How do people with cancer wish to be cared for in primary care? Serial discussion groups of patients and carers.
BACKGROUND: In most economically developed countries, patients, their informal and professional carers and policy makers are calling for more care in the community. OBJECTIVES: To involve patients with cancer, and their carers, in designing a framework for providing effective cancer care in primary care. METHODS: Two discussion groups comprising 18 people with current cancer and carers met monthly over a year in the south of Scotland. RESULTS: Patients with cancer and their carers identified five key times in the cancer journey as being especially significant from their perspective: around diagnosis, during treatment, after discharge, at recurrence and the final weeks. At each key time, there were five major issues of concern: information, communication, equity, a holistic approach and patient-centred care. Using these, the group members developed a checklist of recommended interventions for each stage in the illness trajectory and suggested how they might be implemented in primary care. Proactive and ongoing contact, if wished by the patient, was considered the central plank of cancer care in the community. CONCLUSIONS: Patients with cancer and their carers believe that there is an important and unique role for primary care in offering continuity of care and information that is patient-centred and holistic, throughout the cancer trajectory, from first presentation. This study successfully brought patient, carer and professional perspectives to the development of a care framework for primary care.

Mental representation in visual/haptic crossmodal memory: evidence from interference effects.
Two experiments used visual-, verbal-, and haptic-interference tasks during encoding (Experiment 1) and retrieval (Experiment 2) to examine mental representation of familiar and unfamiliar objects in visual/haptic crossmodal memory. Three competing theories are discussed, which variously suggest that these representations are: (a) visual; (b) dual-code-visual for unfamiliar objects but visual and verbal for familiar objects; or (c) amodal. The results suggest that representations of unfamiliar objects are primarily visual but that crossmodal memory for familiar objects may rely on a network of different representations. The pattern of verbal-interference effects suggests that verbal strategies facilitate encoding of unfamiliar objects regardless of modality, but only haptic recognition regardless of familiarity. The results raise further research questions about all three theoretical approaches.

Predicting colorectal cancer risk in patients with rectal bleeding.
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. SETTING: Primary care, southern England. METHOD: Symptom data were collected, using a self-completed questionnaire. Logistic regression techniques were used to determine predictors of colorectal cancer. RESULTS: There were 604 patients in the study and 22 (3.6%, 95% confidence interval [CI] = 2.0% to 5.2%) were diagnosed with colorectal cancer. Significant predictors of colorectal cancer were found to be age (<50 years: odds ratio [OR] = 1; 50-69 years: OR = 5.1, 95% CI = 1.4 to 18.6; > or = 70 years: OR = 8.2, 95% CI = 2.1 to 31.8) and blood mixed with the stool (Likelihood ratio [LR] 1.5; adjusted OR = 3.8; 95% CI = 1.4 to 10.5). Presence of haemorrhoids associated with bright red bleeding not mixed with stool reduced the likelihood of cancer (OR = 0.4, 95% CI = 0.1 to 1.2) but did not eliminate it--a cancer was present in 2% of patients with these symptoms. CONCLUSION: Patient-reported type of rectal bleeding as an isolated symptom has insufficient diagnostic value to be useful in general practice. By studying referred patients, we may even have overestimated its value. At best, it could be useful as a component of a composite symptom score to guide referral decisions.

