A Global Survey of Ergonomics Practice Patterns and Rates of Musculoskeletal Pain Among Urologists Performing Retrograde Intrarenal Surgery

Retrograde intrarenal surgery (RIRS) requires awkward body posture for long durations. Few urologists receive ergonomics training despite the availability of ergonomics best practices utilized by other surgical specialties. We characterize ergonomics practice patterns and rates of musculoskeletal (MSK) pain among urologists performing RIRS. A web-based survey was distributed via the Endourological Society, the EAU, and social media. Surgeon anthropometrics and ergonomic factors were compared to ergonomics best practices. Pain was assessed with the Nordic Musculoskeletal Questionnaire (NMQ). Overall, 519 of 526 participants completed the survey (99% completion rate). Ninety-three percent of urologists consider ergonomic factors when performing RIRS to reduce fatigue (68%), increase performance (64%), improve efficiency (59%), and reduce pain (49%). Only 16% received ergonomics training. Residents/fellows had significantly lower confidence in ergonomic technique compared to attending surgeons of any career length. Adherence to proper ergonomic positioning for modifiable factors were highly variable. On NMQ, 12-month rates of RIRS-associated pain in ≥1 body part, pain limiting activities of daily living, and pain requiring medical evaluation were 81%, 51%, and 29%, respectively. Annual case volume >150 cases (OR 0.55 [0.35-0.87]) and higher adherence to proper ergonomic techniques (OR 0.67 [0.46-0.97]) were independently associated with lower odds of pain. Limitations include a predominantly male cohort which hindered the ability to assess gender disparities in pain and ergonomic preferences. Adherence to ergonomics best practices during RIRS is variable and may explain high rates of MSK pain among urologists. These results underscore the importance of utilizing proper ergonomic techniques and may serve as a framework for establishing ergonomics guidelines for RIRS.

Developing and testing a web-based intervention to support pain and symptom self-management in breast cancer surgery

Introduction: Surgery for breast cancer confers comorbidities including high rates of persistent post-surgical pain (PPSP). An audit revealed that the surgical pathway does not support patient self-management of symptoms. Web-based interventions (WBIs) have been shown to improve self-management in chronic conditions. A mixed-methods approach was used to develop a WBI to capture patient self-reported post-operative symptoms and provide individualised self-management advice.

Online Self-Management for Chronic Burn Pain: Results of a Randomized Controlled Trial

Following burn injury, survivors experience high rates of chronic pain and psychosocial concerns, including post-traumatic stress disorder (PTSD) and depression. Despite long-term pain and distress, survivors have limited access to effective pain psychology treatments after discharge in the United States. The current study compared the efficacy of an online self-management program for chronic pain after burn injuries to a time equivalent education control. The Take Charge of Burn Pain Recovery (TCBR-Pain) program involved seven online chronic pain coping modules based on cognitive-behavioral therapy. Adults at least six months post burn injury hospital discharge and experiencing pain greater than 3/10 severity were recruited and randomized into the TCBR-Pain (N = 47) or Control program (N = 49). Outcomes were assessed at pre-treatment, immediately post-treatment, 2-month, and 5-month follow-up. Full program completion was lower for the TCBR-Pain group (53%) relative to the Control group (90%). Linear models were fit to outcomes, adjusting for pre-treatment scores, adherence, and completion. On average, the TCBR-Pain group reported lower pain intensity relative to the Control group at post-treatment (MTCBR-Pain = 3.2, SDTCBR-Pain = 1.8; MControl = 4.1, SDControl = 1.9; p < .001). Among secondary outcomes, the TCBR-Pain group reported lower pain catastrophizing (MTCBR-Pain = 14.0, SDTCBR-Pain = 10.3; MControl = 17.6, SDControl = 11.8; p = .03) and borderline effects toward lower PTSD symptoms (MTCBR-Pain = 14.0, SDTCBR-Pain = 6.5; MControl = 16.0, SDControl = 6.1; p = .08) at post-treatment relative to the Control group. Although preliminary, these findings suggest online self-management programs can serve a role in delivering effective pain psychology interventions to survivors with chronic burn pain. The TCBR-Pain program attrition rate was higher than the Control program, but lower than typical e-health intervention attrition rates (60–80%). However, future research is needed to improve patient engagement in online pain self-management programs.

