Comparison of pain and emotional symptoms in soldiers with polytrauma: unique aspects of blast exposure.

OBJECTIVES: To compare the physical and emotional presentation and pain treatment outcomes of service members who sustained polytrauma secondary to blast with those of soldiers injured by other means. DESIGN: Retrospective medical record review. SETTING AND PATIENTS: One of four Veterans Affairs multidisciplinary inpatient Polytrauma Rehabilitation Centers. One hundred twenty-eight Operation Enduring Freedom and Operation Iraqi Freedom military personnel with serious polytrauma injuries and concomitant pain categorized into three groups based on type of injuries: blast injuries, combat injuries other than blast, and noncombat, nonblast injuries. INTERVENTIONS: Intensive, interdisciplinary inpatient rehabilitation and pain treatment. OUTCOME MEASURES: Pain intensity ratings; Functional Independence Measure scores; Rancho Los Amigos levels; and opioid analgesic doses. RESULTS: Service members injured via blast demonstrated a broader spectrum of physical injuries, higher levels of admission and discharge opioid analgesic use, reduced improvement in pain intensity following treatment, and much higher rates of posttraumatic stress disorder and other psychiatric diagnoses than those injured via other means. CONCLUSIONS: Blast injury may be associated with differential physical, emotional, and pain-related symptoms that pose increased challenges for successful treatment.

Assessment and treatment of pain associated with combat-related polytrauma.

Due to the high rates of blast injuries sustained during operations in Iraq and Afghanistan, the number of soldiers returning with massive and multiple wounds is unprecedented. While casualty survival rates have improved dramatically, the extent and impact of these wounds on soldiers' functioning pose unique challenges for their rehabilitation. Pain is highly prevalent in these individuals with polytrauma injuries and is a source of suffering, as well as an impediment to rehabilitation. However, there are a number of obstacles to effective pain treatment in this group of war-injured, including their multiple and severe injuries, the high prevalence of brain injuries, cognitive impairments and emotional distress, the prolonged and intensive rehabilitation process, and the frequent need for repeated follow-up surgeries. As a result, we believe that a comprehensive, interdisciplinary approach to pain treatment is required. In this article we describe the model of pain care that has evolved at the Tampa Polytrauma Rehabilitation Center, which incorporates medical, rehabilitative, cognitive-behavioral, and interventional treatments targeting pain intensity as well as pain-related impairments and coping. We include a case study illustrating some key aspects of our approach.

Pain and combat injuries in soldiers returning from Operations Enduring Freedom and Iraqi Freedom: implications for research and practice.

Operation Enduring Freedom (OEF) and Operation Iraqi Freedom (OIF) have resulted in a growing number of seriously injured soldiers who are evacuated to the United States for comprehensive medical care. Trauma-related pain is an almost universal problem among these war-injured soldiers, and several military and Department of Veterans Affairs initiatives have been implemented to enhance pain care across the continuum of medical services. This article describes several innovative approaches for improving the pain care provided to OEF and OIF military personnel during acute stabilization, transport, medical-surgical treatment, and rehabilitation and presents summary data characterizing the soldiers, pain management services provided, and associated outcomes. We also identify some of the pain assessment, classification, and treatment challenges emerging from work with this population and provide recommendations for future research and practice priorities.

Preliminary evaluation of reliability and criterion validity of Actiwatch-Score.

The restoration of normal physical activity is a primary objective of most chronic pain rehabilitative interventions, yet few clinically practical objective measures of activation exist. Actigraphy is one technology that promises to fill this void in the field of pain outcomes assessment. This study evaluates the measurement properties of one of several commercially available actigraphs: the Actiwatch-Score (AW-S). We conducted separate trials to examine concordance between units when worn concurrently at the same and different body sites and to compare the AW-S to a validated optical three-dimensional motion-tracking system. The data indicate that the AW-S has excellent interunit reliability and good criterion validity, but its intersite reliability varies with activity type. These results suggest that this device, and those like it, warrants further investigation and is likely to yield valuable data regarding the optimal application of this technology.

Anxiety and marital adjustment in patients with implantable cardioverter defibrillator and their spouses.

PURPOSE: Device-related fears are a pervasive psychosocial difficulty that patients with implantable cardioverter defibrillators (ICDs) experience. Spouses also encounter anxieties that may influence patient and spouse adjustment. This study examined anxiety and marital adjustment among ICD patients and spouses, as well as intersex differences between female and male patients. METHODS: Patients and their spouses (N=62) completed separate individual assessment batteries regarding demographics, death anxiety, shock anxiety, general anxiety, and marital adjustment at a single time point during outpatient cardiology visits. RESULTS: Analyses revealed similar general anxiety and marital adjustment among participants, although spouses reported greater shock anxiety than did patients (P = .045). Female ICD patients reported more anxiety related to death and shock and received more shocks, despite equivalent indices of medical severity (P = .002). CONCLUSIONS: This study suggests that spouses of ICD patients experience higher levels of shock anxiety than do patients themselves and that female ICD patients experience higher levels of shock anxiety and death (anxiety than do male patients. Results suggest future research of device specific anxiety and clinical attention devoted to ICD patient spouses and female ICD patients.

