Multicenter Study Observational Study
Association of Discretionary Hospital Volume Standards for High-risk Cancer Surgery With Patient Outcomes and Access, 2005-2016.
Various clinical societies and patient advocacy organizations continue to encourage minimum volume standards at hospitals that perform certain high-risk operations. Although many clinicians and quality and safety experts believe this can improve outcomes, the extent to which hospitals have responded to these discretionary standards remains unclear. ⋯ Although volume remains an important factor for patient safety, the Leapfrog Group's minimum volume standards did not differentiate hospitals based on mortality for 3 of the 4 high-risk cancer operations assessed, and few hospitals were able to meet these standards. These findings highlight important tradeoffs between setting effective volume thresholds and practical expectations for hospital adherence and patient access to centers that meet those standards.

Observational Study
Population-Level Symptom Assessment Following Pancreaticoduodenectomy for Adenocarcinoma.
Postoperative morbidity associated with pancreaticoduodenectomy (PD) for pancreatic adenocarcinoma (PA) remains as high as 70%. However, to our knowledge, few studies have examined quality of life in this patient population. ⋯ There is a high prevalence of symptoms following PD for PA, with improvement over the first 3 months following surgery. In what to our knowledge is the largest cohort reporting on symptom burden for this population, we have identified factors associated with symptom severity. These findings will aid in managing patients' perioperative expectations and designing strategies to improve targeted symptom management.

Thromboembolic stroke attributable to an ipsilateral carotid artery plaque is a leading cause of disability in the United States and a major source of morbidity. Randomized clinical trials have demonstrated the efficacy of carotid endarterectomy and carotid stenting at minimizing stroke risk in patients with minor stroke and transient ischemic attack. However, there is no consensus on guidelines for medical management and the timing of revascularization in patients with multiple recurrent episodes of transient ischemic attack over hours or days, an acute neurological event known as crescendo transient ischemic attack. ⋯ Crescendo transient ischemic attack is best managed with optimal medical management as well as urgent carotid endarterectomy within 2 days of presentation. Surgical endarterectomy appears to be preferred because of the increased embolic potential of bifurcation plaque, whereas stenting is an option for patients with contraindications for surgery. With ongoing advances in cerebrovascular imaging and medical treatment of stroke, there is a need for better evidence to determine the optimal timing and preoperative medical management of patients with crescendo transient ischemic attack.
