Serum neurofilament light chain as a prognostic marker of all-cause mortality in a national sample of US adults.

Neurofilament light chain (NfL) is a neuron-specific structural protein released into the extracellular space, including body fluids, upon neuroaxonal damage. Despite evidence of a link in neurological disorders, few studies have examined the association of serum NfL with mortality in population-based studies. Data from the National Health and Nutrition Survey were utilized including 2,071 Non-Hispanic White, Non-Hispanic Black and Hispanic adult participants and adult participants of other ethnic groups (20-85 years) with serum NfL measurements who were followed for ≤ 6 years till 2019. We tested the association of serum NfL with mortality in the overall population and stratified by sex with the addition of potential interactive and mediating effects of cardio-metabolic risk factors and nutritional biomarkers. Elevated serum NfL levels (above median group) were associated with mortality risk compared to the below median NfL group in the overall sample (P = 0.010), with trends observed within each sex group (P < 0.10). When examining Loge NfL as a continuum, one standard deviation of Loge NfL was associated with an increased mortality risk (HR = 1.88, 95% CI 1.60-2.20, P < 0.001) in the reduced model adjusted for age, sex, race, and poverty income ratio; a finding only slightly attenuated with the adjustment of lifestyle and health-related factors. Four-way decomposition indicated that there was, among others, mediated interaction between NfL and HbA1c and a pure inconsistent mediation with 25(OH)D3 in predicting all-cause mortality, in models adjusted for all other covariates. Furthermore, urinary albumin-to-creatinine ratio interacted synergistically with NfL in relation to mortality risk both on the additive and multiplicative scales. These data indicate that elevated serum NfL levels were associated with all-cause mortality in a nationally representative sample of US adults.

Healthcare Worker Mental Health After the Initial Peak of the COVID-19 Pandemic: a US Medical Center Cross-Sectional Survey.

BACKGROUND: There is a paucity of data on the mental health impact of the Coronavirus disease 2019 (COVID-19) pandemic on United States (US) healthcare workers (HCWs) after the first surge in the spring of 2020. OBJECTIVE: To determine the impact of the pandemic on HCWs, and the relationship between HCW mental health and demographics, occupational factors, and COVID-19 concerns. DESIGN: Cross-sectional survey in an urban medical center (September-November 2020) in Baltimore, MD, in the United States. PARTICIPANTS: A total of 605 HCWs (physicians, nurse practitioners, nurses, physician assistants, patient care technicians, respiratory therapists, social workers, mental health therapists, and case managers). MAIN MEASURES: Measures of mental health (Patient Health Questionnaire-2, Generalized Anxiety Disorder-7, PROMIS Sleep Disturbance 4a, Impact of Event Scale-Revised, Maslach Burnout Inventory-2 item, Connor-Davidson Resilience Scale-2 item), demographics, occupational factors, and COVID-19 related concerns. KEY RESULTS: Fifty-two percent of 1198 HCWs responded to the survey and 14.2% reported depression, 43.1% mild or higher anxiety, 31.6% sleep disturbance, 22.3% posttraumatic stress symptoms, 21.6% depersonalization, 46.0% emotional exhaustion, and 23.1% lower resilience. Relative to HCWs providing in-person care to COVID-19 infected patients none of their working days, those doing so all or most days were more likely to experience worse depression (adjusted odds ratio, 3.9; 95% CI, 1.3-11.7), anxiety (aOR, 3.0; 95% CI, 1.4-6.3), possible PTSD symptoms (aOR, 2.6; 95% CI, 1.1-5.8), and higher burnout (aOR, 2.6; 95% CI, 1.1-6.0). Worse mental health in several domains was associated with higher health fear (aORs ranged from 2.2 to 5.0), job stressors (aORs ranged from 1.9 to 4.0), perceived social stigma/avoidance (aORs ranged from 1.8 to 2.9), and workplace safety concerns (aORs ranged from 1.8 to 2.8). CONCLUSIONS: US HCWs experienced significant mental health symptoms eight months into the pandemic. More time spent providing in-person care to COVID-19-infected patients and greater COVID-19-related concerns were consistently associated with worse mental health.