Pain among veterans of Operations Enduring Freedom and Iraqi Freedom.

OBJECTIVE: Pain is one of the most frequently reported symptoms by veterans returning from recent overseas military actions. The purpose of the current study was to obtain a preliminary estimate of the prevalence and severity of pain among veterans of Operations Enduring Freedom and Iraqi Freedom (OEF/OIF; N=970). The demographic, etiologic, and diagnostic characteristics of 100 veterans with moderate to severe chronic pain conditions were examined in order to provide a description of this new group of pain patients. DESIGN: This was a historical cohort study that utilized electronic medical record review for all data collection. PATIENTS: All registered OEF/OIF veterans seeking treatment at a Southeastern Veterans' Affairs medical center were included in the initial cohort. In order to describe the characteristics of those with clinically significant pain, 100 veterans were randomly sampled from the subset of patients who reported moderate to severe chronic pain intensity during a medical visit (N=219). RESULTS: Approximately 47% of veterans whose charts included pain score documentation (N=793) reported at least a mild level of current pain. Moderate to severe pain intensity was recorded for 28% (N=219) of those in the initial cohort with pain scores. Diagnoses of musculoskeletal and connective tissue disorders were recorded for 82% of those with chronic conditions (i.e., duration>or=1 month). CONCLUSIONS: The results of this preliminary study suggest that a substantial percentage of OEF/OIF veterans will experience clinically significant pain following their military service.

Measurement of patient fears about implantable cardioverter defibrillator shock: an initial evaluation of the Florida Shock Anxiety Scale.

BACKGROUND: Psychological distress is both a precipitant and a consequence of ICD shock. Therefore, the assessment of patient anxiety and concerns related to receiving an ICD shock may prompt appropriate psychological referrals and treatment. METHODS: The purpose of this study is to assess the initial validity and clinical utility of the Florida Shock Anxiety Scale (FSAS). Seventy-two ICD recipients completed the FSAS. RESULTS: Exploratory factor analysis revealed a two-factor structure with items loading such that Factor 1 could be conceptualized as a Consequence Factor (e.g., fearing creating a scene if the device were to fire) and Factor 2 as a Trigger Factor (e.g., fearing sexual activity). Alpha coefficients suggest good reliability (Cronbach's alpha= 0.91, split-half = 0.92), and FSAS Total Score was moderately correlated (r =-0.65) with total score on the Multidimensional Fear of Death Scale. CONCLUSIONS: Two subscales, labeled consequence of shock and trigger of shock, were established via factor analysis. Collectively the FSAS demonstrates potential utility to assess shock distress and warrants additional investigation.

Do positive health expectations and optimism relate to quality-of-life outcomes for the patient with an implantable cardioverter defibrillator?

PURPOSE: Clinical trials with the implantable cardioverter defibrillator (ICD) have demonstrated desirable outcomes in terms of mortality and morbidity among patients with potentially lethal arrhythmias. This study examined the "resilience factors" of positive health expectations and global optimism prospectively using the general quality-of-life (QOL) scores of newly implanted ICD patients. METHODS: The study enrolled 88 newly implanted ICD patients (mean age, 65.3 +/- 13.2 years; 83% male; 92% white) assessed 8 and 14 months after ICD implantation. A series of 2 x 2 factorial multivariate analyses of covariance were performed to examine the differences between baseline low versus high positive health expectations and baseline low versus high optimism in short- and long-term general QOL scores. RESULTS: After control was used for ejection fraction (mean, 31%), the patients with baseline high positive health expectations reported better general health at a long-term follow-up assessment (P = .002). The patients with high optimism reported better mental health and social functioning at a short-term follow-up assessment (P =. 056), and this finding approached significance at a long-term follow-up assessment (P = .061). CONCLUSIONS: Positive health expectations and optimism are differentially related to various components of QOL. Collectively, these two resilience factors may be targeted in future studies of interventions to improve QOL for ICD patients.

Women and the implantable cardioverter defibrillator: a lifespan perspective on key psychosocial issues.

The clinical success of the implantable cardioverter defibrillator (ICD) in reducing mortality suggests that more women will be receiving ICDs in the future. The impact of ICD therapy in women is unique in western societies; the ICDs scar and lump in the pectoral area can lead to body image concerns due to the emphasis on women's physical attractiveness. Social support and roles are challenged because women's reaction to stress has been characterized by a "tend and befriend" response, involving cultivating and utilizing social networks, rather than the "fight or flight" response more typical of men. In addition, a woman's identity as a caretaker and caregiver can be threatened by the actual and perceived activity limitations imposed by the ICD or the underlying heart condition. Finally, reproductive and sexual health are important issues, as 25 to 50% of patients with ICDs report concerns in this area, but also report discomfort in discussing these concerns with their health care providers. The purpose of the present paper is to review the relevant literature and to identify the unique impact of the psychosocial issues of body image, social support and roles, and sexual development and reproductive functioning for women with ICDs across the lifespan. In the absence of complete empirical research data on the impact of these concerns, hypotheses to test in future research are offered.
