Caregiver and provider perspectives on dual VA and Medicare Part D medication use in veterans with suspected dementia or cognitive impairment.

PURPOSE: Many older veterans with dementia fill prescriptions through both Veterans Affairs (VA) and Medicare Part D benefits. Dual VA/Part D medication use may have unintended negative consequences in terms of prescribing safety and quality. We aimed to characterize benefits and drawbacks of dual VA/Part D medication use in veterans with dementia or cognitive impairment from the perspectives of caregivers and providers. METHODS: This was a qualitative study based on semistructured telephone interviews of 2 groups: (1) informal caregivers accompanying veterans with suspected dementia or cognitive impairment to visits at a VA Geriatric Evaluation and Management clinic (n = 11) and (2) VA healthcare providers of veterans with dementia who obtained medications via VA and Part D (n = 12). We conducted semistructured telephone interviews with caregivers and providers about benefits and drawbacks of dual VA/Part D medication use. Interview transcripts were subjected to qualitative content analysis to identify key themes. RESULTS: Caregivers and providers both described cost and convenience benefits to dual VA/Part D medication use. Caregivers reported drawbacks including poor communication between VA and non-VA providers and difficulty managing medications from multiple systems. Providers reported potential safety risks including communication barriers, conflicting care decisions, and drug interactions. CONCLUSION: Results of this study allow for understanding of potential policy interventions to better manage dual VA/Part D medication use for older veterans with dementia or cognitive impairment at a time when VA is expanding access to non-VA care.

Caring for older veterans with chronic low back pain using a geriatric syndrome approach: Rationale and methods for the aging back clinics (ABC) trial.

The purpose of the ongoing trial is to improve care of older Veterans with chronic low back pain (CLBP, i.e., low back pain for ≥6 months on ≥ half the days). Current CLBP care is limited by being either overly spine-focused or non-specifically prescribed and both approaches frequently lead to suboptimal reduction in pain and improvement in function. Through prior studies we have laid the foundation for a patient-centered approach to care for older Veterans with CLBP in which the spine is a source of vulnerability but not the sole treatment target. The approach considers CLBP a geriatric syndrome, a final common pathway for the expression of multiple contributors rather than a disease of the spine. We describe here the rationale and design of a randomized controlled trial to test the efficacy of an older Veteran-centered approach to CLBP care in "Aging Back Clinics (ABCs)" compared with Usual Care (UC). Three hundred thirty Veterans age 65-89 with CLBP will be randomized to ABCs or UC and followed for 12 months after randomization. We will assess the impact of ABCs on our primary outcome of pain-associated disability with the Oswestry Disability Index at 6 and 12 months, and secondary outcomes of pain intensity, health-related quality of life, balance confidence, mobility and healthcare utilization. If shown efficacious, the approach tested in ABCs has the potential to transform the care of older adults with CLBP by improving the quality of life for millions, reducing morbidity and saving substantial healthcare costs.

Aging Back Clinics-a Geriatric Syndrome Approach to Treating Chronic Low Back Pain in Older Adults: Results of a Preliminary Randomized Controlled Trial.

OBJECTIVE: Treating chronic low back pain (CLBP) with spine-focused interventions is common, potentially dangerous, and often ineffective. This preliminary trial tests the feasibility and efficacy of caring for CLBP in older adults as a geriatric syndrome in Aging Back Clinics (ABC). DESIGN: Randomized controlled trial. SETTING: Outpatient clinics of two VA Medical Centers. SUBJECTS: Fifty-five English-speaking veterans aged 60-89 with CLBP and no red flags for serious underlying illness, prior back surgery, dementia, impaired communication, or uncontrolled psychiatric illness. METHODS: Participants were randomized to ABC care or usual care (UC) and followed for six months. ABC care included 1) a structured history and physical examination to identify pain contributors, 2) structured participant education, 3) collaborative decision-making, and 4) care guided by condition-specific algorithms. Primary outcomes were low back pain severity (0-10 current and seven-day average/worst pain) and pain-related disability (Roland Morris). Secondary outcomes included the SF-12 and health care utilization. RESULTS: ABC participants experienced significantly greater reduction in seven-day average (-1.22 points, P = 0.023) and worst pain (-1.70 points, P = 0.003) and SF-12 interference with social activities (50.0 vs 11.5%, P = 0.0030) at six months. ABC participants were less likely to take muscle relaxants (16.7 vs 42.3%, P = 0.0481). Descriptively, UC participants were more likely to experience pain-related emergency room visits (45.8% vs 30.8%) and to be exposed to non-COX2 nonsteroidal anti-inflammatory drugs (73.1% vs 54.2%). CONCLUSIONS: These preliminary data suggest that ABC care for older veterans with CLBP is feasible and may reduce pain and exposure to other potential morbidity.

