Pain assessment conventionally has been viewed hierarchically with self-report as its "gold-standard." Recent attempts to improve pain management have focused on the importance of assessment, for example, the initiative to include pain as the "fifth vital sign." We question the focus in the conceptualization of pain assessment upon a "vital sign," not in terms of the importance of assessment, but in terms of the application of self-report as a mechanistic index akin to a biologic measure such as heart rate and blood pressure. We synthesize current inclusive models of pain and pain assessment and propose a more comprehensive conceptualization of pain assessment as a transaction based on an organismic interplay between the patient and clinician.

Previous research has demonstrated an association between lifetime exposure to adverse events and chronic back pain (CBP), but the nature of this relationship has not been fully specified. Adversity exposure typically predicts undesirable outcomes, suggesting that lack of all adversity is optimal. However, we hypothesized that among individuals faced with CBP, a history of a low level of lifetime adversity would yield protective effects, manifested as lower impairment and healthcare utilization. Adult members of a national panel (N=396) endorsed a history of CBP when reporting their physical health status in an online survey; they further reported their functional impairment and healthcare utilization. Respondents had previously completed a survey of lifetime exposure to adverse events. Significant U-shaped quadratic relationships emerged between adversity and self-rated functional impairment (p<0.001), disabled employment status (p<0.001), frequency of physician/clinic visits for CBP (p<0.01), prescription (but not over-the-counter) analgesic use (p<0.01), and comorbid depression treatment seeking (p<0.01). Specifically, people with some lifetime adversity reported less impairment and healthcare utilization than people who had experienced either no adversity or a high level of adversity. Additional analyses failed to support alternative explanations of the findings. Implications for understanding and promoting resilience in the context of CBP are discussed.

e analyzed a statewide survey of individuals with chronic back and neck pain to determine whether prevalence and care use varied by patient race or ethnicity. We conducted a telephone survey of a random sample of 5,357 North Carolina households in 2006. Adults with chronic (>3 months duration or >24 episodes of pain per year), impairing back or neck pain were identified and were asked to complete a survey about their health and care utilization. 837 respondents (620 white, 183 black, 34 Latino) reported chronic back or neck pain. Whites and blacks had similar rates of chronic back pain. Back pain prevalence was lower in Latinos (10.4% [9.3-11.6] vs 6.3% [3.8-8.8]), likely due to their younger age; and the prevalence of chronic, disabling neck pain was lower in blacks (2.5% [1.9-3.1] vs 1.1% [.04-1.9]). Blacks had higher pain scores in the previous 3 months (5.2 vs 5.9 P < .05), and higher Roland disability scores (0-23 point scale): 14.2 vs 16.8, P < .05. Care seeking was similar among races (83% white, 85% black, 72% Latino). Use of opioids was also similar between races, at 49% for whites, 52% for blacks, and trended lower at 35% for Latinos. We found few racial/ethnic differences in care seeking, treatment use, and use of narcotics for the treatment of chronic back and neck pain.

PERSPECTIVE: This article presents new, population-based data on the issue of racial and ethnic disparities in neck- and back-pain prevalence and care. Few disparities were found; care quality issues may affect all ethnic groups similarly. Previous findings of disparities in chronic-pain management may be decreasing, or may perhaps be site specific.

BACKGROUND CONTEXT: Chronic back pain is a condition characterized by high rates of disability, health-care service use, and costs.

PURPOSE: The purpose of this study was to identify factors associated with patients' satisfaction with their last health-care provider visit for chronic low back pain (LBP).

STUDY DESIGN/SETTING: A cross-sectional, state-level, telephone survey was administered to patients with chronic LBP.

PATIENT SAMPLE: The sample consisted of 624 individuals with chronic LBP who reported seeing a health-care provider in the previous year.

OUTCOME MEASURES: Dependent variables included satisfaction with last visit for LBP and intent to seek care from additional providers. Independent variables included the Roland-Morris Disability Questionnaire, 3-month pain ratings using a 0 to 10 Likert scale, the Medical Outcomes Survey Short Form 12, and self-reported health service utilization (provider type, number of visits to health-care providers, medication use during the previous month, and treatments and diagnostic tests during the previous year).

METHODS: Bivariate and multivariate analyses were used to explore how demographic, insurance-related, and health-related characteristics were associated with patient satisfaction.

RESULTS: Participants who were not satisfied with one or more aspects of their last clinic visit were younger (51.0 vs. 54.21 years), reported higher 3-month pain ratings (7.23 vs. 6.53), and were more commonly Hispanic (53.2% vs. 46.8% for other ethnicities) and uninsured (43.1% vs. 29.3% for other insurance groups). Those who intended to seek care from additional providers were younger (50.05 vs. 55.49 years), had higher 3-month pain ratings (7.20 vs. 6.46), had lower Short Form 12 mental health component scores (44.75 vs. 49.55) and physical component scores (30.07 vs. 31.55), and were more commonly black (54.6% vs. 45.4% for other racial groups) and uninsured (56.9% vs. 43.1% for other insurance groups). Narcotic use was associated with satisfaction (odds ratio=2.12, p=.01), whereas lack of insurance was associated with respondents' intent to seek care from additional providers (odds ratio=2.97, p<.01).

CONCLUSIONS: Factors other than disability were associated with satisfaction with chronic LBP visits. Understanding the role of medication in satisfaction and its implications for the health behaviors of this highly disabled population may be particularly important.

