The relationship between organizational culture and implementation of clinical practice guidelines: a narrative review

The context in which critical care providers work has been shown to be associated with adherence to recommendations of clinical practice guidelines (CPGs). Consideration of contextual factors such as organizational culture may therefore be important when implementing guidelines. Organizational culture has been defined simply as "how things are around here" and encompasses leadership, communication, teamwork, conflict resolution, and other domains. This narrative review highlights the results of recent quantitative and qualitative studies, including studies on adherence to nutrition guidelines in the critical care setting, which demonstrate that elements of organizational culture, such as leadership support, interprofessional collaboration, and shared beliefs about the utility of guidelines, influence adherence to guideline recommendations. Outside nutrition therapy, there is emerging evidence that strategies focusing on organizational change (eg, revision of professional roles, interdisciplinary teams, integrated care delivery, computer systems, and continuous quality improvement) can favorably influence professional performance and patient outcomes. Consequently, future interventions aimed at implementing nutrition guidelines should aim to measure and take into account organizational culture, in addition to considering the characteristics of the patient, provider, and guideline. Further high quality, multimethod studies are required to improve our understanding of how culture influences guideline implementation, and which organizational change strategies might be most effective in optimizing nutrition therapy.     

Lost in (knowledge) translation!

Critical care nutrition guidelines have been developed to help busy practitioners decide how to feed their critically ill patients. However, despite the publication of guidelines and efforts to disseminate and implement them, there are large gaps between what the recommendations say and what is happening at the bedside. Consequently, the nutrition therapy received by many patients remains suboptimal. Knowledge translation is a term increasingly used in healthcare to describe the process of moving evidence learned from clinical research and summarized in clinical practice guidelines to incorporation into clinical and policy decision making. In this article, knowledge about the implementation of critical care nutrition guidelines is applied to Graham et al's knowledge-to-action model to illuminate the issues pertinent to knowledge translation in critical care nutrition. This model has 2 components: knowledge creation and action. The action component consists of 8 phases of the action cycle that represent activities needed to move knowledge into practice and are derived from planned-action theory. Components of this model are illustrated via empirically derived research, commentaries, and published studies from the field of critical care nutrition. It is hoped that this article and related articles in this issue of JPEN will help critical care nutrition practitioners to better understand the often complex and convoluted road of translating knowledge into practice so that as a community we are no longer "lost" but have direction that can bring about positive changes in nutrition practice.     

The Methodological Quality of Economic Evaluations of Guideline Implementation into Clinical Practice: A Systematic Review of Empiric Studies

OBJECTIVES: Despite the emphasis on efficiency of health-care services delivery, there is an imperfect evidence base to inform decisions about whether and how to develop and implement guidelines into clinical practice. In general, studies evaluating the economics of guideline implementation lack methodological rigor. We conducted a systematic review of empiric studies to assess advances in the economic evaluations of guideline implementation. METHODS: The Cochrane Effective Professional and Organisational Change Group specialized register and the MEDLINE database were searched for English publications between January 1998 and July 2004 that reported objective effect measures and implementation costs. We extracted data on study characteristics, quality of study design, and economic methodology. It was assessed whether the economic evaluations followed methodological guidance. RESULTS: We included 24 economic evaluations, involving 21 controlled trials and three interrupted time series designs. The studies involved varying settings, targeted professionals, targeted behaviors, clinical guidelines, and implementation strategies. Overall, it was difficult to determine the quality of study designs owing to poor reporting. In addition, most economic evaluations were methodologically flawed: studies did not follow guidelines for evaluation design, data collection, and data analysis. CONCLUSIONS: The increasing importance of the value for money of providing health care seems to be reflected by an increase in empiric economic evaluations of guideline implementation. Because of the heterogeneity and poor methodological quality of these studies, however, the resulting evidence is still of limited use in decision-making. There seems to be a need for more methodological guidance, especially in terms of data collection and data synthesis, to appropriately evaluate the economics of developing and implementing guidelines into clinical practice.     

