As the US debates possible policy paths to achieve affordable and sustainable universal health insurance coverage, there has been support for maintaining private choice in the market. Although private insurance is currently central to the US health care system, its potential role, if any, under alternative approaches to coverage expansion, such as Medicare for All, is less clear. Many countries with universal coverage maintain private insurance for services that are not covered. However, Australia is one of the few countries with universal government-sponsored insurance that actively promotes the use of parallel private insurance to supplement public coverage for services that are covered. Currently, about 44% of Australians have some form of private hospital insurance.1 In this article, we discuss the role of private hospital insurance in Australia, some of the benefits and drawbacks, and how the Australian example might inform US policy.

In recent years, amid public outcry over high prices, several large pharmaceutical companies have launched “authorized generic” versions of their brand-name products at steeply reduced list prices, including for epinephrine injectors (EpiPen), insulin (Humalog and NovoLog), and hepatitis C treatments (Harvoni and Epclusa). In each case, the manufacturers garnered positive media attention1,2 when announcing their authorized generic products and the potential savings for patients, even while their brand-name counterparts remained under patent protection for years to come. These examples raise important questions about the incentives for manufacturers of brand-name medicines to introduce authorized generics and whether their availability benefits consumers. In this Viewpoint, we explain what authorized generics are, describe 3 ways that they are used, and consider whether they improve access to prescription drugs or lower out-of-pocket spending for patients.

An extensively revised, retracted, and replaced article by Stefan et al1 in this issue of JAMA Internal Medicine assesses outcomes associated with antibiotic treatment in adults hospitalized for asthma exacerbations. About half of such patients are treated with antibiotics (primarily macrolides and quinolones) without a clear clinical indication. Stefan et al1 found that while treatment with antibiotics on day 1 of hospitalization was associated with slightly increased length of stay and costs, it was associated with a statistically significant 1.1% (95% CI, 0.2% to 1.9%) absolute reduction in the risk of treatment failure (7.1% vs 8.2%), defined as initiation of mechanical ventilation, transfer to the intensive care unit after hospital day 1, in-hospital mortality, or readmission for asthma exacerbation within 30 days of discharge. They conclude that their results “highlight the need to perform randomized clinical trials to determine the role of antibiotic prescribing among patients hospitalized for asthma exacerbation.”1

widespread availability of commercial assays that detect anti–severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) antibodies has enabled researchers to examine naturally acquired immunity to coronavirus disease 2019 (COVID-19) at the population level. Several studies have found that the SARS-CoV-2 seroprevalence (the percentage of the population with serum containing antibodies that recognize the virus) has remained below 20% even in the most adversely affected areas globally, such as Spain and Italy.1-3 In this issue of JAMA Internal Medicine, Bajema et al4 contribute new information on the shifting nature of SARS-CoV-2 seroprevalence in the US. The study uses national data to expand on an earlier US Centers for Disease Control and Prevention study of seroprevalence of antibodies to SARS-CoV-2 in 10 US sites.3

after a hard year, good news related to coronavirus disease 2019 (COVID-19) is welcome. In this issue of JAMA Internal Medicine, Asch and colleagues1 provide a reason for optimism that our health care system has improved in our ability to care for persons with COVID-19. The authors performed a national analysis of COVID-19–associated mortality that spanned 955 US hospitals, representing nearly 40?000 patients. Using administrative claims data from a large national health insurer, they found that a hospital’s risk-standardized event rate (a composite of hospital mortality or referral to hospice) because of COVID-19 had significantly decreased. Specifically, the risk-adjusted mortality decreased from 16.56% to 9.29% in the early period of this study (January through April 2020) compared with the later period (May through June 2020).

