Making sense of implementation theories, models and frameworks

BackgroundImplementation science has progressed towards increased use of theoretical approaches to provide better understanding and explanation of how and why implementation succeeds or fails. The aim of this article is to propose a taxonomy that distinguishes between different categories of theories, models and frameworks in implementation science, to facilitate appropriate selection and application of relevant approaches in implementation research and practice and to foster cross-disciplinary dialogue among implementation researchers.DiscussionTheoretical approaches used in implementation science have three overarching aims: describing and/or guiding the process of translating research into practice (process models); understanding and/or explaining what influences implementation outcomes (determinant frameworks, classic theories, implementation theories); and evaluating implementation (evaluation frameworks).SummaryThis article proposes five categories of theoretical approaches to achieve three overarching aims. These categories are not always recognized as separate types of approaches in the literature. While there is overlap between some of the theories, models and frameworks, awareness of the differences is important to facilitate the selection of relevant approaches. Most determinant frameworks provide limited “how-to” support for carrying out implementation endeavours since the determinants usually are too generic to provide sufficient detail for guiding an implementation process. And while the relevance of addressing barriers and enablers to translating research into practice is mentioned in many process models, these models do not identify or systematically structure specific determinants associated with implementation success. Furthermore, process models recognize a temporal sequence of implementation endeavours, whereas determinant frameworks do not explicitly take a process perspective of implementation.

Effectiveness of strategies to implement brief alcohol intervention in primary healthcare. A systematic review.

Objective. To review systematically the available literature on implementation of brief alcohol interventions in primary healthcare in order to determine the effectiveness of the implementation efforts by the health are providers. Key question. To what extent have the efforts to implement brief alcohol interventions in primary healthcare environments been successful? Method. Literature search from Medline, Cinahl, PsychLIT, Cochrane. Setting. Primary healthcare. Material. A total of 11 studies encompassing 921 GPs, 266 nurses, 88 medical students, and 44 “non-physicians” from Europe, the USA, and Australia. Main outcome measures. Material utilization, screening, and brief intervention rates. Answer. Intervention effectiveness (material utilization, screening, and brief intervention rates) generally increased with the intensity of the intervention effort, i.e. the amount of training and/or support provided. Nevertheless, the overall effectiveness was rather modest. However, the studies examined were too heterogeneous, not scientifically rigorous enough, and applied too brief follow-up times to provide conclusive answers.

Predictors of Drinking During Pregnancy: A Systematic Review

BACKGROUND Many pregnant women continue to drink alcohol despite clinical recommendations and public health campaigns about the risks associated with alcohol use during pregnancy. This review examines the predictors of prenatal alcohol use, with the long-term goal of developing more effective preventive efforts. METHODS A literature search of several databases for relevant articles was undertaken. Studies were included if they occurred in the context of antenatal care, collected data during the womans pregnancy (between 1999 and 2009), investigated predictors of any drinking, had a population-based orientation (e.g., did not focus only on high-risk drinkers), and were published in English in a scientific peer-reviewed journal between 1999 and 2009. RESULTS Fourteen studies published between 2002 and 2009 fulfilled the inclusion criteria (United States, 4; Europe, 4; Australia and New Zealand, 3; Japan, 2; and Uganda, 1). The predictors of prenatal alcohol use most consistently identified were prepregnancy alcohol consumption and having been abused or exposed to violence. Less consistent predictors of drinking during pregnancy were high income/social class and positive dependence screen. Unemployment, marital status, and education level were examined in many studies but found to be predictive only infrequently. CONCLUSIONS Womens prepregnancy alcohol consumption (i.e., quantity and frequency of typical drinking) and exposure to abuse or violence were consistently associated with drinking during pregnancy. Antenatal care providers should assess these factors for improved detection of women at risk for alcohol-exposed pregnancies.

Creatures of habit: accounting for the role of habit in implementation research on clinical behaviour change

BackgroundSocial cognitive theories on behaviour change are increasingly being used to understand and predict healthcare professionals’ intentions and clinical behaviours. Although these theories offer important insights into how new behaviours are initiated, they provide an incomplete account of how changes in clinical practice occur by failing to consider the role of cue-contingent habits. This article contributes to better understanding of the role of habits in clinical practice and how improved effectiveness of behavioural strategies in implementation research might be achieved.DiscussionHabit is behaviour that has been repeated until it has become more or less automatic, enacted without purposeful thinking, largely without any sense of awareness. The process of forming habits occurs through a gradual shift in cognitive control from intentional to automatic processes. As behaviour is repeated in the same context, the control of behaviour gradually shifts from being internally guided (e.g., beliefs, attitudes, and intention) to being triggered by situational or contextual cues. Much clinical practice occurs in stable healthcare contexts and can be assumed to be habitual. Empirical findings in various fields suggest that behaviours that are repeated in constant contexts are difficult to change. Hence, interventions that focus on changing the context that maintains those habits have a greater probability of success. Some sort of contextual disturbance provides a window of opportunity in which a behaviour is more likely to be deliberately considered. Forming desired habits requires behaviour to be carried out repeatedly in the presence of the same contextual cues.SummarySocial cognitive theories provide insight into how humans analytically process information and carefully plan actions, but their utility is more limited when it comes to explaining repeated behaviours that do not require such an ongoing contemplative decisional process. However, despite a growing interest in applying behavioural theory in interventions to change clinical practice, the potential importance of habit has not been explored in implementation research.

