Introducing clinical pharmacy specialists into interprofessional primary care teams: Assessing pharmacists' team integration and access to care for rural patients.

ABSTRACT: Clinical pharmacy specialists (CPS) were deployed nationally to improve care access and relieve provider burden in primary care.The aim of this study was to assess CPS integration in primary care and the Clinical Pharmacy Specialist Rural Veteran Access (CRVA) initiative's effectiveness in improving access.Concurrent embedded mixed-methods evaluation of participating CRVA CPS and their clinical team members (primary care providers, others).Health care providers on primary care teams in Veterans Health Administration (VHA).Perceived CPS integration in comprehensive medication management assessed using the MUPM and semi-structured interviews, and access measured with patient encounter data.There were 496,323 medical encounters with CPS in primary care over a 3-year period. One hundred twenty-four CPS and 1177 other clinical team members responded to a self-administered web-based questionnaire, with semi-structured interviews completed by 22 CPS and clinicians. Survey results indicated that all clinical provider groups rank CPS as making major contributions to CMM. CPS ranked themselves as contributing more to CMM than did their physician team members. CPS reported higher job satisfaction, less burn out, and better role fit; but CPS gave lower scores for communication and decision making as clinic organizational attributes. Themes in provider interviews focused on value of CPS in teams, relieving provider burden, facilitators to integration, and team communication issues.This evaluation indicates good integration of CPS on primary care teams as perceived by other team members despite some communication and role clarification challenges. CPS may play an important role in improving access to primary care.

Access to Lung Cancer Screening in the Veterans Health Administration: Does Geographic Distribution Match Need in the Population?

BACKGROUND: Studies show uneven access to Medicare-approved lung cancer screening (LCS) programs across the United States. The Veterans Health Administration (VA), the largest national US integrated health system, is potentially well positioned to coordinate LCS services across regional units to ensure that access matches distribution of need nationally. RESEARCH QUESTION: To what extent does LCS access (considering both VA and partner sites) and use match the distribution of eligible Veterans at state and regional levels? METHODS: In this retrospective analysis, we identified LCS examinations in VA facilities between 2013 and 2019 from the VA Corporate Data Warehouse and plotted VA facilities with LCS geographically. We compared estimated LCS rates (unique Veterans screened per LCS-eligible population) across states and VA regional units. Finally, we assessed whether the VA's new partnership with the GO2 Foundation for Lung Cancer (which includes more than 750 LCS centers) closes geographic gaps in LCS access. RESULTS: We identified 71,898 LCS examinations in 96 of 139 (69.1%) VA facilities in 44 states between 2013 and 2019, with substantial variation across states (0-8 VA LCS facilities per state). Screening rates among eligible Veterans in the population varied more than 30-fold across regional networks (rate ratio, 33.6; 95% CI, 30.8-36.7 for VA New England vs Veterans Integrated Service Network 4), with weak correlation between eligible populations and LCS rates (coefficient, -0.30). Partnering with the GO2 Foundation for Lung Cancer expands capacity and access (eg, all states now have ≥ 1 VA or partner LCS site), but 9 of the 12 states with the highest proportions of rural Veterans still have ≤ 3 total LCS facilities. INTERPRETATION: Disparities in LCS access exist based on where Veterans live, particularly for rural Veterans, even after partnering with the GO2 Foundation for Lung Cancer. The nationally integrated VA system has an opportunity to leverage regional resources to distribute and coordinate LCS services better to ensure equitable access.

Confirmation Bias as a Factor in Pharmacy Student Assessment of Research Study Quality.

Objective. To determine whether pharmacy students' prior beliefs and attitudes about drug products and dietary supplements affected their ability to analyze the quality of research study abstracts and use them in making drug recommendations to patients. Methods. Fifty-nine Doctor of Pharmacy (PharmD) students in a drug literature course were randomly assigned to receive one of two forms to evaluate four drug literature abstracts of varying quality and study design. On each form, there were two abstracts that had been taken directly from published research studies and two abstracts in which a different product had been substituted for the actual product studied. Pharmacy students completed a questionnaire about the studies to determine whether their evaluation of quality was affected by their prior opinions about the products. Results. Students correctly recognized the relative quality of the studies. However, after reading abstracts of research articles that were identical except for the product named, students were still more likely to recommend drugs approved by the Food and Drug Administration than dietary supplements. Conclusion. Pharmacy students' evaluation of clinical research studies was mildly influenced by confirmation bias but more so by the quality of the research.

