The resistance to changing guidelines – what are the challenges and how to meet them

Nurse academics' understanding and experience of guidelines in clinical practice

BACKGROUND

The literature suggests there are numerous factors relating to adherence to guidelines in clinical practice. It is proposed that a potential barrier to adherence is that nurses may not view guidelines as mandatory and instead see them as more of a tool for guidance.

AIMS

To analyse nurse educators' understanding and experience of the term 'guidelines' in relation to clinical practice and clinical decision-making.

METHODS

One focus group interview was undertaken; the data collected were analysed using interpretive phenomenological analysis.

FINDINGS

Data analysis resulted in the identification of three personal experiential themes: lack of consensus regarding a definition of 'guideline', barriers to guideline adherence, and the impact of clinical guidelines on professional judgement.

CONCLUSION

Nurse academics discussed a lack of understanding of what guidelines are and how this may influence their decision to follow guidelines when making clinical decisions. When guidelines are viewed as 'recommendations' rather than 'rules' then nurses may be inclined to use their own intuition and experience instead when decision-making. As this may lead to inconsistent use of guidelines in clinical practice, further research is recommended to investigate potential implications.

Barriers and facilitators to implementation of an exercise and education programme for osteoarthritis: a qualitative study using the consolidated framework for implementation research

Targeted efforts to better understand the barriers and facilitators of stakeholders and healthcare settings to implementation of exercise and education self-management programmes for osteoarthritis (OA) are needed. This study aimed to explore the barriers and facilitators to the implementation of Good Life with osteoArthritis in Denmark (GLA:D), a supervised group guideline-based OA programme, across Irish public and private healthcare settings. Interviews with 10 physiotherapists (PTs; 8 public) and 9 people with hip and knee OA (PwOA; 4 public) were coded by the Consolidated Framework for Implementation Research (CFIR) constructs in a case memo (summary, rationale, quotes). The strong positive/negative implementation determinants were identified collaboratively by rating the valence and strength of CFIR constructs on implementation. Across public and private settings, PTs and PwOA strongly perceived GLA:D Ireland as evidence-based, with easily accessible education and modifiable marketing/training materials that meet participants' needs, improve skills/confidence and address exercise beliefs/expectations. Despite difficulties in scheduling sessions (e.g., work/caring responsibilities), PTs in public and private settings perceived advantages to implementation over current clinical practice (e.g., shortens waiting lists). Only PTs in public settings reported limited availability of internal/external funding, inappropriate space, marketing/training tools, and inadequate staffing. Across public and private settings, PwOA reported adaptability, appropriate space/equipment and coaching/supervision, autonomy, and social support as facilitators. Flexible training and tailored education for stakeholders and healthcare settings on guideline-based OA management may promote implementation. Additional support on organising (e.g., scheduling clinical time), planning (e.g., securing appropriate space, marketing/training tools), and funding (e.g., accessing dedicated internal/external grants) may strengthen implementation across public settings.

APPRAISE-RS: Automated, updated, participatory, and personalized treatment recommender systems based on GRADE methodology

Purpose

Clinical practice guidelines (CPGs) have become fundamental tools for evidence-based medicine (EBM). However, CPG suffer from several limitations, including obsolescence, lack of applicability to many patients, and limited patient participation. This paper presents APPRAISE-RS, which is a methodology that we developed to overcome these limitations by automating, extending, and iterating the methodology that is most commonly used for building CPGs: the GRADE methodology.

Method

APPRAISE-RS relies on updated information from clinical studies and adapts and automates the GRADE methodology to generate treatment recommendations. APPRAISE-RS provides personalized recommendations because they are based on the patient's individual characteristics. Moreover, both patients and clinicians express their personal preferences for treatment outcomes which are considered when making the recommendation (participatory). Rule-based system approaches are used to manage heuristic knowledge.

Results

APPRAISE-RS has been implemented for attention deficit hyperactivity disorder (ADHD) and tested experimentally on 28 simulated patients. The resulting recommender system (APPRAISE-RS/TDApp) shows a higher degree of treatment personalization and patient participation than CPGs, while recommending the most frequent interventions in the largest body of evidence in the literature (EBM). Moreover, a comparison of the results with four blinded psychiatrist prescriptions supports the validation of the proposal.

Conclusions

APPRAISE-RS is a valid methodology to build recommender systems that manage updated, personalized and participatory recommendations, which, in the case of ADHD includes at least one intervention that is identical or very similar to other drugs prescribed by psychiatrists.

Facilitators and barriers for home-based monitoring to time frozen embryo transfers in IVF among women and healthcare providers

STUDY QUESTION

What are the facilitators and barriers concerning the implementation of home-based monitoring for natural cycle frozen embryo transfer (NC-FET) from the perspectives of patients and healthcare providers in the Netherlands?

SUMMARY ANSWER

The most important facilitator was optimal pregnancy chance for both the patients and healthcare providers, and the most important barriers were the risk of missing an ovulation for the patients and laboratory capacity for the healthcare providers.

WHAT IS KNOWN ALREADY

The share of FET cycles in IVF treatments is increasing and, therefore, it is important to optimize protocols for FET. Monitoring of ovulation, which is used in NC-FET, can be hospital-based (ultrasounds and ovulation triggering) or home-based (LH urine tests). Home-based monitoring has the advantage of being the most natural protocol for FET and provides the feeling of empowerment and discretion for patients. A systematic approach for the implementation of home-based monitoring has to start with an exploration of the perspectives of all stakeholders.

STUDY DESIGN SIZE DURATION

Stakeholders (patients and healthcare providers) involved in the implementation process in the Netherlands participated in the present study. Patients were represented by the Dutch Patient Organisation for Couples with Fertility Problems (FREYA) and healthcare providers were represented by gynaecologists and their society (The Netherlands Society of Obstetrics and Gynaecology), embryologists and their society (The Dutch Federation of Clinical Embryology) as well as fertility doctors. A panel of experts hypothesized on barriers and facilitators for the implementation of home-based monitoring during the proposal phase of the Antarctica-2 randomized controlled trial (RCT).

PARTICIPANTS/MATERIALS SETTING METHODS

All stakeholders were represented during the study. Two different questionnaires were developed in order to investigate facilitators and barriers for the patients and for healthcare providers. The facilitators and barriers were ranked on a scale of 1-10 with 10 being the most important. Based on our power analysis, we aimed for a minimum of 300 completed questionnaires for the patients and a minimum of 90 completed questionnaires for the healthcare providers. Facilitators and barriers were analysed using frequencies, mean (SD) and ranking.

