OBJECTIVE The uptake of research findings into routine health care is a haphazard and unpredictable process. The usefulness of the results of implementation studies is limited, due in part to the lack of an underlying framework of the important dimensions of research studies in this area and the healthcare settings within which they are conducted and may(More)
BACKGROUND There is growing interest in the use of cognitive, behavioural, and organisational theories in implementation research. However, the extent of use of theory in implementation research is uncertain. METHODS We conducted a systematic review of use of theory in 235 rigorous evaluations of guideline dissemination and implementation studies(More)
OBJECTIVES To address issues about data monitoring committees (DMCs) for randomised controlled trials (RCTs). DATA SOURCES Electronic databases. Handsearching of selected books. Personal contacts with experts in the field. REVIEW METHODS Systematic literature reviews of DMCs and small group processes in decision-making; sample surveys of: reports of(More)
BACKGROUND The aim of the study was to review systematically the literature measuring the accuracy of routine UK hospital statistics that classify patients on discharge. METHODS A systematic review was carried out of studies comparing routine discharge statistics about an episode of hospital care with the original medical record. Dual quality assessment(More)
Health services research consistently demonstrates a gap between research-based best clinical practice and what doctors actually do. Traditionally, the profession of medicine has behaved as if dissemination of research findings in peer-reviewed journals will eliminate this gap, even though professionals typically have less than 1 hour per week to read. This(More)
BACKGROUND Psychological models can be used to understand and predict behaviour in a wide range of settings. However, they have not been consistently applied to health professional behaviours, and the contribution of differing theories is not clear. The aim of this study was to explore the usefulness of a range of psychological theories to predict health(More)
BACKGROUND The results of randomised controlled trials can be usefully illuminated by studies of the processes by which they achieve their effects. The Theory of Planned Behaviour (TPB) offers a framework for conducting such studies. This study used TPB to explore the observed effects in a pragmatic cluster randomised controlled trial of a structured recall(More)
BACKGROUND Biomedical research constantly produces new findings but these are not routinely translated into health care practice. One way to address this problem is to develop effective interventions to translate research findings into practice. Currently a range of empirical interventions are available and systematic reviews of these have demonstrated that(More)
A consistent finding in health services research is the report of uneven uptake of research findings. Implementation trials have a variable record of success in effectively influencing clinicians' behaviour. A more systematic approach may be to conduct Intervention Modelling Experiments before service-level trials, examining intervention effects on 'interim(More)
Snow water equivalent (SWE) is a critical parameter for climatological and hydrological studies over northern high-latitude areas. In this paper, we study the usability of the Helsinki University of Technology (HUT) snow emission model for the estimation of SWE in a Canadian boreal forest environment. The experimental data (airborne passive microwave and(More)
