Longitudinal relationships between anxiety, depression, and pain: results from a two-year cohort study of lower extremity trauma patients

Key components of rehabilitation programmes for adults with complex fractures following traumatic injury: A scoping review

INTRODUCTION

Complex fractures are severe injuries that cause considerable disability, particularly in the working population. Effective rehabilitation is essential to achieve good outcomes, however, it is unclear what the best rehabilitation strategy is for adults with complex fractures, after their discharge from hospital. The aim of this scoping review was to identify and map the breadth of evidence available on this topic.

METHODS

A systematic search was completed on 24th July 2023 using a combination of subject and specialist databases. In addition, a secondary search assessed unpublished literature from trial registries. A citation search was completed on the selected studies. The template for intervention description and replication (TIDieR) checklist was used to extract consistent data on the interventions reported in the studies. The Joanna Briggs Institute methodology for scoping reviews was followed.

RESULTS

19,253 studies were identified from the search strategy of which 25 studies met the eligibility criteria. Most interventions were exercise-based and delivered by physiotherapists. Some studies compared manual therapy treatments to other forms of physiotherapy or a placebo, whilst others investigated psychosocial interventions, such as cognitive behavioural therapy, in comparison to usual care. Two studies took a multidisciplinary team approach, incorporating components such as exercise, functional activities and self-management strategies.

DISCUSSION

The studies included were heterogenous in terms of population (fracture type, location and complexity), intervention content and therapeutic aims. However, commonalities were found with most interventions or comparators including range of movement, strengthening and task specific exercises; functional tasks; gait and balance training; and advice on return to activities as components. Value was attributed to components such as, a coordinated team approach, person-centred rehabilitation, supervised exercise and psychosocial support.

CONCLUSION

There is a broad and varied approach to the rehabilitation of complex fractures. The studies differed in population and approach, with a wide range of injuries, interventions and modes of delivery reported. Fidelity was poorly described, with only a third of studies reporting adherence or acceptability. There was inconclusive evidence to inform clinical practice and further research is advised. Qualitative, expert consensus, and coproduction approaches are recommended methods to develop complex interventions and best practice guidance.

Bidirectional relationship between chronic pain and depressive symptoms in middle-aged and older adults

OBJECTIVE

To assess the bidirectional association between chronic pain and depressive symptoms among middle-aged and older adults from two prospective cohort studies.

METHODS

We used prospective data (12y of follow-up) from the English Longitudinal Study of Ageing (n = 9149, 5018 women, 65.0 ± 10.2y) and the Health and Retirement Study (n = 16,883, 9810 women, 66.9 ± 10.3y), including data from seven waves of each cohort between 2006 and 2018/2019. Depressive symptoms were assessed using the Centre of Epidemiological Studies Depression scale, while chronic pain was estimated using questions about the frequency of being troubled with pain. We used random-intercept cross-lagged panel models to assess the bidirectional association between pain and depressive symptoms, adjusting for potential confounders.

RESULTS

There was a cross-lagged effect of chronic pain on depressive symptoms (ELSA: β: 0.038; 95%CI: 0.011-0.066. Standardized coefficient (B): 0.021.

SHARE

β: 0.044; 95%CI: 0.023-0.065. B: 0.023-0.024) as well as depressive symptoms on pain (ELSA: β: 0.010; 95%CI: 0.002-0.018. B: 0.017-0.019.

SHARE

0.011; 95%CI: 0.005-0.017. B: 0.020-0.021). Moreover, there were auto-regressive effects of both chronic pain (ELSA: β: 0.149; 95%CI: 0.128-0.171.

SHARE

β: 0.129; 95%CI: 0.112-0.145) and depressive symptoms (ELSA: β: 0.149; 95%CI: 0.130-0.168.

SHARE

β: 0.169; 95%CI: 0.154-0.184).

CONCLUSION

We identified a modest bidirectional association between depressive symptoms and chronic pain, using two large prospective ageing cohorts.

Anxiety, pain catastrophizing, and pain outcomes among older adults with chronic orofacial pain

Although chronic orofacial pain (COFP) is common among older adults, the role of psychological factors in pain outcomes among this population has received limited attention. This study examined the role of anxiety and pain catastrophizing, two corelates of pain in other populations, in pain intensity and interference among 166 older adults with COFP (79% female, Mage = 68.84, SD = 5.56). Participants completed an online survey including measures of anxiety, pain catastrophizing, and pain intensity/interference. We applied mediation analyses to test indirect associations between anxiety and pain outcomes via pain catastrophizing. Results indicated that anxiety was positively associated with pain intensity and pain interference (bs = .70-1.12, ps < .05). There was also an indirect association between anxiety and pain interference through pain catastrophizing (b = .35, 95% CI [.0383, .7954]), indicating pain catastrophizing partially accounts for this relationship. Assessing and addressing anxiety and pain catastrophizing has the potential to improve treatment outcomes in this population.

The association of pre-existing mental health conditions and patient outcomes after lower extremity orthopaedic trauma: a scoping review

INTRODUCTION

Existing research has established a correlation between post-traumatic mental health conditions, including anxiety and depression, and various aspects of recovery, such as pain exacerbations, reduced functional recovery, and lowered patient satisfaction. However, the influence of pre-existing mental health conditions on orthopaedic trauma outcomes has not been thoroughly investigated. The objective of this study was to systematically review literature addressing the association between pre-existing mental health conditions and patient outcomes following surgical interventions for lower extremity fractures in non-geriatric populations.

METHODS

A systematic literature review was conducted using Medline, Embase, and Scopus databases following PRISMA-ScR guidelines to select studies that examined lower extremity orthopaedic trauma outcomes in relation to pre-existing mental health conditions. Studies that evaluated patients with surgically treated lower extremity fractures and a history of mental health conditions such as anxiety, depression, or mood disorders were included. Studies with a mean patient age above 65 years of age were excluded to focus on non-geriatric injury patterns.

RESULTS

The systematic review identified 12 studies investigating the relationship between surgical outcomes of orthopaedic lower extremity fractures and pre-existing mental health disorders in non-geriatric populations. Studies included patients with pelvis, femur, tibia, and ankle fractures. A majority (83%) of these studies demonstrated that patients with pre-existing mental health diagnoses had inferior functional outcomes, heightened pain levels, or an increase in postoperative complications.

DISCUSSION

The presence of pre-existing mental health conditions, particularly anxiety and depression, may predispose orthopaedic trauma patients to an elevated risk of suboptimal functional outcomes, increased pain, or complications after surgical intervention for lower extremity fractures. Future research should focus on interventions that mitigate the impact of mental health conditions on orthopaedic outcomes and patient wellness in this population.

Mindful attention is inversely associated with pain via mediation by psychological distress in orthopedic patients

BACKGROUND

Orthopedic patients report pain as their main symptom complaint. Subjective pain experience is correlated with self-reported psychological state, such as distress.

PURPOSE

This study tests whether scores from a measure of mindful attention are associated with subjective pain levels and whether psychological distress scores function as a mediation path.

METHODS

During routine visits to a single orthopedic clinic in East Los Angeles, California, 525 patients were recruited to participate in the study. Participants reported on measures of pain (Universal Pain Assessment Tool [UPAT]), mindful attention (Five-Facet Mindfulness Questionnaire [FFMQ]), and psychological distress (Depression, Anxiety, Stress Scale [DASS]). We used Pearson correlations to examine relationships between FFMQ and UPAT scores and mediation analyses to test indirect effects of DASS scores as a mediation path.

RESULTS

The average age of the sample was 54 years (range 18-98 years), 61% were male, and 64% were non-Hispanic White individuals. The locations of injury were the shoulder (72%), elbow (21%), and clavicle or wrist (7%). Ninety-one percent reported mild or greater pain in the prior 2 weeks (mean = 4.2 ± 2.5, range 0-10), and 49% reported mild or more severe distress symptoms (DASS: 13.0 ± 11.5). FFMQ scores inversely predicted UPAT scores (β = -0.22, P < .01), mediated through DASS scores. DASS subscale scores for depression (β = -0.10, P = .02) and stress (β = -0.08, P = .04) but not anxiety (β = -0.03, P = .33) produced significant indirect effects. FFMQ acting-with-awareness and non-judging subscales had the largest effect on depression and stress DASS subscale scores.

CONCLUSIONS

We find statistical support to suggest that distress-particularly depressed mood and stress-mediates the association between mindful attention and pain intensity among orthopedic patients. A disposition of mindful attention might counter distress ailments that exacerbate subjective pain, and this has possible implications for mindfulness training interventions offered to orthopedic patients.

Psychological treatments for the management of pain after musculoskeletal injury: a systematic review and meta-analysis

ABSTRACT

Musculoskeletal injury is a leading cause of pain and disability worldwide; 35% to 75% of people experience persistent pain for months and years after injury. Psychological treatments can reduce pain, functional impairment, and psychological distress but are not widely used after injury. This systematic review and meta-analysis (PROSPERO ID: CRD42021236807) aimed to synthesize the literature testing psychological treatments for pain after musculoskeletal injury. We searched EMBASE, MEDLINE, PubMed, PsycINFO, and CENTRAL from inception to May 2022. We extracted participant, treatment, and injury characteristics and primary (eg, pain intensity, functional impairment, depression, anxiety, and PTSD symptoms) and secondary (treatment feasibility and acceptability) outcomes. Twenty-four randomized controlled trials (N = 1966) were included. Immediately posttreatment, people who received psychological treatments (versus any control) reported lower pain intensity (standardized mean differences [SMD] = -0.25, 95% confidence interval [-0.49, -0.02]), functional impairment (SMD = -0.32 [-0.55, -0.09]), and symptoms of depression (SMD = -0.46 [-0.64, -0.29]), anxiety (SMD = -0.34 [-0.65, -0.04]), and PTSD (SMD = -0.43 [-0.70, -0.15]); at 6-month follow-up, only depression symptoms were significantly lower. Included trials varied widely in treatment and injury characteristics. The certainty of evidence was low or very low for most effects and heterogeneity moderate to substantial. Most studies had risk of bias domains judged to be high or unclear. Owing to very low certainty of results, we are unsure whether psychological therapies reduce pain and functional impairment after musculoskeletal injury; they may result in improved depression immediately posttreatment and at follow-up. More research is needed to identify treatments that result in enduring effects.

