Developing a relational playbook for cardiology teams to cultivate supportive learning environments, enhance clinician well-being, and veteran care.

Introduction: Despite the Veterans Health Administration (VA) efforts to become a learning health system (LHS) and high-reliability organization (HRO), interventions to build supportive learning environments within teams are not reliably implemented, contributing to high levels of burnout, turnover, and variation in care. Supportive learning environments build capabilities for teaching and learning, empower teams to safely trial and adapt new things, and adopt highly reliable work practices (eg, debriefs). Innovative approaches to create supportive learning environments are needed to advance LHS and HRO theory and research into practice. Methods: To guide the identification of evidence-based interventions that cultivate supportive learning environments, the authors used a longitudinal, mixed-methods design and LHS and HRO frameworks. We partnered with the 81 VA cardiac catheterization laboratories and conducted surveys, interviews, and literature reviews that informed a Relational Playbook for Cardiology Teams. Results: The Relational Playbook resources and 50 evidence-based interventions are organized into five LHS and HRO-guided chapters: Create a positive culture, teamwork, leading teams, joy in work, communication, and high reliability. The interventions are designed for managers to integrate into existing meetings or trainings to cultivate supportive learning environments. Conclusions: LHS and HRO frameworks describe how organizations can continually learn and deliver nearly error-free services. The Playbook resources and interventions translate LHS and HRO frameworks for real-world implementation by healthcare managers. This work will cultivate supportive learning environments, employee well-being, and Veteran safety while providing insights into LHS and HRO theory, research, and practice.

Conducting health services research during the COVID-19 pandemic: experiences from the veterans health administration.

BACKGROUND: Health services researchers within the Veterans Health Administration (VA) seek to improve the delivery of care to the Veteran population, whose medical needs often differ from the general population. The COVID-19 pandemic and restricted access to medical centers and offices forced VA researchers and staff to transition to remote work. This study aimed to characterize the work experience of health service researchers during the COVID-19 pandemic. METHODS: A REDCap survey developed from the management literature was distributed in July 2020 to 800 HSR&D researchers and staff affiliated with VA Centers of Innovation. We requested recipients to forward the survey to VA colleagues. Descriptive analyses and logistic regression modeling were conducted on multiple choice and Likert scaled items. Manifest content analysis was conducted on open-text responses. RESULTS: Responses were received from 473 researchers and staff from 37 VA Medical Centers. About half (48%; n = 228) of VA HSR&D researchers and staff who responded to the survey experienced some interference with their research due to the COVID-19 pandemic, yet 55% (n = 260) reported their programs of research did not slow or stop. Clinician investigators reported significantly greater odds of interference than non-clinician investigators and support staff. The most common barriers to working remotely were loss of face-to-face interactions with colleagues (56%; n = 263) and absence of daily routines (25%; n = 118). Strategies teams used to address COVID-19 related remote work challenges included videoconferencing (79%; n = 375), virtual get-togethers (48%; n = 225), altered timelines (42%; n = 199), daily email updates (30%; n = 143) and virtual team huddles (16%; n = 74). Pre-pandemic VA information technology structures along with systems created to support multidisciplinary research teams working across a national healthcare system maintained and enhanced staff engagement and well-being. CONCLUSIONS: This study identifies how the VA structures and systems put in place prior to the COVID-19 pandemic to support a dispersed workforce enabled the continuation of vital scientific research, staff engagement and well-being during a global pandemic. These findings can inform remote work policies and practices for researchers during the current and future crises.

Elevated Pulmonary Arterial Compliance Is Associated with Survival in Pulmonary Hypertension: Results from a Novel Network Medicine Analysis.

