To determine the sensitivity and specificity of the urine ketone dip test as a screening test for ketonemia in hyperglycemic patients and to compare the performance of the urine ketone dip test with the anion gap and serum bicarbonate level. ⋯ The urine ketone dip test has high sensitivity for detecting DKA and a high negative predictive value for excluding DKA in hyperglycemic patients with diabetes with any symptoms of illness. The urine ketone dip test is a better screening test for DKA and DK than the anion gap or serum bicarbonate.

As of March 1994, 45 states had laws that, to varying extents, required health practitioners to report cases of domestic violence (DV). Colorado passed a mandatory DV reporting law in 1995. Laws that mandate police involvement in cases of DV injuries have been criticized because of concerns that these laws deter victims from seeking medical care. We hypothesized that these laws would deter DV victims from seeking medical care. ⋯ Only rarely did mandatory reporting laws appear to adversely affect a patient's decisions to seek medical care in this study. The benefits of mandatory reporting must be measured to assure that they justify deterrence to a small minority of patients.

We conducted a 5-year time study analysis of emergency department patient care efficiency. Our specific aims were (1) to calculate the main ED patient care time intervals to identify areas of inefficiency, (2) to measure the effect of ED and inpatient bed availability on patient flow, (3) to quantitatively assess the effects of administrative interventions aimed at improving efficiency, and (4) to evaluate the relationship between waiting times to see a physician and the number of patients who leave without being seen (LWBS) by a physician. ⋯ Time studies are an effective method of identifying areas of patient care delay. In our ED, targeted administrative interventions apparently reduced the total ED LOS and improved overall efficiency. Despite initial decreases in ED LOS, efficiency appeared to be adversely affected by reductions in nursing and physician staffing and increases in our patient census. The strength of the relationship between waiting times to see a physician and the number of LWBS patients suggests that decreasing waiting times may reduce the number of LWBS patients.

The most common extraintestinal manifestation of Entamoeba histolytica, the agent of amebiasis, is a hepatic abscess. This infection is common throughout the world and can be associated with life-threatening consequences. Given the often nonspecific nature of the complaints related to an amebic abscess, a retrospective review of patients with confirmed disease was done to recognize the most common patterns of presentation. ⋯ Patients with amebic liver abscess do present to EDs in the southwestern United States, especially in areas with a high immigrant population from endemic areas. Patients with complaints of fever and right upper quadrant abdominal pain, especially men of Hispanic origin, warrant a high degree of vigilance. Whereas most laboratory studies are unhelpful, the diagnosis can often be made in the ED by means of a bedside ultrasonographic test. Treatment should be initiated with metronidazole with disposition to an inpatient medical service.