The Effect of Intraoperative Infusion of Dexmedetomidine on Acute and Chronic Postoperative Pain After Simple Mastectomy: A Randomized Double-Blind Clinical Trial

Background: Postoperative pain is a common expected problem. Appropriate medications are important to control pain, especially in breast cancer surgery with a high rate of postoperative acute and chronic pain. Objectives: This study aimed to evaluate the effect of intraoperative infusion of dexmedetomidine on acute and chronic pain after simple mastectomy. Methods: This is a double-blind clinical trial study which included 110 eligible patients for simple mastectomy from Shahid Faghihi Educational and Medical Center in Shiraz between October 2018 and May 2019. The patients were randomized into two groups of intervention who were received intraoperative dexmedetomidine 0.4 μg/kg/h, and control group who were received the same amount of placebo (normal saline 0.9%). The severity of acute and incidence of chronic pain were assessed with VAS of pain, and brief pain inventory (BPI), and the number of analgesics (Apotel, Morphine) that patients received in first 24 hours were recorded postoperatively. Collected data were analyzed, and P-values of less than 0.05% were considered statistically significant. Results: Here, 110 patients (55 people in each group) were met the inclusion criteria of the study. Based on the result of this study, the mean VAS score of pain in the intervention group (0.96 ± 0.14) was significantly lower than the control group (4.44 ± 2.25) (P &lt; 0.001). Although the incidence of chronic pain was different between the two groups after three months, this difference was not statistically significant (P = 0.871). Moreover, the number of requests and the amount of analgesia (Apotel and Morphine) in the first 24 hours after surgery in patients in the intervention group was significantly less than patients in the control group (P &lt; 0.001). Also, the time of the first request for analgesia (Apotel, Morphine) in the patients of the intervention group was significantly longer than the control group (P-value = 0.036). Conclusions: According to the finding of this study, the use of dexmedetomidine during simple mastectomy reduces pain, decreases, and delays in requirement of analgesia at the first 24 hours post-operation. However, it did not have a significant effect on chronic pain.

Attitudes Toward a Pre-authorized Concealed Opioid Taper: A Qualitative Analysis of Patient and Clinician Perspectives.

Standard opioid tapers tend to be associated with increased patient anxiety and higher pain ratings. Pre-authorized concealed opioid reductions may minimize expectations such as fear of increased pain due to the reduction of opioids and, prolong analgesic benefits in experimental settings. We recently observed that patients and clinicians are open to concealed opioid tapering. However, little is known about the “why” behind their attitudes. Based on this lack of data, we analyzed qualitative responses to survey questions on patients' and clinicians' acceptance of a concealed opioid reduction for chronic pain. Seventy-four patients with a history of high dose opioid therapy and 49 clinicians completed a web-based questionnaire with open-ended questions examining responses to two hypothetical clinical trials comparing a concealed opioid reduction pre-authorized by patients vs. standard tapering. We used content analysis based on qualitative descriptive methodology to analyze comments from the patients and clinicians. Five themes were identified: informed consent; anxiety; safety; support; and ignorance is bliss, or not. These themes highlight the overall positive attitudes toward concealed opioid tapers. Our findings reinforce the importance of patient-centered care and are expected to inform the design of clinical trials from both the patient and clinician perspective. This qualitative study presents patients' and clinicians' attitudes toward hypothetical scenarios for a trial of pre-authorized reduction of opioids. The findings indicate positive attitudes and the relevance of engaging patients with effective decision-making processes.

Randomised controlled trial: standard lightweight mesh vs self-gripping mesh in Lichtenstein procedure