Key factors influencing adoption of an innovation in primary health care: a qualitative study based on implementation theory

BackgroundBridging the knowledge-to-practice gap in health care is an important issue that has gained interest in recent years. Implementing new methods, guidelines or tools into routine care, however, is a slow and unpredictable process, and the factors that play a role in the change process are not yet fully understood. There is a number of theories concerned with factors predicting successful implementation in various settings, however, this issue is insufficiently studied in primary health care (PHC). The objective of this article was to apply implementation theory to identify key factors influencing the adoption of an innovation being introduced in PHC in Sweden.MethodsA qualitative study was carried out with staff at six PHC units in Sweden where a computer-based test for lifestyle intervention had been implemented. Two different implementation strategies, implicit or explicit, were used. Sixteen focus group interviews and two individual interviews were performed. In the analysis a theoretical framework based on studies of implementation in health service organizations, was applied to identify key factors influencing adoption.ResultsThe theoretical framework proved to be relevant for studies in PHC. Adoption was positively influenced by positive expectations at the unit, perceptions of the innovation being compatible with existing routines and perceived advantages. An explicit implementation strategy and positive opinions on change and innovation were also associated with adoption. Organizational changes and staff shortages coinciding with implementation seemed to be obstacles for the adoption process.ConclusionWhen implementation theory obtained from studies in other areas was applied in PHC it proved to be relevant for this particular setting. Based on our results, factors to be taken into account in the planning of the implementation of a new tool in PHC should include assessment of staff expectations, assessment of the perceived need for the innovation to be implemented, and of its potential compatibility with existing routines. Regarding context, we suggest that implementation concurrent with other major organizational changes should be avoided. The choice of implementation strategy should be given thorough consideration.

Never the twain shall meet? - a comparison of implementation science and policy implementation research

BackgroundMany of society’s health problems require research-based knowledge acted on by healthcare practitioners together with implementation of political measures from governmental agencies. However, there has been limited knowledge exchange between implementation science and policy implementation research, which has been conducted since the early 1970s. Based on a narrative review of selective literature on implementation science and policy implementation research, the aim of this paper is to describe the characteristics of policy implementation research, analyze key similarities and differences between this field and implementation science, and discuss how knowledge assembled in policy implementation research could inform implementation science.DiscussionFollowing a brief overview of policy implementation research, several aspects of the two fields were described and compared: the purpose and origins of the research; the characteristics of the research; the development and use of theory; determinants of change (independent variables); and the impact of implementation (dependent variables). The comparative analysis showed that there are many similarities between the two fields, yet there are also profound differences. Still, important learning may be derived from several aspects of policy implementation research, including issues related to the influence of the context of implementation and the values and norms of the implementers (the healthcare practitioners) on implementation processes. Relevant research on various associated policy topics, including The Advocacy Coalition Framework, Governance Theory, and Institutional Theory, may also contribute to improved understanding of the difficulties of implementing evidence in healthcare. Implementation science is at a relatively early stage of development, and advancement of the field would benefit from accounting for knowledge beyond the parameters of the immediate implementation science literature.SummaryThere are many common issues in policy implementation research and implementation science. Research in both fields deals with the challenges of translating intentions into desired changes. Important learning may be derived from several aspects of policy implementation research.

What makes community based injury prevention work? In search of evidence of effectiveness.

Community based injury prevention work has become a widely accepted strategy among safety promotion specialists. Hundreds of community based injury prevention programs have been implemented since the mid-1970s, but relatively few have been evaluated rigorously, resulting in a lack of consensus regarding the effectiveness of this approach. This study sought to identify key components that contribute to the effectiveness of these programs. The objective was to gain a better understanding of the community based model for injury prevention. The study was performed as a structured review of existing evaluations of injury prevention programs that employed multiple strategies to target different age groups, environments, and situations. The results of this study suggested that there are complex relationships between the outcome and the context, structure, and process of community-wide injury prevention programs. The interconnectedness of these variables made it difficult to provide solid evidence to prioritise in terms of program effectiveness. The evaluations of multifaceted community oriented injury prevention programs were found to have many shortcomings. Meagre descriptions of community characteristics and conditions, insufficient assessment of structural program components, and failure to establish process-outcome relationships contributed to the difficulty of identifying key success factors of the programs.