GRECC Connect: Geriatrics Telehealth to Empower Health Care Providers and Improve Management of Older Veterans in Rural Communities.

A telehealth program supports meaningful partnerships between urban geriatric specialists and rural health care providers to facilitate increased access to specialty care.

Biopsychosocial Profiles and Functional Correlates in Older Adults with Chronic Low Back Pain: A Preliminary Study.

OBJECTIVE: To describe key peripheral and central nervous system (CNS) conditions in a group of older adults with chronic low back pain (CLBP) and their association with pain severity and self-reported and performance-based physical function. DESIGN: Cross-sectional. SETTING: Outpatient VA clinics. SUBJECTS: Forty-seven community-dwelling veterans with CLBP (age 68.0 ± 6.5 years, range = 60-88 years, 12.8% female, 66% white) participated. METHODS: Data were collected on peripheral pain generators-body mass index, American College of Rheumatology hip osteoarthritis criteria, neurogenic claudication (i.e., spinal stenosis), sacroiliac joint (SIJ) pain, myofascial pain, leg length discrepancy (LLD), and iliotibial band pain; and CNS pain generators-anxiety (GAD-7), depression (PHQ-9), insomnia (Insomnia Severity Index), maladaptive coping (Fear Avoidance Beliefs Questionnaire, Cognitive Strategies Questionnaire), and fibromyalgia (fibromyalgia survey). Outcomes were pain severity (0 to 10 scale, seven-day average and worst), self-reported pain interference (Roland Morris [RM] questionnaire), and gait speed. RESULTS: Approximately 96% had at least one peripheral CLBP contributor, 83% had at least one CNS contributor, and 80.9% had both peripheral and CNS contributors. Of the peripheral conditions, only SIJ pain and LLD were associated with outcomes. All of the CNS conditions and SIJ pain were related to RM score. Only depression/anxiety and LLD were associated with gait speed. CONCLUSIONS: In this sample of older veterans, CLBP was a multifaceted condition. Both CNS and peripheral conditions were associated with self-reported and performance-based function. Additional investigation is required to determine the impact of treating these conditions on patient outcomes and health care utilization.

Use of Clinical Video Telehealth as a Tool for Optimizing Medications for Rural Older Veterans with Dementia.

Community-Based Outpatient Clinics (CBOCs) allow delivery of primary care to rural veterans who are far from a main Veterans Affairs (VA) campus. However, CBOCs often do not have physicians with geriatric training. We used a clinical video telehealth (CVT) dementia service (Teledementia clinic) based in the Pittsburgh VA Healthcare System to optimize dementia patients' medications and potentially inappropriate medications (PIMs). We analyzed 199 CVT patient encounters from 1 January 2016 to 31 December 2016 and compared different medication changes per encounter between the initial CVT consults and the follow-up visits for all medications and PIMs as listed in the 2015 Beers Criteria, to see if there was a decrease of each kind of change, which is being used as a surrogate for optimization. We found that initial CVT consults, compared to follow-up visits, had greater medications added (0.731 vs. 0.434, p = 0.0092), total overall medications changes (1.769 vs. 1.130, p = 0.0078), and the stopping of 2015 Beers Criteria PIMs (0.208 vs. 0.072, p = 0.0255) per encounter. The fewer PIMs discontinued and fewer medication additions in follow-ups implies that our patients' medications tend to stay optimized between visits. The teledementia service represents a novel way to provide geriatric assistance to CBOC VA primary care physicians for rural veterans with dementia.

Creation of an Interprofessional Teledementia Clinic for Rural Veterans: Preliminary Data.

