Guidelines for chronic noncancer pain prioritize behavioral treatments. In clinical practice transition from opioids to behavioral treatments is often not endorsed by patients or providers. Feasible interventions to support opioid tapering are needed, particularly in primary care. The objectives of this paper is to review the feasibility of behavioral interventions to support opioid tapering. Electronic databases (MEDLINE, Embase, PsycINFO, and CINAHL) were searched from inception to June 2019 to identify original studies reporting feasibility (consent rates; completion rates; patient-reported acceptability; integration into clinical practice; and adverse events) of opioid tapering and transition to behavioral treatments for adults experiencing chronic noncancer pain. Google scholar and contents tables of key journals were also searched. Two authors independently extracted data and assessed methodological quality using The Quality Assessment Tool for Quantitative Studies. Eleven publications met inclusion criteria, of which three were conducted in primary care. Consent rates ranged from 27% to 98% and completion rates from 6.6% to 100%. Four studies rated at least one component of patient acceptability: helpfulness from 50%–81%; satisfaction 71%–94%, and “recommend to others” 74%–91%. Three studies reported provider perspectives and two studies reported adverse events. Quality assessment indicated all 11 studies were moderate or weak, primarily due to selection bias and lack of assessor blinding. There was also considerable heterogeneity in study design. The limited available data suggest that attempts to translate opioid tapering interventions into practice are likely to encounter substantial feasibility challenges. One possible way to ameliorate this challenge may be a clear policy context, which facilitates and support opioid reduction.

Objectives This study examined the effects of sacubitril/valsartan on N-terminal pro–B-type natriuretic peptide (NT-proBNP) levels and determined patient characteristics associated with favorable NT-proBNP reduction response. Background NT-proBNP levels reflect cardiac wall stress and predict event risk in patients with acute decompensated heart failure (ADHF). Methods Post-hoc analysis of the TRANSITION (Comparison of Pre- and Post-discharge Initiation of Sacubitril/Valsartan Therapy in HFrEF Patients After an Acute Decompensation Event) study, including stabilized ADHF patients with reduced ejection fraction, randomized to open-label sacubitril/valsartan initiation in-hospital (pre-discharge) versus post-discharge. NT-proBNP was measured at randomization (baseline), discharge, and 4 and 10 weeks post-randomization. A favorable NT-proBNP response was defined as reduction to ≤1,000 pg/ml or >30% from baseline. Results In patients receiving sacubitril/valsartan in-hospital, NT-proBNP was reduced by 28% at discharge, with 46% of patients obtaining favorable NT-proBNP reduction response compared with a 4% reduction and 18% favorable response rate in patients initiated post-discharge (p Conclusions In-hospital initiation of sacubitril/valsartan produced rapid reductions in NT-proBNP, statistically significant at discharge. A favorable NT-proBNP response over time was associated with a better prognosis and predicted by higher starting dose and predisposing clinical profile.

Chronic pain, once termed a hidden epidemic, is gaining increasing visibility around the world. It places a huge burden on patients, their families, and the wider community, with profound adverse effects on function, well-being, and quality of life. It is also a socioeconomic problem, straining health-care systems globally. This article provides an overview of the changing landscape of chronic noncancer pain. The epidemiology, classification, pain-related neuroscience, problems with overemphasis on biomedical focus, and the importance of adopting a more holistic sociopsychobiomedical framework are discussed. The article concludes with a brief discussion on health-care delivery systems in the context of chronic pain.

Introduction: Integrated team-based primary healthcare is well positioned to support opioid tapering for patients experiencing chronic pain. This paper describes the development, implementation and acceptability of a primary healthcare opioid tapering intervention ‘Assess Inform Manage Monitor’ (AIMM) at two sites. Methods: AIMM involved GP advice; nurse monitoring and potential engagement with: community pharmacist; psychologist; dietitian and exercise physiologist. Individuals receiving 90 days or more of prescription opioids were eligible. Patient and provider surveys and qualitative interviews were completed. Results: Of 140 eligible patients, 37 attended during the study period and were invited to participate. Patient post-intervention surveys (n = 8) and interviews (n = 6) indicated the intervention was acceptable, although the perceived value of some of the integrated team was low. GP and practice nurse support was valued. Providers (n = 4) valued team integration. Low weaning readiness was a barrier to engagement by patients and providers. Key lessons and conclusions: The intervention, whilst conceptually acceptable, was not feasible in its current form. Future efforts to transition patients towards integrated care should retain the practice nurse and place more focus on understanding and reinforcing patients’ readiness to wean. Greater inter-professional collaboration may also be needed. Such refinements may advance the cause of opioid reduction in primary care.

