Theories of behaviour change synthesised into a set of theoretical groupings: introducing a thematic series on the theoretical domains framework.

Behaviour change is key to increasing the uptake of evidence into healthcare practice. Designing behaviour-change interventions first requires problem analysis, ideally informed by theory. Yet the large number of partly overlapping theories of behaviour makes it difficult to select the most appropriate theory. The need for an overarching theoretical framework of behaviour change was addressed in research in which 128 explanatory constructs from 33 theories of behaviour were identified and grouped. The resulting Theoretical Domains Framework (TDF) appears to be a helpful basis for investigating implementation problems. Research groups in several countries have conducted TDF-based studies. It seems timely to bring together the experience of these teams in a thematic series to demonstrate further applications and to report key developments. This overview article describes the TDF, provides a brief critique of the framework, and introduces this thematic series.In a brief review to assess the extent of TDF-based research, we identified 133 papers that cite the framework. Of these, 17 used the TDF as the basis for empirical studies to explore health professionals’ behaviour. The identified papers provide evidence of the impact of the TDF on implementation research. Two major strengths of the framework are its theoretical coverage and its capacity to elicit beliefs that could signify key mediators of behaviour change. The TDF provides a useful conceptual basis for assessing implementation problems, designing interventions to enhance healthcare practice, and understanding behaviour-change processes. We discuss limitations and research challenges and introduce papers in this series.

A knowledge creation info-structure to acquire and crystallize the tacit knowledge of health-care experts

Tacit knowledge of health-care experts is an important source of experiential know-how, yet due to various operational and technical reasons, such health-care knowledge is not entirely harnessed and put into professional practice. Emerging knowledge-management (KM) solutions suggest strategies to acquire the seemingly intractable and nonarticulated tacit knowledge of health-care experts. This paper presents a KM methodology, together with its computational implementation, to 1) acquire the tacit knowledge possessed by health-care experts; 2) represent the acquired tacit health-care knowledge in a computational formalism-i.e., clinical scenarios-that allows the reuse of stored knowledge to acquire tacit knowledge; and 3) crystallize the acquired tacit knowledge so that it is validated for health-care decision-support and medical education systems.

Knowledge translation research: the science of moving research into policy and practice.

Research findings will not change health outcomes unless health care organizations, systems, and professionals adopt them in practice. Knowledge translation research is the scientific study of the methods to promote the uptake of research findings by patients, health care providers, managers, and policy makers. Many forms of enquiry addressing different questions are needed to develop the evidence base for knowledge translation. In this paper we will present a description of the broad scope of knowledge translation research with a reflection on activities needed to further develop the science of knowledge translation. Consideration of some of the shared research challenges facing the fields of knowledge translation and continuing professional development will also be presented.

Bridging the Gap: Knowledge Seeking and Sharing in a Virtual Community of Emergency Practice

Disparities exist between rural and urban emergency departments with respect to knowledge resources such as online journals and clinical specialists. As knowledge is a critical element in the delivery of quality care, a web-based learning project was proposed to address the knowledge needs of emergency clinicians. One objective of this project was to evaluate the effectiveness of the online environment for knowledge exchange among rural and urban emergency clinicians. Descriptive and content analysis of the online discussion board revealed 202 postings with rural participants contributing the largest number of postings (75%; 152/202). Postings were used to establish a clinical presence (87/202), seek clinical information (52/202), and share clinical information (63/202). Postintervention survey results indicate that this modality introduced participants to new clinical experts and resources. The results provide direction for design of a virtual community of practice, which may reduce current knowledge resource disparities.

Understanding the Canadian adult CT head rule trial: use of the theoretical domains framework for process evaluation

