Psychologic reasons for patients preferring minimally invasive total hip arthroplasty.

Success of an orthopaedic operation depends on patients achieving their primary goal(s) and having satisfaction with the outcome. The enthusiasm of patients for minimally invasive total hip arthroplasty seems related to satisfaction with the operation. We hypothesized patients' attitude toward a small incision would increase their confidence and satisfaction with the operation but the importance of the incision would dissipate after patients realized their goals of pain relief and functional recovery. One hundred sixty-five patients responded to a 14-question patient-perception questionnaire preoperatively and 6 weeks postoperatively and a followup survey at 6 months to 1 year postoperatively. One hundred nine patients had small incisions (mean, 9.6 cm) and 56 had long incisions (mean, 17.9 cm). Preoperatively patients expected small-incision surgery would positively influence their primary goals and satisfaction; at 6 weeks postoperative they believed more strongly that this was true. By 6 months to 1 year, the importance of the incision diminished because 100% of patients met their primary goals. Forty percent of patients with a long incision were not satisfied and the reasons given were related to the process of reincorporating their injured hip into their whole-body image. We confirmed our first hypothesis that a small incision influences a patient's satisfaction postoperatively; we could not confirm our second hypothesis that incision length did not matter after attaining primary goals.

A cost-utility analysis of chronic spinal pain treatment outcomes: converting SF-36 data into quality-adjusted life years.

OBJECTIVES: The present retrospective case review study sought to analyze the cost-utility, expressed in cost/quality-adjusted life years (QALY), of current chronic spinal pain treatments. In addition, it expands upon previously published data evaluating the efficacy of interdisciplinary pain management in relation to medication management. METHODS: A recently developed algorithm was used to calculate QALYs using SF-36, v. 1 responses for 121 patients receiving treatment for chronic spinal pain at a pain rehabilitation center. Treatment groups evaluated were: (1) interdisciplinary program completers who received medication management and supplementary anesthetic procedures; (2) interdisciplinary program completers receiving medication management but not anesthetic procedures; (3) patients receiving medication management alone; and (4) patients receiving medication management with supplemental anesthetic procedures. Assessments were conducted at pretreatment and 6 months after the initiation of treatment. RESULTS: One-way analyses of covariance indicated that patients who participated in an interdisciplinary pain management program, which included medication management, psychotherapy, group education, and physical therapy, reported significantly less impairment in daily activities of living, less subjective experience of pain, and a higher quality of life and more preferred health state at the completion of their treatment phase, relative to patients receiving medication with or without anesthetic procedures. In addition, improvements in all outcome measures between pretreatment and posttreatment were significantly greater for those patients completing the interdisciplinary component of treatment. Cost-utility analyses revealed that the interdisciplinary treatment alone group was cost-saving, relative to the medication and procedures alternative, suggesting the former modality was both less costly and more effective than the latter. DISCUSSION: Average cost-utility ratios for both interdisciplinary treatment groups, ranging from 57,627 dollars /QALY to 75,885 dollars /QALY, were within established cost-effective parameters (20,000 dollars to 100,000 dollars /QALY, generally considered a good value), whereas cost-utility ratios for the standard care treatment groups were not interpretable because of a decrease in QALYs from pretreatment to posttreatment.

Bioterrorism, stress, and pain: the importance of an anticipatory community preparedness intervention.

This article reviews the accumulating scientific evidence demonstrating the negative impact caused by a cataclysmic event, such as bioterrorism, on the mental health of a community. Moreover, the potential mental health problems created by the continuing threat of possible future events are discussed. This close link among disaster events, stress, pain, and psychopathology is presented from a biopsychosocial perspective. Although there are now efforts being systematically developed to prepare for possible future biological or chemical terrorism events, there is currently also a critical need for early mental health intervention in response to future attacks to decrease psychiatric sequelae, especially workforce illness and morbidity. In this article, examples of such emergency bioterrorism preparedness, incorporating a major focus on mental health issues, are reviewed. Although these are now recognized needs, there is still not a concerted effort to prepare the population for the mental health sequelae that would be produced by such events.

