Effectiveness of nurse-led brief alcohol intervention: a cluster randomized controlled trial.

AIM: This paper reports an evaluation of the effectiveness and cost-effectiveness of nurse-led screening and brief intervention in reducing excessive alcohol consumption among patients in primary health care. BACKGROUND: Excessive alcohol consumption is a major source of social, economic and health problems. However, such consumption is responsive to brief alcohol intervention. To date, brief intervention research in primary health care has focused on general practitioner-led interventions, and there is only circumstantial evidence of effectiveness in nurse-led interventions. However, nurses are increasingly taking a lead in health promotion work in primary care. METHODS: A pragmatic cluster-randomized controlled trial was carried out between August 2000 and June 2003 to evaluate the effects of a brief intervention compared with standard advice (control condition). A total of 40 general practice clusters (intervention = 21 and control = 19) recruited 127 patients (intervention = 67 and control = 60) to the trial. Excessive consumption was identified opportunistically via the Alcohol Use Disorders Identification Test. After baseline assessment, patients received either a 5-10 minutes brief intervention using the 'Drink-Less' protocol or standard advice (control condition). Follow-up occurred at 6 and 12 months postintervention. RESULTS: Analysis of variance weighted for cluster size revealed no statistically significant differences between intervention and control patients at follow up. A majority of patients in both conditions reduced their alcohol consumption between assessment and subsequent measurement. Economic analysis suggested that the brief intervention led to no statistically significant changes in subsequent health service resource use relative to standard treatment. CONCLUSION: The brief intervention evaluated in this trial had no effect over standard advice delivered by nurses in primary health care. However, there was a reduction in excessive drinking across both arms of the trial over time. Due to nurse drop-out, this trial was significantly underpowered. Future research should explore barriers to nurses' involvement in research trials, particularly with an alcohol focus. A larger trial is required to evaluate the effectiveness of nurse-led screening and brief alcohol intervention in primary care.

A comparison of the grade of membership measure with alternative health indicators in explaining costs for older people.

An important focus in empirical econometric studies of health care concerns estimation of the relationship with health. This paper describes a non-parametric technique, the grade of membership (GoM) procedure, which is used to construct summary indicators of health. Health status is also assessed using three alternative measures commonly employed in the literature: an index of problems of activities of daily living (ADL), an index of health conditions and overall self-rated health. Using data from a sample of frail older people, the relationship between costs and different measures of health are estimated using ordinary least squares (OLS) and instrumental variables (IV) methods. The results show that health influences costs more strongly than other variables, an effect which persists after controlling for potential endogeneity. It is shown that health can be usefully classified using GoM techniques. An alternative measure, based on an index of ADL, also performs well. Measures based on overall self-assessed health and the number of health conditions present were less satisfactory. Although health indicators derived from GoM techniques may be more theoretically attractive, in terms of capturing more fully the multidimensional nature of health, simpler alternatives such as those based on ADL indices may offer practical computational advantages.

Chained time trade-off and standard gamble methods. Applications in oesophageal cancer.

It may be difficult to value palliative health states using health state valuation methods such as the time trade-off (TTO) and standard gamble (SG) where health states are traditionally valued relative to perfect/good health and death. Chained methods have been developed to help in this context. However, few studies have compared the values produced by chained TTO and SG methods. To address this issue, a study was conducted to measure the health state values associated with oesophageal cancer using chained TTO and SG techniques. The methods were found to be acceptable amongst the sample respondents, who had previously been treated for oesophageal cancer. There were no significant differences between the health state values produced by the TTO and the SG methods. Within each method, however, there were significant differences between the health states valued. It is concluded that the use of health state valuation techniques such as the TTO and SG is feasible amongst people with a history of oesophageal cancer.

Promoting brief alcohol intervention by nurses in primary care: a cluster randomised controlled trial.

