ABSTRACT: Despite the literature exploring the impact of veterans’ unanticipated medical retirement on transition to civilian life, there was a lack of systematic review of this literature among veterans. The present systematic review of literature examined the impact of veterans’ UMR on transition to civilian life. Based on the implementation of a search strategy developed on the basis of six criteria for inclusion in alignment with the research phenomenon, the researcher selected 15 studies for the systematic review. Synthesis of the included studies reveled three major themes on the impact of veterans’ UMR on transition to civilian life, namely transition challenges (with two sub-themes of female veterans and identity), employment experience, and sources of support. The findings of the review expand the current body of literature in the field of veterans’ rehabilitation through a synthesis of the findings from recent literature. Additionally, implications for practice were provided, including included the need to address the discrimination experienced by veterans during their search for work after UMR and the alienation experienced by female veterans due to sexual trauma. Recommendations for future researchers included narrowing the scope of systematic reviews on the transition experiences of veterans after UMR to enable meta-analysis and conducting a systematic review on the transition experiences of only female veterans following UMR to highlight further their unique requirements.