MAIN RESULTS AND THE ROLE OF CHANCE

A total of 311 patients filled out the questionnaire of whom 86.8% underwent FET previously. The most important facilitator for the patients was to implement the strategy with the highest chance of pregnancy (mean 9.7; 95% CI 9.6-9.7) and the most important barrier was risk of missing ovulation (mean 8.4; 95% CI 8.2-8.6). A total of 96 healthcare providers filled out the questionnaire. According to healthcare providers, patients would accept the strategy when it causes less interference with their work and private life (mean 7.5; 95% CI 7.1-8.0) and has a low risk of missing the ovulation (mean 7.6; 95% CI 7.1-8.0). The most important facilitator for the implementation of home-based monitoring for healthcare providers was optimizing cumulative pregnancy rates (mean 8.1; 95% CI 7.7-8.4) and the most important barrier was the lack of laboratory capacity and flexibility (mean 6.4; 95% CI 5.8-7.0).

LIMITATIONS REASONS FOR CAUTION

Facilitators and barriers were selected based on expert opinion. Currently, there are no validated questionnaires that aim to assess facilitators and barriers for the implementation of treatments in fertility care.

WIDER IMPLICATIONS OF THE FINDINGS

During our study, we gained insight into barriers and facilitators for the implementation of home-based monitoring of NC-FET at an early phase. Early sharing and discussion of the results of this study with all stakeholders involved should stimulate a fast incorporation in guidelines, especially as key professionals in guideline development took part in this study. Also, based on our results, we can advise guideline developers to add tools to the guideline that may help overcome the implementation barriers.

Perspectives on Implementing the Patient Health Questionnaire-4 in Low-Vision Service Organizations to Screen for Depression and Anxiety

Purpose

To describe the process of implementing a screening questionnaire for depression and anxiety, the Patient Health Questionnaire-4 (PHQ-4), in low-vision service (LVS) organizations.

Methods

This study consisted of three parts: (1) a usability study combined with semistructured interviews, in which clients (n = 10) of LVS organizations expressed their preference for using the PHQ-4; (2) a feasibility study, in which the PHQ-4 was implemented on a small scale and its use was evaluated, involving health care providers (n = 6) and clients (n = 9); and (3) semistructured interviews to identify barriers and facilitators for implementing the PHQ-4 according to health care providers (n = 6) and managers (n = 4) of LVS organizations. Results were integrated into themes and linked to constructs of the Consolidated Framework for Implementation Research (CFIR).

Results

Six themes were derived from the substudies: (1) quality of the intervention, (2) applicability for clients of LVS organizations, (3) attitude and needs of clients, (4) attitude of health care providers, (5) support within LVS organizations, and (6) embedment in current practice. Results could be linked to 12 CFIR constructs. The constructs "relative advantage," "patient needs and resources," and "available resources" emerged most prominently in our themes as either barrier or facilitator.

Conclusions

The PHQ-4 seems an appropriate screening instrument for use in LVS organizations because of its quality and adaptable use. It might provide opportunities to timely detect depression and anxiety, but challenges in implementing the PHQ-4 should be considered.

Translational Relevance

Barriers and facilitators for implementing the PHQ-4 may also apply to implementing other questionnaires in LVS organizations.

A cross sectional, observational study to evaluate the surgeons' knowledge and perspective on preoperative fasting guidelines in a tertiary care teaching hospital in Southern India

Background and Aims

The preoperative fasting orders given by the Anesthesiologists as per ASA and Enhanced Recovery After Surgery protocol, are often modified by the surgeons, for practical convenience, which can end up with patients being starved for prolonged periods of time. Hence, this study was conducted among various specialty surgical colleagues, to evaluate the knowledge and their perspective regarding patients' preoperative fasting guidelines.

Material and Methods

A validated questionnaire was distributed to 68 surgeons belonging to various surgical specialties, which included consultants and postgraduate residents. The surgeons were grouped as surgeons operating only on children, only on adults, and on adults and children (mixed). Data were summarized using the mean (SD)/median for continuous variables and categorical data were expressed as frequency and percentage. The difference in knowledge score, among the surgeons of three groups, was analyzed using ANOVA, with Bonferroni as post hoc.

Results

This study shows an overall decrease in knowledge (score of 6.13 ± 1.74) about preoperative fasting guidelines among surgeons. We found that the level of knowledge about preoperative fasting guidelines and complications was higher among surgeons who operate only on children (score of 7.05) as compared to surgeons operating only on adults (score 5.5) and adults and children (mixed) (score 6.1), which was statistically significant (P = 0.013). We found no difference in knowledge level based on designation and gender. All the surgeons uniformly had the perspective that patients have to be kept fasting preoperatively.

Conclusion

Preoperative fasting orders for all surgical patients, especially for vulnerable patients such as children and geriatrics, should be administered by the anesthesiologist or surgeon who is familiar with fasting guidelines. We intend to raise the awareness of fasting guidelines of surgical colleagues by putting up placards and posters in the wards.

Individual, health system, and contextual barriers and facilitators for the implementation of clinical practice guidelines: a systematic metareview

INTRODUCTION

Clinical practice guidelines (CPGs) are designed to improve the quality of care and reduce unjustified individual variation in clinical practice. Knowledge of the barriers and facilitators that influence the implementation of the CPG recommendations is the first step in creating strategies to improve health outcomes. The present systematic meta-review sought to explore the barriers and facilitators for the implementation of CPGs.

METHODS

A search was conducted in the PubMed, Embase, Cochrane, Health System Evidence and International Guideline Library (G-I-N) databases. Systematic reviews of qualitative, quantitative or mixed-methods studies that identified barriers or facilitators for the implementation of CPGs were included. The selection of the title and abstract, the evaluation of the full text, extraction of the data and the quality assessment were carried out by two independent reviewers. To summarise the evidence, we grouped the barriers and facilitators according to the following contexts: political and social, health organisational system, guidelines, health professionals and patients.

RESULTS

Overall, 25 systematic reviews were selected. The relevant barriers in the social-political context were the absence of a leader, difficulties with teamwork and a lack of agreement with colleagues. Relevant barriers in the health system were a lack of time, financial problems and a lack of specialised personnel. Barriers of the CPGs included a lack of clarity and a lack of credibility in the evidence. Regarding the health professional, a lack of knowledge about the CPG and confidence in oneself were relevant. Regarding patients, a negative attitude towards implementation, a lack of knowledge about the CPG and sociocultural beliefs played a role. Some of the most frequent facilitators were consistent leadership, commitment of the members of the team, administrative support of the institution, existence of multidisciplinary teams, application of technology to improve the practice and education regarding the guidelines.

CONCLUSIONS

The barriers and facilitators described in this review are factors that influence the implementation of evidence in clinical practice. Knowledge of these factors should contribute to the development of a theoretical basis for the creation of CPG implementation strategies to improve professional practice and health outcomes for patients.

