Comparative Study
Association between helicopter vs ground emergency medical services and survival for adults with major trauma.
Helicopter emergency medical services and their possible effect on outcomes for traumatically injured patients remain a subject of debate. Because helicopter services are a limited and expensive resource, a methodologically rigorous investigation of its effectiveness compared with ground emergency medical services is warranted. ⋯ Among patients with major trauma admitted to level I or level II trauma centers, transport by helicopter compared with ground services was associated with improved survival to hospital discharge after controlling for multiple known confounders.

A previous randomized trial demonstrated that adding bevacizumab to carboplatin and paclitaxel improved survival in advanced non-small cell lung cancer (NSCLC). However, longer survival was not observed in the subgroup of patients aged 65 years or older. ⋯ Adding bevacizumab to carboplatin and paclitaxel chemotherapy was not associated with better survival among Medicare patients with advanced NSCLC.

Comparative Study
Comparison of long-term survival after open vs endovascular repair of intact abdominal aortic aneurysm among Medicare beneficiaries.
Endovascular repair of abdominal aortic aneurysm (AAA) compared with open repair increases perioperative survival, but it is not known if it increases long-term survival. ⋯ Among older patients with isolated intact AAA, use of open repair compared with endovascular repair was associated with increased risk of all-cause mortality and AAA-related mortality.