Psychiatric disorders, personality traits, and childhood traumatic events predicting incidence and persistence of chronic pain: results from the CoLaus|PsyCoLaus study

ABSTRACT

Chronic pain (CP) is often accompanied by mental disorders (MDs). However, little is known concerning the long-term effect of MDs, personality traits, and early-life traumatic events (ETEs) on CP course. Accordingly, we aimed to prospectively assess the associations of major depressive disorders (MDDs), anxiety disorders, personality traits, and ETEs with the incidence and the persistence of CP in middle-aged and older community dwellers. Data stemmed from the 3 first follow-up evaluations of CoLaus|PsyCoLaus, a prospective cohort conducted in the general population of Lausanne (Switzerland). Diagnostic criteria for MDs and ETEs were elicited using semistructured interviews. CP and personality traits were assessed by self-rating questionnaires. Follow-up intervals were subdivided into 2 groups: those without (n = 2280) and those with (n = 1841) CP initially. The associations between the psychological variables and the occurrence or persistence of CP 5 years later were assessed using serially adjusted logistic regression models. Higher neuroticism (odds ratio [95% confidence interval] 1.21 [1.08; 1.36]) and extraversion (1.18 [1.06; 1.32]) were associated with higher 5-year CP incidence, whereas current (2.14 [1.34; 3.44]) and remitted MDD (1.29 [1.00; 1.66]) as well as lower extraversion (0.83 [0.74; 0.94]) were associated with persistence of CP. By contrast, ETEs and anxiety disorders were not associated with the incidence or persistence of CP. Our results suggest that personality traits are associated with both CP occurrence and persistence, whereas the MDDs may be more associated with CP persistence. Both personality and MDD are accessible to psychotherapy, and MDD is also accessible to pharmacotherapy. Hence, these therapeutic measures might decrease the risk of CP and its persistence.

Determining the clinical significance of the PROMIS physical function score in the setting of femur fractures

BACKGROUND

To adequately utilize patient reported outcome scores in the clinical setting, accurate determination of a cohort-specific minimal clinically important differences (MCID) is necessary. The purpose of this study was to assess MCID for Patient Reported Outcome Information System Physical Function Scores (PROMIS®) Physical Function (PF) in a sample of patients who have undergone operative fixation for femur fractures.

METHODS

All patients at a single Level 1 trauma center who were treated for operative femur fractures were identified by Current Procedural Terminology (CPT) codes (27,244, 27,245, 27,506, 27,507). PROMIS PF was collected as part of routine clinical care via computer adaptive testing (CAT). MCID calculations were performed using both anchor-based and distribution-based methods.

RESULTS

A total of 182 patients with 723 score observations were included in the overall distribution-based analysis and 131 patients with 309 score observations were included in the anchor-based analysis. In the overall cohort, the average age was 53.1 (SD 22.3), and 45% of participants were female. MCID for PROMIS PF scores was 5.43 in the distribution-based method and 5.18 in the anchor-based method. Overall scores in the distribution group improved from mean of 27.4 (SD 7.0) at the first postoperative visit to a mean of 36.7 (SD 10.0) at a subsequent follow up visit. Overall scores in the anchor group improved from mean of 26.7 (SD 7.3) at the first postoperative visit to a mean of 37.5 (SD 9.3) at a subsequent follow up visit.

CONCLUSIONS

This study identifies two MCID values (5.18, 5.43) based on two calculation methods for PROMIS physical function scores in the operative femur fracture population. This data could be helpful in targeting postoperative patients who fall below expected norms or in allowing clinical correlation with changes in surgical practice.

Patient-reported Anxiety Scores Are Associated With Lower Physical Function in Patients Experiencing Orthopaedic Trauma

BACKGROUND

The outcomes of orthopaedic trauma are not solely determined by injury severity or surgical treatment. Studies of numerous orthopaedic outcomes have found that psychosocial factors are also important. Symptoms of anxiety have been linked to long-term pain and disability. Although the existence of a relationship between psychosocial factors and functional outcomes is accepted across multiple disciplines, quantification of this association in patients who have experienced orthopaedic trauma has remained limited. Measuring the anxiety experienced by these individuals and the association with long-term functional outcomes remain poorly understood.

QUESTIONS/PURPOSES

(1) Is there an association between early postoperative anxiety symptoms and late recovery of self-reported physical function in patients with orthopaedic trauma? (2) What was the impact of other factors such as demographic variables and comorbidities on late recovery physical function scores, and how did the magnitude of these factors compare with the association with anxiety score? (3) Did patients who presented as trauma activations differ regarding their anxiety symptoms and late-recovery self-reported physical function?

METHODS

A total of 1550 patients with lower extremity fractures and postoperative Patient-Reported Outcomes Measurement Information System (PROMIS) anxiety and physical function scores treated between January 1, 2014, and January 1, 2021, at an academic Level I trauma center in North America were assessed. We performed a bivariate regression between the initial PROMIS anxiety and physical function, as well as a multivariate regression including age, gender, BMI, and American Society of Anesthesiologists class to control for potential confounding variables. In a subgroup of 787 patients presenting as trauma activations, we performed a separate regression including Injury Severity Score.

RESULTS

PROMIS anxiety was associated with decreased late-recovery physical function (β = -2.64 [95% CI -3.006 to -2.205]; p < 0.001). The relationship between PROMIS anxiety and physical function remained after controlling for confounding variables in our overall cohort (β = -2.54 [95% CI -2.93 to -2.15]; p < 0.001) and in the trauma activation cohort (β = -2.71 [95% CI -3.19 to -2.23]; p < 0.001). Age and American Society of Anesthesiologists score were associated with worse PROMIS physical function scores, while being a man was associated with better PROMIS physical function scores (age: β= -1.26 [95% CI -1.50 to -1.02]; American Society of Anesthesiologists class: β=-2.99 [95% CI -3.52 to -2.46]; men: β = 0.95 [95% CI 0.16 to 1.75]). There were no differences in initial anxiety symptoms or late-recovery physical function between patients who presented as trauma activations and those who did not. Injury Severity Scores were independently associated with worse function (β = -1.45 [95% CI -2.11 to -0.79].

CONCLUSION

Initial patient self-reported anxiety is negatively associated with patient-reported physical function at the final follow-up interval in a broad cohort of patients with orthopaedic lower extremity injuries undergoing surgery. Identifying patients with high initial PROMIS anxiety scores may allow us to determine which patients will report lower functional scores at the final follow-up. Future investigations could focus on the effect of psychosocial interventions such as cognitive behavioral therapy and mindfulness on functional scores.

The 12-Month Effects of the Trauma Collaborative Care Intervention: A Nonrandomized Controlled Trial

BACKGROUND

Studies have suggested that patient-centered collaborative care in the early phases of recovery may assist providers and patients in managing the multifactorial consequences of injury and may lead to better outcomes. This cluster-controlled trial, conducted at 12 U.S. Level-I trauma centers, was designed to evaluate the impact of the Trauma Collaborative Care (TCC) program on 1-year outcomes following severe musculoskeletal injury.

METHODS

Patients with high-energy orthopaedic trauma requiring surgical fixation were prospectively enrolled. Six sites implemented the TCC intervention as well as the Trauma Survivors Network (TSN), and the other 6 sites provided the standard of care. Participants were followed for 1 year, and a composite primary outcome measure composed of the Short Musculoskeletal Function Assessment (SMFA) Dysfunction Index, Patient Health Questionnaire-9 (PHQ-9), and Posttraumatic Stress Disorder Checklist (PCL) was assessed. A 2-stage, Bayesian hierarchical statistical procedure was used to characterize treatment effects. Sensitivity analyses were conducted to account for an error in the delivery of the intervention.

RESULTS

There were 378 patients enrolled at 6 trauma centers implementing the TCC program, and 344 patients enrolled at 6 trauma centers providing usual care. Patient utilization of treatment components varied across the intervention sites: 29% of patients in the intervention group received all 5 key components (TSN handbook education, peer visits, recovery assessment, and calls before and after recovery assessment). Posterior estimates of the intention-to-treat effect suggested that the intervention did not have an appreciable effect: the odds of the composite outcome for the TCC group increased by 5% (95% credible interval, -40% to 63%). The estimates of the effect of receiving all 5 key intervention components were similar.

CONCLUSIONS

Despite prior work showing early positive effects, this analysis suggests that the TCC program as delivered did not have positive effects on patient outcomes at 1 year. It is not known whether programs that improve compliance or target specific subgroups would better meet the psychosocial needs of trauma survivors.