Towards standardisation of evidence-based clinical care process specifications

There is a strong push towards standardisation of treatment approaches, care processes and documentation of clinical practice. However, confusion persists regarding terminology and description of many clinical care process specifications which this research seeks to resolve by developing a taxonomic characterisation of clinical care process specifications. Literature on clinical care process specifications was analysed, creating the starting point for identifying common characteristics and how each is constructed and used in the clinical setting. A taxonomy for clinical care process specifications is presented. The De Bleser approach to limited clinical care process specifications characterisation was extended and each clinical care process specification is successfully characterised in terms of purpose, core elements and relationship to the other clinical care process specification types. A case study on the diagnosis and treatment of Type 2 Diabetes in the United Kingdom was used to evaluate the taxonomy and demonstrate how the characterisation framework applies. Standardising clinical care process specifications ensures that the format and content are consistent with expectations, can be read more quickly and high-quality information can be recorded about the patient. Standardisation also enables computer interpretability, which is important in integrating Learning Health Systems into the modern clinical environment. The approach presented allows terminologies for clinical care process specifications that were widely used interchangeably to be easily distinguished, thus, eliminating the existing confusion.

Implementing a toolkit for the prevention, management and control of carbapenemase-producing Enterobacteriaceae in English acute hospitals trusts: a qualitative evaluation

BACKGROUND

Antimicrobial resistance is an increasing problem in hospitals world-wide. Following other countries, English hospitals experienced outbreaks of carbapenemase-producing Enterobacteriaceae (CPE), a bacterial infection commonly resistant to last resort antibiotics. One way to improve CPE prevention, management and control is the production of guidelines, such as the CPE toolkit published by Public Health England in December 2013. The aim of this research was to investigate the implementation of the CPE toolkit and to identify barriers and facilitators to inform future policies.

METHODS

Acute hospital trusts (N = 12) were purposively sampled based on their self-assessed CPE colonisation rates and time point of introducing local CPE action plans. Following maximum variation sampling, 44 interviews with hospital staff were conducted between April and August 2017 using a semi-structured topic guide based on the Capability, Opportunity, Motivation and Behaviour Model and the Theoretical Domains Framework, covering areas of influences on behaviour. Interviews were audio-recorded, transcribed verbatim and analysed using thematic analysis.

RESULTS

The national CPE toolkit was widely disseminated within infection prevention and control teams (IPCT), but awareness was rare among other hospital staff. Local plans, developed by IPCTs referring to the CPE toolkit while considering local circumstances, were in place in all hospitals. Implementation barriers included: shortage of isolation facilities for CPE patients, time pressures, and competing demands. Facilitators were within hospital and across-hospital collaborations and knowledge sharing, availability of dedicated IPCTs, leadership support and prioritisation of CPE as an important concern. Participants using the CPE toolkit had mixed views, appreciating its readability and clarity about patient management, but voicing concerns about the lack of transparency on the level of evidence and the practicality of implementation. They recommended regular updates, additional clarifications, tailored information and implementation guidance.

CONCLUSIONS

There were problems with the awareness and implementation of the CPE toolkit and frontline staff saw room for improvement, identifying implementation barriers and facilitators. An updated CPE toolkit version should provide comprehensive and instructive guidance on evidence-based CPE prevention, management and control procedures and their implementation in a modular format with sections tailored to hospitals' CPE status and to different staff groups.

Management of stable angina pectoris in private healthcare settings in South Africa

Aim

Angina pectoris continues to affect multitudes of people around the world. In this study the management of stable angina pectoris in private healthcare settings in South Africa (SA) was investigated. In particular, we reviewed the frequency of medical versus surgical interventions when used as first-line therapy.

Methods

This was a retrospective inferential study carried out using records of patients in private healthcare settings. All cases that were authorised for reimbursement by medical aid schemes for revascularisation between 2009 and 2014 were retrieved and a database was created. Data were analysed using MicrosoftR Excel and GraphPad PrismR version 5. The differences (where applicable) were considered statistically significant if the p-value was ≤ 0.05.

Results

Nine hundred and twenty-two patients, consisting of 585 males (average age 64.7 years; SD 12.9) and 337 females (average age 65.5 years; SD 14.3), met the inclusion criteria. One hundred and seventy-eighty or 54%, 156 (43%) and 86 (63%) patients with hypertension, hyperlipidaemia and diabetes, respectively, were treated with surgery only. For these patients, percutaneous coronary interventions (PCIs) were significantly (p < 0.0001) preferred first-line interventions over optimal medical therapy (OMT). Four hundred and thirty-six or 47% of all patients studied were managed with surgery only, while only 25% (227) were managed with OMT. It took 60 months (five years) for patients who were treated with OMT before their first surgical intervention(s) to require the second revascularisation. About 71% of patients who received medical therapy were placed on only one drug, the so called sub-optimal medical therapy (SOMT).

Conclusion

The management of stable angina pectoris in private healthcare settings in SA is skewed towards surgical interventions as opposed to OMT. This is contrary to what consistent scientific evidence and international treatment guidelines suggest.

Introduction of clerking pro forma for surgical spinal patients at the Royal National Orthopaedic Hospital NHS Trust (London): an audit cycle

As a tertiary referral centre of spinal surgery, the Royal National Orthopaedic Hospital (RNOH) handles hundreds of spinal cases a year, often with complex pathology and complex care needs. Despite this, issues were raised at the RNOH following lack of sufficient documentation of preoperative and postoperative clinical findings in spinal patients undergoing major surgery. This is not in keeping with guidelines provided by the Royal College of Surgeons. The authors believe that a standardised clerking pro forma for surgical spinal patients admitted to RNOH would improve the quality of care provided. Therefore, the use of a standard clerking pro forma for all surgical spinal patients could be a useful tool enabling improvements in patients care and safety in keeping with General Medical Council/National Institute for Health and Care Excellence guidelines. An audit (with closure of loop) looking into the quality of the preoperative and postoperative clinical documentation for surgical spinal patients was carried out at the RNOH in 2016 (retrospective case note audit comparing preintervention and postintervention documentation standards). Our standardised pro forma allows clinicians to best utilise their time and standardises examination to be compared in a temporal manner during the patients admission and care. It is the authors understanding that this work is a unique study looking at the quality of the admission clerking for surgical spinal patients. Evidently, there remains work to be done for the widespread utilisation of the pro forma. Early results suggest that such a pro forma can significantly improve the documentation in admission clerking with improvements in the quality of care for patients.