Nutritional management of cystic fibrosis in Australia and New Zealand

Aim:  To document current practice in the nutritional management of cystic fibrosis in Australia and New Zealand and to examine changes in practice since 1996.
Methods:  Thirty-four cystic fibrosis services in Australia and New Zealand responded to a survey that examined current nutritional management practices and dietetic staffing levels. The questionnaire was based on a previous survey conducted in 1996.
Results:  Cystic fibrosis dietetic staffing levels were low. No service met the staffing level recommended by the UK Cystic Fibrosis Trust. Minor practice variations existed in nutrition assessment and monitoring: nutrition support and vitamin supplementation. Changes in the management of pancreatic enzyme replacement therapy and cystic fibrosis-related diabetes were reported since 1996.
Conclusion:  This survey highlights that improvements in consistency of nutrition management have been achieved since 1996 and reflect adherence to available clinical guidelines for pancreatic enzyme replacement therapy. While there are many areas of agreement in nutrition care for people with cystic fibrosis around Australia and New Zealand, there are still practice differences, implying that Australian- and New Zealand-specific clinical guidelines are warranted. The implementation of the Australasian Clinical Practice Guidelines for Nutrition in Cystic Fibrosis will be important in standardising and improving cystic fibrosis care.     

International Consensus Guidelines for Nutrition Therapy in Pancreatitis

Guidelines for nutrition support in pancreatitis have been inconsistently adapted to clinical practice. The International Consensus Guideline Committee (ICGC) established a pancreatitis task force to review published guidelines for pancreatitis in nutrition support. A PubMed search using the terms pancreatitis, acute pancreatitis, chronic pancreatitis, nutrition support, parenteral nutrition, enteral nutrition, and guidelines was conducted for the period from January 1999 to May 2011. Eleven guidelines were identified for review. The ICGC used the following process to develop unified guideline statements: summarize the strength of evidence (grading) of the guidelines; establish level of evidence for ICGC statements as high, intermediate, and low; assign published guideline levels of evidence; and define an ICGC grading system. International Pancreatitis Guideline Grades were established as follows: platinum—high level of evidence and consistent agreement among the guidelines; gold—acceptable level of evidence and no conflicting statements in guidelines; and silver—single existing guideline statement with no conflict in other guidelines. Eighteen ICGC statements were derived from the 11 published pancreatitis guidelines. Uniform agreement from widely disparate groups (United States, Europe, Japan, and China) resulted in 4 platinum‐level guideline statements for nutrition in pancreatitis: nutrition support therapy (NST) is generally not needed for mild to moderate disease, NST is needed for severe disease, enteral nutrition (EN) is preferred over parenteral nutrition (PN), and use PN when EN is contraindicated or not feasible. This methodology provides a template for future ICGC nutrition guideline development.     

Nutrition beyond drugs and devices: a review of the approaches to enhance the capacity of nutrition care provision by general practitioners

The prevention and management of chronic disease is a key priority for primary care services. Nutrition-related care is an integral feature of several best practice guidelines for management of chronic disease in the general practice setting. This paper critically reviews the international literature to enhance the nutrition knowledge, skills and overall capacity of GPs to provide nutrition care using examples from nutrition in medical education, continuing medical education, GP-centred and practice-setting approaches. The medical nutrition education approach provides an opportunity for linear translation between desired nutrition competencies and curriculum learning objectives, while that of continuing medical education allows for tailored nutrition education to increase nutrition competencies once a learning need is identified. The GP-centred approach focuses on the determinants of nutrition care provision by GPs as strategies for enhancing nutrition care delivery, whereas the practice setting approach aims to increase the nutrition-related exposure to patients through avenues independent of the GP. In the Australian and New Zealand context, the potential appropriateness of these approaches requires judicious consideration, as it is unlikely that one approach will comprehensively address this topic. Ongoing multifaceted evaluation of each approach is needed to ensure enhancement of GPs' capacity to provide nutrition care by increasing nutrition knowledge and skills, and improving patient health outcomes.     

