Background & Aims Gastrointestinal (GI) diseases account for substantial morbidity, mortality and cost. Statistical analyses of the most recent data are necessary to guide GI research, education and clinical practice. We estimate the burden of GI disease in the US. Methods We collected information on the epidemiology of GI diseases (including cancers) and symptoms, along with data on resource utilization, quality of life, impairments to work and activity, morbidity, and mortality. These data were obtained from the National Ambulatory Medical Care Survey; National Health and Wellness Survey; Nationwide Inpatient Sample; Surveillance, Epidemiology, and End Results Program; National Vital Statistics System; Thompson Reuters MarketScan®; Medicare; Medicaid; and the Clinical Outcomes Research Initiative’s National Endoscopic Database. We estimated endoscopic use and costs and examined trends in endoscopic procedure. Results Abdominal pain was the most common gastrointestinal symptom that prompted a clinic visit (15.9 million visits). Gastroesophageal reflux was the most common GI diagnosis (8.9 million visits). Hospitalizations and mortality from Clostridium difficile infection have doubled in the last 10 years. Acute pancreatitis was the most common reason for hospitalization (274,119 discharges). Colorectal cancer accounted for more than half of all GI cancers and was the leading cause of GI-related mortality (52,394 deaths). There were 6.9 million upper, 11.5 million lower, and 228,000 biliary endoscopies performed in 2009. The total cost for outpatient gastrointestinal endoscopy examinations was $32.4 billion. Conclusions GI diseases are a source of substantial morbidity, mortality and cost in the US.

Despite the availability of highly effective therapy for hepatitis C virus (HCV) infection, few patients receive treatment. Barriers arising at multiple levels, from diagnosis to specialist referral, may impede the delivery of hepatitis C care. At the patient level, lack of awareness, fear of side effects, poor adherence, and comorbid conditions may prevent treatment. For providers, limited knowledge, lack of availability, and communication difficulties may be problematic. At the government and payer level, a lack of promotion, surveillance, and funding may interfere. Each of these barriers needs to be addressed if wider implementation of antiviral therapy is to be achieved.

SA HealthPlus, one of nine national Australian coordinated care trials, addressed chronic illness care by testing whether coordinated care would improve health outcomes at the cost of usual care. SA HealthPlus compared a generic model of coordinated care for 3,115 intervention patients with the usual care for 1,488 controls. Service coordinators and the behavioral and care-planning approach were new. The health status (SF-36) in six of eight projects improved, and those patients who had been hospitalized in the year immediately preceding the trial were the most likely to save on costs. A mid-trial review found that health benefits from coordinated care depended more on patients' self-management than the severity of their illness, a factor leading to the Flinders Model of SelfManagement Support.Keywords: Chronic disease, coordinated care, care plan, self-management, health outcomes. In Australia, the coordination of care for patients with multiple service needs may be hampered by mixed funding sources and the lack of integrated systems of care. Each of the commonwealth, state, and territory governments funds public health services: the commonwealth government administers the taxpayer-funded Medicare program to provide universal access to public health services by reimbursing general practitioners (GPs) and specialists on a fee-forservice basis, and the state governments support public hospitals. A mixture of state and commonwealth programs fund community care, including allied health services, and individuals can purchase private health insurance, which provides private hospital care and a range of ancillary services (physiotherapy, psychology, podiatry, etc.).In 1997, Australia's governments began trials of coordinated care to develop and test models of service delivery for chronic conditions (Commonwealth Department of Human Services and Health 1995). The impetus for reform was escalating health care costs driven by an aging population and advances in technology, a shift in emphasis of health care delivery from the tertiary-to the primary-care sector (World Health Organization 2002), and demands by consumers for more patientcentered care.The principal national hypothesis that the trials were asked to test within a two-year time frame was the following: Coordinating the care of people with multiple service needs, who receive their care through individual care plans and funds pooled from existing commonwealth, state, and joint programs, will improve their health and well-being using existing resources. The main purpose of the trials was to "develop and test different service delivery and funding arrangements, and to determine the extent to which the coordinated care model contributes to• Improved client outcomes.

Background Sodium polystyrene sulfonate (SPS, Kayexalate) has been implicated in the development of intestinal necrosis. Sorbitol, added as a cathartic agent, may be primarily responsible. Previous studies have documented bowel necrosis primarily in postoperative, dialysis, and transplant patients. We sought to identify additional clinical characteristics among patients with probable SPS-induced intestinal necrosis. Methods Rhode Island Hospital surgical pathology records were reviewed to identify all gastrointestinal specimens reported as containing SPS crystals from December 1998 to June 2007. Patient demographics, medical comorbidities, and hospital courses of histologically verified cases of intestinal necrosis were extracted from the medical records. Results Twenty-nine patients with reports of SPS crystals were identified. Nine cases were excluded as incidental findings with normal mucosa. Nine patients were excluded as their symptoms began before SPS administration or because an alternate etiology for bowel ischemia was identified. Eleven patients had confirmed intestinal necrosis and a temporal relationship with SPS administration suggestive of SPS-induced necrosis. Only 2 patients were postoperative, and only 4 had end-stage renal disease (ESRD). All patients had documented hyperkalemia, received oral SPS, and developed symptoms of intestinal injury between 3 hours and 11 days after SPS administration. Four patients died. Conclusion Intestinal ischemia is a recognized risk of SPS in sorbitol. Our series highlights that patients may be susceptible even in the absence of ESRD, surgical intervention, or significant comorbidity.
