The use of marijuana is associated with a marked increase in the risk of being involved in severe trauma particularly motor vehicle collisions. In 2009, for instance, marijuana use was a contributing factor in more than 460,000 emergency department visits in the United States.
But we also know that cannabis is potentially neuroprotective. Previous studies have found that tetrahydrocannabinol (THC), the active ingredient in marijuana, may have beneficial effects in certain types of neurodegenerative processes, like Alzheimer’s and Huntington’s disease. In addition, previous studies indicate THC may protect the brain in animal models of neurologic injury. However, clinical trials of a synthetic THC derivative were not ultimately associated with an increase in survival in patients with traumatic brain injury. Since overall findings were mixed, we hypothesized that use of the “native” form of THC could be associated with an increase in survival in patients with traumatic brain injury.
Thanks to extraordinary advances in medicine, critical care providers can save lives even when the cards are stacked against their patients. However, there are times when no amount of care, however cutting-edge it is, will save a patient. In these instances, when physicians recognize that patients will not be rescued, further critical care is said to be “futile.” In a new study, my RAND and UCLA colleagues and I find that critical care therapies that physicians regard as “futile” are not uncommon in intensive care units, raising some uncomfortable questions.
Of course, we’re fortunate to have such fantastic technology at our disposal — but we must address how to use it appropriately when the patient may not benefit from high-intensity measures. When aggressive critical care is unsuccessful at achieving an acceptable level of health for the patient, treatment should focus on palliative care.
A national shortage of critical care physicians and beds means difficult decisions for healthcare professionals: how to determine which of the sickest patients are most in need of access to the intensive care unit. What if patients’ electronic health records could help a physician determine ICU admission by reliably calculating which patient had the highest risk of death?
Emerging health technologies – including reliable methods to rate the severity of a patient’s condition – may provide powerful tools to efficiently use scarce and costly health resources, says a team of University of Michigan Health System researchers in the New England Journal of Medicine.
“The lack of critical care beds can be frustrating and scary when you have a patient who you think would benefit from critical care, but who can’t be accommodated quickly. Electronic health records – which provide us with rich, reliable clinical data – are untapped tools that may help us efficiently use valuable critical care resources,” says hospitalist and lead author Lena M. Chen, M.D., M.S., assistant professor in internal medicine at the University of Michigan and an investigator at the Center for Clinical Management Research(CCMR), VA Ann Arbor Healthcare System.
The UMHS and VA study referenced in the article finds that patients’ severity of illness is not always strongly associated with their likelihood of being admitted to the ICU, challenging the notion that limited and expensive critical care is reserved for the sickest patients. ICU admissions for non-cardiac patients closely reflected severity of illness (i.e., sicker patients were more likely to go to the ICU), but ICU admissions for cardiac patients did not, the study found. While the reasons for this are unclear, authors note that the ICU’s explicit role is to provide care for the sickest patients, not to respond to temporary staffing issues or unavailable recovery rooms.
