An evaluation of the second round of faecal occult blood (FOB) screening in the English site of the UK Colorectal Cancer Screening Pilot (comprising the Bowel Cancer Screening Pilot based in Rugby, general practices in four Primary Care Trusts, and their associated hospitals) was carried out. A total of 127 746 men and women aged 50–69 and registered in(More)
STOP is a Natural Language Generation (NLG) system that generates short tailored smoking cessation letters, based on responses to a four-page smoking questionnaire. A clinical trial with 2553 smokers showed that STOP was not effective; that is, recipients of a non-tailored letter were as likely to stop smoking as recipients of a tailored letter. In this(More)
Stage at diagnosis and survival from cancer vary according to where people live, suggesting some may have delays in diagnosis. The aim of this study was to determine if time from presentation to treatment was longer for colorectal and breast cancer patients living further from cancer centres, and identify other important factors in delay. Data were(More)
OBJECTIVES To develop and evaluate, in a primary care setting, a computerised system for generating tailored letters about smoking cessation. DESIGN Randomised controlled trial. SETTING Six general practices in Aberdeen, Scotland. PARTICIPANTS 2553 smokers aged 17 to 65. INTERVENTIONS All participants received a questionnaire asking about their(More)
The stop system generates personalised smoking-cessation letters, using as input responses to a smoking questionnaire. Generating personalised patient-information material is an area of growing interest to the medical community, since for many people changing health-related behaviour is the most effective possible medical intervention. While previous ai(More)
The STOP system, which generates personalised smoking-cessation letters, was evaluated by a randomised controlled clinical trial. We believe this is the largest and perhaps most rigorous task effectiveness evaluation ever performed on an NLG system. The detailed results of the clinical trial have been presented elsewhere, in the medical literature. In this(More)
BACKGROUND Rectal bleeding is an important symptom of colorectal cancer but has low predictive value in primary care. AIM To determine which characteristics of rectal bleeding, along with other factors, are predictive of colorectal cancer. DESIGN OF STUDY Observation study of patients with rectal bleeding referred to an open-access diagnostic clinic. (More)
Natural language generation (nlg) systems are computer software systems that produce texts in English and other human languages, often from non-linguistic input data. nlg systems, like most ai systems, need substantial amounts of knowledge. However, our experience in two nlg projects suggests that it is difficult to acquire correct knowledge for nlg(More)
Background:British 5-year survival from colorectal cancer (CRC) is below the European average, but the reasons are unclear. This study explored if longer provider delays (time from presentation to treatment) were associated with more advanced stage disease at diagnosis and poorer survival.Methods:Data on 958 people with CRC were linked with the Scottish(More)