Rationale: Predictors of adverse outcome in pulmonary hypertension (PH) are well established; however, data that inform survival are lacking. Objectives: We aim to identify clinical markers and therapeutic targets that inform the survival in PH. Methods: We included data from patients with elevated mean pulmonary artery pressure (mPAP) diagnosed by right heart catheterization in the U.S. Veterans Affairs system (October 1, 2006-September 30, 2018). Network medicine framework was used to subgroup patients when considering an N of 79 variables per patient. The results informed outcome analyses in the discovery cohort and a sex-balanced validation right heart catheterization cohort from Vanderbilt University (September 24, 1998-December 20, 2013). Measurements and Main Results: From an N of 4,737 complete case patients with mPAP of 19-24 mm Hg, there were 21 distinct subgroups (network modules) (all-cause mortality range = 15.9-61.2% per module). Pulmonary arterial compliance (PAC) drove patient assignment to modules characterized by increased survival. When modeled continuously in patients with mPAP ⩾19 mm Hg (N = 37,744; age, 67.2 yr [range = 61.7-73.8 yr]; 96.7% male; median follow-up time, 1,236 d [range = 570-1,971 d]), the adjusted all-cause mortality hazard ratio was <1.0 beginning at PAC ⩾3.0 ml/mm Hg and decreased progressively to ∼7 ml/mm Hg. A protective association between PAC ⩾3.0 ml/mm Hg and mortality was also observed in the validation cohort (N = 1,514; age, 60.2 yr [range = 49.2-69.1 yr]; 48.0% male; median follow-up time, 2,485 d [range = 671-3,580 d]). The association was strongest in patients with precapillary PH at the time of catheterization, in whom 41% (95% confidence interval, 0.55-0.62; P < 0.001) and 49% (95% confidence interval, 0.38-0.69; P < 0.001) improvements in survival were observed for PAC ⩾3.0 versus <3.0 ml/mm Hg in the discovery and validation cohorts, respectively. Conclusions: These data identify elevated PAC as an important parameter associated with survival in PH. Prospective studies are warranted that consider PAC ⩾3.0 ml/mm Hg as a therapeutic target to achieve through proven interventions.

Impact of severity of baseline thrombocytopenia on outcomes after percutaneous coronary interventions: Analysis from the Veterans Affairs Clinical Assessment, Reporting, and Tracking (VA CART) Program.

OBJECTIVES: The aim of this study was to evaluate the effect of the degree of severity of baseline thrombocytopenia (TCP) on outcomes after percutaneous coronary intervention (PCI) BACKGROUND: The association of TCP with clinical outcomes among patients undergoing coronary intervention has not been previously evaluated. METHODS: Using data from the US Veterans Affairs Clinical Assessment, Reporting, and Tracking (CART) Program, we identified patients undergoing PCI between October 1, 2007, to September 30, 2017. The cohort was then stratified by platelet count, as no TCP (platelet count >150,000/mcl), mild TCP (100-150,000/mcl), or moderate-severe TCP (<100,000/mcl) and this was associated with clinical outcomes. RESULTS: The cohort included 80,427 patients (98% male), of which 14.9% (13.2% mild, 1.7% moderate-severe) suffered from TCP at the time of PCI. Compared with mild or no TCP, moderate-severe TCP was associated with increased risk of post-PCI pericardiocentesis (0.6% vs. 0.2% vs. 0.2%, p = 0.018) and in-hospital mortality (1.5% vs. 0.7% vs. 0.7%) without a difference in postprocedure stroke (0.5% vs. 0.3% vs. 0.3%, p = 0.6). Over a median follow-up of 1729 days, time-to-repeat revascularization was significantly shorter in moderate-severe TCP (1080 vs. 1347 vs. 1467 days, p < 0.001) despite lower risk of revascularization. Both mild (adjusted HR: 1.11, 95% CI: 1.07-1.15, p < 0.001) and moderate-severe TCP (HR: 1.55, 95% CI: 1.43-1.69, p < 0.001) were associated with increased all-cause mortality compared with those without TCP. CONCLUSIONS: Thrombocytopenia was associated with increased short- and long-term adverse events among patients undergoing PCI. Any degree of TCP was associated with increased long-term all-cause mortality while moderate-severe TCP was also associated with increased risk of periprocedural adverse events.

