Summary Pain is a presenting symptom in 70% of visits to an emergency department. Severe pain can lead to deterioration of physiological symptoms and considerable anxiety and stress when left untreated. However, inadequate management of pain (oligoanalgesia) is a well-recognised phenomenon within the emergency department. Despite a number of suggested reasons for oligoanalgesia, there is a lack of empirical research investigating the factors are associated with good pain management and reasons for differences in pain management between emergency departments. This research proposes to address this research gap using a mixed methods approach. A systematic review of interventions to improve pain management and evidence synthesis of factors affecting pain management within the emergency department will be undertaken to identify effective interventions and examine the context in which these interventions work. Case studies of emergency departments will be undertaken to identify factors affecting pain management and to understand how pain is managed differently between departments and with different patient groups, providing empirical evidence to complement existing literature. Evidence from the synthesis and case studies will be used to identify factors associated with good pain management and a national survey of emergency departments will be undertaken to identify the prevalence of these factors and seek information around the willingness to implement changes. Background Pain is the most common reason for seeking healthcare and is a presenting complaint in around 70% of visits to an emergency department 1, 2, 3. The emergency department is responsible for treating patients with trauma-related pain, other acute pain (e.g. abdominal pain, headache) and also has a role in the treatment of patients with pain due to chronic disease and terminal illness. Although pain may be viewed as a temporary experience, acute pain can trigger a number of physiological responses and have a significant negative impact on patients. Examples of responses include pressure upon the cardiovascular and respiratory systems (e.g. increased breathing and heart rates), temporarily impaired gastrointestinal function and depression of the immune system, as well as negative psychological and cognitive effects 4. Untreated episodes of acute pain can lead to further episodes of pain or debilitating chronic pain syndromes and aggressive behaviour 5,6.. Management of pain is therefore an essential part of the duty of care within an emergency department and recognition and treatment of pain should be a priority7. Pain management is seen as an important quality indicator and has been shown to correlate with patient satisfaction with the emergency department 8, 9. However, inadequate pain management (oligoanalgesia) resulting from inadequate prescribing or delay in prescribing analgesia in the emergency department has long been recognised as a significant problem globally 10, 11. Studies from emergency departments in Europe, America and Canada suggest that over 50% of patients leave the department in significant or severe pain12, 13. In the UK, a Healthcare Commission (HCC) survey recently criticised pain management in UK emergency departments14. There are many potential explanations for the degree of oligoanalgesia within the emergency department. Culturally, pain management in the emergency department has historically not been a priority. There is an inherent conflict between the goal of speedy diagnosis and subsequent treatment required and the relatively time-consuming process of assessing, treating and monitoring patient pain levels whilst in the department, particularly if pain is considered a symptom rather than a physiology in itself 6, 10. The lack of relationship between the doctor and patient within the emergency department has also been suggested as problematic, particularly as the nature of emergency care work necessitates a level of detachment and tolerance for suffering that may be higher than in other disciplines 6. Pain is a subjective concept which can only be assessed using patient-reported measures and is also open to subjective judgements from the clinician interpreting these measures. Clinical judgement can be affected by many factors such as inadequate knowledge of pain relief, requirement of tangible proof of pain and a lack of belief of the patient’s assessment of pain 10. As a result, the assessment of patients with cognitive impairment or communication problems is particularly difficult and potentially worse within the emergency department as trauma or stress can impact upon an individual’s ability to communicate6. The subjectivity of assessment of pain may be reflected in evidence that patient factors such as triage category, gender, ethnic origin and age can have an impact upon levels of analgesia prescribing within the emergency department 15, 16, 17. Despite oligoanalgesia being a well known phenomenon, few solutions have been proposed, although more studies looking at improving pain management in the emergency departments have appeared in recent years18, 12, 7. There have been a number of studies and reviews discussing potential barriers to pain management, focussing mainly on physician and cultural barriers. However, much of this work is speculative or has involved applying general learning around pain management from other contexts to the emergency department, rather than studying pain management within the emergency department to understand theories and practice specific to the emergency department. The lack of empirical research on facilitators or obstacles to pain management in the emergency department has been recognised 6. There is a