Population‐based indicators of the coverage of key elements of high‐quality family planning services are tracked via household surveys with female respondents, yet little work has been done to establish their validity. We take advantage of existing data sets from Cambodia and Kenya to compare women's responses at exit interviews following a health facility visit against the observations of a trained third‐party observer during the visit. The results, which treat the observations as the reference standard, show that indicators that measure contraceptive methods received are accurately reported while indicators of whether the woman received her preferred method and whether information was “discussed” or “explained” during counseling are less reliably reported. Studies designed explicitly to assess the validity of family planning questions in household surveys, especially questions in large survey programs critical for monitoring demographic trends and programmatic coverage, are needed. 相似文献

This research analyzes the effect which recent speed limit increases on rural interstate highways have had upon accidents that are alcohol-related. Although there has been considerable work on the separate highway safety effects of higher speed limits and alcohol-related accidents, surprisingly little work has explicitly examined the relationship between them. Based upon extensive county wide data on alcohol-related accidents and several theoretically important determinants of these accidents for the state of Indiana and over the period 1981 through 1989, fixed effects models were estimated. For the state as a whole, the analysis finds that the increase in rural interstate speed limits increased alcohol-related accidents and the magnitude of the effect was statistically significant. In addition, the relaxed speed limit led to a significant redistribution of alcohol-related accidents away from higher speed environments and towards lower speed environments. With few exceptions, this was true for every type of alcohol-related highway accident examined. 相似文献

When a time-limited day treatment program was reconfigured to serve individuals with long-standing psychotic disorders, the number of treatment episodes exceeding six months rose to 70%. To justify this concentration of resources, the program needed methods to identify individuals for whom sustained treatment was appropriate. This report describes development of utilization review methods adapted to publicly funded day treatment of individuals with serious mental illness and training of clinicians in new documentation skills. Data from three years of operation suggest that symptom severity is not a reliable indicator of medical necessity in day treatment. As expected with a clinically based system, a composite measure of benefit and medical necessity indicators weighted toward functioning in living, learning, working, and socializing environments predicted physician reviewer denial of continued day treatment, but length of stay did not. 相似文献

Localized brain activation in response to moving visual stimuli was studied by functional magnetic resonance imaging (fMRI). Stimuli were 100 small white dots randomly arranged on a visual display. During the Motion condition, the dots moved along random, noncoherent linear trajectories at different velocities. During the Blink condition, the dots remained stationary but blinked on and off every 500 ms. The Motion and Blink conditions continuously alternated with 10 cycles per run and 6–8 runs per experiment. In half of the runs, the starting stimulus condition was Motion, while in the remaining runs it was Blink. A series of 128 gradient echo echoplanar images were acquired from 5–7 slices during each run using a 1.5 T GE Signa with an Advanced NMR echoplanar subsystem. The time series for each voxel were analyzed in the frequency domain. Voxels which demonstrated a significant spectral peak at the alternation frequency and whose phase changed in response to stimulus order were considered activated. These activated voxels were displayed upon high resolution anatomical images to determine the sites of activation and were also transformed into the coordinates of Talairach and Tournoux ([1988] Co-planar Stereotaxic Atlas of the Human Brain, New York: Thieme) for comparison to prior neuroimaging studies. Seven of ten subjects showed clusters of activation bilaterally at the junction of the temporal and occipital lobes (area 37) in response to moving stimuli. Most activated voxels were located within or adjacent to a region designated the parietal-temporal-occipital fossa, or PTOF. Five subjects also showed activation to moving stimuli in midline occipital cortex. The activated voxels in midline cortex had a significantly shorter phase delay in their MR signal change relative to voxels in PTOF. © 1995 Wiley-Liss, Inc. 1 1 This article is a US Government work and, as such, is in the public domain in the United States of America 相似文献

Recent major surgery is an exclusion criterion for thrombolysis. Six patients with acute ischemic stroke underwent intra-arterial thrombolysis after recent open heart surgery without clinically significant bleeding complications, although one patient developed a small, asymptomatic cerebellar hemorrhage. Intra-arterial thrombolysis may be an option for patients with cerebral embolism in the perioperative period. 相似文献