For approval of cancer drugs, the US Food and Drug Administration (FDA) is tolerant of uncertainty and prioritizes speed over other factors.1 Most drug approvals are based on surrogate markers, such as tumor shrinkage in a fraction of patients (response rate) or delayed tumor growth (progression-free survival). These surrogates use arbitrary percentage cutoffs and are not optimized to ensure that a drug can improve the length or quality of life.2

The concept of prediabetes (and similar concepts of impaired fasting glucose and impaired glucose tolerance) formally emerged in the 1990s to better characterize the incremental pathophysiology leading to the eventual development of diabetes.1 It is defined by ranges of disordered glucose values between normal and diabetes (eg, hemoglobin A1c levels, 5.7%-6.4% [to convert to the proportion of total hemoglobin, multiply by 0.01]). We treat it as a risk factor for diabetes; in midlife, those with a hemoglobin A1c level of 6.0% to 6.5% have 20 times the risk of developing diabetes compared with those with a hemoglobin A1c level of 5.0%.2

To diminish potential barriers to treatment access, 3 days later, federal guidelines on telemedicine use were released, providing authorized practitioners increased flexibility to prescribe buprenorphine to patients with opioid use disorder (OUD) during this public health emergency.3 Other local, state, and federal policy initiatives have also attempted to preserve access to medication treatment for OUD, yet the cumulative outcome of these undertakings is not clear.

A patient in their 40s with a history of remote coronary artery bypass grafting, heart failure with reduced ejection fraction, and poorly controlled insulin-dependent diabetes was admitted to the cardiac intensive care unit with acute decompensated heart failure. The patient’s baseline electrocardiogram (ECG) demonstrated normal sinus rhythm, with normal PR and QRS intervals at 132 and 82 milliseconds, respectively. With poor response to intravenous (IV) diuretics, the patient underwent right heart cardiac catheterization, which demonstrated a low cardiac index, high left ventricular filling pressure, and elevated systemic vascular resistance. The patient’s outpatient use of metoprolol was discontinued, and IV dobutamine (5.0 µg/kg/min) was initiated with continuing aggressive IV diuresis. While defecating on the bedside commode, the patient became lightheaded and unresponsive. The patient’s pulse was barely palpable, and the ECG rhythm showed bradycardia (Figure).

To the Editor The Physician Perspective by Reuben1 on sideline guilt should strike a deep chord for many of us. I am a family physician, 72 years old, 6 years retired after an episode of ill health from which I have recovered. So I have my health, food in the refrigerator, enough money in the bank, and a spouse who still puts up with me. The only hardship we face is that coronavirus disease 2019 (COVID-19) has kept us from seeing our far-flung children and grandchildren and forced us to socialize distantly with our friends. Many of my pre-pandemic activities—working as a nursing home ombudsman, teaching medical students, serving on hospital committees—have been curtailed completely or relegated to virtual visits. That I, as a noncritical care specialist, could meaningfully replace a frontline worker is a dubious proposition at best. As Reuben1 points out, staying away from hospitals may be the most constructive thing some of us can do. But beyond the world of medicine, there is so much more to feel guilty about. The COVID-19 pandemic and current events have brought into sharp focus the long-standing racial and class inequities from which I and so many who might read this have undoubtedly benefited in one way or another. I would add 2 suggestions to those Reuben1 has proposed. First, allow yourself to experience gratitude if you float in the same guilty boat as I do: gratitude that you have the boat. Second, get angry about the state of the world and get motivated. The Viewpoint by Berwick2 on the moral determinants of health is a good place to start. There is much that those of us who are blessed not to be suffering in these difficult times can do to help make sure the new normal will better than the old.

To the Editor As the coronavirus disease 2019 (COVID-19) pandemic charges ahead, I too have felt the sideline guilt that David Reuben1 described in his recent Physician Perspective. I retired from active patient care several years ago. Truth be told, it has been decades since I had acute-care skills that might be useful in today’s intensive care units. Nevertheless, as a retiree, I am tormented by the undeniable horrors of the pandemic.

In Reply I would like to thank Kahn and Bruce as well as other retired physicians who contacted me directly for their reflections on sideline guilt.1 While acknowledging the guilt emotion described in the article, they seem less disturbed about not being on the front lines of the battle. Perhaps that is because this is no longer a possibility, as they stepped down from direct patient care roles before the pandemic. Yet these physicians remain engaged and remarkably energetic, channeling this energy into advocacy for health care financing reform (Kahn) and for a broader set of societal issues (Bruce). I am also struck by the expressions of how thankful they are for personally being spared infection by the virus. For them, gratitude rather than guilt is a more prominent emotion.

