Association of Serious Hypoglycemic Events in Older Adults With Changes in Glycemic Performance Measures.

BACKGROUND: Reducing serious hypoglycemic events is a Federal-wide objective. Despite studies of trends for rates of serious hypoglycemia in existing literature, rigorous evaluation of links between the observed trends and changes in professional guidelines or performance measures for glycemic control is lacking. OBJECTIVE: To evaluate whether changes in professional society guidelines and performance measures for glycemic control correspond to changes in rates of serous hypoglycemia. RESEARCH DESIGN: This was a retrospective observational study. We merged Veterans Health Administration (VHA) and Medicare patient-level databases of VHA patients and identified those aged 65 years and above and receiving hypoglycemic agents. We derived age-adjusted and sex-adjusted annual rates and constructed piecewise Poisson regression models adjusting for age and sex to assess time trends of the rates. SUBJECTS: VHA patients, 2002-2015. MEASURES: The main outcome was the annual rates (2004-2015) of serious hypoglycemia, defined as hypoglycemia-related emergency department visits or hospitalizations. Secondary outcomes were annual rates of hemoglobin (Hb) A1c level <7% and >9%. Age and sex were additional variables. RESULTS: The annual rate for hypoglycemia decreased by 4.8% (rate ratio: 0.952; 95% confidence interval, 0.949-0.956) for 2008-2015 but did not change (1.001; 0.994-1.001) in 2004-2008. In 2008-2015, the annual rate for HbA1c <7% decreased by 5.0% (0.950; 0.949-0.951) but for HbA1c >9%, increased by 7.9% (1.079; 1.076-1.082). CONCLUSION: The cooccurrence of decreasing rates for HbA1c<7% and serious hypoglycemia since 2008 supports the possibility that withdrawal of a <7% HbA1c measure in 2008 impacted clinical practice and patient outcomes.

The interprofessional VA quality scholars program: Promoting predoctoral nursing scientists and their career trajectories.

BACKGROUND: The VA Quality Scholars (VAQS) program is an interprofessional fellowship that provides a unique opportunity for predoctoral nurse scientists to embed their work in quality improvement learning "laboratories" to inform their scholarship, science, and research. PURPOSE: To describe the VAQS program in relation to promoting nursing science and predoctoral nurse scientist (PhD) career trajectories, and to propose policy implications. METHOD: Data were collected on all predoctoral (PhD, DNP) nurses who entered and completed the VAQS program nationally. FINDINGS: A total of 17 predoctoral nurses (11 PhD and 6 DNP) have completed the VAQS program. Ten predoctoral PhD nurses (91%) completed their degree while in the program. Nine predoctoral PhD nurses (82%) entered a postdoctoral fellowship, and many obtained positions as faculty at research-intensive universities postfellowship. DISCUSSION: The knowledge, skills, and experiences gained by predoctoral nurse scientists from the VAQS's program contribute to their nursing research and professional career growth.

A Qualitative Evaluation of the Pain Management VA-ECHO Program Using the RE-AIM Framework: The Participant's Perspective.

Introduction: Veterans frequently seek chronic pain care from their primary care providers (PCPs) who may not be adequately trained to provide pain management. To address this issue the Veterans Health Administration (VHA) Office of Specialty Care adopted the Specialty Care Access Network Extension for Community Healthcare Outcomes (VA-ECHO née SCAN-ECHO). The VA-ECHO program offered training and mentoring by specialists to PCPs and their staff. VA-ECHO included virtual sessions where expertise was shared in two formats: (1) didactics on common pain conditions, relevant psychological disorders, and treatment options and (2) real-time consultation on patient cases. Materials and methods: VA-ECHO participants' perspectives were obtained using a semi-structured interview guide designed to elicit responses based on the RE-AIM (reach, effectiveness, adoption, implementation, and maintenance) framework. A convenience sampling was used to recruit PCPs and non-physician support staff participants. Non-physicians from rural VHA sites were purposively sampled to gain diverse perspectives. Findings: This qualitative study yielded data on each RE-AIM domain except reach. Program reach was not measured as it is outside the scope of this study. Respondents reported program effectiveness as gains in knowledge and skills to improve pain care delivery. Effective incorporation of learning into practice was reflected in respondents' perceptions of improvements in: patient engagement, evidenced-based approaches, appropriate referrals, and opioid use. Program adoption included how participating health care systems selected trainees from a range of sites and roles to achieve a wide reach of pain expertise. Participation was limited by time to attend and facilitated by institutional support. Differences and similarities were noted in implementation between hub sites. Maintenance was revealed when respondents noted the importance of the lasting relationships formed between fellow participants. Discussion: This study highlights VA-ECHO program attributes and unintended consequences. These findings are expected to inform future use of VA-ECHO as a means to establish a supportive consultation network between primary and specialty care providers to promote the delivery evidence-based pain management practices.

