We Are All in This Together-Whole of Community Pain Science Education Campaigns to Promote Better Management of Persistent Pain

Persistent pain is a major public health issue-estimated to affect a quarter of the world's population. Public understanding of persistent pain is based on outdated biomedical models, laden with misconceptions that are contrary to best evidence. This understanding is a barrier to effective pain management. Thus, there have been calls for public health-based interventions to address these misconceptions. Previous pain-focussed public education campaigns have targeted pain beliefs and behaviours that are thought to promote recovery, such as staying active. However, prevailing pain-related misconceptions render many of these approaches counter-intuitive, at best. Pain Science Education improves understanding of 'how pain works' and has been demonstrated to improve pain and disability outcomes. Extending Pain Science Education beyond the clinic to the wider community seems warranted. Learning from previous back pain-focussed and other public health educational campaigns could optimise the potential benefit of such a Pain Science Education campaign. Pain Science Education-grounded campaigns have been delivered in Australia and the UK and show promise, but robust evaluations are needed before any firm conclusions on their population impact can be made. Several challenges exist going forward. Not least is the need to ensure all stakeholders are involved in the development and implementation of Pain Science Education public messaging campaigns. Furthermore, it is crucial that campaigns are undertaken through a health equity lens, incorporating underrepresented communities to ensure that any intervention does not widen existing health inequalities associated with persistent pain. PERSPECTIVE: Public misconceptions about pain are a significant public health challenge and a viable intervention target to reduce the personal, social, and economic burden of persistent pain. Adaptation of Pain Science Education, which improves misconceptions in a clinical setting, into the public health setting seems a promising approach to explore.

The prevalence of chronic pain in adolescents in Central Switzerland: A cross- sectional school-based study protocol

BACKGROUND

Chronic pain is associated with substantial personal suffering and societal costs and is a growing healthcare concern worldwide. While chronic pain has been extensively studied in adults, limited data exists on its prevalence and impact in adolescents. Understanding the prevalence and impact of chronic pain and pain beliefs in adolescents is crucial for developing effective prevention and treatment strategies. This study aims to estimate the prevalence, characteristics, and impact of chronic pain, and explore adolescents' knowledge and beliefs about pain.

METHODS

This is an observational cohort study of school-going adolescents aged 11 to 17 years in Central Switzerland. The study will estimate the point prevalence, characteristics (location, intensity, frequency, duration) and impact (PROMIS Pediatric Short Form v2.0 -Pain Interference Scale, PPIS) of chronic pain in school-going adolescents. We will also measure and investigate pupils' beliefs about pain (Concept of Pain Inventory (COPI)). Data will be collected through manual and digital self-report questionnaires and from participants in primary, secondary, and high schools between September 2023 and January 2024.

ANALYSES

The primary analyses will utilise descriptive statistics to estimate the point prevalence, characteristics, and impact of chronic pain. Secondary analyses will analyse associations and correlations between chronic pain, impact of pain and beliefs about pain.

OUTCOMES

This study will provide an estimate of the prevalence, characteristics and impact of chronic pain in adolescents in Central Switzerland and a measure of adolescents' understanding and beliefs about pain. In doing so, this study will provide insights into the scale of chronic pain as a public health concern. By understanding adolescents' pain beliefs and their influence on pain experience, this study can contribute to the development of educational approaches to enhance adolescents' knowledge and understanding of pain in order to optimise the prevention and treatment of chronic pain in adolescents. The findings may be useful to healthcare professionals and funders, policymakers, and researchers involved in the prevention, assessment, and treatment of pain in adolescents.

Translation, contextual adaptation, and reliability of the Danish Concept of Pain Inventory (COPI-Adult (DK)) - A self-reported outcome measure

OBJECTIVES

Pain is a growing concern globally, and an individual and societal burden. Pain science education (PSE) is a promising avenue for managing chronic pain, but targeted PSE is needed. The Concept of Pain Inventory for Adults (COPI-Adult) is a newly developed self-reported outcome measure aimed at targeting PSE. It is currently unavailable in Danish and has unknown reliability. The aims of this study were (1) to translate and contextually adapt to Danish and (2) to determine reliability in terms of test-retest reliability, internal consistency, and measurement error.

METHODS

Step (1) was as follows: a dual panel approach was used to translate, contextually adapt into a Danish version. Step (2) was follows: a heterogenic sample of Danish adults >18 years (n = 150) was included in the test-retest analysis, test interval between 7 and 14 days, both answered via REDCap-link. Based on COSMIN recommendations, the following reliabilities were estimated: the test-retest using intraclass correlation coefficient (ICC2.1) and internal consistency using Cronbach's alpha level. Measurement error in terms of standard error of measurement (SEM) and smallest detectable change (SDC) were calculated.

RESULTS

Step (1) was as follows: the first panel reached 100% consensus on the wording of the COPI-Adult (DK), with no alterations by the second panel. Step (2) was as follows: good to excellent test-retest reliability was found with ICC2.1 value (95% confidence interval) 0.88 (0.84-0.91), excellent internal consistency for the 13-item COPI-Adult (DK) with α = 0.939, SEM of 2.53, and SDC of 7.02.

DISCUSSION

The COPI-Adult (DK) was successfully translated and contextually adapted. It is a reliable questionnaire with excellent internal consistency. The COPI-Adult (DK) shows promise in research and clinical practice.

An evaluation of a one-day pain science education event in a high school setting targeting pain related beliefs, knowledge, and behavioural intentions

BACKGROUND

Persistent pain is a common condition affecting one in four UK adults. Public understanding of pain is limited. Delivering pain education within schools may improve public understanding in the longer term.

OBJECTIVE

To evaluate the impact of a one-day Pain Science Education (PSE) event on sixth form/high school students' pain beliefs, knowledge and behavioural intention.

METHODS

Exploratory, single-site, mixed-methods, single-arm study involving secondary school students ≥16 years old attending a one-day PSE event. Outcome measures included the Pain Beliefs Questionnaire (PBQ), Concepts of Pain Inventory (COPI-ADULT), a vignette to assess pain behaviours; and thematic analysis of semi-structured interviews.