Purpose Active pain self-management (PSM) for patients with chronic pain is assumed to require multidisciplinary care, leaving prescribing analgesics the most accessible option for general practitioners (GPs). We sought to upskill GPs in multimodalPSM with a harm minimisation approach for any opioid prescribing. Design and Methodology Having developed an educational training resource, a multidisciplinary team delivered the program to attendees at a GP conference in 2017. The educational package comprised pre-readings, a 6-hour interactive, skills-based workshop, and post-workshop resources. The single-group intervention was evaluated with an original and unvalidated pre/post-test (three months) survey of four domains: knowledge; attitudes; utilisation of strategies involving PSM and opioid harm minimization. Paired t-tests were conducted on each domain score and overall, with effect sizes assessed with Cohen’s d. A sensitivity analysis was performed on the data lacking a post-test survey response. Post-survey scores were imputed via chained regression equations, then paired t-tests analyses were conducted on imputed datasets using Rubin's method to pool estimates. Findings Of 99 participants, 33 returned both surveys for primary analysis. These were combined in the sensitivity analysis with 60 unpaired surveys. Internal consistency was modest (Cronbach’s alpha 0.736). Primary analysis demonstrated significant self-reported improvements in each educational domain with overall score increasing 10.54 points out of 130 (p

Background General practitioners' (GPs) views about deprescribing prescription opioid analgesics (POAs) may influence the care provided for patients experiencing chronic noncancer pain (CNCP). There are limited data addressing GPs' beliefs about deprescribing, including their decisions to deprescribe different types of POAs. Aim To determine the proportion of GPs who hold attitudes congruent with local pain stewardship, describe their deprescribing decisions, and determine whether type of POA influences deprescribing. Design and setting In 2016, a cross-sectional survey of all GPs (n=1,570) in one mixed urban and regional primary health network (PHN) in Australia was undertaken. Methods A mailed self-report questionnaire assessed agreement with local guidelines for treating CNCP; influences on deprescribing POAs and likelihood of deprescribing in a hypothetical case involving either oral codeine or oxycodone. Results A response rate of 46% was achieved. Approximately half (54%) of GPs agreed POAs should be reserved for people with acute, cancer pain or palliative care and a third (32%) did not agree that a medication focus has limited benefits for peoples' long-term quality of life and function. Most (77%) GPs were less likely to deprescribe when effective alternate treatments were lacking, while various patient factors (eg, fear of weaning) were reported to decrease the likelihood of deprescribing for 25% of GPs. A significantly higher proportion of GPs reported being very likely to deprescribe codeine compared to the equivalent opioid dose of oxycodone for a hypothetical patient. Conclusions Many GPs in the PHN hold attitudes at odds with local guidance that opioids are a nonsuperior treatment for CNCP. Attitudinal barriers to deprescribing include: a lack of consistent approach to deprescribing opioids as a class of drugs, perceived lack of effective treatment alternatives and patient fear of deprescribing. Therefore, the next step in this target population is to appropriately train and support GPs in how to apply the evidence in practice and how to support patients appropriately.

Opioids have important roles in the time-limited treatment of acute and cancer pain, end-of-life pain or dyspnoea, and in opioid dependency. Maintaining focus on biomedical treatments, including drugs, has limited success in chronic pain. Active self-management and healthy lifestyle choices are fundamental to addressing multisystem complexity and harnessing neuroplasticity in chronic pain. Addressing psychosocial maladaptations and physical deconditioning requires a variety of approaches, frequently involving multiple care providers. In practice, most pain care is delivered outside specialist centres by GPs and other non-pain specialists. Although they are well placed to provide multimodal care, they often lack training and confidence in delivering this care.

Background Despite their potential interest for clinical management, measurements of respiratory mechanics in patients with acute respiratory distress syndrome (ARDS) are seldom performed in routine practice. We introduced a systematic assessment of respiratory mechanics in our clinical practice. After the first year of clinical use, we retrospectively assessed whether these measurements had any influence on clinical management and physiological parameters associated with clinical outcomes by comparing their value before and after performing the test. Methods The respiratory mechanics assessment constituted a set of bedside measurements to determine passive lung and chest wall mechanics, response to positive end-expiratory pressure, and alveolar derecruitment. It was obtained early after ARDS diagnosis. The results were provided to the clinical team to be used at their own discretion. We compared ventilator settings and physiological variables before and after the test. The physiological endpoints were oxygenation index, dead space, and plateau and driving pressures. Results Sixty-one consecutive patients with ARDS were enrolled. Esophageal pressure was measured in 53 patients (86.9%). In 41 patients (67.2%), ventilator settings were changed after the measurements, often by reducing positive end-expiratory pressure or by switching pressure-targeted mode to volume-targeted mode. Following changes, the oxygenation index, airway plateau, and driving pressures were significantly improved, whereas the dead-space fraction remained unchanged. The oxygenation index continued to improve in the next 48 h. Conclusions Implementing a systematic respiratory mechanics test leads to frequent individual adaptations of ventilator settings and allows improvement in oxygenation indexes and reduction of the risk of overdistention at the same time. Trial registration The present study involves data from our ongoing registry for respiratory mechanics (ClinicalTrials.gov identifier: NCT02623192. Registered 30 July 2015).