The teledementia clinic is a new model of care that expands the reach of specialized geriatric and dementia care using clinical video telehealth (CVT) to rural veterans, who frequently lack access to specialty care. The clinic is a Veterans Affairs (VA) Geriatric Research, Education, and Clinical Center clinical demonstration project. It is located in the Pittsburgh VA Healthcare System tertiary referral hospital and serves veterans in affiliated rural community-based outpatient clinics (CBOCs). Rural CBOC primary care providers refer clinic patients, or referral is according to previous cognitive impairment diagnosis in a VAPHS geriatric clinic. Patients undergo interprofessional dementia assessment by a geriatrician, geropsychologist, geriatric psychiatrist or neurologist, and social worker using CVT technology. Metrics for clinic evaluation included rural patients served and savings in travel time, distance, and costs. Assessments collected depended upon individual presentation and included cognitive tests, geriatric depression scales, functional assessment, and the Zarit Burden Interview. A patient satisfaction survey was created and administered. In the first year, 95 individuals were served in 156 clinic visits and 251 interprofessional provider encounters. Of patients served, 61 lived in rural ZIP codes, 72 were diagnosed with dementia, 19 were diagnosed with mild cognitive impairment, and four were found to have primarily psychiatric diagnoses rather than cognitive impairment. The average Functional Assessment Staging of Alzheimer's Disease Scale score was 4.3 ± 1.3. This clinic model demonstrates that CVT technology is a feasible means of providing interprofessional dementia evaluations and follow-up to rural presidents.

Deconstructing Chronic Low Back Pain in the Older Adult-Step by Step Evidence and Expert-Based Recommendations for Evaluation and Treatment: Part VII: Insomnia.

OBJECTIVE : To present the seventh in a series of articles designed to deconstruct chronic low back pain (CLBP) in older adults. This article focuses on insomnia and presents a treatment algorithm for managing insomnia in older adults, along with a representative clinical case. METHODS : A modified Delphi process was used to develop the algorithm and supportive materials. A multidisciplinary expert panel representing expertise in health psychology and sleep medicine developed the algorithm and supporting documents that were subsequently refined through an iterative process of input from a primary care provider panel. RESULTS : We present an illustrative clinical case and an algorithm to help guide the care of older adults with insomnia, an important contributor to CLBP and disability. Multicomponent cognitive behavioral therapy for insomnia (CBTI) and similar treatments (e.g., brief behavioral treatment for insomnia [BBTI]) are the recommended first-line treatment. Medications should be considered only if BBTI/CBTI is suboptimal or not effective and should be prescribed at the lowest effective dose for short periods of time (< 90 days). CONCLUSIONS : Insomnia is commonly comorbid with CLBP in older adults and should be routinely evaluated and treated because it is an important contributor to pain and disability. The algorithm presented was structured to assist primary care providers in planning treatment for older adults with CLBP and insomnia.

Deconstructing Chronic Low Back Pain in the Older Adult-Step by Step Evidence and Expert-Based Recommendations for Evaluation and Treatment. Part VI: Lumbar Spinal Stenosis.

OBJECTIVE: . To present the sixth in a series of articles designed to deconstruct chronic low back pain (CLBP) in older adults. This article focuses on the evaluation and management of lumbar spinal stenosis (LSS), the most common condition for which older adults undergo spinal surgery. METHODS: . The evaluation and treatment algorithm, a table articulating the rationale for the individual algorithm components, and stepped-care drug recommendations were developed using a modified Delphi approach. The Principal Investigator, a five-member content expert panel and a nine-member primary care panel were involved in the iterative development of these materials. The illustrative clinical case was taken from the clinical practice of a contributor's colleague (SR). RESULTS: . We present an algorithm and supportive materials to help guide the care of older adults with LSS, a condition that occurs not uncommonly in those with CLBP. The case illustrates the importance of function-focused management and a rational approach to conservative care. CONCLUSIONS: . Lumbar spinal stenosis exists not uncommonly in older adults with CLBP and management often can be accomplished without surgery. Treatment should address all conditions in addition to LSS contributing to pain and disability.

Deconstructing Chronic Low Back Pain in the Older Adult: Step by Step Evidence and Expert-Based Recommendations for Evaluation and Treatment: Part IV: Depression.