RESULTS

Ninety (mean age 16.5 years, 74% female) of the 114 attendees, agreed to participate in the evaluation. PBQ scores improved on the Organic beliefs subscale [mean difference -5.9 (95% CI -6.8, -5.0), P < 0.01] and Psychosocial Beliefs subscale [1.6 (1.0, 2.2) P < 0.01]. The COPI-Adult revealed an improvement [7.1 (6.0-8.1) points, P < 0.01] between baseline and post intervention. Pain behavioural intentions improved post education for work, exercise, and bed rest related activities (p < 0.05). Thematic analysis of interviews (n = 3) identified increased awareness of chronic pain and its underpinning biology, beliefs that pain education should be widely available, and that pain management should be holistic.

CONCLUSIONS

A one-day PSE public health event can improve pain beliefs, knowledge and behavioural intentions in high school students and increase openness to holistic management. Future controlled studies are needed to confirm these results and investigate potential long-term impacts.

Online information on chronic pain in 3 countries: an assessment of readability, credibility, and accuracy

Objectives

To assess the readability, credibility, and accuracy of online information on chronic pain in Australia, Mexico, and Nepal.

Methods

We assessed Google-based websites and government health websites about chronic pain for readability (using the Flesch Kincaid Readability Ease tool), credibility (using the Journal of American Medical Association [JAMA] benchmark criteria and Health on the Net Code [HONcode]), and accuracy (using 3 core concepts of pain science education: (1) pain does not mean my body is damaged; (2) thoughts, emotions, and experiences affect pain; and (3) I can retrain my overactive pain system).

Results

We assessed 71 Google-based websites and 15 government websites. There were no significant between-country differences in chronic pain information retrieved through Google for readability, credibility, or accuracy. Based on readability scores, the websites were "fairly difficult to read," suitable for ages 15 to 17 years or grades 10 to 12 years. For credibility, less than 30% of all websites met the full JAMA criteria, and more than 60% were not HONcode certified. For accuracy, all 3 core concepts were present in less than 30% of websites. Moreover, we found that the Australian government websites have low readability but are credible, and the majority provided all 3 core concepts in pain science education. A single Mexican government website had low readability without any core concepts but was credible.

Conclusion

The readability, credibility, and accuracy of online information on chronic pain should be improved internationally to support facilitating better management of chronic pain.

Implementation of an online pain science education for chronic musculoskeletal pain in Brazilian public health system: protocol for a hybrid type III randomised controlled trial with economic evaluation

BACKGROUND

Although clinical practice guidelines recommend pain education as the first-line option for the management of chronic musculoskeletal pain, there is a lack of pain education programmes in healthcare. Thus, digital health programmes can be an effective tool for implementing pain education strategies for public health. This trial will aim to analyse the implementation and effectiveness outcomes of three online pain science education strategies in the Brazilian public health system (SUS) for individuals with chronic musculoskeletal pain.

METHODS

We will conduct a hybrid type III effectiveness-implementation randomised controlled trial with economic evaluation. We will include adult individuals with chronic musculoskeletal pain, recruited from primary healthcare in the city of Guarapuava, Brazil. Individuals will be randomised to three implementation groups receiving a pain science education intervention (EducaDor) but delivered in different modalities: group 1) synchronous online; group 2) asynchronous videos; and group 3) interactive e-book only. Implementation outcomes will include acceptability, appropriateness, feasibility, adoption, fidelity, penetration, sustainability, and costs. We will also assess effectiveness outcomes, such as pain, function, quality of life, sleep, self-efficacy, and adverse effects. Cost-effectiveness and cost-utility analyses will be conducted from the SUS and societal perspectives. The evaluations will be done at baseline, post-intervention (10 weeks), and 6 months.

DISCUSSION

This study will develop and implement a collaborative intervention model involving primary healthcare professionals, secondary-level healthcare providers, and patients to enhance self-management of chronic pain. In addition to promoting better pain management, this study will also contribute to the field of implementation science in public health by generating important insights and recommendations for future interventions.

Targeting Pain Science Education in Youth With Chronic Pain: What Are the Sticking Points for Youth and Their Parents?

OBJECTIVES

An important part of providing pain science education is to first assess baseline knowledge and beliefs about pain, thereby identifying misconceptions and establishing individually-tailored learning objectives. The Concept of Pain Inventory (COPI) was developed to support this need. This study aimed to characterize the concept of pain in care-seeking youth and their parents, to examine its clinical and demographic correlates, and to identify conceptual gaps.

MATERIALS AND METHODS

Following an initial interdisciplinary evaluation, a cohort of 127 youth aged 8 to 18 years, and their parents, completed a series of questionnaires.

RESULTS

Parents had slightly higher COPI scores than youth did, reflecting parents' greater alignment with contemporary pain science. The moderate positive association with older age among youth ( r =.32) suggests that COPI is sensitive to cognitive development and life experiences. Youth and parent COPI responses were weakly associated ( r =0.24), highlighting the importance of targeting the concept of pain in both groups. For both parents and youth, 'Learning about pain can help you feel less pain' was the least endorsed concept. This conceptual 'gap' is a key point of intervention that could potentially lead to greater engagement with multidisciplinary pain treatment.

DISCUSSION

The COPI appears useful for identifying conceptual gaps or 'sticking points'; this may be an important step to pre-emptively address misconceptions about pain through pain science education. Future research should determine the utility of COPI in assessing and treating youth seeking care for pain. The COPI may be a useful tool for tailoring pain science education to youth and their parents.

The concept of pain inventory for children: The reliability and validity study of the Turkish version

BACKGROUND AND PURPOSE

Pain experiences in childhood are very likely to be reflected in adulthood. The early evaluation of the concept of pain in children may eventually lead to. better patient outcomes in the future. Therefore, we aimed to culturally and developmentally adapt the Concept of Pain Inventory for Children (COPI) for Turkish children.

METHODS

This descriptive, correlational study was conducted with 239 post-operative children aged 8-12 years between June and December 2021. The research adhered to COSMIN guidelines. The data were collected using a descriptive information form and the COPI. Factor analysis, Cronbach's alpha, and item-total score analysis were used for the data analysis.

RESULTS

The resulting unidimensional scale consists of 12 items in Turkish. The scale explained 65% of the total variance. The exploratory factor analysis showed that the factor loadings of items ranged from 0.64 to 0.91. The confirmatory factor analysis showed that the factor loadings of items ranged from 0.66 to 0.92. Goodness of fit indexes were found to be as follows: Normed Fit Index >0.90; Incremental Fit Index >0.90; Comparative Fit Index >0.90; and the Root Mean Square Error of Approximation <0.08. The total Cronbach's alpha coefficient of the scale was 0.78 (reliable).

