Fostering implementation of health services research findings into practice: a consolidated framework for advancing implementation science

Abstract Background Many interventions found to be effective in health services research studies fail to translate into meaningful patient care outcomes across multiple contexts. Health services researchers recognize the need to evaluate not only summative outcomes but also formative outcomes to assess the extent to which implementation is effective in a specific setting, prolongs sustainability, and promotes dissemination into other settings. Many implementation theories have been published to help promote effective implementation. However, they overlap considerably in the constructs included in individual theories, and a comparison of theories reveals that each is missing important constructs included in other theories. In addition, terminology and definitions are not consistent across theories. We describe the Consolidated Framework For Implementation Research (CFIR) that offers an overarching typology to promote implementation theory development and verification about what works where and why across multiple contexts. Methods We used a snowball sampling approach to identify published theories that were evaluated to identify constructs based on strength of conceptual or empirical support for influence on implementation, consistency in definitions, alignment with our own findings, and potential for measurement. We combined constructs across published theories that had different labels but were redundant or overlapping in definition, and we parsed apart constructs that conflated underlying concepts. Results The CFIR is composed of five major domains: intervention characteristics, outer setting, inner setting, characteristics of the individuals involved, and the process of implementation. Eight constructs were identified related to the intervention (e.g., evidence strength and quality), four constructs were identified related to outer setting (e.g., patient needs and resources), 12 constructs were identified related to inner setting (e.g., culture, leadership engagement), five constructs were identified related to individual characteristics, and eight constructs were identified related to process (e.g., plan, evaluate, and reflect). We present explicit definitions for each construct. Conclusion The CFIR provides a pragmatic structure for approaching complex, interacting, multi-level, and transient states of constructs in the real world by embracing, consolidating, and unifying key constructs from published implementation theories. It can be used to guide formative evaluations and build the implementation knowledge base across multiple studies and settings.http://deepblue.lib.umich.edu/bitstream/2027.42/78272/1/1748-5908-4-50.xmlhttp://deepblue.lib.umich.edu/bitstream/2027.42/78272/2/1748-5908-4-50-S1.PDFhttp://deepblue.lib.umich.edu/bitstream/2027.42/78272/3/1748-5908-4-50-S3.PDFhttp://deepblue.lib.umich.edu/bitstream/2027.42/78272/4/1748-5908-4-50-S4.PDFhttp://deepblue.lib.umich.edu/bitstream/2027.42/78272/5/1748-5908-4-50.pdfhttp://deepblue.lib.umich.edu/bitstream/2027.42/78272/6/1748-5908-4-50-S2.PDFPeer Reviewe

A preliminary investigation to explore the cognitive resources of physicians experiencing difficulty in training

Background Treating patients is complex, and research shows that there are differences in cognitive resources between physicians who experience difficulties, and those who do not. It is possible that differences in some cognitive resources could explain the difficulties faced by some physicians. In this study, we explore differences in cognitive resources between different groups of physicians (that is, between native (UK) physicians and International Medical Graduates (IMG); those who continue with training versus those who were subsequently removed from the training programme); and also between physicians experiencing difficulties compared with the general population. Methods A secondary evaluation was conducted on an anonymised dataset provided by the East Midlands Professional Support Unit (PSU). One hundred and twenty one postgraduate trainee physicians took part in an Educational Psychology assessment through PSU. Referrals to the PSU were mainly on the basis of problems with exam progression and difficulties in communication skills, organisation and confidence. Cognitive resources were assessed using the Wechsler Adult Intelligence Scale (WAIS-IV). Physicians were categorised into three PSU outcomes: ‘Continued in training’, ‘Removed from training’ and ‘Active’ (currently accessing the PSU). Results Using a one-sample Z test, we compared the referred physician sample to a UK general population sample on the WAIS-IV and found the referred sample significantly higher in Verbal Comprehension (VCI; z = 8.78) and significantly lower in Working Memory (WMI; z = −4.59). In addition, the native sample were significantly higher in Verbal Comprehension than the UK general population sample (VCI; native physicians: z = 9.95, p < .001, d = 1.25), whilst there was a lesser effect for the difference between the IMG sample and the UK general population (z = 2.13, p = .03, d = 0.29). Findings also showed a significant difference in VCI scores between those physicians who were ‘Removed from training’ and those who ‘Continued in training’. Conclusions Our results suggest it is important to understand the cognitive resources of physicians to provide a more focussed explanation of those who experience difficulties in training. This will help to implement more targeted interventions to help physicians develop compensatory strategies

