the sample indicated distress in the clinical range. Exhaustion, pain, limited mobility as well as worries and fears were mentioned most frequently as concrete problems, with percentages ranging from 73% to 90% of the total sample. In comparison to German reference data, patients suspected of having a rare (chronic) health condition report a massive impairment of their quality of life and a high burden, which is especially characterized by physical and emotional problems. The lack of a diagnosis could explain the high proportion of emotional problems, as it can create a form of legitimation of one's own disease experience. The present results underline the need for research on the psychosocial impact of the possible presence of a rare (chronic) health condition. The high distress and the impact on the physical and psychological quality of life domains also highlight the need for care in this patient group.