Adaptability on Shifting Ground: a Rapid Qualitative Assessment of Multi-institutional Inpatient Surge Planning and Workforce Deployment During the COVID-19 Pandemic.

BACKGROUND: During the initial wave of COVID-19 hospitalizations, care delivery and workforce adaptations were rapidly implemented. In response to subsequent surges of patients, institutions have deployed, modified, and/or discontinued their workforce plans. OBJECTIVE: Using rapid qualitative methods, we sought to explore hospitalists' experiences with workforce deployment, types of clinicians deployed, and challenges encountered with subsequent iterations of surge planning during the COVID-19 pandemic across a collaborative of hospital medicine groups. APPROACH: Using rapid qualitative methods, focus groups were conducted in partnership with the Hospital Medicine Reengineering Network (HOMERuN). We interviewed physicians, advanced practice providers (APP), and physician researchers about (1) ongoing adaptations to the workforce as a result of the COVID-19 pandemic, (2) current struggles with workforce planning, and (3) evolution of workforce planning. KEY RESULTS: We conducted five focus groups with 33 individuals from 24 institutions, representing 52% of HOMERuN sites. A variety of adaptations was described by participants, some common across institutions and others specific to the institution's location and context. Adaptations implemented shifted from the first waves of COVID patients to subsequent waves. Three global themes also emerged: (1) adaptability and comfort with dynamic change, (2) the importance of the unique hospitalist skillset for effective surge planning and redeployment, and (3) the lack of universal solutions. CONCLUSIONS: Hospital workforce adaptations to the COVID pandemic continued to evolve. While few approaches were universally effective in managing surges of patients, and successful adaptations were highly context dependent, the ability to navigate a complex system, adaptability, and comfort in a chaotic, dynamic environment were themes considered most critical to successful surge management. However, resource constraints and sustained high workload levels raised issues of burnout.

Sex Differences in Patterns of Sleep Disorders Among Hospitalizations With Parkinson's Disease: 2004-2014 Nationwide Inpatient Sample.

OBJECTIVE: This study aimed to examine patterns of sleep disorders among hospitalized adults 65 years and older as related to Parkinson's disease (PD) status and to evaluate sex differences in the associations between PD with sleep disorders. METHODS: A cross-sectional study was conducted using 19,075,169 hospital discharge records (8,169,503 men and 10,905,666 women) from the 2004-2014 Nationwide Inpatient Sample databases. PD and sleep disorder diagnoses were identified based on International Classification of Diseases, Ninth Revision, Clinical Modification coding. Logistic regression models were constructed for each sleep disorder as a correlate of PD status; adjusted odds ratios (aOR) with their 95% confidence intervals (CIs) were calculated taking into account patient and hospital characteristics. RESULTS: Period prevalences of PD and sleep disorder were estimated to be 2.1% and 8.1%, respectively. Most sleep disorder types, with the exception of sleep-related breathing disorders, were positively associated with PD diagnosis. Statistically significant interactions by sex were noted for associations of insomnia (men: aOR = 1.29, 95% CI = 1.24-1.36; women: aOR = 1.17, 95% CI = 1.12-1.22), parasomnia (men: aOR = 3.74, 95% CI = 3.44-4.07; women: aOR = 2.69, 95% CI = 2.44-2.96), sleep-related movement disorder (men: aOR = 1.09, 95% CI = 1.07-1.11; women: aOR = 1.22, 95% CI = 1.20-1.25), and any sleep disorder (men: aOR = 1.06, 95% CI = 1.05-1.08; women: aOR = 1.15, 95% CI = 1.13-1.17) with PD status. CONCLUSIONS: Overall, hospitalized men are more likely to experience PD with insomnia or parasomnia, whereas hospitalized women are more likely to experience PD with sleep-related movement disorder or any sleep disorder. Prospective cohort studies are needed to replicate these cross-sectional findings.

Bracing for the Wave: a Multi-Institutional Survey Analysis of Inpatient Workforce Adaptations in the First Phase of COVID-19.