Demographic, clinical and antibody characteristics of patients with digital ulcers in systemic sclerosis: data from the DUO Registry

OBJECTIVES: The Digital Ulcers Outcome (DUO) Registry was designed to describe the clinical and antibody characteristics, disease course and outcomes of patients with digital ulcers associated with systemic sclerosis (SSc). METHODS: The DUO Registry is a European, prospective, multicentre, observational, registry of SSc patients with ongoing digital ulcer disease, irrespective of treatment regimen. Data collected included demographics, SSc duration, SSc subset, internal organ manifestations, autoantibodies, previous and ongoing interventions and complications related to digital ulcers. RESULTS: Up to 19 November 2010 a total of 2439 patients had enrolled into the registry. Most were classified as either limited cutaneous SSc (lcSSc; 52.2%) or diffuse cutaneous SSc (dcSSc; 36.9%). Digital ulcers developed earlier in patients with dcSSc compared with lcSSc. Almost all patients (95.7%) tested positive for antinuclear antibodies, 45.2% for anti-scleroderma-70 and 43.6% for anticentromere antibodies (ACA). The first digital ulcer in the anti-scleroderma-70-positive patient cohort occurred approximately 5 years earlier than the ACA-positive patient group. CONCLUSIONS: This study provides data from a large cohort of SSc patients with a history of digital ulcers. The early occurrence and high frequency of digital ulcer complications are especially seen in patients with dcSSc and/or anti-scleroderma-70 antibodies

The role of carbonic anhydrase inhibitors in the management of macular edema

Medical treatment of cystoid macular edema (CME) with carbonic anhydrase inhibitors has been known for over a decade. Initial observations were based on experimental data which suggested that acetazolamide can increase fluid absorption across the retinal pigment epithelium. Carbonic anhydrase inhibitors (CAI) have also been shown to have other direct effects both on retinal and retinal pigment epithelial cell function by inducing an acidification of the subretinal space, a decrease of the standing potential as well as an increase in retinal adhesiveness. It is thought that acidification of the subretinal space is finally responsible for the increase in fluid resorption from the retina through the RPE into the choroid. Several clinical studies have suggested that patients with cystoid macular edema due to retinitis pigmentosa and uveitis may react more favorably to CAI treatment than other etiologies such as diabetic maculopathy or macular edema after retinal vein occlusion. The present working hypothesis is that diffuse leakage from the RPE responds more readily to CAI treatment than leakage from retinal vessels. This may be due to the modulation of membrane- bound CA IV in the RPE which may have lost its polarised distribution in the presence of macular edema. A normal clinical starting dose of CAI is 500 mg/day which should be continued for at least one month to see an effect. This dose may be reduced by the patients over the course of therapy. Metaphylaxis to the drug may occur with a rebound of the edema despite continuation of treatment

Process-oriented evaluation of an international faculty development program for Asian developing countries: a qualitative study

Abstract Background Non-English-speaking developing countries in Southeast Asia have been provided only limited opportunities for faculty development in the education of health professions. Although there exist a few programs that have been shown to be effective, they are frequently presented with few explanations on how and why the programs work due to their outcome-oriented nature. This study explores the process of the Lee Jong-Wook Fellowship for Health Professional Education, an international faculty development program designed for capacity building of educators of health professions in Southeast Asian developing countries. Methods Fellows were from Cambodia, Myanmar, and Laos. Qualitative data were collected from two types of semi-structured interviews – group and individual. Thematic analysis was conducted to explore the factors related to the effectiveness of the program, framed by four components of faculty development, which included context, facilitators, program, and participants. Results From the thematic analysis, the authors identified a total of 12 themes in the four components of faculty development. In the context domain, the resource-poor setting, a culture that puts emphasis on hierarchy and seniority, and educational environment depending on individual commitment rather than broad consensus emerged as key factors. In the facilitators domain, their teaching methods and materials, mutual understanding between teacher and learner, and collaboration between facilitators mainly influenced the learning during the fellowship. In the program domain, the key advantages of the fellowship program were its applicability to the workplace of the fellows and enough allowed time for practice and reflection. Finally, in the participants domain, Fellows valued their heterogeneity of composition and recognized cognitive as well as non-cognitive attributes of the participants as essential. Conclusions This process-oriented evaluation reveals the diverse factors that contributed to achieving the intended outcomes of the fellowship. Although much evidence from best practices in faculty development are still valid, the findings suggest that the selection strategies, learning environment, and English communication should be given more consideration when organizing a program targeting these people and cultures. A comprehensive understanding of the process would contribute to developing tailored strategies for educators of health professions in developing countries in similar settings
