Predictors of Success in the Bundled Payments for Care Improvement Program.

BACKGROUND: Hospitals participating in Medicare's Bundled Payments for Care Improvement (BPCI) program were incented to reduce Medicare payments for episodes of care. OBJECTIVE: To identify factors that influenced whether or not hospitals were able to save in the BPCI program, how the cost of different services changed to produce those savings, and if "savers" had lower or decreased quality of care. DESIGN: Retrospective cohort study. PARTICIPANTS: BPCI-participating hospitals. MAIN MEASURES: We designated hospitals that met the program goal of decreasing costs by at least 2% from baseline in average Medicare payments per 90-day episode as "savers." We used regression models to determine condition-level, patient-level, hospital-level, and market-level characteristics associated with savings. KEY RESULTS: In total, 421 hospitals participated in BPCI, resulting in 2974 hospital-condition combinations. Major joint replacement of the lower extremity had the highest proportion of savers (77.6%, average change in payments -$2235) and complex non-cervical spinal fusion had the lowest (22.2%, average change +$8106). Medical conditions had a higher proportion of savers than surgical conditions (11% more likely to save, P=0.001). Conditions that were mostly urgent/emergent had a higher proportion of savers than conditions that were mostly elective (6% more likely to save, P=0.007). Having higher than median costs at baseline was associated with saving (OR: 3.02, P<0.001). Hospitals with more complex patients were less likely to save (OR: 0.77, P=0.003). Savings occurred across both inpatient and post-acute care, and there were no decrements in clinical care associated with being a saver. CONCLUSIONS: Certain conditions may be more amenable than others to saving under bundled payments, and hospitals with high costs at baseline may perform well under programs which use hospitals' own baseline costs to set targets. Findings may have implications for the BPCI-Advanced program and for policymakers seeking to use payment models to drive improvements in care.

Pulmonary vascular resistance determines mortality in end-stage renal disease patients with pulmonary hypertension.

The multifactorial etiology of pulmonary hypertension (PH) in end-stage renal disease (ESRD) includes patients with and without elevated pulmonary vascular resistance (PVR). We explored the prognostic implication of this distinction by evaluating pretransplant ESRD patients who underwent right heart catheterization and echocardiography. Demographics, clinical data, and test results were analyzed. All-cause mortality data were obtained. Median follow-up was 4 years. Of the 150 patients evaluated, echocardiography identified 99 patients (66%) with estimated pulmonary artery (PA) systolic pressure > 36 mm Hg, which correlated poorly with mortality (HR = 1.28, 95% CI 0.72-2.27, P = .387). Right heart catheterization identified 88 (59%) patients with mean PA pressure ≥ 25 mm Hg. Of these, 70 had PVR ≤ 3 Wood units and 18 had PVR > 3 Wood units. Survival analysis demonstrated a significant prognostic effect of an elevated PVR in patients with high mean PA pressures (HR = 2.26, 95% CI 1.07-4.77, P = .03), while patients with high mean PA pressure and normal PVR had equivalent survival to those with normal PA pressure. Despite the high prevalence of PH in ESRD patients, elevated PVR is uncommon and is a determinant of prognosis in patients with PH. Patients with normal PVR had survival equivalent to those with normal PA pressures.

Hemodynamic Predictors of Stabilization When Using Temporary Mechanical Support for Cardiogenic Shock from Acute on Chronic Heart Failure.

Cardiogenic shock from acute on chronic heart failure is a lethal condition that frequently requires temporary mechanical circulatory support devices (tMCS) as a bridge to stabilization, durable support, or heart transplantation. However, there are limited data on methods to optimize use of tMCS in this population. We identified patients who received tMCS devices for cardiogenic shock from acute on chronic heart failure at a single center from August 2016 to July 2020. All the patients had invasive hemodynamic data before and immediately after tMCS placement. We classified patients according to whether they showed stabilization or decompensation with tMCS. We then evaluated hemodynamics pre-tMCS, post-tMCS, and the change in hemodynamics with tMCS (∆-tMCS) and assessed their relationship with clinical outcomes. Among 111 patients who received tMCS, 71 stabilized, and 40 decompensated. Post-tMCS hemodynamics were more likely than were pre-tMCS or ∆-tMCS to predict stabilization. Post-tMCS cardiac index >2.1 (area under the curve: 92.2) and cardiac power index >0.3 (area under the curve: 89.6) were the best predictors of stabilization. Patients who decompensated had increased in-hospital all-cause mortality (hazard ratio 3.06 [1.29 to 7.24], p = 0.011), cardiovascular mortality, and increased hospital and intensive care unit length of stay and were less likely to receive left ventricular assist device or heart transplant (hazard ratio 0.56 [0.36 to 0.88], p = 0.01). In conclusion, among patients with cardiogenic shock from acute on chronic heart failure who received tMCS, post-tMCS cardiac index and cardiac power index were highly predictive of stabilization. Those who decompensated had increased mortality, hospital length of stay, and intensive care unit length of stay and were less likely to receive heart replacement therapy.