BACKGROUND: Medical centers across the country have had to rapidly adapt clinician staffing strategies to accommodate large influxes of patients with the coronavirus disease 2019 (COVID-19). OBJECTIVE: We sought to understand the adaptations and staffing strategies that US academic medical centers employed in the inpatient setting early in the spread of COVID-19, and to assess whether those changes were sustained during the first phase of the pandemic. DESIGN: Cross-sectional survey assessing organization-level, team-level, and clinician-level inpatient workforce adaptations. PARTICIPANTS: Hospital medicine leadership at 27 academic medical centers in the USA. KEY RESULTS: Twenty-seven of 36 centers responded to the survey (75%). Widespread practices included frequent staffing reassessment, organization-level changes such as geographic cohorting and redeployment of non-hospitalists, and exempting high-risk healthcare workers from direct care of patients with COVID-19. Several practices were implemented but discontinued, such as reduction of non-essential services, indicating that they were less sustainable for large centers. CONCLUSION: These findings provide guidance for inpatient leaders seeking to identify sustainable practices for COVID-19 inpatient workforce planning.

Regional variation in outcomes and healthcare resources utilization in, emergency department visits for syncope.

BACKGROUND: Management of patients with syncope lacks standardization. We sought to assess regional variation in hospitalization rates and resource utilization of patients with syncope. METHODS: We identified adults with syncope using the Nationwide Emergency Department Sample from years 2006 to 2014. Demographics and comorbidity characteristics were compared across geographic regions in the US. Multiple regression was conducted to compare outcomes. RESULTS: 9,132,176 adults presented with syncope. Syncope in the Northeast (n = 1,831,889) accounted for 20.1% of visits; 22.6% in the Midwest (n = 2,060,940), 38.5% in the South (n = 3,527,814) and 18.7% in the West (n = 1,711,533). Mean age was 56 years with 57.7% being female. The Northeast had the highest risk-adjusted hospitalization rate (24.5%) followed by the South (18.6%, ORadj 0.58; 95% CI 0.52-0.65, p < 0.001), the Midwest (17.2%, ORadj 0.51; 95% CI 0.46-0.58, p < 0.001) and West (15.8%, ORadj 0.45; 95% CI 0.39-0.51, p < 0.001). Risk-adjusted rates of syncope hospitalizations significantly declined from 25.8% (95% CI 24.8%-26.7%) in 2006 to 11.7% (95% CI 11.0%-12.5%) in 2014 (Ptrend < 0.001). The Northeast had the lowest risk-adjusted ED (Emergency Department) service charges per visit ($3320) followed by the Midwest ($4675, IRRadj 1.41; 95% CI 1.30-1.52, p < 0.001), the West ($4814, IRRadj 1.45; 95% CI 1.31-1.60, p < 0.001) and South ($4969, IRRadj 1.50; 95% CI 1.38-1.62, p < 0.001). Service charges increased from $3047/visit (95% CI $2912-$3182) in 2006 to $6267/visit (95% CI $5947-$6586) in 2014 (Ptrend < 0.001). CONCLUSIONS: Significant regional variability in hospitalization rates and ED service charges exist among patients with syncope. Standardizing practices may be needed to reduce variability.

Nationwide study of therapeutic plasma exchange vs intravenous immunoglobulin in Guillain-Barré syndrome.

BACKGROUND: We compared outcomes of therapeutic plasma exchange (TPE) vs intravenous immunoglobulin (IVIG) among hospitalized patients diagnosed with Guillain-Barré syndrome (GBS). METHODS: In a retrospective cohort study of 6642 records (2637 TPE and 4005 IVIG) from the 2002-2014 Nationwide Inpatient Sample, treatment type was examined as predictor of length of stay, total charges, and in-hospital death, with regression modeling using risk adjustment and propensity scoring to control for confounders. RESULTS: Compared with those receiving IVIG, patients who underwent TPE experienced prolonged hospitalization by approximately 7.5 days, greater hospitalization costs by approximately $46,000, and increased in-hospital death with an odds ratio of 2.78. Results did not change after controlling for confounders through risk adjustment, propensity score adjustment, or matching. CONCLUSIONS: TPE may be associated with poorer healthcare utilization outcomes vs IVIG, although confounding by indication could not be ascertained.