&lt;b&gt; Introduction:&lt;/b&gt; Lichtenstein hernioplasty has been a gold standard of hernioplasty for 30 years now. However, the procedure may be followed by an unacceptably high rate of chronic pain, numbness and discomfort. &lt;/br&gt;&lt;/br&gt; &lt;b&gt;Aim:&lt;/b&gt; To compare outcomes of Lichtenstein repair using a Parietene ProGrip self-fixing mesh versus the standard lightweight macroporous mesh. &lt;/br&gt;&lt;/br&gt; &lt;b&gt;Material and methods:&lt;/b&gt; As many as 141 patients with unilateral primary inguinal hernia participated in this single-centre, randomised, prospective, single-blind (patient-blinded) study. Randomisation yielded two treatment groups: control group of 88 patients treated with Lichtenstein method using lightweight standard mesh (LS) and study group of 53 patients receiving treatment with self-fixing mesh (PG). Patients were followed up for 6 months. Primary outcome was the presence and severity of postoperative pain at discharge, at 30 days and 6 months post-procedure. Other study parameters were: duration of the procedure, duration of hospitalisation, presence of early and late complications, time needed to return to full activity and patient satisfaction. &lt;/br&gt;&lt;/br&gt; &lt;b&gt;Results:&lt;/b&gt; No statistically significant differences in pain severity were demonstrated at discharge or at long-term follow-up. In the first 30 days post-procedure the patients in the PG group complained of pain of greater severity on the NRS (2.0 vs 1.4) (P = 0.0466). The duration of the procedure in the PG group was 9.4 minutes shorter than in the LS group (P = 0.0027). No statistically significant differences between the groups were found in other studied parameters. &lt;/br&gt;&lt;/br&gt;&lt;b&gt;Conclusions:&lt;/b&gt; Self-fixing mesh can be safely used in inguinal canal repair procedures. It significantly shortened the duration of the procedure but at the same time did not reduce the severity of pain, including the rate of chronic postoperative inguinal pain.

Prevalence of medical and nonmedical cannabis use among veterans in primary care.

This study examined past-year cannabis use prevalence and sociodemographic and clinical correlates of cannabis use among Veterans Health Administration (VHA) primary care patients in a state with legalized medical cannabis. Participants were 1,072 predominantly white, male, VHA primary care patients enrolled in a drug screening validation study (2012-2014). Sociodemographic and clinical correlates were examined by past-year cannabis use status. Multivariate regression models, adjusted for demographics, estimated cannabis use prevalence and clinical correlates among recreational, medical, and both medical and recreational users. Nearly one in five (18.7%) veterans endorsed past-year cannabis use, with 14.1% of the total sample reporting any recreational use and 7.0% reporting any medical use. Correlates of any past-year use included younger age, period of service, being unmarried, lower education, lower income, other substance use, meeting criteria for an alcohol or drug use disorder or posttraumatic stress disorder, higher pain rating, and lower self-reported well-being. Compared to veterans endorsing only recreational use, veterans endorsing only medical use reported more cannabis use days but had lower odds of other drug use, alcohol or drug-related problems, or alcohol or drug use disorders. Differences between recreational only users and those using medical and recreational cannabis were minimal. Veterans enrolled in VHA in states with legalized cannabis may be particularly likely to use cannabis. Veterans identifying as recreational users may be at increased risk for adverse clinical outcomes compared to medical-only users. Prevalence monitoring, assessment, and intervention services should be considered, particularly in states with legalized cannabis. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

Demographic, military, and health comorbidity variables by mild TBI and PTSD status in the LIMBIC-CENC cohort

ABSTRACT Objective To describe associations of demographic, military, and health comorbidity variables between mild traumatic brain injury (mTBI) history and posttraumatic stress disorder (PTSD) status in a sample of Former and current military personnel. Setting Participants recruited and tested at seven VA sites and one military training facility in the LIMBIC-CENC prospective longitudinal study (PLS), which examines the long-term mental health, neurologic, and cognitive outcomes among previously combat-deployed U.S. Service Members and Veterans (SM/Vs). Participants A total of 1,540 SM/Vs with a history of combat exposure. Data were collected between 1/1/2015 through 3/31/2019. Design Cross-sectional analysis using data collected at enrollment into the longitudinal study cohort examining demographic, military, and health comorbidity variables across PTSD and mTBI subgroups. Main Measures PTSD Checklist for DSM-5 (PCL-5), mTBI diagnostic status, Patient Health Questionnaire 9-item (PHQ-9), Pittsburgh Sleep Quality Index (PSQI), AUDIT-C, and other self-reported demographic, military, and health comorbidity variables. Results Ten years following an index date of mTBI exposure or mid-point of military deployment, combat-exposed SM/Vs with both mTBI history and PTSD had the highest rates of depression symptoms, pain, and sleep apnea risk relative to SM/Vs without both of these conditions. SM/Vs with PTSD, irrespective of mTBI history, had high rates of obesity, sleep problems, and pain. Conclusion The long-term symptom reporting and health comorbidities among SM/Vs with mTBI history and PTSD suggest that ongoing monitoring and intervention is critical for addressing symptoms and improving quality of life.