OBJECTIVE: To describe exercise prescription in routine clinical practice for individuals with chronic back or neck pain because, although current practice guidelines promote exercise for chronic back and neck pain, little is known about exercise prescription in routine care.

METHODS: We conducted a computer-assisted telephone survey of a representative sample of individuals (n = 684) with chronic back or neck pain who saw a physician, chiropractor, and/or physical therapist (PT) in the past 12 months. Individuals were asked about whether they were prescribed exercise, the amount of supervision received, and the type, duration, and frequency of the prescribed exercise. Descriptive and multivariable regression analyses were conducted.

RESULTS: Of the 684 subjects, 48% were prescribed exercise. Of those prescribed exercise, 46% received the prescription from a PT, 29% from a physician, 21% from a chiropractor, and 4% from other. In multivariable analyses, seeing a PT or a chiropractor were the strongest predictors of exercise prescription. The likelihood of exercise prescription was increased in women, those with higher education, and those receiving worker's compensation. PTs were more likely to provide supervision and prescribe strengthening exercises compared with physicians and chiropractors, and were more likely to prescribe stretching exercises compared with physicians.

CONCLUSION: Our findings suggest that exercise is being underutilized as a treatment for chronic back and neck pain and, to some extent, that the amount of supervision and types of exercises prescribed do not follow current practice guidelines. Exercise prescription provided by PTs appears to be most in line with current guidelines.

Background National or state-level estimates on trends in the prevalence of chronic low back pain (LBP) are lacking. The objective of this study was to determine whether the prevalence of chronic LBP and the demographic, health-related, and health care–seeking characteristics of individuals with the condition have changed over the last 14 years.

Methods A cross-sectional, telephone survey of a representative sample of North Carolina households was conducted in 1992 and repeated in 2006. A total of 4437 households were contacted in 1992 and 5357 households in 2006 to identify noninstitutionalized adults 21 years or older with chronic (>3 months), impairing LBP or neck pain that limits daily activities. These individuals were interviewed in more detail about their health and health care seeking.

Results The prevalence of chronic, impairing LBP rose significantly over the 14-year interval, from 3.9% (95% confidence interval [CI], 3.4%-4.4%) in 1992 to 10.2% (95% CI, 9.3%-11.0%) in 2006. Increases were seen for all adult age strata, in men and women, and in white and black races. Symptom severity and general health were similar for both years. The proportion of individuals who sought care from a health care provider in the past year increased from 73.1% (95% CI, 65.2%-79.8%) to 84.0% (95% CI, 80.8%-86.8%), while the mean number of visits to all health care providers were similar (19.5 [1992] vs 19.4 [2006]).

Conclusions The prevalence of chronic, impairing LBP has risen significantly in North Carolina, with continuing high levels of disability and health care use. A substantial portion of the rise in LBP care costs over the past 2 decades may be related to this rising prevalence.

The primal face of pain (PFP) is postulated to be a common and universal facial expression to pain, hardwired and present at birth. We evaluated its presence by applying a computer-based methodology consisting of "point-pair" comparisons captured from video to measure facial movement in the pain expression by way of change across two images: one image before and one image after a painful stimulus (heel-stick). Similarity of facial expression was analyzed in a sample of 57 neonates representing both sexes and 3 ethnic backgrounds (African American, Caucasian and Hispanic/Latino) while controlling for these extraneous and potentially modulating factors: feeding type (bottle, breast, or both), behavioral state (awake or asleep), and use of epidural and/or other perinatal anesthesia. The PFP is consistent with previous reports of expression of pain in neonates and is characterized by opening of the mouth, drawing in of the brows, and closing of the eyes. Although facial expression was not identical across or among groups, our analyses showed no particular clustering or unique display by sex, or ethnicity. The clinical significance of this commonality of pain display, and of the origin of its potential individual variation begs further evaluation.

Facial Expression and Pain Assessment in the Pediatric Patient: The Primal Face of Pain

PURPOSE: This paper aims to explore the role of facial expression in pediatric pain assessment. A comparison of tools employing facial expression methodology is presented. The concept of the primal face of pain (PFP) is introduced. CONCLUSION: The PFP offers an explanation to the utility and deficiency of facial pain scales and facial expression in pain assessment. PRACTICE IMPLICATIONS: The complexities of pain measurement should preclude the clinical application of untested instruments. For reported tools, a careful evaluation of the psychometric properties and the clinical context must precede application. The concept of the PFP warns against the application of facial pain scales as proxy measures in their intended population. Reliance on facial expression to assess pain in the school-age child is imprecise.

Is There a Primal Face of Pain? A Methodology Answer.

Pain assessment is of high priority in the clinical setting. Facial Pain Scales (FPSs) are pain assessment tools generally used with school-aged children. The implicit theoretical bases for the success of FPSs have seldom been explored. Explanations why and how FPSs work (or do not work) have not been addressed. We support the existence of a universal pain expression--the Primal Face of Pain (PFP), which is present at birth, evolved in nature, and modulated through sociocultural factors. We propose it to be key in understanding the applicability of FPSs. We present here the design of a computer-assisted descriptive study that will observe, quantify and model the PFP as present in newborns. Measurement of the PFP will lead to exploration of the theoretical consequences of its existence, particularly as related to pediatric pain assessment and the valid use of FPSs. Further, this work can lay a foundation for the development of a new generation of FPSs.