OBJECTIVE: To present the fourth in a series of articles designed to deconstruct chronic low back pain (CLBP) in older adults. The series presents CLBP as a syndrome, a final common pathway for the expression of multiple contributors rather than a disease localized exclusively to the lumbosacral spine. Each article addresses one of twelve important contributors to pain and disability in older adults with CLBP. This article focuses on depression. METHODS: The evaluation and treatment algorithm, a table articulating the rationale for the individual algorithm components, and stepped-care drug recommendations were developed using a modified Delphi approach. The Principal Investigator, a three-member content expert panel, and a nine-member primary care panel were involved in the iterative development of these materials. The algorithm was developed keeping in mind medications and other resources available within Veterans Health Administration (VHA) facilities. As panelists were not exclusive to the VHA, the materials can be applied in both VHA and civilian settings. The illustrative clinical case was taken from one of the contributor's clinical practice. RESULTS: We present an algorithm and supportive materials to help guide the care of older adults with depression, an important contributor to CLBP. The case illustrates an example of a complex clinical presentation in which depression was an important contributor to symptoms and disability in an older adult with CLBP. CONCLUSIONS: Depression is common and should be evaluated routinely in the older adult with CLBP so that appropriately targeted treatments can be planned and implemented.

Deconstructing chronic low back pain in the older adult--Step by step evidence and expert-based recommendations for evaluation and treatment part III: Fibromyalgia syndrome.

OBJECTIVE: To present the third in a series of articles designed to deconstruct chronic low back pain (CLBP) in older adults. The series presents CLBP as a syndrome, a final common pathway for the expression of multiple contributors rather than a disease localized exclusively to the lumbosacral spine. Each article addresses one of 12 important contributors to pain and disability in older adults with CLBP. This article focuses on fibromyalgia syndrome (FMS). METHODS: A modified Delphi approach was used to create the evaluation and treatment algorithm, the table discussing the rationale behind each of the algorithm components, and the stepped-care drug recommendations. The team involved in the creation of these materials consisted of a principal investigator, a 5-member content expert panel, and a 9-member primary care panel. The evaluation and treatment recommendations were based on availability of medications and other resources within the Veterans Health Administration (VHA) facilities. However, non-VHA panelists were also involved in the development of these materials, which can be applied to both VA and civilian settings. The illustrative clinical case was taken from the clinical practice of the principal investigator. RESULTS: Following expert consultations and a review of the literature, we developed an evaluation and treatment algorithm with supporting materials to aid in the care of older adults with CLBP who have concomitant FMS. A case is presented that demonstrates the complexity of pain evaluation and management in older patients with CLBP and concomitant FMS. CONCLUSIONS: Recognition of FMS as a common contributor to CLBP in older adults and initiating treatment targeting both FMS and CLBP may lead to improved outcomes in pain and disability.

Deconstructing Chronic Low Back Pain in the Older Adult-Step by Step Evidence and Expert-Based Recommendations for Evaluation and Treatment: Part II: Myofascial Pain.

OBJECTIVE: To present an algorithm of sequential treatment options for managing myofascial pain (MP) in older adults, along with a representative clinical case. METHODS: A modified Delphi process was used to synthesize evidence-based recommendations. A multidisciplinary expert panel developed the algorithm, which was subsequently refined through an iterative process of input from a primary care physician panel. RESULTS: We present an algorithm and supportive materials to help guide the care of older adults with MP, an important contributor to chronic low back pain (CLBP). Addressing any perpetuating factors should be the first step of managing MP. Patients should be educated on self-care approaches, home exercise, and the use of safe analgesics when indicated. Trigger point deactivation can be accomplished by manual therapy, injection therapy, dry needling, and/or acupuncture. CONCLUSIONS: The algorithm presented gives a structured approach to guide primary care providers in planning treatment for patients with MP as a contributor to CLBP.

Deconstructing chronic low back pain in the older adult--step by step evidence and expert-based recommendations for evaluation and treatment: part I: Hip osteoarthritis.

OBJECTIVE: To present the first in a series of articles designed to deconstruct chronic low back pain (CLBP) in older adults. The series presents CLBP as a syndrome, a final common pathway for the expression of multiple contributors rather than a disease localized exclusively to the lumbosacral spine. Each article addresses one of twelve important contributors to pain and disability in older adults with CLBP. This article focuses on hip osteoarthritis (OA). METHODS: The evaluation and treatment algorithm, a table articulating the rationale for the individual algorithm components, and stepped-care drug recommendations were developed using a modified Delphi approach. The Principal Investigator, a five-member content expert panel and a nine-member primary care panel were involved in the iterative development of these materials. The algorithm was developed keeping in mind medications and other resources available within Veterans Health Administration (VHA) facilities. As panelists were not exclusive to the VHA, the materials can be applied in both VHA and civilian settings. The illustrative clinical case was taken from one of the contributor's clinical practice. RESULTS: We present an algorithm and supportive materials to help guide the care of older adults with hip OA, an important contributor to CLBP. The case illustrates an example of complex hip-spine syndrome, in which hip OA was an important contributor to disability in an older adult with CLBP. CONCLUSIONS: Hip OA is common and should be evaluated routinely in the older adult with CLBP so that appropriately targeted treatment can be designed.

