Nurse Leader Perceptions of Data in the Veterans Health Administration: A Qualitative Evaluation.

Healthcare systems and nursing leaders aim to make evidence-based nurse staffing decisions. Understanding how nurses use and perceive available data to support safe staffing can strengthen learning healthcare systems and support evidence-based practice, particularly given emerging data availability and specific nursing challenges in data usability. However, current literature offers sparse insight into the nature of data use and challenges in the inpatient nurse staffing management context. We aimed to investigate how nurse leaders experience using data to guide their inpatient staffing management decisions in the Veterans Health Administration, the largest integrated healthcare system in the United States. We conducted semistructured interviews with 27 Veterans Health Administration nurse leaders across five management levels, using a constant comparative approach for analysis. Participants primarily reported using data for quality improvement, organizational learning, and organizational monitoring and support. Challenges included data fragmentation, unavailability and unsuitability to user need, lack of knowledge about available data, and untimely reporting. Our findings suggest that prioritizing end-user experience and needs is necessary to better govern evidence-based data tools for improving nursing care. Continuous nurse leader involvement in data governance is integral to ensuring high-quality data for end-user nurses to guide their decisions impacting patient care.

State-Level Social Vulnerability Index and Healthcare Access in Patients With Atherosclerotic Cardiovascular Disease (from the BRFSS Survey).

We analyzed the association between social vulnerability index (SVI) and healthcare access among patients with atherosclerotic cardiovascular disease (ASCVD). Using cross-sectional data from the Behavioral Risk Factor Surveillance System 2016 to 2019, we identified measures related to healthcare access in individuals with ASCVD, which included healthcare coverage, presence of primary care clinician, duration since last routine checkup, delay in access to healthcare, inability to see doctor because of cost, and cost-related medication nonadherence. We analyzed the association of state-level SVI (higher SVI denotes higher social vulnerability) and healthcare access using multivariable-adjusted logistic regression models. The study population comprised 203,347 individuals aged 18 years or older who reported a history of ASCVD. In a multivariable-adjusted analysis, prevalence odds ratios (95% confidence interval) for participants residing in states in the third tertile of SVI compared with those in the first tertile (used as reference) were as follows: absence of healthcare coverage = 1.03 (0.85 to 1.24), absence of primary care clinician = 1.33 (1.12 to 1.58), >1 year since last routine checkup = 1.09 (0.96 to 1.23), delay in access to healthcare = 1.39 (1.18, 1.63), inability to see a doctor because of cost = 1.21 (1.06 to 1.40), and cost-related medication nonadherence = 1.10 (0.83 to 1.47). In conclusion, SVI is associated with healthcare access in those with pre-existing ASCVD. Due to the ability of SVI to simultaneously and holistically capture many of the factors of social determinants of health, SVI can be a useful measure for identifying high-risk populations.

Eligibility for Low-Dose Rivaroxaban Based on the COMPASS Trial: Insights from the Veterans Affairs Healthcare System.

INTRODUCTION: Low-dose rivaroxaban reduced major adverse cardiac and limb events among patients with stable atherosclerotic vascular disease (ASCVD) in the COMPASS trial. The objective of our study was to evaluate the eligibility and budgetary impact of the COMPASS trial in a real-world population. METHODS: The VA administrative and clinical databases were utilized to conduct a cross-sectional study to identify patients eligible for low-dose rivaroxaban receiving care at all 141 facilities between October 1, 2014 and September 30, 2015. Proportion of patients with stable ASCVD eligible for low-dose rivaroxaban and prevalence of multiple risk enrichment criteria among eligible patients. Pharmaceutical budgetary impact using VA pharmacy pricing. Chi-squared and Student's t tests were used to compare patients eligible versus ineligible patients. RESULTS: From an initial cohort of 1,248,214 patients with ASCVD, 488,495 patients (39.1%) met trial eligibility criteria. Eligible patients were older (74.2 vs 64.5 years) with higher proportion of hypertension (84.1% vs 82.1%) and diabetes (46.2% vs 32.9) compared with ineligible patients (p < 0.001 for all comparisons). A median of 38.7% (IQR 4.6%) of total ASCVD patients per facility were rivaroxaban eligible. Estimated annual VA pharmacy budgetary impact would range from $0.47 billion to $1.88 billion for 25% to 100% treatment penetration. Annual facility level pharmaceutical budgetary impact would be a median of $12.3 million (IQR $8.0-$16.3 million) for treatment of all eligible patients. Among eligible patients, age greater than 65 years was the most common risk enrichment factor (86.9%). Prevalence of eligible patients with multiple enrichment factors varied from 34.2% (one factor) to 6.2% (four or more). CONCLUSION: Over one third of patients with stable ASCVD may qualify for low-dose rivaroxaban within the VA. Additional studies are needed to understand eligibility in other populations and a formal cost-effectiveness analysis is warranted.