CONCLUSIONS

The 12-item Turkish translation of the COPI was deemed valid and reliable in 8-12-year-old children in a post-operative setting.

PRACTICE IMPLICATIONS

Evaluation of children's pain concepts during childhood may contribute to the identification of conceptual gaps for pain science education.

Pain science education for children living with and beyond cancer: Challenges and research agenda

Pain in children living with and beyond cancer is understudied and undertreated. Pain science education (PSE) is a conceptual change strategy facilitating patients' understanding of the biopsychosocial aspects of pain. Preliminary studies on the adaptation of PSE interventions to adults with and beyond cancer provide a foundation for pediatric research. PSE could help childhood cancer survivors experiencing persistent pain and pain-related worry after active treatment. PSE may also help children receiving cancer treatment, providing them with a foundation of adaptive pain beliefs and cognitions, and preparing them for procedural and treatment-related pain. We direct this paper toward pediatric oncology clinicians, policy makers, and researchers working with children living with and beyond cancer. We aim to (a) identify challenges in adapting PSE for children living with and beyond cancer, (b) offer possible solutions, and (c) propose research questions to guide the implementation of PSE for children living with and beyond cancer.

Assessing a child or adolescent with low back pain is different to assessing an adult with low back pain

In contrast to an assessment of an adult presenting with low back pain (LBP), clinicians should utilise different approaches when assessing children and adolescents presenting with LBP. Children are not 'little adults'. There are some unique pathologies that only occur in this age group: (i) serious pathologies include infection, fracture, child abuse and malignancy; (ii) growth-related pathologies include scoliosis, Scheuermann's disease, pars fracture and spondylolysis; and (iii) rheumatological conditions include juvenile idiopathic arthritis and ankylosing spondylitis. With changes in each child occurring physically, emotionally and socially, a clinician's knowledge of typical developmental milestones is essential to identify regression or delayed development. When listening to a child discuss their pain experience, a flexible structure should be implemented that gives the capacity to actively listen to a child's narrative (and that of their guardian) and to conduct an effective physical examination. This viewpoint also summarises the relationship between potential clinical diagnoses and key elements of a physical examination. Deciding on the type and timing of paediatric-specific physical examination tests requires unique child-centred considerations. Paediatric-specific outcome measures should be used but implemented pragmatically, with consideration regarding the time, complexity and pathology suspected. Systematic and rigorous approaches to both treatment planning and re-assessment are then proposed for the assessment of children and adolescents presenting with LBP.

Comparison between 2000 and 2018 on the reporting of statistical significance and clinical relevance in physiotherapy clinical trials in six major physiotherapy journals: a meta-research design

DESIGN

Meta-research.

OBJECTIVE

To compare the prevalence of reporting p values, effect estimates and clinical relevance in physiotherapy randomised controlled trials (RCTs) published in the years 2000 and 2018.

METHODS

We performed a meta-research study of physiotherapy RCTs obtained from six major physiotherapy peer-reviewed journals that were published in the years 2000 and 2018. We searched the databases Embase, Medline and PubMed in May 2019, and extracted data on the study characteristics and whether articles reported on statistical significance, effect estimates and confidence intervals for baseline, between-group, and within-group differences, and clinical relevance. Data were presented using descriptive statistics and inferences were made based on proportions. A 20% difference between 2000 and 2018 was regarded as a meaningful difference.

RESULTS

We found 140 RCTs: 39 were published in 2000 and 101 in 2018. Overall, there was a high prevalence (>90%) of reporting p values for the main (between-group) analysis, with no difference between years. Statistical significance testing was frequently used for evaluating baseline differences, increasing from 28% in 2000 to 61.4% in 2018. The prevalence of reporting effect estimates, CIs and the mention of clinical relevance increased from 2000 to 2018 by 26.6%, 34% and 32.8% respectively. Despite an increase in use in 2018, over 40% of RCTs failed to report effect estimates, CIs and clinical relevance of results.

CONCLUSION

The prevalence of using p values remains high in physiotherapy research. Although the proportion of reporting effect estimates, CIs and clinical relevance is higher in 2018 compared to 2000, many publications still fail to report and interpret study findings in this way.

The Concept of Pain Inventory for Adults (COPI-Adult): Assessing Knowledge and Beliefs Regarding Pain Science Education

OBJECTIVES

Assessing knowledge and beliefs regarding pain science can identify gaps and misconceptions. The Concept of Pain Inventory (COPI) was recently developed in children with the intent to guide targeted pain science education. We utilized the original COPI item pool to (1) develop a tool to assess an adult's concept of pain in a cohort who had not received pain science education, (2) evaluate its psychometric properties, (3) examine distribution of scores in a cohort of adults who had received pain science education, and (4) examine associations between scores and clinical variables.

MATERIALS AND METHODS

A total cohort of 627 adults were recruited through social media for an online survey. Initial development was conducted on those who had not received prior pain science education (n=125), then the COPI-Adult tool was tested in those who had received prior pain science education (n=502).

RESULTS

The resulting unidimensional 13-item COPI-Adult had acceptable internal consistency (α=0.78) and good test-retest reliability at 1 week (Intraclass Correlation Coefficient3,1=0.84 (95% confidence interval: 0.71-0.91). Higher COPI-Adult scores reflect greater alignment with contemporary pain science. COPI-Adult scores were correlated with revised Neurophysiology of Pain Questionnaire (rNPQ) scores and inversely correlated with average and current pain intensity, and pain interference. Adults who reported having received pain science education had significantly higher mean COPI-Adult scores than those who had not, and this difference exceeded the smallest detectable change.

DISCUSSION

The COPI-Adult is a brief questionnaire with promising psychometric properties to identify conceptual gaps or misconceptions to inform individualized pain science education.

Using Mediation Analysis to Understand How Treatments for Paediatric Pain Work: A Systematic Review and Recommendations for Future Research

Clinicians have an increasing number of evidence-based interventions to treat pain in youth. Mediation analysis offers a way of investigating how interventions work, by examining the extent to which an intermediate variable, or mediator, explains the effect of an intervention. This systematic review examined studies that used mediation analysis to investigate mechanisms of interventions on pain-relevant outcomes for youth (3–18 years) with acute or chronic pain, and provides recommendations for future mediation research in this field. We searched five electronic databases for clinical trials or observational longitudinal studies that included a comparison group and conducted mediation analyses of interventions on youth and assessed pain outcomes. We found six studies (N = 635), which included a total of 53 mediation models examining how interventions affect pain-relevant outcomes for youth. Five studies were secondary analyses of randomized controlled trials of psychological interventions for chronic pain; one was a longitudinal observational study of morphine for acute pain. The pain conditions studied were irritable bowel syndrome, functional abdominal pain, juvenile fibromyalgia, mixed chronic pain, and post-operative pain. Fourteen putative mediators were tested, of which three partially mediated treatment effect; seven did not significantly mediate treatment effect and four had mixed results. Methodological and reporting limitations were common. There are substantial gaps in the field with respect to investigating, and therefore understanding, how paediatric interventions work.