Does a physical activity referral scheme improve the physical activity among routine primary health care patients

Physical activity referral (PAR) schemes or concepts occur in varying forms. Because few physical activity intervention studies have been carried out in routine health care settings, it is difficult to translate research findings into daily practice. The aim of this study was to analyze the effectiveness of a PAR scheme implemented in routine primary health care. The study did not include a control group and was based on the ordinary staffs work efforts and follow‐up measures. During a 2‐year period, 6300 PARs were issued. Effectiveness was measured by an increase in self‐reported physical activity. Half of the patients reached reported increased physical activity both at 3 months (49%) and at 12 months (52%). The proportion of inactive patients decreased from 33% at baseline to 17% at 3 months and 20% at 12 months. The proportion of patients who were physically active on a regular basis increased from 22% at baseline to 33% at 3 months and 32% at 12 months. Neither the patients age nor the profession of the prescriber was associated with differences in effectiveness. The patients activity level at baseline, the type of physical activity as well as the reason for the prescription were associated with increased physical activity.

Physical activity referrals in Swedish primary health care - prescriber and patient characteristics, reasons for prescriptions, and prescribed activities.

BackgroundOver the past decade, practitioners in primary health care (PHC) settings in many countries have issued written prescriptions to patients to promote increased physical activity or exercise. The aim of this study is to describe and analyse a comprehensive physical activity referral (PAR) scheme implemented in a routine PHC setting in Östergötland County. The study examines characteristics of the PARs recipients and referral practitioners, identifies reasons why practitioners opted to use PARs with their clients, and discusses prescribed activities and prescriptions in relation to PHC registries.MethodsProspective prescription data were obtained for 90% of the primary health care centres in Östergötland County, Sweden, in 2004 and 2005. The study population consisted of patients who were issued PARs after they were deemed likely to benefit from increased physical activity, as assessed by PHC staff.ResultsDuring the two-year period, a total of 6,300 patients received PARs. Two-thirds of the patients were female and half of the patients were 45–64 years. Half of the patients (50.8%) who received PARs were recommended a home-based activity, such as walking. One third (33%) of the patients issued PARs were totally inactive, reporting no days of physical activity that lasted for 30 minutes, and 29% stated that they reached this level 1–2 days per week.The number of PARs prescribed per year in relation to the number of unique individuals that visited primary health care during one year was 1.4% in 2004 and 1.2% in 2005. Two-thirds of the combined prescriptions were issued by physicians (38%) and nurses (31%). Physiotherapists and behavioural scientists issued the highest relative number of prescriptions. The most common reasons for issuing PARs were musculoskeletal disorders (39.1%) and overweight (35.4%), followed by high blood pressure (23.3%) and diabetes (23.2%).ConclusionÖstergötland Countys PAR scheme reached a relatively high proportion of physically inactive people visiting local PHC centres for other health reasons. PAR-related statistics, including PAR-rates by individual PHC centres and PAR- rates per health professional category, show differences in prescribing activities, both by patient categories, and by prescribing professionals.

Brief interventions in routine health care: a population‐based study of conversations about alcohol in Sweden

AIMS To investigate how brief alcohol interventions are delivered in routine practice in the Swedish health-care system. DESIGN, SETTING AND PARTICIPANTS A cross-sectional sample of 6000 individuals representative of the adult population aged 18-64 years registered in the Swedish total population register was drawn randomly. Data were collected in 2010 by means of a mail questionnaire. The response rate was 54%. MEASUREMENTS The questionnaire consisted of 27 questions, of which 15 variables were extracted for use in this study. Whether alcohol had been discussed and the duration, contents, experiences and effects of any conversations about alcohol, as reported by patients themselves, were assessed. FINDINGS Sixty-six per cent of the respondents had visited health-care services in the past 12 months and 20% of these had had one or more conversations about alcohol during these visits (13% of the population aged 18-64 years). The duration of the conversations was generally brief, with 94% taking less than 5 minutes, and were not experienced as problematic. The duration, contents, experiences and effects of these conversations generally varied between abstainers, moderate, hazardous and excessive drinkers. Twelve per cent of those having a conversation about alcohol reported that it led to reduced alcohol consumption. Reduced alcohol consumption was more likely when conversations lasted for 1-10 minutes rather than less than 1 minute and included advice on how to reduce consumption. CONCLUSIONS Population survey data in Sweden suggest that when health-care professionals give brief advice to reduce alcohol consumption, greater effects are observed when the advice is longer and includes advice on how to achieve it.