The patient-centered oncology care on health care utilization and cost: A systematic review and meta-analysis.

BACKGROUND: Optimal cancer care entails coordination among multiple providers and continued follow-up and surveillance over time. The patient-centered care brings opportunities to improve the delivery of cancer care. The adoption of patient-centered oncology care (PCOC) is in its infancy. Evidence synthesis on the model's effectiveness is scant. PURPOSES: This is the first systemic review and meta-analysis on associations of PCOC with cancer patients' adverse health care utilization, cost, patient satisfaction, and quality of care. METHODS: Our study was guided by the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analyses) framework. Quality appraisal was performed using Downs and Black's quality checklist. Study-level effect sizes of adverse health care utilization were computed using Cohen's d and summarized using forest plots. Funnel plots were constructed to examine publication bias. RESULTS: Of 334 studies that were reviewed, 10 met eligibility criteria and were included into the final analysis. Many included studies implemented almost all six of patient-centered care core attributes, plus three additional attributes that specifically addressed cancer patients' needs, including triage pathways, standardized and evidence-based symptom management, as well as support patient navigation. PCOC patients had lower utilization of inpatient care (standardized means difference [SMD] = -0.027, p = .049). Overall positive effect of PCOC on emergency department use was small and not significant (SMD = -0.023, p = .103). With regard to cost and quality of care, our narrative summaries showed an overall positive direction, though we found limitations in individual study quality that precluded a meta-analysis. PUBLIC IMPLICATION: The results showed that it is possible to utilize patient-centered model to support best practice of cancer care. Early evidence shows that the PCOC model has potential to improve health care utilization, cost, and quality of care, but limited numbers of included articles and heterogeneity of those studies implied that more rigorous research is expected to further investigate the model's effects.

Factors Associated with Timing and Adverse Outcomes in Patients with Biliary Atresia Undergoing Kasai Hepatoportoenterostomy.

OBJECTIVE: To assess factors associated with timing of hepatoportoenterostomy (HPE) and adverse perioperative outcomes in patients with biliary atresia in the US. STUDY DESIGN: We examined hospitalizations in infants aged <1 year using the National Inpatient Sample database for 2000-2011. We identified cases using the International Classification of Diseases, Ninth Revision, Clinical Modification codes for biliary atresia and HPE. Multivariable logistic regression models were used to examine association between select factors and age at HPE, as well as adverse perioperative outcomes. RESULTS: Our analysis of 1243 biliary atresia hospitalizations showed that only 37.7% of patients had HPE in the first 60 days of life. Patients who underwent HPE after 60 days of age were uninsured, were more likely to be black (aOR, 4.22; 95% CI, 1.49-11.95), less likely to be admitted at a teaching hospital (aOR, 0.27; 95% CI 0.10-0.79), and less likely to have a concomitant congenital malformation (aOR, 0.49; 95% CI 0.25-0.98). Patients with delayed age at HPE incurred significantly higher hospital costs ($57 914 vs $34 074; P = .026). Delayed age at HPE and weekend admission were independently associated with increased odds of adverse perioperative outcome (aOR, 1.09; 95% CI, 1.01-3.02 and 3.98; 95% CI, 1.67-9.46, respectively). CONCLUSION: Current outcomes in patients with biliary atresia in the United States are suboptimal and result in higher costs. The specific factors associated with delayed care are further evidence that universal health care and screening are needed for all infants, along with systematic referral of potential patients with biliary atresia to specialized health centers.

Management of Cocaine-Induced Myocardial Infarction: 4-Year Experience at an Urban Medical Center.