Background Chronic non-cancer pain (CNCP) frequently co-occurs with other chronic conditions, resulting in multimorbidity. Objective The aim of this article is to summarise current approaches to CNCP management and explore areas of specificity and overlap with chronic conditions in general. Discussion The biomedical component of the management of chronic conditions may be condition-specific. However, mind-body, connection, activity and nutrition components entail significant overlap and are helpful across conditions. Effective practice avoids overemphasis on medical treatments at the expense of evidence-based, multidimensional lifestyle approaches. CNCP management illustrates the case for reconceptualising chronic condition management using a generic lifestyle-based approach. This capitalises on overlapping treatments, creates system efficiency and allows patients with multimorbidity to be treated more effectively in primary care, with only a small subgroup referred to condition-specific tertiary services.

Background. Local chronic non-cancer pain guidance recommends that general practitioners should consider opioid deprescribing and referral to multidisciplinary healthcare providers for behaviourally based treatments . We designed a training package called AIMM (Assess, Inform, Manage and Monitor) to reinforce this stewardship. Aim. To identify whether participation in AIMM training effectively aligned clinicians’ attitudes with local guidance for treating chronic non-cancer pain . Design and setting. In 2014–15, the AIMM training was tested using a pre–post-test non-randomised design at two sites in NSW, Australia. The primary outcome measure was an 11-item, study-specific, pain attitude questionnaire (PAQ). Method. Step one of AIMM training involved online completion of the PAQ and review of a specialist pain website. Step two involved attendance at two face-to-face, two-hour interactive workshops led by pain experts who addressed opioid deprescribing and switching to broader care. A repeat PAQ survey was completed at the conclusion of the second workshop. Results. Nineteen participants attended the workshops, including general practitioners (n = 7), nurses (n = 5), exercise physiologists (n = 2), a dietitian (n = 1), community pharmacists (n = 2) and psychologists (n = 2). Significant shifts in six attitudes occurred, including prescribing less pain medication, greater emphasis on social reconnection, increasing planned activity and adopting anti-inflammatory nutrition (p

There is a substantial clinical variation in the contemporary treatment of chronic noncancer pain reflecting different explanatory models and treatment emphasis. Hunter Integrated Pain Service and collaborators developed three key messaging videos outlining the foundations of chronic pain treatment, thus challenging unwarranted clinical variation and calling for greater therapeutic consistency. The videos were released on YouTube as a low-cost public health intervention. Each video used an evidenced informed script appropriate for low literacy and a cartoonist to provide matching images. The whole-person approach emphasized the role of the nervous system and active self-management approaches over passively received medical treatments. The first video was launched on YouTube in August 2011 and made freely available through a Creative Commons license. Multisource feedback led to refinement of key messages using a broader advisory group. Two further videos were launched on a dedicated YouTube channel in October 2014 and circulated through varied professional and consumer networks. All videos were widely viewed on YouTube, utilized by diverse health care organizations, and independently translated into multiple languages. They were embedded in multiple health-related websites. The first video “Understanding pain in less than 5 minutes” is known to have been translated into 15 languages by other health care organizations. The subsequent two videos (Brainman stops his opioids, and Brainman chooses) were translated into German and subtitled in French and Japanese. When the organization hosting the first video ceased operation in 2015 due to changes in primary health care funding, the video had received >700,000 views. Each of the three videos continues to receive ~1,500 views per month on YouTube. Release of evidence-informed key messages via YouTube is a simple method of challenging clinical variation and providing education about chronic pain across the health care system and community., Video abstract

The aim of this study was to examine the effect of a six-week 2 &times, 2 design on pain scores, quality of life, and dietary intake in patients attending an Australian tertiary pain clinic. The two intervention components were (1) personalized dietary consultations or waitlist control, and (2) active or placebo dietary supplement (fruit juice). Sixty participants were randomized into one of four groups at baseline (68% female, mean age 49 &plusmn, 15 years) with 42 completing the study (70% retention). All groups had statistically significant improvements in three of five pain outcomes. The personalized dietary consultation groups had clinically important improvements in three of five pain outcomes compared to the waitlist control groups. All groups had a statistically significant improvement in six of eight quality-of-life categories post intervention. All groups increased percentage energy from nutrient-dense foods (+5.2 &plusmn, 1.4%, p &lt, 0.001) with a significant group-by-time effect for percentage energy from total fat (p = 0.024), with the personalized dietary consultations plus placebo fruit juice reporting the largest reduction (&minus, 5.7 &plusmn, 2.3%). This study indicates that dietitian-delivered dietary intervention can improve pain scores, quality of life, and dietary intake of people experiencing chronic pain. Future research should evaluate efficacy in a full-powered randomized control trial.