To the Editor By September 11, 2020, there were more than 28 million people infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) worldwide (https://coronavirus.jhu.edu/). In a recent issue of JAMA Internal Medicine, an Original Investigation by Lee et al1 found that the negative conversion rate in asymptomatic cases was higher than that in symptomatic cases, although to a statistically insignificant degree (Figure 11). However, the negative conversion rate and its comparison between symptomatic and asymptomatic cases may be biased for the following reasons.

In Reply We wish to thank Zhang et al for their comments on our Original Investigation.1 They considered the overestimation of the negative conversion rate owing to the use of a single negative result to define negative conversion. During the study, the Korean Center for Disease Control and Prevention also recommended that quarantined individuals should be released after 2 consecutive negative polymerase chain reaction results from the upper respiratory tract in a 24-hour interval,2 similar to the guidelines from the China National Health Commission.3 We defined the first negative conversion as the first negative result for both upper and lower respiratory tract specimens. In Kaplan-Meier curves of 2 consecutive negative conversion proportions of specimens from the upper and lower respiratory tract, we confirmed that negative conversion rates are not statistically different between symptomatic and asymptomatic patients in either upper respiratory or lower respiratory specimens.1

To the Editor In a recent issue of JAMA Internal Medicine, Sacks and colleagues1 examined the variation in state regulations regarding how pharmacists can substitute prescriptions for brand-name drugs with generic drugs and biosimilars. The authors found substantial variation in state regulations, suggesting a need to optimize state drug product selection laws to promote bioequivalent generic drug and biosimilar substitution.

In Reply In their response to our Original Investigation,1 Cho and Jun raise interesting points about the reach and limitations of state drug product selection laws. While many biologic medications bypass pharmacist dispensing and are administered by physicians in an outpatient setting, many that account for substantial spending do not. The 2 examples that Cho and Jun mention, adalimumab and etanercept, accounted for approximately $3.2 billion and $1.9 billion in reported Medicare Part D spending, respectively, in 2018.2 Several other top-selling biologics, such as the interleukin (IL)-12/IL-23 antagonist ustekinumab, the IL-17 inhibitor secukinumab, and insulin products—which were reclassified as biologics in March 20203 and alone account for many billions of dollars in annual expenditures in the US—are also primarily pharmacy dispensed. Therefore, meaningful health system savings can result from optimizing state drug product selection laws to facilitate interchangeable biosimilar use.

To the Editor In their Original Investigation published in the March 2019 issue of JAMA Internal Medicine, Stefan et al1 reported a 1-day higher median length of stay among patients admitted for acute asthma who were treated with antibiotics for at least 2 days starting in the first 2 days of their hospitalization, compared with propensity score–matched controls not so treated. The authors should clarify how the timing of antibiotic exposure and length of stay were determined because it seems like the study might be susceptible to immortal time bias,2 in which there is a period in the exposed group during which they are not at risk of the outcome (which in this case is discharge from the hospital).

In Reply On behalf of our coauthors, we thank Dr Newman1 for raising concern that our study reported in the article, “Association of Antibiotic Treatment With Outcomes in Patients Hospitalized for an Asthma Exacerbation Treated With Systemic Corticosteroids,” published in the March 2019 issue of JAMA Internal Medicine,2 was susceptible to immortal time bias because of how we had determined the timing of antibiotic exposure and length of stay in our original analysis.

in the article by Rooney et al titled “Risk of Progression to Diabetes Among Older Adults With Prediabetes,” published online February 8, 2021, and also in the April 2021 print issue of JAMA Internal Medicine,1 because of a calculation error, the incidence rates in Results, Table 2, and eTable 3 in the Supplement were incorrectly reported and have been replaced with corrected values. In addition, text was omitted from the first sentence in the findings portion of the Key Points. The corrected sentence now reads, “In this cohort study of 3412 older adults, the prevalence of prediabetes (mean [SD] age, 75.6 [5.2] years) was high and differed substantially depending on the definition used, with estimates ranging from 29% for glycated hemoglobin levels of 5.7% to 6.4% and fasting glucose levels of 100 to 125 mg/dL to 73% for either glycated hemoglobin levels of 5.7% to 6.4% or fasting glucose levels of 100 to 125 mg/dL.” The overall interpretation and implications of the study still stand.