BackgroundThe Canadian CT Head Rule was prospectively derived and validated to assist clinicians with diagnostic decision-making regarding the use of computed tomography (CT) in adult patients with minor head injury. A recent intervention trial failed to demonstrate a decrease in the rate of head CTs following implementation of the rule in Canadian emergency departments. Yet, the same intervention, which included a one-hour educational session and reminders at the point of requisition, was successful in reducing cervical spine imaging rates in the same emergency departments. The reason for the varied effect of the intervention across these two behaviours is unclear. There is an increasing appreciation for the use of theory to conduct process evaluations to better understand how strategies are linked with outcomes in implementation trials. The Theoretical Domains Framework (TDF) has been used to explore health professional behaviour and to design behaviour change interventions but, to date, has not been used to guide a theory-based process evaluation. In this proof of concept study, we explored whether the TDF could be used to guide a retrospective process evaluation to better understand emergency physicians’ responses to the interventions employed in the Canadian CT Head Rule trial.MethodsA semi-structured interview guide, based on the 12 domains from the TDF, was used to conduct telephone interviews with project leads and physician participants from the intervention sites in the Canadian CT Head Rule trial. Two reviewers independently coded the anonymised interview transcripts using the TDF as a coding framework. Relevant domains were identified by: the presence of conflicting beliefs within a domain; the frequency of beliefs; and the likely strength of the impact of a belief on the behaviour.ResultsEight physicians from four of the intervention sites in the Canadian CT Head Rule trial participated in the interviews. Barriers likely to assist with understanding physicians’ responses to the intervention in the trial were identified in six of the theoretical domains: beliefs about consequences; beliefs about capabilities; behavioural regulation; memory, attention and decision processes; environmental context and resources; and social influences. Despite knowledge that the Canadian CT Head Rule was highly sensitive and reliable for identifying clinically important brain injuries and strong beliefs about the benefits for using the rule, a number of barriers were identified that may have prevented physicians from consistently applying the rule.ConclusionThis proof of concept study demonstrates the use of the TDF as a guiding framework to design a retrospective theory-based process evaluation. There is a need for further development and testing of methods for using the TDF to guide theory-based process evaluations running alongside behaviour change intervention trials.

Improving child protection in the emergency department: a systematic review of professional interventions for health care providers.

OBJECTIVESnThis systematic review evaluated the effectiveness of professional and organizational interventions aimed at improving medical processes, such as documentation or clinical assessments by health care providers, in the care of pediatric emergency department (ED) patients where abuse was suspected.nnnMETHODSnA search of electronic databases, references, key journals, and conference proceedings was conducted and primary authors were contacted. Studies whose purpose was to evaluate a strategy aimed at improving ED clinical care of suspected abuse were included. Study methodologic quality was assessed by two independent reviewers. One reviewer extracted the data, and a second checked for completeness and accuracy.nnnRESULTSnSix studies met the inclusion criteria: one randomized controlled trial (RCT), one quasi-RCT, and four observational studies. Study quality ranged from modest (observational studies) to good (trials). Variation in study interventions and outcomes limited between-study comparisons. The quasi-RCT supported self-instructional education kits as a means to improve physician knowledge for both physical abuse (mean +/- standard deviation [SD] pretest score = 13.12 +/- 2.36; mean +/- SD posttest score = 18.16 +/- 1.64) and sexual abuse (mean +/- SD pretest score = 10.81 +/- 3.20; mean +/- SD posttest score = 18.45 +/- 1.79). Modest-quality observational studies evaluated reminder systems for physician documentation with similar results across studies. Compared to standard practice, chart checklists paired with an educational program increased physician consideration of nonaccidental burns in burn cases (59% increase), documentation of time of injury (36% increase), and documentation of consistency (53% increase) and compatibility (55% increase) of reported histories. Decisional flow charts for suspected physical abuse also increased documentation of nonaccidental physical injury (69.5% increase; p < 0.0001) and had a similar significant effect as checklists on increasing documentation of history consistency and compatibility (69.5 and 70.0% increases, respectively; p < 0.0001) when compared to standard practice. No improvements were noted in these studies for documentation of consultations or current status with child protective services. The introduction of a specialized team and crisis center to standardize practice had little effect on physician documentation, but did increase documentation of child protective services involvement (22.7% increase; p < 0.005) and discharge status (23.7% increase; p < 0.02). Referral to social services increased in one study following the introduction of a chart checklist (8.6% increase; p = 0.018). A recently conducted multisite RCT did not support observational findings, reporting no significant effect of educational sessions and/or a chart checklist on ED practices.nnnCONCLUSIONSnThe small number of studies identified in this review highlights the need for future quality studies that address care of a vulnerable clinical population. While moderate-quality observational studies suggest that education and reminder systems increase clinical knowledge and documentation, these findings are not supported by a multisite randomized trial. The limited theoretical base for conceptualizing change in health care providers and the influence of the ED environment on clinical practice are limitations to this current evidence base.

Blame, Shame, and Lack of Support: A Multilevel Study on Obesity Management

In this research, we examined the experiences of individuals living with obesity, the perceptions of health care providers, and the role of social, institutional, and political structures in the management of obesity. We used feminist poststructuralism as the guiding methodology because it questions everyday practices that many of us take for granted. We identified three key themes across the three participant groups: blame as a devastating relation of power, tensions in obesity management and prevention, and the prevailing medical management discourse. Our findings add to a growing body of literature that challenges a number of widely held assumptions about obesity within a health care system that is currently unsupportive of individuals living with obesity. Our identification of these three themes is an important finding in obesity management given the diversity of perspectives across the three groups and the tensions arising among them.