Pain severity scores for common equine disorders as provided by horse owners and equine veterinarians.

Understanding factors influencing assessment of pain in horses will facilitate communication between veterinarians and horse owners. To compare estimates of pain experienced by horses as provided by veterinarians and horse owners and to determine factors associated with individuals who perceive horses to be experiencing extreme pain or minimal pain. Cross-sectional study. Internet-based questionnaires for horse owners and veterinarians included items related to recognition of pain in horses, estimated degree of pain experienced by horses, and demographic information. Variables associated with perception of a high or low degree of pain were investigated using logistic regression analyses. Final data sets included responses from 553 horse owners and 263 veterinarians. Pain scores varied widely and differences in median scores from horse owners and veterinarians were small. Horse owners providing high pain ratings were more likely to have <10 horses (odds ratio [OR]=2.0, 95% CI=1.1-3.5) and to not have a college degree (OR=1.5, 95% CI=1.0-2.2). Those providing low pain ratings were less likely to own <10 horses (OR=0.6, 95% confidence interval [CI]=0.4-0.9). Veterinarians providing high pain ratings were more likely to be employed in a mixed animal practice (OR=2.8, 95% CI=1.3-5.9) and to lack board-certification in a veterinary specialty (OR=2.1, 95% CI=1.1-4.2). Veterinarians providing low pain ratings were more likely to be male (OR=2.4, 95% CI=1.3-4.2). The respondent population may be biased because of the method of questionnaire distribution and associated sampling bias. Respondents were primarily from the United States. Assessments of the degree of pain horses are experiencing vary widely among horse owners and equine veterinarians.

Nonoperative management of anterior shoulder instability can result in high rates of recurrent instability and pain at long-term follow-up.

Data on the long-term outcomes of nonoperative treatment of anterior shoulder instability are lacking, particularly for the US population. The purpose was to (1) describe the characteristics of patients with anterior shoulder instability treated nonoperatively, (2) assess the long-term outcomes of nonoperative management in a US population, and (3) identify risk factors for poor outcomes following nonoperative management. A geographic cohort of >500,000 subjects was used to identify patients treated nonoperatively for anterior shoulder instability. Only patients aged <40 years at the time of initial instability with minimum 10-year follow-up were included. Medical records were reviewed to obtain demographic characteristics, physical examination findings, clinical history data, imaging results, treatment details, and clinical and/or radiographic progression. Recurrent pain, recurrent instability, and the development of symptomatic osteoarthritis (OA) were the primary outcomes evaluated. The study included 254 patients (73% male) with a median age of 19 years (range, 16-26 years) at the time of initial instability. At median 17-year follow-up, 37.5% experienced recurrent instability, 58.4% had recurrent pain, and 12.2% had symptomatic OA development. Factors associated with recurrent pain at final follow-up were multiple instability events prior to presentation (hazard ratio [HR], 2.43; P < .01) and increased pain at the initial visit (HRs of 0.79 for mild, 1.74 for moderate, and 1.39 for severe; P < .01); patients with multiple instability events prior to presentation also had an increased risk of recurrence (P < .01). Factors increasing the risk of the development of symptomatic OA included increased pain at the initial visit (P = .05), seizure disorder (HR, 27.01; P< .01), and smoking (HR, 5.15; P < .01). At long-term follow-up of 17 years, a high rate of poor outcomes was observed following nonoperative management of anterior shoulder instability. Overall, 37.5% of patients experienced recurrent shoulder instability, 58.4% had recurrent shoulder pain, and 12.2% had symptomatic OA development. Risk factors associated with adverse clinical outcomes included increased pain at the initial visit, recurrent instability prior to presentation, seizure disorder, and smoking.