Dietetic practice in the management of gestational diabetes mellitus: A survey of Australian dietitians

Aim: To examine current Australian dietetic practice in the management of gestational diabetes, to identify models of dietetic care and to determine the need for national evidence‐based dietetic practice guidelines for gestational diabetes. Methods: A 55‐item cross‐sectional survey of Australian dietitians practicing in the area of gestational diabetes was undertaken. Participants were recruited via Dietitians Association of Australia interest group membership, public and private hospital maternity and diabetes services across Australia. The survey examined dietetic service provision, interventions, management recommendations, postnatal care, current guideline use and the perceived need for Australian evidence‐based dietetic management guidelines. Results: A total of 220 eligible dietitians participated in the survey. The majority (77%) reported that all women with gestational diabetes attending their service were referred to a dietitian. Group (33%) and individual consults (93%) were provided and 67% provided one to two dietetic consults per client. Fifty‐four per cent (54%) believed that their service currently offered adequate antenatal dietetic interventions and 8% adequate postnatal follow up for women with gestational diabetes. There were differences in the implementation of medical nutrition therapy by Australian dietitians in regards to nutrient recommendations. However, consistency was seen in key components of nutrition education. Dietitians perceived that there was a need for evidence‐based gestational diabetes dietetic practice guidelines (86%) and nutrition recommendations (87%). Conclusion: The survey results strongly indicate there is a need for evidence‐based gestational diabetes practice guidelines and nutritional recommendations and provide baseline data for future practice of Australian dietitians working in gestational diabetes.     

Systematic review of economic evaluations and cost analyses of guideline implementation strategies

To appraise the quality of economic studies undertaken as part of evaluations of guideline implementation strategies, we conducted a systematic review of such studies published between 1966 and 1998. Studies were assessed against BMJ economic evaluations guidelines for each stage (guideline development, implementation and treatment). Of 235 studies identified, 63 reported some information on cost. Only 3 studies provided evidence that their guideline was effective and efficient, 38 reported treatment costs only, 12 implementation and treatment costs, 11 implementation costs alone, and 2 guideline development, implementation and treatment costs. No study gave reasonably complete information on costs. Thus, very few satisfactory economic evaluations of guideline implementation strategies have been performed. Current evaluations have numerous methodological defects and rarely consider all relevant costs and benefits. Future evaluations should focus on evaluating the implementation of evidence-based guidelines. Additional data for tables are available on request from the authors.     

Developing Clinical Practice Guidelines

Clinical practice guidelines have gradually become a normal part of daily life for many clinicians. In order to provide good support for practitioners and patients in their decisions on appropriate care, the practice guidelines should be of high quality, i. e. developed by a credible organisation, based on the best available scientific evidence, tested for applicability, implemented through multiple strategies, and their use and impact continuously monitored.Many of the guideline development programmes in Europe do not meet these criteria. Guideline-setting initiatives in seven European countries are presented in this review. Of these, three specific programmes are described in detail: one that is mainly professionally driven (The Netherlands), one that is primarily academically driven (UK), and one that is mainly based on initiatives by the authorities (France).Large intercountry differences are evident in guideline setting initiatives. These differences include the nature of the guidelines, their aims, the methods used, the measures to promote implementation, and the people involved. Cost considerations have to date rarely been included.Well designed programmes for implementing the guidelines are usually lacking: implementation is often restricted to mailing the guidelines or presenting them in journals.As yet, there is a scarcity of any monitoring of the acceptance, use and impact of these guidelines.Despite these limitations, positive trends can be seen in guideline development in Europe. These include: a shift towards guidelines based on the best evidence available, and developed through formal, systematic and explicit procedures; more attention to effective implementation of practice guidelines; and, more attention to the role of the patient in guideline development, as well as in shared decision-making based on guidelines.Such trends mark the direction in which the development of clinical guidelines in Europe will probably progress. However, in a few year’ time, there will be the danger of an overload of guidelines, which may be conflicting in their advice to doctors thus creating confusion and resistance. Specific criteria for high quality clinical practice guidelines and continuous improvement in the procedures for developing and implementing guidelines will be an important next step.     