The Importance of Perceived Relevance: A Qualitative Evaluation of Patient's Perceptions of Value and Impact Following a Low-Intensity Group-Based Pain Management Program

Background and objectives: Limited evidence exists exploring perceptions of which aspects of a pain management program are perceived as valuable and impactful. The aim of this study was to explore patient beliefs about which aspects of a pain management program were valued and/or had perceived impact. Materials and Methods: One-on-one structured interviews were conducted with 11 adults three months after their completion of the Spark Pain Program at Westmead Hospital, Sydney, Australia. Concepts in the transcripts were inductively identified and explored, utilizing thematic analysis to better understand their relevance to the study aim. Results: Four themes emerged: (1) "The program overall was positive, but…"; (2) "I valued my improved knowledge and understanding of pain, but…"; (3) "I valued the stretching/relaxation/pacing/activity monitoring"; and (4) "I valued being part of a supportive and understanding group". Participants reported that they liked being treated as an individual within the group. A lack of perceived personal relevance of key messages was identified in some participants; it appears that patients in pain programs must determine that changes in knowledge, beliefs, and attitudes are personally relevant in order for the changes to have a significant impact on them. Conclusions: This study provides new insights into aspects of a pain management program that were perceived as valuable and impactful, areas that "missed the mark", and hypotheses to guide the implementation of service delivery and program redesign.

Something Else Going On? Diagnostic Uncertainty in Children with Chronic Pain and Their Parents

Diagnostic uncertainty, the perceived lack of an accurate explanation of the patient's health problem, remains relatively unstudied in children. This study examined the prevalence, familial concordance, and correlates of diagnostic uncertainty in children and their parents presenting to a multidisciplinary pain clinic in the United States. One hundred and twenty-six parents and 91 of their children (Mage = 13.93 years, range = 8-18 years) completed a brief three-item measure of diagnostic uncertainty, as well as measures of pain-related distress and functioning. Forty-eight percent of children and 37% of parents believed something else was going on with the child's pain that doctors had not found out about yet. Across the three items, 66%-77% of children and their parents agreed in their endorsement of diagnostic uncertainty. Parents who believed that something else was going on with their child's pain had children with higher avoidance of pain-related activities (F = 5.601, p = 0.020) and lower pain willingness (F = 4.782, p = 0.032). Neither parent nor child diagnostic uncertainty was significantly related to the child's pain-related functioning. Diagnostic uncertainty, particularly in parents, is relevant in the experience of pediatric chronic pain and warrants further investigation as both a risk factor and therapeutic target.

Prognostic factors for pain and functional disability in children and adolescents with persisting pain: A systematic review and meta-analysis

BACKGROUND AND OBJECTIVE

The aim of this study was to investigate prognostic factors for pain and functional disability in children and/or adolescents with persisting pain.

DATABASES AND DATA TREATMENT

To be included, studies had to be published, peer-reviewed prospective cohort studies of children and/or adolescents with persisting pain at baseline, that reported at least one baseline prognostic factor and its relationship with pain or functional disability at least 1 month after baseline. Two reviewers independently assessed study eligibility, completed data extraction and undertook quality assessment. Meta-analyses were performed when a prognostic factor was reported in two or more studies.

RESULTS

Of 10,992 studies identified from electronic database searches, 18 were included, investigating 62 potential prognostic factors. In clinical settings, insufficient data were available for meta-analysis. Some positive associations with pain and/or disability were reported by single studies for older age, baseline pain intensity and baseline functional disability across multiple combinations of follow-up times and outcomes. In community settings, meta-analyses of two studies found that prognostic factors for the ongoing presence of pain at medium-term (1-year) follow-up were older age (OR 1.25; 95% CI = 1.05-1.47), weekly day tiredness (OR 1.69; 95% CI = 1.14-2.51), weekly abdominal pain (OR 1.44; 95% CI = 1.03-2.02) and waking during the night (OR 1.49; 95% CI = 1.05-2.13). No studies in community settings reported on prognostic factors for functional disability.

CONCLUSIONS

Prognostic factors having significant associations with future pain and disability were identified; however, as few were investigated in more than one comparable study, the results need to be interpreted with caution.

SIGNIFICANCE

Prognostic factors from across the biopsychosocial spectrum are important to consider in paediatric pain clinical practice. However, most prognostic factors that experts have previously agreed upon have not been assessed in prospective cohort studies to date. The findings may help with prioritising data to collect during clinical assessments of children presenting with pain, in the context of pain and functional disability outcomes.

Talking to Teens about Pain: A Modified Delphi Study of Adolescent Pain Science Education

Background: Persistent pain is a prevalent condition that negatively influences physical, emotional, social and family functioning in adolescents. Pain science education is a promising therapy for adults, yet to be thoroughly investigated for persistent pain in adolescents. There is a need to develop suitable curricula for adolescent pain science education.

Methods: An interdisciplinary meeting of 12 clinicians and researchers was held during March 2018 in Adelaide, South Australia. An a priori objective of the meeting was to identify and gain consensus on key learning objectives for adolescent pain science education using a modified-Delphi process.

Results and Conclusion: Consensus was reached via a modified Delphi process for seven learning objectives to form the foundation of a curriculum: 1) Pain is a protector; 2) The pain system can become overprotective; 3) Pain is a brain output; 4) Pain is not an accurate marker of tissue state; 5) There are many potential contributors to anyone’s pain; 6) We are all bioplastic and; 7) Pain education is treatment. Recommendations are made for promising areas for future research in adolescent pain science education.

Exploring the concept of pain of Australian children with and without pain: qualitative study

OBJECTIVE

A person's concept of pain can be defined as how they understand what pain actually is, what function it serves and what biological processes are thought to underpin it. This study aimed to explore the concept of pain in children with and without persistent pain.