Optimizing strategies to improve interprofessional practice for veterans, part 1.

INTRODUCTION: Interprofessional patient care is a well-recognized path that health care systems are striving toward. The Veteran's Affairs (VA) system initiated interprofessional practice (IPP) models with their Geriatric Evaluation and Management (GEM) programs. GEM programs incorporate a range of specialties, including but not limited to, medicine, nursing, social work, physical therapy and pharmacy, to collaboratively evaluate veterans. Despite being a valuable resource, they are now faced with significant cut-backs, including closures. The primary goal of this project was to assess how the GEM model could be optimized at the Pittsburgh, Pennsylvania VA to allow for the sustainability of this important IPP assessment. Part 1 of the study evaluated the IPP process using program, patient, and family surveys. Part 2 examined how well the geriatrician matched patients to specialists in the GEM model. This paper describes Part 1 of our study. METHODS: THREE STRATEGIES WERE USED: 1) a national GEM program survey; 2) a veteran/family satisfaction survey; and 3) an absentee assessment. RESULTS: Twenty-six of 92 programs responded to the GEM IPP survey. Six strategies were shared to optimize IPP models throughout the country. Of the 34 satisfaction surveys, 80% stated the GEM clinic was beneficial, 79% stated their concerns were addressed, and 100% would recommend GEM to their friends. Of the 24 absentee assessments, the top three reasons for missing the appointments were transportation, medical illnesses, and not knowing/remembering about the appointment. Absentee rate diminished from 41% to 19% after instituting a reminder phone call policy. DISCUSSION: Maintaining the sustainability of IPP programs is crucial for the health of our veterans. This project uncovered tools to improve the GEM IPP model for our veterans that can be incorporated nationally. Despite the lengthy nature of IPP models, patients and families appreciated the thoroughness, requested transportation and food, and responded well to reminder phone calls. A keen eye on these issues and concomitant medical complexity needs to be observed when planning IPP models to ensure sustainability.

A multisite geriatric education program for rural providers in the Veteran Health Care System (GRECC-Connect).

Older patients who live in rural areas often have limited access to specialty geriatric care, which can help in identifying and managing geriatric conditions associated with functional decline. Implementation of geriatric-focused practices among rural primary care providers has been limited, because rural providers often lack access to training in geriatrics and to geriatricians for consultation. To bridge this gap, four Geriatric Research, Education, and Clinical Centers, which are centers of excellence across the nation for geriatric care within the Veteran health system, have developed a program utilizing telemedicine to connect with rural providers to improve access to specialized geriatric interdisciplinary care. In addition, case-based education via teleconferencing using cases brought by rural providers was developed to complement the clinical implementation efforts. In this article, the authors review these educational approaches in the implementation of the clinical interventions and discuss the potential advantages in improving implementation efforts.

Racial differences in medication use among older, long-stay Veterans Affairs nursing home care unit patients.

OBJECTIVE: To examine racial differences in medication use by older long-stay Veterans Affairs Nursing Home Care Unit (NHCU) patients. DESIGN: Longitudinal study. SETTINGS: 133 Veterans Affairs NHCUs. PARTICIPANTS: Three thousand four hundred eighty veterans 65 years of age or older admitted between January 1, 2004, and June 30, 2005, for 90 days or more. MAIN OUTCOMES MEASURES: Prevalence of those taking nine or more medications (i.e., polypharmacy) and medications from specific therapeutic medication classes. Racial differences were determined using 0.05 level chi-squared tests. RESULTS: The sample consisted of 14.3% who were black. Blacks compared with whites (all comparisons P < 0.05 except where noted) were younger (13.6% vs. 17.4%, older than 85 years of age), had less depression (22.24 vs. 29.79%), less allergies (9.82% vs. 20.36%), and a similar rate of moderate-to severe pain (22.65% vs. 24.05; P = 0.49). The percent of polypharmacy was similar by race (blacks 74.35% vs. whites 71.18%; P = 0.62), as was the prevalence of medication class use with the exceptions that blacks were less likely than whites to take central nervous system (CNS) medications (75.75% vs. 80.14%; P = 0.02) and antihistamines (13.03% vs. 16.8%; P = 0.04). Specifically, blacks were less likely than whites to receive a selective serotonin-reuptake inhibitor (SSRI) antidepressant (20.84% vs. 27.17%; P < 0.01) or a second-generation antihistamine (3.41% vs. 6.51%; P < 0.01), but more likely than whites to receive opioids (14.63% vs. 11.27%; P = 0.03). CONCLUSION: There appears to be racial differences in the overall use of antihistamines and CNS medications and some of their subclasses.

