Evaluation of a Pharmacist-Driven Ambulatory Aspirin Deprescribing Protocol.

Recent guidelines indicate that aspirin affords less cardiovascular protection and greater bleeding risks in adults aged > 70 years. Deprescribing potentially inappropriate medications is particularly important in older adults, as this population experiences a high risk of adverse effects and polypharmacy. Limited data are available regarding targeted aspirin deprescribing approaches by pharmacists. The objective of this study was to implement and evaluate the success and feasibility of a pharmacist-led aspirin deprescribing protocol for older adults in a primary care setting. This prospective feasibility study in a US Department of Veterans Affairs ambulatory care pharmacy setting included patients aged ≥ 70 years with documented aspirin use. We reviewed 459 patient records and determined that 110 were eligible for deprescribing. A pharmacistinitiated telephone call was attempted for each eligible patient to discuss the risks and benefits of deprescribing aspirin. The primary outcome was the proportion of patients reached for whom aspirin was discontinued. Secondary outcomes included patient rationale for declining deprescribing and the time to complete the intervention. Of 94 patients reached, 45 (48%) agreed to aspirin deprescribing, 3 (3%) agreed to dose reduction, and 29 (31%) declined the intervention. An additional 17 (18%) had previously stopped aspirin, which led to a medication reconciliation intervention. Pharmacists spent about 2 minutes per record review and 12 minutes on each encounter, including documentation. Implementing a pharmacist-driven aspirin deprescribing protocol in a primary care setting led to the discontinuation of inappropriate aspirin prescribing in nearly half of older adults contacted. The protocol was well accepted by collaborating physicians and feasible for pharmacists to implement, with potential for further dissemination across primary care settings.

Implementation of a pharmacist and student pharmacist–led primary care service to identify and treat rural veterans at risk for osteoporotic fracture

ObjectiveTo develop and implement a pharmacist and student pharmacist–led osteoporosis service to increase dual-energy x-ray absorptiometry (DXA) screening rates among rural veterans and treat those at high risk of osteoporotic fractures. Practice descriptionPharmacists are uniquely positioned to provide direct patient care in the Department of Veterans Affairs ambulatory care setting owing to their broad scope of practice. Clinical Pharmacy Specialists (CPSs) have the authority to order laboratory tests and imaging, prescribe medications, refer patients to specialty services, and monitor patients along with the primary care team. Practice innovationThe implementation of a pharmacist-led osteoporosis primary prevention service using student pharmacists to identify and treat patients has not been previously described in the literature to the authors’ knowledge. Evaluation methodsStudent pharmacists in their third year contacted veterans who met the inclusion criteria for osteoporosis screening. The veterans were offered DXA scans and provided education on the risk factors for osteoporosis. After the DXA scans were completed, the students and the CPS reviewed the results to determine treatment strategies. The primary objective was evaluated by comparing the pre- and post-implementation rates of DXA screening. The other process markers that were evaluated included (1) completed DXA scans, (2) new diagnoses of osteoporosis or osteopenia, (3) patients eligible for treatment on the basis of the DXA screening results, and (4) patients who started oral bisphosphonate therapy. ResultsOf the 232 rural veterans evaluated, 36 had completed DXA scans before this service was implemented. After the service was implemented, 115 veterans completed DXA scans. A total of 57 patients received a new diagnosis, 33 were eligible for therapy, and 12 started oral bisphosphonate therapy after intervention by the CPS. ConclusionThe implementation of a pharmacist-driven osteoporosis screening and treatment service demonstrated an increase in the rate of DXA screening among rural veterans.

Project EVADE: Evaluating the effects of a pharmacist-run transitions of care clinic on hospital readmissions

