RESUMEN

Physicians may under some circumstances decline to provide a clinical service that is within accepted medical standards due to a deeply held moral belief that to do so would be wrong. Conscience objection in medicine is legally protected, but ethically limited by physician obligations to put patient interests first. Accommodation to conscientious objections, when possible, recognizes the diverse moral perspectives and benefits for both the objectors and the profession as a whole. When these situations arise, physicians have obligations to respectfully resolve the distress of conscientious objectors while still honoring the primacy of patient care needs.

RESUMEN

Some practices require mandatory preoperative laboratory testing for select patients presenting for anesthesia and surgery. Such mandatory preanesthesia laboratory testing has significant ethical implications related to informed consent and patient autonomy. Assumptions that a patient provides "presumed consent" by merely presenting for a test are flawed because such consents are often not informed and do not acknowledge patient autonomy. By placing a condition on access to a medical treatment, mandatory preanesthesia testing may not be ethically justifiable. Not all laboratory tests are "ethically equal"; several raise specific questions regarding informed consent, related to their potential to cause significant harm.

RESUMEN

Respect for patient autonomy is a pillar of medical ethics, manifested predominantly through informed consent. Mandatory (routine) nonconsented preoperative urine pregnancy testing does not adequately respect patient autonomy, is potentially coercive, and has the potential to cause harm medically, psychologically, socially, and financially. Inaccuracies in pregnancy testing can result in false-positive and false-negative results, especially in early pregnancy. There is substantial scientific evidence that anesthesia is not harmful to the fetus, raising the question of whether pregnancy testing provides substantial benefit to the patient. Not performing a preanesthesia pregnancy test has not been associated with significant medicolegal consequences. We review the ethical implications of mandatory preanesthesia pregnancy testing in light of these facts.

RESUMEN

Once medical drugs and devices are approved for marketing by the FDA they can legally be used for purposes and in ways other than the ones for which they have been tested and approved. However, it is illegal for manufacturers to advertise or promote such unapproved uses of the drugs and devices. Part 1 of this review focuses on off-label use of FDA-approved therapies. Part 2 addresses illegal off-label marketing of drugs and devices. While off-label use can be beneficial to patients, unless carefully undertaken off label use may undermine the important safety mission of the FDA, can expose patients to elevated risks without proven benefits (or possibly no benefit), and can reduce motivation of companies to study the safety and risks of off-label use of therapies. These problems are further amplified when off-label use occurs among very vulnerable patient populations such as the elderly, patients with mental health disorders, pregnant women and pediatric patients. This review considers ethical issues in off-label use, as well as important steps for physicians considering an off-label prescription of a drug or device.

RESUMEN

Phase I and II clinical trials increasingly combine therapeutic and toxicity endpoints. Recently, therapeutic agents have even achieved U.S. Food and Drug Agency approval based on early phase trials alone. These developments point to new challenges in assuring the safety of human research subjects and patients. Given their size and use of real-world patients, phase III studies warrant independent monitoring by a Drug Safety Monitoring Board (DSMB). Requirements should also be extended to include many phase I and II clinical trials. Measures should be taken to establish and standardize minimum qualifications for service on a DSMB.

RESUMEN

Two major legislative actions since 2015, the 21st Century Cures Act of 2016 and the U.S. Food and Drug Administration (FDA) Reauthorization Act of 2017, contain significant provisions that potentially streamline drug development times, and by extension, may reduce costs. Evidence suggests, however, that development times have already been significantly affected by previous legislation and FDA programs, through accelerated approval pathways and adoption of more flexible definitions of clinical evidence of efficacy. The COVID-19 pandemic is pushing researchers and commercial entities to further test the limits of drug and vaccine development times and approvals, at an as yet unknown level of risk to patients. COVID-19 drug and vaccine trials are even now making use of accelerated drug approval programs, blended trials, and adaptive trial design to accelerate approval of therapeutics in the pandemic.

RESUMEN

The COVID-19 (coronavirus disease-2019) pandemic has presented unprecedented challenges to regulatory organizations, the biotech and pharmaceutical industry, and the publishing industry. This Translational Perspectives paper attempts to highlight some of the challenges and perils of moving extraordinarily fast in an effort to save human lives in the midst of a global pandemic. As with the development of all new therapeutic approaches, it will take time to assess the risks and benefits of developing new therapies at "warp speed".