Systems change to improve tobacco use identification and referral in the chiropractic setting: a pilot study.

Background: Tobacco use remains a leading cause of death and disability in the United States. Health professionals need to address the use of tobacco products by their patients, but chiropractic clinical systems often remain unsupported and underappreciated in their role to facilitate tobacco use cessation. Methods: This pilot study tested an intervention to assist a chiropractic community to implement sustainable health systems changes for tobacco use based on U.S. Public Health Service guidelines. Chiropractors were educated on the Ask, Advise, Refer (AAR) approach, provided with ongoing guidance, and followed for six months to assess systems change. The study was conducted from March 2016 to July 2017. Results: Evidence of a systematic process in place to conduct AAR was present in all clinics by the end of the fourth month of the intervention period. Although no clinic had sustained health system change for full AAR, all six of the clinics made progress in the individual AAR components. Furthermore, five clinics achieved sustained system change for the Ask component, as after systems change was achieved, the rate of tobacco user identifications did not drop below 50%. For the Advise component, five clinics succeeded in having individual months of ≥50% of tobacco users being advised, and three clinics achieved the formal definition of systems change. For the Refer component, no clinic achieved system change, although four had individual months of ≥50% of tobacco users being referred. The patient quit rate was 13.3% (n = 15) for the 30-day follow-up and 16.7% (n = 6) for the three-month follow-up. Conclusions: This study demonstrates the feasibility of implementing a health systems change in the chiropractic setting to identify tobacco users, to advise them to quit, and to refer users for cessation services.

Development and Validation of a Tool to Identify Patients With Type 2 Diabetes at High Risk of Hypoglycemia-Related Emergency Department or Hospital Use.

Importance: Hypoglycemia-related emergency department (ED) or hospital use among patients with type 2 diabetes (T2D) is clinically significant and possibly preventable. Objective: To develop and validate a tool to categorize risk of hypoglycemic-related utilization in patients with T2D. Design, Setting, and Participants: Using recursive partitioning with a split-sample design, we created a classification tree based on potential predictors of hypoglycemia-related ED or hospital use. The resulting model was transcribed into a tool for practical application and tested in 1 internal and 2 fully independent, external samples. Development and internal testing was conducted in a split sample of 206 435 patients with T2D from Kaiser Permanente Northern California (KPNC), an integrated health care system. The tool was externally tested in 1 335 966 Veterans Health Administration and 14 972 Group Health Cooperative patients with T2D. Exposures: Based on a literature review, we identified 156 candidate predictor variables (prebaseline exposures) using data collected from electronic medical records. Main Outcomes and Measures: Hypoglycemia-related ED or hospital use during 12 months of follow-up. Results: The derivation sample (n = 165 148) had a mean (SD) age of 63.9 (13.0) years and included 78 576 (47.6%) women. The crude annual rate of at least 1 hypoglycemia-related ED or hospital encounter in the KPNC derivation sample was 0.49%. The resulting hypoglycemia risk stratification tool required 6 patient-specific inputs: number of prior episodes of hypoglycemia-related utilization, insulin use, sulfonylurea use, prior year ED use, chronic kidney disease stage, and age. We categorized the predicted 12-month risk of any hypoglycemia-related utilization as high (>5%), intermediate (1%-5%), or low (<1%). In the internal validation sample, 2.0%, 10.7%, and 87.3% were categorized as high, intermediate, and low risk, respectively, with observed 12-month hypoglycemia-related utilization rates of 6.7%, 1.4%, and 0.2%, respectively. There was good discrimination in the internal validation KPNC sample (C statistic = 0.83) and both external validation samples (Veterans Health Administration: C statistic = 0.81; Group Health Cooperative: C statistic = 0.79). Conclusions and Relevance: This hypoglycemia risk stratification tool categorizes the 12-month risk of hypoglycemia-related utilization in patients with T2D using only 6 inputs. This tool could facilitate targeted population management interventions, potentially reducing hypoglycemia risk and improving patient safety and quality of life.