Current initiatives in Germany for translating national guidelines into reality - a survey

The role of practice guidelines as a tool for quality management in health care is now widely accepted in Germany- not only by health professionals, but also in politics. The physicians' professional associations as well as health care authorities (physicians' self-governmental bodies) and parliament introduced several incentives and regulations, aiming at a regular use of guidelines in health care. Among these the German guideline clearinghouse with the systematic approach towards identification, dissemination, and implementation of best available evidence-based guidelines, as well as the country-wide implementation of disease management guidelines seem to be effective and efficient in quality management as well as in patient care management in the German health care system. The article gives an overview on background, procedures and barriers to country-wide implementation of clinical practice guidelines within a social security health care system.     

Guidelines for the Provision and Assessment of Nutrition Support Therapy in the Pediatric Critically Ill Patient: Society of Critical Care Medicine and American Society for Parenteral and Enteral Nutrition

This document represents the first collaboration between 2 organizations—the American Society for Parenteral and Enteral Nutrition and the Society of Critical Care Medicine—to describe best practices in nutrition therapy in critically ill children. The target of these guidelines is intended to be the pediatric critically ill patient (>1 month and <18 years) expected to require a length of stay >2–3 days in a PICU admitting medical, surgical, and cardiac patients. In total, 2032 citations were scanned for relevance. The PubMed/MEDLINE search resulted in 960 citations for clinical trials and 925 citations for cohort studies. The EMBASE search for clinical trials culled 1661 citations. In total, the search for clinical trials yielded 1107 citations, whereas the cohort search yielded 925. After careful review, 16 randomized controlled trials and 37 cohort studies appeared to answer 1 of the 8 preidentified question groups for this guideline. We used the GRADE criteria (Grading of Recommendations, Assessment, Development, and Evaluation) to adjust the evidence grade based on assessment of the quality of study design and execution. These guidelines are not intended for neonates or adult patients. The guidelines reiterate the importance of nutrition assessment—particularly, the detection of malnourished patients who are most vulnerable and therefore may benefit from timely intervention. There is a need for renewed focus on accurate estimation of energy needs and attention to optimizing protein intake. Indirect calorimetry, where feasible, and cautious use of estimating equations and increased surveillance for unintended caloric underfeeding and overfeeding are recommended. Optimal protein intake and its correlation with clinical outcomes are areas of great interest. The optimal route and timing of nutrient delivery are areas of intense debate and investigations. Enteral nutrition remains the preferred route for nutrient delivery. Several strategies to optimize enteral nutrition during critical illness have emerged. The role of supplemental parenteral nutrition has been highlighted, and a delayed approach appears to be beneficial. Immunonutrition cannot be currently recommended. Overall, the pediatric critical care population is heterogeneous, and a nuanced approach to individualizing nutrition support with the aim of improving clinical outcomes is necessary.     

Implementation of oral health recommendations into two residential aged care facilities in a regional Australian city

