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.

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.

Feasibility of a Thermographic Method for Early Detection of Foot Disorders in Diabetes

BACKGROUND Foot complications due to diabetes impose a major economic burden to society and loss of health-related quality of life for the patients. Early diagnosis and intensified preventive measures have proved useful to limit the incidence of foot ulcers and lower limb amputations in diabetes, and the development of new tools for early diagnosis has therefore become an attractive option. This article covers a feasibility study of the SpectraSole (Linköping, Sweden) Pro 1000 foot indicator, an innovation based on liquid crystal thermography. The technology identifies increases in temperature, a known indicator of inflammation. METHODS Sixty-five patients with diagnosed diabetes were examined with the foot indicator immediately after their ordinary foot examinations according to current practice, and findings from the two investigations were compared. RESULTS Sixty-nine examinations were performed. The foot indicator identified increased temperature in 31 cases, of which six had not been detected in the preceding ordinary examinations. The instrument was perceived as easy to use, and the thermographs could be used to visualize problem areas of the foot, which might contribute to better compliance with therapeutic advice. CONCLUSIONS The foot indicator detected a relatively high share of the different types of complications but not all. It can be used as a complement to current practices for foot examination. The instrument provides rapid imaging of the foot temperature, and the study indicates that it yields valuable diagnostic information in early stages of foot disease.

Factors influencing patient safety in Sweden: perceptions of patient safety officers in the county councils

BackgroundNational, regional and local activities to improve patient safety in Sweden have increased over the last decade. There are high ambitions for improved patient safety in Sweden. This study surveyed health care professionals who held key positions in their county council’s patient safety work to investigate their perceptions of the conditions for this work, factors they believe have been most important in reaching the current level of patient safety and factors they believe would be most important for achieving improved patient safety in the future.MethodsThe study population consisted of 218 health care professionals holding strategic positions in patient safety work in Swedish county councils. Using a questionnaire, the following topics were analysed in this study: profession/occupation; number of years involved in a designated task on patient safety issues; knowledge/overview of the county council’s patient safety work; ability to influence this work; conditions for this work; and the importance of various factors for current and future levels of patient safety.ResultsThe response rate to the questionnaire was 79%. The conditions that had the highest number of responses in complete agreement were “patients’ involvement is important for patient safety” and “patient safety work has good support from the county council’s management”. Factors that were considered most important for achieving the current level of patient safety were root cause and risk analyses, incident reporting and the Swedish Patient Safety Law. An organizational culture that encourages reporting and avoids blame was considered most important for improved patient safety in the future, closely followed by improved communication between health care practitioners and patients.ConclusionHealth care professionals with important positions in the Swedish county councils’ patient safety work believe that conditions for this work are somewhat constrained. They attribute the current levels of patient safety to a broad range of factors and believe that many different solutions can contribute to enhanced patient safety in the future, suggesting that this work must be multifactorial.

Factors influencing rheumatologists’ prescription of biological treatment in rheumatoid arthritis: an interview study

BackgroundThe introduction of biological drugs involved a fundamental change in the treatment of rheumatoid arthritis (RA). The extent to which biological drugs are prescribed to RA patients in different regions in Sweden varies greatly. Previous research has indicated that differences in health care practice at the regional level might obscure differences at the individual level. The objective of this study is to explore what influences individual rheumatologists’ decisions when prescribing biological drugs.MethodSemi-structured interviews, utilizing closed- and open-ended questions, were conducted with senior rheumatologists, selected through a mix of random and purposive sampling. The interview questions consisted of two parts, with a “parallel mixed method” approach. In the first and main part, open-ended exploratory questions were posed about factors influencing prescription. In the second part, the rheumatologists were asked to rate predefined factors that might influence their prescription decisions. The Consolidated Framework for Implementation Research (CFIR) was used as a conceptual framework for data collection and analysis.ResultsTwenty-six rheumatologists were interviewed. A constellation of various factors and their interaction influenced rheumatologists’ prescribing decisions, including the individual rheumatologists experiences and perceptions of the evidence, the structure of the department including responsibility for costs, peer pressure, political and administrative influences, and participation in clinical trials. The patient as an actor emerged as an important factor. Hence, factors both at organizational and individual levels influenced the prescribing of biological drugs. The factors should not be seen as individual influences but were described as influencing prescription in an interactive, nonlinear way.ConclusionsPotential factors explaining differences in prescription practice are experience and perception of the evidence on the individual level and the structure of the department and participation in clinical trials on the organizational level. The influence of patient attitudes and preferences and interpretation of scientific evidence seemed to be somewhat contradictory in the qualitative responses as compared to the quantitative rating, and this needs further exploration. An implication of the present study is that in addition to scientific knowledge, attempts to influence prescription behavior need to be multifactorial and account for interactions of factors between different actors.

