Preliminary Effectiveness of an In-Hospital Peer Support Program, Adolescent and Young Adult Hiroba, on Anxiety in Adolescent and Young Adult Patients with Cancer.

Purpose: Adolescent and young adult (AYA) patients with cancer have few opportunities to connect with patients of the same generation while hospitalized. Although anxiety is frequently reported by them, there are no reports on the psychological effectiveness of an in-hospital patient support program based on peer support. This study aimed to evaluate the effectiveness of a program, termed Adolescent and Young Adult Hiroba (AYA Hiroba), for anxiety in AYA patients with cancer. Methods: This single-center, prospective, observational study in 24 AYA patients with cancer was conducted at the National Cancer Center Hospital in Japan. The Hospital Anxiety and Depression Scale-Anxiety (HADS-A) was used to evaluate the primary outcome, anxiety. The Distress Thermometer (DT) was used to evaluate the secondary outcome, distress. The two outcomes were assessed before and after participation in AYA Hiroba. The Net Promoter Score (NPS) was used to evaluate satisfaction after participation in AYA Hiroba. Participants' free-text descriptions of the program were categorized according to similarities and differences. Results: The HADS-A and DT scores were significantly lower after the program than before ( p  < 0.001), as was the percentage of AYA patients with cancer with high distress ( p  = 0.04). The NPS was 27, which was lower than the value of 52 obtained in our previous study. Requests and suggestions to improve the program were grouped into three categories: content, facilitation, and online connection environment. Conclusion: This study suggests the preliminary effectiveness of the in-hospital peer support program for anxiety in AYA patients with cancer. The Clinical Trial Registration number: UMIN000045779.
