Patterns of regional variation of opioid prescribing in primary care in England: a retrospective observational study

BACKGROUNDnOpioids are a widely prescribed class of drug with potentially harmful short-term and long-term side effects. There are concerns about the amounts of these drugs being prescribed in England given that they are increasingly considered ineffective in the context of long-term non-cancer pain, which is one of the major reasons for their prescription.nnnAIMnTo assess the amount and type of opioids prescribed in primary care in England, and patterns of regional variation in prescribing.nnnDESIGN AND SETTINGnRetrospective observational study using publicly available government data from various sources pertaining to opioids prescribed in primary practice in England and Indices of Social Deprivation.nnnMETHODnOfficial government data were analysed for opioid prescriptions from August 2010 to February 2014. The total amount of opioid prescribed was calculated and standardised to allow for geographical comparisons.nnnRESULTSnThe total amount of opioid prescribed, in equivalent milligrams of morphine, increased (r = 0.48) over the study period. More opioids were prescribed in the north than in the south of England (r = 0.66, P<0.0001), and more opioids were prescribed in areas of greater social deprivation (r = 0.56, P<0.0001).nnnCONCLUSIONnLong-term opioid prescribing is increasing despite poor efficacy for non-cancer pain, potential harm, and incompatibility with best practice. Questions of equality of care arise from higher prescription rates in the north of England and in areas of greater social deprivation. A national registry of patients with high opioid use would improve patient safety for this high-risk demographic, as well as provide more focused epidemiological data regarding patterns of prescribing.

Can images of pain enhance patient–clinician rapport in pain consultations?

A variety of treatment outcomes in chronic pain are influenced by patient–clinician rapport. Patients often report finding it difficult to explain their pain, and this potential obstacle to mutual understanding may impede patient–clinician rapport. Previous research has argued that the communication of both patients and clinicians is facilitated by the use of pain-related images in pain assessments. This study investigated whether introducing pain-related images into pain assessments would strengthen various components of patient–clinician rapport, including relative levels of affiliation and dominance, and interpersonal coordination between patient and clinician behaviour. Videos of 35 pain assessments in which pain images were present or absent were used to code behavioural displays of patient and clinician rapport at fixed intervals across the course of the assessment. Mixed modelling was used to examine patterns of patient and clinician affiliation and dominance with consultation type (Image vs Control) as a moderator. When pain images were present, clinicians showed more affiliation behaviour over the course of the consultation and there was greater correspondence between the affiliation behaviour of patient and clinician. However, relative levels of patient and clinician dominance were unaffected by the presence of pain images in consultations. Additional analyses revealed that clinicians responded directly to patients’ use of pain images with displays of affiliation. Based on the results of this study, we recommend further investigation into the utility and feasibility of incorporating pain images into pain assessments to enhance patient–clinician communication.

Mechanism evaluation of a lifestyle intervention for patients with musculoskeletal pain who are overweight or obese: protocol for a causal mediation analysis.

Introduction Low back pain (LBP) and knee osteoarthritis (OA) are highly prevalent and disabling conditions that cause societal and economic impact worldwide. Two randomised controlled trials (RCTs) will evaluate the effectiveness of a multicomponent lifestyle intervention for patients with LBP and knee OA who are overweight or obese. The key targets of this intervention are to improve physical activity, modify diet and correct pain beliefs. These factors may explain how a lifestyle intervention exerts its effects on key patient-relevant outcomes: pain, disability and quality of life. The aim of this protocol is to describe a planned analysis of a mechanism evaluation for a lifestyle intervention for overweight or obese patients with LBP and knee OA. Methods and analysis Causal mediation analyses of 2 two-armed RCTs. Both trials are part of a cohort-multiple RCT, embedded in routine health service delivery. In each respective trial, 160 patients with LBP and 120 patients with knee OA waiting for orthopaedic consultation will be randomised to a lifestyle intervention, or to remain part of the original cohort. The intervention consists of education and advice about the benefits of weight loss and physical activity, and the Australian New South Wales Get Healthy Service. All outcome measures including patient characteristics, primary and alternative mediators, outcomes, and potential confounders will be measured at baseline (T0). The primary mediator, weight, will be measured at 6 months post randomisation; alternative mediators including diet, physical activity and pain beliefs will be measured at 6 weeks post randomisation. All outcomes (pain, disability and quality of life) will be measured at 6 months post randomisation. Data will be analysed using causal mediation analysis with sensitivity analyses for sequential ignorability. All mediation models were specified a priori before completing data collection and without prior knowledge about the effectiveness of the intervention. Ethics and dissemination The study is approved by the Hunter New England Health Human Research Ethics Committee (13/12/11/5.18) and the University of Newcastle Human Research Ethics Committee (H-2015–0043). The results will be disseminated in peer-reviewed journals and at scientific conferences. Trial registration number ACTRN12615000490572 and ACTRN12615000478516; Pre-results.