DESIGN

In-depth, face-to-face interviews with drawing tasks were conducted with 16 children (aged 8-12 years) in New South Wales, Australia. Thematic analysis was used to analyse and synthesise the data.

SETTING

Children with persistent pain were identified from a pain clinic waiting list in Australia, and children without pain were identified through advertising flyers and email bulletins at a university and hospital.

PARTICIPANTS

Eight children had persistent pain and eight children were pain free.

RESULTS

Four themes emerged from the data: 'my pain-related knowledge', 'pain in the world around me', 'pain in me' and 'communicating my concept of pain'. A conceptual framework of the potential interactions between the themes resulting from the analysis is proposed. The concept of pain of Australian children aged 8-12 years varied depending on their knowledge, experiences and literacy levels. For example, when undertaking a drawing task, children with persistent pain tended to draw emotional elements to describe pain, whereas children who were pain free did not.

CONCLUSIONS

Gaining an in-depth understanding of a child's previous pain-related experiences and knowledge is important to facilitate clear and meaningful pain science education. The use of age-appropriate language, in combination with appropriate assessment and education tasks such as drawing and discussing vignettes, allowed children to communicate their individual concept of pain.

Best-Evidence for the Rehabilitation of Chronic Pain Part 1: Pediatric Pain

Chronic pain is a prevalent and persistent problem in middle childhood and adolescence. The biopsychosocial model of pain, which accounts for the complex interplay of the biological, psychological, social, and environmental factors that contribute to and maintain pain symptoms and related disability has guided our understanding and treatment of pediatric pain. Consequently, many interventions for chronic pain are within the realm of rehabilitation, based on the premise that behavior has a broad and central role in pain management. These treatments are typically delivered by one or more providers in medicine, nursing, psychology, physical therapy, and/or occupational therapy. Current data suggest that multidisciplinary treatment is important, with intensive interdisciplinary pain rehabilitation (IIPT) being effective at reducing disability for patients with high levels of functional disability. The following review describes the current state of the art of rehabilitation approaches to treat persistent pain in children and adolescents. Several emerging areas of interventions are also highlighted to guide future research and clinical practice.

Pain neuroscience education on YouTube

OBJECTIVES

The Internet in general, and YouTube in particular, is now one of the most popular sources of health-related information. Pain neuroscience education has become a primary tool for managing persistent pain, based in part on the discovery that information about pain can change pain. Our objective was to examine the availability, characteristics, and content of YouTube videos that address the neuroscience of pain.

METHODS

We conducted a systematic review of videos on YouTube using the search terms "pain education", "what is pain", and "pain brain" in January 2018. Videos were included if they were in English, were under 10 minutes long, and included information on the neuroscience of pain. Videos were coded for (i) descriptive characteristics (e.g., number of views, duration on YouTube), (ii) source and style, (iii) whether or not they addressed seven pre-determined target concepts of pain neuroscience education (e.g., 'Pain is not an accurate marker of tissue state'), and (iv) how engaging they were.

RESULTS

We found 106 unique videos that met the inclusion criteria. The videos ranged from having four views to over five million views (Mdn = 1,163 views), with the three most highly viewed videos accounting for 75% of the total views. Animated videos were much more highly viewed than non-animated videos. Only a small number of videos had been posted by a clearly-identifiable reputable source such as an academic or medical institution (10%), although a number of videos were posted by healthcare professionals and professional medical societies. For a small number of videos (7%), the source was unclear. We found 17 videos that addressed at least one target concept of pain neuroscience science education, only nine of which were considered to be at least somewhat engaging. The target concept 'Pain is a brain output' was considered to be well addressed by the most videos (N = 11), followed by 'Pain is a protector' (N = 10). We found only one video that adequately addressed all seven target concepts of pain neuroscience education.

DISCUSSION

YouTube contains a variety of videos that practitioners, patients, and families may view to access pain neuroscience education information. A small portion of these videos addressed one or more target concepts of pain neuroscience education in an engaging manner. It is yet to be determined to what extent patients are able to learn information from these videos, to what extent the videos promote behavior change, and thus to what extent the videos may be useful for clinical practice.

A Child's Concept of Pain: An International Survey of Pediatric Pain Experts

A child's 'concept of pain' refers to how they understand what pain actually is, what function pain serves, and what biological processes are thought to underpin it. We aimed to determine pediatric pain experts' opinions of: (1) the importance and usefulness of assessing a child's concept of pain in clinical and/or research settings; (2) the usefulness of the content of items within currently published adult-targeted resources for assessing a child's concept of pain; and (3) important domains of a child's concept of pain to assess. Forty-nine pediatric pain experts (response rate = 75.4%) completed an online survey. Descriptive statistics and frequency of responses were analyzed. Experts from all included disciplines reported that assessing a child's concept of pain is important and useful both clinically and in a research setting (>80% reported very or extremely useful for each item). Experts considered that the content of 13 items from currently published adult-targeted resources was useful, but the wording was too complex for children aged 8-12 years. Experts considered that all seven of the proposed domains of a child's concept of pain was important to assess. The findings can be used to inform the development of an assessment tool for a child's concept of pain.

Minimal aortic injury: a lesion associated with advancing diagnostic techniques

BACKGROUND

With the increasing use of high-resolution diagnostic techniques, minimal aortic injuries (MAI) are being recognized more frequently. Recently, we have used nonoperative therapy as definitive treatment for patients with MAI. The current study examines our institutional experience with these patients from July 1994 to June 2000.

METHODS

All patients suspected of blunt aortic injury (BAI) by screening helical CT (HCT) underwent confirmatory aortography with or without intravascular ultrasound (IVUS). MAI was defined as a small (<1 cm) intimal flap with minimal to no periaortic hematoma.

RESULTS

Of the 15,000 patients evaluated by screening HCT, 198 (1.3%) were suspected of having BAI. BAI was confirmed in 87 (44%), and 9 (10%) of these had MAI. The initial aortogram was considered normal in five of the MAI patients. The correct diagnosis was made by IVUS (four patients), and video angiography (one patient). One MAI patient had surgery, and two (22%) died of causes not related to the aortic injury. Follow-up studies were done on the six MAI patients that were discharged. In two, the flap had completely resolved, and in one it remained stable. The remaining three patients formed small pseudoaneurysms.

CONCLUSION

Ten percent of BAI diagnosed with high resolution techniques have MAI. These intimal injuries heal spontaneously and hence may be managed nonoperatively. However, the long-term natural history of these injuries is not known, and hence caution should be exercised in using this form of treatment.

