Observational Study
Opioid Use During the Six Months After an Emergency Department Visit for Acute Pain: A Prospective Cohort Study.
Despite the frequent use of opioids to treat acute pain, the long-term risks and analgesic benefits of an opioid prescription for an individual emergency department (ED) patient with acute pain are still poorly understood and inadequately quantified. Our objective was to determine the frequency of recurrent or persistent opioid use during the 6 months after the ED visit METHODS: This was a prospective, observational cohort study of opioid-naive patients presenting to 2 EDs for acute pain who were prescribed an opioid at discharge. Patients were followed by telephone 6 months after the ED visit. Additionally, we reviewed the statewide prescription monitoring program database. Outcomes included frequency of recurrent and persistent opioid use and frequency of persistent moderate or severe pain 6 months after the ED visit. Persistent opioid use was defined as filling greater than or equal to 6 prescriptions during the 6-month study period. ⋯ Although 1 in 5 opioid-naive ED patients who received an opioid prescription for acute pain on ED discharge filled at least 2 opioid prescriptions in 6 months, only 1% had persistent opioid use. These patients with persistent opioid use were likely to report moderate or severe pain 6 months after the ED visit.

We compare effectiveness of different airway interventions during cardiopulmonary resuscitation for patients with out-of-hospital cardiac arrest. ⋯ Although there were no differences in long-term survival or neurologic outcome among these airway interventions, these system-based comparisons demonstrated that supraglottic airway was better than intubation or bag-valve-mask ventilation and intubation was better than bag-valve-mask ventilation in improving return of spontaneous circulation. The intubation success rate greatly influenced the meta-analytic results, and therefore these comparison results should be interpreted with these system differences in mind.

Risk of Venous Thromboembolism After Carbon Monoxide Poisoning: A Nationwide Population-Based Study.
Few studies have investigated the association between carbon monoxide (CO) poisoning and risk of venous thromboembolism. We aim to identify the risk of pulmonary embolism and deep venous thrombosis after CO poisoning. ⋯ We found that the risk of venous thromboembolism persisted for up to 90 days after CO poisoning. The risk was increased 22-fold for pulmonary embolism and 10-fold for deep venous thrombosis, especially in the first month after CO poisoning. Patients should be monitored for venous thromboembolism risk after CO poisoning.