particular lack of qualitative research around barriers and facilitators to pain management, and any existing research has been based upon factors identified outside the emergency department 20. Studies based specifically within the emergency department have focussed upon patient factors that are associated with poor provision of pain relief 3, 20. Recently, there have been a number of studies looking at interventions to improve pain management within the emergency department, such as the use of pain scales to improve the assessment of pain, protocols for administration of pain relief or patient or nurse-administered opioids18, 19, 21. These largely address subsets of patients (e.g. long bone fractures, chronic pain) and guidance on pain management may be specific to these patient groups. Various guidelines around pain management in emergency departments exist 7, 22 but modification of behaviour in response to these has been inadequate and the evidence base for creating effective policy guidance is still considered to be weak 23. Despite some level of improvement in pain management in emergency departments in recent years 24, there are still many unanswered questions regarding why so many patients leave the emergency department with unresolved pain and why such a significant proportion of patients feel that their requests for pain control have not been managed adequately. In the UK there is considerable variation in patient-reported levels of pain management between providers. In 2008 a national survey of emergency department patients found that 59% of patients felt that the staff had definitely done everything they could to help control their pain, with the proportion ranging from 41%-74% between emergency departments 24. In this same survey, 14% of people felt that staff did not even try to control their pain (range 4-26%). Although some of this variation may be due to differences in populations (older age, female gender and lower urgency triage codes have been associated with delay to analgesia), these figures were adjusted for age, sex and ethnicity which suggests that there are significant differences in the way pain is managed between departments. It is likely that these differences are due to a complex combination of organisational, professional and patient factors. Given that pain management is an acknowledged problem and that this is a significant issue in the quality of care within emergency departments, it is essential to understand which factors are associated with adequate pain management in order to improve the levels of pain management and decrease the variance in performance between departments. Interventions to improve pain management are more likely to be successful if they are based on a good theoretical understanding of the factors that influence pain management. The current lack of research in this area may contribute to the lack of effect from existing interventions to improve pain management. Aim: To explore ways of improving pain management within adult emergency departments in England and Wales and identify factors affecting pain management. More specifically this will involve: Reviewing existing literature around interventions for improving pain management and factors associated with pain management in emergency department. Investigating facilitators and barriers to improving pain management within emergency departments and reasons for differences between departments. In particular, identifying factors that can be modified within the constraints of different types of departments and for different groups of patients. Investigating the feasibility of introducing interventions to improve pain management within emergency departments Plan of investigation and timescales In order to address how to improve pain management in the adult emergency department, it is important to understand how pain is currently managed, what factors are associated with good pain management and whether those factors can be modified in poorly performing departments in order to improve pain management. This is a mixed methods study. Qualitative methods will be used to identify factors that may be associated with the quality of pain management, and potential barriers and facilitators to good pain management. This will enable the development of a quantitative survey that will be used to identify the prevalence of these factors and barriers. The research has three sequential phases: Phase 1: Systematic review and evidence synthesis (months 1-12) The first phase of the research will involve expanding a systematic review of interventions to improve pain management and the provision of pain relief within the emergency department and undertaking evidence synthesis of factors affecting pain management. A systematic review was undertaken within ScHARR of interventions to improve pain management in 2009 25. This will be updated and then extended to examine contexts in which any effective interventions work (e.g. patient condition, emergency department type). The evidence synthesis will identify patient, professional and organisational factors that affect pain management. A preliminary literature search identified a limited body of literature focussing mainly on patient factors. A systematic approach to synthesising existing literature will be taken 26. The systematic review and evidence synthesis will be updated throughout the course of the fellowship to ensure all recent evidence is included. The aim of this phase of the research is to provide an up-to-date understanding of the existing evidence so that the empirical research phases 2 and 3 can build upon the current knowledge base. Phase 2: Case studies (months 13-36) The second phase of the research