Therapeutic futility in intensive care units (ICUs) is still little discussed among nursing professionals responsible for implementing prescribed procedures, which they might disagree on. Therefore, interviews were carried out with ICU nurses to understand how they are coping with the implementation of futile treatments. Based on the analysis of collected data, the following categories emerged:...
BACKGROUND The medical futility rationale asserts that physicians need not offer their patients therapies that have zero or close to zero probability of success. The rationale is controversial, but it is used in practice. OBJECTIVE To examine the attitudes of patients with advanced acquired immunodeficiency syndrome (AIDS) toward the medical futility rationale as it might apply to their medic...
BACKGROUND Publicly funded trials regularly fail to recruit their target sample size or find a significant positive result. Adaptive clinical trials which may partly mediate against the problems are not often applied. In this paper we investigate the potential of a form of adaption in a clinical trial - a futility analysis - to see if it has potential to improve publicly funded trials. METHOD...
OBJECTIVES This study explores physicians' concepts of futility and use of age as a deciding factor in considering medical futility in clinical interventions. DESIGN Survey. SETTING Five academic hospitals in the United States. PARTICIPANTS Participants were 355 internal medicine physicians, including 162 residents, 98 fellows, and 95 attending physicians.

Several definitions for medical futility has been proposed in the literature. Medical futility is defined as the condition in which an intervention, either for diagnosis, prevention, treatment, rehabilitation or other medical goals, has no benefit for the individual patient. This critical review aimed to increase the understanding of physicians and other healthcare providers on the issue of fut...
In this essay I examine the formal structure of the concept of futility, enabling identification of the appropriate roles played by patient, professional, and society. I argue that the concept of futility does not justify unilateral decisions to forego life-sustaining medical treatment over patient or legitimate surrogate objection, even when futility is determined by a process or subject to et...

The emergence of new obstetrical and neonatal technologies, as well as more aggressive clinical management, has significantly improved the survival of extremely low birth weight (ELBW) infants. This development has heightened concerns about the limits of viability. ELBW infants, weighing less than 1,000 grams and no larger than the palm of one’s hand, are often described as “miracles” of late t...
OBJECTIVE To determine if future studies of coenzyme Q(10) and GPI-1485 in Parkinson disease (PD) may be warranted. METHODS We conducted a randomized, double-blind, calibrated futility clinical trial of coenzyme Q10 and GPI-1485 in early untreated PD using placebo data from the DATATOP study to establish the futility threshold. RESULTS The primary outcome measure (change in total Unified Pa...
Early stopping due to futility, also referred to as a go/nogo decision, during interim analysis has become an important feature of clinical trial designs. Current methods for futility stopping in literature are mostly based on conditional power or predictive power in conjunction with the theory of stochastic curtailment or group sequential design. They have certain drawbacks that have been note...