Learning environments, reliability enhancing work practices, employee engagement, and safety climate in VA cardiac catheterization laboratories.

OBJECTIVE: To characterize the relationship between learning environments (the educational approaches, cultural context, and settings in which teaching and learning happen) and reliability enhancing work practices (hiring, training, decision making) with employee engagement, retention, and safety climate. DATA SOURCE: We collected data using the Learning Environment and High Reliability Practices Survey (LEHRs) from 231 physicians, nurses, and technicians at 67 Veterans Affairs cardiac catheterization laboratories who care for high-risk Veterans. STUDY DESIGN: The association between the average LEHRs score and employee job satisfaction, burnout, intent to leave, turnover, and safety climate were modeled in separate linear mixed effect models adjusting for other covariates. DATA COLLECTION: Participants responded to a web-only survey from August through September 2020. PRINCIPAL FINDINGS: There was a significant association between higher average LEHRs scores and (1) higher job satisfaction (2) lower burnout, (3) lower intent to leave, (4) lower cath lab turnover in the previous 12 months, and (5) higher perceived safety climate. CONCLUSIONS: Learning environments and use of reliability enhancing work practices are potential new avenues to support satisfaction and safety climate while lowering burnout, intent to leave, and turnover in a diverse US health care workforce that serves a vulnerable and marginalized population.

Two Factor Structures Possible for the FACIT-Sp in Patients With Heart Failure.

CONTEXT: The Functional Assessment of Chronic Illness Therapy-Spiritual Well-Being Scale (FACIT-Sp) is a 12-item measure of spiritual well-being in chronic illness originally developed in patients with cancer. The overall scale, a two-factor model (meaning/peace, faith), and a three-factor model (meaning, peace, faith) have been proposed for the FACIT-Sp, and consensus on the best factor structure has not been reached. In addition, the factor structure of the FACIT-Sp has not been considered in patients with heart failure. OBJECTIVES: To examine the factor structure of the FACIT-Sp in heart failure patients. METHODS: A confirmatory factor analysis framework was used to test three competing models on 217 patients with heart failure using data from the CASA (Collaborative Care to Alleviate Symptoms and Adjust to Illness) trial. The overall scale (single factor), two-factor, and three-factor models were tested using baseline data, then confirmed with 12-month data. Model modifications were made based on empirical inspection of baseline data and replicated using 12-month data. Cronbach's alpha and correlations with measures of quality of life and psychological health were examined. RESULTS: All three models had strong factor loadings on all items except the negatively worded items. The two-factor and three-factor models fit reasonably well after modifications, but the single factor did not fit well (1/2/3-factor: RMSEA 0.14/0.09/0.06, CFI 0.85/0.93/0.97, SRMR 0.09/0.05/0.04). Internal consistency was sufficient for all factors. CONCLUSION: The two-factor and three-factor models were supported in heart failure patients. The three-factor model demonstrated better statistical fit but was not more interpretable. KEY MESSAGE: This study investigated the factor structure of the FACIT-Sp in patients with heart failure. The two-factor and three-factor models were supported, but the single factor model was not. Negatively worded items did not perform well.

A pilot study to assess the learning environment and use of reliability enhancing work practices in VHA cardiac catheterization laboratories.