Variation in the Use of Targeted Temperature Management for Cardiac Arrest.

Targeted temperature management (TTM) is recommended for patients who do not respond after return of spontaneous circulation after cardiac arrest. However, the degree to which patients with cardiac arrest have access to this therapy on a national level is not known. Understanding hospital- and patient-level factors associated with receipt of TTM could inform interventions to improve access to this treatment among appropriate patients. Therefore, we performed a retrospective analysis using National Inpatient Sample data from 2016 to 2019. We used International Classification of Diseases, Tenth Edition diagnosis and procedure codes to identify adult patients with in-hospital and out-of-hospital cardiac arrest and receipt of TTM. We evaluated patient and hospital factors associated with receiving TTM. We identified 478,419 patients with cardiac arrest. Of those, 4,088 (0.85%) received TTM. Hospital use of TTM was driven by large, nonprofit, urban, teaching hospitals, with less use at other hospital types. There was significant regional variation in TTM capabilities, with the proportion of hospitals providing TTM ranging from >21% in the Mid-Atlantic region to <11% in the East and West South Central and Mountain regions. At the patient level, age >74 years (odds ratio [OR] 0.54, p <0.001), female gender (OR 0.89, p >0.001), and Hispanic ethnicity (OR 0.74, p <0.001) were all associated with decreased odds of receiving TTM. Patients with Medicare (OR 0.75, p <0.001) and Medicaid (OR 0.89, p = 0.027) were less likely than patients with private insurance to receive TTM. Part of these differences was driven by inequitable access to TTM-capable hospitals. In conclusion, TTM is rarely used after cardiac arrest. Hospital use of TTM is predominately limited to a subset of academic hospitals with substantial regional variation. Older age, female gender, Hispanic ethnicity, and Medicare or Medicaid insurance are all associated with a decreased likelihood of receiving TTM.

The Association of the UNOS Heart Allocation Policy Change With Transplant and Left Ventricular Assist Device Access and Outcomes.

In October 2018, the allocation policy for adult orthotopic heart transplant (OHTx) in the United States was changed, with the goal of reducing waitlist mortality and providing broader sharing of donor organs within the United States. This study aimed to assess the association of this policy change with changes in access to OHTx versus left ventricular assist devices (LVADs), overall and in key sociodemographic subgroups, in the United States from 2016 to 2019. We identified all patients receiving OHTx or LVAD between 2016 and 2019 using the National Inpatient Sample. Controlling for medical co-morbidities, prepolicy trends, and within-hospital-year effects, we fit a dynamic logistic regression model to evaluate patient and hospital factors associated with receiving OHTx versus LVAD before versus after policy change. We also examined the frequency of temporary mechanical circulatory support in the same fashion. We identified 2,264 patients who received OHTx and 3,157 who received LVADs during the study period. In its first year of implementation, the United Network for Organ Sharing policy change of 2018 was associated with no overall change utilization of OHTx versus LVAD. In OHTx recipients, the frequency of use of temporary mechanical circulatory support changed from 15.6% in the before period to 42.6% in the after period (p <0.001). Although the policy change was associated with differences in the odds of receiving an OHTx versus LVAD between different regions of the country, there were no significant changes based on age, gender, race/ethnicity, insurance status, or rurality. In conclusion, the United Network for Organ Sharing policy change on access to OHTx was associated with no overall change in OHTx versus LVAD use in its first year of implementation although we observed small changes in relative odds of transplant based on rurality. Shifts in regional allocation were not significant overall, although certain regions appeared to have a relative increase in their use of OHTx.

