Improving Nurse-Physician Bedside Communication Using a Patient Experience Quality Improvement Pilot Project at an Academic Medical Center.

(2024)

Introduction  Patient experience is a crucial aspect of healthcare delivery, and it encompasses various elements that contribute to a patients perception of the care they receive. Patient satisfaction and patient experience are related but distinct concepts. Patient experience focuses on whether specific aspects of care occurred, while patient satisfaction gauges whether patient expectations were met. It goes beyond mere satisfaction and delves into the broader aspects of how patients interact with the healthcare system and the quality of those interactions, with health plans, doctors, nurses, and staff in various healthcare facilities. Other aspects highly valued by patients include elements such as timely access to care and information, good communication with the healthcare team, and friendly staff. Patient experience can influence both the healthcare and financial outcomes of healthcare facilities. It is well understood that positive patient experiences may lead to better care adherence, improved clinical outcomes, enhanced patient safety, and better care coordination. Payers, both public and private, have recognized the importance of patient experience. Improving patient experience benefits healthcare facilities financially by strengthening customer loyalty, building a positive reputation, increasing referrals, and reducing medical malpractice risk and staff turnover.  Methodology A multidisciplinary retrospective quality improvement initiative was initiated to effectively improve nurse-physician communication and organizational outcomes in several hospital units. Results Using an innovative staff-developed and driven acronym, IMOMW (Im on my way), the study demonstrated significant positive outcomes such as increased Epic documentation (Epic Systems Corporation, Verona, Wisconsin, United States) of physician and nursing rounding by 13%, a 10.5% rise in recommend facility net promoter score (NPS) patient experience survey scores, 13.4% increase in physician and nurse team communication, 5.4% increase in nursing communication, and a 5.3% increase in physician communication. Moreover, pilot units outperformed the control group consisting of medical-surgical units located in newer portions of the hospital. Conclusion This quality improvement study demonstrates improved interdisciplinary nurse-physician communication, Epic documentation, and patient experience scores. Further investigation is necessary to better understand the specific factors and/or processes that influence the sustainability of interventions that improve nurse-physician communication and patient experience.

Immunomodulators for immunocompromised patients hospitalized for COVID-19: a meta-analysis of randomized controlled trials.

(2024)

BACKGROUND: Although immunomodulators have established benefit against the new coronavirus disease (COVID-19) in general, it is uncertain whether such agents improve outcomes without increasing the risk of secondary infections in the specific subgroup of previously immunocompromised patients. We assessed the effect of immunomodulators on outcomes of immunocompromised patients hospitalized for COVID-19. METHODS: The protocol was prospectively registered with PROSPERO (CRD42022335397). MEDLINE, Cochrane Central Register of Controlled Trials and references of relevant articles were searched up to 01-06-2022. Authors of potentially eligible randomized controlled trials were contacted to provide data on immunocompromised patients randomized to immunomodulators vs control (i.e., placebo or standard-of-care). FINDINGS: Eleven randomized controlled trials involving 397 immunocompromised patients hospitalized for COVID-19 were included. Ten trials had low risk of bias. There was no difference between immunocompromised patients randomized to immunomodulators vs control regarding mortality [30/182 (16.5%) vs 41/215 (19.1%); RR 0.93, 95% CI 0.61-1.41; p = 0.74], secondary infections (RR 1.00, 95% CI 0.64-1.58; p = 0.99) and change in World Health Organization ordinal scale from baseline to day 15 (weighed mean difference 0.27, 95% CI -0.09-0.63; p = 0.15). In subgroup analyses including only patients with hematologic malignancy, only trials with low risk of bias, only trials administering IL-6 inhibitors, or only trials administering immunosuppressants, there was no difference between comparators regarding mortality. INTERPRETATION: Immunomodulators, compared to control, were not associated with harmful or beneficial outcomes, including mortality, secondary infections, and change in ordinal scale, when administered to immunocompromised patients hospitalized for COVID-19.

Disrupted routines anticipate musical exploration.

(2024)

Understanding and predicting the emergence and evolution of cultural tastes manifested in consumption patterns is of central interest to social scientists, analysts of culture, and purveyors of content. Prior research suggests that taste preferences relate to personality traits, values, shifts in mood, and immigration destination. Understanding everyday patterns of listening and the function music plays in life has remained elusive, however, despite speculation that musical nostalgia may compensate for local disruption. Using more than one hundred million streams of four million songs by tens of thousands of international listeners from a global music service, we show that breaches in personal routine are systematically associated with personal musical exploration. As people visited new cities and countries, their preferences diversified, converging toward their travel destinations. As people experienced the very different disruptions associated with COVID-19 lockdowns, their preferences diversified further. Personal explorations did not tend to veer toward the global listening average, but away from it, toward distinctive regional musical content. Exposure to novel music explored during periods of routine disruption showed a persistent influence on listeners' future consumption patterns. Across all of these settings, musical preference reflected rather than compensated for life's surprises, leaving a lasting legacy on tastes. We explore the relationship between these findings and global patterns of behavior and cultural consumption.