Traumatic rupture of the aortic isthmus: program of selective management

Two hypotheses were investigated: (1) helical computed tomography (CT) of the chest on victims of decelerating trauma can yield a diagnosis of, or "rule out," a traumatic rupture of the aorta (TRA) without the need for an aortogram; and (2) selective delay of aortic repair can be safely accomplished through a medical management protocol. Screening helical CT examinations were done on 6169 victims of blunt thoracic trauma; 47 were found to have TRA; in 8, indirect but nondiagnostic findings not clarified by an aortogram led to surgical exploration. The sensitivity of helical CT was higher than that of aortograms, and a "normal" helical CT scan was never associated with a proved TRA. It is estimated that the use of helical CT has resulted in at least a 40% to 50% decrease in the need for aortograms, in addition to yielding rapid, noninvasive valuable information about other injuries. Drugs (beta-blockers +/- vasodilators) to decrease the stress in the aortic wall were used in 93 patients when the diagnosis was suspected and were continued as necessary through the evaluation, stabilization, and until the aorta was cross-clamped at operation. Elective, delayed operation was done between 2 days and 25 months in 15 patients who were deemed to be excessive risks for emergency aortic repair; there were 2 deaths (13. 3%). Eleven patients never had aortic repair. No patient maintained on this protocol, whether repaired emergently, electively, or not at all, developed free rupture of the periaortic hematoma and death from TRA.

Prospective study of blunt aortic injury: helical CT is diagnostic and antihypertensive therapy reduces rupture

OBJECTIVE

There were two aims of this study. The first was to evaluate the application of helical computed tomography of the thorax (HCTT) for the diagnosis of blunt aortic injury (BAI). The second was to evaluate the efficacy of beta-blockers with or without nitroprusside in preventing aortic rupture.

SUMMARY BACKGROUND DATA

Aortography has been the standard for diagnosing BAI for the past 4 decades. Conventional chest CT has not proven to be of significant value. Helical CT scanning is faster and has higher resolution than conventional CT. Retrospective studies have suggested the efficacy of antihypertensives in preventing aortic rupture.

METHODS

A prospective study comparing HCTT to aortography in the diagnosis of BAI was performed. A protocol of beta-blockers with or without nitroprusside was also examined for efficacy in preventing rupture before aortic repair and in allowing delayed repair in patients with significant associated injuries.

RESULTS

Over a period of 4 years, 494 patients were studied. BAI was diagnosed in 71 patients. Sensitivity was 100% for HCTT versus 92% for aortography. Specificity was 83% for HCTT versus 99% for aortography. Accuracy was 86% for HCTT versus 97% for aortography. Positive predictive value was 50% for HCTT versus 97% for aortography. Negative predictive value was 100% for HCTT versus 97% for aortography. No patient had spontaneous rupture in this study.

CONCLUSIONS

HCTT is sensitive for diagnosing intimal injuries and pseudoaneurysms. Patients without direct HCTT evidence of BAI require no further evaluation. Aortography can be reserved for indeterminate HCTT scans. Early diagnosis with HCTT and presumptive treatment with the antihypertensive regimen eliminated in-hospital aortic rupture.

Blunt injuries of the brachiocephalic artery

Blunt injury of the brachiocephalic artery can pose diagnostic and management problems for the trauma and thoracic surgeon. To arrive at recommendations for dealing with this injury, we reviewed a seven-year experience at our trauma center. Between 1988 and 1995, five patients presented with blunt injuries of the brachiocephalic artery. All patients were stabilized and underwent repair through a median sternotomy with extension of the incision anterior to the sternocleidomastoid muscle. All patients had restoration of flow to the subclavian and carotid arteries utilizing bypass grafts (4) or primary repair (1). All patients survived to leave the hospital with no complications related to the procedure. Postoperative neurologic findings were present before the operative repair. Patients with blunt injuries of the brachiocephalic artery should be stabilized, and circulation of the subclavian and carotid arteries should be restored with graft placement or primary repair. Cardiopulmonary bypass and heparin or temporary shunts were not needed in this series of patients. Complications were related to associated injuries.

Perfluorocarbons: future clinical possibilities

Perfluorocarbons are now being used as oxygen carriers in clinical settings. Because these chemicals may have a role as a blood substitute, in organ preservation, and in the management of respiratory failure, we have reviewed some of the research leading to these applications.

Subclavian artery injuries

Thirty-two consecutive patients with subclavian artery injuries were evaluated to assess the mechanism of injury, types of repair, and results. In this series, most wounds were from firearms. Although the mortality was high (19%), most patients had the vessel repaired successfully. Associated injuries, especially to neural structures, led to significant morbidity. Principles used in dealing with these injuries should be 1) proximal and distal control prior to exposing the injury site, 2) reestablishing distal circulation through primary repair or graft placement, and 3) identifying and treating associated injuries.

Function of "nontrauma" surgeons in level I trauma centers in the United States

Although the general "trauma" surgeon is usually the team leader in level I trauma centers, the use of surgical subspecialists and nonsurgeons is frequently ill-defined. This study was done to gain data in regard to actual use of subspecialists in busy centers. First, a survey of the patterns of staffing in 140 trauma centers was elicited by mail questionnaire, supplemented by telephone cells. Second, records of 400 consecutive patients at the Elvis Presley Trauma Center were reviewed to determine the use of subspecialists during the first 24 hours of care of individual patients. There were differences in the use of surgical subspecialists and nonsurgeons at different centers: in receiving, admitting, operating, and critical care areas and in privileges for admission and attending of inpatients. Consultation "guidelines" are used for many specific injuries. At our center, a mean of 1.92 subspecialists, in addition to general surgeons, were involved in the early care of each patient. Problems exist in many centers regarding the use of subspecialists, especially for management of facial and chest injuries. In some centers nonsurgeons function in the intensive care unit, and as admitting and attending physicians of trauma patients.

Combined gunshot injuries of the trachea and esophagus

During an 8-year period between 1985 and 1993, twelve patients were treated with combined gunshot wounds to the trachea and esophagus. All patients survived, but there were complications, including one tracheoesophageal fistula. Combined injuries of the trachea and esophagus should be repaired primarily, and drains do not necessarily have to be placed. The benefit of a muscle flap placed between the repairs was not confirmed in this series. Complications should be recognized early and treated aggressively to minimize damage to the airway.

Is routine carotid screening for coronary surgery needed?

