Complementary and alternative medicine use among veterans with chronic noncancer pain

We describe prior use and willingness to try complementary and alternative medicine (CAM) among 401 veterans experiencing chronic noncancer pain and explore differences between CAM users and nonusers. Participants in a randomized controlled trial of a collaborative intervention for chronic pain from five Department of Veterans Affairs (VA) primary care clinics self-reported prior use and willingness to try chiropractic care, massage therapy, herbal medicines, and acupuncture. Prior CAM users were compared with nonusers on demographic characteristics, pain-related clinical characteristics, disease burden, and treatment satisfaction. A majority of veterans ( n = 327, 82%) reported prior use of at least one CAM modality, and nearly all (n = 399, 99%) were willing to try CAM treatment for pain. Chiropractic care was the least preferred option, whereas massage therapy was the most preferred (75% and 96%, respectively). CAM users were less likely to have service-connection disabilities (54% vs 68%; chi square = 4.64, p = 0.03) and reported having spent a larger percentage of their lives in pain (26% vs 20%; Z = 1.40, p = 0.04) than nonusers. We detected few differences between veterans who had tried CAM and those who had not, suggesting that CAM may have broad appeal among veterans with chronic pain. Implications for VA policy and practice and for clinicians treating veterans with chronic pain are discussed.

Identifying Risk Factors for Marijuana Use Among Veterans Affairs Patients

Cannabis is the most widely used drug in the United States, and its use carries negative health consequences; however, universal screening for cannabis use is cumbersome. If data commonly collected in the primary care setting (eg, use of alcohol, smoking status, and depression symptoms) could predict cannabis use, then providers can implement targeted marijuana screening in high-risk groups. We reviewed Behavioral Health Laboratory data collected between 2003 and 2006 from 5512 patients referred by Veterans Affairs primary care clinics for potential mental health needs. Logistic regression was used to determine the predictors of past year marijuana use. A total of 11.5% of the sample reported using marijuana in the past year. Age, gender, other drug use, presence of alcohol use disorders, smoking status, depressive disorders, posttraumatic stress disorder, anxiety disorders, and psychotic symptoms, individually, were associated with the patients' use of marijuana during the past year. When controlling for age, race, and gender in a logistic regression analyses, only other drug use, alcohol use disorder, and smoking status were linked to past year marijuana use. Patients were 5.4 (95% confidence interval [CI] 4.3-6.7) times more likely to have used marijuana during the past year if they used another illicit drug during the past year. Those with alcohol use disorder diagnosis or current smokers were 2.3 (95% CI 1.9-2.8) and 1.5 times (95% CI 1.3-1.7), respectively, more likely to have used marijuana during the past year. Receiver operating characteristic curve (area under curve = 0.79) represents good sensitivity and specificity of the model, correctly classifying 88.4% of the past year marijuana users. Identifying patients at high risk for cannabis use may facilitate targeted screening and provision of interventions in primary care. Patients who screen positive for cigarette use, alcohol abuse or dependence, or have evidence of other illicit drug use could be considered for cannabis screening.

PTSD symptoms, hazardous drinking, and health functioning among U.S.OEF and OIF veterans presenting to primary care

Posttraumatic stress disorder (PTSD) and alcohol abuse both are negatively associated with health, and alcohol misuse may mediate the relationship between PTSD and functional health outcomes. The present study tested for such mediation using self-report measures of PTSD symptoms, hazardous alcohol use, and health functioning in 151 U.S. veterans (136 men and 15 women) of the wars in Iraq and Afghanistan recruited from a Veterans Affairs primary care clinic. Based on established cut scores, 39.1% screened positive for PTSD and 26.5% screened positive for hazardous drinking. PTSD symptoms and hazardous drinking were significantly correlated with each other and with health functioning. Hazardous drinking was found to partially mediate the relationship between PTSD and functional mental health, but not physical health.

