Illusory generalizability of clinical prediction models.

It is widely hoped that statistical models can improve decision-making related to medical treatments. Because of the cost and scarcity of medical outcomes data, this hope is typically based on investigators observing a model's success in one or two datasets or clinical contexts.

Factors Associated With Inpatient Hospice Utilization Among Hospitalized Decedents With Comfort Measures Only Status.

Patients with serious illness may elect to transition their care to comfort measures only (CMO) while in the hospital. Although studies have shown that routine hospice care is underutilized, the rate of general inpatient hospice (GIP) use among CMO patients during their terminal admission remains unclear. We sought to (1) examine the rate of GIP utilization and (2) identify factors associated with its use among hospitalized CMO decedents.

PTSD and the War of Words.

Trauma-related symptoms among veterans of military engagement have been documented at least since the time of the ancient Greeks. Since the third edition of the Diagnostic and Statistical Manual in 1980, this condition has been known as posttraumatic stress disorder, but the name has changed repeatedly over the past century, including shell shock, war neurosis, and soldier's heart. Using over 14 million articles in the digital archives of the , , and , we quantify historical changes in trauma-related terminology over the past century.
