The primary study objective was to evaluate insertion success rates. Secondary objectives included patient satisfaction, procedure time, complication rates, completion of therapy and dwell time of the novel AccuCath® 2.25″ Blood Control (BC) Catheter System (FDA approved) placed in difficult-access patients. This was a single-arm feasibility trial evaluating the AccuCath® 2.25″ BC Catheter System in a convenience sample of DIVA patients defined as at least two failed initial attempts or a history of difficult access plus the inability to directly visualize or palpate a target vein. ⋯ Preliminary results show that the AccuCath® 2.25″ BC Catheter System has excellent success rates in gaining vascular access in an extremely difficult patient population. The device did not lead to any significant complications. Patients were also very satisfied with the procedure.

Emergency physicians must be able to effectively prognosticate outcomes for patients presenting to the Emergency Department (ED) with chest pain. The HEART score offers a prognostication tool, but external validation studies are limited. We conducted an external retrospective validation study of the HEART score among ED patients presenting to our ED with chest pain from 1 January 2014 to 9 June 2014. ⋯ The area under the receiver operator curve (AUROC) is 0.885 (95% confidence interval 0.838-0.931). Patients with a HEART score ≤3 are at low risk for 6-week MACE. Hence, these patients may be candidates for outpatient follow-up instead of inpatient admission for cardiac risk stratification.