A Randomized Trial of a Low-Carbohydrate Diet vs Orlistat Plus a Low-Fat Diet for Weight Loss

Two potent weight loss therapies, a low-carbohydrate, ketogenic diet (LCKD) and orlistat therapy combined with a low-fat diet (O + LFD), are available to the public but, to our knowledge, have never been compared. Overweight or obese outpatients (n = 146) from the Department of Veterans Affairs primary care clinics in Durham, North Carolina, were randomized to either LCKD instruction (initially, <20 g of carbohydrate daily) or orlistat therapy, 120 mg orally 3 times daily, plus low-fat diet instruction (<30% energy from fat, 500-1000 kcal/d deficit) delivered at group meetings over 48 weeks. Main outcome measures were body weight, blood pressure, fasting serum lipid, and glycemic parameters. The mean age was 52 years and mean body mass index was 39.3 (calculated as weight in kilograms divided by height in meters squared); 72% were men, 55% were black, and 32% had type 2 diabetes mellitus. Of the study participants, 57 of the LCKD group (79%) and 65 of the O + LFD group (88%) completed measurements at 48 weeks. Weight loss was similar for the LCKD (expected mean change, -9.5%) and the O + LFD (-8.5%) (P = .60 for comparison) groups. The LCKD had a more beneficial impact than O + LFD on systolic (-5.9 vs 1.5 mm Hg) and diastolic (-4.5 vs 0.4 mm Hg) blood pressures (P < .001 for both comparisons). High-density lipoprotein cholesterol and triglyceride levels improved similarly within both groups. Low-density lipoprotein cholesterol levels improved within the O + LFD group only, whereas glucose, insulin, and hemoglobin A(1c) levels improved within the LCKD group only; comparisons between groups, however, were not statistically significant. In a sample of medical outpatients, an LCKD led to similar improvements as O + LFD for weight, serum lipid, and glycemic parameters and was more effective for lowering blood pressure. clinicaltrials.gov Identifier: NCT00108524.

Health Care Utilization and Its Costs for Depressed Veterans With and Without Comorbid PTSD Symptoms

This study examined health care utilization and costs of care among Veterans Affairs (VA) patients with depression and with or without symptoms of comorbid posttraumatic stress disorder (PTSD). Cross-sectional comparisons of health care utilization and costs were conducted with VA administrative data for a sample of veterans from a randomized trial of collaborative care depression treatment in ten VA primary care clinics across five states. Patients with depression or dysthymia were included in the study, and those who were acutely suicidal or had probable bipolar disorder were excluded. The sample of 606 patients was mainly male, white, and aged 55 or older. Health care utilization, costs, and medication data from VA administrative databases were analyzed over 12 months. Patients with depression and PTSD (screen score > or =3) were more emotionally distressed, had more frequent mental health specialty visits (6.91 versus 1.68, p<.001), more total outpatient visits (26.16 versus 19.94, p<.001), and correspondingly higher outpatient mental health care costs over the previous 12 months compared with depressed patients without PTSD. Antidepressants were prescribed to a higher proportion of depressed patients with PTSD (61% versus 40%). Patients with PTSD and depression had greater utilization of specialty mental health treatments and antidepressant medications and higher mental health care costs in the previous 12 months than depressed patients without PTSD. As military personnel return from Iraq, both VA and non-VA health care providers need to plan for an increase in outpatient mental health services and costs, particularly among depressed veterans who also have PTSD.

The effects of smoking cessation on the risk of chronic obstructive pulmonary disease exacerbations.

Smoking cessation has been demonstrated to reduce the rate of loss of lung function and mortality among patients with mild to moderate chronic obstructive pulmonary disease (COPD). There is a paucity of evidence about the effects of smoking cessation on the risk of COPD exacerbations. We sought to examine whether smoking status and the duration of abstinence from tobacco smoke is associated with a decreased risk of COPD exacerbations. We assessed current smoking status and duration of smoking abstinence by self-report. Our primary outcome was either an inpatient or outpatient COPD exacerbation. We used Cox regression to estimate the risk of COPD exacerbation associated with smoking status and duration of smoking cessation. We performed a cohort study of 23,971 veterans who were current and past smokers and had been seen in one of seven Department of Veterans Affairs (VA) primary care clinics throughout the US. In comparison to current smokers, ex-smokers had a significantly reduced risk of COPD exacerbation after adjusting for age, comorbidity, markers of COPD severity and socio-economic status (adjusted HR 0.78, 95% CI 0.75-0.87). The magnitude of the reduced risk was dependent on the duration of smoking abstinence (adjusted HR: quit < 1 year, 1.04; 95% CI 0.87-1.26; 1-5 years 0.93, 95% CI 0.79-1.08; 5-10 years 0.84, 95% CI 0.70-1.00; > or = 10 years 0.65, 95% CI 0.58-0.74; linear trend <0.001). Smoking cessation is associated with a reduced risk of COPD exacerbations, and the described reduction is dependent upon the duration of abstinence.