Background This systematic review aimed to evaluate the impact of nutrition interventions on participant reported pain severity and intensity in populations with chronic pain. Methods Eight databases were systematically searched for studies that included adult populations with a chronic pain condition, a nutrition intervention and a measure of pain. Where possible, data were pooled using meta-analysis. Seventy-one studies were included, with 23 being eligible for meta-analysis. Results Studies were categorised into four groups: (i) altered overall diet with 12 of 16 studies finding a significant reduction in participant reported pain; (ii) altered specific nutrients with two of five studies reporting a significant reduction in participant reported pain; (iii) supplement-based interventions with 11 of 46 studies showing a significant reduction in pain; and (iv) fasting therapy with one of four studies reporting a significant reduction in pain. The meta-analysis found that, overall, nutrition interventions had a significant effect on pain reduction with studies testing an altered overall diet or just one nutrient having the greatest effect. Conclusions This review highlights the importance and effectiveness of nutrition interventions for people who experience chronic pain.

Introduction Advocacy and commercially funded education successfully reduced barriers to the provision of long-term opioid analgesia. The subsequent escalation of opioid prescribing for chronic noncancer pain has seen increasing harms without improved pain outcomes. Methods This was a one-group pretest-posttest design study. A multidisciplinary team developed a chronic pain educational package for general practitioner trainees emphasizing limitations, risk-mitigation, and deprescribing of opioids with transition to active self-care. This educational intervention incorporated prereadings, a resource kit, and a 90-minute interactional video case-based workshop incorporated into an education day. Evaluation was via pre- and postintervention (two months) questionnaires. Differences in management of two clinical vignettes were tested using McNemar's test. Results Of 58 eligible trainees, 47 (response rate = 81.0%) completed both questionnaires (36 of whom attended the workshop). In a primary analysis including these 47 trainees, therapeutic intentions of tapering opioid maintenance for pain (in a paper-based clinical vignette) increased from 37 (80.4%) pre-intervention to 44 (95.7%) postintervention (P = 0.039). In a sensitivity analysis including only trainees attending the workshop, 80.0% pre-intervention and 97.1% postintervention tapered opioids (P = 0.070). Anticipated initiation of any opioids for a chronic osteoarthritic knee pain clinical vignette reduced from 35 (74.5%) to 24 (51.1%; P = 0.012) in the primary analysis and from 80.0% to 41.7% in the sensitivity analysis (P = 0.001). Conclusions Necessary improvements in pain management and opioid harm avoidance are predicated on primary care education being of demonstrable efficacy. This brief educational intervention improved hypothetical management approaches two months subsequently. Further research measuring objective changes in physician behavior, especially opioid prescribing, is indicated.

We describe the characteristics of patients attending an Australian tertiary multidisciplinary pain service and identify areas for nutrition interventions. This cross-sectional study targets patients experiencing chronic pain who attended the service between June–December 2014. Self-reported data was captured from: (1) an Electronic Persistent Pain Outcomes Collaboration (ePPOC) referral questionnaire, incorporating demographics, pain status, and mental health; (2) a Pain Assessment and Recovery Plan (PARP), which documents patients’ perceived problems associated with pain and personal treatment goals. The ePPOC referral questionnaire was completed by 166 patients and the PARP by 153. The mean (SD) patient age was 53 ± 13 years, with almost 60% experiencing pain for >5 years. Forty-five percent of patients were classified as obese (BMI ≥ 30 kg/m2, mean (SD) BMI was 31 ± 7 kg/m2), with a mean waist circumference of 104 ± 19.4 cm (SD). The most frequent patient nominated treatment goals related to physical activity (39%), followed by nutritional goals (23%). Traditionally, pain management programs have included physical, psychosocial, and medical, but not nutritional, interventions. By contrast, patients identified and reported important nutrition-related treatment goals. There is a need to test nutrition treatment pathways, including an evaluation of dietary intake and nutrition support. This will help to optimize dietary behaviors and establish nutrition as an important component of multidisciplinary chronic pain management.