Background Residents of aged care facilities usually have a large number of oral health problems. Residents who suffer from dementia are at particular risk. A systematic review of the best available evidence with regard to maintaining the oral health of older people with dementia in residential aged care facilities provided a number of recommendations. Objectives The aim of the implementation project was to introduce evidence-based oral hygiene practices for patients with dementia in two publicly funded residential aged care facilities and monitor for changes in nursing awareness, knowledge, documentation and practice to improve patient outcomes and ensure appropriate accreditation standards were met. An additional aim was to identify barriers and strategies to overcome barriers to implementation of evidence-based recommendations. Methods Two facilities, a 40-bed facility and a 71-bed facility in the health service district of the regional Australian city of Toowoomba, provided the setting. A quality improvement approach was taken, using a number of strategies from the National Health and Medical Research Council guidelines for implementation studies. The implementation involved a number of stages, including project development, interactive oral health education, oral audits of residents, changes to oral hygiene practice via care plans and critical reflection. Results The multidisciplinary approach to improving oral healthcare appeared to improve knowledge and awareness and move oral health practices in facilities closer to best practice. Specialised training in oral health was provided to a Clinical Nurse Consultant. Regular oral audits were introduced and facility staff were trained in the use of the oral audit tool. Care plans at one facility were of better quality and more comprehensive than before the intervention. Comments made during critical reflection suggested improvements in the oral health of residents, increased use of oral swabs and saliva substitutes, improved care of dentures and mention of the use of mouth props in resident care plans. There was also some evidence that changes brought about by the implementation are sustainable. Conclusion The majority of recommendations provided in the systematic review of oral healthcare for dementia patients were applicable to the applied context. The importance of day-to-day leaders was highlighted by the apparently varied outcomes across target facilities. The quality improvement approach would appear to have considerable advantages when applied to improving practice in residential aged care.     

Effect of clinical guidelines in nursing, midwifery, and the therapies: a systematic review of evaluations.

BACKGROUND: Although nursing, midwifery, and professions allied to medicine are increasingly using clinical guidelines to reduce inappropriate variations in practice and ensure higher quality care, there have been no rigorous overviews of their effectiveness, 18 evaluations of guidelines were identified that meet Cochrane criteria for scientific rigor. METHODS: Guideline evaluations conducted since 1975 which used a randomised controlled trial, controlled before and after, or interrupted time series design were identified through a combination of database and hand searching. RESULTS: 18 studies met the inclusion criteria. Three studies evaluated guideline dissemination or implementation strategies, nine compared use of a guideline with a no guideline state; six studies examined skill substitution: performance of nurses operating according to a guideline were compared with standard care, generally provided by a physician. Significant changes in the process of care were found in six out of eight studies measuring process and in which guidelines were expected to have a positive impact on performance. In seven of the nine studies measuring outcomes of care, significant differences in favour of the intervention group were found. Skill substitution studies generally supported the hypothesis of no difference between protocol driven by nurses and care by a physician. Only one study included a formal economic evaluation, with equivocal findings. CONCLUSIONS: Findings from the review provide some evidence that care driven by a guideline can be effective in changing the process and outcome of care. However, many studies fell short of the criteria of the Cochrane Effective Practice and Organisation of Care Group (EPOC) for methodological quality.     

The cycle of change: implementing best-evidence clinical practice

To improve health outcomes, effective and systematic mechanismsto foster the adoption of evidence-based guideline recommendationsinto routine practice need to be identified. A cyclical processfor achieving this objective involving three key phases is suggested. Phase 1. Writing actionable best-evidence guidelines that prioritizekey recommendations while indicating the levels of adoptionneeded for population health benefits to be accomplished. Phase 2. Developing implementation plans for the priority guideline recommendations.These should systematically consider skills training and accreditation;social influences including opinion leaders and patient influences;environmental factors; monitoring and feedback; and incentivesfor clinical change. Phase 3. Pilot testing the effectiveness of proposed approaches in producingthe desired clinical changes. If implementation requires systemchanges and evaluation at an organizational level, the use ofalternative research designs to the randomized controlled trialcould be considered. The purpose evaluation would be to enablerefinement of the implementation plans before widespread dissemination.     