Bupropion as a Possible Treatment Option for Restless Legs Syndrome

To describe a case of restless legs syndrome (RLS) successfully managed with bupropion. A 45-year-old female presented to a Veterans Affairs primary care clinic with a history of chronic insomnia. Her complicated history of treatment failure to sedative-hypnotic agents, continued sleep disturbances, and complaints of intolerable leg sensations fostered collaboration between a psychiatrist and pharmacist to identify effective treatment. Further review of her medical history and subjective complaints led to a diagnosis of RLS. Based on this new diagnosis, she was prescribed several Food and Drug Administration-approved and alternative agents recommended for the management of RLS. Unfortunately, each medication resulted in a variety of intolerable adverse effects, limiting the list of treatment options. Although not widely used for RLS, bupropion XL (Wellbutrin XL) 150 mg daily was initiated, resulting in resolution of RLS within 3 days. RLS can be an extremely disabling disorder and affects many people. For most patients, dopamine agonists are the treatment of choice for symptomatic relief. However, for patients unable to tolerate this drug class, small trials and case reports have identified alternative agents. This case supports findings from other cases suggesting a beneficial response with bupropion for the management of RLS. Bupropion may be a treatment option for patients who have RLS and are unable to tolerate dopamine agonists.

Cumulative Anticholinergic Exposure Is Associated with Poor Memory and Executive Function in Older Men

To examine the longitudinal relationship between cumulative exposure to anticholinergic medications and memory and executive function in older men. Prospective cohort study. A Department of Veterans Affairs primary care clinic. Five hundred forty-four community-dwelling men aged 65 and older with diagnosed hypertension. The outcomes were measured using the Hopkins Verbal Recall Test (HVRT) for short-term memory and the instrumental activity of daily living (IADL) scale for executive function at baseline and during follow-up. Anticholinergic medication use was ascertained using participants' primary care visit records and quantified as total anticholinergic burden using a clinician-rated anticholinergic score. Cumulative exposure to anticholinergic medications over the preceding 12 months was associated with poorer performance on the HVRT and IADLs. On average, a 1-unit increase in the total anticholinergic burden per 3 months was associated with a 0.32-point (95% confidence interval (CI)= 0.05-0.58) and 0.10-point (95% CI=0.04-0.17) decrease in the HVRT and IADLs, respectively, independent of other potential risk factors for cognitive impairment, including age, education, cognitive and physical function, comorbidities, and severity of hypertension. The association was attenuated but remained statistically significant with memory (0.29, 95% CI=0.01-0.56) and executive function (0.08, 95% CI=0.02-0.15) after further adjustment for concomitant non-anticholinergic medications. Cumulative anticholinergic exposure across multiple medications over 1 year may negatively affect verbal memory and executive function in older men. Prescription of drugs with anticholinergic effects in older persons deserves continued attention to avoid deleterious adverse effects.

Sexual assault, mental health, and service use among male and female veterans seen in Veterans Affairs primary care clinics: A multi-site study

This study examined the nature and prevalence of sexual assault (SA), as well as its relationship to psychiatric sequelae and service use, among the veteran population. We performed a secondary data analysis of a cross-sectional dataset consisting of 643 male and 173 female veterans seen in four Veterans Affairs (VA) primary care clinics. Original data were obtained through semi-structured clinic assessments, structured telephone interviews, and medical chart reviews. Analyses included descriptive statistics, chi-square, analysis of variance (ANOVA), and logistic regression. The lifetime prevalence of SA was 38% among women and 6% among men. Of veterans reporting a history of SA, most experienced child sexual abuse and sexual revictimization. SA victims also had a more extensive trauma history and demonstrated greater psychological impairment in comparison to veterans reporting other types of trauma. However, only 25% of male SA survivors and 38% of female SA survivors used mental health services in the past year. These findings suggest that VA primary care clinics may benefit from expanding the current mandated screen for military sexual trauma to include lifetime experiences and trauma-related symptoms, thereby connecting more veterans with needed mental health services.