The assessment and management of quality of life of older adults with diabetes mellitus.

Introduction: As the population ages, the number of older adults with diabetes mellitus will continue to rise. The burden of diabetes on older adults is significant due to the disease itself, its complications, and its treatments. This is compounded by geriatric syndromes such as frailty and cognitive dysfunction. Consequently, health and diabetes-related quality of life (QoL) are diminished.Areas covered: This article reviews the value of assessing QoL in providing patient-centered care and the associations between QoL measures and health outcomes. The determinants of QoL particular to diabetes and the older population are reviewed, including psychosocial, physical, and cognitive burdens of diabetes and aging and the impact of hypoglycemia on QoL. Strategies are described to alleviate these burdens and improve QoL, and barriers to multidisciplinary patient-centered care are discussed. QoL measurement instruments are reviewed.Expert opinion: The goals of treating diabetes and its complications should be considered carefully along with each patient's capacity to withstand the burdens of treatment. This capacity is reduced by socioeconomic, psychological, cognitive, and physical factors reduces this capacity. Incorporating measurement of HRQoL into clinical practices is possible, but deficiencies in the systems of health-care delivery need to be addressed to facilitate their use.

Racial differences in trends of serious hypoglycemia among higher risk older adults in US Veterans Health Administration, 2004-2015: Relationship to comorbid conditions, insulin use, and hemoglobin A1c level.

AIMS: To evaluate temporal trends in racial/ethnic groups in rates of serious hypoglycemia among higher risk patients dually enrolled in Veterans Health Administration and Medicare fee-for-service and assess the relationship(s) between hypoglycemia rates, insulin/secretagogues and comorbid conditions. METHODS: Retrospective observational serial cross-sectional design. Patients were ≥65 years receiving insulin and/or secretagogues. The primary outcome was the annual (period prevalence) rates (2004-2015), per 1000 patient years, of serious hypoglycemic events, defined as hypoglycemic-related emergency department visits or hospitalizations. RESULTS: Subjects were 77-83% White, 7-10% Black, 4-5% Hispanic, <2% women; 38-58% were ≥75 years old; 72-75% had ≥1 comorbidity. In 2004-2015, rates declined from 63.2 to 33.6(-46.9%) in Blacks; 29.7 to 20.3 (-31.6%) in Whites; and 41.8 to 29.6 (-29.3%) in Hispanics. The Black-White rate differences narrowed regardless of insulin use, hemoglobin A1c level, and frequency and various combinations of comorbid conditions. Among insulin users, the Black-White contrast decreased from 34.7 (98.5 vs. 63.8) in 2004 to 13.2 (43.6 vs. 30.4) in 2015; in non-insulin users, the contrast was 25.7 (44.1 vs. 18.4) in 2004 and 10.1 (18.9 vs. 8.8) in 2015. CONCLUSION: Marked declines in serious hypoglycemia events occurred across race, medications, and comorbidities, suggesting significant changes in clinical practice.

Defining and measuring population health quality of outpatient diabetes care in Israel: lessons from the quality indicators in community health program.