Facilitators and barriers influencing patient safety in Swedish hospitals: a qualitative study of nurses’ perceptions

BackgroundSweden has undertaken many national, regional, and local initiatives to improve patient safety since the mid-2000s, but solid evidence of effectiveness for many solutions is often lacking. Nurses play a vital role in patient safety, constituting 71% of the workforce in Swedish health care. This interview study aimed to explore perceived facilitators and barriers influencing patient safety among nurses involved in the direct provision of care. Considering the importance of nurses with regard to patient safety, this knowledge could facilitate the development and implementation of better solutions.MethodsA qualitative study with semi-structured individual interviews was carried out. The study population consisted of 12 registered nurses at general hospitals in Sweden. Data were analyzed using qualitative content analysis.ResultsThe nurses identified 22 factors that influenced patient safety within seven categories: ‘patient factors’, ‘individual staff factors’, ‘team factors’, ‘task and technology factors’, ‘work environment factors’, ‘organizational and management factors’, and ‘institutional context factors’. Twelve of the 22 factors functioned as both facilitators and barriers, six factors were perceived only as barriers, and four only as facilitators. There were no specific patterns showing that barriers or facilitators were more common in any category.ConclusionA broad range of factors are important for patient safety according to registered nurses working in general hospitals in Sweden. The nurses identified facilitators and barriers to improved patient safety at multiple system levels, indicating that complex multifaceted initiatives are required to address patient safety issues. This study encourages further research to achieve a more explicit understanding of the problems and solutions to patient safety.

Physician Preferences and Variations in Prescription of Biologic Drugs for Rheumatoid Arthritis: A Register-Based Study of 4,010 Patients in Sweden.

The prescription of biologic drugs for rheumatoid arthritis (RA) patients has varied considerably across different regions. Previous studies have shown physician preferences to be an important determinant in the decision to select biologic disease‐modifying antirheumatic drugs (bDMARDs) rather than nonbiologic, synthetic DMARDs (sDMARDs) alone. The aim of this study was to test the hypothesis that physician preferences are an important determinant for prescribing bDMARDs for RA patients in Sweden.

Five years’ experience of an annual course on implementation science: an evaluation among course participants

BackgroundIncreasing interest in implementation science has generated a demand for education and training opportunities for researchers and practitioners in the field. However, few implementation science courses have been described or evaluated in the scientific literature. The aim of the present study was to provide a short- and long-term evaluation of the implementation training at Linköping University, Sweden.MethodsTwo data collections were carried out. In connection with the final seminar, a course evaluation form, including six items on satisfaction and suggestions for improvement, was distributed to the course participants, a total of 101 students from 2011 to 2015 (data collection 1), response rate 72%. A questionnaire including six items was distributed by e-mail to the same students in autumn 2016 (data collection 2), response rate 63%. Data from the two data collections were presented descriptively and analysed using the Kirkpatrick model consisting of four levels: reaction, learning, behaviour and results.ResultsThe students were very positive immediately after course participation, rating high on overall perception of the course and the contents (reaction). The students also rated high on achievement of the course objectives and considered their knowledge in implementation science to be very good and to a high degree due to course participation (learning). Knowledge gained from the course was viewed to be useful (behaviour) and was applied to a considerable extent in research projects and work apart from research activities (results).ConclusionsThe evaluation of the doctoral-level implementation science course provided by Linköping University showed favourable results, both in the short and long term. The adapted version of the Kirkpatrick model was useful because it provided a structure for evaluation of the short- and long-term learning outcomes.