Using a multifaceted approach to improve the follow-up of positive fecal occult blood test results.

OBJECTIVES: Inadequate follow-up of abnormal fecal occult blood test (FOBT) results occurs in several types of practice settings. Our institution implemented multifaceted quality improvement (QI) activities in 2004-2005 to improve follow-up of FOBT-positive results. Activities addressed precolonoscopy referral processes and system-level factors such as electronic communication, provider education, and feedback. We evaluated their effects on timeliness and appropriateness of positive-FOBT follow-up and identified factors that affect colonoscopy performance. METHODS: Retrospective electronic medical record review was used to determine outcomes before and after QI activities in a multispecialty ambulatory clinic of a tertiary care Veterans Affairs facility and its affiliated satellite clinics. From 1869 FOBT-positive cases, 800 were randomly selected from time periods before and after QI activities. Two reviewers used a pretested standardized data collection form to determine whether colonoscopy was appropriate or indicated based on predetermined criteria and if so, the timeliness of colonoscopy referral and performance before and after QI activities. RESULTS: In cases where a colonoscopy was indicated, the proportion of patients who received a timely colonoscopy referral and performance were significantly higher post-implementation (60.5% vs. 31.7%, P<0.0001 and 11.4% vs. 3.4%, P=0.0005). A significant decrease also resulted in median times to referral and performance (6 vs. 19 days, P<0.0001 and 96.5 vs. 190 days, P<0.0001) and in the proportion of positive-FOBT test results that had received no follow-up by the time of chart review (24.3% vs. 35.9%, P=0.0045). Significant predictors of absence of the performance of an indicated colonoscopy included performance of a non-colonoscopy procedure such as barium enema or flexible sigmoidoscopy (OR=16.9; 95% CI, 1.9-145.1), patient non-adherence (OR=33.9; 95% CI, 17.3-66.6), not providing an appropriate provisional diagnosis on the consultation (OR=17.9; 95% CI, 11.3-28.1), and gastroenterology service not rescheduling colonoscopies after an initial cancellation (OR=11.0; 95% CI, 5.1-23.7). CONCLUSIONS: Multifaceted QI activities improved rates of timely colonoscopy referral and performance in an electronic medical record system. However, colonoscopy was not indicated in over one third of patients with positive FOBTs, raising concerns about current screening practices and the appropriate denominator used for performance measurement standards related to colon cancer screening.

Psychotherapy in the Veterans Health Administration: Missed Opportunities?

Informed by data on the dose-response effect, the authors assessed use of psychotherapy in the Veterans Health Administration (VA). The authors identified 410,923 patients with newly diagnosed depression, anxiety, or posttraumatic stress disorder using VA databases (October 2003 through September 2004). Psychotherapy encounters were identified by Current Procedural Terminology codes for the 12 months following patients' initial diagnosis. Psychotherapy was examined for session exposure received within the 12-month follow-up period and time (in days) between diagnosis and treatment. Of the cohort, 22% received at least one session of psychotherapy; 7.9% received four or more sessions; 4.2% received eight or more sessions; and 2.4% received 13 or more sessions. Delays between initial mental health diagnosis and initiation of care averaged 57 days. Patient variables including age, marital status, income, travel distance, psychiatric diagnosis, and medical-illness burden were significantly related to receipt of psychotherapy. Treatment delays and general underuse of psychotherapy services are potential missed opportunities for higher-quality psychotherapeutic care in integrated health care settings.

