Moya Moya Disease

Moyamoya disease is characterized by idiopathic, progressive and chronic occlusion of the main arteries that perfuse the brain. In response to ischemia, abnormal “moyamoya vessels” (Japanese word which stands for puffs of smoke) and meningeal collaterals form. Children are treated initially with revascularization procedures to improve the perfusion to the brain. Under the leadership of Dr Steinberg and Dr Dutta, Dr Bruzoni trained in harvesting the greater omentum using minimally invasive techniques and use it as a graft that help revascularize the brain in complex patients with Moya Moya disease that have failed primary vascular reconstruction. As far as we know, our team is the only group in the country that performs this operation in a minimally invasive way. Patients come all over the country and the world to undergo this procedure and we continue to innovate the technique to improve the outcome of our patients.


Patient Centered-Language Concordant Care

The language barriers Hispanics and all ethnic minorities face are well documented in the medical literature and have been found to adversely impact not only their access to medical care, but also the quality of medical care received. About 40% of the patients in our pediatric surgery service are Hispanic, and most of them do not speak English appropriately. In an effort to improve the healthcare we deliver to limited English proficient (LEP) patients, Dr. Bruzoni developed the Di-vision’s first Hispanic Clinic. All aspects of the patient’s visit to the Hispanic clinic are adminis-tered in Spanish, from registration to postoperative teaching. Dr. Bruzoni has conducted his re-search in two phases so far with patient satisfaction with and without an interpreter in the first phase. This study found that language concordant care indeed improves patient satisfaction and understanding for Hispanic families when compared to language discordant care. He continued this research in phase two by evaluating the flow of information during clinic visits and this second study showed that language concordant care improves question asking behavior and access to in-formation among Spanish-LEP patients in a pediatric surgery setting. He plans to continue with a third phase by reaching out to other clinics in the hospital in the hopes they adopt a similar version of our Hispanic Clinic.

Background: Hispanics account for over 60% of the U.S. population growth and 25% speak little-to-no English. This language barrier adversely affects both access to and quality of care. Surgical specialties trail other medical fields in assessing the effects of language barriers to surgical clinical care and patient satisfaction. This study was designed to assess the effects of patient-provider language concordance on a pediatric surgery practice.

Methods: A surgery-specific, 7-point Likert scale questionnaire was designed with 14 questions modeled after validated patient satisfaction surveys from the literature. Questions concerning provider-patient language concordance, quality of understanding, and general satisfaction were included. Surveys were administered to families of patients in the General Pediatric Surgery Clinic at our institution. Families were categorized into three groups: English-speaking, regardless of race/ethnicity; Spanish-speaking using interpreter services with an English-speaking medical team; and Spanish-speaking communicating directly with a Spanish-speaking medical team (Hispanic Center for Pediatric Surgery, HCPS). One-way analysis of variance was used to test for group differences.


Inflammatory Bowel Disease

Dr Bruzoni directs the surgical aspect of our inflammatory bowel disease program (Crohn’s disease and Ulcerative colitis). We have a strong collaboration with our GI team and our multidisciplinary approach results in patient centered care, coordinated procedures, early patient and family education in potential surgical interventions, and combined research efforts. One of our current projects involves the P-APPY Trial which will study prophylactic appendectomy in pediatric patients with refractory ulcerative colitis in order to decrease the rate of proctocolectomy in the future.