In Israel, as in other Organization for Economic Co-operation and Development countries, performance measurement is a key public health strategy in monitoring and improving population health outcomes. The Israeli Quality Indicators in Community Healthcare (QICH) program has utilized electronic health records to monitor ambulatory care for the entire Israeli population since 2002. In 2006 the measures were updated to include laboratory values. They have been subsequently revised by stratifying by age, duration, adding medications, and changing frequency of testing for certain process measures. However, the QICH glycemic control measures do not address co-morbid conditions either thru exclusion criteria or higher target ranges. They also do not address potential over treatment in patients with complex medication conditions.In the United States there have also been changes in nationally endorsed diabetes specific performance measures since 2007. However, there have also been public disagreements among United States professional societies, government agencies, and performance measurement organizations as to whether the current glycemic dichotomous ("all or none") threshold measures, without exclusion criteria, are consistent with the most recent evidence. Specifically, most guidelines now recommend individualized target goals based upon co-morbid conditions, risk of harms from medications, and patient preferences.Concerns have been raised that the current glycemic performance measures have resulted in inappropriate care, such as medication over-treatment, and serious harms, such as hypoglycemia, especially in older adults. There currently are no national surveillance systems or measures that monitor these untoward outcomes.We recommend several actions that QICH could consider to advance diabetes specific performance measurement science and population health: Convene an international conference; implement technical modifications of current measures and surveillance systems; and, most importantly, acknowledge patient autonomy by developing measures that document individualization of target values using shared decision making.

Evaluation of a national telemedicine initiative in the Veterans Health Administration: Factors associated with successful implementation.

Background The Consolidated Framework for Implementation Research was used to evaluate implementation facilitators and barriers of Specialty Care Access Network-Extension for Community Healthcare Outcomes (SCAN-ECHO) within the Veterans Health Administration. SCAN-ECHO is a video teleconferencing-based programme where specialist teams train and mentor remotely-located primary care providers in providing routine speciality care for common chronic illnesses. The goal of SCAN-ECHO was to improve access to speciality care for Veterans. The aim of this study was to provide guidance and support for the implementation and spread of SCAN-ECHO. Methods Semi-structured telephone interviews with 55 key informants (primary care providers, specialists and support staff) were conducted post-implementation with nine sites and analysed using Consolidated Framework for Implementation Research constructs. Data were analysed to distinguish sites based on level of implementation measured by the numbers of SCAN-ECHO sessions. Surveys with all SCAN-ECHO sites further explored implementation information. Results Analysis of the interviews revealed three of 14 Consolidated Framework for Implementation Research constructs that distinguished between low and high implementation sites: design quality and packaging; compatibility; and reflecting and evaluating. The survey data generally supported these findings, while also revealing a fourth distinguishing construct - leadership engagement. All sites expressed positive attitudes toward SCAN-ECHO, despite struggling with the complexity of programme implementation. Conclusions Recommendations based on the findings include: (a) expend more effort in developing and distributing educational materials; (b) restructure the delivery process to improve programme compatibility;

A Health Assessment Survey of Veteran Students: Utilizing a Community College-Veterans Affairs Medical Center Partnership.

OBJECTIVE: To assess health status among student veterans at a community college utilizing a partnership between a Veterans Affairs Medical Center and a community college. PARTICIPANTS: Student veterans at Cuyahoga Community College in Cleveland, Ohio, in January to April 2013. METHODS: A health assessment survey was sent to 978 veteran students. Descriptive analyses to assess prevalence of clinical diagnoses and health behaviors were performed. Logistic regression analyses were performed to assess for independent predictors of functional limitations. RESULTS: 204 students participated in the survey (21% response rate). Self-reported depression and unhealthy behaviors were high. Physical and emotional limitations (45% and 35%, respectively), and pain interfering with work (42%) were reported. Logistic regression analyses confirmed the independent association of self-reported depression with functional limitation (odds ratio [OR] = 3.3, 95% confidence interval [CI] 1.4-7.8, p < 0.05, and C statistic 0.72) and of post-traumatic stress disorder with pain interfering with work (OR 3.9, CI 1.1-13.6, p < 0.05, and C statistic 0.75). CONCLUSION: A health assessment survey identified priority areas to inform targeted health promotion for student veterans at a community college. A partnership between a Veterans Affairs Medical Center and a community college can be utilized to help understand the health needs of veteran students.

Understanding the Health Needs and Barriers to Seeking Health Care of Veteran Students in the Community.