The Relationship Between Experienced Discrimination and Pronociceptive Processes in Native Americans: Results From the Oklahoma Study of Native American Pain Risk

Native Americans (NAs) have higher pain rates than the general U.S. population. It has been found that increased central sensitization and reduced pain inhibition are pronociceptive processes that increase pain risk; yet, little attention has focused on the influence of psychosocial factors. Discrimination is a psychosocial factor associated with increased pain in other minoritized groups; however, it is unclear whether it also promotes pain in NAs. This study analyzed data from 269 healthy, pain-free participants (N = 134 non-Hispanic whites [NHWs], N = 135 NAs) from the Oklahoma Study of Native American Pain Risk. Experienced discrimination was measured using the Everyday Discrimination Scale (EDS). Nociceptive processes were measured via static measures of spinal sensitivity (nociceptive flexion reflex [NFR] threshold, 3-stimulation NFR threshold), temporal summation of pain (TS-Pain) and nociceptive flexion reflex (TS-NFR), and conditioned pain modulation of pain (CPM-Pain) and NFR (CPM-NFR). Results demonstrated that greater discrimination was associated with enhanced TS-NFR and impaired CPM-NFR but not static measures of spinal sensitivity or measures of pain modulation (TS-Pain, CPM-Pain). Although the effects of discrimination on outcomes were similar in both groups (not moderated by ethnicity), NAs experienced higher levels of discrimination and therefore discrimination mediated a relationship between ethnicity and impaired CPM-NFR. This indicates experienced discrimination may promote a pain risk phenotype in NAs that involves spinal sensitization resulting from impaired inhibition of spinal nociception without sensitization of pain experience. PerspectiveThis study found that discrimination was associated with spinal sensitization and impaired descending inhibition of spinal nociception. These findings bolster our understanding of how social stressors experienced disproportionately by minoritized groups can contribute to pain outcomes.

Burden of disease of X-linked hypophosphatemia in Japanese and Korean patients: a cross-sectional survey.

The burden of disease of X-linked hypophosphatemia (XLH) in East Asia is poorly understood. This was a cross-sectional study using an online questionnaire to evaluate health-related quality of life (HRQOL) and disease complications in Japanese and Korean patients with XLH. Adults with XLH and the caregivers of children <18 years of age with XLH in Japan and Korea were surveyed. Respondents disclosed demographic data, family history, diagnostic history, medical history, surgical history, disease-specific clinical symptoms, treatment, medications, and use of ancillary equipment. Patient-reported outcomes (PROs; the Western Ontario and McMaster Universities Osteoarthritis Index, the brief pain inventory, and the 36-item short form health survey version 2) were used to assess pain, disability, and HRQOL in adults. Of those surveyed, all 14 children (100%) and 30/32 adults (93.8%) were receiving treatment for XLH. However, despite oral phosphate and active vitamin D use, short stature, gait abnormalities, dental conditions, and decreased physical function were reported. Stapling of the growth plates was reported in 14.3% of children but no adults. Adult patients reported high rates of bone pain (59.4%) and joint pain (65.6%). Caregivers of children with XLH also reported the occurrence of bone pain (35.7%) and joint pain (35.7%). Many adult patients had a history of impaired renal function (9.5%), nephrocalcinosis (15.6%), hyperparathyroidism (15.6%), and parathyroidectomy (6.3%), all of which are associated with conventional XLH treatments. These data show that patients (both pediatric and adult) continue to have symptoms such as pain, disability, and various complications despite receiving conventional therapies.

Trajectories, Risk Factors, and Impact of Persistent Pain After Major Musculoskeletal Surgery in Adolescents: A Replication Study