Patient Mental Health and Well-being: Its Impact on Orthopaedic Trauma Outcomes

A patient's mental health can have a significant impact on their orthopaedic trauma outcome. It is important for orthopaedic surgeons to identify patients at risk for a poor outcome based on their mental health, to include the presence of post-traumatic stress disorder, depression, and anxiety, among others. Although some behaviors such as catastrophizing have been associated with worse outcomes, others, such as possessing greater self-efficacy have been associated with improved outcomes. Because of the high prevalence of mental health conditions that can have a detrimental effect on outcome, screening should be routinely conducted and at-risk patients referred to appropriate resources in an effort to optimize outcomes.

Musculoskeletal Pain Management and Patient Mental Health and Well-being

Orthopaedic trauma patients have high rates of psychiatric disorders, which put them at risk for worse outcomes after injury and surgery, including worse pain. Mental health conditions, such as depression and anxiety, can affect the perception of pain. Pain can also exacerbate or contribute to the development of mental illness after injury. Interventions to address both mental health and pain among orthopaedic trauma patients are critical. Balancing safety and comfort amid a drug overdose epidemic is challenging, and many clinicians do not feel comfortable addressing mental health or have the resources necessary. We reviewed the literature on the complex relationship between pain and mental health and presented examples of scalable and accessible interventions that can be implemented to promote the health and recovery of our patients. Interventions described include screening for depression in the orthopaedic trauma clinic and the emergency department or inpatient setting during injury and using a comprehensive and evidence-based multimodal pain management regimen that blends pharmacologic alternatives to opioids and physical and cognitive strategies to manage pain.

Trauma System Support to Facilitate Recovery

SUMMARY

Trauma is a major public health issue. Orthopaedic trauma surgeons are skilled in the acute management of musculoskeletal injury; however, formal training and resources have not been devoted to optimizing recovery after trauma. Recovery entails addressing the biomedical aspects of injury, as well as the psychological and social factors. The purposes of this study were to describe existing programs and resources within trauma centers, developed to promote psychosocial recovery. Supporting research data will be referenced, and potential barriers to program implementation will be discussed. The American College of Surgeons has mandated screening and treatment for mental illness after trauma, which will raise the bar to highlight the importance of these social issues, likely enabling providers to develop new programs and other resources within their systems. Provider education will promote the informing of patients and families, with the intent of enhancing the efficiency and scope of recovery.

Prevalence of dry eye disease among Chinese high school students during the COVID-19 outbreak

Purpose

The study aimed to investigate the prevalence of dry eye disease (DED) and relevant risk factors among Chinese high school students during the COVID-19 outbreak.

Methods

A cross-sectional study was conducted from November to December 2020, and 4825 high school students from nine high schools in Shanghai were recruited. All students completed ocular surface disease index (OSDI) and perceived stress scale (PSS) questionnaires and answered other questions designed to ascertain information on the risk factors related to DED. DED was diagnosed when OSDI scores were greater than or equal to 13. The prevalence of symptomatic DED was determined. A T-test, Kruskal-Wallis test, Chi-square test, and logistic regression analysis were used to examine the possible risk factors.

Results

The prevalence of symptomatic DED among Chinese high school students was 70.5%. In univariate analysis, higher PSS scores (P<0.001), prolonged video display terminal (VDT) use (P<0.001), wearing contact lenses (P=0.001), poor sleep quality (P<0.001), and being female (P<0.001) were significantly correlated with dry eyes. In multivariate logistic regression analysis, higher PSS scores (P<0.001, OR=1.20), prolonged VDT use (P<0.001, OR=1.07), poor sleep quality (P<0.001, OR=1.84), and being female (P=0.001, OR=1.25) were significant risk factors associated with DED.

Conclusions

Due to the epidemic, most Chinese high school students are in a high-risk environment in which they are more likely to suffer from DED, such as long online courses and heavy stress from school. Relevant preventive measures that may have a positive impact on public health and quality of life for high school students should be brought to the forefront.

Reciprocal Effects Between Depressive Symptoms and Pain in Veterans over 50 Years of Age or Older

OBJECTIVE

Depression and chronic pain are major problems in American veterans, yet there is limited long-term research examining how they relate to one another in this population. This study examined the relationship between depressive symptoms and pain in U.S. veterans 50 years of age or older.

METHODS

This study used data on veterans from the 2002-2016 waves of the Health and Retirement Study (n = 4,302), a large-scale observational study of Americans 50 years of age or older. Measures included a short form of the Center for Epidemiologic Studies Depression scale and two items assessing the presence and degree of pain. Analyses included random-intercept cross-lagged panel models (RI-CLPM).

RESULTS

In the RI-CLPM, there were roughly equivalent cross-lagged effects between depressive symptoms and pain. There was also evidence that depressive symptoms and pain have a trait-like component and that these trait-like characteristics are associated.

CONCLUSIONS

These findings indicate that depressive symptoms and pain in veterans are stable characteristics in American veterans 50 years of age or older. There appear to be reciprocal effects between the two, whereby deviations in one's typical depressive symptoms predict subsequent deviations in one's pain level and vice versa; however, the size of these effects is very small. These findings suggest that clinicians should treat both depressive symptoms and pain, rather than assume that treatment benefits in one domain will lead to major benefits in another.

What Is Important to Patients Who Are Recovering From an Open Tibial Fracture? A Qualitative Study

BACKGROUND

Open tibial fracture research has traditionally focused on surgical techniques; however, despite technological advances, outcomes from these injuries remain poor, with patients facing a sustained reduced quality of life. Research has rarely asked patients what is important to them after an open tibial fracture, and this question could potentially offer great insight into how to support patients. A qualitative study may assist in our understanding of this subject.

QUESTIONS/PURPOSES

We asked: (1) What common themes did patients who have experienced open tibial fractures share? (2) What stresses and coping strategies did those patients articulate? (3) What sources for acquiring coping strategies did patients say they benefited from?

METHODS

Semistructured interviews were conducted with patients who had sustained an open tibial fracture between January 1, 2016 and January 1, 2019. All participants were recruited from a Level 1 trauma center in England, and 26 participants were included. The mean age was 44 ± 17 years, and 77% (20 of 26) were men. The patients' injuries ranged in severity, and they had a range of treatments and complications. Transcripts were analyzed using framework analysis, with codes subsequently organized into themes and subthemes.

RESULTS

Four themes were identified, which included recouping physical mobility, values around treatment, fears about poor recovery, and coping strategies to reduce psychological burden. Coping strategies were important in mitigating the psychological burden of injury. Task-focused coping strategies were preferred by patients and perceived as taking a proactive approach to recovery. Healthcare practitioners, and others with lived experience were able to educate patients on coping, but such resources were scant and therefore probably less accessible to those with the greatest need.

CONCLUSION

Most individuals fail to return to previous activities, and it is unlikely that improvements in surgical techniques will make major improvements in patient outcomes in the near future. Investment in psychosocial support could potentially improve patient experience and outcomes. Digital information platforms and group rehabilitation clinics were identified as potential avenues for development that could offer individuals better psychosocial support with minimal additional burden for surgeons.

AAOS/Major Extremity Trauma and Rehabilitation Consortium Clinical Practice Guideline Summary for Evaluation of Psychosocial Factors Influencing Recovery From Orthopaedic Trauma

The Clinical Practice Guideline for Evaluation of Psychosocial Factors Influencing Recovery from Adult Orthopaedic Trauma is based on a systematic review of current scientific and clinical research. The purpose of this clinical practice guideline is to improve outcomes after adult orthopaedic trauma by evaluating, and addressing, the psychosocial factors that affect recovery. This guideline contains one recommendation to address eight psychosocial factors after military and civilian adult orthopaedic trauma that may influence clinical, functional, and quality of life recovery. Furthermore, it addresses additional factors that may be associated with greater biopsychosocial symptom intensity, limitations, and/or diminished health-related quality of life. However, this guideline did not evaluate effective treatment strategies for the treatment or prevention of psychosocial factors. This guideline cannot be fully extrapolated to the treatment of children or adolescents. In addition, the work group highlighted the need for additional research because studies of general traumatic injuries do not always generalize to specific orthopaedic populations.

Chronic Pain Following Fracture-Related Surgery: Posttraumatic Rather Than Postsurgical Origin Promotes Chronification-A Prospective Observational Study With 1-Year Follow-up

BACKGROUND

Chronic posttraumatic/postsurgical pain (CPSP) is common after traumatic or surgical damage. Exposure to both trauma and surgery, with the potential for repeated bone and nerve damage, may increase the risk of CPSP after fracture-related surgery. But the (long-term) incidences of CPSP and neuropathic CPSP and the ensuing burdens are unknown. Therefore, the patients were prospectively assessed within 1 year, and the patient-specific characteristics were explored.

METHODS

Between 2017 and 2018, 127 patients (age: 52.9 ± 17.1 years, male: 55.1%) with traumatic fractures needing osteosynthesis (extremities: 91.3%) were assessed posttrauma (before surgery), postsurgery at days 1 to 5, 6 weeks, 3 and 12 months. The primary outcomes are as follows: incidence at 3 and 12 months of CPSP (defined as pain intensity on a numerical rating scale [NRS: 0-10] ≥3), secondary exploration: neuropathic CPSP (NRS ≥3 and Douleur Neuropathique 4 interview [DN4i] score ≥3 [Douleur Neuropathique interview: 0-7]); burden: quality of life (QoL, the EuroQOL five dimensions questionnaire [EQ-5D-3L] descriptive system); and inter alia, the number of analgesics (trial registration: DRKS00011601).