is a multiple case study design of three emergency departments with different levels of pain management 27. This will involve a stepped approach, first understanding case studies in one emergency department with good pain management and an emergency department with recently improved pain management to identify patient, professional and organisational factors affecting pain management. Then a further case study of one emergency department with poorer levels of pain management will be undertaken to identify barriers and examine the feasibility of introducing successful interventions and facilitators identified within the evidence synthesis and earlier case studies. Much of the current literature around factors affecting pain management within the emergency department is based around research from contexts other than the emergency department. The indepth qualitative approach used in phase 2 is important because it will lead to a knowledge base grounded in the emergency department. Preliminary literature searches identified gaps in research in this area and it is hoped that data from the case studies will expand upon existing literature and fill some of the knowledge gaps in the area. Identification and recruitment of sites (months 1-12): The scores relating to pain management for every major adult emergency department in England and Wales from the Healthcare Commission Emergency Department survey 2004 and 2008 24 will be obtained from the Care Quality Commission (CQC), either directly from the Picker Institute who ran the survey or from individual Trust reports that are available on the website. This score was calculated for patients who were in pain upon their visit to emergency department and is based upon the responses to questions around time to analgesia and whether patients felt that staff had done everything they could to control their pain. These will be analysed to create a shortlist of emergency departments that performed consistently well, consistently poorly and sites that improved significantly in score over the period 2004-2008. Sites from each of these groups will be selected and invited to participate in the research, until 3 relevant emergency departments have agreed to participate. Undertaking case studies The case studies will involve collecting data from multiple sources: documentation, interviews, focus groups and direct observation 27. Qualitative interviews and focus groups are essential to understanding attitudes and processes of pain management from different perspectives. Observational work will help in understanding the roles of different staff and interactions between staff and patients, and will complement accounts given by interviewees 28. Documentation and records pertaining to pain management (e.g. pain management protocols, pain audits, use of pain measurement tools within notes) will be examined. Each site visit will involve an initial half-day of general observation to look at how pain is managed, processes and personnel involved, assessment of the layout of the department and understanding the patient journey for patients presenting with pain as a key symptom. Any direct observations of staff-staff and patient-staff interactions relating to pain management within the emergency department will be undertaken with as little intrusion as possible in order to minimise the impact of observer effect upon the interactions being observed. Semi-structured interviews will be carried out with a purposive sample of 8-12 staff at each site, including senior and junior clinical staff, nursing staff, managers and receptionists. Interviews will invite respondents to offer their own insights on how pain is managed and prioritised, including strategies used, barriers and facilitators, and differences between patient groups (e.g. pain due to fracture, chronic pain). Interviews with a maximum diversity sample of 10-15 patients per site will be carried out, either within the department directly following their discharge from the emergency department or by telephone at a later date. Criteria for patient selection will be driven by the findings of the literature review. These interviews will focus upon the patient’s experience of pain management and identify barriers or facilitators to pain management perceived by the patient. Following the interviews further focused observation will be undertaken. Findings about the pain management within the department will be fed back to a focus group of staff and patient representatives who will be asked to think about how to improve pain management within their department. Where interventions felt to be successful are in place (or identified as successful within the literature), the focus group will be asked to consider what makes these a success and whether the intervention could be applied to other contexts. In emergency departments where interventions are not used, or considered not to be working, the focus groups will be asked to consider the feasibility of implementing or improving interventions identified in the literature and perceived barriers to doing so. The aim is to conduct case studies first in a department which appears to have good pain management and those with improved pain scores in order to develop an understanding of what factors facilitate pain management and factors that have contributed to any improvement. These ideas will then be explored within focus groups in the site with poorer pain management. Although this research plans to identify “good” and “poor” departments, it is possible that these labels could turn out to be inappropriate. The HCC survey may not properly represent pain management, it may be confounded by other factors such as patient case mix, or it