Studies have identified high rates of chronic postsurgical pain in adolescents. Characterizing patterns of pain in the transition from acute to chronic following major surgery may pinpoint critical periods of recovery. This observational study modelled pain trajectories over 1-year following surgery to attempt replication of prior work and evaluate baseline psychosocial factors and 12-month health outcomes. Adolescents 10 to 18 years completed electronic daily pain reporting for 7 days and self-reported health outcomes, at 5 assessment timepoints. Group-based trajectory modelling identified two trajectories with similar starting points in-hospital but distinct recovery courses at home. Pain declined steadily in one group across the study period ("Declining Pain"; estimated probability,18.9%), but pain increased after hospital discharge and remained high through 12-months in the other group ("High and Persistent Pain"; estimated probability,81.1%). Pre-surgery pain (Aor=1.86, P=.001) and sleep quality (Aor=0.49, P=.029) were associated with the High and Persistent pain trajectory in multivariate regressions. This trajectory was associated with lower total quality of life (B=-9.79, P=.002), physical health (B=-15.93, P < .001), psychosocial health (B=-6.73, P=.06), and greater fatigue (B=-13.61, P=.001). This study replicated prior findings identifying two post-surgical pain trajectories with diverging pain in the first two weeks. Clinical detection of those with increasing pain and early intervention may interrupt persistence of pain. PERSPECTIVE: This article replicates a prior study identifying distinct post-surgical pain trajectories, Declining Pain and High and Persistent Pain. The High and Persistent pain trajectory is associated with pre-surgery pain, pre-surgery sleep quality, and lower quality of life (total, physical, and psychosocial health as well as fatigue) at 12-month follow-up.

Pain Among African American Family Caregivers: Association With Health Outcomes

There have been few investigations of the role that adolescent cognitive ability might play in predicting physical resilience across the life course, including decreased risk of early mortality. Our limited knowledge of how multiple cognitive ability domains shape trajectories of longevity is due, in part, to a lack of aging cohorts with early life cognitive assessments, and family data that allow for examination of shared family and genetic characteristics that may play a role in cognitive ability-health links. We capitalized on data from the 1960 Project Talent high school cohort (n>360,000, born 1942-1946) and mortality data (n=22,584; 5,497 deceased) collected as part of two recent follow-ups, the Project Talent Twin & Sibling Study and the Project Talent Aging Study, to examine these potential associations. In 1960, ability was assessed in multiple cognitive domains (e.g., general aptitude, quantitative, reasoning). Mortality status was ascertained through 2016. Binary logistic generalized estimating equations with race, age, sex, and adolescent family SES covariates, indicated that each 1 standard deviation higher ability in multiple cognitive domains in adolescence predicted lower odds of earlier mortality (ORs of 0.79 - 0.87). Co-sibling control models indicated a similar pattern, suggesting that benefits associated with higher cognitive performance do not simply reflect shared environmental and genetic background, but may represent a direct protective effect. These findings indicate that better performance in multiple cognitive domains in adolescence, above and beyond the influence of genetic and family environmental factors, may be or point to modifiable protective factors against risk of early mortality.

Prognosis does not change the landscape: palliative home care clients experience high rates of pain and nausea, regardless of prognosis

BackgroundMost individuals who typically receive palliative care (PC) tend to have cancer and a relatively short prognosis (< 6 months). People with other life-limiting illnesses can also benefit from a palliative care approach. However, little is known about those who receive palliative home care in Ontario, Canada’s largest province. To address this gap, the goal of this project was to understand the needs, symptoms and potential differences between those with a shorter (< 6 months) and longer prognosis (6+ months) for individuals receiving PC in the community.MethodsA cross-sectional analysis was conducted using interRAI Palliative Care (interRAI PC) assessment data collected between 2011 and 2018. Individuals with a shorter prognosis (< 6 months; n = 48,019 or 64.1%) were compared to those with a longer prognosis (6+ months; n = 26,945) across several clinical symptoms. The standardized difference (stdiff), between proportions, was calculated to identify statistically meaningful differences between those with a shorter and longer prognosis. Values of the stdiff of 0.2 or higher (absolute value) indicated a statistically significant difference.ResultsOverall, cancer was the most prevalent diagnosis (83.2%). Those with a shorter prognosis were significantly more likely to experience fatigue (75.3% vs. 59.5%; stdiff = 0.34) and shortness of breath at rest (22.1% vs. 13.4%; stdiff = 0.23). However, the two groups were similar in terms of severe pain (73.5% vs. 66.5%; stdiff = − 0.15), depressive symptoms (13.2% vs. 10.7%; stdiff = 0.08) and nausea (35.7% vs. 29.4%; stdiff = 0.13).ConclusionsThese results highlight the importance of earlier identification of individuals who could benefit from a palliative approach to their care as individuals with a longer prognosis also experience high rates of symptoms such as pain and nausea. Providing PC earlier in the illness trajectory has the potential to improve an individual’s overall quality of life throughout the duration of their illness.

