[Q]: Abstract: Emergency department utilization by recipients of Aid to Families with Dependent Children (AFDC) in a metropolitan children's hospital was monitored during a 36-month period (July 1982 to June 1985). There were 92,495 emergency department visits recorded in this interval. During 12 months of this period (July 1983 to June 1984) a pilot program (Citicare) for AFDC recipients requiring prior authorization by the primary care physician for emergency department utilization was in effect. Emergency department census dropped dramatically and abruptly upon initiation of this program. Annual census for the targeted years reveals: 35,704 visits for the 12 months preceding this novel program, 25,543 visits for the 12 months of the program, and 31,248 visits for the 12 months following the pilot program. Total emergency department census was decreased by 23% and medical assistance utilization was decreased by 46% during the Citicare program. During the target period, self-pay clients decreased by 25%, and other categories (Champus, Hill-Burton, Crippled Children's Commission, etc.) increased by 6%. There was no corresponding decline in the number of patients admitted to the hospital through the emergency department during the monitoring period with 3,545, 3,555, and 3,922 annualized admissions respectively, for the targeted 12-month periods. These data suggest that the format of Medicaid programs can dramatically alter the utilization of emergency department services. Furthermore, the primary impact of this specific program was to decrease inappropriate emergency department use.

[Q]: Abstract: The authors have investigated the application of mode-locked and Q-switched Neodymium:YAG (Nd:YAG) lasers in ocular surgery by means of high-speed photography and hydrophone measurements. The incisive effect relies on the optical breakdown at the laser focus. Cavitation bubbles and acoustic transients are thereby generated. Their size and pressure amplitude have been measured at various laser-pulse energies. With a pulse energy of 5 mJ, the bubble is 1.5 to 2.3 mm in diameter and the pressure of the acoustic transient is 9 to 16 bar (130 to 230 psi) at a distance of 18 mm from the focal point. Bubble size and amplitude of the pressure pulse are always approximately 50% higher with a Q-switched laser than with a mode-locked laser. However, the size of the ruptures produced in a polyethylene membrane by the laser pulses is the same for both modes of operation. The energy balance shows that not only mechanical effects, but also thermal mechanisms are responsible for photodisruption.

[Q]: Abstract: To assess the best method of quantitating progression of coronary disease, we studied four measurements in 114 coronary segments from 35 medically treated patients from whom angiograms were obtained 5 years apart. Only stenoses of less than 70% that were visualized in nearly identical projections on both angiograms were evaluated. Vessel edges were measured by use of catheter calibration and an automated computer algorithm yielding two "absolute dimensions" (mean and minimum diameters) and two measurements (percent stenosis and atheroma area) that required a "normal reference" diameter. The coefficient of variation for repeated segment measurements was less for mean and minimum diameter than for percent stenosis and area of atheroma. The best measure of progression of coronary disease as determined by t test comparison of different methods was the change in mean diameter over time (6.7 +/- 14.1% decrease), whether calculated on a per coronary segment or per patient basis (p less than .001). Based on this measurement and its standard deviation of progression of coronary disease in this patient subset with relatively benign disease, it is estimated that 470 patients per group would be required for an interventional study to demonstrate a 33% reduction in disease progression (207 patients for 50% reduction) at a 95% confidence level and 90% power.
