Tailored Transition for IBD Adolescents

Inflammatory Bowel Disease

Background: Smooth transition of adolescent patients diagnosed with inflammatory bowel diseases (IBD) to adult care is necessary in order to secure continues clinical management and to prevent possible deleterious clinical and psychosocial implications. In recent years there is an emphasis on successful transition, however, there are no standardized models or consensus guidelines incorporating both clinical and psychosocial aspects of transition. Objectives: To examine the effect a comprehensive clinical and psychosocial transition package on clinical management and patients outcomes in adolescents with IBD. Design: A prospective, trans-sectional study. Setting: The Schneider Children's Medical Center and the Rabin Medical Center. Participants: Children 17 year to 18 years who are diagnosed with IBD and are planned to initiate transition process to adult care. Main outcome measures: Change in clinical management as a result of tailored re-evaluation as a part of tailored transition package. Secondary outcome measures: a. The effect of a tailored transition package on patients' self-efficacy perception and readiness for transition. b. The effect of a tailored transition package on patient's outcomes (disease activity, flares, hospitalizations) during the first year following transition.

General intervention scheme: Patients with an established diagnosis of IBD (crohn's disease, ulcerative colitis or IBD-unclassified) will be enrolled between the age of 17 and 17.5 years. Patients are eligible for enrollment 6 months following diagnosis and onward. Following enrollment each patient will undergo a structured re-evaluation as follows: Each patient will be thoroughly examined and have height ,weight, body mass index performed as well as comprehensive laboratory examinations. Fecal sample for fecal calprotectin will be obtained as well. Extent of disease will be registered using the Montreal classification. Disease activity indices will be calculated according to the Harvey-Bradshaw Index (HBI) for crohn's and Partial Mayo Score (PMS) for UC. Serum of patients treated with biologic medications will be analyzed for drug trough levels and anti-drug antibodies. Patients treated with thiopurines will have their blood analyzed for thiopurines metabolites. Patients will complete a self-efficacy and Transition Readiness Assessment Questionnaire (TRAQ). Both questionnaires were linguistically validated by bi-directional translation. Patients diagnosed with ileal or ileo-colonic crohn's will undergo an MR Enterography (MRE). In crohn's patients, MRE was shown to have a higher impact on patient management than colonoscopy. Patients diagnosed with either UC, IBD-U or Crohn's colitis will undergo a flexible sigmoidoscopy. Flexible sigmoidoscopy was recently shown to have a high degree of correlation with complete colonoscopy in assessments of UC activity. Treating physicians are entitled to offer the patient a more extensive endoscopic evaluation (complete colonoscopy, gastroscopy) or radiologic evaluation (pelvic MRI, liver ultra-sound) if deemed necessary according to clinical indications. Following the completion of clinical, laboratory and endoscopic/imaging evaluation a re-evaluation visit with both treating pediatric gastroenterologist and receiving adult gastroenterologist will be set. During this visit physicians will discuss the current treatment plan with the patient and the need for changes in therapeutic regimens (including step-up, step-down, adding or withdrawing optional treatments). A transition visit with both treating gastroenterologists will be set 3-6 months following the re-evaluation visit (around 18 years of age) in order to assess the efficacy of the therapeutic plan and to complete the transition process. During the transition visit patients will, again, complete a self-efficacy and TRAQ questionnaires. In between the reevaluation visit and the transition visit the patients will be followed according to clinical indications by the treating pediatric gastroenterologist. Prior to the transition visit each patient and parents will perform a transition preparation meeting with a multi-disciplinary team including a pediatric IBD nurse, an adult IBD nurse and a social worker. During this meeting the team will discuss practical issues concerning transition, instruct the patient on subjects specifically related to disease implications during late adolescence and early adulthood (substance abuse, alcohol, contraceptives, pregnancy, high education, work) and address special psycho-social needs/concerns. According to the team discretion, if a need for a meeting with the institute's psychologist is necessary, such meeting will be set within 30 days. At 12 months following transition data on disease activity and outcomes including flares, hospitalizations and surgical interventions since transition will be collected. Data will be compared with an historic cohort of matched patients (case-controlled) who completed routine transition in the time period prior to the study in which transition was performed following 1-2 visits of the patient with both pediatric and adult gastroenterologists.
