Introduction: The intensive care unit (ICU) consumes 20% of hospital expenditures and 1% of gross domestic product. Many strategies have been attempted to reduce ICU costs. A systematic review was conducted to evaluate the effect of palliative care (PC) consultations in the ICU on length of stay (LOS) and costs. Methods: A literature search was...

Background Despite the high cost associated with ICU use at the end of life, very little is known at a population level about the characteristics of users and their end of life experience. In this study, our goal was to characterize decedents who received intensive care near the end of life and examine their overall health care use prior to death....

Background In end-of-life situations, the phrase “do everything” is sometimes invoked by physicians, patients, or substitute decision-makers (SDM), though its meaning is ambiguous. We examined instances of the phrase “do everything” in the archive of the Ontario Consent and Capacity Board (CCB) in Canada, a tribunal with judicial authority to adjud...
Article
Background: Adverse events (AEs) are defined as unintended complications occurring to patients as a result of medical care. AEs are especially prevalent in the intensive care unit (ICU) setting and may lead to negative patient outcomes. Although many studies have examined the impact of AEs on patient outcomes, few have investigated their associated...
Article
Introduction: Frailty is a robust predictor of adverse outcomes in older people. Practice guidelines recommend routine screening for frailty; however, this does not occur regularly. The Clinical Frailty Scale (CFS) is a validated, feasible instrument that can be used in a variety of clinical settings and is associated with many adverse outcomes. O...
