Latest Technology Assessments and Appraisals
The causes and effects of socio-demographic exclusions from clinical trials (Bartlett) 168 pages, Volume 9, number 38
Study finds that the issue of exclusion from trials of women, older people and ethnic minorities has been relatively neglected in the UK research community and suggests the need for multi-disciplinary assessment of realistic options for trialists to address this.
Is hydrotherapy cost effective? A randomised controlled trial of combined hydrotherapy programmes compared with physiotherapy land techniques in children with juvenile idiopathic arthritis (Epps) 76 pages, Volume 9, number 39
This research demonstrates a beneficial effect from both combined hydrotherapy and land-based physiotherapy treatment and land-based physiotherapy treatment alone in juvenile idiopathic arthritis without any exacerbation of disease, but until further research is undertaken it is not possible to determine if the initiation and costs of building new hydrotherapy pools is justifiable or cost-effective in the long term.
The British Rheumatoid Outcome Study Group (BROSG) randomised controlled trial to compare the effectiveness and cost-effectiveness of aggressive versus symptomatic therapy in established rheumatoid arthritis (Symmons) 94 pages, Volume 9, number 34
This trial showed no additional benefit of aggressive treatment in patients with stable established rheumatoid arthritis (RA). Approximately one-third of current clinic attenders with stable RA could be managed in a shared care setting with an annual review by a rheumatologist and regular contact with a rheumatologist nurse.
Conceptual framework and systematic review of the effects of participants' and professionals' preferences in randomised controlled trials (King) 186 pages, Volume 9, number 35
This comprehensive study advances our understanding of how people's preferences affect randomised controlled trials, suggesting that the greatest impact is usually on recruitment of patients and how better information may help improve the external validation of trials.
The clinical effectiveness and cost-effectiveness of implantable cardioverter defibrillators: a systematic review (Bryant) 150 pages, Volume 9, number 36
A trial of problem-solving by community mental health nurses for anxiety, depression and life difficulties among general practice patients. The CPN_GP study (Kendrick) 104 pages, Volume 9, number 37
The study found that specialist mental health nurse support is no better than support from GPs for most patients with anxiety, depression and reactions to life difficulties, although there may be other roles in primary care that community mental health nurses could play effectively.

Pressure ulcers: The management of pressure ulcers in primary and secondary care
The quick reference guide below summarises the recommendations made in:
Because of the overlap between these guidelines, particularly in the areas of risk assessment and the use of pressure relieving devices, NICE’s new quick reference guide combines the major elements of all the pressure ulcer guidelines in a single algorithm to provide one clear source of information on pressure ulcer management and prevention. Accordingly, NICE’s existing guideline Pressure ulcer prevention has been withdrawn.
Management of atopic eczema in children from birth up to the age of 10 years

Practical lessons for dealing with inequalities in health impact assessment
This publication is a companion to Addressing inequalities through health impact assessment (Taylor et al., 2003a), which described what a focus on inequalities could achieve, offered case study examples, and outlined promising practice. This bulletin discusses recent publications and presents a further two case studies that attempt to address health inequalities through the use of HIA.
Incentives for reform in the NHS: An assessment of current incentives in the south-east London health economy
Following the Governments vision for the NHS, and incentives to drive change in the NHS as detailed in the NHS Plan, the King’s Fund has published a report which considers whether the current system of incentives is ‘fit for purpose’. Or, on the contrary, do they work against each other, making it harder for local organisations to meet all the targets and objectives they have been set? To answer this question the research has examined one health economy – south-east London – as a case study.
The key questions that the research in south-east London investigated were:
The research examined four areas.
The project used three methods: a literature review, interviews and quantitative analysis.
The interviews were conducted with chief executives, chairs and finance directors from each trust in the South East London Strategic Health Authority.

