Qualitative data
fatigue
Field notes were documented for all patients in the intervention group by the researcher. The field notes were coded and afterwards categorized into condition, contact, situation and life, expression of emotion, positive aspects, and symptoms. In the category condition, the code “deep breath” was coded most frequently. Frequent topics for contact were “participation”, “reception”, and “thank you/expression of gratitude”. “Reported memories” were predominant in situation and life. Expressions of emotion were very versatile, but signs of emotion were frequently coded. The category positive aspects included the highest number of codes including “smile”, “laugh”, “I like/that was great”, “joke”, and “applause”. Symptom codes were related to fatigue and exhaustion.