RESULTS

The incidence of CPSP was 57.1% (52/91, n/N) at 3 and 42.7% (35/82) at 12 months postsurgery, including neuropathic CPSP 7.7% (4/52) and 17.1% (6/35), respectively. Descriptively, posttraumatic higher pain intensity at rest (difference of 0.9 ± 1.8 NRS) and the need for more frequent analgesics (by 34.3%) were associated with CPSP a year after surgery compared to those without. As soon as week 6, these patients had developed descriptively a 15% more impaired QoL, with 25% more impairment after 1 year. The patients with CPSP presented with at least 1 neuropathic symptom 12 months later in 68.6% (24/35) of cases, mainly with an early posttraumatic occurrence (without fulfilling the definition of neuropathic CPSP).

CONCLUSIONS

After early fracture-related surgery, high incidences of CPSP (43%) were prospectively observed 1 year postsurgery, up to approximately 1 in 5 patients who had neuropathic CPSP. At the same time, CPSP was accompanied with an impacted QoL and analgesic dependence, both indicating clinical relevance. Moreover, the high incidence and the early posttraumatic occurrence of more intense pain suggest that the initial fracture-related trauma, rather than the surgical trauma, may predominantly trigger CPSP at Y1 (1 year). Therefore, these exploratory results set the direction of required future research. A future clinical hypothesis might be: treat first what hurts first.

Role of psychosocial factors on the effect of physical activity on physical function in patients after lumbar spine surgery

Background

The purpose of this study was to investigate the longitudinal postoperative relationship between physical activity, psychosocial factors, and physical function in patients undergoing lumbar spine surgery.

Methods

We enrolled 248 participants undergoing surgery for a degenerative lumbar spine condition. Physical activity was measured using a triaxial accelerometer (Actigraph GT3X) at 6-weeks (6wk), 6-months (6M), 12-months (12M) and 24-months (24M) following spine surgery. Physical function (computerized adaptive test domain version of Patient-Reported Outcomes Measurement Information System) and psychosocial factors (pain self-efficacy, depression and fear of movement) were assessed at preoperative visit and 6wk, 6M, 12M and 24M after surgery. Structural equation modeling (SEM) techniques were utilized to analyze data, and results are represented as standardized regression weights (SRW). Overall SRW were computed across five imputed datasets to account for missing data. The mediation effect of each psychosocial factor on the effect of physical activity on physical function were computed [(SRW for effect of activity on psychosocial factor X SRW for effect of psychosocial factor on function) ÷ SRW for effect of activity on function]. Each SEM model was tested for model fit by assessing established fit indexes.

Results

The overall effect of steps per day on physical function (SRW ranged from 0.08 to 0.19, p<0.05) was stronger compared to the overall effect of physical function on steps per day (SRW ranged from non-existent to 0.14, p<0.01 to 0.3). The effect of steps per day on physical function and function on steps per day remained consistent after accounting for psychosocial factors in each of the mediation models. Depression and fear of movement at 6M mediated 3.4% and 5.4% of the effect of steps per day at 6wk on physical function at 12M, respectively. Pain self-efficacy was not a statistically significant mediator.

Conclusions

The findings of this study suggest that the relationship between physical activity and physical function is stronger than the relationship of function to activity. However, future research is needed to examine whether promoting physical activity during the early postoperative period may result in improvement of long-term physical function. Since depression and fear of movement had a very small mediating effect, additional work is needed to investigate other potential mediating factors such as pain catastrophizing, resilience and exercise self-efficacy.

The Prevalence and Characteristics of Phantom Limb Pain and Non-Painful Phantom Phenomena in a Nationwide Survey of 3,374 Unilateral Limb Amputees

The experience of phantom limb pain (PLP) is a common consequence of limb amputation, resulting in severe impairments of the affected person. Previous studies have shown that several factors such as age at or site of amputation are associated with the emergence and maintenance of PLP. In this cross-sectional study we assessed the presence of several phantom phenomena including PLP and other amputation-related information in a sample of 3,374 unilateral upper and lower limb amputees. Clinical and demographic variables (age at amputation, level of amputation) explained 10.6% of the variance in PLP and perceptual variables (intensity of phantom limb sensation [PLS], referred sensations, intensity of telescoping, residual limb pain [RLP] intensity) explained 16.9% of the variance. These variables were specific for PLP and not for RLP. These results suggest that distinct variables are associated with PLP (age at amputation, level of amputation, PLS intensity, referred sensations, intensity of telescoping, RLP intensity) and RLP (PLP intensity) and point at partly different mechanisms for the emergence and maintenance of PLP and RLP. PERSPECTIVE: Clinical/demographic variables as well as perceptual variables are 2 major components related to PLP and explain ∼11% and ∼17% of the variance. These results could potentially help clinicians to understand which factors may contribute to chronic phantom limb pain.

The timing of amputation of mangled lower extremities does not predict post-injury outcomes and mortality: A retrospective analysis from the ACS TQIP database

BACKGROUND

While limb salvage does not result in improved functional outcomes among patients with a mangled lower extremity, the impact of attempted limb salvage on mortality and complications is poorly understood. The objective of this study was to evaluate the relationship between attempted limb salvage and in-hospital outcomes among patients with a mangled lower extremity.

METHODS

We performed a retrospective cohort study of adults, 16 years or older, with a mangled lower extremity. Data were derived from the American College of Surgeons' Trauma Quality Improvement Program (2012-2017). We compared mortality, complications (severe sepsis, acute kidney injury [AKI], decubitus ulcers) and length of stay between patients managed with the intention of limb salvage (amputation beyond 24 hours or no amputation) and those who underwent early amputation (within 24 hours of presentation). Instrumental variable analysis was used to evaluate the relationship between management strategy and outcomes.

RESULTS

We identified 5,527 patients with a mangled lower extremity, of which 901 (16.3%) underwent early amputation. Among those managed with attempted limb salvage, 42.5% underwent amputation prior to discharge. After adjusting for patient and hospital characteristics, there was no association between initial management strategy and mortality (odds ratio, 1.20; 95% confidence interval [CI], 0.83-1.74 early amputation vs. attempted limb salvage). Early amputation was associated with lower odds of AKI (OR, 0.59; 95% CI, 0.39-0.88) and a trend toward shorter length of stay (relative risk, 0.77; 95% CI, 0.52-1.14).

CONCLUSION

Over half of patients who sustain a mangled lower extremity undergo amputation during their initial hospital course. While a limb salvage strategy is associated with an elevated risk of AKI, there is no association between attempted limb preservation and mortality. These findings suggest that in patients in which there is no clear indication for early amputation, attempts at limb salvage do not come at the cost of increased mortality.

LEVEL OF EVIDENCE

Therapeutic study, level IV.

Effect of Severe Distal Tibia, Ankle, and Mid- to Hindfoot Trauma on Meeting Physical Activity Guidelines 18 Months After Injury

OBJECTIVE

To examine the effect of severe lower extremity trauma on meeting Physical Activity Guidelines for Americans (PAGA) 18 months after injury and perform an exploratory analysis to identify demographic, clinical, and psychosocial factors associated with meeting PAGA.

DESIGN

Secondary analysis of observational cohort study.

SETTING

A total of 34 United States trauma centers PARTICIPANTS: A total of 328 adults with severe distal tibia, ankle and mid- to hindfoot injuries treated with limb reconstruction (N=328).

INTERVENTIONS

None.

MAIN OUTCOME MEASURES

The Paffenbarger Physical Activity Questionnaire was used to assess physical activity levels 18 months after injury. Meeting PAGA was defined as combined moderate- and vigorous-intensity activity ≥150 minutes per week or vigorous-intensity activity ≥75 minutes per week.

RESULTS

Fewer patients engaged in moderate- or vigorous-intensity activity after injury compared with before injury (moderate: 44% vs 66%, P<.001; vigorous: 18% vs 29%; P<.001). Patients spent 404±565 minutes per week in combined moderate- to vigorous-intensity activity before injury compared with 224±453 minutes postinjury (difference: 180min per week; 95% confidence interval [CI], 103-256). The adjusted odds of meeting PAGA were lower for patients with depression (adjusted odds ratio [AOR], 0.45; 95% CI, 0.28-0.73), women (AOR, 0.59; 95% CI, 0.35-1.00), and Black or Hispanic patients (AOR, 0.49; 95% CI, 0.28-0.85). Patients meeting PAGA prior to injury were more likely to meet PAGA after injury (odds ratio, 2.0; 95% CI, 1.20-3.31).

CONCLUSIONS

Patients spend significantly less time in moderate- to vigorous-intensity physical activity after injury. Patients with depression are less likely to meet PAGA. Although the causal relationship is unclear, results highlight the importance of screening for depression.

The impact of common chronic conditions on health-related quality of life: a general population survey in Iran using EQ-5D-5L

Background

Diseases have undeniable effects on Health-Related Quality of Life (HRQoL). Chronic diseases, in particular, limit the productive potentials and HRQoL of individuals. EQ-5D is a very popular generic instrument, which can be used to estimate HRQoL scores in any diseases. The current study investigates mean HRQoL scores in certain chronic diseases and examines the relationship between utility scores and chronic diseases in Iran.

Method

This cross-sectional study was carried out among the general adult population of Tehran. 3060 individuals were chosen by a stratified probability sampling method. The EQ-5D-5L questionnaire was applied. The utility scores were estimated using the Iranian crosswalk-based value set. The effect of chronic diseases on the HRQoL scores was derived by the Ordinary Least Squares (OLS) method. Data was analyzed using Stata version 13 software.