Health care funding levels and patient outcomes: a national study.

BACKGROUND: Health care funding levels differ significantly across geographic regions, but there is little correlation between regional funding levels and outcomes of elderly Medicare beneficiaries. Our goal was to determine whether this relationship holds true in a non-Medicare population cared for in a large integrated health care system with a capitated budget allocation system. METHODS: We explored the association between health care funding and risk-adjusted mortality in the 22 Veterans Affairs (VA) geographic Networks over a six-year time period. Allocations to Networks were adjusted for illness burden using Diagnostic Cost Groups. To test the association between funding and risk-adjusted three-year mortality, we ran logistic regressions with single-year patient cohorts, as well as hierarchical regressions on a six year longitudinal data set, clustering on VA Network. RESULTS: A 1000 dollar increase in funding per unit of patient illness burden was associated with a 2-8% reduction in three-year mortality in cross sectional regressions. However, in longitudinal hierarchical regressions clustering on Network, the significant effect of funding level was eliminated. CONCLUSIONS: When longitudinal data are used, the significant cross sectional effect of funding levels on mortality disappear. Thus, the factors driving differences in mortality are Network effects, although part of the Network effect may be due to past levels of funding. Our results provide a caution for cross sectional examinations of the association between regional health care funding levels and health outcomes.

Outcomes after acute coronary syndrome admission to primary versus tertiary Veterans Affairs medical centers: the Veterans Affairs Access to Cardiology study.

BACKGROUND: There is a concern that patients with acute coronary syndrome (ACS) admitted to primary care hospitals (without on-site cardiac procedures) may be at risk for worse outcomes compared with patients admitted to tertiary care hospitals. In addition to mortality, one way to assess patient outcomes is via health status and rehospitalization rates. We compared the health status and rehospitalization of patients with ACS admitted to primary versus tertiary care Veterans Affairs hospitals. METHODS: This was a cohort study of 2132 patients with ACS admitted to 21 Veterans Affairs hospitals (12 primary care and 9 tertiary care) from 1998 to 1999. Primary outcomes were 7-month health status as measured by the Seattle Angina Questionnaire and rehospitalization. Hierarchical multivariable regression was used to evaluate the association between admission to a primary (vs tertiary) care hospital and these outcomes. Discharge medications and 7-month cardiac procedure rates were also compared. RESULTS: There were no significant differences in discharge medication rates between primary and tertiary hospital patients. Forty-two percent of the patients admitted to a primary care hospital was transferred to a tertiary care hospital during index admission. Primary hospital patients had significantly lower 7-month rates of cardiac catheterization (36% vs 51%, P < .001) and percutaneous coronary intervention (11% vs 20%, P < .001), but there were no differences in coronary artery bypass graft surgery rates. After risk adjustment, there were no significant differences in 7-month angina frequency (odds ratio [OR] 0.98, 95% CI 0.78-1.22), physical limitation (OR 0.97, 95% CI 0.77-1.23), quality of life (OR 1.12, 95% CI 0.89-1.40), or rehospitalization (OR 1.07, 95% CI 0.54-2.14) between the 2 groups. CONCLUSIONS: These results suggest that an integrated health care system can achieve similar intermediate-term health status and rehospitalization outcomes for patients with ACS irrespective of the site of admission despite the lower rates of cardiac procedures for the primary care hospital patients.

Process of care and outcome after acute myocardial infarction for patients with mental illness in the VA health care system: are there disparities?