Unhealthy Alcohol Use Is Associated with Medication Nonadherence

The effects of unhealthy alcohol use (the spectrum from risky use through dependence) on the management of coexistent medical conditions have not been well described. In a secondary analysis of prospective data from trial at Veterans Affairs primary care clinics, investigators studied more than 20,000 patients with prescriptions for statin, …

Age Differences in Posttraumatic Stress Disorder, Psychiatric Disorders, and Healthcare Service Use Among Veterans in Veterans Affairs Primary Care Clinics

Objective To expand our understanding of posttraumatic stress disorder (PTSD) prevalence, its psychiatric characteristics, and service use among elderly veterans in Veterans Affairs (VA) primary care clinics. Methods A cross-sectional, epidemiological design (N = 745) incorporating self-report measures, structured interviews, and chart reviews was used to obtain relevant information for analyses. Results The oldest group of veterans (≥65 years; N = 318) had lower prevalence of most psychiatric diagnoses than the youngest (18–44 years; N = 69) and middle-aged (45–64 years; N = 358) groups. Despite having higher rates of combat exposure, veterans in the oldest group (6.3%) had one-third the prevalence of PTSD than those in the middle-aged group (18.6%). A similar pattern was found across other psychiatric diagnoses. For example, those in the oldest group (7.5%) had one-third the prevalence of major depression as those in the two younger groups (21.7% and 22.9%). These differences were maintained after controlling for relevant demographic covariates (race, sex). Results from examination of VA health care service use across the three groups were consistent with the findings that the oldest veteran group is functioning significantly better across mental health domains. Conclusion Elderly veterans who use VA primary care services evidence lower rates of PTSD and other psychiatric disorders, and they use significantly less VA mental health services. They also do not appear to show evidence of worse physical health functioning or use VA health care services or disability benefits at a meaningfully higher rate than their younger counterparts.

Clinical Inertia: A Common Barrier to Changing Provider Prescribing Behavior

A cross-sectional content analysis nested within a randomized, controlled trial was conducted to collect information on provider responses to computer alerts regarding guideline recommendations for patients with suboptimal hypertension care. Participants were providers who cared for 1,017 patients with uncontrolled hypertension on a single antihypertensive agent within Veterans Affairs primary care clinics. All reasons for action or inaction were sorted into a framework to explain the variation in guideline adaptation. The 184 negative provider responses to computer alerts contained explanations for not changing patient treatment; 76 responses to the alerts were positive, that is, the provider was going to make a change in antihypertensive regimen. The negative responses were categorized as: inertia of practice (66%), lack of agreement with specific guidelines (5%), patient-based factors (17%), environmental factors (10%), and lack of knowledge (2%). Most of the 135 providers classified as inertia of practice indicated, "Continue current medications and I will discuss at the next visit." The median number of days until the next visit was 45 days (interquartile range, 29 to 78 days). Clinical inertia was the primary reason for failing to engage in otherwise indicated treatment change in a subgroup of patients. A framework was provided as a taxonomy for classification of provider barriers.

Best Practices: Depression Screening in a VA Primary Care Clinic

In 1998 the U.S. Department of Veterans Affairs (VA) mandated annual depression screening at all VA primary care clinics. The VA Medical Center, New Orleans, implemented a four-item screening tool. The authors report on an evaluation of the screening program. Of 1,100 patients visiting the clinic during a one-month period, 1,068 (97 percent) were screened at that visit or at some point in the previous 12 months. Of the 70 patients who screened positive for depression, 50 (71 percent) were offered at least one treatment modality or psychiatric referral. The findings establish benchmarks for screening administration and for follow-through on positive screens. The authors describe features of the electronic medical record that contributed to the successful implementation of this best practice.