ObjectivesThe primary objective of this report is to describe the implementation of a pilot pharmacist-run transitions of care clinic. The secondary objective is to present data collected on the impact of this clinic in regard to 30-day, all-cause hospital readmission rates and provider acceptance rates of pharmacist recommendations. SettingThis transitions of care clinic was implemented in a Department of Veterans Affairs ambulatory care center located in Columbus, Ohio. Practice descriptionPharmacists saw high-acuity patients who met inclusion criteria in the transitions of care clinic to complete medication reconciliation, disease state education, and medication counseling. After the visit, the pharmacist made recommendations to the patient’s primary care provider. Practice innovationThis transitions of care clinic is unique in that it is solely pharmacist-run and is located within a primary care setting. EvaluationThe impact of the pharmacist-run clinic was evaluated against a matched control group via a retrospective chart review. A chi-square test was run to assess the difference in 30-day, all-cause hospital readmission rates between patients seen in the transitions of care clinic and those who were not. ResultsThere was a statistically insignificant difference in 30-day, all-cause hospital readmission rates between the transitions of care and control groups (13% vs. 26.1%; P = 0.265). For secondary outcomes assessed in the transitions of care group, 32.9% of medication-related recommendations, 47.4% of laboratory blood work recommendations, and 48.6% of care coordination referrals made by pharmacists were accepted by providers. ConclusionPharmacist involvement in the transitions of care process in the primary care setting through the implementation of a pharmacist-run clinic may decrease the likelihood of hospital readmission.

Association Between Sleep and Physical Function in Older Veterans in an Adult Day Healthcare Program.

To examine whether sleep disturbance is associated with poor physical function in older veterans in an adult day healthcare (ADHC) program. Cross-sectional. One ADHC program in a Veterans Affairs Ambulatory Care Center. Older veterans (N = 50) enrolled in a randomized controlled trial of a sleep intervention program who had complete baseline data. Information on participant characteristics (e.g., age, depression, relationship to caregiver, pain, comorbidity) was collected using appropriate questionnaires. Physical function was measured using activity of daily living (ADL) and instrumental ADL (IADL) total scores from the Older Americans Resources and Services Multidimensional Functional Assessment Questionnaire. Sleep was assessed subjectively (Pittsburgh Sleep Quality Index, Insomnia Severity Index) and objectively (wrist actigraphy). Participants required substantial assistance with ADLs and IADLs. A regression model showed that participant characteristics (marital status, use of sleep medication, comorbidity, posttraumatic stress disorder) and living arrangement (living with a spouse or others) were significantly associated with poor physical function. Poorer objective sleep (total sleep time, total numbers of awakenings, total wake time) was significantly associated with poor physical function, accounting for a significant proportion of the variance other than participant characteristics. Objective measures of nighttime sleep disturbance were associated with poor physical function in older veterans in an ADHC program. Further research is needed to determine whether interventions to improve sleep will delay functional decline in this vulnerable population.

Associations Between Race and Ethnicity and Receipt of Advice About Alcohol Use in the Department of Veterans Affairs

This study sought to identify racial and ethnic differences in rates of alcohol-related advice given to veterans treated in Veterans Affairs (VA) facilities. This was a cross-sectional analysis of data from the VA Survey of the Healthcare Experiences of Patients (SHEP). Participants were 255,522 veterans treated in VA ambulatory clinics in fiscal year 2005. SHEP measures included alcohol consumption questions from the Alcohol Use Disorders Identification Test and an item inquiring whether a VA clinician had given advice about drinking. Logistic regression was used to examine relationships between race and ethnicity categories and receipt of alcohol-related advice. Covariate measures included demographic characteristics and physical and mental component summary scores from the Veterans RAND Health Survey (VR-12). Among veterans who consumed any alcohol, compared with veterans from the other racial or ethnic groups, Asian, Native Hawaiian, or Pacific Islander veterans were less likely to be in the medium and highest alcohol consumption categories and non-Hispanic white veterans were less likely to be in the highest alcohol consumption category (p<.001). In a model adjusting for demographic characteristics, physical and mental health status, and alcohol consumption category, among veterans who consumed any alcohol, those who were non-Hispanic black (odds ratio [OR]=1.65, 95% confidence interval [CI]=1.47-1.84), Hispanic (OR=1.56, CI=1.35-1.80), or non-Hispanic American Indian or Alaska Native (OR=1.56, CI=1.06-2.29) were more likely to report receiving alcohol-related advice, compared with non-Hispanic white veterans. The results suggest that veterans from certain minority groups are more likely than white veterans to report receiving alcohol-related advice in the VA, after the model is adjusted for demographic characteristics, health status, and alcohol consumption. Further research is needed to understand the underlying reasons for observed differences in receipt of alcohol-related advice and the potential clinical implications.

