OP73 How can we Develop More Effective Public Health Interventions
Background A number of recent trials and systematic reviews of public health interventions have had disappointing conclusions despite a major investment in trials. An elegant evaluation design to test a poorly developed intervention is clearly unsatisfactory, so to what extent is the effectiveness of public health compromised by interventions that are poorly developed in the first place? Guidance on the development of complex interventions highli…
Patients’ experiences and views of an emergency and urgent care system
Background Surveys of patients’ experiences and views of health care usually focus on single services. During an unexpected episode of ill health, patients may make contact with different services and therefore experience care within an emergency and urgent care system. We developed the Urgent Care System Questionnaire and used it to describe patients’ experiences and views of an emergency and urgent care system in England. Methods A market resea…
PS10 The Appropriateness of, and Compliance with, Telephone Triage Decisions
Background Telephone triage plays an important role in managing demand for healthcare. In recent years there has been an increasing use of telephone triage in managing demand for unscheduled health care for general health problems. Policy makers, service providers and service evaluators are interested in the appropriateness of triage decisions in the context of offering an effective and safe service. In 2009 the Department of Health in England an…
South Yorkshire Cohort: A 'cohort trials facility' study of health and weight - Protocol for the recruitment phase
The South Yorkshire Cohort combines the strengths of the standard observational, longitudinal cohort study design with a population based cohort facility for multiple randomised controlled trials in a range of long term health and weight related conditions (including obesity). This infrastructure will allow the rapid and cheap identification and recruitment of patients, and facilitate the provision of robust evidence to inform the management and …
Three techniques for integrating data in mixed methods studies
Techniques designed to combine the results of qualitative and quantitative studies can provide researchers with more knowledge than separate analysis
A randomised controlled trial and cost-effectiveness evaluation of "booster" interventions to sustain increases in physical activity in middle-aged adults in deprived urban neighbourhoods
Current Controlled Trials: ISRCTN56495859; ClinicalTrials.gov: NCT00836459
The Quality of Mixed Methods Studies in Health Services Research
OBJECTIVES: To assess the quality of mixed methods studies in health services research (HSR). METHODS: We identified 118 mixed methods studies funded by the Department of Health in England between 1994 and 2004, and obtained proposals and/or final reports for 75. We applied a set of quality questions to both the proposal and report of each study, addressing the success of the study, the mixed methods design, the individual qualitative and quantit…
Multidisciplinary, Interdisciplinary, or Dysfunctional? Team Working in Mixed-Methods Research
Combining qualitative and quantitative methods in a single study-otherwise known as mixed-methods research-is common. In health research these projects can be delivered by research teams. A typical scenario, for example, involves medical sociologists delivering qualitative components and researchers from medicine or health economics delivering quantitative components. We undertook semistructured interviews with 20 researchers who had worked on mi…
Integration and Publications as Indicators of "Yield" From Mixed Methods Studies
A mixed methods study has the potential to produce knowledge that is unavailable to a qualitative study and a quantitative study undertaken independently. Any unique insight or ``yield'' from a mixed methods study may be difficult to assess in practice. However, given that integration of data or findings from different components of a study is a core characteristic of mixed methods research, two possible indicators of yield can be used: first, th…
Case-mix adjustment in non-randomised observational evaluations: The constant risk fallacy
Observational studies comparing groups or populations to evaluate services or interventions usually require case-mix adjustment to account for imbalances between the groups being compared. Simulation studies have, however, shown that case-mix adjustment can make any bias worse. One reason this can happen is if the risk factors used in the adjustment are related to the risk in different ways in the groups or populations being compared, and ignorin…
Cost effectiveness of a community based exercise programme in over 65 year olds: Cluster randomised trial
Objective: To assess the cost effectiveness of a community based exercise programme as a population wide public health intervention for older adults. Design: Pragmatic, cluster randomised community intervention trial. Setting: 12 general practices in Sheffield; four randomly selected as intervention populations, and eight as control populations. Participants: All those aged 65 and over in the least active four fifths of the population responding …
Using the SF-36 and Euroqol on an elderly population
Variation in demand for accident and emergency departments in England from 1974 to 1985
Over the period 1974-85 the range of mean annual new attendance rates at Accident and Emergency departments among English health districts was 36-673 per 1000 residents. The socio-economic diversity of these districts explained only one-third of the variation. The rates rose significantly (p less than 0.05) in 89 per cent of districts over the twelve years. Again, socio-economic variation only partly explained differences in district trends. Incr…
Effects of subsidising bus travel on the occurrence of road traffic casualties
Between 1975 and 1 April 1986, public transport by bus in the metropolitan county of South Yorkshire, England, was increasingly subsidised. Trends in road traffic accident casualties between 1974 and 1983 in all the six provincial English metropolitan counties have been compared in order to examine the possible effect of this unique subsidy on the incidence of road traffic accident casualties. During that period the total number of casualties in …
