“…The first 30 years of knowledge on TS from a medical patient-centered care perspective (Dote et al, 1991) show that today's best TS practice is based on consensus and position statement papers (Ghadri et al, 2018a(Ghadri et al, , 2018bLyon et al, 2016), but guidelines have yet to be developed. At the same time, the best practice from a nursing personcentered perspective (Ekman et al, 2011;Santana et al, 2018), including the person's own statements of reasons, feelings, and needs (Curragh et al, 2020) in order to establish a partnership followed by shared decision making and understanding (Morgan & Yoder, 2012), is only based on five empirical Scandinavian TS studies with an explorative approach (Dahlviken et al, 2015;Mäenpää et al, 2020;Sundelin et al, 2020;Wallström et al, 2016aWallström et al, , 2016b. A case study that includes a personcentered and holistic approach to a person's life is another way of exploring close, in-depth, and detailed patient-reported outcomes and knowledge in a defined context to generate and illustrate theories and models that describe how different aspects of a person's life interact (Ebneyamini & Sadeghi Moghadam, 2018;Stjelja, 2013;Yin, 2009).…”