This trial evaluated the clinical impact and cost-effectiveness of strategies promoting screening and brief alcohol intervention (SBI) by nurses in primary care. Randomisation was at the level of the practice and the interventions were: written guidelines (controls, n=76); outreach training (n=68); and training plus telephone-based support (n=68). After 3 months, just 39% of controls implemented the SBI programme compared to 74% of nurses in trained practices and 71% in trained and supported practices. Controls also screened fewer patients and delivered fewer brief interventions to risk drinkers than other colleagues. However, there was a trade-off between the extent and the appropriateness of brief intervention delivery with controls displaying the least errors in overall patient management. Thus cost-effectiveness ratios (cost per patient appropriately treated) were similar between the three strategies. Given the potential for anxiety due to misdirected advice about alcohol-related risk, the balance of evidence favoured the use of written guidelines to promote SBI by nurses in primary care.

Does an early increased-intensity interdisciplinary upper limb therapy programme following acute stroke improve outcome?

OBJECTIVE: To determine whether an early increased-intensity upper limb therapy programme following acute stroke improves outcome. DESIGN: A randomized controlled trial. SETTING: A stroke unit which provides acute care and rehabilitation for all stroke admissions. SUBJECTS: One hundred and twenty-three patients who had had a stroke causing upper limb impairment within the previous 10 days. INTERVENTION: The intervention group received stroke unit care plus enhanced upper limb rehabilitation provided jointly by a physiotherapist and occupational therapist, commencing within 10 days of stroke, and available up to 30 minutes/day, five days/week for six weeks. The control group received stroke unit care. MAIN OUTCOME MEASURES: The primary outcome measure was the Action Research Arm Test (ARAT) three months after stroke. SECONDARY OUTCOME MEASURES: Motricity Index; Frenchay Arm Test; upper limb pain; Barthel ADL Index; Nottingham E-ADL Scale; and costs to health and social services at three and six months after stroke. RESULTS: There were no differences in outcomes between the intervention and control groups three and six months after stroke. During the intervention period the intervention group received a median of 29 minutes of enhanced upper limb therapy per working day as inpatients. The total amount of inpatient physiotherapy and occupational therapy received by the intervention group was a median of 52 minutes per working day during the intervention period and 38 minutes per working day for the control group (p = 0.001). There were no differences in service costs. CONCLUSIONS: An early increased-intensity interdisciplinary upper limb therapy programme jointly provided by a physiotherapist and occupational therapist did not improve outcome after stroke. The actual difference in the amount of therapy received by intervention and control groups was less than planned due to a competitive therapy bias.

Informal caregiving for frail older people at home and in long-term care institutions: who are the key supporters?

This paper describes the extent of the informal caregiving unit for older people who are physically or mentally frail living in private households or resident in long-term care institutions using cross-sectional analysis of survey data. A total of 1444 people aged 65 years or more registered with a general practitioner (GP) in four areas in England and, consenting to the study, were screened for mental or physical frailty. Of 1127 older subjects living at home 7% reported receiving no informal support, 15% had a paid supporter only and 78% nominated a key informal supporter who helped with defined activities of daily living of whom 650 (74%) were interviewed. Only 13% nominated more than one informal supporter. Key supporters were spouses (38%), daughters (30%), sons (9%), daughters-in-law (4%), other relatives (11%) and friends and neighbours (8%). Of 317 frail older people resident in long-term care institutions 175 (55%) received a main visitor at least once a week of whom 132 (75%) were interviewed. Main visitors were spouses (11%), daughters (36%), sons (23%), daughters-in-law (2%), other relatives (24%) and friends (4%). Qureshi & Walker's (1989) hierarchical, decision-making model for selecting informal caregivers was applied to the data and correctly identified 85% of key informal supporters and 79% of main visitors interviewed. This large-scale comprehensive survey of informal care for frail older people supports earlier small-scale localized studies highlighting the key role of spouses and daughters in the provision of informal support. Families of frail older people provide the support to maintain people at home.