RESUMEN

PURPOSE OF REVIEW: Pollution and global warming/climate change contribute to one-quarter of all deaths worldwide. Global healthcare as a whole is the world's fifth largest emitter of greenhouse gases, and anesthetic gases, intravenous agents and supplies contribute significantly to the overall problem. It is the ethical obligation of all anesthesiologists to minimize the harmful impact of anesthesia practice on environmental sustainability. RECENT FINDINGS: Focused programs encouraging judicious selection of the use of anesthetic gas agents has been shown to reduce CO2 equivalent emissions by 64%, with significant cost savings. Good gas flow management reduces nonscavenged anesthetic gas significantly, and has been shown to decrease the consumption of volatile anesthetic agent by about one-fifth. New devices may allow for recapture, reclamation and recycling of waste anesthetic gases. For propofol, a nonbiodegradable, environmentally toxic agent, simply changing the size of vials on formulary has been shown to reduce wasted agent by 90%. SUMMARY: The 5 R's of waste minimization in the operating room (OR) (Reduce, Reuse, Recycle, Rethink and Research) have proven benefit in reducing the environmental impact of the practice of anesthesiology, as well as in reducing costs.

RESUMEN

Dramatically rising costs in drug development are in large part because of the high failure rates in clinical phase trials. The poor correlation of animal studies to human toxicity and efficacy have led many developers to question the value of requiring animal studies in determining which drugs should enter in-human trials. Part 1 of this 2-part series examined some of the data regarding the lack of concordance between animal toxicity studies and human trials, as well as some of the potential reasons behind it. This second part of the series focuses on some alternatives to animal trials (hereafter referred to as animal research) as well as current regulatory discussions and developments regarding such alternatives.

RESUMEN

End-of-life vital organ transplantation involves singular ethical issues, because survival of the donor is impossible, and organ retrieval is ideally as close to the death of the donor as possible to minimize organ ischemic time. Historical efforts to define death have been met with confusion and discord. Fifty years on, the Harvard criteria for brain death continue to be problematic and now face significant legislative efforts to limit their authority.

RESUMEN

Phase II clinical studies represent a critical point in determining drug costs, and phase II is a poor predictor of drug success: >30% of drugs entering phase II studies fail to progress, and >58% of drugs go on to fail in phase III. Adaptive clinical trial design has been proposed as a way to reduce the costs of phase II testing by providing earlier determination of futility and prediction of phase III success, reducing overall phase II and III trial sizes, and shortening overall drug development time. This review examines issues in phase II testing and adaptive trial design.

RESUMEN

Animal testing is used in pharmaceutical and industrial research to predict human toxicity, and yet analysis suggests that animal models are poor predictors of drug safety in humans. The cost of animal research is high-in dollars, delays in drug approval, and in the loss of potentially beneficial drugs for human use. Human subjects have been harmed in the clinical testing of drugs that were deemed safe by animal studies. Increasingly, investigators are questioning the scientific merit of animal research. This review discusses issues in using animals to predict human toxicity in pharmaceutical development. Part 1 focuses on scientific concerns over the validity of animal research. Part 2 will discuss alternatives to animal research and their validation and use in production of human pharmaceuticals.

RESUMEN

U.S. Food and Drug Administration (FDA) approval of Class III medical devices can take from 3 to 7 years. Although this is shorter than times for drug approvals, patients with serious or life-threatening diseases and disorders may not have time to wait for device approval to access needed treatments. The FDA has a number of pathways, similar to drug approval processes, for expanded use of unapproved medical devices in patients for whom no reasonable alternative therapy is available. Additionally, the FDA regulates the manufacture and use of "custom" medical devices-those made for use by 1 specific patient. With the advent of 3-dimensional printing and bioprinting, new rules are evolving to address concerns that lines may be blurred between "custom" treatments and unregulated human experimentation.