Results

The mean ± standard deviation utility and EQ-VAS scores were 0.85 ± 0.14 and 76.73 ± 16.55 in the participants without any chronic conditions. The scores were 0.69 ± 0.17 and 61.14 ± 20.61 in the participants with chronic conditions. The highest and lowest mean utility scores were related to thyroid disease (0.70) and Stroke (0.54), respectively. Common chronic conditions had significant negative effects on the HRQoL scores. Stroke (0.204) and cancer (0.177) caused the most reduction in the EQ-5D-5L utility scores. Lumbar disc hernia, digestive diseases, osteoarthritis, breathing problems, and anxiety/nerves cause 0.133, 0.109, 0.108, 0.087, and 0.078 reductions, respectively, in the EQ-5D-5L utility scores.

Conclusion

This study provides insight into some common chronic conditions and their effects on the HRQoL. Policymakers and planners should pay attention to the effects of chronic conditions especially high prevalence one. They should adopt effective interventions to control this issue and increase health. The results of this study can also be beneficial in economic evaluation studies.

Data-science-based subgroup analysis of persistent pain during 3 years after breast cancer surgery: A prospective cohort study

BACKGROUND

Persistent pain extending beyond 6 months after breast cancer surgery when adjuvant therapies have ended is a recognised phenomenon. The evolution of postsurgery pain is therefore of interest for future patient management in terms of possible prognoses for distinct groups of patients to enable better patient information.

OBJECTIVE(S)

An analysis aimed to identify subgroups of patients who share similar time courses of postoperative persistent pain.

DESIGN

Prospective cohort study.

SETTING

Helsinki University Hospital, Finland, between 2006 and 2010.

PATIENTS

A total of 763 women treated for breast cancer at the Helsinki University Hospital.

INTERVENTIONS

Employing a data science approach in a nonredundant reanalysis of data published previously, pain ratings acquired at 6, 12, 24 and 36 months after breast cancer surgery, were analysed for a group structure of the temporal courses of pain. Unsupervised automated evolutionary (genetic) algorithms were used for patient cluster detection in the pain ratings and for Gaussian mixture modelling of the slopes of the linear relationship between pain ratings and acquisition times.

MAIN OUTCOME MEASURES

Clusters or groups of patients sharing patterns in the time courses of pain between 6 and 36 months after breast cancer surgery.

RESULTS

Three groups of patients with distinct time courses of pain were identified as the best solutions for both clustering of the pain ratings and multimodal modelling of the slopes of their temporal trends. In two clusters/groups, pain decreased or remained stable and the two approaches suggested/identified similar subgroups representing 80/763 and 86/763 of the patients, respectively, in whom rather high pain levels tended to further increase over time.

CONCLUSION

In the majority of patients, pain after breast cancer surgery decreased rapidly and disappeared or the intensity decreased over 3 years. However, in about a tenth of patients, moderate-to-severe pain tended to increase during the 3-year follow-up.

Perceived Efficacy of Medical Cannabis in the Treatment of Co-Occurring Health-Related Quality of Life Symptoms

For persons living with chronic conditions, health-related quality of life (HRQoL) symptoms, such as pain, anxiety, depression, and insomnia, often interact and mutually reinforce one another. There is evidence that medical cannabis (MC) may be efficacious in ameliorating such symptoms and improving HRQoL. As many of these HRQoL symptoms may mutually reinforce one another, we conducted an exploratory study to investigate how MC users perceive the efficacy of MC in addressing co-occurring HRQoL symptoms. We conducted a cross-sectional online survey of persons with a state medical marijuana card in Illinois (N = 367) recruited from licensed MC dispensaries across the state. We conducted tests of ANOVA to measure how perceived MC efficacy for each HRQoL symptom varied by total number of treated symptoms reported by participants. Pain was the most frequently reported HRQoL treated by MC, followed by anxiety, insomnia, and depression. A large majority of our sample (75%) reported treating two or more HRQoL symptoms. In general, perceived efficacy of MC in relieving each HRQoL symptom category increased with the number of co-occurring symptoms also treated with MC. Perceived efficacy of MC in relieving pain, anxiety, and depression varied significantly by number of total symptoms experienced. This exploratory study contributes to our understanding of how persons living with chronic conditions perceive the efficacy of MC in treating co-occurring HRQoL symptoms. Our results suggest that co-occurring pain, anxiety, and depression may be particularly amenable to treatment with MC.

Pain, Depression, and Posttraumatic Stress Disorder Following Major Extremity Trauma Among United States Military Serving in Iraq and Afghanistan: Results From the Military Extremity Trauma and Amputation/Limb Salvage Study

OBJECTIVES

Assess the burden and co-occurrence of pain, depression, and posttraumatic stress disorder (PTSD) among service members who sustained a major limb injury, and examine whether these conditions are associated with functional outcomes.

DESIGN

A retrospective cohort study.

SETTING

Four U.S. military treatment facilities: Walter Reed Army Medical Center, National Naval Medical Center, Brooke Army Medical Center, and Naval Medical Center San Diego.

PATIENTS/PARTICIPANTS

Four hundred twenty-nine United States service members who sustained a major limb injury while serving in Afghanistan or Iraq met eligibility criteria upon review of their medical records.

INTERVENTION

Not applicable.

MAIN OUTCOME MEASUREMENTS

Outcomes assessed were: function using the short musculoskeletal functional assessment; PTSD using the PTSD Checklist and diagnostic and statistical manual criteria; pain using the chronic pain grade scale.

RESULTS

Military extremity trauma and amputation/limb salvage patients without pain, depression, or PTSD, were, on average, about one minimally clinically important difference (MCID) from age- and gender-adjusted population norms. In contrast, patients with low levels of pain and no depression or PTSD were, on average, one to 2 MCIDs from population norms. Military extremity trauma and amputation/limb salvage patients with either greater levels of pain, and who experience PTSD, depression, or both, were 4 to 6 MCIDs from population norms. Regression analyses adjusting for injury type (upper or lower limb, salvage or amputation, and unilateral or bilateral), age, time to interview, military rank, presence of a major upper limb injury, social support, presence of mild traumatic brain injury/concussion, and combat experiences showed that higher levels of pain, depression, and PTSD were associated with lower one-year functional outcomes.

CONCLUSIONS

Major limb trauma sustained in the military results in significant long-term pain and PTSD. Overall, the results are consistent with the hypothesis that pain, depression, and PTSD are associated with disability in this population.

LEVEL OF EVIDENCE

Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.

Pain management in the surgical ICU patient

PURPOSE OF REVIEW

Acute pain management in the surgical ICU is imperative. Effective acute pain management hastens a patient's return to normal function and avoid the negative sequelae of untreated acute pain. Traditionally, opioids have been the mainstay of acute pain management strategies in the surgical ICU, but alternative medications and management strategies are increasingly being utilized.

RECENT FINDINGS

Extrapolating from lessons learned from enhanced recovery after surgery protocols, surgical intensivists are increasingly utilizing multimodal pain regimens (MMPRs) in critically ill surgical patients recovering from major surgical procedures and injuries. MMPRs incorporate both oral medications from several drug classes and regional blocks when feasible. In addition, although MMPRs may include opioids as needed, they are able to achieve effective pain control while minimizing opioid exposure.

SUMMARY

Even after major elective surgery or significant injury, opioid-minimizing MMPRs can effectively treat acute pain.

The dynamic relationship between pain, depression and cognitive function in a sample of newly diagnosed arthritic adults: a cross-lagged panel model

BACKGROUND

Pain and depression are common in the population and co-morbid with each other. Both are predictive of one another and are also associated with cognitive function; people who are in greater pain and more depressed respectively perform less well on tests of cognitive function. It has been argued that pain might cause deterioration in cognitive function, whereas better cognitive function earlier in life might be a protective factor against the emergence of disease. When looking at the dynamic relationship between these in chronic diseases, studying samples that already have advanced disease progression often confounds this relationship.

METHODS

Using data from waves 1 to 3 of the English Longitudinal Study of Ageing (ELSA) (n = 516), we examined the interplay between pain, cognitive function and depression in a subsample of respondents reporting a diagnosis of arthritis at wave 2 of the ELSA using cross-lagged panel models.

RESULTS

The models showed that pain, cognitive function and depression at wave 1, prior to diagnosis, predict pain at wave 2, and that pain at wave 1 predicts depression at wave 2. Pain and depression at wave 2 predict cognitive function at wave 3.

CONCLUSIONS

The results indicate that better cognitive function might be protective against the emergence of pain prior to an arthritis diagnosis, but cognitive function is subsequently impaired by pain and depression. Furthermore, higher depression predicts lower cognitive function, but not vice versa. This is discussed in the context of the emerging importance of inflammation in depression.

Are we missing the mark? Relationships of psychosocial issues to outcomes after injury: A review of OTA annual meeting presentations

OBJECTIVES

To observe the availability of information about social, emotional, and psychological factors in abstracts presented at the Orthopaedic Trauma Association (OTA) annual meeting.

DATA SOURCE

OTA website (https://ota.org/education/meetings-and-courses/meeting-archive/).

STUDY SELECTION

All abstracts selected for paper or poster presentation at the 2016 through 2018 OTA annual meetings, as published in the final program. Studies were included if they sought to measure mental illness, substance use or abuse, pain, or other psychosocial issues. If studies utilized 1 or more patient-reported outcome measures (PROMs), they were also included.

DATA EXTRACTION

For each abstract meeting inclusion criterion, studies were assessed for interventions intended to improve outcomes in any of the listed psychosocial domains.

