Examining lack of referrals to heart valve specialists as mechanisms of potential underutilization of aortic valve replacement

BackgroundRecent studies suggest that aortic valve replacement (AVR) remains underutilized. AimsInvestigate the potential role of non-referral to heart valve specialists (HVS) on AVR utilization. MethodsPatients with severe aortic stenosis (AS) between 2015 and 2018, who met class I indication for intervention, were identified. Baseline data and process-related parameters were collected to analyze referral predictors and evaluate outcomes. ResultsAmong 981 patients meeting criteria AVR, 790 patients (80.5%) were assessed by HVS within six months of index TTE. Factors linked to reduced referral included increasing age (OR: 0.95; 95% CI: 0.94-0.97; P < .001), unmarried status (OR: 0.59; 95% CI: 0.43-0.83; P = .002) and inpatient TTE (OR: 0.27; 95% CI: 0.19-0.38; P < .001). Conversely, higher hematocrit (OR: 1.13; 95% CI: 1.09-1.16; P < .001) and eGFR (OR: 1.01; 95% CI: 1.00-1.02; P = .003), mean aortic valve gradient (OR: 1.03; 95% CI: 1.01-1.04; P < .001) and preserved LVEF (OR: 1.59; 95% CI: 1.02-2.48; P = .04), were associated with increased referral likelihood. Moreover, patients assessed by HVS referral as a time-dependent covariate had a significantly lower two-year mortality risk than those who were not (aHR: 0.30; 95% CI: 0.23-0.39; P < .001). ConclusionA substantial proportion of severe AS patients meeting indications for AVR are not evaluated by HVS and experience markedly increased mortality. Further research is warranted to assess the efficacy of care delivery mechanisms, such as e-consults, and telemedicine, to improve access to HVS expertise.

Telehealth and Outcomes in Patients With Cancer: Data and Innovation.

Despite that telehealth has been crucial to the delivery of oncology care during the COVID-19 pandemic, the impact of this care delivery mechanism on outcomes in cancer care has not been rigorously studied relative standard in-person care for patients with cancer. Patient-centered outcomes such as quality of life, patient satisfaction, and symptoms are important outcomes that have been the primary focus of many of the existing studies in this space, yet only a select few have evaluated overall survival and other objective efficacy endpoints. Studies have alluded to positive effects of telehealth on mitigating financial toxicity and enhancing cost-effective care delivery in oncology. Telehealth carries much potential for advancing care for patients with cancer, but future study should focus on additional efficacy endpoints, implementation, and ways to reduce disparities.

Effects of Primary Care-Led, Integrated Palliative Care for Medicare Patients in a Value-Based Model

ContextFaced with a projected shortage of specialized palliative care physicians, scalable palliative solutions are required to better meet the aging population's needs. ObjectivesTo determine whether a multi-site, primary care-led, integrated palliative care model improves clinical, utilization, and economic outcomes. MethodsPropensity score-matched comparison group formed from participants who were Medicare beneficiaries, died January 1, 2021–January 31, 2023, were patients of eight primary care practices that partner with agilon health, and enrolled in palliative care for at least seven days. Each practice operates in a value-based model, where primary care providers (PCPs) take on full-risk for the cost and quality of patient outcomes. Each program includes symptom management, defining goals of care/advance directives, PCP care coordination, and assistance with care transitions if patients enroll in hospice. ResultsFinal sample included 1778 decedents, with 889 in both enrolled and matched cohorts, average age 83. Palliative care is associated with improved patient outcomes from palliative care enrollment until death, including 5.4 more days at home (p < 0.001), 0.4 fewer hospitalizations (p < 0.001), 17% fewer deaths in a hospital (p < 0.001), and $10,393 lower overall healthcare costs (p < 0.001). ConclusionA primary care-led, integrated approach of delivering palliative care within a full-risk model can be an effective care delivery mechanism to meet the healthcare needs of an aging population by impacting patient outcomes and reducing avoidable utilization and cost at the end of life. These findings demonstrate that PCPs in a scaled, full-risk model can simultaneously improve care for patients while reducing costs to the healthcare system.