Mental Disorders and Medical Care Utilization of VA Ambulatory Care Patients

In this article, the authors examine patterns of medical services use among the Department of Veterans Affairs (VA) ambulatory care patients who screened positive for posttraumatic stress, depression, or alcohol-related disorders. On the basis of research linking mental disorders with increased use of medical services, the authors hypothesize that even after controlling for age and medical disease comorbidity, patients in VA ambulatory care who screen positive for targeted mental disorders would be more likely to use VA medical services and have higher rates of such use than those who did not screen positive. Baseline data were obtained from the Veterans Health Study, a longitudinal investigation of veterans' health. Four Boston-area VA ambulatory care facilities were used as study sites. A random sample of 2425 participants (mean age = 62) was drawn from male VA ambulatory care patients screened for eligibility during specified periods. Screening measures were Center for Epidemiological Studies-Depression Scale for depression, Posttraumatic Stress Disorder Checklist for posttraumatic stress disorder, and CAGE Questionnaire for alcohol-related disorders with endorsement of prior year consumption for alcohol-related disorders. Prior medical services use was assessed by self-report. Although unadjusted analyses of medical services use revealed clear effects of the screening presence of mental disorders on most outcomes, after adjusting for age and medical comorbidity, almost all these effects were reduced, and some previously nonsignificant results became significant. Findings suggest that healthcare policy and risk adjustment predicated upon the presumed relationship between mental disorders in the aggregate and medical services use should reconsider the important contributions of age, comorbid medical disorders, and specific mental disorder diagnoses.

Posttraumatic Stress Disorder and Health Status

This article examines the association between self-reported prevalence of posttraumatic stress disorder (PTSD) and health status in a sample of 2425 male Department of Veterans Affairs (VA) ambulatory care patients who participated in the Veterans Health Study. Participants were recruited at 1 of 4 VA outpatient clinics in the Boston area. They completed self-report measures of PTSD (using the PTSD Checklist and measures of exposure to traumatic events), depression (using the Center for Epidemiologic Studies--Depression scale), and health status (using the Short-Form-36) and a medical history interview assessing 22 conditions and a history of psychiatric treatment. The screening prevalence of PTSD was 20.2% among all patients (24.3% among those exposed to traumatic events); another 15.5% met the criteria for depression but not PTSD. The health status of patients with either PTSD or depression was significantly worse than that of patients with neither disorder, even after controlling for age, education, and number of comorbid medical conditions. Patients with PTSD reported more medical conditions than did other patients. Patients with PTSD currently in mental health treatment had worse health status than did those who reported no treatment; the health status of patients who reported past mental health treatment was generally comparable to that of those with no treatment. The prevalence and comorbidity of PTSD among this sample of VA ambulatory care patients were higher than previously reported among samples of community-residing adults. The association of PTSD with health status was substantial, suggesting that the burden of PTSD is at least comparable to, and may be worse than, that of depression. Mental health treatment alleviated some of this burden. The potential impact of PTSD on health status should be more widely recognized.

Validation of the Primary Care Alcohol Severity Measure

Alcohol-related disorders are common in primary care settings; many primary care physicians are ill-equipped to manage patients with alcohol-related disorders. The objective of this prospective cohort study was to develop and validate a patient-based measure, the Primary Care Alcohol Severity Measure, to determine which primary care patients with alcohol-related disorders would benefit from referral to alcohol treatment services. Four Boston-area Department of Veterans Affairs ambulatory care clinics were chosen as study sites. Two hundred seventy-eight male patients, mean age 55.5 years, 89.9% Caucasian, 42.5% married, all with CAGE Questionnaire scores greater than or equal to 2 and drinking within past year, participated in the study. We developed a multidimensional, 30-item measure that contained 2 subscales that assessed 2 symptom clusters of alcohol-related disorders: Physical and Behavioral. Each subscale's score was higher (more severe) for patients with a current Diagnostic and Statistical Manual of Mental Disorders, Third Edition, Revised diagnosis of alcohol dependence or abuse: P < .01 for the physical subscale and P < .0001 for the behavioral subscale. Patients with more physical symptoms had poorer physical and mental health status, whereas patients with more behavioral symptoms had poorer mental health status. Scores on the 2 subscales, along with age and history of prior treatment, predicted the use of alcohol treatment services in the following year: c = 0.90 in logistic regression. The Primary Care Alcohol Severity Measure is a valid measure of alcohol severity in primary care patients and predicts the use of alcohol treatment services. It is relatively brief and easy to use, requiring only standard medical history items and patient reports of behavioral symptoms. It may be a useful tool to improve the quality of care for primary care patients with alcohol-related disorders.