Female Veterans Seeking Medical Care at Veterans Affairs Primary Care Clinics: Psychiatric and Medical Illness Burden and Service Use

ABSTRACT Objective: To examine rates of medical and psychiatric disorders among 187 female veterans recruited at four Veterans Affairs Medical Centers (VAMCs), the recognition of such disorders by VAMC care providers, and the use of relevant medical and mental health services by women both within and outside of the VA setting. Methods: We used a cross-sectional, epidemiological design incorporating self-report measures, structured interviews, and chart reviews to obtain relevant information for analyses. Results: Forty-four percent (43.9%) of women met criteria for at least one psychiatric disorder; 34.0% of these women met criteria for two or more additional psychiatric diagnoses, and concordance rates between interview and chart diagnoses were low. Ninety-five percent (95.2%) of women had a medical condition noted in their charts; 86.6% had two or more additional medical conditions, and a significant number of women had both medical and psychiatric diagnoses. Forty-four percent (43.9%) of women with an identified mental health condition received specialized mental health care by the VA in the past year. Conclusions: Findings from this study suggest that female veterans treated in VAMCs had significant medical and psychiatric problems, and these women might not be getting their health care needs adequately met through the VA health care system. In light of our findings, we discuss relevant implications and future directions for research.

Clinical practice guideline implementation strategy patterns in Veterans Affairs primary care clinics.

The Department of Veterans Affairs (VA) mandated the system-wide implementation of clinical practice guidelines (CPGs) in the mid-1990s, arming all facilities with basic resources to facilitate implementation; despite this resource allocation, significant variability still exists across VA facilities in implementation success. This study compares CPG implementation strategy patterns used by high and low performing primary care clinics in the VA. Descriptive, cross-sectional study of a purposeful sample of six Veterans Affairs Medical Centers (VAMCs) with high and low performance on six CPGs. One hundred and two employees (management, quality improvement, clinic personnel) involved with guideline implementation at each VAMC primary care clinic. MEASURES; Participants reported specific strategies used by their facility to implement guidelines in 1-hour semi-structured interviews. Facilities were classified as high or low performers based on their guideline adherence scores calculated through independently conducted chart reviews. High performing facilities (HPFs) (a) invested significantly in the implementation of the electronic medical record and locally adapting it to provider needs, (b) invested dedicated resources to guideline-related initiatives, and (c) exhibited a clear direction in their strategy choices. Low performing facilities exhibited (a) earlier stages of development for their electronic medical record, (b) reliance on preexisting resources for guideline implementation, with little local adaptation, and (c) no clear direction in their strategy choices. A multifaceted, yet targeted, strategic approach to guideline implementation emphasizing dedicated resources and local adaptation may result in more successful implementation and higher guideline adherence than relying on standardized resources and taxing preexisting channels.

Racial Differences in Psychiatric Symptom Patterns and Service Use in VA Primary Care Clinics

The purpose of this study was to assess racial differences in psychopathology and service use in a sample of African-American and Caucasian veterans. African-American (N=253) and Caucasian (N=460) veterans from primary care clinics at four Department of Veterans Affairs (VA) medical centers were compared on rates of trauma, posttraumatic stress disorder (PTSD), other psychiatric diagnoses, functional status, and use of VA services and benefits. A cross-sectional, epidemiologic design incorporating self-report measures, structured interviews, and chart reviews was used. With the exception of substance abuse or dependence diagnoses and use of substance abuse treatment and urgent care services, few racial differences emerged. Overall, the findings suggest that African-American and Caucasian veterans, including those with PTSD, do not differ significantly in psychopathology or in their use of VA benefits and services.

Impact of institutional review board practice variation on observational health services research.

To describe, qualitatively and quantitatively, the impact of a review by multiple institutional review boards (IRBs) on the conduct of a multisite observational health services research study. DATA SOURCE AND SETTING: Primary data collection during 2002, 2003, and 2004 at 43 United States Department of Veterans Affairs (VA) primary care clinics. Explanatory sequential mixed methods design incorporating qualitative and quantitative elements in sequence. DATA COLLECTION AND ABSTRACTION METHODS: Field notes and documents collected by research staff during a multisite observational health services research study were used in thematic analysis. Themes were quantified descriptively and merged with timeline data. Approximately 4,680 hours of staff time over a 19-month period were devoted solely to the IRB process. Four categories of phenomena impacting research were observed: (1) Recruitment, retention, and communication issues with local site principal investigators (PIs). Local PIs had no real role but were required by IRBs. Twenty-one percent of sites experienced turnover in local PIs, and local PI issues added significant delay to most sites. (2) Wide variation in standards applied to review and approval of IRB applications. The study was designed to be qualified under U.S. government regulations for expedited review. One site exempted it from review (although it did not qualify for exemption), 10 granted expedited review, 31 required full review, and one rejected it as being too risky to be permitted. Twenty-three required inapplicable sections in the consent form and five required HIPAA (Health Insurance Portability and Accountability Act of 1996) consent from physicians although no health information was asked of them. Twelve sites requested, and two insisted upon, provisions that directly increased the risk to participants. (3) Multiple returns for revision of IRB applications, consent documents, and ancillary forms. Seventy-six percent of sites required at least one resubmission, and 15 percent of sites required three or more (up to six) resubmissions. Only 12 percent of sites required any procedural or substantive revision; most resubmissions were editorial changes to the wording of the consent document. (4) Process failures (long turnaround times, lost paperwork, difficulty in obtaining necessary forms, unavailability of key personnel at IRBs). The process required from 52 to 798 (median 286) days to obtain approval at each site. Several features of the IRB system as currently configured impose costly burdens of administrative activity and delay on observational health services research studies, and paradoxically decrease protection of human subjects. Central review with local opt-out, cooperative review, or a system of peer review could reduce costs and improve protection of human subjects.