Surgeon Strength: Ergonomics and Strength Training in Cardiothoracic Surgery

With the high prevalence of musculoskeletal pain in surgeons and interventionalists, it is critical to analyze the impact of ergonomics on cardiothoracic surgeon health. Here, we review the existing literature and propose recommendations to improve physical preparedness for surgery both in and outside the operating room. For decades, cardiothoracic surgeons have suffered from musculoskeletal pain, most commonly in the neck, and back due to a lack of proper ergonomics during surgery. A lack of dedicated ergonomics curriculum during training may leave surgeons at a high predisposition for work-related musculoskeletal disorders. We searched PubMed, Google Scholar, and other sources for studies relevant to surgical ergonomics and prevalence of musculoskeletal disease among surgeons and interventionalists. Whenever possible, data from quantitative studies, and meta-analyses are presented. We also contacted experts and propose an exercise routine to improve physical preparedness for demands of surgery. To date, many studies have reported astonishingly high rates of work-related pain in surgeons with rates as high as 87% in minimally-invasive surgeons. Several optimizations regarding correct table height, monitor positioning, and loupe angles have been discussed. Lastly, implementation of ergonomics training at some programs have been effective at reducing the rates of musculoskeletal pain among surgeons. Surgical work-related stress injuries are more common than we think. Many factors including smaller incisions and technological advancements have led to this plight. Ultimately, work-related injuries are underreported and understudied and the field of surgical ergonomics remains open for investigative study.

Patterns, trends and determinants of medical opioid utilization in Canada 2005\u20132020: characterizing an era of intensive rise and fall

BackgroundInto the 21st century, the conflation of high rates of chronic pain, systemic gaps in treatment availability and access, and the arrival of potent new opioid medications (e.g., slow-release oxycodone) facilitated strong increases in medical opioid dispensing in Canada. These persisted until post-2010 alongside rising opioid-related adverse (e.g., morbidity/mortality) outcomes. We examine patterns, trends and determinants of opioid dispensing in Canada, and specifically its 10 provinces, for the years 2005–2020.MethodsRaw data on prescription opioid dispensing were obtained from a large national community-based pharmacy database (IQVIA/Compuscript), converted into Defined-Daily-Doses/1,000 population/day for ‘strong’ and ‘weak’ opioid categories per standard methods. Dispensing by opioid category and formulations by province/year was assessed descriptively; regression analysis was applied to examine possible segmentation of over-time strong opioid dispensing.ResultsAll provinces reported starkly increasing strong opioid dispensing peaking 2011–2016, and subsequent marked declines. About half reported lower strong opioid dispensing in 2020 compared to 2005, with continuous inter-provincial differences of > 100 %; weak opioids also declined post-2011/12. Segmented regression suggests breakpoints for strong opioids in 2011/12 and 2015/16, coinciding with main interventions (e.g., selective opioid delisting, new prescribing guidelines) towards more restrictive opioid utilization control.ConclusionsWe characterized an era of marked rise and fall, while featuring stark inter-provincial heterogeneity in opioid dispensing in Canada. While little evidence for improvements in pain care outcomes exists, the starkly inverting opioid utilization have been associated with extensive population-level harms (e.g., misuse, morbidity, mortality) over-time. This national case study raises fundamental questions for opioid-related health policy and practice.

Association of Lifetime History of Traumatic Brain Injury With Prescription Opioid Use and Misuse Among Adults