OBJECTIVES: Access to care at Veterans Affairs facilities may be limited by long wait times; however, additional barriers may prevent US military veterans from seeking help at all. We sought to understand the health needs of veterans in the community to identify possible barriers to health-seeking behavior. METHODS: Focus groups were conducted with veteran students at a community college until thematic saturation was reached. Qualitative data analysis involved both an inductive content analysis approach and deductive elements. RESULTS: A total of 17 veteran students participated in 6 separate focus groups. Health needs affecting health-seeking behavior were identified. Themes included lack of motivation to improve health, concern about social exclusion and stigma, social interactions and behavior, limited access to affordable and convenient health care, unmet basic needs for self and family, and academics competing with health needs. CONCLUSIONS: Veterans face a range of personal, societal, and logistical barriers to accessing care. In addition to decreasing wait times for appointments, efforts to improve the transition to civilian life; reduce stigma; and offer assistance related to work, housing, and convenient access to health care may improve health in veteran students.

De-implementation of inappropriately tight control (of hypoglycemia) for health: protocol with an example of a research grant application.

BACKGROUND: Implementation of practice change is difficult and large scale implementation is particularly difficult. Among the challenges facing the healthcare system in general and healthcare organizations is the overuse of low value care. Improving medication safety also constitutes an attempt to reduce low value or potentially harmful care. Critical issues of overuse of low value practices and medication safety intersect in overtreatment of diabetes. Specifically, (over)intensive glycemic control increases hypoglycemia risk and morbidity without providing meaningful benefit. Our work indicates that among patients with diabetes who are at high risk for hypoglycemia, potential overtreatment is common. The Choosing Wisely Initiative to reduce low value care led by the American Board of Internal Medicine Foundation recommends not to treat most persons over 65 years of age with medications to reduce the A1c<7.5%. For most physicians this involves a change in practice. We will study the implementation of the Veterans Health Administration's Choosing Wisely Initiative (which includes hypoglycemic safety as a targeted condition) with three specific aims: (1) to assess the overall impact, both intended and unintended, of the Choosing Wisely Initiative to reduce overtreatment of diabetes in especially vulnerable populations; (2) to assess the impact of commitment to quality, teaching intensity, and safety culture on likelihood of overtreatment; and (3) to identify configurations of the implementation strategy, provider characteristics and organizational level factors that are associated with successful reduction of overtreatment rates by comparing high and low performers. Because focus on this initiative could have the unintended consequence of paying less attention to poor glycemic control (A1c>9%), we will also assess undertreatment. METHODS/DESIGN: We will take advantage of a natural experiment and use a Type III Hybrid Design that focuses on study of implementation while at the same time observing and gathering information on clinical interventions and outcomes. This mixed methods study will use longitudinal data and qualitative methods including Qualitative Comparative Analyses. DISCUSSION: Our multi-paradigm approach to examining potential mechanisms to explain the variation in reduction of rates of overtreatment will contribute to a better understanding of implementation of national dissemination projects and multi-component interventions in complex systems.

Providing specialty consultant expertise to primary care: an expanding spectrum of modalities.

In most models of health care delivery, the bulk of services are provided in primary care and there is frequent request for the input of specialty consultants. A critical issue for current and future health care systems is the effective and efficient delivery of specialist expertise for clinicians and patients. Input on a patient's care from specialty consultants usually requires a face-to-face visit between the patient and the consultant. New and complementary models of knowledge sharing have emerged. We describe a framework assessment of a spectrum of knowledge-sharing methods in the context of a patient-centered medical home. This framework is based on our experience in the Veterans Health Administration and a purposive review of the literature. These newer modes of specialty consultation include electronic consultation, secure text messaging, telemedicine of various types, and population preemptive consults. In addition to describing these modes of consultation, our framework points to several important areas in which further research is needed to optimize effectiveness.

Hidden complexities in assessment of glycemic outcomes: are quality rankings aligned with treatment?

