Abstract Introduction Facilitating access to one-to-one peer support is an important criterion in providing aftercare for individuals with a burn injury. Although there is an increase in understanding of the perceived benefits of peer support, there are not many studies examining peer support as an intervention to promote community re-entry. This comparative study aims to examine if there is a difference in physical and mental health outcomes, including social reintegration between a group that received one-to-one peer support (PS) and a group that did not receive the peer support (NPS). Methods Subjects include adults (>=18y) with a major burn injury who received treatment at a major burn center and consented to participate in a longitudinal national database at discharge from hospital, 6-, 12-, and 24-months post injury. The physical and mental health outcomes were measured using the SF-12 Health Questionnaire – Physical (PCS) and Mental (MCS) component (50 is the average score or norm); the Satisfaction with Life Scale, and Social Integration (SI) was measured by the Community Integration Questionnaire Social Component Scale (score range 0–12; 0 is no community integration and 12 is excellent community integration). The PS program offered at the burn center is a standardized program that includes an 8-hour peer volunteer training. Independent Samples t Tests were conducted to see if there were significant differences in health outcomes between the group that received PS and the group that did not receive PS (NPS). Results Over a period of 5 years, 228 subjects consented to participate in the database. Subjects were predominantly male (70%) and White (72%), with a mean age of 44 years and the mean total body surface area was 24.8%. Sixty-three (28%) subjects received peer visits during their stay in the hospital. Compared to the NPS group, the social integration score for the PS group was higher at all time points, although it was statistically significant only at 24 months (PS= 8.22, NPS=7.13, p< .01). The PS group scored significantly higher in satisfaction with life at 6 months (p< .01) and at 12 months (p< .05). There were significant differences found in TBSA %burn (PS = 31%, NPS = 22%; p< .001), average length of acute hospital stay (PS= 52 days, NPS = 31 days; p< .01), and average length of in-patient rehabilitation stay (PS= 12 days, NPS = 5 days; p< .05). Conclusions The social integration and satisfaction with life scores of the PS group was higher when compared to those of the NPS group. The study highlights the profile of patients who seek peer support visits and has implications for delivery and utilization of burn aftercare programs. Applicability of Research to Practice The study findings highlight the emerging need for providing burn survivors with resources such as peer support to facilitate successful community reentry, and examine the effects of such interventions on health outcomes.