Potential facilitators and barriers to adopting standard treatment guidelines in clinical practice

Purpose The purpose of this paper is to assess medicines information sources accessed by clinicians, if sources differed in theory and practice and to find out the barriers and facilitators to effective guideline adoption. Design/methodology/approach In all, 183 doctors were surveyed. Barriers and facilitators were classified as: communication; potential adopters; innovation; organization characteristics and environmental/social/economic context. Findings Most of the clinicians accessed multiple information sources including standard treatment guidelines, but also consulted seniors/colleagues in practice. The top three factors influencing clinical practice guideline adoption were innovation characteristics, environmental context and individual characteristics. The respondents differed in the following areas: concerns about flexibility offered by the guideline; denying patients' individuality; professional autonomy; insights into gaps in current practice and evidence-based practice; changing practices with little or no benefit. Barriers included negative staff attitudes/beliefs, guideline integration into organizational structures/processes, time/resource constraints. Fearing third parties (government and insurance companies) restricting medicines reimbursement and poor liability protection offered by the guidelines emerged as the barriers. Facilitators include aligning organizational structures/processes with the innovation; providing leadership support to guide diffusion; increasing awareness and enabling early innovation during pre/in-service training, with regular feedback on outcomes and use. Practical implications Guideline adoption in clinical practice is partly within doctors' control. There are other key prevailing factors in the local context such as environmental, social context, professional and organizational culture affecting its adoption. Organizational policy and accreditation standards necessitating adherence can serve as a driver. Originality/value This survey among clinicians, despite limitations, gives helpful insights. While favourable attitudes may be helpful, clinical adoption could be improved more effectively by targeting barriers.

Frequency and nature of coroners' recommendations from injury-related deaths among nursing home residents: a retrospective national cross-sectional study

BACKGROUND

Coroners are tasked with the investigation of unnatural and unexpected deaths. In Australia, the coroner's role also includes making recommendations for promoting interventions to improve public safety. However, the coroners' role in public health and safety in the aged care setting is an underexplored area of research.

OBJECTIVES

To describe the frequency and nature of coroners' recommendations for prevention of harm from injury-related deaths among nursing home residents in Australia.

SETTING

Accredited nursing homes in Australia.

SUBJECTS

Nursing home residents whose deaths resulted from external causes occurring between 1 July 2000 and 31 December 2013 and notified to a coroner.

MEASUREMENTS

Coroners' recommendations were identified and extracted from the National Coronial Information System. Descriptive statistical techniques were used to calculate the frequency and proportion of recommendations made. The nature of recommendations was quantified using a method comprising seven elements derived from internationally accepted and applied public health conceptual models of mortality causation and prevention.

RESULTS

Coroners made recommendations about the prevention of harm in 53 of the 3289 (1.6%) external cause deaths of nursing home residents. Recommendations were most frequently made for deaths resulting from falls; however, the rate of recommendations per 1000 deaths was highest for thermal mechanisms and complications of clinical care. Most recommendations described the 'countermeasure' element, but rarely specified a timeframe for implementation.

CONCLUSION

Coroners' recommendations need to be further enhanced in the age care setting. The development of national and international guidelines on best practice in the formulation of effective recommendations should be undertaken.

Preoperative Fasting among Adult Patients for Elective Surgery in a Kenyan Referral Hospital

Background. Preoperative fasting (POF) is physiologically and precautionary important during anesthesia and surgery. POF from midnight has been practiced despite the recommended shorter practice. Objective. Assessing preoperative fasting among adult patients scheduled for elective surgery at Kenyatta National Hospital (KNH). Methods. A descriptive cross-sectional study involving 65 surgical patients. A questionnaire of mixed questions on demographics, reasons, source of instructions, opinion on instructions, time, premedication practices, outcome, and complains on NPO was used. Analysis was quantitatively done with SPSS v. 22. Ethical approval was obtained from KNH-UoN ERC. Results. Of the respondents 93.8% lacked knowledge on the correct reasons for POF and felt that the instructions were unclear and less important <50%. POF instructions were administered by nurses 80%, anesthetists 15%, and surgeons 5%. Most of respondents (73.8%) fasted > 15 hours. The POF outcomes were rated moderately challenging as follows: prolonged wait for surgery 44.6%, thirst 43.1%, hunger 36.9%, and anxiety 29.2%. Conclusion. Nurses are critical in providing POF instructions and care, and patient knowledge level is a mirror reflection of the quality of interventions. This underscores the need to build capacity for nurses and strengthen the health system to offer individualized preoperative interventions as well as monitoring and clinical auditing of fasting practices.

Administration Safety of Blood Products - Lessons Learned from a National Registry for Transfusion and Hemotherapy Practice

BACKGROUND

Compared to blood component safety, the administration of blood may not be as safe as intended. The German Interdisciplinary Task Force for Clinical Hemotherapy (IAKH) specialized registry for administration errors of blood products was chosen for a detailed analysis of reports.

METHODS

Voluntarily submitted critical incident reports (n = 138) from 2009 to 2013 were analyzed.

RESULTS

Incidents occurred in the operation room (34.1%), in the ICU (25.2%), and in the peripheral ward (18.5%). Procedural steps with errors were administration to the patient (27.2%), indication and blood order (17.1%), patient identification (17.1%), and blood sample withdrawal and tube labeling (18.0%). Bedside testing (BST) of blood groups avoided errors in only 2.6%. Associated factors were routine work conditions (66%), communication error (36%), emergency case (26%), night or weekend team (39%), untrained personnel (19%). Recommendations addressed process and quality (n = 479) as well as structure quality (n = 314). In 189 instances, an IT solution would have helped to avoid the error.

CONCLUSIONS

The administration process is prone to errors at the patient assessment for the need to transfuse and the application of blood products to patients. BST is only detecting a minority of handling errors. According to the expert recommendations for practice improvement, the potential to improve transfusion safety by a technical solution is considerable.

Use and implementation of standard operating procedures and checklists in prehospital emergency medicine: a literature review

OBJECTIVES

This review aimed to analyze published literature to introduce the use and implementation of standard operating procedures (SOPs) and checklists in prehospital emergency medicine and their impact on guideline adherence and patient outcome.

METHODS

An English literature search was carried out using the Cochrane Library, MEDLINE, EMBASE, Springer, Elsevier, and ProQuest databases. Original articles describing the use and implementation of SOPs or checklists in prehospital emergency medicine were included. Editorials, comments, letters, bulletins, news articles, conference abstracts, and notes were excluded from the analysis. Relevant information was extracted relating to application areas, development of SOPs/checklists, educational preparation and training regarding SOPs/checklists implementation, staff attitudes and the effects of SOPs/checklists use on guideline adherence and patient outcomes.

RESULTS

The literature search found 2187 potentially relevant articles, which were narrowed down following an abstract review and a full text review. A final total of 13 studies were identified that described the use and implementation of SOPs (9 studies) and checklists (4 studies) in different areas of prehospital emergency medicine including prehospital management of patients with acute exacerbated chronic obstructive pulmonary disease and acute coronary syndrome, prehospital airway management, medical documentation, Emergency Medical Services triage, and transportation of patients.