OBJECTIVES: In 2008, the American Heart Association and the American College of Cardiology released guidelines for the management of cocaine-induced myocardial infarction (CIMI). We hypothesized that CIMI patients are likely to receive less invasive and more conservative management than patients with MI without history of cocaine use. METHODS: We conducted a retrospective analysis on patients younger than 65 years presenting with acute MI between April 1, 2008 and December 31, 2012. Patients were classified as cocaine-negative MI or CIMI based on either urine toxicology results or self-reported cocaine use. Categorical and continuous variables were compared using χ(2) or t test as appropriate. The primary outcome was cardiac catheterization or stress testing. The secondary outcome was a 30-day readmission rate for major adverse cardiovascular events. Multiple logistic regression models calculated odds ratios (ORs) for the primary outcomes adjusting for patient demographics and comorbidities. RESULTS: Of 378 MI patients, 4.2 % had CIMI. CIMI patients were younger (50 vs 54 years; P < 0.01) predominantly African American (56% vs 16%, P < 0.01), and mostly active smokers (88% vs 58%, P = 0.02). They were more likely to receive stress testing (adjusted OR 3.61, 95% confidence interval 1.04-12.53) and less likely to undergo cardiac catheterization (adjusted OR 0.12, 95% confidence interval 0.03-0.45). The 30-day readmission rate for major adverse cardiovascular events was higher in CIMI compared with cocaine-negative MI patients (38% vs 13%; P = 0.03). CONCLUSIONS: The use of cocaine in patients presenting with acute MI appears to impact management decisions of providers. Patient-centered postdischarge arrangements need better coordination for this patient group to optimize their follow-up care.

Pulmonary artery catheter receipt among cardiac surgery patients from the national inpatient sample (1999-2019): Prevalence, predictors and hospitalization charges.

Despite limited evidence to support its efficacy, use of pulmonary artery catheter (PAC), a relatively expensive medical device, for monitoring clinical status and guiding therapeutic interventions, has become standard of care in many settings, and especially during and after cardiac surgery. We examined the prevalence and predictors of PAC use and its association with hospitalization charges among cardiac surgery patients generally and for each selected subgroup of high-risk or complex surgical procedures. We conducted an analysis on 1,442,528 records from the National Inpatient Sample (1999-2019) that included cardiac surgery patients ≥18 years of age. Subgroups were categorized based on the presence of specific disorders like tricuspid or mitral valve disease, pulmonary hypertension, heart failure, or cardiac surgery combinations. Multivariable regression models were constructed to assess predictors of PAC use as well as PAC use as a predictor of loge hospitalization charges controlling for patient and hospital characteristics. Based on International Classification of Diseases procedure codes, PAC use was prevalent among 7.15 % of cardiac surgery hospitalizations, and hospitalization charges were estimated at $191,345, with no differences according to PAC use. Overall, being female, having Charlson comorbidity index (CCI) > 0, and non-payer (versus Medicare) status were independently associated with PAC use. Among the subgroup with the selected conditions, being female, having CCI>0, and being a Medicaid (versus Medicare) recipient were independently associated with PAC use, whereas elective admission was inversely related to PAC use. Among the subgroup without the selected conditions, having a CCI >0, elective admission, and non-payer (vs. Medicare) status were independently associated with PAC use. PAC use was not independently related to hospitalization charges overall or among subgroups. In conclusion, approximately 7 % of cardiac surgery hospitalizations received a PAC, with no differences in charges according to PAC use and disparities in PAC use driven by sex, elective admission, CCI and health insurance status. Large randomized trials are required to characterize the safety, efficacy, and cost-effectiveness of PAC use among distinct groups of patients undergoing cardiac surgery.

Association of pulmonary artery catheter with in-hospital outcomes after cardiac surgery in the United States: National Inpatient Sample 1999-2019.