The strength of graduated drivers license programs and fatalities among teen drivers and passengers.
OBJECTIVES: The purpose of this study is to investigate the effects of differentially stringent graduated drivers license programs on teen driver fatalities, day-time and night-time teen driver fatalities, fatalities of teen drivers with passengers present, and fatalities among teen passengers. METHODS: The study uses 1992-2002 data on motor vehicle fatalities among 15-17-year-old drivers from the Fatality Analysis Reporting System to identify the effects of "good", "fair", and "marginal" GDL programs based upon designations by the Insurance Institute for Highway Safety. Analysis is conducted using conditional negative binomial regressions with fixed effects. RESULTS: "Good" programs reduce total fatalities among young drivers by 19.4% (c.i. -33.0%, -5.9%). "Fair" programs reduce night-time young driver fatalities by 12.6% (c.i. -23.9%, -1.2%), but have no effect on day-time fatalities. "Marginal" programs had no statistically meaningful effect on driver fatalities. All three types of programs reduced teen passenger fatalities, but the effects of limitations on the number of passengers appear to have had only minimal effects in reducing fatalities among young drivers themselves. CONCLUSIONS: Stronger GDL programs are more effective than weaker programs in reducing teenage motor vehicle fatalities.

Impact of UK Colorectal Cancer Screening Pilot on hospital diagnostic services.
OBJECTIVE: To determine the impact of the UK Colorectal Cancer Screening Pilot on hospital services involved in the diagnosis of colorectal cancer (predominantly colonoscopy, double contrast barium enema and pathology). METHODS: Routine data from seven hospitals at two sites within Scotland and England participating in the Pilot were collected on activity levels and waiting times for key hospital services (GI medicine, surgery and radiology), plus questionnaire survey data from hospital consultants. RESULTS: Hospital colonoscopy activity increased by 31 per cent in Scotland and 21 per cent in England due to the investigation of faecal occult blood testing (FOBt) positive subjects. The demand for symptomatic (non-screening) colonoscopy also increased. Pilot-generated activity was less than predicted for barium enema services (maximum 3 per cent increase in service volume) but greater than expected for pathology, with approximately 200 specimens/month generated. Out-patient review of Pilot colonoscopy patients and associated administrative duties added substantially to overall GI service workload, but quantification was limited by the quality of routinely available data. There was a wide discrepancy in colonoscopy waiting times between screened and symptomatic patients, with predominantly longer waits for symptomatic patients: otherwise the quality of colonoscopy services appeared to improve. In any future national screening programme, follow-up of patients with adenomas will result in a further increase of 28 per cent in the number of colonoscopies generated (over and above colonoscopy for FOBt-positive subjects), adding substantially to overall workload. CONCLUSIONS: During the planning of any successful national colorectal cancer screening programme, careful consideration must be given to the wider aspects of workload associated with screening, as well as to the implementation of appropriate hospital data collection systems.

Microsystems in health care: Part 2. Creating a rich information environment.
BACKGROUND: A rich information environment supports the functioning of the small, functional, frontline units--the microsystems--that provide most health care to most people. Three settings represent case examples of how clinical microsystems use data in everyday practice to provide high-quality and cost-effective care. CASES: At The Spine Center at Dartmouth, Lebanon, New Hampshire, a patient value compass, a one-page health status report, is used to determine if the provided care and services are meeting the patient's needs. In Summit, New Jersey, Overlook Hospital's emergency department (ED) uses uses real-time process monitoring on patient care cycle times, quality and productivity indicator tracking, and patient and customer satisfaction tracking. These data streams create an information pool that is actively used in this ED icrosystem--minute by minute, hourly, daily, weekly, and annually--to analyze performance patterns and spot flaws that require action. The Shock Trauma Intensive Care Unit (STRICU), Intermountain Health Care, Salt Lake City, uses a data system to monitor the "wired" patient remotely and share information at any time in real time. Staff can complete shift reports in 10 minutes. DISCUSSION: Information exchange is the interface that connects staff to patients and staff to staff within the microsystem; microsystem to microsystem; and microsystem to macro-organization.