CONCLUSIONS

The use and implementation of SOPs and checklists in prehospital emergency medicine have shown some benefits of improving guidelines adherence and patient outcomes in airway management, patient records, identification and triage, and other prehospital interventions. More research in this area is necessary to optimize the future use and implementation of SOPs and checklists to improve emergency personnel performance and patient outcomes.

[Knowledge and implementation of the S3 guideline on delirium management in Germany]

BACKGROUND

Delirium is a common complication in critical care. The syndrome is often underestimated due to its potentially no less dangerous course as a hypoactive delirium. Therefore, current guidelines ask for a structured, regular and routine screening in all intensive care units. If delirium is diagnosed, symptomatic therapy should be initiated promptly.

OBJECTIVES

The aim of the current study was to evaluate recent German anesthetists' strategies regarding delirium care compared to the German guidelines for sedation and delirium in intensive care.

METHODS

In an online survey German hospitals' senior anesthetists (n = 922) were interviewed anonymously between May and June 2015 regarding guideline use in delirium management in German intensive care units. In 33 direct questions the anesthetists were invited to answer items regarding the structure of their hospitals, intensive care and delirium therapy in order to review their knowledge of the German delirium guidelines that expired in 2014.

RESULTS

The 249 senior anesthetists who responded to the survey, can be associated with (or represent) a quarter of German intensive care beds and cases, respectively. In every tenth clinic that runs an intensive care unit the guideline was unknown. In three of four intensive care units physicians specified a preferred delirium score, the CAM-ICU (49.4 %) is used most frequently. With knowledge of the guidelines more often a recommended delirium score is used (p = 0.017). However, only 53.6 % of the respondents ascertain a score every eight hours and 36 % have no facility for standardized documentation in the records. At intensive care rounds, a possible diagnosis of delirium is an inherent part in only 34.9 % of the responders even with guideline knowledge. The particular gold standard for the therapy of delirium (alphaagonists for vegetative symptoms; 89.6 %, benzodiazepines for anxiety, 77.5 %; antipsychotics in 86.7 % for psychotic symptoms) is implemented more often with growing knowledge of the guidelines. The latter applies to the implementation of structured programs for delirium prophylaxis, cognition and therapy.

CONCLUSION

For the first time, this study documents knowledge and implementation of the German S3 guidelines for delirium in intensive care. Overall, the guidelines for delirium care are less well executed than those for sedation. With growing knowledge of the guidelines, diagnosis and treatment of delirium fits the guidelines more frequently. The facility to document a delirium score in intensive records is insufficient. Especially a nursing-based delirium strategy could possibly improve implementation of the guidelines, claiming an eight-hour screening and documentation. However, the small number of hospitals that have integrated the guidelines into in-house standard operating procedures (40 %) shows urgent need for optimization. A re-evaluation involving all relevant caretakers could probably improve the implementation of guidelines in intensive care and perioperative medicine.

Perceptions about the relative importance of patient care-related topics: a single institutional survey of its anesthesiologists, nurse anesthetists, and surgeons

Background

Persistently variable success has been experienced in locally translating even well-grounded national clinical practice guidelines, including in the perioperative setting. We have sought greater applicability and acceptance of clinical practice guidelines and protocols with our novel Perioperative Risk Optimization and Management Planning Tool (PROMPT™). This study was undertaken to survey our institutional perioperative clinicians regarding (a) their qualitative recommendations for (b) their quantitative perceptions of the relative importance of a series of clinical issues and patient medical conditions as potential topics for creating a PROMPT™.

Methods

We applied a mixed methods research design that involved collecting, analyzing, and “mixing” both qualitative and quantitative methods and data in a single study to answer a research question. Survey One was qualitative in nature and asked the study participants to list as free text up to 12 patient medical conditions or clinical issues that they perceived to be high priority topics for development of a PROMPT™. Survey Two was quantitative in nature and asked the study participants to rate each of these 57 specific, pre-selected clinical issues and patient medical conditions on an 11-point Likert scale of perceived importance as a potential topic for a PROMPT™. The two electronic, online surveys were completed by participants who were recruited from the faculty in our Department of Anesthesiology and Perioperative Medicine and Department of Surgery, and the cohort of hospital-employed certified registered nurse anesthetists.

Results

A total of 57 possible topics for a PROMPT™ was created and prioritized by our stakeholders. A strong correlation (r = 0.82, 95 % CI: 0.71, 0.89, P < 0.001) was observed between the quantitative clinician survey rating scores reported by the anesthesiologists/certified registered nurse anesthetists versus the surgeons. The quantitative survey displayed strong inter-rater reliability (ICC = 0.92, P < 0.001).

Conclusions

Our qualitative clinician stakeholder survey generated a comprehensive roster of clinical issues and patient medical conditions. Our subsequent quantitative clinician stakeholder survey indicated that there is generally strong agreement among anesthesiologists/certified registered nurse anesthetists and surgeons about the relative importance of these clinical issues and patient medical conditions as potential topics for perioperative optimization and risk management.

Perioperative Surgical Home: Perspective II

Healthcare delivery and payment systems in the United States must continue to be reformed to address currently untenably increasing healthcare expenditures, while increasing the quality of care. The Perioperative Surgical Home is a highly patient-centered approach to care, focusing on the standardization, coordination, transitions, and value of care, throughout the perioperative continuum, including after hospital discharge. To increase the value of surgical care, any Perioperative Surgical Home model must translate, implement, and sustain improvements in quality, safety, and satisfaction, plus cost reduction strategies, throughout the perioperative continuum. Healthcare informatics, analytics, decision support, and practice change are central to this effort.

Improved patient education facilitates adherence to preoperative fasting guidelines

Preoperative fasting is recognised as an important factor in perioperative patient care. Implementation of guidelines on preoperative fasting remains sub-optimal. We audited perioperative fasting in a district general hospital, implemented changes to the preoperative information leaflet and improved fasting practices. The manner in which information is presented to patients impacts behavior and adherence to recommendations. Improving this domain of clinical practice requires thorough and conscious effort and repeated reassessment.

Challenges of disseminating clinical practice guidelines in a weak health system: the case of HIV and infant feeding recommendations in Tanzania

BACKGROUND

Clinical guidelines aim to improve patient outcomes by providing recommendations on appropriate healthcare for specific clinical conditions. Scientific evidence produced over time leads to change in clinical guidelines, and a serious challenge may emerge in the process of communicating the changes to healthcare practitioners and getting new practices adopted. There is very little information on the major barriers to implementing clinical guidelines in low-income settings. Looking at how continual updates to clinical guidelines within a particular health intervention are communicated may shed light on the processes at work. The aim of this paper is to explore how the content of a series of diverging infant feeding guidelines have been communicated to managers in the Prevention of Mother to Child Transmission of HIV Programme (PMTCT) with the aim of generating knowledge about both barriers and facilitating factors in the dissemination of new and updated knowledge in clinical guidelines in the context of weak healthcare systems.