DATA SYNTHESIS/RESULTS

Nine hundred forty-two abstracts were evaluated over a 3-year period. Of these, 294 (31.2%) met inclusion criteria. Twenty-five abstracts (8.5% of 294) reported mental illness, with depression (n = 14), anxiety (n = 9), and posttraumatic stress disorder (n = 5) being the most common. Eighty-eight abstracts (29.9% of 294) reported substance-use of tobacco, alcohol, narcotics, and/or recreational drugs. Tobacco-use was most prevalent (n = 59), followed by opioid-use (n = 31). Ten abstracts reported substance abuse. Pain was measured in 95 abstracts, and 203 abstracts utilized PROMs. Thirty-five abstracts found that these psychosocial elements significantly impacted outcomes or complications. Many abstracts did not assess the influence of these factors on clinical outcomes (n = 99). Sixteen studies described an intervention aimed at mitigating these features.

CONCLUSIONS

This study illustrates limited attention to the impact of psychological, social, and environmental factors on outcomes after orthopaedic trauma. Substance-abuse problems and mental health concerns are not only predictors of poor clinical and PROMs of pain and quality of life after injury, but have also been implicated in subsequent recidivism. Only 3% of 942 abstracts observed mental health and 1% reported substance-abuse. Moving forward, greater understanding of psychosocial issues may enhance interventions to impact long-term outcomes.

Quantitative Sensory Testing (QST) in Drug-Naïve Patients with Parkinson's Disease

BACKGROUND

Pain is highly prevalent in patients with Parkinson's disease (PD), but underlying pathophysiological mechanisms are largely unclear. Alterations in somatosensory processing might contribute to sensory abnormalities in PD.

OBJECTIVE

This study investigated sensory processing in PD patients.

METHODS

We used the standardized "Quantitative Sensory Testing" (QST) protocol (German Research Network on Neuropathic Pain) to investigate 13 somatosensory parameters in 19 PD patients naïve to dopaminergic medication and 19 healthy controls matched for age, gender, and handedness. We tested for differences in sensory parameters between i) drug-naïve PD patients and healthy controls, ii) patients' more and less affected body side, and iii) for an association of somatosensory parameters with disease-specific factors.

RESULTS

We did not observe any significant group differences in somatosensory parameters between PD patients and healthy subjects. In PD patients, QST mean z-scores did not differ between the predominantly and the less affected body side, PD patients with and without PD-specific chronic pain or between different PD subtypes. Age, but not PD disease severity, was associated with a greater loss of function in thermal and mechanical detection thresholds.

CONCLUSIONS

Somatosensory processing, as assessed with the well-established QST protocol, was normal in drug-naïve PD patients. Thus, somatosensory abnormalities previously reported in medicated PD patients might rather be a result of dopaminergic medication, or may occur later in the course of the disease or with increasing age.

Predictors of Depression, Anxiety and Stress Indicators in a Cohort of Women with Chronic Pelvic Pain

OBJECTIVE

Establishing predictors of mental health outcomes is a crucial precursor to the development and assessment of psychological interventions for women with chronic pelvic pain (CPP). The objective of this study was to identify predictors of depression, anxiety and stress in a cohort of women with CPP.

DESIGN

Cross-sectional analytic study.

METHODS

Pre-treatment questionnaires were collected from 212 women with CPP, who had attended a private specialist pelvic pain clinic over a period of 18 months. Multivariate linear regression with backwards elimination was used to determine the best joint predictors of depression, anxiety and stress scores on the Depression, Anxiety and Stress Scale-21 item (DASS 21).

RESULTS

Of 19 potential predictor variables, seven key predictors of depression, anxiety and stress indicators were identified. Higher depression scores were associated with higher current pain severity, a history of stabbing pains, prior experience of a sexually distressing event, having experienced pain as a child, and never having been pregnant before. Higher anxiety scores were associated with higher current pain severity, a history of stabbing pains, prior experience of a sexually distressing event, younger age of menarche, and younger age. Predictors of high-stress scores were higher current pain severity, a history of stabbing pains, prior experience of a sexually distressing event, and being younger.

CONCLUSION

We have identified several important predictors of mental health in women with CPP. Using this information, psychological assessment and treatment for these women may be better tailored to client needs.

Missed targets, reaction times, and arousal are related to trait anxiety and attention to pain during an experimental vigilance task with a painful target

Although hypervigilance may play a role in some clinical pain syndromes, experimental vigilance toward painful stimuli has been studied infrequently. We evaluated vigilance toward pain by using a continuous performance task (CPT), in which subjects responded to moderately intense painful target stimuli, occurring in a train of mildly painful nontargets. We assessed nondetected targets (misses), reaction times (RTs), and psychological activation (tense arousal). During time on task in CPTs of other sensory modalities, there is an increase in misses and RTs (vigilance decrement). We hypothesized that our CPT would influence vigilance performance related to pain, anxiety, and limitation of attentional resources. The results showed a decrement in vigilance over time as misses increased, although RTs were unchanged. While mind-wandering did not influence vigilance performance, intrinsic attention to pain drove both hit RTs and number of misses. This resulted in pain-focused subjects performing worse on the CPT pain task with slower RTs and more misses per block. During the CPT, the change in stimulus salience was related to the change in pain intensity, while pain unpleasantness correlated with tense arousal. CPT performance during experimental vigilance to pain and psychological activation were related to trait anxiety, as measured by the Spielberger State-Trait Anxiety Inventory and neuroticism, as measured by the NEO five factor inventory. Trait anxiety and neuroticism may play important roles in an individual's predisposition to dwell on pain and interpret pain as threatening.NEW & NOTEWORTHY Subjects detected moderately painful target stimuli in a train of mildly painful nontarget stimuli, which resulted in vigilance performance metrics including missed targets, reaction times, and psychological activation. These performance metrics were related to intrinsic attention to pain and trait anxiety. Subjects with high trait anxiety and neuroticism scores, with a predisposition to attend to pain, had greater tense arousal and poorer vigilance performance, which may be important psychological aspects of vigilance to pain.

A 20-year study of the bidirectional relationship between anxious and depressive symptomology and pain medication usage

Aim: To investigate the 20-year relationship between anxiety, depression and pain medication use. Patients: A total of 521 individuals reporting chronic pain from the National Survey of Midlife Development in the USA (MIDUS) study. Methods: Structural equation modeling of 20-year longitudinal survey data. Results: Over 20 years, a bidirectional relationship between depression and anxiety in individuals with chronic pain was indicated. Pain medication utilization predicted later use at 10 years. Pain medication use was not strongly related to later anxiety; however, heightened anxiety was associated with later use. Conclusion: Depression and anxiety show an extensive long-term bidirectional relationship. While there was little indication of a relationship between pain medication use and later negative mood, anxiety was associated with subsequent pain medication use.

Pain-related psychological issues in hand therapy

STUDY DESIGN

Literature review.

INTRODUCTION

Pain is a subjective experience that results from the modulation of nociception conveyed to the brain via the nervous system. Perception of pain takes place when potential or actual noxious stimuli are appraised as threats of injury. This appraisal is influenced by one's cognitions and emotions based on her/his pain-related experiences, which are processed in the forebrain and limbic areas of the brain. Unarguably, patients' psychological factors such as cognitions (eg, pain catastrophizing), emotions (eg, depression), and pain-related behaviors (eg, avoidance) can influence perceived pain intensity, disability, and treatment outcomes. Therefore, hand therapists should address the patient pain experience using a biopsychosocial approach. However, in hand therapy, a biomedical perspective predominates in pain management by focusing solely on tissue healing.

PURPOSE OF THE STUDY

This review aims to raise awareness among hand therapists of the impact of pain-related psychological factors.

METHODS AND RESULTS

This literature review allowed to describe (1) how the neurophysiological mechanisms of pain can be influenced by various psychological factors, (2) several evidence-based interventions that can be integrated into hand therapy to address these psychological issues, and (3) some approaches of psychotherapy for patients with maladaptive pain experiences.

DISCUSSION AND CONCLUSION

Restoration of sensory and motor functions as well as alleviating pain is at the core of hand therapy. Numerous psychological factors including patients' beliefs, cognitions, and emotions alter their pain experience and may impact on their outcomes. Decoding the biopsychosocial components of the patients' pain is thus essential for hand therapists.

Early Effects of the Trauma Collaborative Care Intervention: Results From a Prospective Multicenter Cluster Clinical Trial

OBJECTIVES

To evaluate the impact of the Trauma Collaborative Care (TCC) program's early intervention components on 6-week outcomes. TCC was developed to improve psychosocial sequelae of orthopaedic trauma and includes the Trauma Survivors Network and additional collaborative care services.

DESIGN

Prospective, multicenter, cluster clinical trial.

SETTING

Level I Trauma Centers.

PATIENTS

Individuals with high-energy orthopaedic injuries requiring surgery and hospital admission: 413 patients at 6 trauma centers implementing the TCC program and 374 patients at 6 trauma centers receiving usual care.

INTERVENTION

TCC early intervention: patient education, peer visits, and coaching calls.

MAIN OUTCOME MEASUREMENTS

Pain rating scale, Patient Health Questionnaire-9 depression, Post-Traumatic Stress Disorder Checklist, and self-efficacy for return to work and managing finances. For each outcome, a hybrid Bayesian statistical procedure, accounting for clustering within sites and differences in baseline characteristics between sites, was used to estimate the intention-to-treat (ITT) effect and the effect under full receipt of early intervention components.

RESULTS

Sites varied substantially in utilization of intervention components. The posterior estimates of the ITT (full receipt) effect favor TCC for 4 (5) of the 5 endpoints. The posterior probabilities of a favorable (ITT; full receipt) TCC effect were as follows: depression (89%-93%), pain (84%-74%), post-traumatic stress disorder (68%-68%), self-efficacy for return to work (74%-76%), and self-efficacy for managing finances (47%-61%).