To investigate associations of lifetime history of traumatic brain injury (TBI) with prescription opioid use and misuse among noninstitutionalized adults. Ohio Behavioral Risk Factor Surveillance System (BRFSS) participants in the 2018 cohort who completed the prescription opioid and lifetime history of TBI modules (n = 3448). Secondary analyses of a statewide population-based cross-sectional survey. Self-report of a lifetime history of TBI using an adaptation of the Ohio State University TBI-Identification Method. Self-report of past year: (1) prescription pain medication use (ie, prescription opioid use); and (2) prescription opioid misuse, defined as using opioids more frequently or in higher doses than prescribed and/or using a prescription opioid not prescribed to the respondent. In total, 22.8% of adults in the sample screened positive for a lifetime history of TBI. A quarter (25.5%) reported past year prescription opioid use, and 3.1% met criteria for prescription opioid misuse. A lifetime history of TBI was associated with increased odds of both past year prescription opioid use (adjusted odds ratio [AOR] = 1.52; 95% CI, 1.27-1.83; P < .01) and prescription opioid misuse (AOR = 1.65; 95% CI, 1.08-2.52; P < .05), controlling for sex, age, race/ethnicity, and marital status. Results from this study support the "perfect storm" hypothesis-that persons with a history of TBI are at an increased risk for exposure to prescription opioids and advancing to prescription opioid misuse compared with those without a history of TBI. Routine screening for a lifetime history of TBI may help target efforts to prevent opioid misuse among adults.

A digital health peri-operative cognitive-behavioral intervention to prevent transition from acute to chronic postsurgical pain in adolescents undergoing spinal fusion (SurgeryPalTM): study protocol for a multisite randomized controlled trial

BackgroundSpinal fusion surgery is associated with severe acute postsurgical pain and high rates of chronic postsurgical pain in adolescents. Psychological distress, sleep disturbance, and low pain self-efficacy predict higher acute pain and likelihood of developing chronic postsurgical pain. Interventions targeting baseline psychosocial risk factors have potential to interrupt a negative trajectory of continued pain and poor health-related quality of life (HRQL) over time but have not yet been developed and evaluated. This randomized controlled trial will test effectiveness of a digital peri-operative cognitive-behavioral intervention (SurgeryPalTM) vs. education-control delivered to adolescents and their parents to improve acute and chronic pain and health outcomes in adolescents undergoing spine surgery.MethodsAdolescents 12–18 years of age undergoing spinal fusion for idiopathic conditions, and their parent, will be recruited from pediatric centers across the USA, for a target complete sample of 400 dyads. Adolescents will be randomized into 4 study arms using a factorial design to SurgeryPalTM or education control during 2 phases of treatment: (1) pre-operative phase (one-month before surgery) and (2) post-operative phase (1 month after surgery). Acute pain severity and interference (primary acute outcomes) and opioid use will be assessed daily for 14 days following hospital discharge. Chronic pain severity and interference (primary acute outcomes), as well as HRQL, parent and adolescent distress, sleep quality, and opioid use/misuse (secondary outcomes), will be assessed at 3 months and 6 months post-surgery.DiscussionDemonstration of effectiveness and understanding optimal timing of perioperative intervention will enable implementation of this scalable psychosocial intervention into perioperative care. Ultimately, the goal is to improve pain outcomes and reduce reliance on opioids in adolescents after spine surgery.Trial registrationNCT04637802 ClinicalTrials.gov. Registered on November 20, 2020

Pain and Functional Limitations Among Midlife and Older Canadians: The Role of Discrimination, Race and Sense of Belonging.

We drew on fundamental cause theory and the weathering hypothesis to examine how discrimination influences aging for midlife and older adults in Canada. Using nationally representative data, we assessed the associations between discrimination and pain and functional limitations among adults 45 years of age and older. Discrimination was measured using a modified version of the Everyday Discrimination Scale. Chi-square tests were performed to check for baseline differences in the dependent and key predictor variables by race. Logistic regression was used to estimate the associations of discrimination, race, and sense of belonging with pain and functional limitations, net of sociodemographic characteristics and SES. Indigenous respondents showed a clear health disadvantage, with higher rates of pain and functional limitations compared to Whites and Asians. Self-reported discrimination was also higher for Indigenous midlife and older adults than for their White and Asian age counterparts. Discrimination had a direct and robust association with pain (OR 1.56, 95% CI 1.31, 1.87) and functional limitations (OR 1.55, 95% CI 1.29, 1.87). However, race moderated the impact of discrimination on functional limitations for Blacks. Finally, a strong sense of belonging to one's local community was protective against pain and functional limitations for all racial groups. Future research needs to further examine the impact of discrimination on Indigenous peoples' aging process. High rates of discrimination coupled with a greater burden of pain means that Indigenous midlife and older adults may require additional and targeted health and social service resources to age successfully.