METHODS

A total of 22 in-depth interviews and two focus group discussions were conducted in 2011. All informants were linked to the PMTCT programme in Tanzania. The informants included managers at regional and district levels and health workers at health facility level.

RESULTS

The informants demonstrated partial and incomplete knowledge about the recommendations. There was lack of scientific reasoning behind various infant feeding recommendations. The greatest challenges to the successful communication of the infant feeding guidelines were related to slowness of communication, inaccessible jargon-ridden English language in the manuals, lack of summaries, lack of supportive supervision to make the guidelines comprehensible, and the absence of a reading culture.

CONCLUSION

The study encountered substantial gaps in knowledge about the diverse HIV and infant feeding policies. These gaps were partly related to the challenges of communicating the clinical guidelines. There is a need for caution in assuming that important changes in guidelines for clinical practice can easily be translated to and implemented in local programme settings, not least in the context of weak healthcare systems.

[Preoperative fasting guidelines: an update]

Anesthesiology societies have issued various guidelines on preoperative fasting since 1990, not only to decrease the incidence of lung aspiration and anesthetic morbidity, but also to increase patient comfort prior to anesthesia. Some of these societies have been updating their guidelines, as such that, since 2010, we now have 2 evidence-based preoperative fasting guidelines available. In this article, an attempt is made to review these updated guidelines, as well as the current instructions for more controversial patients such as infants, the obese, and a particular type of ophthalmic surgery.

Preoperative management of antiplatelet drugs for a coronary artery stent: how can we hit a moving target?

Background

With the advent of percutaneous coronary intervention, specifically the bare metal stent and subsequently, the drug-eluting stent, the scope of interventional cardiology has greatly increased. Aspirin, in combination with a thienopyridine is the present-day cornerstone of oral antiplatelet therapy after coronary artery stent placement. Continuing this chronic antiplatelet therapy, to mitigate a perioperative major adverse cardiac event, can be challenging and remains controversial in patients with a coronary artery stent undergoing non-cardiac surgery. We describe here the rationale for and successful use of an alternate approach to formulating local institutional management protocols for patients with a coronary artery stent, undergoing an elective surgical procedure.

Discussion

A recent systematic review identified 11 clinical practice guidelines for the perioperative management of antiplatelet therapy in patients with a coronary stent who need non-cardiac surgery. However, there is significant variance and inadequacy with these current applicable professional society guidelines. Moreover, persistently variable success has been experienced in translating even well-grounded national clinical guidelines into local practice, including in the perioperative setting. Under the auspices of a broadly multidisciplinary institutional task force and applying the Consensus-Oriented Decision-Making model, we created two evidence-informed and local expert opinion-supported standardized clinical assessment and management plans for the preoperative management of antiplatelet therapy in patients with a coronary artery stent.

Summary

Patient care can be optimized via evidence-based, yet locally developed and reiterative standardized clinical assessment and management plans for patients with coronary artery stents undergoing surgical procedures. Such standardized clinical assessment and management plans can result in greater consistency in care, providing a positive feedback loop in which the care plan itself can be continuously reevaluated, improved, and brought up to date with the most recent available data and knowledge.

Pediatric fasting times before surgical and radiologic procedures: benchmarking institutional practices against national standards

Prolonged preoperative fasting can be associated with adverse outcomes, particularly in children. Our aims were to assess the time pediatric patients fasted prior to surgical or radiologic procedures and evaluate whether fasting (NPO) orders complied with national guidelines. We measured NPO start time, time of last intake, and time test or surgery was scheduled, took place, or was cancelled in 219 pediatric patients. Findings demonstrate that pediatric patients experienced prolonged fasting before procedures and that the majority of NPO orders were non-compliant with national guidelines. We have developed strategies to reduce fasting times and ensure compliance with recommended national fasting standards.

Standard operating procedure changed pre-hospital critical care anaesthesiologists' behaviour: a quality control study

Introduction

The ability of standard operating procedures to improve pre-hospital critical care by changing pre-hospital physician behaviour is uncertain. We report data from a prospective quality control study of the effect on pre-hospital critical care anaesthesiologists’ behaviour of implementing a standard operating procedure for pre-hospital controlled ventilation.

Materials and methods

Anaesthesiologists from eight pre-hospital critical care teams in the Central Denmark Region prospectively registered pre-hospital advanced airway-management data according to the Utstein-style template. We collected pre-intervention data from February 1^st 2011 to January 31^st 2012, implemented the standard operating procedure on February 1^st 2012 and collected post intervention data from February 1^st 2012 until October 31^st 2012. We included transported patients of all ages in need of controlled ventilation treated with pre-hospital endotracheal intubation or the insertion of a supraglottic airways device. The objective was to evaluate whether the development and implementation of a standard operating procedure for controlled ventilation during transport could change pre-hospital critical care anaesthesiologists’ behaviour and thereby increase the use of automated ventilators in these patients.

Results

The implementation of a standard operating procedure increased the overall prevalence of automated ventilator use in transported patients in need of controlled ventilation from 0.40 (0.34-0.47) to 0.74 (0.69-0.80) with a prevalence ratio of 1.85 (1.57-2.19) (p = 0.00). The prevalence of automated ventilator use in transported traumatic brain injury patients in need of controlled ventilation increased from 0.44 (0.26-0.62) to 0.85 (0.62-0.97) with a prevalence ratio of 1.94 (1.26-3.0) (p = 0.0039). The prevalence of automated ventilator use in patients transported after return of spontaneous circulation following pre-hospital cardiac arrest increased from 0.39 (0.26-0.48) to 0.69 (0.58-0.78) with a prevalence ratio of 1.79 (1.36-2.35) (p = 0.00).

Conclusion

We have shown that the implementation of a standard operating procedure for pre-hospital controlled ventilation can significantly change pre-hospital critical care anaesthesiologists’ behaviour.

Too complicated for the field? Measuring quality of care in humanitarian aid settings

While quality of care is a major concern in the western world, not many studies investigate this topic in low-income countries. Even less is known about the quality of care in humanitarian aid settings, where additional challenges from natural or manmade disasters contribute to additional challenges. This study tried to address this gap by introducing a new approach to systematically measure quality of care in a project of Médecins Sans Frontières (MSF) in Agok area, between South Sudan and Sudan. Our objective was to obtain a valid snapshot of quality of care for a MSF project in three weeks that has the potential to serve as a baseline for quality improvement strategies. The evaluation followed a cross-sectional study design to assess structural, process and outcome quality according to Donabedian's criteria of quality of care. A bundle of well-established methods for collection of quantitative and qualitative data was used to assess the project by following a triangulated mixed-methods approach. Mean structural quality scored 73% of expected performance level and mean process quality 59%. The overall mortality rate for the hospital was 3.6%. On average, less complicated cases got a better level of care than patients who were seriously ill. Significant motivational issues were discovered in staff interviews potentially affecting quality of care. The tool appeared to be quick, feasible and effective in judging quality of care in the selected project. To tap the whole potential of the approach a re-evaluation should be carried out to assess the effectiveness of implemented improvement strategies in Agok. To confirm the usefulness of the approach, more studies are needed covering the variety of different humanitarian aid settings.