INTRODUCTION: A learning health system (LHS) harnesses data and analytics to learn from clinical encounters to implement the best care with high reliability. The 81 Veterans Health Administration (VHA) cardiac catheterization laboratories (cath lab) are a model LHS. The quality and safety of coronary procedures are monitored and reported by the Clinical Assessment, Reporting and Tracking (CART) Program, which has identified variation in care across cath labs. This variation may be due to underappreciated aspects of LHSs, the learning environment and reliability enhancing work practices (REWPs). Learning environments are the educational approaches, context, and settings in which learning occurs. REWPs are the organizational practices found in high reliability organizations. High learning environments and use of REWPs are associated with improved outcomes. This study assessed the learning environments and use of REWPs in VHA cath labs to examine factors supportive of learning and high reliability. METHODS: In 2018, the learning organization survey-27 and the REWP survey were administered to 732 cath lab staff. Factor analysis and linear models were computed. Unit-level analyses and site ranking (high, low) were conducted on cath labs with >40% response rate using Bayesian methods. RESULTS: Surveys from 40% of cath lab staff (n = 294) at 84% of cath labs (n = 68) were included. Learning environment and REWP strengths across cath labs include the presence of training programs, openness to new ideas, and respectful interaction. Learning environment and REWP gaps include lack of structured knowledge transfer (eg, checklists) and low use of forums for improvement. Survey dimensions matched established factor structures and demonstrated high reliability (Cronbach's alpha >.76). Unit-level analyses were conducted for 29 cath labs. One ranked as high and four as low learning environments. CONCLUSIONS: This work demonstrates an approach to assess local learning environments and use of REWPs, providing insights for systems working to become a LHS.

Renin-Angiotensin-Aldosterone System Inhibitor Use and Mortality in Pulmonary Hypertension: Insights From the Veterans Affairs Clinical Assessment Reporting and Tracking Database.

BACKGROUND: The renin-angiotensin-aldosterone system (RAAS) contributes to pulmonary hypertension (PH) pathogenesis. Although animal data suggest that RAAS inhibition attenuates PH, it is unknown if RAAS inhibition is beneficial in PH patients. RESEARCH QUESTION: Is RAAS inhibitor use associated with lower mortality in a large cohort of patients with hemodynamically confirmed PH? STUDY DESIGN AND METHODS: We used the Department of Veterans Affairs Clinical Assessment Reporting and Tracking Database to study retrospectively relationships between RAAS inhibitors (angiotensin converting enzyme inhibitors [ACEIs], angiotensin receptor blockers [ARBs], and aldosterone antagonists [AAs]) and mortality in 24,221 patients with hemodynamically confirmed PH. We evaluated relationships in the full and in propensity-matched cohorts. Analyses were adjusted for demographics, socioeconomic status, comorbidities, disease severity, and comedication use in staged models. RESULTS: ACEI and ARB use was associated with improved survival in unadjusted Kaplan-Meier survival analyses in the full cohort and the propensity-matched cohort. This relationship was insensitive to adjustment, independent of pulmonary artery wedge pressure, and also was observed in a cohort restricted to individuals with precapillary PH. AA use was associated with worse survival in unadjusted Kaplan-Meier survival analyses in the full cohort; however, AA use was associated less robustly with mortality in the propensity-matched cohort and was not associated with worse survival after adjustment for disease severity, indicating that AAs in real-world practice are used preferentially in sicker patients and that the unadjusted association with increased mortality may be an artifice of confounding by indication of severity. INTERPRETATION: ACEI and ARB use is associated with lower mortality in veterans with PH. AA use is a marker of disease severity in PH. ACEIs and ARBs may represent a novel treatment strategy for diverse PH phenotypes.

Long-term predictive value of stroke volume index obtained from right heart catheterization: Insights from the veterans affairs clinical assessment, reporting, and tracking program.

BACKGROUND: Right heart catheterization-derived hemodynamic parameters have been associated with short-term prognosis. HYPOTHESIS: Hemodynamic parameters will be associated with long-term prognosis. METHODS: Retrospective cohort study from the Veterans Affairs Clinical Assessment, Reporting, and Tracking Program included patients who underwent an index right heart catheterization between 2008 and 2016. Cox proportional hazard models were used to examine the association between stroke volume index and all-cause mortality. RESULTS: For the final cohort of 37 209 patients, mean follow-up was 3.7 ± 2.5 years. All-cause mortality was 42.0% in the low (<35 cc/beat/m2 ) compared with 33.2% in the normal stroke volume index group (≥35 cc/beat/m2 ). In adjusted analysis, low stroke volume was significantly associated with higher mortality risk (HR (95% CI) 1.14 (1.10-1.18); P < .001) independent of clinical parameters. The area under the curve (AUC) for continuous measures of stroke volume index at predicting mortality in a Cox proportional hazard model was 0.56 at 3 years. When stroke volume index was combined with 14 clinical covariates, the AUC was 0.70 at 3 years. The addition of stroke volume index to these clinical covariates did not increase the discriminatory ability of the model at 1 year in a clinically meaningful way (integrated discrimination improvement index = 0.0021, 95% CI: 0.0010-0.0034). CONCLUSIONS: The long-term prognostic value of right heart catheterization-derived stroke volume index appears to be marginal. While there was a weak association of low stroke volume index and excess mortality, inclusion of this parameter to a set of clinical covariates did not improve prognostic discrimination.