Accessing Care During the COVID-19 Pandemic Using Telemedicine: Perspectives From People With HIV.

The COVID-19 pandemic has resulted in a steep increase in telemedicine implementation and use. Data are lacking on telemedicine use in marginalized and underserved groups including people with HIV (PWH). The Ryan White HIV/AIDS Program (RWHAP) is the largest single provider of HIV care in the United States (U.S.) and the southern part of the country remains the epicenter of the HIV epidemic. This study recruited PWH from RWHAP clinics across South Texas. To ascertain their perspectives on utilizing telemedicine for HIV care during the COVID-19 pandemic, a survey instrument derived from validated instruments was used. Descriptive statistics were used for client characteristics, quality of telemedicine care, and COVID-19 impact. Wilcoxon Rank Sum and Kruskal-Wallis tests were assessed associations of telemedicine care quality and COVID-19 impact between client groups. Among 246 eligible PWH, 122 clients completed the survey with a response rate of 50%. Clients were predominantly Hispanic males. Significant differences in perception of telemedicine care and the impact of COVID-19 by gender, age, language, and race/ethnicity were observed. Older PWHIV used telemedicine more than younger clients (p = .01). English speakers indicated more impact of the COVID-19 pandemic on daily life than Spanish speakers (p = .02). Worry about the pandemic was most evident among non-Hispanic Black and Hispanic PWH (p = .03). Overall, telemedicine was found to be a favorable and acceptable mechanism of HIV care delivery by PWH in a Southern state during the COVID-19 pandemic.

Seeing Red: Associations between Historical Redlining and Present-Day Visual Impairment and Blindness

Redlining was a discriminatory housing policy in the United States that began in 1933 and denoted neighborhoods with high proportions of Black individuals as "undesirable" and a high risk for lending, which therefore excluded people from obtaining traditional insured mortgages to purchase a home. Simultaneously, realtors discouraged Black individuals from purchasing homes in predominantly non-Black neighborhoods. This resulted in decreased home ownership and wealth accumulation among Black individuals and neighborhoods with high proportions of Black individuals. This study investigated rates of visual impairment and blindness (VIB) in neighborhoods that at one time were graded for redlining. Secondary data analysis of American Community Survey data and historical grades for redlining. United States census tracts (CTs) from 2010 with historical grades for redlining. One-way analysis of variance, Kruskal-Wallis test, chi-square test, and logistic regression modeling. The main outcome was CT percentage of residents reporting VIB and the association with historical grades for redlining. Grades were converted to numeric values (1 to 4, with higher values indicating worse grade) and aggregated over a CT based on the distribution of grades within to obtain a redlining score. Logistic regression was used to model the effect of redlining on the probability of having VIB. Eleven thousand six hundred sixty-eight CTs were analyzed. Logistic regression found that a 1-unit increase in average redlining score was associated with a 13.4% increased odds of VIB after controlling for CT measures of age, sex, people of color (any non-White race), state, and population size (odds ratio [OR], 1.134; 95% confidence interval [CI], 1.131-1.138; P < 0.001). Similar results were observed for an additional model that adjusted for the estimated percentage of Black residents within a CT (OR, 1.180; 95% CI, 1.177-1.183; P < 0.001). Historical government-sanctioned residential segregation through redlining was found to be associated with higher proportions of people living with VIB in these neighborhoods today. Understanding how neighborhood segregation impacts eye health is important for planning improved mechanisms of eye care delivery to mitigate health disparities.

Translational gaps and opportunities for medical wearables in digital health.

A confluence of advances in biosensor technologies, enhancements in health care delivery mechanisms, and improvements in machine learning, together with an increased awareness of remote patient monitoring, has accelerated the impact of digital health across nearly every medical discipline. Medical grade wearables-noninvasive, on-body sensors operating with clinical accuracy-will play an increasingly central role in medicine by providing continuous, cost-effective measurement and interpretation of physiological data relevant to patient status and disease trajectory, both inside and outside of established health care settings. Here, we review current digital health technologies and highlight critical gaps to clinical translation and adoption.