An association between carotid and coronary artery disease is well recognized. Routine preoperative duplex carotid screening of all coronary surgery patients is common, but may delay surgery and increase cost. To evaluate such a policy: A retrospective review of the records of 308 consecutive patients undergoing coronary surgery at one hospital was performed. Duplex studies were done on 210. A history of TIA/RIND, CVA, AS-PVD, AAA, neck bruit, or prior carotid surgery was considered suggestive for carotid disease. The history and/or physical exam (HPE) suggested carotid disease in 114; 37 of these (32%) had a positive scan. Of 96 patients without +HPE, three (3%) had a significant stenosis. A prospective study of cardiac surgery patients was done, categorized into "carotid" (n = 33) or "no-carotid" (n = 50) disease by two independent observers, based on +HPE. Positive scans were found in 27 per cent of the "carotid disease" group; No positive scans were found in the "no-carotid disease" group. We conclude that coronary surgery patients with peripheral or cerebral vascular disease or a neck bruit should have preoperative carotid studies. Duplex carotid screening of all cardiac patients is neither medically efficient nor cost-effective.

Coronary operations in patients with spinal cord injury

BACKGROUND

The risk of heart disease in patients with spinal cord injury is similar to that in the general population. The physiologic derangements raise special problems in patients with SCI having coronary operations.

METHODS

From January 1980 to May 1995, we performed coronary artery bypass procedures on 20 patients with SCI; 4 were tetraplegic and the remainder were paraplegic. The indication for operation was angina: unstable (13), exertional (4), or postinfarctional (3). Bowel and bladder care was given immediately before operation; operating room tables were double padded and a pelvic wrap was used to protect the back. Electric wheelchairs were used for early mobilization.

RESULTS

Vasomotor instability from cardiopulmonary bypass was not present in patients with SCI. Pharmacologic support was required in the operating room by 4 patients for low vascular resistance, but in only one case in the intensive care unit. One patient required ventilation support for more than 24 hours. All patients were able to cough effectively. No thoracic wound complications occurred. There were three operative deaths, all in patients with multiple risk factors. The acute hospital stay averaged 9.3 days; patients were then transferred to an SCI unit for rehabilitation, were upper-extremity weight bearing was restricted for 2 to 4 weeks.

CONCLUSIONS

Patients should not be denied coronary artery bypass procedures because of an SCI, but their special needs must be managed properly.

Combined tracheal and esophageal trauma from gunshot wounds

During a 5-year period between 1988 and 1993, nine patients with combined tracheal and esophageal injuries were treated at our institution. All injuries resulted from gunshot wounds and all were repaired. All patients survived, but complications included one tracheoesophageal fistula. Combined injuries of the trachea and esophagus should be repaired primarily, and drains do not necessarily have to be placed. The benefits of a muscle flap placed between the repairs were not confirmed in this series. Complications should be recognized early and treated aggressively to minimize damage to the airway.

Video-assisted thoracic surgery: primary therapy for spontaneous pneumothorax?

OBJECTIVE:

To determine whether video-assisted thoracoscopic surgery is as effective as the traditional open method through axillary thoracotomy for the management of primary spontaneous pneumothorax in adults.

MATERIALS AND METHODS:

This retrospective study was conducted at King Hussein Medical Center in the period between March 2002 and March 2007. Eighty-two patients were included in this study. The patients were divided in two groups: group A, which included patients who underwent video-assisted thoracoscopic surgery; and group B, which included patients who underwent open technique through axillary thoracotomy. Efficiency of the procedure, operative time, postoperative complications, length of hospital stay, time to return to work and recurrence were compared between the two groups.

RESULTS:

There were 79 males (96.3%) and 3 females (3.7%) with a mean age of 23.7 ± 4.2 years for group A patients and 24.2 ± 4.6 years for group B patients (range 16–37 years). Forty-one patients (50%) underwent video-assisted thoracoscopic surgery (group A), and 41 patients (50%) underwent open surgical technique through axillary thoracotomy (group B). Postoperative complication occurred in 8 patients (19.3%) from among those who underwent open technique and 6 patients (14.6%) from among those who underwent thoracoscopic technique. There was no perioperative mortality in both groups. Postoperative pain, volume of blood loss, period of air leak and hospital stay were less in group A, although the operative time was less in group B.

CONCLUSION:

Video-assisted thoracoscopic surgery is an efficient and safe method for the treatment of patients with primary pneumothorax in the adults.

Chest wall resection for Ewing's sarcoma of the rib: an unnecessary procedure. 1988. Updated in 1995

Approximately 10% of all cases of Ewing's sarcoma arise from a rib. Conventional management has included chest wall resection (3 or more ribs) and radiation therapy. These forms of therapy have led to complications such as scoliosis and local deformity. The addition of radiation therapy can result in damage to the lung and adjacent viscera and also potentiate pulmonary restrictive disease. Between 1971 and 1978, 9 patients were treated with surgery, radiation therapy, and combination chemotherapy (three- or four-drug regimen). Only 2 patients (22%) survive. Since 1979, 14 patients were entered into a new protocol consisting of sequential induction chemotherapy, followed by delayed surgical resection whenever feasible. Three patients had complete resection of their primary lesion at onset. Initially, 7 patients had either biopsy (N = 4) or incomplete chest wall resection N = 3). All 4 patients with biopsy only at diagnosis had excellent responses to induction chemotherapy, allowing delayed resection of the involved rib without chest wall resection. Overall, 12 of 14 patients (86%) treated since 1979 survive, with only 2 receiving radiation therapy for residual disease in the primary rib site.

Video-assisted thoracic surgery: primary therapy for spontaneous pneumothorax?

BACKGROUND

This study assessed the role of video-assisted thoracic surgery (VATS) in current therapy for spontaneous pneumothorax.

METHODS

We compared a retrospective series of 89 patients treated conventionally with a consecutive group of 30 patients undergoing VATS pleural abrasion. The 89 earlier patients were predominantly male (81%). Treatment groups included observation/aspiration (7 or 17%), tube thoracostomy (32 or 36%), multiple tubes (7 or 9%), and thoracotomy (43 or 48%). Of the 30 patients treated with VATS, 18 (66%) were male. Primary indications for operation were recurrent pneumothorax (17) and persistent air leak (9).