Pulmonary vascular resistance and clinical outcomes in patients with pulmonary hypertension: a retrospective cohort study.

BACKGROUND: In pulmonary hypertension subgroups, elevated pulmonary vascular resistance (PVR) of 3·0 Wood units or more is associated with poor prognosis. However, the spectrum of PVR risk in pulmonary hypertension is not known. To address this area of uncertainty, we aimed to analyse the relationship between PVR and adverse clinical outcomes in pulmonary hypertension. METHODS: We did a retrospective cohort study of all patients undergoing right heart catheterisation (RHC) in the US Veterans Affairs health-care system (Oct 1, 2007-Sep 30, 2016). Patients were included in the analyses if data from a complete RHC and at least 1 year of follow-up were available. Both inpatients and outpatients were included, but individuals with missing mean pulmonary artery pressure (mPAP), pulmonary artery wedge pressure, or cardiac output were excluded. The primary outcome measure was time to all-cause mortality assessed by the Veteran Affairs vital status file. Cox proportional hazards models were used to assess the association between PVR and outcomes, and the mortality hazard ratio was validated in a RHC cohort from Vanderbilt University Medical Center (Sept 24, 1998-June 1, 2016). FINDINGS: The primary cohort (N=40 082; 38 751 [96·7%] male; median age 66·5 years [IQR 61·1-73·5]; median follow-up 1153 days [IQR 570-1971]), included patients with a history of heart failure (23 201 [57·9%]) and chronic obstructive pulmonary disease (13 348 [33·3%]). We focused on patients at risk for pulmonary hypertension based on a mPAP of at least 19 mm Hg (32 725 [81·6%] of 40 082). When modelled as a continuous variable, the all-cause mortality hazard for PVR was increased at around 2·2 Wood units compared with PVR of 1·0 Wood unit. Among patients with a mPAP of at least 19 mm Hg and pulmonary artery wedge pressure of 15 mm Hg or less, the adjusted hazard ratio (HR) for mortality was 1·71 (95% CI 1·59-1·84; p<0·0001) and for heart failure hospitalisation was 1·27 (1·13-1·43; p=0·0001), when comparing PVR of 2·2 Wood units or more to less than 2·2 Wood units. The validation cohort (N=3699, 1860 [50·3%] male, median age 60·4 years [49·5-69·2]; median follow-up 1752 days [IQR 1281-2999]) included 2870 patients [77·6%] with mPAP of at least 19 mm Hg (1418 [49·4%] male). The adjusted mortality HR for patients in the mPAP of 19 mm Hg or more group and with PVR of 2·2 Wood units or more and pulmonary artery wedge pressure of 15 mm or less Hg (1221 [42·5%] of 2870) was 1·81 (95% CI 1·33-2·47; p=0·0002). INTERPRETATION: These data widen the continuum of clinical risk for mortality and heart failure in patients referred for RHC with elevated pulmonary artery pressure to include PVR of around 2.2 Wood units and higher. Testing the generalisability of these findings in at-risk populations with fewer cardiopulmonary comorbidities is warranted. FUNDING: None.

Predicting Hospital Readmissions from Home Healthcare in Medicare Beneficiaries.

