Pandemic Perspective: Commonalities Between COVID-19 and Cardio-Oncology.

Overlapping commonalities between coronavirus disease of 2019 (COVID-19) and cardio-oncology regarding cardiovascular toxicities (CVT), pathophysiology, and pharmacology are special topics emerging during the pandemic. In this perspective, we consider an array of CVT common to both COVID-19 and cardio-oncology, including cardiomyopathy, ischemia, conduction abnormalities, myopericarditis, and right ventricular (RV) failure. We also emphasize the higher risk of severe COVID-19 illness in patients with cardiovascular disease (CVD) or its risk factors or cancer. We explore commonalities in the underlying pathophysiology observed in COVID-19 and cardio-oncology, including inflammation, cytokine release, the renin-angiotensin-aldosterone-system, coagulopathy, microthrombosis, and endothelial dysfunction. In addition, we examine common pharmacologic management strategies that have been elucidated for CVT from COVID-19 and various cancer therapies. The use of corticosteroids, as well as antibodies and inhibitors of various molecules mediating inflammation and cytokine release syndrome, are discussed. The impact of angiotensin converting enzyme inhibitors (ACEIs) and angiotensin receptor blockers (ARBs) is also addressed, since these drugs are used in cardio-oncology and have received considerable attention during the COVID-19 pandemic, since the culprit virus enters human cells via the angiotensin converting enzyme 2 (ACE2) receptor. There are therefore several areas of overlap, similarity, and interaction in the toxicity, pathophysiology, and pharmacology profiles in COVID-19 and cardio-oncology syndromes. Learning more about either will likely provide some level of insight into both. We discuss each of these topics in this viewpoint, as well as what we foresee as evolving future directions to consider in cardio-oncology during the pandemic and beyond. Finally, we highlight commonalities in health disparities in COVID-19 and cardio-oncology and encourage continued development and implementation of innovative solutions to improve equity in health and healing.

Implementation and Assessment of an Ambulatory Prescribing Guidance Tool to Improve Patient Safety in the Geriatric Population.

OBJECTIVE: The purpose of this study was to assess the effects of a clinical decision support (CDS) tool aimed at decreasing the prescribing of glyburide, a potentially inappropriate medication (PIM), in patients 65 years of age and older. DESIGN: Quasi-experimental, pre-post intervention study. SETTING: Ambulatory care clinics of an academic medical center. INTERVENTION: The tool appeared to providers when entering new prescriptions or refills for glyburide. Glimepiride, which is a more appropriate sulfonylurea, was suggested as an alternative at order entry. MAIN OUTCOME MEASURE(S): The primary outcome was the prescribing of glyburide orders, measured as a percentage of the total oral diabetic medications ordered in patients 65 years of age and older, during the study period. The secondary outcome measured was the response to the CDS tool (accept versus reject). RESULTS: The CDS tool alerted providers 101 times during the 90-day postimplementation period. When the tool appeared, patients were transitioned off of glyburide 17.8% of the time. Subanalysis found that when physicians viewed the alert, patients were transitioned off of glyburide 46.2% of the time. As a percentage of the total number of oral diabetic medications, glyburide prescribing was significantly decreased from pre- to postimplementation study period (3.3% vs. 1.2%; P < 0.001). CONCLUSIONS: A CDS tool can be used in the ambulatory care setting to influence prescribing and provide a safer alternative medication. Additional information is needed to test the use of a CDS tool in conjunction with education to ensure providers are comfortable with and understand implications of a CDS tool.

Reduction in Jail Emergency Department Visits and Closure After Implementation of On-Site Urgent Care.

This descriptive study evaluates the impact of implementation of full service on-site urgent care services at the Los Angeles County Jail (LACJ) by examining the number of patients seen at the referral hospital, Los Angeles County + University of Southern California Medical Center (LAC+USC), and the number of hours that the referral hospital was closed to transfers in the periods before and after the development of the LACJ Urgent Care. The appropriate utilization of public resources is a critical priority for an overburdened county medical health care system. Implementing on-site urgent care staffed by emergency physicians led to reductions in the average number of patients transferred to LAC+USC, the average number of monthly closure hours, and the average days per month when closure to transfer occurred, and a cost savings of some $2 million, primarily in personnel costs.

Fostering a Commitment to Quality: Best Practices in Safety-net Hospitals.

In 2007, the Martin Luther King, Jr.-Harbor Hospital (MLK-Harbor), which served a large safety-net population in South Los Angeles, closed due to quality challenges. Shortly thereafter, an agreement was made to establish a new hospital, Martin Luther King, Jr. Community Hospital (MLKCH), to serve the unmet needs of the community. To assist the newly appointed MLKCH Board of Directors in building a culture of quality, we conducted a series of interviews with five high-performing hospital systems. In this report, we describe our findings. The hospitals we interviewed achieved a culture of quality by: 1) developing guiding principles that foster quality; 2) hiring and retaining personnel who are stewards of quality; 3) promoting efficient resource utilization; 4) developing a well-organized quality improvement infrastructure; and 5) cultivating integrated, patient-centric care. The institutions highlighted in this report provide important lessons for MLKCH and other safety-net institutions.
