A Cross-Sectional Analysis of Clinical Outcomes Following Chiropractic Care in Veterans With and Without Post-Traumatic Stress Disorder

This study was a cross-sectional analysis of clinical outcomes for 130 veteran patients with neck or low back complaints completing a course of care within the chiropractic clinic at the VA of Western New York in 2006. Multivariate analysis of variance (MANOVA) was utilized, comparing baseline and discharge scores for both the neck and low back regions and for those patients with and without post-traumatic stress disorder (PTSD). Patients with PTSD (n = 21) experienced significantly lower levels of score improvement than those without PTSD (n = 119) on self-reported outcome measures of neck and low back disability. These findings, coupled with the theorized relationships between PTSD and chronic pain, suggest that the success of conservative forms of management for veteran patients with musculoskeletal disorders may be limited by the presence of PTSD. Further research is warranted to examine the potential contributions of PTSD on chiropractic clinical outcomes with this unique patient population.

Preliminary analysis of posttraumatic stress disorder screening within specialty clinic setting for OIF/OEF veterans seeking care for neck or back pain

Escalating prevalence estimates of posttraumatic stress disorder (PTSD) among recently returning Operation Iraqi Freedom/Operation Enduring Freedom (OIF/OEF) veterans highlight the need for early detection and management for reducing chronic mental illness and disability. Because PTSD and chronic pain are common comorbid conditions among veterans, PTSD screening within specialty clinic settings addressing musculoskeletal pain may be of value. This retrospective study evaluated measures of diagnostic value for the PTSD Checklist (PCL) for a sample (n = 79) of OIF/OEF veterans seeking care for neck or back pain within a Department of Veterans Affairs specialty clinic. Because published accounts of optimal PCL cutoff scores vary considerably, we used receiver operating characteristic curves to identify whether the optimal PCL cutoff score for the sample differed from a conventional cutoff score of 50. A clinical psychologist experienced in diagnosing and managing PTSD confirmed the diagnosis of PTSD for 37 veterans through a review of clinical records. The prevalence of diagnosed PTSD was 46.8%, with an optimal PCL cutoff score of 44. These findings may guide future research and influence clinical practice regarding PTSD screening for recently returning veterans with chronic pain.

Primary care utilization among veterans with chronic musculoskeletal pain: a retrospective chart review.

OBJECTIVE Patients with chronic pain have been shown to be more frequent utilizers of primary care, a contributor to increased health care costs. This study aimed to clarify which patient factors predict primary care utilization among veterans with chronic pain. DESIGN Data were gathered from the electronic medical records of veterans who used Veterans Affairs primary care services from 2003 to 2009 in upstate New York. Chronic pain cases (N = 792) were those veterans diagnosed with a musculoskeletal condition of the hip, knee, or lower back during two or more primary care encounters over a period ≥ 3 months. Cases were frequency matched by age to controls, or those veterans who did not have a chronic musculoskeletal condition of the hip, knee, or lower back. Demographic information, medical and psychiatric diagnoses, medication use, and other health-related factors were used in regression models to predict primary care utilization. RESULTS Cases consistently accrued more primary care encounters than controls during each year of the observation period. Cases also accrued more encounters from specialty medicine clinics, chronic pain clinics, and behavioral health clinics co-located in primary care. The contribution of mental health factors to care utilization differed by case-control status. Diagnosis of depression and substance use disorders were predictors of care utilization only among controls, whereas anxiety disorders, use of anxiolytics, and adjustment disorders were predictors only among cases. Cases with a co-occurring anxiety disorder had a greater than twofold increased risk (odds ratio = 2.36, 95% confidence interval = 1.32-4.22) of being in the top 10% of the distribution of total primary care utilization. CONCLUSIONS Mental health conditions that commonly co-occur with chronic musculoskeletal pain contribute to greater health care utilization. Improved screening and early intervention for these disorders in primary care may improve patient outcomes and stem high rates of care utilization of veterans.

