The objective of this study was to systematically review studies on out-of-hospital cardiac arrest published according to the Utstein guidelines to describe the variability in factors of resuscitation and outcome. Articles that reported primary data on survival after out-of-hospital cardiac arrest in the Utstein style were included. Forty-seven articles were identified using Medline. ⋯ Even when data are reported in a uniform way as suggested by the Utstein template, there is a tremendous variability in outcome. This did not appear to be entirely explained by variability in the traditional risk factors for a low chance of survival. One cannot exclude the possibility of other factors being of ultimate importance for the outcome.

A prospective observational study was conducted in 2,007 patients experiencing chest pain to determine impact of local quality improvement (QI) measures on the use of glycoprotein (GP) IIb/IIIa inhibitors in the ED treatment of high-risk patients with non-ST-segment elevation acute coronary syndromes (ACS). Patients with injury on the initial ECG or new sustained injury on continuous ECG were excluded. QI interventions were as follows: control (0-4 mo): no interventions (standardized protocols and prewritten orders in place 4 months prior); phase I (5-8 mo): simple education/awareness program with posted drug information pamphlets and eligibility criteria; phase II (9-12 mo): mandated QI form with real-time feedback and focused one-on-one physician education championed by an ED physician QI advocate. ⋯ Percent of high-risk patients receiving therapy increased from 6.0% during the control phase to 16.1% during phase I and 50.9% during phase II. After controlling for patient demographics, patients treated during phase I had a 2.8 times increased odds (95% confidence interval CI: 0.8-10.3; P =.11 [not significant]) of receiving GP IIb/IIIa inhibitor relative to the control phase, and patients treated during phase II had a 20.2 times increased odds (95% CI: 6.1-66.9; P <.0001) of treatment. In conclusion, local QI measures incorporating standardized protocols, preprinted orders, physician education, and interactive feedback championed by an ED QI physician advocate can increase early use of GP IIb/IIIa inhibitors in the ED treatment of high-risk patients presenting with chest pain.

The purpose of this study was to evaluate ED documentation of patient pain in light of the Joint Commission of Accreditation of Healthcare Organization's emphasis on pain assessment and management. A prospectively designed pain management survey was offered to patients on ED discharge. Documentation of pain intensity by ED nurses and physicians was retrospectively reviewed. ⋯ Patients with severe pain on arrival (46% vs 31%, odds ratio [OR] = 1.9, P <.02), chest pain (72% vs 32%, OR = 5.4, P <.001), or those receiving powerful analgesics (62% vs 32%, 3.5, P <.001) were more likely to receive a documented subsequent pain assessment than other patients. Pain severity is not consistently documented in ED patients, especially after therapy has been provided. Patients with severe pain and those receiving powerful analgesics were more likely to have a pain assessment subsequent to ED therapy.

Thyrotoxic periodic paralysis (TPP) and sporadic periodic paralysis (SPP) are the most common causes of hypokalemic periodic paralysis (HPP) in EDs in Asia. Their neuromuscular presentations are almost indistinguishable. We conducted this study to identify clinical clues that can help EPs distinguish between TPP and SPP. ⋯ Systolic (SBP) but not diastolic blood pressure (SBP 145 +/- 4 vs 128 +/- 4 mm Hg, P < 0.001) and heart rate (106 +/- 3 vs 73 +/- 3 beats/min, P < 0.001) were significantly higher in those experiencing TPP than SPP. Among the biochemical factors, only plasma phosphate concentration (2.2 +/- 0.2 vs 3.2 +/- 0.2 mg/dL, P < 0.001) was significantly lower in those experiencing TPP than SPP. Systolic hypertension, tachycardia, and hypophosphatemia are clinical clues favoring the diagnosis of TPP.

The role of immediate stress testing in low-risk patients with a potential acute coronary syndrome has not been rigorously evaluated with respect to impact on 30-day cardiovascular events. We evaluated the impact of inpatient, outpatient, or no stress testing (ETT) on 30-day cardiovascular outcomes. We performed a prospective cohort study in which consecutive patients with chest pain were admitted to a non-intensive-care telemetry bed over 16 months. ⋯ The cardiovascular outcomes (with 95% confidence interval) for patients with inpatient ETT versus outpatient ETT versus no ETT were as follows: death, 0% (0-1.5%) vs 0% (0-4.1%) vs 1% (0.3-1.7%); AMI, 1% (0.1-2.4%) vs 1.4% (0.1-4.1%) vs 0.3% (0.1-0.7%); PCI, 0.5% (0.1-1.5%) vs 1.3% (0.1-4.1%) vs 0% (0-0.4%); and CABG, 0.5% (0.1-1.5%) vs 0% (0-4.1%) vs 0.2% (0.1-0.4%). There was no statistical difference in 30-day cardiovascular outcomes among patients who received inpatient, outpatient, or no ETT within 30 days. This suggests that patients with chest pain who are admitted to non-intensive-care telemetry (or observation unit) beds might not need stress testing before hospital release.