[Patient safety in anesthesiology and intensive care medicine. Measures for improvement]

Technical improvements as well as various strategies for error detection and error prevention have made intensive care medicine and anesthesiology a safe medical specialty. Due to the introduction of "Patient safety in the ICU: the Vienna declaration" of the European Society of Intensive Care Medicine (ESICM) from October 2009 and the "Helsinki declaration on patient safety" of the European Society of Anaesthesiology (ESA) and the European Board of Anaesthesiology (EBA) from June 2010, there are now specific recommendations for all hospitals in Europe concerning the safety measures that are considered to be of essential importance. Many of today's well-known safety strategies have been originally developed in non-medical environments, as for instance civil aviation. Such high reliability organizations may serve as examples in the medical domain. Critical incident reporting systems, crisis resource management and checklists, e.g. the World Health Organization (WHO) checklist, are safety approaches of this kind. In addition to these, standardized drug labelling, hand disinfection, techniques for patient handover and simulation-based training have been exemplarily selected for this article as measures that can increase patient safety.

The perioperative management of patients with coronary artery stents: surveying the clinical stakeholders and arriving at a consensus regarding optimal care

BACKGROUND

The perioperative management of patients with a coronary artery stent is a major patient safety issue currently confronting clinicians. Surgery on a patient on antiplatelet therapy creates the following dilemma: is it better to withdraw the drugs and reduce the hemorrhagic risk or to maintain them and reduce the risk of a myocardial ischemic event?

METHODS

An electronic survey was used to sample a cross-section of local clinicians regarding the perioperative management of patients with an indwelling coronary artery stent. The reiterative Consensus-Oriented Decision-Making model was applied by an institutional task force with representation from anesthesiology, cardiology, primary care medicine, and surgery.

RESULTS

Significant disagreement existed among the multidisciplinary survey respondents regarding various aspects of the perioperative management of patients with indwelling coronary artery stents.

CONCLUSIONS

We clarified the perioperative risk factors for coronary stent thrombosis and an alternate process for immediate access to a cardiac catheterization laboratory at our institution.

Development and assessment of indicators for quality of care in severe preeclampsia/eclampsia and postpartum hemorrhage

Severe preeclampsia/eclampsia and postpartum hemorrhage (PPH) are serious obstetric problems worldwide. Quality improvement of care measured by evidence-based indicators is recommended as a recent important strategy; however, the indicators for quality of care of these two conditions have not been established. This study aimed to develop such indicators and assess their validity, reliability, and feasibility at different contextual levels. Of 32 initially valid indicators for care of severe preeclampsia/eclampsia, after two rounds of Delphi technique, 21 and 30 indicators were agreed to be suitable to monitor care at district and referral hospitals. Of 13 initial indicators for PPH, 8 and 13 indicators were selected, respectively. The interrater reliability of indicators varied from 0.28 to 0.63. At least three-fourths of all indicators rated by local doctors and nurses were assessed as feasible in terms of relevance, measurability, and improvability. The process identified reliable and feasible performance indicators to monitor quality of care in severe preeclampsia/eclampsia and PPH for either basic or comprehensive emergency obstetric care (EmOC). The informative applicability of these indicators in clinical practice needs further evaluation.

Preoperative fasting: will the evidence ever be put into practice?

OVERVIEW

Decades of research support the safety and health benefits of consuming clear liquids, including those that are carbohydrate rich, until a few hours before elective surgery or other procedures requiring sedation or anesthesia. Still, U.S. clinicians routinely instruct patients to fast for excessively long preoperative periods. Evidence-based guidelines, published over the past 25 years in the United States, Canada, and throughout Europe, recommend liberalizing preoperative fasting policies. To improve patient safety and health care quality, it's essential that health care professionals abandon outdated preoperative fasting policies and allow available evidence to guide preanesthetic practices.

Preconditions for successful guideline implementation: perceptions of oncology nurses

Background

Although evidence-based guidelines are important for improving the quality of patient care, implementation in practice is below expectations. With the recent focus on team care, guidelines are intended to promote the integration of care across multiple disciplines. We conducted an exploratory study to understand oncology nurses' perceptions of guideline implementation and to learn their views on how their experiences affected the implementation.

Methods

A qualitative study was used with focus group interviews. We collected data from 11 nurses with more than 5 years of oncology nursing experience in Japan. The data were analyzed using grounded theory.

Results

Results of the analysis identified "preconditions for successful guideline implementation" as a core category. There were 4 categories (goal congruence, equal partnership, professional self-development and user-friendliness) and 11 subcategories related to organizational, multidisciplinary, individual, and guideline levels.

Conclusions

Although the guidelines were viewed as important, they were not fully implemented in practice. There are preconditions at the organizational, multidisciplinary, individual, and guideline levels that must be met if an organization is to successfully implement the guideline in clinical settings. Prioritizing strategies by focusing on these preconditions will help to facilitate successful guideline implementation.

Nutritional therapy in patients with acute pancreatitis requiring critical care unit management: a prospective observational study in Australia and New Zealand

OBJECTIVE

To determine nutritional therapy practices of patients with severe acute pancreatitis (defined as those receiving critical care management in an intensive care unit or high-dependency unit) in Australia and New Zealand with focus on the choice of enteral nutrition or parenteral nutrition.

DESIGN

Prospective observational multicentered study performed at 40 sites in Australia and New Zealand over 6 months.

SETTING

Intensive care units or high-dependency units within Australia and New Zealand.

PATIENTS

Those with severe acute pancreatitis diagnosed by elevated lipase and/or amylase. Patients with chronic pancreatitis were excluded.

MEASUREMENTS

The primary outcome was the proportion of patients who received enteral nutrition, parenteral nutrition, or concurrent enteral nutrition/parenteral nutrition. Secondary outcomes included other aspects of nutritional therapy and the severity and clinical outcomes of acute pancreatitis.