Identifying the domains of context important to implementation science: a study protocol

BackgroundThere is growing recognition that “context” can and does modify the effects of implementation interventions aimed at increasing healthcare professionals’ use of research evidence in clinical practice. However, conceptual clarity about what exactly comprises “context” is lacking. The purpose of this research program is to develop, refine, and validate a framework that identifies the key domains of context (and their features) that can facilitate or hinder (1) healthcare professionals’ use of evidence in clinical practice and (2) the effectiveness of implementation interventions.Methods/designA multi-phased investigation of context using mixed methods will be conducted. The first phase is a concept analysis of context using the Walker and Avant method to distinguish between the defining and irrelevant attributes of context. This phase will result in a preliminary framework for context that identifies its important domains and their features according to the published literature. The second phase is a secondary analysis of qualitative data from 13 studies of interviews with 312 healthcare professionals on the perceived barriers and enablers to their application of research evidence in clinical practice. These data will be analyzed inductively using constant comparative analysis. For the third phase, we will conduct semi-structured interviews with key health system stakeholders and change agents to elicit their knowledge and beliefs about the contextual features that influence the effectiveness of implementation interventions and healthcare professionals’ use of evidence in clinical practice. Results from all three phases will be synthesized using a triangulation protocol to refine the context framework drawn from the concept analysis. The framework will then be assessed for content validity using an iterative Delphi approach with international experts (researchers and health system stakeholders/change agents).DiscussionThis research program will result in a framework that identifies the domains of context and their features that can facilitate or hinder: (1) healthcare professionals’ use of evidence in clinical practice and (2) the effectiveness of implementation interventions. The framework will increase the conceptual clarity of the term “context” for advancing implementation science, improving healthcare professionals’ use of evidence in clinical practice, and providing greater understanding of what interventions are likely to be effective in which contexts.

Emergency health care use and follow-up among sociodemographic groups of children who visit emergency departments for mental health crises

Background: Previous studies of differences in mental health care associated with children’s sociodemographic status have focused on access to community care. We examined differences associated with visits to the emergency department. Methods: We conducted a 6-year population-based cohort analysis using administrative databases of visits (n = 30 656) by children aged less than 18 years (n = 20 956) in Alberta. We measured differences in the number of visits by socioeconomic and First Nations status using directly standardized rates. We examined time to return to the emergency department using a Cox regression model, and we evaluated time to follow-up with a physician by physician type using a competing risks model. Results: First Nations children aged 15–17 years had the highest rate of visits for girls (7047 per 100 000 children) and boys (5787 per 100 000 children); children in the same age group from families not receiving government subsidy had the lowest rates (girls: 2155 per 100 000 children; boys: 1323 per 100 000 children). First Nations children (hazard ratio [HR] 1.64; 95% confidence interval [CI] 1.30–2.05), and children from families receiving government subsidies (HR 1.60, 95% CI 1.30–1.98) had a higher risk of return to an emergency department for mental health care than other children. The longest median time to follow-up with a physician was among First Nations children (79 d; 95% CI 60–91 d); this status predicted longer time to a psychiatrist (HR 0.47, 95% CI 0.32–0.70). Age, sex, diagnosis and clinical acuity also explained post-crisis use of health care. Interpretation: More visits to the emergency department for mental health crises were made by First Nations children and children from families receiving a subsidy. Sociodemographics predicted risk of return to the emergency department and follow-up care with a physician.

Evaluation of an online discussion forum for emergency practitioners

Knowledge is a critical element in the delivery of quality healthcare. In a busy emergency department (ED) clinicians attempting clinically relevant discussion with their peers face multiple interruptions and a lack of sustained meaningful interactions. Information and communication technologies such as online discussion forums enable practitioners to share practice knowledge at times that fit into their daily workflow. We conducted an experiment in which we provided emergency clinicians with access to an asynchronous discussion forum as a medium to support development of an online social network for information exchange. The outcomes were evaluated using a social network perspective to better understand the knowledge seeking and sharing behaviors among rural and urban emergency practitioners participating in the online discussion forum. The online discussion forum created an opportunity for emergency practitioners from multiple ED sites to engage in dialogue around topics that were relevant to their practice learning needs.
