[Pneumological Rehabilitation in Patients with Long Covid - Health Changes at the End of the Inpatient Rehabilitation Measure].

Background: Some people suffering from Covid-19 can be affected by persistent symptoms and long-term consequences of the disease (Long Covid) beyond their acute phase. Consequently, this can lead to restrictions in participation. Therefore, the focus is on medical rehabilitation in which Long Covid is treated as a new challenge.

Methods: A prospective, exploratory observational study will be conducted. The written survey of Long Covid rehabilitants takes place at the beginning and end of the pneumological rehabilitation. The aim of the study is to describe the rehabilitation contents and goals, the subjective burdens, the social and occupational participation as well as the health-related changes. Among other factors, disease-specific symptoms, quality of life, participation, psychological impairments, fatigue, and performance were recorded.

Results: Long Covid rehabilitants (N=221) participate in the written survey. At the end of rehabilitation, the questionnaire survey indicated significant improvements in almost all outcome parameters with a large effect (p<0.01; ES between 0.76 (anxiety) and 1.30 (fatigue)). All corona symptoms, such as breathlessness on exertion, fatigue or lack of strength improved significantly at the end of rehabilitation. Moreover, the rehabilitants most frequently name the improvement of their health (92%), the increase of their performance (92%) and the improvement of the respiratory muscle strength (78%) as rehabilitation goals. In fact, these goals are achieved by 60 to 70%, significantly fewer rehabilitation patients reach the restoration of their ability to work (32%) or a better ability to concentrate (17%). Respiratory physiotherapy, endurance training and medical training therapy are described as most helpful. At the end of rehabilitation, 76% rated their rehabilitation success as good to excellent based on a single question.

Conclusion: The first data of the study reveal that Long Covid rehabilitants are exposed to substantial burdens. Through medical rehabilitation, the patients experience medical and social support and experience significant improvements in all recorded health-related outcomes.