To examine associations of pulmonary artery catheter (PAC) use with in-hospital death and hospital length of stay (days) overall and within subgroups of hospitalized cardiac surgery patients. Secondary analyses of 1999-2019 National Inpatient Sample data were performed using 969,034 records (68% male, mean age: 65 years) representing adult cardiac surgery patients in the United States. A subgroup of 323,929 records corresponded to patients with congestive heart failure, pulmonary hypertension, mitral/tricuspid valve disease and/or combined surgeries. We evaluated PAC in relation to clinical outcomes using regression and targeted maximum likelihood estimation (TMLE). Hospitalized cardiac surgery patients experienced more in-hospital deaths and longer stays if they had ≥ 1 subgroup characteristics. For risk-adjusted models, in-hospital deaths were similar among recipients and non-recipients of PAC (odds ratio [OR] 1.04, 95% confidence interval [CI] 0.96, 1.12), although PAC was associated with more in-hospital deaths among the subgroup with congestive heart failure (OR 1.14, 95% CI 1.03, 1.26). PAC recipients experienced shorter stays than non-recipients (ß = - 0.40, 95% CI - 0.64, - 0.15), with variations by subgroup. We obtained comparable results using TMLE. In this retrospective cohort study, PAC was associated with shorter stays and similar in-hospital death rates among cardiac surgery patients. Worse clinical outcomes associated with PAC were observed only among patients with congestive heart failure. Prospective cohort studies and randomized controlled trials are needed to confirm and extend these preliminary findings.

Outcomes of remission induction therapy for ANCA-associated vasculitis in the elderly.

OBJECTIVE: Treatment regimens combining glucocorticoids with cyclophosphamide or rituximab or both are used to induce remission in ANCA-associated glomerulonephritis (ANCA-GN). There is a paucity of data on the efficacy and safety of these regimens in elderly patients with ANCA-GN. This study aimed to examine outcomes and adverse events in elderly AAV patients with three induction regimens: cyclophosphamide (CYC), cyclophosphamide and rituximab (CYC + RTX), and rituximab (RTX). METHODS: This single-center retrospective cohort study included patients 60 years and older diagnosed with ANCA-GN. Baseline characteristics and outcomes across several clinical parameters were recorded and compared for significance using Kruskal-Wallis test, Chi-squared test, Fisher exact test, univariate, and multivariate logistic regression as appropriate. Cox proportional hazard regression model was used for survival analysis. RESULTS: Seventy-five patients were included. The mean (SD) age at diagnosis was 70 (± 6) years. The mean (SD) follow-up duration was 5.17 (± 3.47) years. Remission induction therapy with glucocorticoids plus CYC was used in 25 patients, glucocorticoids plus CYC and RTX in 12 patients, and glucocorticoids plus RTX in 38 patients. RTX-treated patients had a higher baseline estimated glomerular filtration ratio (eGFR) (p = 0.00009). High remission rates were achieved in all groups (100% vs. 100% vs. 94.6% respectively, p = 0.368). The incidence of end-stage renal disease (ESRD) at one year was 8% among all groups (p = 0.999). There was no difference in the number of infections requiring hospitalization (p = 0.822), but a statistical difference in leukopenia was noted (32% vs. 25% vs. 3% respectively, p = 0.005). The use of RTX only was associated with reduced leukopenia (aOR = 0.1, 95% CI = 0.005-0.8) after adjusting for other variables. CONCLUSIONS: CYC, CYC + RTX, and RTX are equally effective for remission induction in elderly patients with ANCA-GN. Induction therapy with RTX only was associated with a lower risk of leukopenia compared to CYC-containing regimens. Infections requiring hospitalization were similar among all groups. End-stage kidney disease at one year was comparable among the 3 groups. Key Points • Cyclophosphamide, Rituximab, and Cyclophosphamide+Rituximab are equally effective in remission induction in elderly patients with ANCA glomerulonephritis. • The use of Rituximab only was associated with a lower risk of bone marrow suppression compared to Cyclophosphamide only. • More information is needed on the comparative safety of induction therapy strategies in elderly ANCA glomerulonephritis patients.

Prevalence of Workplace Violence and Effects of De-escalation Training Among Hospitalists: A Pilot Study.