Purpose Rapid response teams (RRTs) were created to stabilize acutely ill patients on the ward, but recent studies suggest that RRTs may improve end-of-life care (EOLC). To learn more about the role of the RRT in EOLC at our institutions, we conducted a retrospective review. Methods Retrospective review of 300 RRT consultations at 3 academic hospitals in Toronto, Canada. Results The typical consultation was for an elderly patient with chronic illness. More than 90% had a “full resuscitation” order at the time of consultation. One third were admitted to the intensive care unit within 48 hours of the RRT consultation, and 24.7% ultimately died. Twenty-seven (9.3%) had a patient/family conference on the ward within 48h of the RRT consultation, 24 (8.3%) of whom changed their resuscitation order as a result. Among those who changed their resuscitation order, fewer than 20% were referred to the palliative care or spiritual care service, or prescribed comfort medications as needed (pro re nata), within 48h of the RRT consultation; 2 patients died without receiving any common EOLC orders, and 15 (63%) died before discharge. Conclusions RRT consultation is an important milestone for many patients approaching EOL. RRTs frequently participate in EOL discussions and decision-making, but they may miss opportunities to facilitate EOLC.

Health care organizations continue to implement organization-wide educational approaches to enhance patient safety with less attention on evaluating the impact of these approaches. In this context, a study was conducted to measure the impact of an organization-wide patient safety network approach on patient safety event reporting. A time-series analysis with reported rates of adverse events (major and moderate), near misses, sentinel events, and incidents from 2 years prior through 13 months following implementation was conducted. Study findings include a significant increase in reporting of patient safety events (an approximately 50% increase in overall reporting of safety events was observed; p < .001), especially near misses (an approximately 100% increase following implementation; p = .002). Study findings suggest that a multifaceted networked approach does contribute to improving patient safety event reporting.

We aimed to evaluate the effect of pain education on opioid prescribing by early-career general practitioners. A brief training workshop was delivered to general practice registrars of a single regional training provider. The workshop significantly reduced "hypothetical" opioid prescribing (in response to paper-based vignettes) in an earlier evaluation. The effect of the training on "actual" prescribing was evaluated using a nonequivalent control group design nested within the Registrar Clinical Encounters in Training (ReCEnT) cohort study: 4 other regional training providers were controls. In ReCEnT, registrars record detailed data (including prescribing) during 60 consecutive consultations, on 3 occasions. Analysis was at the level of individual problem managed, with the primary outcome factor being prescription of an opioid analgesic and the secondary outcome being opioid initiation. Between 2010 and 2015, 168,528 problems were recorded by 849 registrars. Of these, 71% were recorded by registrars in the nontraining group. Eighty-two percentages were before training. Opioid analgesics were prescribed in 4382 (2.5%, 95% confidence interval [CI]: 2.40-2.63) problems, with 1665 of these (0.97%, 95% CI: 0.91-1.04) representing a new prescription. There was no relationship between the training and total prescribing after training (interaction odds ratio: 1.01; 95% CI: 0.75-1.35; P value 0.96). There was some evidence of a reduction in initial opioid prescriptions in the training group (interaction odds ratio: 0.74; 95% CI: 0.48-1.16; P value 0.19). This brief training package failed to increase overall opioid cessation. The inconsistency of these actual prescribing results with "hypothetical" prescribing behavior suggests that reducing opioid prescribing in chronic noncancer pain requires more than changing knowledge and attitudes.

Chronic pain is a growing problem with little obvious explanation for its increasing prevalence. Traditional medical approaches including pain-killing medications have been largely unsuccessful and potentially counterproductive in stemming this growth over the long term. Hence, a more holistic approach incorporating aspects of lifestyle and psychology has begun to be used in pain clinics and primary care, with an expanding role for the lifestyle medicine practitioner.

To evaluate whether a Post-Arrest Consult Team improved care and outcomes for patients with out-of-hospital cardiac arrest.Prospective cohort study of Post-Arrest Consult Team implementation at two hospitals, with concurrent controls from 27 others.Twenty-nine hospitals within the Strategies for Post-Arrest Care Network of Southern Ontario, Canada.We included comatose adult nontraumatic out-of-hospital cardiac arrest patients surviving more than or equal to 6 hours after emergency department arrival who had no contraindications to targeted temperature management.The Post-Arrest Consult Team was an advisory consult service to improve 1) targeted temperature management, 2) assessment for percutaneous coronary intervention, 3) electrophysiology assessment, and 4) appropriately delayed neuroprognostication.We used generalized linear mixed models to explore the association between Post-Arrest Consult Team implementation and performance of targeted processes. We included 1,006 patients. The Post-Arrest Consult Team was associated with a significant reduction over time in rates of withdrawal of life-sustaining therapy within 72 hours of emergency department arrival on the basis of predictions of poor neurologic prognosis (ratio of odds ratios, 0.13; 95% CI, 0.02-0.98). Post-Arrest Consult Team was not associated with improved successful targeted temperature management (ratio of odds ratios, 0.91; 95% CI, 0.31-2.65), undergoing angiography (ratio of odds ratios, 1.91; 95% CI, 0.17-21.04), receiving electrophysiology consultation (ratio of odds ratios, 0.93; 95% CI, 0.11-8.16), or functional survival (ratio of odds ratios, 0.75; 95% CI, 0.19-2.94).Implementation of a Post-Arrest Consult Team reduced premature withdrawal of life-sustaining therapy but did not improve rates of successful targeted temperature management, coronary angiography, formal electrophysiology assessments, or functional survival for comatose patients after out-of-hospital cardiac arrest.