OBJECTIVE: To use patient-level clinical variables to develop and validate a parsimonious model to predict hospital readmissions from home healthcare (HHC) in Medicare fee-for-service beneficiaries. DESIGN: Retrospective analysis using multivariable logistic regression and gradient boosting machine (GBM) learning to develop and validate a predictive model. SETTING/PARTICIPANTS/MEAUREMENTS: A 5% national sample of patients, aged 65 years or older, with Medicare fee-for-service who received skilled HHC services within 5 days of hospital discharge in 2012 (n = 43 407). Multiple data sets were merged, including Medicare Outcome and Assessment Information Set, Home Health Claims, Medicare Provider Analysis and Review, and Master Beneficiary Summary Files, to extract patient-level variables from the first HHC visit after discharge and measure 30-day readmission outcomes. RESULTS: Among 43 407 patients with inpatient hospitalizations followed by HHC, 14.7% were readmitted within 30 days. Of the 53 candidate variables, seven remained in the final model as individually predictive of outcome: Elixhauser comorbidity index, index hospital length of stay, urinary catheter presence, patient status (ie, fragile health with high risk of complications or serious progressive condition), two or more hospitalizations in prior year, pressure injury risk or presence, and surgical wound presence. Of interest, surgical wounds, either from a total hip or total knee arthroplasty procedure or another surgical procedure, were associated with fewer readmissions. The optimism-corrected c-statistics for the full model and parsimonious model were 0.67 and 0.66, respectively, indicating fair discrimination. The Brier score for both models was 0.120, indicating good calibration. The GBM model identified similar predictive variables. CONCLUSION: Variables available to HHC clinicians at the first postdischarge HHC visit can predict readmission risk and inform care plans in HHC. Future analyses incorporating measures of social determinants of health, such as housing instability or social support, have the potential to enhance prediction of this outcome.

Outcomes of Transradial PCI compared to Transfemoral PCI in veterans with anemia: Insight from the VA Clinical Assessment, Reporting and Tracking (CART) program.

BACKGROUND: Pre-procedural anemia is associated with increased bleeding and mortality post-percutaneous coronary intervention (PCI). The effect of trans-radial PCI (TR-PCI) in improving outcomes compared to trans-femoral PCI (TF-PCI) in anemic patients is not known. OBJECTIVE: The aim of this study was to evaluate the association between arterial access site (radial versus femoral) and outcomes in anemic Veterans undergoing PCI. METHODS: Patients with baseline anemia, undergoing PCI at Veterans Affairs (VA) facilities between 2009 and 2015, were divided into two groups based on primary radial or femoral access. The association between anemia and access site with in-hospital and one-year adverse outcomes was evaluated using multivariable analysis. RESULTS: 7330 veterans were included in the analysis, with 1712 (23%) treated via radial access. Baseline anemia was independently associated with in-hospital major bleeding (OR 3.8, 95% CI 2.5-5.6 for moderate anemia, OR 18.6, 95% CI 11.6-29.7 for severe anemia), and in-hospital mortality (OR 3.2, 95% CI 1.8-5.8 for moderate anemia, OR 7.9, 95% CI 3.7-16.8 for severe anemia). Anemia was also associated with increased one-year MACE and mortality. PCI performed via radial access was not associated with different outcomes compared with femoral access in the presence of anemia. Comparable results were noted when analysis was restricted to only patients with acute coronary syndrome (ACS). CONCLUSIONS: Moderate and severe anemia were strongly associated with increased in-hospital and one-year mortality in a large healthcare system, though there was no interaction between arterial access site for PCI and clinical outcomes among patients with moderate or severe anemia.

Depression and long-term prognostic outcomes following peripheral endovascular interventions in the VA Healthcare System.