Adoption of a new technology in a Veterans Affairs national formulary system with local implementation: the insulin glargine example.

A study group gathered by the Pharmacy & Therapeutics Society reviewed data on the Department of Veterans Affairs (VA) health care system's implementation of a new technology (insulin glargine) for patients with diabetes. It examined local implementation of VA criteria for nonformulary use of insulin glargine in 21 VA treatment facilities that were surveyed about the issue. The examination found differences in the use of insulin glargine across the 21 treatment facilities and in the approach to implementing the criteria for nonformulary use of insulin glargine used at the individual VA treatment facility level. Differences were identified regarding the respective roles of endocrinologists and PCPs in prescribing insulins, including insulin glargine. The study group urges further short- and long-term research to better understand the utilization, cost, and health outcome implications of the implementation process for the nonformulary criteria. Lessons learned from such research could benefit other health care systems and formulary committees.

Utilization of medical services by Veterans Health Study (VHS) respondents.

The first objective of this study was to profile Veterans Health Study (VHS) respondents' use of medical services-the types of services used, use of a regular source of care, and the propensity to use services for selected symptoms. We focused on differential use of VA and non-VA services and highlighted differences in use by age group. The second objective was to use multivariate analysis to identify factors associated with respondents' use of any medical services and with VA services specifically. We incorporated 2 self-reported variables not used in previous studies of VA utilization-health status and disease burden. Patients receiving ambulatory care services in 4 VA ambulatory outpatient clinics in the greater Boston area were eligible for inclusion in the VHS. A sample of 2425 community-dwelling male veterans was randomly selected from among veterans receiving ambulatory services at Boston-area VA facilities. This analysis focuses on 1909 respondents for whom we had complete data. Interviews and questionnaires were used to collect cross-sectional, observational data on sociodemographic, economic, and clinical characteristics; health status; disease burden; and service-connected disability (SCD) rating. To measure health status, we used 2 summary measures, the Physical Component Summary (PCS) and the Mental Component Summary (MCS), derived from the 8 scales of the Medical Outcomes Study Short Form 36-item Health Survey (MOS SF-36). To measure disease burden, we used the Physical Comorbidity Index (PHYCI) and Mental Comorbidity Index (MENCI), composed of 30 physical and 6 mental health conditions and symptoms, respectively. Information on the availability of non-VA insurance was obtained from administrative VA files. Information on utilization prior to the interview was self-reported. Recall periods of 3 and 12 months were used for ambulatory and inpatient services, respectively. We used descriptive statistics to profile respondents and their utilization patterns. We used multivariate probit models to identify respondent characteristics associated with use of any medical services, medical visits, mental health visits, and hospital stays. Independent variables used in the models were socioeconomic and demographic characteristics, and measures of disease burden, health status, and VA eligibility. The respondents relied heavily on the VA for medical care: 74% of the respondents said the VA was their regular source of care; 72% of all the respondents and 87% of those who had used any medical service in the recall period had used a VA service; 68% of those who were hospitalized used a VA hospital; and 76% of the medical care the respondents received and 60% of their hospital stays were in VA facilities. Younger veterans (aged 22-44) used substantially more mental health services than older respondents, but they were less likely than older veterans to have seen a doctor recently for most of the medical symptoms studied. PHYCI and PCS were significantly related to use of any medical services and to use of inpatient services; MENCI and MCS were significantly related to use of mental health services (P<.05 for each, respectively). Lower income and lack of alternatives to VA care were directly related to use of any VA services and VA inpatient services. Information on the reasons for differential use of VA and non-VA services can be useful to the VA as it serves an aging veteran population, seeks to provide comprehensive care to a wider spectrum of veterans, and moves into a more competitive healthcare marketplace.

Patient-reported measures of health: The Veterans Health Study.