Chronic pain has a significant economic and social impact on the community. The most common medical treatments for it include paracetamol, anti-inflammatory agents, and opioid analgesics. However, many of these medications cause side effects, and their long-term effectiveness is questionable. The traditional alternative to the biomedical approach is cognitive behavioral therapy. However, this has also been shown in recent studies to have only modest benefit. It is becoming clear that the effective management of chronic pain requires a more holistic, systems-based approach, hence the emerging interest in the relationship between pain and lifestyle. The authors aim to review the literature regarding the relationship between comprehensive lifestyle changes, markers of systemic inflammation, and the perception of chronic pain. An extensive search of bibliographic databases, including MEDLINE, PubMed, Web of Science, and Cochrane Library databases was made. A total of 2197 articles were identified using the search strategy. Only 44 articles were retrieved for critical appraisal, of which only 2 studies met the prespecified primary inclusion criteria and were included in the final review. These data provided some evidence that a single lifestyle factor (sleep restriction or disturbance) can produce elevated levels of interleukin-6, which is associated with higher pain intensity ratings. However, this review has highlighted a paucity of research based around the relationship between lifestyle, metaflammation, and chronic pain. There is a clear need for well-designed trials examining comprehensive lifestyle interventions and their effect on both pain intensity and markers of metaflammation.

BackgroundGPs are central to opioid strategy in chronic non-cancer pain (CNCP). Lack of treatment alternatives and providers are common reasons cited for not deprescribing opioids. There are limited data about availability of multidisciplinary healthcare providers (MHCPs), such as psychologists, physiotherapists, or dietitians, who can provide broader treatments.AimTo explore availability of MHCPs, and the association with GP opioid deprescribing and transition to therapeutic alternatives for CNCP.Design & settingCross-sectional survey of all practising GPs (N = 1480) in one mixed urban and regional Australian primary health network.MethodA self-report mailed questionnaire assessed the availability of MHCPs and management of their most recent patient on long-term opioids for CNCP.ResultsSix hundred and eighty-one (46%) valid responses were received. Most GPs (71%) had access to a pain specialist and MHCPs within 50 km. GPs’ previous referral for specialist support was significantly associated with access to a greater number of MHCPs (P = 0.001). Employment of a nurse increased the rate ratio of available MHCPs by 12.5% (incidence rate ratio [IRR] 1.125, 95% confidence interval [CI] = 1.001 to 1.264). Only one-third (32%) of GPs reported willingness to deprescribe and shift to broader CNCP treatments. Availability of MHCPs was not significantly associated with deprescribing decisions.ConclusionLack of geographical access to known MHCPs does not appear to be a major barrier to opioid deprescribing and shifting toward non-pharmacological treatments for CNCP. Considerable opportunity remains to encourage GPs' decision to deprescribe, with employment of a practice nurse appearing to play a role.

In some cohort studies, a high-vegetable diet has been associated with greater likelihood of recurrence-free survival in women diagnosed with breast cancer. Carotenoids are obtained primarily from vegetables and fruit and they exhibit biological activities that may specifically reduce the progression of mammary carcinogenesis. The present analysis examines the relationship between plasma carotenoids at enrollment and 1, 2 or 3, 4, and 6 years and breast cancer–free survival in the Women's Healthy Eating and Living Study participants (N = 3,043), who had been diagnosed with early-stage breast cancer. The primary end point was time to a second breast cancer event (a recurrence or new primary breast cancer). An average carotenoid concentration over time was estimated for each participant as the average area under the plasma carotenoid curve formed by the plasma carotenoid concentrations at scheduled clinic visits. Multiple regression Cox proportional hazards analysis with adjustment for prognostic and other factors was used to examine the association between carotenoids and breast cancer–free survival. A total of 508 (16.7%) breast cancer events occurred over a median 7.12 years follow-up. Compared with the lowest tertile, the hazard ratio for the medium/high plasma carotenoid tertiles was 0.67 (95% confidence interval, 0.54-0.83) after adjustment. The interaction between the study group and tertile of average carotenoid concentration over time was not significant (P = 0.23). Higher biological exposure to carotenoids, when assessed over the time frame of the study, was associated with greater likelihood of breast cancer–free survival regardless of study group assignment.