may not reflect the experiences of specific patient groups. These issues will be explored within interviews. Data collection will be undertaken over a period of around 6-7 days in each site in total, over 3-4 visits and will aim to cover a variety of time periods including in-and out of hours and weekends. Qualitative data will be analysed using framework analysis, including the stages of familiarisation, identification of a thematic framework, indexing, charting and mapping and interpretation of the data 29. Yin’s approach to multiple case study analysis will be used 27. Phase 3: Survey of emergency departments (months 37-48) A national survey of emergency departments will be undertaken to identify pain management interventions and strategies in use, the prevalence of factors affecting pain management identified within phases 1 and 2, the willingness to implement changes shown to be effective, and the barriers to effecting change. As well as offering an in-depth understanding of pain management in emergency departments, the data from the qualitative work will be analysed to generate hypotheses about factors associated with good pain management and barriers to improving pain management. These data, alongside information identified from the literature, will be used to develop a questionnaire for use in a survey testing the prevalence of these issues nationally. This postal survey will be sent out to the clinical lead in all major emergency departments in England and Wales (n=~200). The survey should achieve a high response rate (around 70%) with 2 reminder letters and telephone calls to non-responders 30 31. The department in which this fellowship will be based often undertakes surveys of emergency departments so the infrastructure required to send out surveys (i.e. database of contact details) is already in place. The questionnaire will consist of two parts. The first will ask about the existence of various factors relevant to pain management. This is likely to include questions around staff and organisational issues that arise (e.g. education and training in pain management), any interventions used or tested (e.g. use of pain monitoring tools, protocols) and use and perceptions of facilitators and barriers to good practice. The survey will seek information on how different subsets of patients are managed in order to identify areas where there is a need for further specific guidance and where pain management strategies are lacking. The second part of the survey will seek information on the willingness to implement changes or interventions identified within phases 1 and 2 and further details of any barriers to doing this. This survey will facilitate a greater understanding of factors associated with good pain management and will provide information as to the variation in how pain is managed between departments. Where possible, information will be obtained from routine data sources in order to minimise the length of the questionnaire (e.g. data around factors such as patient casemix, staffing levels etc). Development of pain management toolkit and proposed outputs (months 49-60) The findings of the study will be summarised and used to develop a pain management toolkit that will be distributed to emergency departments to promote good pain management. The main output of the study will be the impact upon practice and benefit for patients as a result of: identifying methods for improving pain management that are likely to be feasible and effective; identifying barriers to improved pain management and ways of overcoming these barriers; an improvement in pain management and patient experience. In addition to completing the PhD thesis, the research will also be presented at national and international conferences and seminars. Further potential publications include: updated literature review and evidence synthesis qualitative research from the case study sites the national survey; the current picture of pain management in emergency department a mixed methods publication bringing together the results of all three phases and providing recommendations for improving practice 32. It is hoped that the research will identify areas of further research needed in the area of pain management in the emergency department and provide the basis to apply for funding for developing and testing an intervention to improve pain management in emergency departments. Ethical approval (months 1-12) Ethical approval for undertaking the case studies and survey will be sought from a multicentre research ethics committee (MREC) at the start of the project. Upon approval from MREC, local research ethics approval and research governance approval will be sought from sites identified. Due to the timescales involved in seeking ethical and research governance approval, this will be undertaken concurrently with the evidence synthesis. Justification of importance of this research and its relevance to the NHS This research will provide information on how pain management can be improved within emergency departments in the NHS and will provide recommendations for overcoming common barriers to change. Pain management is an important quality indicator and is likely to play a part in performance indicators for emergency care. This research willl provide important information on the causes of oligoanalgesia and identify modifiable factors within the NHS and enable emergency departments to improve their quality of care. The research should generate good practice guidance for emergency departments and the qualitative case studies may enable emergency departments involved to improve the priority of pain management within their departments and help to improve their performance References 1.