Prevalence of posttraumatic stress disorder in Veterans Affairs primary care clinics

Although posttraumatic stress disorder (PTSD) is relatively common in community epidemiologic surveys (5–6% for men, 10–12% for women), and psychiatric patients with PTSD are known to have poor functioning and high levels of psychiatric comorbidity, there are no studies that address PTSD prevalence, functioning, and burden in primary care settings. This article reports on (1) the prevalence of PTSD using Diagnostic and Statistical Manual of Mental Disorders-Fourth Edition diagnostic criteria in Veterans Affairs (VA) primary care settings, (2) associated sociodemographic characteristics and comorbidities, (3) functional status related to PTSD, (4) the extent to which PTSD was recognized by providers and (5) health services use patterns (including specialty mental health) of PTSD patients. Patients were randomly selected from those who had an outpatient visit in FY 1999 at one of four VA hospitals; 888 patients consented (74.1% of 1198 contacted); 746 patients (84.0% of consenting patients; 62.3% of contacted patients) were reached for telephone diagnostic interviews. Diagnostic interviews with the Clinician Administered PTSD Scale yielded estimates of current PTSD prevalence of 11.5%. At statistically significant levels, PTSD was positively associated with a variety of comorbid psychiatric disorders, war zone service, age <65 years, not working, less formal education and decreased functioning. Of patients diagnosed with PTSD by study procedures, 12-month medical record review indicated that providers identified only 46.5% and only 47.7% had used mental health specialty services. PTSD-positive [PTSD(+)] patients who used mental health care in the past 12 months were more apt to be identified as having PTSD than nonmental health service users (78.0% vs. 17.8%). Although PTSD(+) patients had more medical record diagnoses than PTSD-negative [PTSD(−)] patients (6.28 vs. 4.95), their use of primary care, urgent care and inpatient care was not different from PTSD(−) patients.

Randomized controlled trial of the impact of intensive patient education on compliance with fecal occult blood testing

Randomized controlled trials have demonstrated that fecal occult blood testing (FOBT) reduces colorectal cancer (CRC) mortality. However, patient compliance with FOBT is low and this is one of the major barriers to CRC screening. To determine whether intensive patient education increases FOBT card return rates. Randomized controlled trial. Department of Veterans Affairs primary care clinic. Seven hundred eighty-eight patients who were referred for FOBT. Patients were randomly allocated to receive either intensive (n=396) or standard (n=392) patient education. Patients in the intensive education group received a one-on-one educational session by primary care nurses on the importance of CRC screening, were instructed on how to properly collect stool specimens for FOBT, and were given a 2-page handout on CRC screening. Patients in the standard education group only received the FOBT cards and written instructions from the manufacturer on how to properly collect stool specimens for FOBT. Patients in the intensive education group were more likely to return the FOBT cards (65.9% vs 51.3%; P<.001) and called the clinic with additional questions less often (1.5% vs 5.9%; P=.001) than the standard education group. The median time to return the FOBT cards was significantly shorter in the intensive education group (36 vs 143 days; P<.001 by log-rank test). However, the proportion of patients who had a positive FOBT did not differ in the two groups (4.6% vs 6.0%; P=.51). Intensive patient education significantly improved patient compliance with FOBT. Future studies to evaluate additional educational strategies to further improve patient compliance with CRC screening are warranted.