Racial/Ethnic Variations in Veterans’ Ambulatory Care Use

We assessed racial/ethnic variations in patterns of ambulatory care use among Department of Veterans Affairs (VA) health care-eligible veterans to determine if racial/ethnic differences in health care use persist in equal-access systems. We surveyed 3227 male veterans about their health and ambulatory care use. Thirty-eight percent of respondents had not had a health care visit in the previous 12 months. Black (odds ratio [OR] = 0.5), Hispanic (OR = 0.4), and Asian/Pacific Islander veterans (OR=0.4) were less likely than White veterans to report any ambulatory care use. Alternately, Whites (OR=2.2) were more likely than other groups to report ambulatory care use. Being White was a greater predictor of health care use than was having fair or poor health (OR=1.4) or functional limitations (OR=1.5). In non-VA settings, racial/ethnic minorities were less likely to have a usual provider of health care. There was no VA racial/ethnic variation in this parameter. Racial/ethnic disparities in health and health care use are present among VA health care-eligible veterans. Although the VA plays an important role in health care delivery to ethnic minority veterans, barriers to VA ambulatory care use and additional facilitators for reducing unmet need still need to be investigated.

Estimating the costs of VA ambulatory care.

This article reports how we matched Common Procedure Terminology (CPT) codes with Medicare payment rates and aggregate Veterans Affairs (VA) budget data to estimate the costs of every VA ambulatory encounter. Converting CPT codes to encounter-level costs was more complex than a simple match of Medicare reimbursements to CPT codes. About 40 percent of the CPT codes used in VA, representing about 20 percent of procedures, did not have a Medicare payment rate and required other cost estimates. Reconciling aggregated estimated costs to the VA budget allocations for outpatient care produced final VA cost estimates that were lower than projected Medicare reimbursements. The methods used to estimate costs for encounters could be replicated for other settings. They are potentially useful for any system that does not generate billing data, when CPT codes are simpler to collect than billing data, or when there is a need to standardize cost estimates across data sources.

Overweight, Obesity, and Associated Disease Burden in the Veterans Affairs Ambulatory Care Population

This report describes the prevalence of overweight and obesity and estimates the disease burden associated with excess weight in ambulatory Veterans Affairs (VA) patients. Height and weight were measured, and self-reported age and self-reported morbidities were obtained for 1,731 patients. Prevalence odds ratios explain the association of self-reported disease on increasing weight status category using body mass index. Seventy-five percent of the participants were overweight or obese. Obesity was significantly higher in the younger patients. Graded increases in odds ratios were observed with increasing severity of overweight and obesity for all morbidities, except heart disease. Overweight, obesity, and associated disease burden are prevalent in the VA health care system, particularly in younger VA patients, which may contribute to the higher prevalence of certain morbidities observed in VA populations compared with private sector outpatients. Department of Veterans Affairs should emphasize obesity prevention and treatment during the design and implementation of ambulatory care services.

Racial Variations in Department of Veterans Affairs Ambulatory Care Use and Unmet Health Care Needs

Our objective was to describe racial/ethnic variations in Department of Veterans Affairs (VA) ambulatory care use and its association with the presence of unmet health care needs. Using the 1992 National Survey of Veterans, we examined race/ethnicity and unmet health care need for ambulatory care users of VA and non-VA facilities. Black and Hispanic veterans were more likely to report any VA use. In unadjusted analyses, American Indian/Eskimo, Hispanic, and black veterans were 4.4, 2.5, and 1.9 times more likely, respectively, than white veterans to report an inability to get needed care. Adjusting for VA ambulatory care use diminished the disparity in inability to get needed care between American Indian/Eskimo or Hispanic veterans and white veterans and eliminated the disparity between black and white veterans. Our findings support the VA's role as a medical safety net provider and suggest that VA ambulatory care use is effective in mitigating health-related racial disparities for some veterans. Additional facilitators for reducing unmet need should be explored.

Decision-making preference and opportunity in VA ambulatory care patients: association with patient satisfaction.

Using data from the Veterans Health Study, associations were examined for decision-making preference, decision-making opportunity, and satisfaction with medical care among a sample of 266 men who use Department of Veterans Affairs (VA) ambulatory health care services. Results indicated that veterans with a high preference for involvement in decision-making and low provider-offered decision-making opportunities had significantly lower satisfaction with medical care compared to veterans with either low preference for decision-making involvement with high or low opportunity, or those with a high decision-making preference and high decision-making opportunity. The findings suggest that health care providers may increase patient satisfaction with medical care by providing opportunities for decision-making to patients who prefer involvement in their health care decision-making. Provider strategies for increasing patient decision-making involvement are discussed.