Liker H., Hungin P., Wiklund I. Managing gastroesophageal reflux disease in primary care: the patient perspective. J Am Board Fam Pract. 2005 Sep-Oct;18(5):393-400
Gastroesophageal reflux disease (GERD) is a chronic disease that affects up to 20% of the population of Western countries and accounts for around 5% of a primary-care physician’s workload. A better understanding of how GERD affects many aspects of patients’ lives may aid the management of patients in primary care. We conducted a systematic review of the effect of GERD on health-related quality of life (HRQL) in the primary-care setting and in the community. Validated questionnaires have shown that GERD patients consulting in primary care experience substantial reductions in both physical and psychosocial aspects of HRQL, as well as work productivity. Impairments in HRQL are seen whether or not reflux esophagitis or Barrett’s esophagus is present on endoscopy, and are comparable with or worse than those seen in patients with other chronic diseases such as heart disease, diabetes, and cancer. Surveys in primary care and in the community highlight disrupted sleep, reduced concentration at work, and interference with physical activities such as exercise, housework, and gardening. Psychosocial aspects of patient well-being are also impaired, including enjoyment of social gatherings, intimacy, sex, and many individuals with GERD remain worried about the underlying cause of their symptoms. In conclusion, many aspects of HRQL are impaired in GERD patients. The primary-care physician is uniquely placed to assess and address the impact of GERD on patients’ lives.
Tylee A., Gandhi P. The importance of somatic symptoms in depression in primary care. Prim Care Companion J Clin Psychiatry. 2005;7(4):167-76
Objective: Patients with depression present with psychological and somatic symptoms, including general aches and pains. In primary care, somatic symptoms often dominate. A review of the literature was conducted to ascertain the importance of somatic symptoms in depression in primary care. Data sources and extraction: MEDLINE, EMBASE, and PsychLIT/PsychINFO databases (1985–January 2004) were searched for the terms depression, depressive, depressed AND physical, somatic, unexplained symptoms, complaints, problems; somatised, somatized symptoms; somatisation, somatization, somatoform, psychosomatic; pain; recognition, underrecognition; diagnosis, underdiagnosis; acknowledgment, underacknowledgment; treatment, undertreatment AND primary care, ambulatory care; primary physician; office; general practice; attribution, reattribution; and normalising, normalizing. Only English-language publications and abstracts were considered. Study selection: More than 80 papers related to somatic symptoms in depression were identified using the content of their titles and abstracts. Data synthesis: Approximately two thirds of patients with depression in primary care present with somatic symptoms. These patients are difficult to diagnose, feel an increased burden of disease, rely heavily on health care services, and are harder to treat. Patient and physician factors that prevent discussion of psychological symptoms during consultations must be overcome. Conclusions: Educational initiatives that raise awareness of somatic symptoms in depression and help patients to reattribute these symptoms should help to improve the recognition of depression in primary care.
van Hout H.P., Nijpels G., van Marwijk H.W., Jansen A.P., van 't Veer P.J., Tybout W., Stalman W.A. Design and pilot results of a single blind randomized controlled trial of systematic demand-led home visits by nurses to frail elderly persons in primary care. BMC Geriatr. 2005 Sep 8;5(1):11
Background The objective of this article is to describe the design of an evaluation of the cost-effectiveness of systematic home visits by nurses to frail elderly primary care patients. Pilot objectives were: 1. To determine the feasibility of postal multidimensional frailty screening instruments; 2. to identify the need for home visits to elderly. Methods Main study: The main study concerns a randomized controlled in primary care practices (PCP) with 18 months follow-up and blinded PCPs. Frail persons aged 75 years or older and living at home but neither terminally ill nor demented from 33 PCPs were eligible. Trained community nurses (1) visit patients at home and assess the care needs with the Resident Assessment Instrument-Home Care, a multidimensional computerized geriatric assessment instrument, enabling direct identification of problem areas; (2) determine the care priorities together with the patient; (3) design and execute interventions according to protocols; (4) and visit patients at least five times during a year in order to execute and monitor the care-plan. Controls receive usual care. Outcome measures are Quality of life, and Quality Adjusted Life Years; time to nursing home admission; mortality; hospital admissions; health care utilization. Pilot 1: Three brief postal multidimensional screening measures to identify frail health among elderly persons were tested on percentage complete item response (selected after a literature search): 1) Vulnerable Elders Screen, 2) Strawbridge's frailty screen, and 3) COOP-WONCA charts. Pilot 2: Three nurses visited elderly frail patients as identified by PCPs in a health center of 5400 patients and used an assessment protocol to identify psychosocial and medical problems. The needs and experiences of all participants were gathered by semi-structured interviews. Discussion The design holds several unique elements such as early identification of frail persons combined with case-management by nurses. From two pilots we learned that of three potential postal frailty measures, the COOP-WONCA charts were completed best by elderly and that preventive home visits by nurses were positively evaluated to have potential for quality of care improvement.

In a previous Statistics Note, we defined terms such as experimental event risk (EER), control event risk (CER), absolute risk reduction (ARR), and number needed to treat (NNT).1 Estimates such as ARR and NNT alone, however, do not describe the uncertainty around the results. P values and CIs provide additional information to help us determine whether the results are both clinically and statistically significant (table 1).

Trials
Phase III trial of Canvaxin for patients with stage III melanoma discontinued
According to BioSpace, a Phase III clinical trial of Canvaxin in patients with Stage III melanoma has been stopped, following the recommendation of the independent Data and Safety Monitoring Board (DSMB). The board recently completed its planned, third, interim analysis of the data from this study and concluded that the data are unlikely to provide significant evidence of an overall survival benefit for patients with Stage III melanoma treated with Canvaxin vs. placebo.

'Statin drugs could cut heart attacks by third'
Wider use of statins could cut heart attacks or stroke by a third, reported three newspapers (27 September 2005). The reports are based on a well conducted study which found that statin therapy could benefit people at risk of heart attack or stroke even if their cholesterol level is not high.
National Library for Health - Focus On
Value is a really difficult thing to define. There are some great quotes about value, like the famous Oscar Wilde definition of a cynic as a man who knows the price of everything and the value of nothing. Across the water in the USA, HL Mencken quipped that the chief value of money lies in the fact that one lives in a world in which it is overestimated.
Neither of which is particularly useful in exploring what value means in healthcare. There is a narrow definition, that of a cost per quality adjusted life year (QALY). Informally we tend to accept in the UK that anything with a cost per QALY of £30,000 or less is good value, and if it is more than that it is poor value.
That's fine as far as it goes. The trouble is that calculating a cost per QALY is not always the easiest thing in the world. First you need a cost, and then you need a QALY. Given that in some circumstances there can be considerable uncertainty, then opportunities for disagreement are probable - they occur when cost is high and quality of life low, with uncertainty in both.
