Sattoe et al. BMC Nephrology 2013, 14:279http://www.biomedcentral.com/1471-2369/14/279 Effective peer-to-peer support for young peoplewith end-stage renal disease: a mixed methodsevaluation of Camp COOL Jane NT Sattoe1,2*, Susan Jedeloo1 and AnneLoes van Staa1,2 Background: The Camp COOL programme aims to help young Dutch people with end-stage renal disease (ESRD)develop self-management skills. Fellow patients already treated in adult care (hereafter referred to as ‘buddies')organise the day-to-day program, run the camp, counsel the attendees, and also participate in the activities. Theattendees are young people who still have to transfer to adult care. This study aimed to explore the effects of thisspecific form of peer-to-peer support on the self-management of young people (16–25 years) with ESRD whoparticipated in Camp COOL (CC) (hereafter referred to as ‘participants').
Methods: A mixed methods research design was employed. Semi-structured interviews (n = 19) with initiators/staff,participants, and healthcare professionals were conducted. These were combined with retrospective and pre-postsurveys among participants (n = 62), and observations during two camp weeks.
Results: Self-reported effects of participants were: increased self-confidence, more disease-related knowledge, feelingcapable of being more responsible and open towards others, and daring to stand up for yourself. According toparticipants, being a buddy or having one positively affected them. Self-efficacy of attendees and independenceof buddies increased, while attendees' sense of social inclusion decreased (measured as domains of health-relatedquality of life). The buddy role was a pro-active combination of being supervisor, advisor, and leader.
Conclusions: Camp COOL allowed young people to support each other in adjusting to everyday life with ESRD.
Participating in the camp positively influenced self-management in this group. Peer-to-peer support through buddieswas much appreciated. Support from young adults was not only beneficial for adolescent attendees, but also for youngadult buddies. Paediatric nephrologists are encouraged to refer patients to CC and to facilitate such initiatives. Togetherwith nephrologists in adult care, they could take on a role in selecting buddies.

Phase 3 refers to full autonomy in participation. Because we were interested in successful transition to adulthood, the phases were dichotomised as follows: 0 = phases 0–2, 1 = phase 3.