Drive-Through Medicine: A Novel Health Care Delivery Mechanism for the COVID-19 Pandemic

BackgroundCoronavirus disease 2019 (COVID-19) placed additional strain on an already struggling health care system. In response, novel solutions such as telehealth have been explored, however, there is significant room for innovation in health care delivery. ObjectivesThe aim of our study was to evaluate the effectiveness of a drive-through medical treatment system for evaluating patients with COVID-like symptoms. MethodsWe designed a prototype drive-through medical treatment facility (DMF) to triage large volumes of patients quickly and efficiently, while fully evaluating, treating, and discharging low-risk patients. A retrospective chart review was performed to extract clinical and logistical metrics. ResultsA total of 2164 patients were evaluated between May 1 and July 1, 2020. Overall accuracy for patient classification was 92.4% (95% confidence interval [CI] 91.2–93.5%). Screening criteria resulted in a return with need for workup or admission rate of 0.25%, yielding a sensitivity of 83.3% (95% CI 65.3–94.4%). Of those presenting to the DMF, 179 patients (8.3%) were diverted to the main emergency department (ED) for further evaluation, of which 14% received diagnostic workups and 5% subsequent admission to an inpatient service, yielding a specificity of 92.8% (95% CI 91.7– 93.9%). Length of stays for those seen in the DMF vs. the main ED (M = 38 min vs 149 min) yielded a mean difference of 111 min per encounter and a total time savings of 3762 h. ConclusionDrive-through medical systems can accurately triage patients presenting with potential COVID-19 and effectively treat lower-risk patients, thereby reducing ED utilization.

Evolution of the US health care system has been punctuated by periods of rapid change. In the coming decades there will be meaningful and potentially disruptive developments in health care delivery mechanisms, the policy environment, and the populations for whom we provide care. Neurologists will need to adapt to changing patient expectations, market dynamics, and regulatory structures to thrive in the future health care environment. This article describes a forecast of potential changes in the US health care system by 2035, an assessment of the implications for the field of neurology, and a rationale for long-term strategic planning to prepare.

The rate of use of Veterans Affairs chiropractic care: a 5-year analysis

BackgroundThe US Department of Veterans Affairs (VA) has initiated various approaches to provide chiropractic care to Veterans. Prior work has shown substantial increase in use of VA chiropractic care between fiscal years (FY) 2005–2016. However, the extent of the availability of these services to the Veteran population remains unclear. The purpose of this study was to analyze the rate of Veteran use of VA chiropractic services, both from on-site care at VA facilities and VA purchased care from community care providers. This study analyzed facility characteristics associated with chiropractic use by both care delivery mechanisms (on-site and in the community).MethodsCross-sectional analyses of administrative data were conducted for FY 2014–2019. Data were obtained from VA’s Corporate Data Warehouse. The variables extracted included number of unique Veterans receiving VA chiropractic care on-site and in the community, total Veteran population of the VA facilities, size of the VA chiropractic workforce (measured as Full-Time Equivalent, FTE), and facility characteristics (geographic region and the facility complexity). Descriptive statistics, mixed model, and multivariant models were used to analyze data.ResultsUse of VA chiropractic care increased over the six-year period for both on-site and community care. National average for on-site use of the population was 1.27% in FY14 and 1.48% in FY19. Community care use was 0.29% and 1.76% for the same years. Use at individual facilities varied widely in each FY. Factors such as chiropractor FTE, geographic locations, and the complexity of the VA facility are associated with use of chiropractic services.ConclusionThe VA has expanded the non-pharmacologic treatments available to Veterans by providing chiropractic services, yet chiropractic use remains low compared to other US populations. As Veterans have a high prevalence of pain and musculoskeletal conditions, continued work to assess and achieve the optimal levels of chiropractic use in this population is warranted.

Substance use disorders during the COVID-19 pandemic: looking for new innovative approaches.