Interdisciplinary treatment of failed back surgery syndrome (FBSS): a comparison of FBSS and non-FBSS patients.

Many patients enrolled in chronic pain centers suffer from failed back surgery syndrome (FBSS). However, there has been a paucity of research concerning how these patients differ from other chronic pain patients, and how to most effectively address their complex problems within an interdisciplinary chronic pain treatment environment. The current study represents the first large-scale examination of these issues, with two major aims: (1) to elucidate the differences between FBSS patients and other chronic lumbar pain patients; and (2) to clarify the role of injections in interdisciplinary treatment, particularly with FBSS patients. A total of 128 chronic lumbar pain patients who presented for treatment at an interdisciplinary center were included in the study. Patients completed various measures at pre-, mid-, and post-treatment intervals, including physical, functional, and psychosocial measures. Overall, both FBSS and Non-FBSS patients reported significantly decreased pain and disability, and significant improvements in physical and psychosocial functioning after interdisciplinary treatment. However, Non-FBSS patients were associated with greater reductions in self-reported pain and disability than FBSS patients. On the other hand, FBSS patients were significantly more improved on physical therapy measures, including Activities of Daily Living, Strength, and Fear of Exercise. Statistical comparisons of Injection (INJ) and No-Injection (No-INJ) groups yielded few significant findings.

The management of secondary gain and loss in medicolegal settings: strengths and weaknesses.

Individuals with chronic illness and disability are among the most difficult patients to treat. The health-care provider is faced with an array of physical, psychological, and social factors, requiring adoption of a biopsychosocial approach to treatment. This approach necessitates consideration of the benefits for the patient of remaining ill and disabled. These benefits have been termed the "secondary gains" of illness, and they may serve to perpetuate disability and illness behavior. This paper focuses on secondary gain and loss issues in patients with chronic, nonprogressive illness associated with chronic disability, who are evaluated and treated in medicolegal settings. In working with this population of patients, the health-care provider is faced not only with the usual secondary gains of illness (e.g., escape from family responsibilities), but must also deal with the myriad of secondary gain issues unique to medicolegal settings (e.g., seeking financial compensation). Consequently, identifying and managing secondary gain issues can be quite challenging. A model for managing these issues is presented here,following a more general discussion of secondary gain and related concepts. This model has proven very useful when incorporated into an effective rehabilitation program, such as the functional restoration approach to treating chronic musculoskeletal disorders. However, shortcomings of this model for managing secondary gain have become apparent. These shortcomings, and methods for overcoming them, are discussed. The overall purpose of this paper is to improve the health-care provider's ability to identify and manage both simple and complex secondary gain issues.

Treatment- and cost-effectiveness of early intervention for acute low-back pain patients: a one-year prospective study.

In an attempt to prevent acute low-back pain from becoming a chronic disability problem, an earlier study developed a statistical algorithm which accurately identified those acute low-back pain patients who were at high risk for developing such chronicity. The major goal of the present study was to evaluate the clinical effectiveness of employing an early intervention program with these high-risk patients in order to prevent the development of chronic disability at a 1-year follow-up. Approximately 700 acute low-back pain patients were screened for their high-risk versus low-risk status. On the basis of this screening, high-risk patients were then randomly assigned to one of two groups: a functional restoration early intervention group (n = 22), or a nonintervention group (n = 48). A group of low-risk subjects (n = 54) who did not receive any early intervention was also evaluated. All these subjects were prospectively tracked at 3-month intervals starting from the date of their initial evaluation, culminating in a 12-month follow-up. During these follow-up evaluations, pain disability and socioeconomic outcomes (such as return-to-work and healthcare utilization) were assessed. Results clearly indicated that the high-risk subjects who received early intervention displayed statistically significant fewer indices of chronic pain disability on a wide range of work, healthcare utilization, medication use, and self-report pain variables, relative to the high-risk subjects who do not receive such early intervention. In addition, the high-risk nonintervention group displayed significantly more symptoms of chronic pain disability on these variables relative to the initially low-risk subjects. Cost-comparison savings data were also evaluated. These data revealed that there were greater cost savings associated with the early intervention group versus the no early intervention group. The overall results of this study clearly demonstrate the treatment- and cost-effectiveness of an early intervention program for acute low-back pain patients.

