The cost of a fall among older adults requiring emergency services.
Researchers evaluated medical expenditures to 1 year among community-dwelling older adults who fell and required ambulance transport, including acute versus post-acute periods, the primary drivers of cost, and comparison to baseline expenditures. They found that older adults who fall and require emergency services have increased healthcare expenditures compared with baseline, particularly during the post-acute period. Comorbidities, noninjury medical conditions, fracture type, and surgical interventions were independently associated with increased costs.

Injured older adults transported by emergency medical services: one year outcomes by POLST status.
Advance care planning documents, including Physician Orders for Life-Sustaining Treatment (POLST), are intended to guide care near end of life, particularly in emergency situations. Yet, research on POLST during emergency care is sparse. This study examined one year outcomes, by Physician Orders for Life-Sustaining Treatment status, of injured adults transported by EMS. The investigators concluded that among injured older adults transported by ambulance in Oregon, one in 5 had an active POLST form at the time of 9-1-1 contact, the prevalence of which increased over the following year.

Long-term outcomes among injured older adults transported by emergency medical services.
This study examined the outcomes of injured older adults who were transported by emergency medical services (EMS) to the hospital. Older adults 65 years and older who were transported by 44 EMS agencies to 51 hospitals in 2011 were included and then had a 12-month follow-up through December 31, 2012. The majority of older adults were transported after a fall (84.5%). Serious injuries occurred in 3.5% with a serious extremity injury being the most common (17.8%). Mortality rates for older adults with severe injuries ranged from 1.6% in the hospital to 20.3% at 1 year. The most common causes of death was cardiovascular diseases and dementia.

Can an out-of-hospital medication history save lives for injured older adults?
In this issue of Annals, Nishijima et al present a much-needed study evaluating the use of anticoagulation and antiplatelet medications as an additional triage criterion to aid in the identification of older adults with intracranial hemorrhage. The authors believe that the new study helps fill a critical void in suggesting that a targeted medication history, formally integrated as a field triage criterion, may be useful in identifying high-risk older adults.

Identification of emergency department visits in Medicare administrative claims: approaches and implications.
The researchers sought to construct an operational definition for ED visitation using a comprehensive Medicare data set and to compare this definition to existing operational definitions used by researchers and policymakers. They concluded that current operational definitions of ED visitation using administrative claims produce different estimates of ED visitation based on the underlying assumptions applied to billing data and data set availability.

Age-related disparities in trauma center access for severe head injuries following the release of the updated field triage guidelines.
Reflecting perceived undertriage to trauma centers (TCs) for older adults, the American College of Surgeons' Committee on Trauma and the Center for Disease Control revised field triage guidelines in 2011 with additional emphasis on direct transport to a Level I or II trauma center. Researchers examined whether age-based disparities in TC care for severe head injury decreased. Although patterns of increased TC treatment for all groups with severe head trauma indicate improvements, age-based disparities persisted.

Trends in follow-up of patients presenting to the emergency department with symptomatic cholelithiasis.
To better understand underuse of cholecystectomy, the researchers examined physician follow-up patterns after emergency department (ED) visits for symptomatic gallstones. They found that fewer than half of patients were evaluated by a surgeon after an initial ED visit for symptomatic gallstones. Patients who did not have physician follow-up were most likely to require emergent cholecystectomy, suggesting inappropriate ED discharge and highlighting the need for timely follow-up.

Outcomes of basic versus advanced life support for out-of-hospital medical emergencies.
The researchers compared outcomes after advanced life support (ALS) and basic life support (BLS) in out-of-hospital medical emergencies. They found that advanced life support is associated with substantially higher mortality for several acute medical emergencies than BLS.

Incidental findings on CT for suspected renal colic in emergency department patients: prevalence and types in 5,383 consecutive examinations.
This study aimed to determine the prevalence, importance, and types of incidental findings (IF) in non-enhanced CT scans performed for suspected renal colic, based on ACR white papers and other accepted radiographic recommendations. It found that important IF occurred in 12.7% of non-enhanced CT scans performed for suspected renal colic in the emergency department and are more common in older individuals.