The neglected role of distress in pain management: qualitative research on a gastrointestinal ward

Abstract Background and aims Pain management for hospital inpatients remains suboptimal. Previously identified barriers to optimal pain management include staff communication difficulties, confusion around pain management roles and a lack of suitable resources for clinical staff. The emotional, relational and contextual complexities of gastrointestinal (GI) pain create particular challenges for frontline clinical staff attempting to implement a biopsychosocial approach to its management. The current study took place over 2 years, comprised an ethnographic and a feedback phase, and aimed to examine pain management processes with clinical staff in order to generate hypotheses and initiatives for improvement. This paper focuses on two overarching themes identified in the ethnographic phase of the study, centred on the neglected role of both staff and patient distress in GI pain management. Methods Grounded theory and thematic analysis methods were used as part of action research, which involves collaborative working with clinical staff. The study took place on a 60 bed GI ward in a university hospital in London. Participants were clinical staff who were either ward-based or involved in the care of particular patients. This latter group included doctors, nurses, psychologists and physiotherapists from the Acute and Complex Pain Teams. Qualitative data on pain management processes was gathered from staff interviews, consultation groups, and observations of patient-staff interactions. Recruitment was purposive and collaborative in that early participants suggested targets and staff groups for subsequent enquiry. Following the identification of initial ethnographic themes, further analysis and the use of existing literature led to the identification of two overarching pain management processes. As such the results are divided into three sections: (i) illustration of initial ethnographic themes, (ii) summary of relevant theory used, (iii) exploration of hypothesised overarching processes. Results Initially, two consultation groups, five nursing staff and five junior doctors, provided key issues that were included in subsequent interviews (n=18) and observations (n=5). Initial ethnographic themes were divided into challenges and resources, reflecting the emergent structure of interviews and observations. Drawing on attachment, psychodynamic and evolutionary theories, themes were then regrouped around two overarching processes, centred on the neglected role of distress in pain management. The first process elucidates the lack of recognition during pain assessment of the emotional impact of patient distress on staff decision-making and pain management practice. The second process demonstrates that, as a consequence of resultant staff distress, communication between staff groups was fraught and resources, such as expert team referral and pharmacotherapy, appeared to function, at times, to protect staff rather than to help patients. Interpersonal skills used by staff to relieve patient distress were largely outside systems for pain care. Conclusions Findings suggest that identified “barriers” to optimal pain management likely serve an important defensive function for staff and organisations. Implications Unless the impact of patient distress on staff is recognised and addressed within the system, these barriers will persist.

Images as catalysts for meaning-making in medical pain encounters: a multidisciplinary analysis

The challenge for those treating or witnessing pain is to find a way of crossing the chasm of meaning between them and the person living with pain. This paper proposes that images can strengthen agency in the person with pain, particularly but not only in the clinical setting, and can create a shared space within which to negotiate meaning. It draws on multidisciplinary analyses of unique material resulting from two fine art/medical collaborations in London, UK, in which the invisible experience of pain was made visible in the form of co-created photographic images, which were then made available to other patients as a resource to use in specialist consultations. In parallel with the pain encounters it describes, the paper weaves together the insights of specialists from a range of disciplines whose methodologies and priorities sometimes conflict and sometimes intersect to make sense of each other’s findings. A short section of video footage where images were used in a pain consultation is examined in fine detail from the perspective of each discipline. The analysis shows how the images function as ‘transactional objects’ and how their use coincides with an increase in the amount of talk and emotional disclosure on the part of the patient and greater non-verbal affiliative behaviour on the part of the doctor. These findings are interpreted from the different disciplinary perspectives, to build a complex picture of the multifaceted, contradictory and paradoxical nature of pain experience, the drive to communicate it and the potential role of visual images in clinical settings.