The impact of service and hearing dogs on health-related quality of life and activity level: a Swedish longitudinal intervention study

BackgroundIndividuals with severe disability often require personal assistance and help from informal caregivers, in addition to conventional health care. The utilization of assistance dogs may decrease the need for health and social care and increase the independence of these individuals. Service and hearing dogs are trained to assist specific individuals and can be specialized to meet individual needs. The aim of this study was to describe and explore potential consequences for health-related quality of life, well-being and activity level, of having a certified service or hearing dog.MethodsA longitudinal interventional study with a pre-post design was conducted. At inclusion, all participants in the study had a regular (untrained) companion dog. Data were collected before training of the dog started and three months after certification of the dog. Health-related quality of life was assessed with EQ-5D-3L, EQ-VAS and RAND-36. Well-being was measured with WHO-5 and self-esteem with the Rosenberg Self-Esteem Scale. In addition, questions were asked about physical activity and time spent away from home and on social activities. Subgroups were analyzed for physical service and diabetes alert dogs.ResultsFifty-five owner-and-dog pairs completed the study (30 physical service dogs, 20 diabetes alert dogs, 2 epilepsy alert dogs, and 3 hearing dogs). Initially, study participants reported low health-related quality of life compared with the general population. At follow-up, health-related quality of life measured with the EQ-VAS, well-being and level of physical activity had improved significantly. In the subgroup analysis, physical service dog owners had lower health-related quality of life than diabetes alert dog owners. The improvement from baseline to follow-up measured with EQ-5D statistically differed between the subgroups.ConclusionsThe target population for service and hearing dogs has an overall low health-related quality of life. Our study indicates that having a certified service or hearing dog may have positive impact on health-related quality of life, well-being and activity level. Service and hearing dogs are a potentially important “wagging tail aid” for this vulnerable population, able to alleviate strain, increase independence, and decrease the risk of social isolation.Trial RegistrationThe trial was retrospectively registered in http://clinicaltrial.gov, NCT03270592.

Individual variations in treatment decisions by Swedish rheumatologists regarding biological drugs for rheumatoid arthritis

Objectives: In Sweden, reports indicate surprisingly large regional variation in prescription of biological drugs despite a growing number of clinical studies describing their beneficial effects and guidelines by professional organizations and agencies. Our objectives were to ascertain whether there is also variation between individual rheumatologists in prescribing biologics to patients with rheumatoid arthritis (RA) and to evaluate reasons for treatment choices. Method: Ten hypothetical patient cases were constructed and presented to 26 rheumatologists in five regions in Sweden. The cases were based on actual cases and were thoroughly elaborated by a senior rheumatologist and pre-tested in a pilot study. The respondents were asked whether they would treat the patients with a biological agent (Yes/No) and to explain their decisions. Results: The response rate was 26/105 (25%). Treatment choices varied considerably between the rheumatologists, some prescribing biologics to 9/10 patients and others to 2/10. In five of the 10 hypothetical cases, approximately half of the respondents would prescribe biologics. No regions with particularly high or low prescription were identified. Both the decisions to prescribe biologics and also not to prescribe biologics were mainly motivated by medical reasons. Some rheumatologists also referred to lifestyle-related factors or the social function of the patient. Conclusions: The choice of initiation of biologics varied substantially among rheumatologists presented with hypothetical patient cases, and there were also disparities between rheumatologists practicing at the same clinic. Treatment choices were motivated primarily by medical reasons. This situation raises concerns about a lack of consensus in RA treatment strategies.