RESUMEN

With drug approval times taking an average of 8 years from entry into clinical trials to full U.S. Food and Drug Administration (FDA) approval, patients with life-threatening and severely debilitating disease and no reasonable therapeutic options are advocating for expanded access (EA) to investigational drugs prior to approval. Special investigational new drug (IND) application categories allow patients who meet specific criteria to receive treatment with non-approved drugs. The FDA approves over 99% of all single-patient INDs, providing emergency approval within hours, and non-emergency approval within an average of 4 days. "Right-to-try" laws passed in 38 states would allow patients to bypass FDA processes altogether, but contain controversial provisions that some claim risk more harm than benefit to desperate and vulnerable patients. This review focuses on FDA EA to non-approved drugs through a special category of IND-the single-patient IND-and "right-to-try" (R2T) access outside of the FDA.

RESUMEN

Individual patients with life-threatening or severely debilitating diseases can petition the U.S. Food and Drug Administration (FDA) through their physicians to have expanded access (EA) to drugs that are in clinical trials but have not reached full FDA approval (the "single-patient" investigational new drug [IND] application). Additionally, recent state and federal laws-so-called "right to try legislation"-allow patients to approach drug companies directly for access prior to FDA approval. While these pathways provide potential access for individual patients to investigational drugs, different EA pathways permit entire groups of certain patients to access investigational drugs prior to FDA approval. This review focuses on special categories of EA INDs intended for multiple patients-the intermediate-group IND and the widespread-treatment IND-as well as emergency authorization for use of investigational drugs and biological products (e.g., vaccines) in public health emergencies.

RESUMEN

BACKGROUND: Pulmonary hypertension (PHTN) is associated with increased post-procedure morbidity and mortality. Pre-procedure echocardiography (ECHO) is a widely used tool for evaluation of these patients, but its accuracy in predicting post-procedure outcomes is unproven. Self-reported exercise tolerance has not been evaluated for operative risk stratification of PHTN patients. OBJECTIVE: We analyzed whether self-reported exercise tolerance predicts outcomes (hospital length-of-stay [LOS], mortality and morbidity) in PHTN patients (WHO Class I-V) undergoing anesthesia and surgery. METHODS AND FINDINGS: We reviewed 550 non-cardiac, non-obstetric procedures performed on 370 PHTN patients at a single institution between 2007 and 2013. All patients had cardiac ECHO documented within 1 year prior to the procedure. Pre-procedure comorbidities and ECHO data were collected. Functional status (< or ≥ 4 metabolic equivalents of task [METs]) was assigned based on responses to standard patient interview questions during the pre-anesthesia clinic visit. Multiple logistic regression was used to develop a risk score model (Pulmonary Hypertension Outcome Risk Score; PHORS) and determine its value in predicting post-procedure outcomes. In an adjusted model, functional status <4 METs was independently associated with a LOS >7 days (p < .003), as were higher ASA class (p < .002), open surgical approach (p < .002), procedure duration > 2 hours (p < .001), and the absence of systemic hypertension (p = .012). PHORS Score ≥2 was associated with an increased 30-day major complication rate (28.7% vs. 19.2%; p < 0.001) and ICU admission rate (8.6% s 2.8%; p = .007), but no statistical difference in hospital readmissions rate (17.6% vs. 14.0%; p = .29), or mortality (3.5% vs. 1.4%; p = .75). Similar ECHO findings did not further improve outcome prediction. CONCLUSIONS: Poor functional status is associated with severe PHTN and predicts increased LOS and post-procedure complications in patients with moderate to severe pulmonary hypertension with different etiologies. A risk assessment model predicts increased LOS with fair accuracy. A thorough evaluation of underlying etiologies of PHTN should be undertaken in every patient.

RESUMEN

Eroom's law (Moore's law spelled backwards), describes adverse trends towards declining innovation and rising costs of drug development over the last several decades. Therapeutics for cardiovascular diseases (CVD) appear to have been particularly sensitive to these trends. Thirty-three percent fewer CVD therapeutics were approved between 2000 and 2009 compared to the previous decade, and the number of CVD drugs starting all clinical trial stages declined in both absolute and relative numbers between 1990 and 2012. In the last 5 years, drugs to treat CVD disease comprised just 6% of all new drug launches. This review discusses the decline in CVD therapeutics, the reasons behind it, and ways in which this trend is being or might be addressed.
