The likelihood of rupture of unruptured intracranial aneurysms that were less than 10 mm in diameter was exceedingly low among patients in group 1 and was substantially higher among those in group 2. The risk of morbidity and mortality related to surgery greatly exceeded the 7.5-year risk of rupture among patients in group 1 with unruptured intracranial aneurysms smaller than 10 mm in diameter.

Objective Medical errors in the emergency department (ED) occur frequently. Yet, common adverse event detection methods, such as voluntary reporting, miss 90% of adverse events. Our objective was to demonstrate the use of patient-reported data in the ED to assess patient safety, including medical errors. Methods Analysis of patient-reported survey data collected over a 1-year period in a large, academic emergency department. All patients who provided a valid e-mail or cell phone number received a brief electronic survey within 24 hours of their ED encounter by e-mail or text message with Web link. Patients were asked about ED safety-related processes. Results From Aug 2012 to July 2013, we sent 52,693 surveys and received 7103 responses (e-mail response rate 25.8%), including 2836 free-text comments (44% of respondents). Approximately 242 (8.5%) of 2836 comments were classified as potential safety issues, including 12 adverse events, 40 near-misses, 23 errors with minimal risk of harm, and 167 general safety issues (eg, gaps in care transitions). Of the 40 near misses, 35 (75.0%) of 40 were preventable. Of the 52 adverse events or near misses, 5 (9.6%) were also identified via an existing patient occurrence reporting system. Conclusions A patient-reported approach to assess ED-patient safety yields important, complementary, and potentially actionable safety information.

Oncology patients requiring rapid response team activation have a significantly higher in-hospital mortality rate, particularly if the rapid response team requires ICU transfer. Oncology patients also utilize rapid response team resources at a much higher rate.