Microsystems in health care: Part 8. Developing people and improving work life: what front-line staff told us.
BACKGROUND: The articles in the Microsystems in Health Care series have focused on the success characteristics of high-performing clinical microsystems. Realization is growing about the importance of attracting, selecting, developing, and engaging staff. By optimizing the work of all staff members and by promoting a culture where everyone matters, the microsystem can attain levels of performance not previously experienced. CASE STUDY: At Massachusetts General Hospital Downtown Associates (Boston), a primary care practice, the human resource processes are specified and predictable, from a candidate's initial contact through each staff member's orientation, performance management, and professional development. Early on, the new employee receives materials about the practice, including a practice overview, his or her typical responsibilities, the performance evaluation program, and continuous quality improvement. Ongoing training and education are supported with skill labs, special education nights, and cross-training. The performance evaluation program, used to evaluate the performance of all employees, is completed during the 90-day orientation and training, quarterly for one year, and annually. CONCLUSION: Some health care settings enjoy high morale, high quality, and high productivity, but all too often this is not the case. The case study offers an example of a microsystem that has motivated its staff and created a positive and dynamic workplace.

Control and controllability: beliefs and behaviour in high and low expressed emotion relatives.
BACKGROUND: Expressed emotion (EE) is a measure of the family environment that is a well replicated psychosocial predictor of psychiatric relapse. Theoretical models of EE place heavy emphasis on the notion of control. We explored the extent to which high and low EE relatives made both attributions of control about patients and engaged in controlling behaviours. METHODS: Trained raters who were blind to information about EE coded interviews with 35 relatives of patients with schizophrenia and 42 relatives of patients with unipolar depression. Relatives were rated on two reliable scales that assessed relatives' tendencies to make illness controllability attributions and relatives' efforts to exert direct behavioural control over patients. RESULTS: In both the schizophrenia and depressed groups, high-EE relatives attributed more control to their ill family members than did low EE relatives. They also behaved in a more controlling manner. Examination of patients' clinical outcomes during a 9-month follow-up period revealed that high levels of behavioural control on the part of relatives significantly predicted relapse in patients with schizophrenia but not in patients with depression. CONCLUSIONS: These findings support the attribution-based model of EE. They further suggest that controlling behaviours on the part of relatives may mediate the EE-relapse link in schizophrenia. Such behaviours may be important targets for modification in family-based interventions for schizophrenia.

Deciding how NHS money is spent: a survey of general public and medical views.
OBJECTIVES: To examine the validity of the Prioritization Scoring Index (PSI) methodology by obtaining the views of our local population and clinicians regarding the criteria and weightings that should be used in deciding how NHS money is spent. BACKGROUND: We have used a PSI in Argyll and Clyde to allocate new money since 1996 and to determine priorities for our 1999/2000-2003/2004 Health Improvement Programme (HIP). Since the criteria and weightings for this methodology were developed subjectively, we sought to validate these by consulting local people and to change our methodology to take account of wider population views. METHODS: A postal questionnaire was sent to 1969 members of the general public, all 314 general practitioners and all 189 hospital consultants in Argyll and Clyde in March 1999. A reminder was sent after 4 weeks. Questions were asked about general funding and prioritization in the NHS and about specific issues relating to potential criteria for prioritization, including those used in our PSI methodology. Responses were analysed quantitatively in the Statistical Package for the Social Sciences (SPSS) and qualitatively through examination of the responses to open questions. RESULTS: The response rate was 51% for the general public and 71% for GPs and consultants. Respondents from the general public were broadly representative of the Argyll and Clyde population. The main findings were that: greater importance should be given to care that improves health, quality of life or prevents ill health rather than to cost, or to government and local health board priorities; half of the general public and most clinicians thought there should be a limit on NHS funding; extra money for the NHS should come from the national lottery (general public) or higher taxes on cigarettes and alcohol (clinicians); doctors should have the greatest influence in deciding how NHS money is spent; a higher priority should not be given to the health-care needs of younger people rather than older people. Our public and clinicians would allocate approximately 50% of the prioritization weighting to direct patient benefits, 25% to the cost of health-care and 25% to strategic health issues. CONCLUSIONS: Consideration of public and clinician views suggests that a revised PSI should place greater weight on benefits to patients and lower weight on the cost of health-care.