CONCLUSIONS

Results suggest TCC may have a small positive effect on early outcomes, but use of the services was highly variable among sites.

LEVEL OF EVIDENCE

Mental health outcomes after major trauma in Ontario: a population-based analysis

BACKGROUND

Major injury continues to be a common source of morbidity and mortality; improving the functional recovery of survivors of major trauma requires a better understanding of the mental health outcomes that may occur in this population. We assessed the association between major trauma and the development of a new mental health diagnosis or death by suicide.

METHODS

We completed a population-based, self-controlled, longitudinal cohort analysis using linked administrative data on patients treated for major trauma in Ontario between 2005 and 2010. All survivors were included and composite rates of mental health diagnoses during inpatient admissions were compared between the 5 years after injury and the 5 years before injury, using Poisson regression with generalized estimating equations. The incidence of suicide was calculated for the 5 years after injury. Risk factors for suicide were calculated using Cox proportional hazard regression analyses.

RESULTS

The analysis included 19 338 patients, predominantly men (70.7%) from urban areas (82.6%), with unintentional (89%), blunt injuries (93.4%). Overall, trauma was associated with a 40% increase in the postinjury rate of mental health diagnoses (incidence rate ratio [IRR] 1.4, 95% [confidence interval] CI 1.1 to 1.8). The suicide rate was 70 per 100 000 patients per year, substantially higher than the population average. Risk factors for completing suicide were prior inpatient diagnosis of mood disorder (hazard ratio [HR] 4.3, 95% CI 2.1 to 8.8) and self-inflicted injury (HR 7.8, 95% CI 3.9 to 15.4).

INTERPRETATION

Survivors of major trauma are at a heightened risk of developing mental health conditions or death by suicide in the years after their injury. Patients with pre-existing mental health disorders or who are recovering from a self-inflicted injury are at particularly high risk.

Prospective cohort study examining the use of regional anesthesia for early pain management after combat-related extremity injury

BACKGROUND

No studies have examined the long-term benefits of regional anesthesia (RA) for pain management after combat-related injury. The objective of this prospective cohort study was to examine the relationship between RA administration and patient-reported pain-related outcomes among Operation Enduring Freedom (OEF) and Operation Iraqi Freedom (OIF) service members sustaining a combat-related extremity injury.

METHODS

Between 2007 and 2013, n=358 American military personnel injured in OEF/OIF were enrolled at two military treatment facilities. Individuals were followed for up to 2 years after injury. Cohorts were defined based on whether participants were administered RA within 7 days after sustaining a combat-related injury, or not. Linear mixed effects models examined the association between RA and average pain intensity. Secondary outcomes included pain relief, pain interference, neuropathic pain symptoms, treatment outcomes related to pain management, and mental health symptoms.

RESULTS

Receiving early RA was associated with improved average pain over the first 6 months after injury (β=-0.57; p=0.012) adjusting for injury severity and length of stay at the primary treatment facility. This difference was observed up to 24 months after injury (β=-0.36; p=0.046). Individuals receiving early RA reported greater pain relief, improved neuropathic pain intensity, and higher satisfaction with pain outcomes; however, by 24 months, mean scores did not significantly differ between cohorts.

CONCLUSION

Findings indicate that when administered soon after traumatic injury, RA is a valuable pain management intervention. Future longitudinal studies investigating the timely delivery of RA for optimal pain management in civilian trauma settings are needed.

Do Health-Related Quality of Life and Pain-Coping Strategies Explain the Relationship between Older Women Participants in a Pilates-Aerobic Program and Bodily Pain? A Multiple Mediation Model

This study (1) analyzes the differences between non-participating and participating older women in terms of clinical characteristics, pain coping strategies, health-related quality of life and physical activity (PA); (2) studies the associations between non-participants and participants, clinical characteristics, pain coping strategies, HRQoL and bodily pain and PA; and (3) determines whether catastrophizing, physical role, behavioural coping, social functioning and emotional role are significant mediators in the link between participating in a Pilates-aerobic program (or not) and bodily pain. The sample comprised 340 older women over 60 years old. Participants of the present cross-sectional study completed measures of clinical characteristics: HRQoL using the SF-36 Health Survey, pain-coping strategies using the Vanderbilt Pain Management Inventory (VPMI) and PA using the International Physical Activity Questionnaire (IPAQ). Significant differences between non-participants and participants, were found in clinical characteristics, pain-coping strategies (both, p < 0.05), HRQoL (p < 0.01), and PA (p < 0.001). Moreover, catastrophizing support mediated the link between non-participants and participants and bodily pain by 95.9% of the total effect; 42.9% was mediated by PA and 39.6% was mediated by behavioural coping. These results contribute to a better understanding of the link between PA and bodily pain.

Association of pain after trauma with long-term functional and mental health outcomes

BACKGROUND

Chronic pain after trauma is associated with serious clinical, social, and economic burden. Due to limitations in trauma registry data and previous studies, the current prevalence of chronic pain after trauma is unknown, and little is known about the association of pain with other long-term outcomes. We sought to describe the long-term burden of self-reported pain after injury and to determine its association with positive screen for posttraumatic stress disorder (PTSD), functional status, and return to work.

METHODS

Trauma survivors with moderate or severe injuries and one completed follow-up interview at either 6 months or 12 months after injury were identified from the Functional Outcomes and Recovery after Trauma Emergencies project. Multivariable logistic regression models clustered by facility and adjusting for confounders were used to obtain the odds of positive PTSD screening, not returning to work, and functional limitation at 6 months and 12 months after injury, in trauma patients who reported to have pain on a daily basis compared to those who did not.

RESULTS

We completed interviews on 650 patients (43% of eligible patients). Half of patients (50%) reported experiencing pain daily, and 23% reported taking pain medications daily between 6 months and 12 months after injury. Compared to patients without pain, patients with pain were more likely to screen positive for PTSD (odds ratio [OR], 5.12; 95% confidence interval [CI], 2.97-8.85), have functional limitations for at least one daily activity (OR, 2.42; 95% CI, 1.38-4.26]), and not return to work (OR, 1.86; 95% CI, 1.02-3.39).

CONCLUSIONS

There is a significant amount of self-reported chronic pain after trauma, which is in turn associated with positive screen for PTSD, functional limitations, and delayed return to work. New metrics for measuring successful care of the trauma patient are needed that span beyond mortality, and it is important we shift our focus beyond the trauma center and toward improving the long-term morbidity of trauma survivors.

Conditioned pain modulation in drug-naïve patients with de novo Parkinson's disease

Background

Pain is highly prevalent in patients with Parkinson’s disease (PD), but underlying pathophysiological mechanisms are largely unclear. In many chronic pain syndromes deficits in endogenous pain inhibition have been detected that can be assessed using conditioned pain modulation paradigms. Previous studies employing this approach in medicated PD patients did not find abnormal pain inhibition. However, these results might have been confounded by residual dopaminergic medication.

Methods

An established conditioned pain modulation paradigm was used in 17 drug-naïve de novo PD patients and 17 healthy age and gender-matched controls. We tested i) whether conditioned pain modulation responses differed between the patient and control group and ii) whether pain inhibition differed between PD subtypes.

Results

PD patients and healthy controls did not differ in their conditioned pain modulation responses. Furthermore, there were no significant differences in CPM responses depending on the PD subtype. However, at a descriptive level, tremor-dominant patients showed a tendency for better descending pain inhibition compared to akinetic-rigid and mixed type patients.

Conclusions

In this first study investigating conditioned pain modulation in de novo PD patients, we found no additional impairment in descending pain modulation besides the known age-related decline. Our findings indicate that mechanisms other than an impaired descending inhibition contribute to high pain prevalence rates in PD and suggest that mechanisms underlying pain may differ between PD subtypes.

Patient Outcomes in Orthopaedic Trauma: How to Evaluate if Your Treatment Is Really Working?

Outcomes are critical to gauge the success of our treatments and, in particular, surgical interventions in orthopaedic trauma. Patient-reported outcomes have evolved to become the primary measurement of success in surgery. This article reviews the concepts relevant to understanding these outcomes including general health outcomes, extremity- and disease-specific outcomes, minimum clinically important difference, economic analysis of treatment cost/benefit, and the impact of psychosocial factors on outcomes. An understanding of these concepts is important to allow for effective interpretation and critical analysis of the literature as well as to facilitate the practice of evidence-based medicine.

Mental illness is associated with more pain and worse functional outcomes after ankle fracture

Objectives

To assess clinical and functional outcomes after ankle fracture in patients with preexisting mental illness.

Design

Retrospective study.

Setting

Level 1 trauma center.

Patients/Participants

One thousand three hundred seventy-eight adult patients treated for ankle fractures; 228 (17%) had preexisting mental illness.

Intervention

Open reduction internal fixation.

Main outcome measure

Rates of complications and reoperations. Functional outcomes were assessed via Foot Function Index (n = 530) and Short Musculoskeletal Function Assessment (n = 530).

Results

Depression was the most common mental illness (63%), followed by anxiety (23%). Mental illness was associated with older age, female sex, and preexisting medical comorbidities, including diabetes and obesity. Mental illness was not associated with specific fracture patterns or open injury. Complications occurred no more often in patients with mental illness, but secondary operations (13% vs 7%) were more likely, particularly implant removals (8% vs 4%), both P < .05. Functional outcomes were worse in mentally ill patients as measured by the Foot Function Index (39 vs 30, P = .006) and Short Musculoskeletal Function Assessment Mobility: 45 vs 35, Bothersome: 35 vs 26 and Dysfunction: 35 vs 26, all P < .01.