Objective . To compare the outcomes of a new group assessment format with conventional individual assessment. Design . A randomized controlled trial. Setting . An Australian tertiary hospital multidisciplinary pain service. Patients . Adults referred with chronic non-cancer pain. Methods . Following attendance at an education and orientation group, 211 participants were randomized to either a group assessment format (focused on supported self-assessment) or individual assessment. Follow-up occurred 3 months post-assessment and prior to subsequent pain service intervention. Outcome measures were pain intensity, pain interference, self-efficacy, psychological distress, health care utilization beyond the pain service, waiting time, participant satisfaction, and implementation of self-management strategies. Results . Seventy-two participants undertook group assessment and 90 were assessed individually. Follow-up data were collected on 57 group and 72 individual assessment participants. Results revealed no significant differences between the two assessment formats in outcome with the exception of wait-times. Median wait-time to the first offer of assessment was 47 days for the group format and 144 days for individual. Conclusions . Group assessment provides a viable alternative to conventional individual assessment. The group assessment reduced wait-times while delivering otherwise comparable outcomes.

Traditionally the focus of Acute Pain Services (APSs) has been in the management of nociceptive pain. The recognition and management of neuropathic pain has been neglected. The aim of this study was to define the incidence of neuropathic pain in an Acute Pain Service population and to assess the risk of progression of these patients to persistent pain states. We report an incidence of acute neuropathic pain as 1–3% in patients seen by our APS. At follow up 78% of the patients had ongoing pain at 6 months and 56% at 12 months. Although numerically small in terms of overall APS activity the acute neuropathic pain group is significant in terms of the high risk of progression to chronicity. Early recognition of patients with acute neuropathic pain is an important component of APS activity. Further work is needed to clarify the role of pre-emptive strategies and early intervention in modulating progression to chronicity.

Setting. The study was set in an Australian tertiary public hospital multidisciplinary pain center. Objectives. The objectives of the study were to describe the conceptual shift undertaken by a multidisciplinary team in moving from a traditional approach to an emerging paradigm in pain medicine and to describe the practical application of a whole-person model of care and report outcomes over the period 2003–2010. Design. The study design was descriptive, including a brief review of current evidence base, consideration of models of service delivery, and analysis of the impact of applying a new, whole-person model of care for persistent pain. Intervention. Since 2004, a series of changes led to significant health system redesign. The process involved development of a broader, whole-person understanding of the individual with pain and a more integrated approach to service delivery across the spectrum from community to tertiary care. Results. Broad trends in the period 2003–2010 included a modest reduction in referral rate, marked reduction in waiting times, more efficient staff utilization, inversion of the ratio of new assessments to review appointments, increased telephone contact with primary care, increased use of personalized pain management plans, reduced procedural interventions and increased attendance at and clinically significant gains from shorter and more flexible group programs. Conclusions. Changes to conceptual framework inevitably influence the practicalities of service delivery. The application of a whole-person model for persistent pain brought improved engagement with the individual in pain and more efficient delivery of care at a systems level.

We aimed to determine internal medicine residents' perceptions of the adequacy of their training to serve as in-hospital cardiac arrest team leaders, given the responsibility of managing acutely critically ill patients and with recent evidence suggesting that the quality of cardiopulmonary resuscitation provided in teaching hospitals is suboptimal.Cross-sectional postal survey.Canadian internal medicine training programs.Internal medicine residents attending Canadian English-speaking medical schools.A survey was mailed to internal medicine residents asking questions relating to four domains: adequacy of training, perception of preparedness, adequacy of supervision and feedback, and effectiveness of additional training tools.Of the 654 residents who were sent the survey, 289 residents (44.2%) responded. Almost half of the respondents (49.3%) felt inadequately trained to lead cardiac arrest teams. Many (50.9%) felt that the advanced cardiac life support course did not provide the necessary training for team leadership. A substantial number of respondents (40%) reported receiving no additional cardiac arrest training beyond the advanced cardiac life support course. Only 52.1% of respondents felt prepared to lead a cardiac arrest team, with 55.3% worrying that they made errors. Few respondents reported receiving supervision during weekdays (14.2%) or evenings and weekends (1.4%). Very few respondents reported receiving postevent debriefing (5.9%) or any performance feedback (1.3%). Level of training and receiving performance feedback were associated with perception of adequacy of training (r(2) = .085, p.001). Respondents felt that additional training involving full-scale simulation, leadership skills training, and postevent debriefing would be most effective in increasing their skills and confidence.The results suggest that residents perceive deficits in their training and supervision to care for critically ill patients as cardiac arrest team leaders. This raises sufficient concern to prompt teaching hospitals and medical schools to consider including more appropriate supervision, feedback, and further education for residents in their role as cardiac arrest team leaders.