Consensus guidelines for oral dosing of primarily renally cleared medications in older adults.

OBJECTIVES: To establish consensus oral dosing guidelines for primarily renally cleared medications prescribed for older adults. DESIGN: Literature search followed by a two-round modified Delphi survey. SETTING: A nationally representative survey of experts in geriatric clinical pharmacy. PARTICIPANTS: Eleven geriatric clinical pharmacists. MEASUREMENTS: After a comprehensive literature search and review by an investigative group of six physicians (2 general internal medicine, 2 nephrology, 2 geriatrics), 43 dosing recommendations for 30 medications at various levels of renal function were created. The expert panel rated its agreement with each of these 43 dosing recommendations using a 5-point Likert scale (1=strongly disagree to 5=strongly agree). Recommendation-specific means and 95% confidence intervals were estimated. Consensus was defined as a lower 95% confidence limit of greater than 4.0 for the recommendation-specific mean score. RESULTS: The response rate was 81.8% (9/11) for the first round. All respondents who completed the first round also completed the second round. The expert panel reached consensus on 26 recommendations involving 18 (60%) medications. For 10 medications (chlorpropamide, colchicine, cotrimoxazole, glyburide, meperidine, nitrofurantoin, probenecid, propoxyphene, spironolactone, and triamterene), the consensus recommendation was not to use the medication in older adults below a specified level of renal function (e.g., creatinine clearance <30 mL/min). For the remaining eight medications (acyclovir, amantadine, ciprofloxacin, gabapentin, memantine, ranitidine, rimantadine, and valacyclovir), specific recommendations for dose reduction or interval extension were made. CONCLUSION: An expert panel of geriatric clinical pharmacists was able to reach consensus agreement on a number of oral medications that are primarily renally cleared.

Polypharmacy and health beliefs in older outpatients.

BACKGROUND: Polypharmacy is a significant problem among older adults. Patient-related characteristics and beliefs have not been the focus of prior research in this area, which has primarily evaluated the effects of patients' health status and health care system factors. OBJECTIVE: The goal of this research was to determine the prevalence and predictors of unnecessary drug use in older veteran outpatients, with a focus on patient-related factors and health beliefs. METHODS: Community-dwelling veterans aged > or =60 years, with > or =5 self-administered medications per day, not cognitively impaired, able to speak and/or write English, and receiving primary care and medications from a large urban Veterans Affairs Medical Center were eligible for study. Assessment of unnecessary drug use was determined by clinical pharmacists applying the criteria of the Medication Appropriateness Index to each regularly scheduled medication. Those drugs that received an inappropriate rating for indication, effectiveness, or therapeutic duplication were defined as unnecessary. Health beliefs regarding medication use were assessed with decisional balance, self-efficacy, and health locus of control scales. RESULTS: A total of 128 veterans (mean [SD] age, 72.0 [8.9] years; 93.0% white; 93.0% male) were enrolled. Analysis showed that 58.6% of patients had > or =1 unnecessary prescribed drug; the most common reason for a medication being considered inappropriate was lack of effectiveness (41.4%). The most commonly prescribed unnecessary drug classes were central nervous system (19.5%), gastrointestinal (18.0%), and vitamins (16.4%). Factors with tendency for association (P < 0.20) with any unnecessary drug use included race (white), income (<$30,000/year), number of prescription medications (mean [SD], 6.8 [2.8]), and lack of belief in a "powerful other" for their health locus of control. CONCLUSIONS: We found a very high prevalence of unnecessary drug use in this older veteran outpatient population. Race, income, and polypharmacy, as well as health-related beliefs, were central factors associated with unnecessary drug use.