OBJECTIVE: To evaluate facility rankings in achieving <7% A1C levels based on the complexity of glycemic treatment regimens using threshold and continuous measures. RESEARCH DESIGN AND METHODS: We conducted a retrospective administrative data analysis of Veterans Health Administration Medical Centers in 2003-2004. Eligible patients were identified using National Committee for Quality Assurance (NCQA) measure specifications. A complex glycemic regimen (CGR) was defined as receipt of insulin or three oral agents. Facilities were ranked using five ordinal categories based up both z score distribution and statistical significance (P < 0.05). Rankings using the NCQA definition were compared with a subset receiving CGRs using both a <7% threshold and a continuous measure awarding proportional credit for values between 7.9 and <7.0%. Ranking correlation was assessed using the Spearman correlation coefficient. RESULTS: A total of 203,302 patients (mean age 55.2 years) were identified from 127 facilities (range 480-5,411, mean 1,601); 26.7% (17.9-35.2%) were receiving CGRs, including 22.0% receiving insulin. Mean A1C and percent achieving A1C <7% were 7.48 and 48% overall and 8.32 and 24.8% for those receiving CGRs using the threshold measure; proportion achieved was 60.1 and 37.2%, respectively, using the continuous measure. Rank correlation between the overall and CGR subset was 0.61; 8 of 24 of the highest or lowest ranked facilities changed to nonsignificance status; an additional five sites changed rankings. CONCLUSIONS: Facility rankings in achieving the NCQA <7% measure as specified differ markedly from rankings using the CGR subset. Measurement for public reporting or payment should stratify rankings by CGR. A continuous measure may better align incentives with treatment intensity.

Measuring the intensity of resident supervision in the department of veterans affairs: the resident supervision index.

PURPOSE: To develop a survey instrument designed to quantify supervision by attending physicians in nonprocedural care and to assess the instrument's feasibility and reliability. METHOD: In 2008, the Department of Veterans Affairs (VA) Office of Academic Affiliations convened an expert panel to adopt a working definition of attending supervision in nonprocedural patient care and to construct a survey to quantify it. Feasibility was field-tested on residents and their supervising attending physicians at primary care internal medicine clinics at the VA Loma Linda Healthcare System in their encounters with randomly selected outpatients diagnosed with either major depressive disorder or diabetes. The authors assessed both interrater concurrent reliability and test-retest reliability. RESULTS: The expert panel adopted the VA's definition of resident supervision and developed the Resident Supervision Index (RSI) to measure supervision in terms of residents' case understanding, attending physicians' contributions to patient care through feedback to the resident, and attending physicians' time (minutes). The RSI was field-tested on 60 residents and 37 attending physicians for 148 supervision episodes from 143 patient encounters. Consent rates were 94% for residents and 97% for attending physicians; test-retest reliability intraclass correlations (ICCs) were 0.93 and 0.88, respectively. Concurrent reliability between residents' and attending physicians' reported time was an ICC of 0.69. CONCLUSIONS: The RSI is a feasible and reliable measure of resident supervision that is intended for research studies in graduate medical education focusing on education outcomes, as well as studies assessing quality of care, patient health outcomes, care costs, and clinical workload.

The Department of Veterans Affairs National Quality Scholars Fellowship Program: experience from 10 years of training quality scholars.

The Department of Veterans Affairs (VA) National Quality Scholars Fellowship Program (VAQS) was established in 1998 as a postgraduate medical education fellowship to train physicians in new methods of improving the quality and safety of health care for veterans and the nation. The VAQS curriculum is based on adult learning theory, with a national core curriculum of face-to-face components, technologically mediated distance learning components, and a unique local curriculum that draws from the strengths of regional resources. VAQS has established strong ties with other VA programs. Fellows' research and quality improvement projects are integrated with local and regional VA leaders' priorities, enhancing the relevance and visibility of the fellows' efforts and promoting recruitment of fellows to VA positions. VAQS has enrolled 98 fellows since 1999; 75 have completed the program and 24 are currently enrolled. Fellowship graduates have pursued a variety of career paths: 17% are continuing training (most in VA), 31% hold a VA faculty/staff position, 66% are academic faculty, and 80% conduct clinical or research work related to health care improvement. Graduates have held leadership positions in VA, Department of Defense, academic medicine, and public health agencies. Combining knowledge about the improvement of health care with adult learning strategies, distance learning technologies, face-to-face meetings, local mentorship, and experiential projects has been successful in improving care in VA and preparing physicians to participate in, study, and lead the improvement of health care quality and safety.