Background and aim:The destructive impact of the still ongoing COVID-19 pandemic on those struggling with substance use disorders (SUD) stems from the daunting challenges which SUD patients experience in terms of coping with their condition and receiving care in a timely fashion.Methods:Patients struggling with addiction are at particularly high risk, due to the underlying vulnerabilities in their conditions and the stigmatization they often suffer. New Psychoactive Substances stand out as a critical area of concern. The authors have conducted a broad-ranging search to assess the impact of SUDs, along with their related mental, physical, and behavioral symptoms, against the backdrop of the COVID-19, taking into account how drug trafficking and consumption trends have evolved as the emergency draws out, and the cyberspace comes to play an ever-bigger role.Results:Given that roughly 1.5%-5% of the global burden of disease can be ascribed to alcohol abuse and substance addiction, the role of pandemic-related potential contributing factors in the exacerbation and relapse of SUDs and behavioral addiction cannot be discounted and needs targeted measures tailored to the special needs of SUD patients. Escalating environmental stressors stemming from abnormal circumstances can undermine recovery efforts and threaten the very survival of countless SUD patients, increasing the likelihood of relapsing for those in recovery.Conclusions:Policymakers and legislators have not yet put in place targeted measures and adjustments in the health care delivery mechanisms in order to countervail the pandemic impact on SUD sufferers, and the ever-evolving patterns of use and trafficking.

Identifying Barriers to and Opportunities for Telehealth Implementation Amidst the COVID-19 Pandemic by Using a Human Factors Approach: A Leap Into the Future of Health Care Delivery?

The extensive uptake of telehealth has considerably transformed health care delivery since the beginning of the COVID-19 pandemic and has imposed tremendous challenges to its large-scale implementation and adaptation. Given the shift in paradigm from telehealth as an alternative mechanism of care delivery to telehealth as an integral part of the health system, it is imperative to take a systematic approach to identifying barriers to, opportunities for, and the overall impact of telehealth implementation amidst the current pandemic. In this work, we apply a human factors framework, the Systems Engineering Initiative for Patient Safety model, to guide our holistic analysis and discussion of telehealth implementation, encompassing the health care work system, care processes, and outcomes.

Novel Coronavirus (COVID-19): telemedicine and remote care delivery in a time of medical crisis, implementation, and challenges.

The novel Coronavirus (COVID-19) caused by the SARS-CoV-2 virus has led to many challenges throughout the world, one of which is the delivery of health care to patients while they remain home. Telemedicine, or the use of electronic information and telecommunication technologies to support and promote long-distance clinical health care, has been utilized by health care providers for many years, but its widespread implementation did not occur until the onset of the COVID-19 pandemic. Currently, it has become the primary mechanism of care delivery for patients during the COVID-19 pandemic. While obstacles are present for hospitals and providers to establish these services, most barriers exist with patient access. Patients require advanced technical support, translator services, and other measures to become comfortable engaging in a telemedicine encounter. In addition, appropriate follow-up must be provided for chronic medical illnesses and malignancies, helping to prevent the evolution of these conditions during the COVID-19 crisis. Finally, we must ensure equity for all patients seeking to access health services, including those of lower socioeconomic status. Many of these patients rely on public hotspots or library computers for their internet connectivity, but this is likely not conducive to a clinical encounter. These barriers must be addressed to ensure health equity for all patients seeking care. Telemedicine can connect patients and providers during this time of crisis and hopefully will serve as a model for continued use after the pandemic has abated.

