“…Six DAs aimed to support patients in making a treatment decision [38][39][40][41][42][43], two studies focused on decisions to participate in cancer screening programs [44,45], five on decisions concerning cardiopulmonary resuscitation (CPR) and intubation [46][47][48][49][50], one on prevention of falls [51], and one on both diagnosis and treatment of gastrointestinal cancer [52]. Eight studies compared the DA with usual care [38,39,42,43,[47][48][49], and eight compared the DA to an alternative intervention, such as educational pamphlets or verbal education [40,41,[44][45][46][50][51][52]. Most studies included participants from the age of 65 or older [40,41,46,[49][50][51], 70 or older [38,43,44], or 75 or older [45,47].…”
