Chapter 5 100 al., 2023; Ly et al., 2021). We used interactive whiteboard software Miro (RealtimeBoard, 2022) for discussion, employing colored stars to rank concepts. The group mapped these concepts into a matrix, identifying key ones for further exploration. Our final patient journey, incorporating interview and focus group inputs, identified three design opportunities (see Figure 5.2). One critical opportunity, “The Hole,” focused on the vulnerable period between hospital discharge and rehabilitation start, where patients face emotional vulnerability and lack of information. This period often leads to demotivation at the rehabilitation’s onset. Aligned with the opportunity and insights from context mapping, we identified several key needs that our intervention would need to address (see Table 5.2). In general, our intervention would require guiding patients through the waiting period, offering information to enhance understanding and encouraging small preparatory steps toward rehabilitation, thereby fostering a sense of certainty and guidance. Table 5.2 Needs of cardiac patients during their waiting period preceding CR and their corresponding descriptions. Need Description Certainty during waiting period To gain a sense of security in patients during their waiting period, ensuring they feel confident and comfortable about their current health situation. Physical activity confidence To feel less fear of medical incidents when being physically active. Rehabilitation expectancy To achieve a clear understanding of what can be expected during CR and insight into their future healthcare journey. Managing emotions To foster positive emotions, gain calmness and reduce stress levels, thereby improving emotional wellbeing Health status understanding To receive comprehensive information about the current medical situation, including what has happened and the underlying cause of the health condition. Pre-rehabilitation guidance To receive guidance on the lifestyle activities that can be done while waiting for rehabilitation to begin, ensuring an understanding of what actions are safe and beneficial to perform. 5.2.2.4 Phase two: Design We developed a range of potential solutions that resonated with the identified design opportunity and needs. We employed several design thinking techniques, including group brainstorming, brainwriting, and mind mapping (Tassoul, 2009). Subsequently, we refined a selection of the most compatible ideas into a preliminary intervention concept that was discussed and iterated upon in two co-creation sessions with both patients and health providers (D.1). In these sessions, we specifically gathered feedback about the concept and co-developed ideas on the topics: parameters to track, tone-of-voice