Efficacy of oral 20-hydroxyecdysone (BIO101), a MAS receptor activator, in adults with severe COVID-19 (COVA): a randomized, placebo-controlled, phase 2/3 trial.

(2024)

BACKGROUND: SARS-CoV-2 binding to ACE2 is potentially associated with severe pneumonia due to COVID-19. The aim of the study was to test whether Mas-receptor activation by 20-hydroxyecdysone (BIO101) could restore the Renin-Angiotensin System equilibrium and limit the frequency of respiratory failure and mortality in adults hospitalized with severe COVID-19. METHODS: Double-blind, randomized, placebo-controlled phase 2/3 trial. Randomization: 1:1 oral BIO101 (350 mg BID) or placebo, up to 28 days or until an endpoint was reached. Primary endpoint: mortality or respiratory failure requiring high-flow oxygen, mechanical ventilation, or extra-corporeal membrane oxygenation. Key secondary endpoint: hospital discharge following recovery (ClinicalTrials.gov Number, NCT04472728). FINDINGS: Due to low recruitment the planned sample size of 310 was not reached and 238 patients were randomized between August 26, 2020 and March 8, 2022. In the modified ITT population (233 patients; 126 BIO101 and 107 placebo), respiratory failure or early death by day 28 was 11.4% lower in the BIO101 (13.5%) than in the placebo (24.3%) group, (p = 0.0426). At day 28, proportions of patients discharged following recovery were 80.1%, and 70.9% in the BIO101 and placebo group respectively, (adjusted difference 11.0%, 95% CI [-0.4%, 22.4%], p = 0.0586). Hazard Ratio for time to death over 90 days: 0.554 (95% CI [0.285, 1.077]), a 44.6% mortality reduction in the BIO101 group (not statistically significant). Treatment emergent adverse events of respiratory failure were more frequent in the placebo group. INTERPRETATION: BIO101 significantly reduced the risk of death or respiratory failure supporting its use in adults hospitalized with severe respiratory symptoms due to COVID-19. FUNDING: Biophytis.

Social network tie functions of social support and social influence and adult smoking abstinence.

(2024)

Adults social network ties serve multiple functions and play prominently in quitting smoking. We examined three types of adults egocentric social networks, including family, friends, and friends online to investigate how two network characteristics with major relevance to health behavior, network size and tie closeness, related to the emotional and confidant support and to pro- and anti-smoking social influence these ties may transmit. We also examine whether the social support and social influence constructs related to smoking abstinence. We utilized baseline and 7-day abstinence survey data from 123 adult current smokers attempting to quit prior to the start of a randomized controlled quit-smoking trial of a social support intervention for quitting smoking on Twitter. To examine study relationships, we estimated Negative Binomial Regression models and Logistic Regression models. For all networks, network size and tie closeness related positively to most of the social support and social influence constructs, with tie closeness related most strongly, especially for online friends. Family pro-smoking social influence related negatively to smoking abstinence, and there were marginally negative relationships for family emotional support and family confidant support. Online friend emotional support had a marginally positive relationship with smoking abstinence. Overall, our findings indicated the importance of the social support and social influence functions of each type of network tie, with larger networks and closer ties related to higher levels of social support and social influence. Moreover, family network pro-smoking social influence may compromise abstinence while emotional support from online friend network ties may reinforce it.

Effectiveness, Safety, and Costs of Thromboprophylaxis with Enoxaparin or Unfractionated Heparin Among Medical Inpatients With Chronic Obstructive Pulmonary Disease or Heart Failure.