A novel inpatient complex pain team: protocol for a mixed-methods evaluation of a single-centre pilot study

Introduction Complex pain is a debilitating condition that is responsible for low quality of life and significant economic impacts. Although best practice in the treatment of complex pain employs a multidisciplinary team, many patients do not have access to this care, leading to poor outcomes. Methods and analysis This study evaluates a novel inpatient complex pain team at a large London teaching hospital. A multidisciplinary pain team comprising specialist doctors, nurses, psychologists and physiotherapists was instituted for inpatients with complex pain who will undergo an intense and bespoke evidence-based programme which will then be integrated into the community. A mixed-methods evaluation will take place and patients will be recruited over the course of 1u2009year. A qualitative arm will interview 15 staff and 15 patients on recruitment and again 6u2009months later looking to compare and contrast the new pain team with past experiences of pain management. A quantitative arm will assess clinical outcomes using validated scoring tools. An economic evaluation will seek to evaluate the relative cost of the service by comparing healthcare costs before and after the intervention. Ethics and dissemination The study was categorised as a service evaluation, so formal ethical approval was not considered necessary. Participant recruitment began in January 2016 and the 1-year follow-up will end in November 2017. The results of this study will be published in 2018.

GaPP2, a multicentre randomised controlled trial of the efficacy of gabapentin for the management of chronic pelvic pain in women : study protocol

Introduction Chronic pelvic pain (CPP) affects more than 1u2009million UK women with associated healthcare costs of £158u2009million annually. Current evidence supporting interventions when no underlying pathology is identified is very limited and treatment is frequently inadequate. Gabapentin (a GABA analogue) is efficacious and often well tolerated in other chronic pain conditions. We have completed a successful pilot randomised controlled trial Gabapentin for Pelvic Pain 1 (GaPP1) and here describe the protocol for our definitive multicentre trial to assess the efficacy of gabapentin in the management of CPP in women Gabapentin for Pelvic Pain 2 (GaPP2). Methods and analysis We plan to perform a double-blind placebo-controlled randomised multicentre clinical trial, recruiting 300 women with CPP from up to 40 National Health Service hospitals within the UK. After randomisation, women will titrate their medication (gabapentin or placebo) over a 4-week period to a maximum of 2700u2009mg or placebo equivalent and will then maintain a stable dose for a 12-week period. Response to treatment will be monitored with validated questionnaires and coprimary outcome measures of average and worst pain scores will be employed. The primary objective is to test the hypothesis that treatment with gabapentin has the potential to provide an effective oral treatment to alleviate pain in women with CPP in the absence of any obvious pelvic pathology. Ethics and dissemination Ethical approval has been obtained from the Coventry and Warwick Research Ethics Committee (REC 15/WM/0036). Data will be presented at international conferences and published in peer-reviewed journals. We will make the information obtained from the study available to the public through national bodies and charities. Trial registration number ISRCTN77451762; Pre-results.

“If I speak English, what am I? I am full man, me”: Emotional impact and barriers for refugees and asylum seekers learning English:

Lack of proficiency in the language of the host country predicts distress among refugees, but many refugees and asylum seekers in the United Kingdom have less than functional English. This study examined how learning English affected refugees’ and asylum seekers’ lives, particularly their emotional wellbeing, to explore what factors, particularly psychological ones, facilitated or impeded their learning English. We recruited 16 refugees and asylum seekers from an inner-city National Health Service trauma service and from a charity providing one-to-one English classes. All participants were interviewed in English. Interview data were analysed using thematic analysis from a critical realist perspective. Interviewees provided consistent accounts of their efforts to learn English, integrated into often unsettled and difficult lives. The analysis generated six themes in two domains. The impact of learning English was mainly positive, associated with autonomy, sense of achievement, and aspirations. Barriers to learning English consisted of other problems affecting refugees’ capacity to learn, limited opportunities to speak English, and a sense of shame associated with perceived lack of English language competence. Findings highlight the need to provide adequate psychological support for refugees and asylum seekers learning English, recognising its importance in promoting both their integration in the UK and their individual psychological well-being.