Secondary loss and pain-associated disability: theoretical overview and treatment implications.

In the area of occupational pain disability, a major barrier to effective rehabilitation of patients may be the extensive personal losses that can arise as secondary features of chronic pain disability. In this review, we discuss the concept of secondary loss and how it can have a profound impact on patients with occupational pain disability. Such secondary loss issues are extremely important to consider in any rehabilitation program in order to ensure the most comprehensive and compassionate treatment of these patients. We discuss the types of intervention that may be employed within the context of interdisciplinary rehabilitation programs.

Psychotropic medication in chronic spinal disorders.

BACKGROUND CONTEXT: Optimal treatment of nonmalignant chronic spinal disorders (CSDs) may require the use of one or more nonopioid psychotropic medications. Vast research literature has documented high rates of psychiatric disorders in patients with CSDs. Psychotropic medications are one type of effective treatment for these disorders. Many medications of this type are also used as adjuvants to primary analgesic medications. PURPOSE: Physicians treating CSDs may have little training and experience in prescribing psychotropic medications. Further, they may possess limited information about the efficacy of these types of medications in treating psychiatric disorders comorbid with CSDs or as adjunctive analgesics. Because of the wide variety (antidepressants, anxiolytics, sleep-promoting agents, anticonvulsants, neuroleptics, muscle relaxants) and numerous indications for psychiatric medications, a concise review of the use of psychotropic medications with CSD patients is offered for the spine specialist. STUDY DESIGN: A systematic review of the contemporary English literature on psychotropic medications in the CSD population. METHODS: A computerized search of MEDLINE was performed on all English literature published from 1982 to August 2002. RESULTS: Psychotropic medications have been found to be very efficacious in the large subgroup of patients with CSDs with psychiatric comorbidity, particularly patients with the common constellation of depression, anxiety, excessive somatic complaints, insomnia and irritability. Although the type of medication indicated depends on the particular psychiatric syndrome(s), antidepressants have been found to be extremely useful with the constellation described above. There is less evidence to support the use of nonopioid psychotropic medications in the treatment of nociceptive pain, although clinical experience indicates that some individuals demonstrate a marked analgesic response. Research support for the efficacy of particular psychotropic medications in treating neuropathic pain is stronger, although more controlled research is clearly needed. CONCLUSIONS: Psychotropic medications are extremely useful in the treatment of psychiatric disorders comorbid with CSDs and modestly useful as analgesic adjuvants, particularly with pain of neuropathic etiology. Familiarity with these medications will aid the primary treating physician in optimizing outcomes in this difficult group of patients.

Chronic pain and psychopathology: research findings and theoretical considerations.

OBJECTIVE: Numerous studies have documented a strong association between chronic pain and psychopathology. Previous research has shown that chronic pain is most often associated with depressive disorders, anxiety disorders, somatoform disorders, substance use disorders, and personality disorders. The primary objective of this review article is to describe the nature of the relationship between chronic pain and each of these types of psychopathology. In addition, this article will explore how each of these disorders are expressed within the context of chronic pain, with a consideration of both diagnostic and treatment issues. METHODS: Medline and PsychLit searches of the chronic pain/psychopathology literature from 1980 through 2000 were conducted using the keywords chronic pain, psychopathology, psychiatric disorders, and psychological disorders. RESULTS: The relationship between chronic pain and psychopathology has generated substantial empirical and theoretical interest, with depressive disorders receiving much of the attention. CONCLUSIONS: Although no single theoretical model can fully explain the causal relationship between chronic pain and psychopathology, a diathesis-stress model is emerging as the dominant overarching theoretical perspective. In this model, diatheses are conceptualized as preexisting, semidormant characteristics of the individual before the onset of chronic pain that are then activated and exacerbated by the stress of this chronic condition, eventually resulting in diagnosable psychopathology.