Cardiac Rehabilitation During the COVID-19 Era: Guidance on Implementing Virtual Care

Cardiac rehabilitation programs across Canada have suspended in-person services as a result of large-scale physical distancing recommendations designed to flatten the COVID-19 pandemic curve. Virtual cardiac rehabilitation (VCR) offers an alternate mechanism of care delivery, capable of providing similar patient outcomes and safety profiles compared with centre-based programs. To minimize care gaps, all centres should consider developing and implementing a VCR program. The process of this rapid implementation, however, can be daunting. Centres should initially focus on the collation, utilization, and repurposing of existing resources, equipment, and technology. Once established, programs should then focus on ensuring that quality indicators are met and care processes are protocolized. This should be followed by the development of sustainable VCR solutions to account for care gaps that existed before COVID-19, and to improve cardiac rehabilitation delivery, moving forward. This article reviews the potential challenges and obstacles of this process and aims to provide pragmatic guidance to aid clinicians and administrators during this challenging time.

Pediatrician Attitudes Toward and Experiences With Telehealth Use: Results From a National Survey.

BackgroundThe American Academy of Pediatrics 2015 policy statement on telehealth proposed that telehealth could increase access to high-quality pediatric care and that pediatricians should work to reduce barriers to telehealth for their patients. However, little is known about pediatricians’ experiences with and attitudes toward telehealth.MethodsData from a nationally representative survey of American Academy of Pediatrics postresidency US member pediatricians in 2016, restricted to respondents providing direct patient care (n = 744; response rate = 48.7%). Survey collected information on experience with telehealth in the previous 12 months, perceived barriers to telehealth incorporation, and conditions under which nonusers would consider using telehealth. In addition to descriptive statistics, we used multivariable logistic regression to examine characteristics associated with any telehealth experience in the past 12 months.ResultsFifteen percent of pediatricians reported any telehealth use in the 12 months prior to the survey. The most commonly reported barriers to telehealth adoption were insufficient payment and billing issues. Multivariable regression models indicated that pediatricians in rural areas, the West, and subspecialists were most likely to report telehealth use, and identifying barriers was negatively associated with telehealth use. Among nonusers, over half indicated they would consider adopting telehealth if they were paid for the visits.ConclusionTelehealth is considered an important health care delivery mechanism, but only 15% of pediatricians in 2016 reported having used telehealth. Reducing barriers will be instrumental in promoting future telehealth adoption. Many barriers have been reduced during the response to COVID-19, and the impact of these policy changes will need further study.

IMPACT OF A CARDIOLOGY FELLOWSHIP NIGHT FLOAT SYSTEM ON LENGTH OF STAY AND DOOR TO BALLOON TIME

With the escalating complexity of patients with cardiovascular disease, there is increased incentive to improve mechanisms of care delivery. Systems-based practices and educational models can be leveraged to meet this goal. Herein we describe the implementation of a cardiology fellowship night float

Palliative care and Parkinson's disease: outpatient needs and models of care over the disease trajectory.

A palliative approach to care is person-centered and aims to minimize overall disease burden among patients with serious illnesses. There is rising interest in the role of palliative care to improve quality of life among patients with Parkinson's disease (PD). While there is a clear indication for palliative care involvement in those with advanced disease, there is also increasing evidence for the role palliative care may play earlier in the course of PD. However, optimal methods for timing and implementation of these services remain unclear. Here, we aim to explore the palliative needs of individuals with PD from the time of diagnosis over the entire course of the illness. We discuss methods for delivering palliative care services including consultative specialty palliative care, neurologist or primary care-delivered palliative care (primary palliative care), and the emerging specialty of neuropalliative care. We also explore novel care delivery methods and their role in improving patient access to palliative services. We argue that primary palliative care is optimally positioned for the delivery of palliative care for the majority of patients with PD over the course of their illness and explore how and when palliative medicine or neuropalliative specialists can supplement this care. Finally, we describe gaps in our current understanding of outpatient palliative care delivery among the PD population including the development of better methods to identify the palliative needs of patients, the validation of novel care delivery mechanisms, and the need to enhance neurologists' and other medical providers' education in the provision of palliative care services.