MEASUREMENTS AND MAIN RESULTS

We enrolled 121 patients and 117 were analyzed. The mean age was 61 (sd 17) years and 53% were men. Enteral nutrition was delivered to 58 (50%; 95% confidence interval [CI], 41-59%) and parenteral nutrition to 49 (42%; 95% CI, 33-51%) patients. Parenteral nutrition was more frequently used as the initial therapy (58%; 95% CI, 49-67%) than enteral nutrition (42%; 95% CI, 33-51%). The most common reason for parenteral nutrition prescription was the treating doctor's preference (60%). Enteral nutrition (74%) was more often used than parenteral nutrition (40%) on any individual study day. Concurrent enteral nutrition and parenteral nutrition occurred in 28 (24%) patients on 14% of days. Complications of acute pancreatitis requiring critical care unit management were observed in 45 (39%) patients. The median (interquartile range) duration of intensive care unit and hospital stay were 5 (2-10) and 19 (9-31) days, respectively. The hospital mortality rate was 15% (95% CI, 8-21%), and there was a tendency toward higher mortality for patients who only received parenteral nutrition than for those who only received enteral nutrition (28% vs. 7%, p=.06).

CONCLUSIONS

For patients with acute pancreatitis requiring critical care unit management in Australian and New Zealand intensive care units, enteral nutrition is used most commonly, but parenteral nutrition is more often used as the initial route of nutritional therapy. Given that clinical practice guidelines currently recommend enteral nutrition as the initial route of nutritional therapy in severe acute pancreatitis, improved education about and dissemination of these guidelines seems warranted.

Adherence to Guideline-Based Standard Operating Procedures in Pre-Hospital Emergency Patients with Chronic Obstructive Pulmonary Disease

This study investigated improvements in pre-hospital care for patients with acute exacerbated chronic obstructive pulmonary disease (aeCOPD) achieved by using a standard operating procedure (SOP). An SOP for pre-hospital treatment of patients with aeCOPD was designed based on valid national guidelines. A total of 1000 Emergency Medical Service patient care reports were analysed prospectively: 500 before and 500 after introduction of the SOP. Overall guideline adherence was 34.6% before and 53.8% after introduction of the SOP; this increase was not statistically significant. After SOP introduction, the administration of β2-mimetics by inhalative, intravenous and subcutaneous routes increased significantly. The level of knowledge of the national guidelines was rated at 67% by emergency physicians during self-assessment, but was only 33% when physicians were asked specific questions during interview. Introducing the SOP for patients with aeCOPD did not significantly improve adherence to valid national guidelines, but did help to improve specific elements of therapy.

Pre-operative fasting: a nationwide survey of German anaesthesia departments

BACKGROUND

Shorter pre-operative fasting improves clinical outcome without an increased risk. Since October 2004, German Anaesthesiology Societies have officially recommended a fast of 2 h for clear fluids and 6 h for solid food before elective surgery. We conducted a nationwide survey to evaluate the current clinical practice in Germany.

METHODS

Between July 2006 and January 2007, standardized questionnaires were mailed to 3751 Anaesthesiology Society members in leading positions requesting anonymous response.

RESULTS

The overall response rate was 66% (n=2418). Of those, 2148 (92%) claimed familiarity with the new guidelines. About a third (n=806, 34%) reported full adherence to the new recommendations, whereas 1043 (45%) reported an eased fasting practice. Traditional Nil per os after midnight was still recommended by 157 (7%). Commonest reasons reported for adopting the new guidelines were: 'improved pre-operative comfort' (84%), and 'increased patient satisfaction' (83%); reasons against were: 'low flexibility in operation room management' (19%), and 'increased risk of aspiration' (13%).

CONCLUSION

Despite the apparent understanding of the benefits from reduced pre-operative fasting, full implementation of the guidelines remains poor in German anaesthesiology departments.

A conditional model of evidence-based decision making

RATIONALE, AIMS AND OBJECTIVES

Efforts to describe how individual treatment decisions are informed by systematic knowledge have been hindered by a standard that gauges the quality of clinical decisions by their adherence to guidelines and evidence-based practices. This paper tests a new contextual standard that gauges the incorporation of knowledge into practice and develops a model of evidence-based decision making. Previous work found that the forecasted outcome of a treatment guideline exerts a highly significant influence on how it is used in making decisions. This study proposed that forecasted outcomes affect the recognition of a treatment scenario, and this recognition triggers distinct contextual decision strategies.

METHODS

Twenty-one volunteers from a psychiatric residency programme responded to 64 case vignettes, 16 in each of the four treatment scenarios. The vignettes represented a fully balanced within-subjects design that included guideline switching criteria and patient-specific factors. For each vignette, participants indicated whether they endorsed the guideline's recommendation.

RESULTS

Clinicians used consistent contextual decision strategies in responding to clearly positive or negative forecasts. When forecasts were more ambiguous or risky, their strategies became complex and relatively inconsistent.

CONCLUSION

The results support a three-step model of evidence-based decision making, in which clinicians recognize a decision scenario, apply a simple contextual strategy, then if necessary engage a more complex strategy to resolve discrepancies between general guidelines and specific cases. The paper concludes by noting study limitations and discussing implications of the model for future research in clinical and shared decision making, training and guideline development.

Post-cardiac arrest syndrome: Epidemiology, pathophysiology, treatment, and prognostication: A scientific statement from the International Liaison Committee on Resuscitation; the American Heart Association Emergency Cardiovascular Care Committee; the Council on Cardiovascular Surgery and Anesthesia; the Council on Cardiopulmonary, Perioperative, and Critical Care; the Council on Clinical Cardiology; the Council on Stroke (Part 1)

AIM OF THE REVIEW

To review the epidemiology, pathophysiology, treatment and prognostication in relation to the post-cardiac arrest syndrome.

METHODS

Relevant articles were identified using PubMed, EMBASE and an American Heart Association EndNote master resuscitation reference library, supplemented by hand searches of key papers. Writing groups comprising international experts were assigned to each section. Drafts of the document were circulated to all authors for comment and amendment.

RESULTS

The 4 key components of post-cardiac arrest syndrome were identified as (1) post-cardiac arrest brain injury, (2) post-cardiac arrest myocardial dysfunction, (3) systemic ischaemia/reperfusion response, and (4) persistent precipitating pathology.

CONCLUSIONS

A growing body of knowledge suggests that the individual components of the postcardiac arrest syndrome are potentially treatable.

Preoperative fasting duration and medication instruction: are we improving?

Research has shown that preoperative fasting practices commonly are much longer than national guidelines, and medication instructions are not always given to patients before surgery. After implementation of an evidence-based preoperative fasting policy and educational efforts for health care providers at one facility, a follow up project was conducted to determine whether these efforts had improved fasting practices. The project findings indicate that preoperative fasting in excess of safe minimum guidelines persists. Improvements were found in the percentage of patients receiving specific instructions about whether to take their routine medications on the morning of surgery. Continued efforts must be made to implement best practices for preoperative fasting.
