OBJECTIVE: This study examined potential risk factors associated with healthcare utilization among patients with spine (i.e., neck and back) pain. METHODS: A two-stage sampling approach examined spine pain episodes of care among veterans with a yearly outpatient visit for six consecutive years. Descriptive and bivariate statistics, followed by logistic regression analyses, examined baseline characteristics of veterans with new episodes of care who either continued or discontinued spine pain care. A multivariable logistic regression model examined correlates associated with seeking continued spine pain care. RESULTS: Among 331,908 veterans without spine pain episodes of care during the two-year baseline observation period, 16.5% (n = 54,852) had a new episode of care during the following two-year observation period. Of those 54,852 veterans, 37,025 had an outpatient visit data during the final two-year follow-up period, with 53.7% (n = 19,865) evidencing continued spine pain care. Those with continued care were more likely to be overweight or obese, non-smokers, Army veterans, have higher education, and had higher rates of diagnoses of all medical and mental health conditions examined at baseline. Among several important findings, women had 13% lower odds of continued care during the final two-year observation period, OR 0.87 (0.81, 0.95). CONCLUSIONS: A number of important demographics and clinical correlates were associated with increased likelihood of seeking new and continued episodes of care for spine pain; however, further examination of risk factors associated with healthcare utilization for spine pain is indicated.

Objective: Chronic pain is a significant problem in patients living with hepatitis C virus (HCV). Tobacco smoking is an independent risk factor for high pain intensity among veterans. This study aims to examine the independent associations with smoking and HCV on pain intensity, as well as the interaction of smoking and HCV on the association with pain intensity. Design/Particpants: Cross-sectional analysis of a cohort study of veterans of Operations Enduring Freedom/Iraqi Freedom/New Dawn (OEF/OIF/OND) who had at least one visit to a Veterans Health Administration (VHA) primary care clinic between 2001 and 2014. Methods: HCV was identified using ICD-9 codes from electronic medical records (EMRs). Pain intensity, reported on a 0-10 numeric rating scale, was categorized as none/mild (0-3) and moderate/severe (4-10). Results: Among 654,841 OEF/OIF/OND veterans (median age [interquartile range] = 26 [23-36] years), 2,942 (0.4%) were diagnosed with HCV. Overall, moderate/severe pain intensity was reported in 36% of veterans, and 37% were current smokers. The adjusted odds of reporting moderate/severe pain intensity were 1.23 times higher (95% confidence interval [CI] = 1.14-1.33) for those with HCV and 1.26 times higher (95% CI = 1.25-1.28) for current smokers. In the interaction model, there was a significant Smoking Status x HCV interaction (P = 0.03). Among veterans with HCV, smoking had a significantly larger association with moderate/severe pain (adjusted odds ratio [OR] = 1.50, P < 0.001) than among veterans without HCV (adjusted OR = 1.26, P < 0.001). Conclusions: We found that current smoking is more strongly linked to pain intensity among veterans with HCV. Further investigations are needed to explore the impact of smoking status on pain and to promote smoking cessation and pain management in veterans with HCV.

BACKGROUND: Despite strong evidence for the effectiveness of non-pharmacological pain treatment modalities (NPMs), little is known about the prevalence or correlates of NPM use. OBJECTIVE: This study examined rates and correlates of NPM use in a sample of veterans who served during recent conflicts. DESIGN: We examined rates and demographic and clinical correlates of self-reported NPM use (operationalized as psychological/behavioral therapies, exercise/movement therapies, and manual therapies). We calculated descriptive statistics and examined bivariate associations and multivariable associations using logistic regression. PARTICIPANTS: Participants were 460 veterans endorsing pain lasting > /= 3 months who completed the baseline survey of the Women Veterans Cohort Study (response rate 7.7%. MAIN MEASURES: Outcome was self-reported use of NPMs in the past 12 months. KEY RESULTS: Veterans were 33.76 years old (SD = 10.72), 56.3% female, and 80.2% White. Regarding NPM use, 22.6% reported using psychological/behavioral, 50.9% used exercise/movement and 51.7% used manual therapies. Veterans with a college degree (vs. no degree; OR = 2.51, 95% CI = 1.46, 4.30, p = 0.001) or those with worse mental health symptoms (OR = 2.88, 95% CI = 2.11, 3.93, p < 0.001) were more likely to use psychological/behavioral therapies. Veterans who were female (OR = 0.63, 95% CI = 0.43, 0.93, p = 0.02) or who used non-opioid pain medications (OR = 1.82, 95% CI = 1.146, 2.84, p = 0.009) were more likely to use exercise/movement therapies. Veterans who were non-White (OR = 0.57, 95% CI = 0.5, 0.94, p = 0.03), with greater educational attainment (OR = 2.11, 95% CI = 1.42, 3.15, p < 0.001), or who used non-opioid pain medication (OR = 1.71, 95% CI = 1.09, 2.68, p = 0.02) were more likely to use manual therapies. CONCLUSIONS: Results identified demographic and clinical characteristics among different NPMs, which may indicate differences in veteran treatment preferences or provider referral patterns. Further study of provider referral patterns and veteran treatment preferences is needed to inform interventions to increase NPM utilization. Research is also need to identify demographic and clinical correlates of clinical outcomes related to NPM use.

OBJECTIVE: Pain and smoking are highly prevalent among Veterans. Studies in non-Veteran populations have reported higher pain intensity among current smokers compared with nonsmokers and former smokers. We examined the association of smoking status with reported pain intensity among Veterans of Operations Enduring Freedom, Iraqi Freedom, and New Dawn (OEF/OIF/OND). DESIGN: The sample consisted of OEF/OIF/OND Veterans who had at least one visit to Veterans Affairs (2001-2012) with information in the electronic medical record for concurrent smoking status and pain intensity. The primary outcome measure was current pain intensity, categorized as none to mild (0-3); moderate (4-6); or severe ( > /=7); based on a self-reported 11-point pain numerical rating scale. Multivariable logistic regression analyses were used to assess the association of current smoking status with moderate to severe ( > /=4) pain intensity, controlling for potential confounders. RESULTS: Overall, 50,988 women and 355,966 men Veterans were examined. The sample mean age was 30 years; 66.3% reported none to mild pain; 19.8% moderate pain; and 13.9% severe pain; 37% were current smokers and 16% former smokers. Results indicated that current smoking [odds ratio (OR) = 1.29 (95% confidence intervals (CI) = 1.27-1.31)] and former smoking [OR = 1.02 (95% CI = 1.01-1.05)] were associated with moderate to severe pain intensity, controlling for age, service-connected disability, gender, obesity, substance abuse, mood disorders, and Post Traumatic Stress Disorder. CONCLUSIONS: We found an association between current smoking and pain intensity. This effect was attenuated in former smokers. Our study highlights the importance of understanding reported pain intensity in OEF/OIF/OND Veterans who continue to smoke.