An Analysis of the Integration of Chiropractic Services Within the United States Military and Veterans' Health Care Systems

OBJECTIVES The purpose of this article is to compare chiropractic integration within the health care systems of the Department of Defense and Department of Veterans Affairs and to identify practices and policies that may either support or challenge the extent of chiropractic integration within those systems. METHODS As subject matter experts and providers within these systems, our team reviewed enacted legislation, policies, and the literature pertinent to chiropractic practice in Department of Defense and Department of Veterans Affairs medical facilities, and identified opportunities and threats pertinent to integration. RESULTS We identified 9 areas wherein potential opportunities and threats to integration existed, including legislative history, programmatic growth, leadership structure, employment status of providers, clinical work duties, patient access, patient demographics, academic affiliations, and research. CONCLUSION These findings provide a higher level of understanding regarding the current state and future direction of chiropractic service integration within these integrated health care systems.

Consultation Request Patterns, Patient Characteristics, and Utilization of Services within a Veterans Affairs Medical Center Chiropractic Clinic

A retrospective review of completed chiropractic consultations in 2006 (N = 354) was carried out to investigate consultation request patterns, patient characteristics, and the utilization of chiropractic services within the Department of Veterans Affairs of Western New York Health Care System. Primary care was the main source of patients with variation in the volume of consultation requests among providers. The average chiropractic patient was a 55-year-old male with low back pain who was overweight or obese with 27.43% service-connected disability. Post-traumatic stress disorder was diagnosed in 16.44%. The mean number of patient visits was minimized by following outcome-based practice parameters. Management consisted mainly of spinal manipulative therapy and mobilization techniques. Veteran chiropractic patients differed demographically from those in the general public who are predominantly female and younger. The implications of these differences on clinical outcomes and chiropractic clinical education are unclear and serve as the stimulus for additional research.

Chiropractic Care and Public Health: Answering Difficult Questions About Safety, Care Through the Lifespan, and Community Action

The purpose of this collaborative summary is to document current chiropractic involvement in the public health movement, reflect on social ecological levels of influence as a profession, and summarize the relationship of chiropractic to the current public health topics of: safety, health issues through the lifespan, and effective participation in community health issues. The questions that are addressed include: Is spinal manipulative therapy for neck and low-back pain a public health problem? What is the role of chiropractic care in prevention or reduction of musculoskeletal injuries in children? What ways can doctors of chiropractic stay updated on evidence-based information about vaccines and immunization throughout the lifespan? Can smoking cessation be a prevention strategy for back pain? Does chiropractic have relevance within the VA Health Care System for chronic pain and comorbid disorders? How can chiropractic use cognitive behavioral therapy to address chronic low back pain as a public health problem? What opportunities exist for doctors of chiropractic to more effectively serve the aging population? What is the role of ethics and the contribution of the chiropractic profession to public health? What public health roles can chiropractic interns perform for underserved communities in a collaborative environment? Can the chiropractic profession contribute to community health? What opportunities do doctors of chiropractic have to be involved in health care reform in the areas of prevention and public health? What role do citizen-doctors of chiropractic have in organizing community action on health-related matters? How can our future chiropractic graduates become socially responsible agents of change?

Spinal Manipulative Therapy for Chronic Lower Back Pain in Older Veterans A Prospective, Randomized, Placebo-Controlled Trial

Introduction: Chronic lower back pain (CLBP) is problematic in older veterans. Spinal manipulative therapy (SMT) is commonly utilized for CLBP in older adults, yet there are few randomized placebo-controlled trials evaluating SMT. Methods: The purpose of the study was to compare the effectiveness of SMT to a sham intervention on pain (Visual Analogue Scale, SF-36 pain subscale), disability (Oswestry Disability Index), and physical function (SF-36 subscale, Timed Up and Go) by performing a randomized placebo-controlled trial at 2 Veteran Affairs Clinics. Results: Older veterans (≥ 65 years of age) who were naive to chiropractic were recruited. A total of 136 were included in the study with 69 being randomly assigned to SMT and 67 to sham intervention. Patients were treated 2 times per week for 4 weeks assessing outcomes at baseline, 5, and 12 weeks postbaseline. Both groups demonstrated significant decrease in pain and disability at 5 and 12 weeks. At 12 weeks, there was no significant difference in pain and a statistically significant decline in disability scores in the SMT group when compared to the sham intervention group. There were no significant differences in adverse events between the groups. Conclusions: The SMT did not result in greater improvement in pain when compared to our sham intervention; however, SMT did demonstrate a slightly greater improvement in disability at 12 weeks. The fact that patients in both groups showed improvements suggests the presence of a nonspecific therapeutic effect.