Conclusion

Secondary operations were nearly 50% more frequent in patients with mental illness, and functional outcome scores were significantly worse, suggesting that mental illness, unrelated to injury and treatment parameters, has major influence on outcomes. In the future, strategies to identify and treat mental illness prior to and after treatment could improve functional outcomes following ankle fracture.

Clinical Practice Guidelines for Pain Management in Acute Musculoskeletal Injury

PURPOSE

We aimed to produce comprehensive guidelines and recommendations that can be utilized by orthopaedic practices as well as other specialties to improve the management of acute pain following musculoskeletal injury.

METHODS

A panel of 15 members with expertise in orthopaedic trauma, pain management, or both was convened to review the literature and develop recommendations on acute musculoskeletal pain management. The methods described by the Grading of Recommendations Assessment, Development, and Evaluation Working Group were applied to each recommendation. The guideline was submitted to the Orthopaedic Trauma Association (OTA) for review and was approved on October 16, 2018.

RESULTS

We present evidence-based best practice recommendations and pain medication recommendations with the hope that they can be utilized by orthopaedic practices as well as other specialties to improve the management of acute pain following musculoskeletal injury. Recommendations are presented regarding pain management, cognitive strategies, physical strategies, strategies for patients on long term opioids at presentation, and system implementation strategies. We recommend the use of multimodal analgesia, prescribing the lowest effective immediate-release opioid for the shortest period possible, and considering regional anesthesia. We also recommend connecting patients to psychosocial interventions as indicated and considering anxiety reduction strategies such as aromatherapy. Finally, we also recommend physical strategies including ice, elevation, and transcutaneous electrical stimulation. Prescribing for patients on long term opioids at presentation should be limited to one prescriber. Both pain and sedation should be assessed regularly for inpatients with short, validated tools. Finally, the group supports querying the relevant regional and state prescription drug monitoring program, development of clinical decision support, opioid education efforts for prescribers and patients, and implementing a department or organization pain medication prescribing strategy or policy.

CONCLUSIONS

Balancing comfort and patient safety following acute musculoskeletal injury is possible when utilizing a true multimodal approach including cognitive, physical, and pharmaceutical strategies. In this guideline, we attempt to provide practical, evidence-based guidance for clinicians in both the operative and non-operative settings to address acute pain from musculoskeletal injury. We also organized and graded the evidence to both support recommendations and identify gap areas for future research.

Association Between 6-Week Postdischarge Risk Classification and 12-Month Outcomes After Orthopedic Trauma

Importance

Numerous studies have demonstrated that long-term outcomes after orthopedic trauma are associated with psychosocial and behavioral health factors evident early in the patient's recovery. Little is known about how to identify clinically actionable subgroups within this population.

Objectives

To examine whether risk and protective factors measured at 6 weeks after injury could classify individuals into risk clusters and evaluate whether these clusters explain variations in 12-month outcomes.

Design, Setting, and Participants

A prospective observational study was conducted between July 16, 2013, and January 15, 2016, among 352 patients with severe orthopedic injuries at 6 US level I trauma centers. Statistical analysis was conducted from October 9, 2017, to July 13, 2018.

Main Outcomes and Measures

At 6 weeks after discharge, patients completed standardized measures for 5 risk factors (pain intensity, depression, posttraumatic stress disorder, alcohol abuse, and tobacco use) and 4 protective factors (resilience, social support, self-efficacy for return to usual activity, and self-efficacy for managing the financial demands of recovery). Latent class analysis was used to classify participants into clusters, which were evaluated against measures of function, depression, posttraumatic stress disorder, and self-rated health collected at 12 months.

Results

Among the 352 patients (121 women and 231 men; mean [SD] age, 37.6 [12.5] years), latent class analysis identified 6 distinct patient clusters as the optimal solution. For clinical use, these clusters can be collapsed into 4 groups, sorted from low risk and high protection (best) to high risk and low protection (worst). All outcomes worsened across the 4 clinical groupings. Bayesian analysis shows that the mean Short Musculoskeletal Function Assessment dysfunction scores at 12 months differed by 7.8 points (95% CI, 3.0-12.6) between the best and second groups, by 10.3 points (95% CI, 1.6-20.2) between the second and third groups, and by 18.4 points (95% CI, 7.7-28.0) between the third and worst groups.

Conclusions and Relevance

This study demonstrates that during early recovery, patients with orthopedic trauma can be classified into risk and protective clusters that account for a substantial amount of the variance in 12-month functional and health outcomes. Early screening and classification may allow a personalized approach to postsurgical care that conserves resources and targets appropriate levels of care to more patients.

Association Between Sleep Quality, Mood Status, and Ocular Surface Characteristics in Patients With Dry Eye Disease

PURPOSE

To evaluate sleep and mood status in patients with dry eye disease (DED) and analyze the association between sleep quality, mood status, and ocular surface characteristics.

METHODS

Consecutive patients with DED (N = 106) and age- and sex-matched healthy controls (N = 50) were enrolled. Tear fluid break up time (TBUT), corneal fluorescein staining, and Schirmer I tests were performed in the order listed here to evaluate dry eye. A visual analog scale was used to assess dry eye symptom severity. All subjects also completed the Pittsburgh Sleep Quality Index (PSQI, scores ≥5.5 indicated poor sleep), Patient Health Questionnaire (scores ≥5 indicated depression), and General Anxiety Disorder Scale (scores ≥5 indicated anxiety).

RESULTS

Mean Pittsburgh Sleep Quality Index global score was significantly higher in patients with DED than that in controls (7.8 ± 3.9 vs. 5.4 ± 3.0, respectively; P < 0.001). Patients with DED demonstrated higher respective depression and anxiety scores compared with controls (P < 0.001 and 0.013, respectively). In the DED group, patients with poor sleep quality had more severe DED indicated by shorter TBUT and lower Schirmer I findings. A significant correlation was found between sleep quality and mood status in patients with DED. Regression analysis revealed that shorter TBUT and lower Schirmer I test results were associated with poorer sleep quality (adjusted p = 0.011 and 0.037, respectively). More severe symptoms of dry eye were significantly associated with a higher level of anxiety in patients with DED (adjusted p = 0.011).

CONCLUSIONS

Sleep quality may play an important role in the development of DED by influencing tear secretion and tear film stability and/or by indirectly aggravating anxiety and depression, leading to higher self-reported symptom scores. It is also possible that DED contributes to reduced sleep quality, as well as the development of anxiety and depression.

The effect of orthodontic separator and short-term fixed orthodontic appliance on inflammatory mediators and somatosensory function

BACKGROUND

Although inflammation can alter cytokines release and nerve function, it is not yet fully established if orthodontic-induced inflammation can cause significant extraoral trigeminal somatosensory alterations and release of inflammatory chemical mediators.

OBJECTIVE

The primary aim of this study was to investigate the impact of orthodontic separator and short-term fixed orthodontic appliance on the extraoral trigeminal somatosensory function and concentrations of cytokines in the gingival crevicular fluid (GCF).

METHODS

Twenty-two female patients were evaluated as follow: baseline, 24 hour-after elastomeric separator (-aES), 24 hour- and 1 month-after bonding brackets (-aBB) at both arches. The outcome variables were as follows: self-reported pain (Visual Analog Scale), QSTs (current perception threshold-CPT, cold detection threshold-CDT, warm detection threshold-WDT, mechanical detection threshold-MDT, mechanical suprathreshold-MST and wind-up ratio-WUR. All QSTs were performed at infra-orbital and mental nerve entry zone at patient`s dominant side. In addition, GCF samples in order to assess cytokines profile (IL-1β,IL-8,IL-6 and TNF-α) were collected. ANOVA and Tukey's post hoc analyses were performed (a = 5%).

RESULTS

Patients reported higher pain intensity 24 hour-aBB compared to baseline and 24 hour-aES (P < 0.050). Patients were less sensitive to pin-prick pain (MST) at 24 hour-aBB and 1 month-aBB compared to baseline (P < 0.006). Significant increases in IL-6 levels were observed 24 hour-aBB (P < 0.001). Multiple comparison analysis showed significant increase in IL-1β levels (P < 0.001) and TNF-α (P < 0.001) 1 month-aBB compared to baseline.

CONCLUSION

Elastomeric separators only induced mild pain and were not able to significantly increase proinflammatory cytokines level in the GCF. In addition, orthodontic fixed appliance may induce only minor somatosensory changes at extraoral trigeminal locations.

A questionnaire-based study of sleep-wake patterns and sleep quality in a TMJ and orofacial pain clinic

OBJECTIVE

To determine the relationships among sleep quality, perceived pain, and psychological distress among patients with TMJ and orofacial pain.

METHODS

The authors examined 3276 patients with temporomandibular disorder (TMD) who visited the Orofacial Pain Clinic at Yonsei University College of Dentistry. The authors conducted a survey using the sleep-quality questionnaire and classified TMD patients into two groups based on Diagnostic Criteria for TMD. For statistical analysis, the authors calculated the correlations between pain intensity as measured using a numeric rating scale (NRS) and various factors.

RESULTS

The statistical analysis revealed correlations between pain intensity on the NRS and some of the factors in the sleep questionnaire. The pain intensity increased with age and for lower sleep efficiency (both p < 0.05).

CONCLUSION

These results imply that clinicians treating patients with orofacial pain should examine their sleep-wake patterns and sleep quality.