Objective To report a case of laparoscopic ilioinguinal nerve damage due to direct trauma from a secondary trocar placed in the right iliac fossa. Design Case report and literature review. Setting Tertiary referral hospital in an Australian city. Conclusion Patients with ilioinguinal neuralgia present significant diagnostic and management problems. This report highlights the need for gynaecologists to have a knowledge of the anatomical relations of the inguinal nerves in the lower abdominal wall, so that iatrogenic injury can be avoided.

Nuclear medicine techniques were used to show that the peripheral lymphatics are under autonomic control in much the same way as the blood vessels that supply the same anatomic region.Three patients with complex regional pain syndrome type 1 (reflex sympathetic dystrophy) involving a lower extremity were evaluated using three-phase bone scintigraphy and peripheral lymphoscintigraphy. Each patient was treated with ipsilateral chemical lumbar sympathectomy, and lymphoscintigraphy was repeated within several days of the procedure.All three patients had evidence of decreased flow (compared with the contralateral extremity) to normal flow after ipsilateral sympathectomy. Bone scintigraphy, before and after sympathectomy, was difficult to interpret because of the effects of altered weight bearing. Two patients who had unilateral peripheral edema showed marked improvement after sympathectomy and increased lymphatic flow.Peripheral lymphatic function is controlled by the autonomic nervous system. In reflex sympathetic dystrophy, peripheral edema may be caused by an increased sympathetic stimulus to the lymphatics. Further study of this phenomenon may show that nuclear medicine studies, such as bone scintigraphy and lymphoscintigraphy, can be used to distinguish patients who will benefit from sympathectomy from those who will not, thereby obviating invasive testing and unnecessary invasive treatment.

The presence of neuropathic pain in the postoperative period may be associated with unnecessary suffering, particularly if the diagnosis is not made and treatment modalities chosen are ineffective. It is likely that inadequate management of acute pain may set the scene for progression to a chronic pain state. The underlying neurobiological mechanisms whereby short-term stimuli may lead to long-term plasticity and structural changes in the nociceptive pathways are now being unraveled. The possibility arises that acute, intensive intervention may avoid or significantly reduce the development of these changes and subsequent chronic pain. Early diagnosis and treatment becomes a priority. There is a need for further research in this area to determine whether or not such theoretical potential can be turned to therapeutic advantage.

Objective To report long term experience (1997–2009) of intrathecal (IT) therapy for chronic non-cancer pain in the context of our team’s increasing emphasis on active management. Design Descriptive case series. Setting Australian tertiary multidisciplinary pain center, Hunter Integrated Pain Service (HIPS). Intervention This case series reports the changing use of IT implanted drug delivery systems (IDDSs) for chronic non-cancer pain over 13 years. Initially IT therapy was used selectively following multidisciplinary assessment and double blind IT trial. Typical therapy combined opioid with clonidine. Multidimensional management was offered. Treatment strategy changed in 2003 due to HIPS experience of limited therapeutic gains and equivocal support for IT therapy in the literature. Subsequently IT therapy was no longer initiated for non-cancer pain and those on established regimes were encouraged to shift to oral/transdermal opioids with greater emphasis on active management. Patient education and consultation were key elements. Where IT cessation was elective gradual dose reduction commenced as an outpatient. In elective and urgent cases ketamine infusion and oral clonidine were used during hospital admissions to cover the switch to oral/transdermal opioids. Over the study period transition occurred to a broader management framework in which IT therapy for chronic non-cancer pain was no longer supported by HIPS. Results 25 patients were managed using IDDSs; 8 implanted by HIPS and 17 by other teams. Dose escalation and adverse effects were common. 24 of 25 patients ceased IT therapy; 7 (29%) with urgent IDDS related complications, 16 (67%) electively and 1 due to an unrelated death. The remaining patient returned to her original team to continue IT therapy. One post-explantation patient transferred to another team to recommence IT therapy. The remainder were successfully maintained on oral/transdermal opioids combined with active management.

A hypo-osmolar medium and tissue processing technique is described which is useful for disaggregation of residual human tumor cell clumps persisting after mechanical or enzymatic treatment of solid tumors and malignant effusions. The addition of the hypo-osmolar procedure to the standard methods for disaggregation increased the viable single cell yield in solid tumors by 47% and in malignant effusions by 67%. In 5 of the 26 solid tumor specimens tested in the human tumor stem cell assay, clonogenic single cells were obtained with the hypo-osmolar procedure, whereas no growth was observed using standard methods. Overall, the success rate for clonogenicity increased from 46% to 65% for the 26 solid tumors, with the major improvement occurring in ovarian cancer. Clonogenicity was obtained in 80% of malignant effusions both by standard methods and the hypo-osmolar techniques. The increased total yield of clonogenic cells obtained with this procedure enhances the opportunity for experimental versatility and in vitro drug testing.