RESULTS

Hospital lengths of stay (LOS) for the earlier group were 5 days for simple tube and 7 days for primary thoracotomy; LOS for initial intervention followed by thoractomy exceeded 15 days in all subgroups. The average LOS in the VATS group was 13 days; 6 patients treated with primary VATS (no chest tube) had a mean LOS of 6.5 days. Complications included 3 (10%) prolonged air leaks (more than 7 days) and 2 (7%) early recurrences.

CONCLUSIONS

We do not recommend VATS as primary therapy for spontaneous pneumothorax; tube thoracostomy remains the treatment of choice. However, we strongly support surgical intervention early (3 days) in patients with a persistent air leak, and as primary therapy in a nonurgent situation if standard indications exist. This study shows no advantage of VATS over conventional thoracotomy in hospital stay or complication rate.

Noniatrogenic esophageal trauma

Few guidelines are available with which to facilitate treatment in patients with noniatrogenic injuries of the esophagus. Early diagnosis and proper management are essential if a good outcome is to be expected. In an effort to define better the treatment of patients with penetrating and blunt injuries of the esophagus, we report our recent 5-year experience at an urban trauma center. From July 1988 to June 1993, nineteen patients with esophageal perforations from penetrating (18) and blunt (1) trauma were identified by our trauma registry. There was no mortality in this group of patients and morbidity was mostly due to associated injuries. Eleven cervical esophageal injuries were repaired. One cervical injury was treated by stopping oral intake and giving intravenous antibiotics. The neck was not drained in 10 of the surgical cases. In 1 patient a tracheoesophageal fistula developed, which later was repaired with a pectoralis muscle flap. Seven perforations were identified in the thoracic (2) and abdominal (5) portions of the esophagus. All were due to gunshot wounds. In 4 cases, a fundal wrap was used to reinforce the repairs. Postoperative contrast studies confirmed that all repairs were intact. We conclude that penetrating and blunt tears of the esophagus can be repaired safely with minimal mortality. Morbidity is usually from associated injuries such as to the spinal cord and trachea. When identified early, cervical esophageal injuries do not need to be drained routinely.

Acute traumatic rupture of the aortic isthmus: repair with cardiopulmonary bypass

In an attempt to prevent paraplegia, a devastating complication common after the repair of traumatic rupture of the aorta, we have used partial cardiopulmonary bypass. Most of the patients in our series (79.5%) underwent other major surgical procedures immediately before or after the aortic repair. Eight of the 110 patients died before aortic repair could be performed. The aorta was not repaired in 3, because of other injuries. In 9, the repair was done without a shunt or bypass; 4 patients died and 2 (22.2%) survived without paraplegia. One of the 2 who underwent repair with a Gott shunt died; the survivor suffered no cord damage. Of the 88 patients whose repair was carried out under cardiopulmonary bypass, 6 died and 80 (90.9%) survived without paraplegia. None of the last 39 patients has become paraplegic, as vasodilator treatment is now discontinued during the cross-clamp period. Serious intracranial injury was present in 19 patients; in 3 (15.8%) the injury became worse after repair. There was no evidence of new or increased intraabdominal bleeding during heparinization. Except in the event of pulmonary lacerations, systemic heparin therapy was not associated with major problems.

Traumatic rupture of the aortic isthmus: an emergency?

The objectives of this study were to explore the hypotheses that: (1) patients with traumatic rupture of the aortic isthmus (TRA) who have not exsanguinated into the pleural cavity upon hospital presentation are unlikely to develop rupture of the hematoma during the time necessary to investigate all injuries and attend to those of more immediate danger; and (2) appropriate medical therapy can prevent free rupture of the hematoma. The medical records of 112 patients who were proved to have TRA at the isthmus resulting from injury within the preceding 7 days were reviewed. Fifty of these patients received medical treatment aimed at decreasing aortic wall stress; 46 were managed under a formal protocol. The available English language and European literature for the past 15 years was surveyed for evidence of the effects of delay between injury and aortic repair. Eight patients died before aortic repair, six of aortic exsanguination (all within 4 hours of injury). Of 77 patients for whom the time of injury was recorded and the aorta was repaired, 36 were repaired within 12 hours of injury and 41 between 12 hours and 24 weeks; none developed aortic hemorrhage. No patient receiving adequate medical therapy died of rupture of the hematoma. Other major surgery preceded aortic repair in 33 patients. We conclude that the concept that traumatic rupture of the aorta should always take priority over other injuries is incorrect. Pharmacologic reduction of wall stress appears to decrease the probability of rupture of the periaortic hematoma.

Intraluminal shunt for the thoracic aorta: spinal cord and visceral blood flow in acute studies

Aortic cross-clamping during surgery of the thoracic aorta may result in paraplegia or kidney failure. Difficulties associated with external shunts and bypasses have limited their use. Therefore we compared intraluminal shunting to the nonshunting method of repair in neonatal pigs. Blood flow to the spinal cord and viscera was measured with radiolabeled microspheres before, during, and after thoracic aortic cross-clamping or shunting. Two no-shunt groups were studied: One group was clamped distal to the left subclavian artery for 30 minutes and the other for 1 hour. In the intraluminal shunt group, a shunt was placed in the aorta just below the ligamentum arteriosum for 1 hour; it was then removed and the aorta repaired. In the no-shunt groups, there was virtually no blood flow to the lower cord and viscera during the cross-clamp period. Hyperemia of the lower thoracic and lumbar cord occurred in the no-shunt 30-minute group 15 minutes after clamp removal. In the no-shunt 60-minute group, flow initially returned to the lumbar cord but then declined; and after 1 hour of reperfusion it was significantly lower than baseline. Renal blood flow was even more severely affected in the no-shunt 60-minute group, with minimal recovery during the reperfusion period. In the intraluminal shunt group baseline spinal cord and visceral blood flow were maintained during thoracic aortic cross-clamping, without the problems associated with extracorporeal circulation.

In defense of malpractice charges: a survey of the legal process

Surgeons need to be more informed and cognizant of the ramifications of the legal process to participate properly in their defense or to serve as expert witnesses. The education, training, experience, and psychology of surgeons provide a different background from that needed in a legal contest. As the saying goes, "The battle begins when the suit is served." Attention to detail and defensive, conservative, and humble attitudes should begin then. Although cases are not won in the early stages or during the discovery process, they may well be lost there. The surgeon's improper attitude and lack of preparation may be responsible for many of these losses. The process is expensive and time-consuming, but attempts to avoid this time commitment during the pretrial stages are ill advised. With understanding, close cooperation with counsel, and proper preparation, the surgeon will be a potent force in his or her own defense.