(2024)

Background: Chronic obstructive pulmonary disease (COPD) and heart failure (HF) are risk factors for venous thromboembolism (VTE). Enoxaparin and unfractionated heparin (UFH) help prevent hospital-associated VTE, but few studies have compared them in COPD or HF. Objectives: To compare effectiveness, safety, and costs of enoxaparin vs UFH thromboprophylaxis in medical inpatients with COPD or HF. Methods: This retrospective cohort study included adults with COPD or HF from the Premier PINC AI Healthcare Database. Included patients received prophylactic-dose enoxaparin or UFH during a >6-day index hospitalization (the first visit/admission that met selection criteria during the study period) between January 1, 2010, and September 30, 2016. Multivariable regression models assessed independent associations between exposures and outcomes. Hospital costs were adjusted to 2017 US dollars. Patients were followed 90 days postdischarge (readmission period). Results: In the COPD cohort, 114 174 (69%) patients received enoxaparin and 51 011 (31%) received UFH. Among patients with COPD, enoxaparin recipients had 21%, 37%, and 10% lower odds of VTE, major bleeding, and in-hospital mortality during index admission, and 17% and 50% lower odds of major bleeding and heparin-induced thrombocytopenia (HIT) during the readmission period, compared with UFH recipients (all P <.006). In the HF cohort, 58 488 (58%) patients received enoxaparin and 42 726 (42%) received UFH. Enoxaparin recipients had 24% and 10% lower odds of major bleeding and in-hospital mortality during index admission, and 13%, 11%, and 51% lower odds of VTE, major bleeding, and HIT during readmission (all P <.04) compared with UFH recipients. Enoxaparin recipients also had significantly lower total hospital costs during index admission (mean reduction per patient: COPD, 1280;HF,2677) and readmission (COPD, 379;HF,1024). Among inpatients with COPD or HF, thromboprophylaxis with enoxaparin vs UFH was associated with significantly lower odds of bleeding, mortality, and HIT, and with lower hospital costs. Conclusions: This study suggests that thromboprophylaxis with enoxaparin is associated with better outcomes and lower costs among medical inpatients with COPD or HF based on real-world evidence. Our findings underscore the importance of assessing clinical outcomes and side effects when evaluating cost-effectiveness.

Measuring Corporate Tax Rate and Tax Base Avoidance of U.S. Domestic and U.S. Multinational Firms

(2021)

We develop an approach based on publicly available data to decompose and quantify tax avoidance into two separate components: tax rate avoidance and tax base avoidance. Our measures are based on the average statutory tax rate, which accounts for the statutory tax rates across all transactions of a firm. We illustrate and validate our measures using simulation data, the Tax Reform Act of 1986, the Tax Cuts and Jobs Act of 2017, changes in tax rate avoidance and tax base avoidance across time, bonus depreciation time periods, several sample splits of U.S. multinational and domestic firms, differences across industries, and firms operating in tax haven locations. The measures allow regulators and researchers to gain insights into these two conceptually different tax avoidance strategies.

An overview of academic tax accounting research drawing on U.S. multinational taxation

(2020)

Economics-based tax research in accounting draws heavily on the Scholes and Wolfson framework. The framework develops a global approach to tax planning where all parties, all taxes, and all costs are to be considered in effective tax planning. Effective tax planning is distinct from tax minimization as the goal of the former is to maximize the after-tax rate of return. The first empirical applications of the framework followed the passage of the Tax Reform Act of 1986. Taxation of multinationals has long been of interest to accounting (and other) researchers and continues to be of interest. The Tax Cuts and Jobs Act of 2017 changed many tax laws including how the U.S. taxes U.S. multinationals. Research examining the ramifications of this latest Tax Act is already well under way.

A BEHAVIORAL PERSPECTIVE OF SEARCH IN NONPROFIT ORGANIZATIONS: HOW PROGRAMMATIC PERFORMANCE DRIVES FUNDRAISING EFFORTS

(2020)

In this paper, we extend the BTOF to nonprofit organizations. Nonprofits hold both financial and higher-priority nonfinancial programmatic performance goals that relate to program spending directed to fulfill a social mission. We hypothesize that, while financial performance above aspirations decreases fundraising, programmatic performance above aspirations increases fundraising efforts. We also theorize that board size, environmental munificence, and program-generated revenue influence the extent of fundraising as a response to attainment discrepancies. We test our hypotheses using a panel dataset of 12,382 U.S. nonprofits and find support for several of our predictions.

Corporate Tax Avoidance and Debt Costs

(2019)

We use path analysis to investigate how corporate tax avoidance is priced in bond yields and bank loan spreads. We find that approximately one half of the total effect of tax avoidance on bond yields is explained through the negative effect of tax avoidance on future pre-tax cash flow levels and volatility and, to a lesser extent, lower information quality. The effects of these mediating variables are much less pronounced for bank loan spreads. The results of additional cross-sectional analyses indicate that, relative to bond investors, banks are able to reduce information asymmetry problems more effectively, given their access to firms’ private information and greater ability to monitor borrowers.