Introduction: Workplace violence (WPV) is increasing in healthcare and negatively impacts healthcare worker outcomes. De-escalation training for healthcare workers is recommended to reduce WPV from patients and visitors. Hospitalists may be at high risk for WPV, but the magnitude of WPV and the impact of de-escalation training among hospitalists is not known. Methods: We investigated the baseline prevalence of WPV experienced by 37 hospitalists at a single center. After an in-person de-escalation training, we measured hospitalists' self-reported "Confidence in Coping with Patient Aggression" using a validated scale (score range 10-110). Results: In the 12 months before de-escalation training, 86.5% of participants reported at least one form of WPV: 83.8% verbal abuse, 29.7% racial abuse, 18.9% physical violence, and 16.2% sexual abuse. The mean confidence score increased significantly from pre-training (43.2) to immediately after training (68.5) and remained significantly elevated at three months (57.2), six months (60.2), and after 12 months (59.9) (all P < 0.05; Ptrend <0.05). Conclusion: Hospitalists are at high risk for WPV. Structured in-person de-escalation training may provide the sustained ability for hospitalists to cope with WPV.

Feasibility of and Experience with Free State Funded Telehealth Based Patient Self-referral for COVID-19 Monoclonal Antibody Therapy.

BACKGROUND: Monoclonal antibody (mAb) treatment for COVID-19 has been underutilized due to logistical challenges, lack of access and variable treatment awareness among patients and healthcare professionals. The use of telehealth during the pandemic provides an opportunity to increase access to COVID-19 care. METHODS: This is a single-center descriptive study of telehealth-based patient self-referral for mAb therapy between March 1, 2021, to October 31, 2021 at Baltimore Convention Center Field Hospital (BCCFH). RESULTS: Among the 1001 self-referral patients, the mean age was 47, and most were female (57%) white (66%), and had a primary care provider (62%). During the study period, self-referrals increased from 14 per month in March to 427 in October resulting in a 30-fold increase. About 57% of self-referred patients received a telehealth visit, and of those 82% of patients received mAb infusion therapy. The median time from self-referral to onsite infusion was 2 days (1-3 IQR). DISCUSSION: Our study shows the integration of telehealth with a self-referral process improved access to mAb infusion. A high proportion of self-referrals were appropriate and led to timely treatment. This approach helped those without traditional avenues for care and avoided potential delay for patients seeking referral from their PCPs.

Interrupted Time-Series Analysis of Stereotactic Radiosurgery for Brain Metastases Before and After the Affordable Care Act.

The 2010 Patient Protection and Affordable Care Act was aimed at reducing healthcare costs, improving healthcare quality, and expanding health insurance coverage among uninsured individuals in the United States. We examined trends in the utilization of radiation therapies and stereotactic radiosurgery before and after its implementation among U.S. adults hospitalized with brain metastasis. Interrupted time-series analyses of data on 383,934 Nationwide Inpatient Sample hospitalizations (2005-2010 and 2011-2013) were performed, whereby yearly and quarterly cross-sectional data were evaluated and Affordable Care Act implementation was considered the main exposure variable, stratifying by patient and hospital characteristics. Overall, we observed a declining trend in radiation therapy over time, with an upward shift post-Affordable Care Act. A downward shift in radiation therapy post-Affordable Care Act was observed among Northeastern and rural hospitals, whereas an upward shift was noted among specific patient (females, 18-39 or ≥ 65 years of age, Charlson Comorbidity Index (CCI) ≥10, non-elective admissions, Medicare, self-pay, no pay or other insurance) and hospital (Midwestern, Western, non-teaching urban) subgroups. Stereotactic radiosurgery utilization among recipients of radiation therapy increased over time among Hispanics, elective admissions, and rural hospitals, whereas post-Affordable Care Act was associated with increased stereotactic radiosurgery among African-Americans and non-elective admissions and decreased stereotactic radiosurgery among elective admissions, and rural hospitals. Whereas hospitalized adults in the United States utilized less radiation therapy over the nine-year period, utilization of radiation therapy, in general, and stereotactic radiosurgery, in particular, were not consistent among distinct subgroups defined by patient and hospital characteristics, with some traditionally underserved populations more likely to receive healthcare services post-Affordable Care Act. The Affordable Care Act may be helpful at closing the gap in access to technological advances such as stereotactic radiosurgery for treating brain metastases.

Recruitment, Readiness, and Retention of Providers at a Field Hospital During the Pandemic.

