White River Junction Veterans Affairs Medical Center

The study is of high importance to Veterans' health because it will study a suicide prevention intervention in a Veteran population that is at high risk of suicide but has not been a specific focus of the Veteran Affairs' (VA's) suicide prevention efforts. Specifically, a growing number of Veterans are now receiving acute mental health treatment in VA-purchased settings (commonly referred to as Community Care). While these Veterans are at high risk of suicide after discharge, very little is known about how to prevent suicide in these Veterans. This study will directly address this problem by looking at whether a promising suicide prevention strategy called the VA Brief Intervention and Contact Program (VA BIC) can decrease the risk of suicide in Veterans after they are discharged from a non-VA mental health treatment setting. The proposed research is highly pertinent to the VA's top clinical priority-to prevent suicide in Veterans.

Cognitive processing therapy (CPT) and prolonged exposure therapy (PE) were widely disseminated as recommended posttraumatic stress disorder (PTSD) treatments. However, post-9/11 Veterans with PTSD rarely initiate CPT or PE, especially as an initial treatment. Little research has explored the combinations and sequences of psychosocial and medication treatments that Veterans receive ("treatment sequences"). One common and understudied treatment sequence begins with stabilization treatment, which is designed to prepare Veterans for CPT or PE. There is a significant research gap in understanding how treatment sequence affects initiation of CPT or PE. The proposed research is an innovative, mixed-methods approach to assessing the impact of variability in treatment sequence, including stabilization treatment, on initiation of CPT or PE and applying this knowledge by developing a health services intervention that facilitates timely transition to CPT or PE. Research aims can improve PTSD treatment by increasing initiation of and reducing disparities in CPT/PE.

The study will compare the use of cold snare piecemeal resection (CSPR) vs cold endoscopic mucosal resection (Cold EMR). The study will include two cohorts: one cohort for conventional adenomas 10-19mm in size and one cohort for serrated lesions 10mm or larger.