The Veterans Affairs medical care system: hospital and clinic utilization statistics for 1994.

The authors describe the role the Veterans Affairs (VA) medical system plays as a provider of clinic and hospital services by examining utilization levels and users' characteristics. The Veterans Affairs hospital discharge database, the Veterans Affairs outpatient clinic files, and the veteran population files were used to estimate the number of persons using the Veterans Affairs medical care system in 1994 and the intensity of their clinic and hospital use. Demographic and clinical characteristics of users were tabulated. In 1994, 2.7 million veterans, 10.3% of all US veterans, and approximately 23% of veterans who would have met the statutory eligibility requirements for Veterans Affairs care, used the hospital and/or clinic components of the Veterans Affairs medical system. Sixty-three percent of the system's users were younger than age 65, and 10.5% were women. These 2.7 million veterans had 901,665 Veterans Affairs hospital stays, 15.5 million bed-days, and 31.2 million outpatient visits in fiscal year 1994. The average number of hospitalizations per hospital user was 1.71; the average number of visits per clinic user was 11.7. Medical, surgical, and psychiatric diagnosis-related groups (DRGs) accounted for 56%, 21%, and 23%, respectively, of hospitalizations, but psychiatric diagnosis-related groups accounted for 43% of all inpatient days. Principal medicine clinic visits and psychiatry clinic visits accounted for 21% and 16% of Veterans Affairs ambulatory care. Because the patient population served by the Veterans Affairs system is skewed in a number of ways, its contribution as a provider of health services in the United States varies by gender, age, socioeconomic status, and diagnosis.

Restructuring VA ambulatory care and medical education: the PACE model of primary care.

The Veterans Health Administration (VHA) Western Region and associated medical schools formulated a set of recommendations for an improved ambulatory health care delivery system during a 1988 strategic planning conference. As a result, the Department of Veterans Affairs (VA) Medical Center in Sepulveda, California, initiated the Pilot (now Primary) Ambulatory Care and Education (PACE) program in 1990 to implement and evaluate a model program. The PACE program represents a significant departure from traditional VA and non-VA academic medical center care, shifting the focus of care from the inpatient to the outpatient setting. From its inception, the PACE program has used an interdisciplinary team approach with three independent global care firms. Each firm is interdisciplinary in composition, with a matrix management structure that expands role function and empowers team members. Emphasis is on managed primary care, stressing a biopsychosocial approach and cost-effective comprehensive care emphasizing prevention and health maintenance. Information management is provided through a network of personal computers that serve as a front end to the VHA Decentralized Hospital Computer Program (DHCP) mainframe. In addition to providing comprehensive and cost-effective care, the PACE program educates trainees in all health care disciplines, conducts research, and disseminates information about important procedures and outcomes. Undergraduate and graduate trainees from 11 health care disciplines rotate through the PACE program to learn an integrated approach to managed ambulatory care delivery. All trainees are involved in a problem-based approach to learning that emphasizes shared training experiences among health care disciplines. This paper describes the transitional phases of the PACE program (strategic planning, reorganization, and quality improvement) that are relevant for other institutions that are shifting to training programs emphasizing primary and ambulatory care.

Present Activities of 1989 U.S. Medical Graduates

New forms of health care delivery and reimbursement trends have increased interest in the ambulatory care setting as a site for medical student education. It is estimated that from 50% to 60% of all medical students receive some portion of their medical training in a Department of Veterans Affairs (VA) facility. However, only about 5% of the total student ambulatory care educational experience is taking place at VA facilities. The problems in implementing and maintaining ambulatory care teaching programs for medical students encompass a variety of areas, such as lack of faculty incentive, time, expertise, and commitment; student resistance to training in this less attractive arena, and economic obstacles. Medical schools and VA medical centers will have to work in a mutually supportive relationship to develop joint goals and objectives for medical student teaching. Commitment of resources is essential, as is the need to reward ambulatory teaching through academic advancement and salary incentives. Faculty recruitment and development will be necessary, and research to identify the most successful of the VA ambulatory care teaching settings should be undertaken. The time has come for improved medical student education in VA ambulatory care settings, and there is now a need for collaborative planning between the medical schools and the VA.