The association between depression and peripheral artery disease (PAD) outcomes remains widely understudied. In patients with PAD undergoing a peripheral vascular intervention (PVI) who have a recent diagnosis of depression, it is unknown what their long-term outcomes are and what factors may mediate an adverse risk. We therefore studied 797 consecutive patients undergoing PVI across 33 Veterans Affairs (VA) centers. Depression and outcomes were documented from patients' medical records. Outcomes included: (1) all-cause death; (2) non-fatal cardiovascular events (myocardial infarction, stroke); and (3) PAD-related events (including repeat PVI or amputation). Cox proportional hazards frailty models were constructed, adjusting for age. Additional covariates were selected if they resulted in at least 5% change in the age-adjusted hazard ratio (HR) for depression on outcomes. Overall, 265 (33%) patients had a diagnosis of depression. After a median follow-up of 955 days (range 1-6.25 years), 52 (6.5%) patients died, 30 (3.8%) experienced non-fatal cardiovascular events, and 176 (22.1%) had PAD-related events. Compared to patients without depression, depressed patients had higher rates of non-fatal cardiovascular events (6.4% vs 2.4%, p-value 0.0055). No differences for the other outcomes were noted. Higher risk for non-fatal cardiovascular events persisted after adjustment for age (HR 1.6, 95% CI 1.05-2.47). The only additional covariate that met our selection criteria was hypertension. After adjusting for hypertension, the association between depression and non-fatal cardiovascular outcomes attenuated (HR 1.53, 95% CI 0.99-2.35). In conclusion, a diagnosis of depression in veterans undergoing PVI was associated with increased risk of non-fatal cardiovascular events, mediated by age and hypertension.

Predicting Potential Adverse Events During a Skilled Nursing Facility Stay: A Skilled Nursing Facility Prognosis Score.

OBJECTIVES: To derive a risk prediction score for potential adverse outcomes in older adults transitioning to a skilled nursing facility (SNF) from the hospital. DESIGN: Retrospective analysis. SETTING: Medicare Current Beneficiary Survey (2003-11). PARTICIPANTS: Previously community-dwelling Medicare beneficiaries who were hospitalized and discharged to SNF for postacute care (N=2,043). MEASUREMENTS: Risk factors included demographic characteristics, comorbidities, health status, hospital length of stay, prior SNF stays, SNF size and ownership, treatments received, physical function, and active signs or symptoms at time of SNF admission. The primary outcome was a composite of undesirable outcomes from the patient perspective, including hospital readmission during the SNF stay, long SNF stay (≥100 days), and death during the SNF stay. RESULTS: Of the 2,043 previously community-dwelling beneficiaries hospitalized and discharged to a SNF for post-acute care, 589 (28.8%) experienced one of the three outcomes, with readmission (19.4%) most common, followed by mortality (10.5%) and long SNF stay (3.5%). A risk score including 5 factors (Barthel Index, Charlson-Deyo comorbidity score, hospital length of stay, heart failure diagnosis, presence of an indwelling catheter) demonstrated very good discrimination (C-statistic=0.75), accuracy (Brier score=0.17), and calibration for observed and expected events. CONCLUSION: Older adults frequently experience potentially adverse outcomes in transitions to a SNF from the hospital; this novel score could be used to better match resources with patient risk.

Sex-based differences in veterans with pulmonary hypertension: Results from the veterans affairs-clinical assessment reporting and tracking database.

Women have an increased risk of pulmonary hypertension (PH) but better survival compared to men. Few studies have explored sex-based differences in population-based cohorts with PH. We sought to determine whether sex was associated with hemodynamics and survival in US veterans with PH (mean pulmonary artery pressure [mPAP] ≥ 25 mm Hg) from the Veterans Affairs Clinical Assessment, Reporting, and Tracking database. The relationship between sex and hemodynamics was assessed with multivariable linear mixed modeling. Cox proportional hazards models were used to compare survival by sex for those with PH and precapillary PH (mPAP ≥ 25 mm Hg, pulmonary artery wedge pressure [PAWP] ≤ 15 mm Hg and pulmonary vascular resistance [PVR] > 3 Wood units) respectively. The study population included 15,464 veterans with PH, 516 (3%) of whom were women; 1,942 patients (13%) had precapillary PH, of whom 120 (6%) were women. Among those with PH, women had higher PVR and pulmonary artery pulse pressure, and lower right atrial pressure and PAWP (all p <0.001) compared with men. There were no significant differences in hemodynamics according to sex in veterans with precapillary PH. Women with PH had 18% greater survival compared to men with PH (adjusted HR 0.82, 95% CI 0.69-0.97, p = 0.020). Similarly, women with precapillary PH were 29% more likely to survive as compared to men with PH (adjusted HR 0.71, 95% CI 0.52-0.98, p = 0.040). In conclusion, female veterans with PH have better survival than males despite higher pulmonary afterload.

