OBJECTIVE To develop a method of identifying patients at high risk of readmission to hospital in the next 12 months for practical use by primary care trusts and general practices in the NHS in England. DATA SOURCES Data from hospital episode statistics showing all admissions in NHS trusts in England over five years, 1999-2000 to 2003-4; data from the 2001(More)
OBJECTIVES To test the performance of new variants of models to identify people at risk of an emergency hospital admission. We compared (1) the impact of using alternative data sources (hospital inpatient, A&E, outpatient and general practitioner (GP) electronic medical records) (2) the effects of local calibration on the performance of the models and (3)(More)
OBJECTIVE To assess the effect of home based telehealth interventions on the use of secondary healthcare and mortality. DESIGN Pragmatic, multisite, cluster randomised trial comparing telehealth with usual care, using data from routine administrative datasets. General practice was the unit of randomisation. We allocated practices using a minimisation(More)
Existing ML-like languages guarantee type-safety, ensuring memory safety and protecting the invariants of abstract types, but only within single executions of single programs. Distributed programming is becoming ever more important, and should benefit even more from such guarantees. In previous work on theoretical calculi and the Acute prototype language we(More)
OBJECTIVES To develop an algorithm for identifying inpatients at high risk of re-admission to a National Health Service (NHS) hospital in England within 30 days of discharge using information that can either be obtained from hospital information systems or from the patient and their notes. DESIGN Multivariate statistical analysis of routinely collected(More)
OBJECTIVE to assess the impact of telecare on the use of social and health care. Part of the evaluation of the Whole Systems Demonstrator trial. PARTICIPANTS AND SETTING a total of 2,600 people with social care needs were recruited from 217 general practices in three areas in England. DESIGN a cluster randomised trial comparing telecare with usual care,(More)
OBJECTIVES To develop a formula for allocating resources for commissioning hospital care to all general practices in England based on the health needs of the people registered in each practice DESIGN Multivariate prospective statistical models were developed in which routinely collected electronic information from 2005-6 and 2006-7 on individuals and the(More)
BACKGROUND This retrospective study will assess the extent to which multidisciplinary case management in the form of virtual wards (VWs) leads to changes in the use of health care and social care by patients at high risk of future unplanned hospital admission. VWs use the staffing, systems and daily routines of a hospital ward to deliver coordinated care to(More)
Project aims The aim of this project was to increase the performance of the Acute programming language by compiling it into O'Caml bytecode. We were unsure whether many of the new facilities for distributed programming were amenable to an efficient, low-level implementation. This project has direct implications on the future use of the Acute features in(More)