Chiropractic management of mechanical low back pain secondary to multiple-level lumbar spondylolysis with spondylolisthesis in a United States Marine Corps veteran: a case report

OBJECTIVE This case report describes the evaluation and conservative management of mechanical low back pain secondary to multiple-level lumbar spondylolysis with spondylolisthesis in a United States Marine Corps veteran within a Veterans Affairs Medical Center chiropractic clinic. CLINICAL FEATURES The 43-year-old patient had a 20-year history of mechanical back pain secondary to an injury sustained during active military duty. He had intermittent radiation of numbness and tingling involving the right lower extremity distal to the knee. Radiographs of the lumbosacral region demonstrated a grade I spondylolisthesis of L3 in relation to L4 and a grade II spondylolisthesis of L4 in relation to L5 secondary to bilateral pars interarticularis defects. There was marked narrowing of the L4-5 disk space with associated subchondral sclerosis. INTERVENTION AND OUTCOME A course of conservative management consisting of 10 treatments including lumbar flexion/distraction and activity modification was provided over an 8-week period. Despite the long-standing nature of the complaint and underlying multiple-level lumbar spondylolysis with spondylolisthesis, there was a 25% reduction in low back pain severity on the numeric rating scale and a 22% reduction in perceived disability related to low back pain on the Revised Oswestry Disability Questionnaire. CONCLUSIONS Conservative management is considered to be the standard of care for spondylolysis and should be explored in its various forms for symptomatic low back pain patients who present without neurologic deficits and with spondylolisthesis below grade III. The response to treatment for the veteran patient in this case suggests that lumbar flexion/distraction may serve as a safe and effective component of conservative management of mechanical low back pain for some patients with spondylolysis and spondylolisthesis.

Chiropractic Management for Veterans with Neck Pain: A Retrospective Study of Clinical Outcomes

OBJECTIVE The purpose of this study was to report demographic characteristics, chiropractic treatment methods and frequency, and clinical outcomes for chiropractic management of neck pain in a sample of veteran patients. METHODS This is a retrospective case series of 54 veterans with a chief complaint of neck pain who received chiropractic care through a Veterans Health Administration medical center. Descriptive statistics and paired t tests were used with the numeric rating scale and Neck Bournemouth Questionnaire serving as the outcome measures. A minimum clinically important difference was set as 30% improvement from baseline for both outcomes. RESULTS The mean number of chiropractic treatments was 8.7. For the numeric rating scale, the mean raw score improvement was 2.6 points, representing 43% change from baseline. For the Neck Bournemouth Questionnaire, the mean raw score improvement was 13.9 points, representing 33% change from baseline. For both measures, 36 (67%) patients met or exceeded the minimum clinically important difference. CONCLUSION Mean chiropractic clinical outcomes were both statistically significant and clinically meaningful for this sample of veterans presenting with neck pain.

When Demand Exceeds Supply: Allocating Chiropractic Services at VA Medical Facilities

ABSTRACT Objective With limited Veterans Affairs (VA) doctors of chiropractic (DCs) in geographically disparate VA medical facilities of varying capacities, the potential of demand for care exceeding supply can be realized. The purpose of this paper is two-fold. First the authors propose a model for VA chiropractic clinic operation to maximize appropriate access to care and utility of services provided. Second the authors suggest an ethical basis for making potentially difficult administrative decisions regarding the distribution of chiropractic services within VA medical facilities. Discussion The authors suggest practices to maximize clinic efficiency and effectiveness under conditions of demand for chiropractic services in excess of available supply. In terms of access, the service agreement and gatekeeper instructions for ordering a consultation should help shape demand and avoid inappropriate consultation requests. Consultation requests should also be screened by VA DCs. Scheduling should work to minimize no-shows through a patient reminder system. With regard to utilization, the delivery of chiropractic services should be made more efficient through the use of templates within the electronic medical record. Lastly, evidence-based outcome measures should be applied to objectify clinical progress and help to identify clinical end points in care. Utilitarian theory serves as a possible ethical framework to guide VA DCs in maximizing the benefits of chiropractic care for our veteran patient population as resources allow. Conclusions VA doctors of chiropractic must balance the demand for patient care with the limited availability of resources. Suggested practices may enhance appropriate access to and efficient utilization of chiropractic care within the VHA.