Thermodilution vs Estimated Fick Cardiac Output Measurement in Clinical Practice: An Analysis of Mortality From the Veterans Affairs Clinical Assessment, Reporting, and Tracking (VA CART) Program and Vanderbilt University.

Importance: Thermodilution (Td) and estimated oxygen uptake Fick (eFick) methods are widely used to measure cardiac output (CO). They are often used interchangeably to make critical clinical decisions, yet few studies have compared these approaches as applied in medical practice. Objectives: To assess agreement between Td and eFick CO and to compare how well these methods predict mortality. Design, Setting, and Participants: This investigation was a retrospective cohort study with up to 1 year of follow-up. The study used data from the Veterans Affairs Clinical Assessment, Reporting, and Tracking (VA CART) program. The findings were corroborated in a cohort of patients cared for at Vanderbilt University, an academic referral center. Participants were more than 15 000 adults who underwent right heart catheterization, including 12 232 in the Veterans Affairs cohort between October 1, 2007, and September 30, 2013, and 3391 in the Vanderbilt cohort between January 1, 1998, and December 31, 2014. Exposures: A single cardiac catheterization was performed on each patient with CO estimated by both Td and eFick methods. Cardiac output was indexed to body surface area (cardiac index [CI]) for all analyses. Main Outcomes and Measures: All-cause mortality over 90 days and 1 year after catheterization. Results: Among 12 232 VA patients (mean [SD] age, 66.4 [9.9] years; 3.3% female) who underwent right heart catheterization in this cohort study, Td and eFick CI estimates correlated modestly (r = 0.65). There was minimal mean difference (eFick minus Td = -0.02 L/min/m2, or -0.4%) but wide 95% limits of agreement between methods (-1.3 to 1.3 L/min/m2, or -50.1% to 49.4%). Estimates differed by greater than 20% for 38.1% of patients. Low Td CI (<2.2 L/min/m2 compared with normal CI of 2.2-4.0 L/min/m2) more strongly predicted mortality than low eFick CI at 90 days (Td hazard ratio [HR], 1.71; 95% CI, 1.47-1.99; χ2 = 49.5 vs eFick HR, 1.42; 95% CI, 1.22-1.64; χ2 = 20.7) and 1 year (Td HR, 1.53; 95% CI, 1.39-1.69; χ2 = 71.5 vs eFick HR, 1.35; 1.22-1.49; χ2 = 35.2). Patients with a normal CI by both methods had 12.3% 1-year mortality. There was no significant additional risk for patients with a normal Td CI but a low eFick CI (12.9%, P = .51), whereas a low Td CI but normal eFick CI was associated with higher mortality (15.4%, P = .001). The results from the Vanderbilt cohort were similar in the context of a more balanced sex distribution (46.6% female). Conclusions and Relevance: There is only modest agreement between Td and eFick CI estimates. Thermodilution CI better predicts mortality and should be favored over eFick in clinical practice.

The Veterans Health Administration's proposal for APRN full-practice authority.

The Veterans Health Administration (VHA) is proposing full-practice authority for advanced practice registered nurses (APRNs) to improve access, care delivery, and patient choice, as well as reduce costs. The authors performed a mixed-methods assessment to obtain the perspectives of administrators and APRNs on the characterization of the APRN workforce and their present practice in the VHA.
