ABSTRACT
BACKGROUND: Managed clinical networks have been used to coordinate chronic disease management across geographical regions in the United Kingdom. Our objective was to review how clinical networks and multidisciplinary team-working can be supported by Web-based information technology while clinical requirements continually change. METHODS: A Web-based population information system was developed and implemented in November 2000. The system incorporates local guidelines and shared clinical information based upon a national dataset for multispecialty use. Automated data linkages were developed to link to the master index database, biochemistry, eye screening, and general practice systems and hospital diabetes clinics. Web-based data collection forms were developed where computer systems did not exist. The experience over the first 10 years (to October 2010) was reviewed. RESULTS: The number of people with diabetes in Tayside increased from 9694 (2.5% prevalence) in 2001 to 18,355 (4.6%) in 2010. The user base remained stable (~400 users), showing a high level of clinical utility was maintained. Automated processes support a single point of data entry with 10,350 clinical messages containing 40,463 data items sent to external systems during year 10. The system supported quality improvement of diabetes care; for example, foot risk recording increased from 36% in 2007 to 73.3% in 2010. CONCLUSIONS: Shared-care datasets can improve communication between health care service providers. Web-based technology can support clinical networks in providing comprehensive, seamless care across a geographical region for people with diabetes. While health care requirements evolve, technology can adapt, remain usable, and contribute significantly to quality improvement and working practice.

OBJECTIVE: We sought to compare the risk of mortality and hospitalization between patients with and without diabetes following incident lower-extremity amputation (LEA). RESEARCH DESIGN AND METHODS: We performed a retrospective data-linkage review of all incident amputations between 1 January 1992 and 31 December 1995. Patients were categorized according to their diabetes status. Follow-up for mortality was until 1 January 2005 and until 31 March 1996 for hospitalization. RESULTS: Of 390 major-incident LEAs performed during the study period, 119 (30.5%) were in patients with diabetes and 271 (69.5%) were in nondiabetic subjects. The median time to death was 27.2 months in patients with diabetes compared with 46.7 months for patients without (P = 0.01). Diabetic subjects had a 55% greater risk of death than those without diabetes. The risk of developing congestive cardiac failure with diabetes was 2.26 (95% CI 1.12-4.57) and of further amputation was 1.95 (1.14-3.33) times that of a patient without diabetes after incident LEA. CONCLUSIONS: After LEA, patients with diabetes have an increased risk of death compared with nondiabetic patients. Efforts should be made to minimize these risks with aggressive treatment of cardiovascular risk factors and management of cardiac failure.