In response to the coronavirus disease (COVID-19) pandemic, the State of Maryland established a 250-bed emergency response field hospital at the Baltimore Convention Center to support the existing health care infrastructure. To operationalize this hospital with 65 full-time equivalent clinicians in less than 4 weeks, more than 300 applications were reviewed, 186 candidates were interviewed, and 159 clinicians were credentialed and onboarded. The key steps to achieve this undertaking involved employing multidisciplinary teams with experienced personnel, mass outreach, streamlined candidate tracking, pre-interview screening, utilizing all available expertise, expedited credentialing, and focused onboarding. To ensure staff preparedness, the leadership developed innovative team models, applied principles of effective team building, and provided "just in time" training on COVID-19 and non-COVID-19-related topics to the staff. The leadership focused on staff safety and well-being, offered appropriate financial remuneration, and provided leadership opportunities that allowed retention of staff.

Hospitalization outcomes among brain metastasis patients receiving radiation therapy with or without stereotactic radiosurgery from the 2005-2014 Nationwide Inpatient Sample.

The purpose of this study was to compare hospitalization outcomes among US inpatients with brain metastases who received stereotactic radiosurgery (SRS) and/or non-SRS radiation therapies without neurosurgical intervention. A cross-sectional study was conducted whereby existing data on 35,199 hospitalization records (non-SRS alone: 32,981; SRS alone: 1035; SRS + non-SRS: 1183) from 2005 to 2014 Nationwide Inpatient Sample were analyzed. Targeted maximum likelihood estimation and Super Learner algorithms were applied to estimate average treatment effects (ATE), marginal odds ratios (MOR) and causal risk ratio (CRR) for three distinct types of radiation therapy in relation to hospitalization outcomes, including length of stay (' ≥ 7 days' vs. ' < 7 days') and discharge destination ('non-routine' vs. 'routine'), controlling for patient and hospital characteristics. Recipients of SRS alone (ATE = - 0.071, CRR = 0.88, MOR = 0.75) or SRS + non-SRS (ATE = - 0.17, CRR = 0.70, MOR = 0.50) had shorter hospitalizations as compared to recipients of non-SRS alone. Recipients of SRS alone (ATE = - 0.13, CRR = 0.78, MOR = 0.59) or SRS + non-SRS (ATE = - 0.17, CRR = 0.72, MOR = 0.51) had reduced risks of non-routine discharge as compared to recipients of non-SRS alone. Similar analyses suggested recipients of SRS alone had shorter hospitalizations and similar risk of non-routine discharge when compared to recipients of SRS + non-SRS radiation therapies. SRS alone or in combination with non-SRS therapies may reduce the risks of prolonged hospitalization and non-routine discharge among hospitalized US patients with brain metastases who underwent radiation therapy without neurosurgical intervention.

Epidemiologic Trends in Pleural Infection. A Nationwide Analysis.

Rationale: Recent trends in the care and outcomes of pleural infection are not well characterized.Objectives: To investigate trends in hospital-based healthcare use, outcomes, and management of pleural infection across the United States.Methods: We identified adult hospitalizations for pleural infection from 2005 through 2014 in the Healthcare Cost and Utilization Project-National Inpatient Sample using International Classification of Diseases, Ninth Edition Clinical Modification diagnosis codes. We calculated weighted estimates of national trends in hospitalization, hospital length of stay, hospital mortality, inflation-adjusted cost, and management practices. We tested trend significance using fitted regression models.Results: Over one decade, there was a significant decline in hospitalizations (54.4 per million to 41.2 per million U.S. adult population), length of stay (13.5 ± 0.2 to 11.2 ± 0.2 d), mortality (4.2-2.6%), and costs ($32,829 to $29,458) (all P < 0.001). Both tube thoracostomy and video-assisted thoracoscopic surgery saw an increase as the procedure of first choice, along with declining use of thoracotomy (all P < 0.001). Most patients who underwent video-assisted thoracoscopic surgery (94%) or tube thoracostomy (64.9%) as the initial procedure did not require a second invasive procedure.Conclusions: Over the 21st century's first decade and a half, inpatient costs, use, and mortality have improved among U.S. adults hospitalized with pleural infection. Simultaneously, there has been a shift toward less invasive interventions upfront.