Quality of care by a hypertension expert: a cautionary tale for pay-for-performance approaches.

CONTEXT: Pay-for-performance programs may be widely implemented, but gaps remain in our understanding of the implementation of performance measurement approaches. OBJECTIVES: To compare 3 approaches to hypertension quality measurement as applied to high-quality care delivered by a hypertension expert. METHODS: Care of 23 patients treated by a single hypertension expert was assessed by 3 measurement approaches: (1) outcome, (2) a multicomponent process, and (3) "outcome-linked" process. Exemplary case studies were identified to illustrate additional challenges to applying the approaches. RESULTS: Forty-four percent of patients (n = 10) had complete concordance between the outcome and outcome-linked process approaches, 22% of patients (n = 5) had complete concordance between the outcome and multicomponent process approaches, 52% of patients (n = 12) had complete concordance between outcome-linked process and multicomponent process approaches, and 22% of patients (n = 5) had uniform agreement among all 3 approaches. Case studies revealed numerous opportunities for misinterpretation or gaming by providers. CONCLUSIONS: Currently available measurement approaches resulted in a varied assessment of provider performance under optimal hypertension care conditions suggesting that caution is required before their use for provider compensation.

Disparities among the disadvantaged: variation in lipid management in the Ohio Medicaid program.

BACKGROUND: Racial disparities exist in cardiovascular disease (CVD) prevention, but other non-clinical factors may influence treatment, further exacerbating disparities. METHODS: Using Ohio Medicaid data from 1992 to 1999, we identified a sample of 19,106 individuals with CVD-related diagnoses or procedures. A review of pharmacy claims identified previous, new, and long-term users of lipid-lowering agents, including statins, fibrates, and bile sequestrants. RESULTS: 3,934 (20.6%) Medicaid beneficiaries used lipid-lowering medications previously, 1,598 (10.5%) filed new claims, and 2,998 of 5,532 (54.2%) previous or new users filed >or=6 claims for refills.

A curriculum for training quality scholars to improve the health and health care of veterans and the community at large.

In 1998, the Veterans Health Administration invested in the creation of the Veterans Administration National Quality Scholars Fellowship Program (VAQS) to train physicians in new ways to improve the quality of health care. We describe the curriculum for this program and the lessons learned from our experience to date. The VAQS Fellowship program has developed a core improvement curriculum to train postresidency physicians in the scholarship, research, and teaching of the improvement of health care. The curriculum covers seven domains of knowledge related to improvement: health care as a process; variation and measurement; customer/beneficiary knowledge; leading, following, and making changes in health care; collaboration; social context and accountability; and developing new, locally useful knowledge. We combine specific knowledge about the improvement of health care with the use of adult learning strategies, interactive video, and development of learner competencies. Our program provides insights for medical education to better prepare physicians to participate in and lead the improvement of health care.

Applying the theory of constraints in health care: Part 1--The philosophy.

The imperative to improve both technical and service quality while simultaneously reducing costs is quite clear. The Theory of Constraints (TOC) is an emerging philosophy that rests on two assumptions: (1) systems thinking and (2) if a constraint "is anything that limits a system from achieving higher performance versus its goal," then every system must have at least one (and at most no more than a few) constraints or limiting factors. A constraint is neither good nor bad in itself. Rather, it just is. In fact, recognition of the existence of constraints represents an excellent opportunity for improvement because it allows one to focus ones efforts in the most productive area--identifying and managing the constraints. This is accomplished by using the five focusing steps of TOC: (1) identify the system's constraint; (2) decide how to exploit it; (3) subordinate/synchronize everything else to the above decisions; (4) elevate the system's constraint; and (5) if the constraint has shifted in the above steps, go back to step 1. Do not allow inertia to become the system's constraint. TOC also refers to a series of tools termed "thinking processes" and the sequence in which they are used.