Implementing Clinical Practice Guidelines in occupational therapy practice: Recommendations from the research evidence

Background: Clinical Practice Guidelines (CPGs) are prominent tools in evidence‐based practice which integrate research evidence, clinical expertise and client input to develop recommendations for specific clinical circumstance. With the push to use research evidence in health care, it is anticipated that occupational therapists will become increasingly involved in implementing CPGs in practice. The research evidence has revealed several factors that can affect guideline uptake, and a variety of strategies that can facilitate implementation. Methods: This narrative review examines the health‐related literature in CPGs to answer the following questions. Based on the research evidence, (i) what are the factors that may influence guideline implementation? (ii) What implementation strategies may enhance guideline implementation? Results: Factors within the guideline itself (e.g. quality, complexity and clarity), within the practitioner (e.g. experience, perceptions and beliefs), the patient (e.g. expectations and preferences) and the practice context (e.g. resource availability, organisational culture and opinion leaders) can all affect implementation success. Currently, there is no conclusive evidence to support the use of one implementation strategy over another, in all situations. The choice of implementation strategy must take into account the guideline to be implemented, the practice context and the anticipated challenges to implementation. Conclusions: By understanding the factors that can influence implementation and the strategies for successful implementation, occupational therapists will be better prepared to implement guidelines. Recommendations to assist with guideline uptake and implementation are provided.     

From clinical practice guidelines towards quality assurance

Clinical practice guidelines have been introduced to assist decision making at the bedside of individual patients. Guidelines are also increasingly regarded as being an indispensable part of professional quality systems. Guidelines are important tools to improve knowledge-management, processes and outcomes in healthcare. They aim to assist professional and patient decisions especially in those areas of healthcare where considerable variation or potential for improvement exist and they can provide a foundation for assessing and evaluating the quality and effectiveness of healthcare in terms of measuring processes and outcomes. Quality indicators or performance measures based on guideline recommendations are necessary to evaluate the usefulness of guidelines and the appropriateness of healthcare delivery. Guideline recommendations are the tools for healthcare professionals to develop strategies for quality improvement in case deviations from desired processes or outcomes are identified by the measurement of quality indicators.     

The enteral vs parenteral nutrition debate revisited

Many trials and several meta-analyses have been devoted to comparing enteral with parenteral nutrition support. In this review, these studies are subjected to critical analysis with particular emphasis on their methodology and clinical relevance. Evidence is produced to suggest that the heterogeneous patient populations of the studies and the rigid approach taken to comparing different nutrition therapies inter alia render their conclusions highly questionable and of very doubtful clinical significance. An alternative approach to nutrition research is suggested in which strategies of nutrition support rather than fixed menus are compared. It is suggested that objective measures of intestinal function be evaluated more fully in patients requiring nonvolitional nutrition support, and these are briefly reviewed. In addition, a more scientific approach to evaluating the physiological effects of nutrition support, including chemical tagging and evaluation of muscle function, is recommended.     

National clinical guidelines and home parenteral nutrition

Research-based guidelines provide the best evidence and are the cornerstones of achieving quality outcomes for home parenteral nutrition (HPN) patients and their families. However, evidence about the implementation of HPN guideline recommendations is rarely reported. The purpose of this clinical practice project was to compare HPN clinical guidelines with baseline data reported by HPN patients from 1990-2010 and to explore possible facilitators or barriers to the implementation of guidelines in clinical practice. Methods included PubMed literature searches for HPN clinical guidelines and comparison of the retrieved guidelines with HPN clinical data reported by HPN patients from 3 separate studies conducted in the United States from 1990-2010. Results of reviewing published HPN guidelines found recommendations based primarily on expert opinion and included the appropriate use of HPN, coordination of care by teams of experts, use of dedicated ports, salvaging catheters when possible, and bowel transplantation. Comparison of baseline data over the 2 decades indicated that guidelines for the appropriate use and types of central venous catheters were being implemented, but there was little evidence that most HPN patients had their care coordinated by multidisciplinary teams. Conclusions are that most HPN guideline recommendations were being implemented in practice except for the care delivered by multidisciplinary experts. To ensure quality HPN outcomes, multidisciplinary teams of HPN experts are needed as are large data sets that will provide indicators of guideline use and outcomes. Furthermore, research is needed so that recommendations are not based totally on expert consensus.