The goal of the Veterans Health Study (VHS) was to extend the work of the Medical Outcomes Study (MOS) into the VA, by developing methodology for monitoring patient-based outcomes of care for use in ambulatory outpatient care. The principal objective of the VHS was developing valid and reliable measures to assess general health-related quality of life (HRQoL) and identifying the presence of selected health conditions, their severity, and their impact on HRQoL. In this article, we provide an overview of the historical context, framework, objectives, and applications of the VHS for the purpose of assessing the health outcomes of veteran patients. The VHS is a prospective observational study that has followed 2425 VA patients for up to 2 years. The patients were sampled from users of the Veterans Affairs (VA) ambulatory care system in the Boston area. The health conditions selected were hypertension, diabetes, chronic lung disease, osteoarthritis of the knee, chronic low-back pain, and alcohol-related problems. These conditions were chosen because they are both prevalent in the VA and have measurable impacts on HRQoL. One of the cornerstones of the VHS was the development of the Veterans SF-36, modified from the MOS SF-36 for use in veteran ambulatory populations. Other key accomplishments included the development of patient-based disease-specific measures of health and the establishment of methods and logistics for comprehensive health outcomes research in large health care systems such as the VA, using these patient-based measures. Selected measures developed in the VHS, eg, the Veterans SF-36, have been integrated into the VA outcomes measurement system. The scope of the VHS is unique; it resulted in the development of a broad range of patient-focused process and outcome measures, as well as methodologies for assessing large numbers of patients, that have been widely used in the VA outpatient health care system for monitoring health outcomes across the nation.

Measuring the quality of depression care in a large integrated health system.

BACKGROUND: Guideline-based depression process measures provide a powerful way to monitor depression care and target areas needing improvement. OBJECTIVES: To assess the adequacy of depression care in the Veterans Health Administration (VHA) using guideline-based process measures derived from administrative and centralized pharmacy records, and to identify patient and provider characteristics associated with adequate depression care. RESEARCH DESIGN: This is a cohort study of patients from 14 VHA hospitals in the Northeastern United States which relied on existing databases. Subject eligibility criteria: at least one depression diagnosis during 1999, neither schizophrenia nor bipolar disease, and at least one antidepressant prescribed in the VHA during the period of depression care profiling (June 1, 1999 through August 31, 1999). Depression care was evaluated with process measures defined from the 1997 VHA depression guidelines: antidepressant dosage and duration adequacy. We used multivariable regression to identify patient and provider characteristics predicting adequate care. SUBJECTS: There were 12,678 patients eligible for depression care profiling. RESULTS: Adequate dosage was identified in 90%; 45% of patients had adequate duration of antidepressants. Significant patient and provider characteristics predicting inadequate depression care were younger age (<65), black race, and treatment exclusively in primary care. CONCLUSIONS: Under-treatment of depression exists in the VHA, despite considerable mental health access and generous pharmacy benefits. Certain patient populations may be at higher risk for inadequate depression care. More work is needed to align current practice with best-practice guidelines and to identify optimal ways of using available data sources to monitor depression care quality.

Sunburn reduction through parental role modeling and sunscreen vigilance.

OBJECTIVES: To identify characteristics associated with child sunburn experience and sun protection practices, including parent and child demographics, phenotype, and sun-related knowledge, attitudes, and behaviors. STUDY DESIGN: A nationally representative telephone survey conducted in 1999 with 651 parents of children 5 to 12 years of age to collect data relating to the sun-related knowledge, attitudes, and behaviors of the parent and child. RESULTS: Nearly half of parents (49%) and children (44%) were sunburnt during the previous summer. Parents who reported that they had been sunburnt were more likely to have children who had been sunburnt (OR = 2.9, 95% CI = 2.0, 4.2). Conversely, parents with a high level of sun protection behavior were less likely to report being sunburnt (OR = 0.6, 95% CI = 0.4, 0.9), and their children were more likely to have a high level of sun protection behavior (OR = 3.0, 95% CI = 2.0, 4.6) and sunscreen vigilance (OR = 2.7, 95% CI = 1.7, 4.5). High sunscreen vigilance was associated with a 60% reduction in child sunburning. CONCLUSIONS: The sunburn experience and sun protection practices of children (5-12 years of age) are closely linked to a number of modifiable attitudes and behaviors of their parents. Therefore the inclusion of parents and care givers in interventions targeting children may increase program efficacy.