OBJECTIVE: To compare process of care and outcome after acute myocardial infarction, for patients with and without mental illness, cared for in the Veterans Health Administration (VA) health care system. DATA SOURCES/SETTING: Primary clinical data from 81 VA hospitals. STUDY DESIGN: This was a retrospective cohort study of 4,340 veterans discharged with clinically confirmed acute myocardial infarction. Of these, 859 (19.8 percent) met the definition of mental illness. Measures were age-adjusted in-hospital and 90-day cardiac procedure use; age-adjusted relative risks (RE) of use of thrombolytic therapy, beta-blockers, angiotensin converting enzyme (ACE) inhibitors, or aspirin at discharge; risk-adjusted 30-day and one-year mortality. RESULTS: Patients with mental illness were marginally less likely than those without mental illness to undergo in-hospital angiography (age-adjusted RR 0.90 [95 percent confidence interval: 0.83, 0.98]), but there was no significant difference in the age-adjusted RR of coronary artery bypass graft surgery in the 90 days after admission (0.85 [0.69, 1.05]), or in the receipt of medications of known benefit. For example, ideal candidates with and without mental illness were equally likely to receive beta-blockers at the time of discharge (age-adjusted RR 0.92 [0.82, 1.02]). The risk-adjusted odds ratio (OR) for death in patients with mental illness versus those without mental illness within 30 days was 1.00 (0.75, 1.32), and for death within one year was 1.25 (1.00, 1.53). CONCLUSIONS: Veterans Health Administration patients with mental illness were marginally less likely than those without mental illness to receive diagnostic angiography, and no less likely to receive revascularization or medications of known benefit after acute myocardial infarction. Mortality at one year may have been higher, although this finding did not reach statistical significance. These findings are consistent with other studies showing reduced health care disparities in the VA for other vulnerable groups, and suggest that an integrated health care system with few financial barriers to health care access may attenuate some health care disparities. Further work should address how health care organizational features might narrow disparities in health care for vulnerable groups.

Impact of race on cardiac care and outcomes in veterans with acute myocardial infarction.

OBJECTIVES: The goal of this study was to assess racial differences in process of care and outcome for acute myocardial infarction in the VA health care system. DESIGN: Retrospective cohort study using clinical data. SETTING: Eighty-one acute care VA hospitals. PATIENTS: Four thousand seven hundred sixty veterans discharged with a confirmed diagnosis of acute myocardial infarction. The analysis was restricted to 606 black and 4005 white patients. MAIN OUTCOME MEASURES: Comparison of use of guideline-based medications, invasive cardiac procedures, and all-cause mortality at 30 days, 1 year, and 3 years. RESULTS: Black patients were equally likely to receive beta-blockers, more likely than white patients to receive aspirin (86.8% vs. 82.0%; P <0.05), and marginally more likely to receive angiotensin converting enzyme inhibitors (55.7% vs. 49.6%; P = 0.07) at the time of discharge. In contrast, black patients were less likely than white patients to receive thrombolytic therapy at the time of arrival (32.4% vs. 48.2%; P <0.01). There was no significant difference in refusal of angiography or percutaneous transluminal coronary angioplasty between black patients and white patients, or in crude rates of either of these procedures. There was also no difference overall in the percentage of patients who refused coronary artery bypass graft surgery. However, black patients were less likely than white patients to undergo bypass surgery (6.9% vs. 12.5% by 90 days; P <0.001). Black patients remained less likely to undergo bypass surgery even when high-risk specific coronary anatomy subgroups were examined. There was no difference in mortality in the two groups. CONCLUSIONS: In this integrated health care system, no significant racial disparities in use of noninterventional therapies, diagnostic coronary angiography, or short- or long-term mortality was found. Disparities in use of thrombolytic therapy and coronary artery bypass surgery existed, however, even after accounting for differences in clinical indications for treatment and patient refusals. Further work should assess the role of the medical interaction and physician behavior in racial disparities in use of health care.