Maternal health status in tribal India: A 5-year intervention program and its outcome

Introduction:There is poor penetration of evidence-based maternal health care provided under national health programs in resource-poor underserved regions. A well-planned locally acceptable community-driven comprehensive health promotion strategy and quality health care delivery mechanism is necessary to improve the situation.Objective:The main objective was to find the gaps in the existing system and promote health literacy and health-seeking behavior.Methodology:80,000 tribal population living in isolated conflict zone of Bastar district was covered for 5 years between 2012 and 2017. An integrated health-care plan was developed with community leaders, panchayat, and the local government to promote and provide quality evidence-based maternal health care. Available resources were mobilized and health technologies introduced.Results:Regular home visits, point of care diagnostics, identification of high-risk mothers and their timely referral, and behavioral change communication increased the trust of the community. It resulted in higher demand for evidence-based health interventions. The adolescent pregnancy rate (<19 years) reduced to 6.8% (2016) from 13.5% (2012). Hemoglobin level >9 g% (third trimester) improved. Supervised births and high-risk referrals increased from 19.5% (2014) to 58% (2017) and 8.5% (2014) to 13.1% (2017), respectively. Although significant improvement was noted, key indicators continued to remain below rural Bastar (National Family Health Survey-4).Conclusion:Promotion of existing good practices, behavior change, health technologies, and evidence-based emergency care improved the maternal health status of the secluded and underserved tribal community, but persistent effort is needed to enable women access the quality maternal health services provided under National Health Mission.

Incorporation of Telestroke into Neurology Residency Training: "Time Is Brain and Education".

Background: With increasing demand for neurologists, nontraditional health care delivery mechanisms have been developed to leverage this limited resource. Introduction: Telemedicine has emerged as an effective digital solution. Over the past three decades, telemedicine use has steadily grown; however, neurologists often learn on the job, rather than as part of their medical training. The current literature regarding telestroke training during neurology training is sparse, focusing on cerebrovascular fellowship curricula. We sought to enhance telestroke training in our neurology residency by incorporating real-life application. Materials and Methods: We implemented a formal educational model for neurology residents to use telemedicine for remote acquisition of the National Institutes of Health Stroke Scale (NIHSS) for patients with suspected acute ischemic stroke (AIS) before arrival at our comprehensive stroke center. This three-phase educational model involved multidisciplinary classroom didactics, simulation exercises, and real-world experience. Training and feedback were provided by neurologists experienced in telemedicine. Results: All residents completed formal training in telemedicine prehospital NIHSS acquisition and had the opportunity to participate in additional simulation exercises. Currently, residents are gaining additional experience by performing prehospital NIHSS acquisition for patients in whom AIS is suspected. Our preliminary data indicate that resident video encounters average 10.6 min in duration, thus saving time once patients arrive at our hospital. Discussion: To our knowledge, this is the first report of a telestroke-integrated neurology residency program in a comprehensive stroke center resulting in shortened time to treatment in patients with suspected AIS. Conclusions: We present a model that can be adopted by other neurology residency programs as it provides real-world telemedicine training critical to future neurologists.

Investigating acceptance of telemedicine services through an extended technology acceptance model (TAM)

BackgroundDeveloping countries around the globe are striving continuously to provide free access to health care services. Telemedicine services represent a significantly increasing form of an adequate health care delivery mechanism in developing countries. Research objectiveThis research study was aimed at investigating the factors influencing the acceptance of telemedicine services among the rural population of Pakistan. Technology Acceptance Model (TAM) was used as a theoretical framework for this research, with the inclusion of several other antecedents. Research methodA face-to-face survey method was used to collect research data from 275 participants. The data were analyzed using Partial Least Squares (PLS) method. ResultsThe findings suggest that usage intention of telemedicine services is a function of perceived ease of use, technological anxiety, social influence, perceived ease of usefulness, trust, facilitating conditions, perceived risk, and resistance to technology. ConclusionsThis research study confirms the applicability of TAM with the inclusion of additional variables to model the adoption of telemedicine services in developing countries. The study offers valuable information for policymakers and health service providers for understanding the facilitators and inhibitors influencing the large scale implementation of telemedicine services. The research findings regarding factors including perceived risk, trust, facilitating conditions and resistance to change can aid in the design and adequate provision of telemedicine services in developing countries.
