Comparative effectiveness of surveillance colonoscopy intervals on colorectal cancer outcomes in a national cohort of patients with inflammatory bowel disease.
The purpose of this study was to determine the comparative effectiveness of varying colonoscopy intervals on colorectal cancer (CRC) outcomes among patients with inflammatory bowel disease (IBD). Data was from the National Veterans Health Administration. Findings showed that, in a national cohort of patients with CRC-IBD, colonoscopy within 3 years prior to CRC diagnosis was associated with early tumor stage at diagnosis, and colonoscopy within 1 year was associated with a reduced all-cause mortality compared with no colonoscopy, supporting colonoscopy intervals of 1 to 3 years in patients with IBD in order to reduce late-stage CRC and all-cause mortality.

Pharmacodynamic assessment of vedolizumab for the treatment of ulcerative colitis.
This review discusses the chemistry, pharmacologic properties, clinical efficacy, and safety of vedolizumab in ulcerative colitis. It concluded that vedolizumab is a promising new agent for the treatment of ulcerative colitis. Its mechanism of action differs from tumor necrosis factor (TNF)-alpha inhibitors and immune suppressants, allowing it to be used in cases of TNF-alpha inhibitor failure or non-response, or as a first-line biologic drug.

Alvimopan use, outcomes, and costs: a report from the Surgical Care and Outcomes Assessment Program Comparative Effectiveness Research Translation Network Collaborative.
The researchers investigated the effectiveness of alvimopan in routine clinical practice and its impact on hospital costs. They found that when used in routine clinical practice, alvimopan was associated with a shorter length of stay and limited but significant hospital cost savings. They concluded that both efficacy and effectiveness data support the use of alvimopan in routine clinical practice, and its use could be measured as a marker of higher quality care.

Prospective comparative effectiveness trial for malignant bowel obstruction: SWOG S1316.
This paper is an update on the status of the Prospective Comparative Effectiveness Trial for Malignant Bowel Obstruction trial (S1316), the aim of which is to assess the quality of life outcome of “good days” for patients with malignant bowel obstruction (MBO) who receive surgical intervention in comparison with patients who undergo nonsurgical intervention.

Mortality associated with medical therapy versus elective colectomy in ulcerative colitis: a cohort study.
This study sought to determine whether patients with advanced ulcerative colitis (UC) treated with elective colectomy have improved survival compared with those treated with medical therapy. It found that elective colectomy was associated with improved survival compared with long-term medical therapy, although this result did not remain statistically significant in all sensitivity analyses.

TELEmedicine for Patients with Inflammatory Bowel Disease (TELE-IBD): design and implementation of randomized clinical trial.
This study compares disease activity and quality of life over 1 year in a randomized trial of IBD patients receiving standard care versus telemedicine. If effective, telemedicine should decrease symptoms, improve quality of life, and decrease health care utilization. The burden associated with use of telemedicine for patients and providers needs to be assessed. This trial is ongoing and will be completed in July 2016.

Comparative effectiveness of immunosuppressants and biologics for inducing and maintaining remission in Crohn's disease: a network meta-analysis.
The authors compared therapies for induction and maintenance of remission in patients with Crohn's disease. They found that adalimumab and infliximab + azathioprine are the most effective therapies for induction and maintenance of remission of Crohn's disease.
