Clinical Trial Controlled Clinical Trial
Are emergency departments really a "safety net" for the medically indigent?
This study was designed to quantify the willingness of emergency departments (EDs) and private care practitioners to see medically indigent patients. Three case scenarios were developed to represent severe, moderate, and mild problems that typically confront ED physicians. A female investigator made telephone calls using these scenarios, each time declaring herself to be medically indigent. ⋯ Private practitioners in the largest communities were significantly more reluctant to see the medically indigent than their peers in smaller communities (P < .05). For an insured caller, 55% of private practitioners would see the caller for < $30 and only 35% were not taking new patients or provided referral. In contrast to most private primary care practitioners, EDs are at least willing to serve as a triage point for the medically indigent and are often the primary-care "safety net" for the medically indigent.

Randomized Controlled Trial Clinical Trial
Does warming local anesthetic reduce the pain of subcutaneous injection?
The most frequent complaint noted with the use of lidocaine (or other amide local anesthetic) is stinging or burning pain associated with subcutaneous infiltration. The purpose of this study was to evaluate the efficacy of warming buffered lidocaine for reducing the pain of infiltration. Forty adult volunteers were entered into a randomized, crossover study conducted at a community teaching hospital. ⋯ The order or the initial side of the injection did not influence the pain scores. The study had a power of 80% to detect a 10-mm difference between the two solutions at alpha = .05. These results suggest that warming buffered lidocaine to body temperature (37 degrees C) does not reduce the pain of subcutaneous infiltration.

A prospective citywide cohort study was conducted from August 1, 1993, through May 31, 1994 to analyze the epidemiological characteristics of emergency medical services (EMS) in an Asian city. Of 5,459 studied cases, the leading 3 causes were trauma (49.7%), alcohol intoxication (8.6%), and altered mental status (AMS) (6.9%). Half of the studied cases needed no prehospital care and 16.4% needed advanced life support (ALS) care. ⋯ The response time, time on scene, and transportation time were 4.6, 4.3, and 9.4 minutes, respectively. This Oriental EMS system experienced very short prehospital times, many traffic accidents, and extremely few DOA cases. Because few patients required ALS care, an emergency medical technician-based EMS system would probably be able to handle the majority of prehospital patients.