Vibrational spectroscopy of N-methyliminodiacetic acid (MIDA)-protected boronate ester: examination of the B-N dative bond.

N-methyliminodiacetic acid (MIDA)-protected boronate esters are a new class of reagents that offer great promise in iterative Suzuki-Miyaura cross-coupling reactions. Compared to earlier reagents, MIDA esters are easily handled and are benchtop stable under air indefinitely. The success of this new species is tied to its unique molecular architecture. Compared to the simpler B-N containing molecules ammonia borane and trimethylamine borane, MIDA esters are much larger, and the sp(3) hybridized boron atom is secured by two five membered rings, making this molecular class stable for spectroscopic study. Here, we present infrared, Raman, and surface enhanced Raman (SERS) spectra of methylboronic acid MIDA ester. Comparisons of the spectroscopic results to those from electronic structure calculations suggest that the B-N stretching mode in this molecule lies in the range 560-650 cm(-1), making it among the lowest energy vibrations observed to date that can be primarily attributed to B-N stretching.

Characteristics of Inpatient Units Associated With Sustained Hand Hygiene Compliance.

OBJECTIVES: Following institution of a hand hygiene (HH) program at an academic medical center, HH compliance increased from 58% to 92% for 3 years. Some inpatient units modeled early, sustained increases, and others exhibited protracted improvement rates. We examined the association between patterns of HH compliance improvement and unit characteristics. METHODS: Adult inpatient units (N = 35) were categorized into the following three tiers based on their pattern of HH compliance: early adopters, nonsustained and late adopters, and laggards. Unit-based culture measures were collected, including nursing practice environment scores (National Database of Nursing Quality Indicators [NDNQI]), patient rated quality and teamwork (Hospital Consumer Assessment of Healthcare Provider and Systems), patient complaint rates, case mix index, staff turnover rates, and patient volume. Associations between variables and the binary outcome of laggard (n = 18) versus nonlaggard (n = 17) were tested using a Mann-Whitney U test. Multivariate analysis was performed using an ordinal regression model. RESULTS: In direct comparison, laggard units had clinically relevant differences in NDNQI scores, Hospital Consumer Assessment of Healthcare Provider and Systems scores, case mix index, patient complaints, patient volume, and staff turnover. The results were not statistically significant. In the multivariate model, the predictor variables explained a significant proportion of the variability associated with laggard status, (R2 = 0.35, P = 0.0481) and identified NDNQI scores and patient complaints as statistically significant. CONCLUSIONS: Uptake of an HH program was associated with factors related to a unit's safety culture. In particular, NDNQI scores and patient complaint rates might be used to assist in identifying units that may require additional attention during implementation of an HH quality improvement program.

Perioperative care of the geriatric patient for noncardiac surgery.

Adults age 65 and over are the fastest growing segment of the population in the United States and around the world. As the size of this population expands, the number of older adults referred for surgical procedures will continue to increase. Due to the physiologic changes of aging and the increased frequency of comorbidities, older adults are at increased risk for adverse outcomes, and perioperative care is inherently more complex than in younger individuals. In this review, we discuss the physiologic changes of aging relevant to the surgical patient, comprehensive preoperative assessment, and postoperative management of common complications in older adults in order to promote optimal clinical outcomes both perioperatively and long-term.

Heart Failure and the Affordable Care Act: Past, Present, and Future.

The Affordable Care Act (ACA) and other major health care legislative acts have had an important impact on the care of heart failure patients in the United States. The main effects of the ACA include regulation of the health insurance industry, expansion of access to health care, and health care delivery system reform, which included the creation of several alternative payment models. Particular components of the ACA, such as the elimination of annual and lifetime caps on spending, Medicaid expansion, and the individual and employer mandate, could have positive effects for heart failure patients. However, the benefits of value-based and alternative payment models such as the Hospital Readmissions Reduction Program and bundled payment programs for heart failure outcomes are less clear, and controversy exists regarding whether some of these programs may even worsen outcomes. As the population ages and the prevalence of heart failure continues to rise, this syndrome will likely remain a key clinical focus for policymakers. Therefore, heart failure clinicians should be aware of how legislation affects clinical practice and be prepared to adapt to continued changes in health policy.
