Importance of periodic reeducation of hospital-based nurses in capillary blood glucose monitoring and an evaluation of the usefulness of reflectance meters.
Precision and accuracy of capillary blood glucose measurements performed by general staff nurses were assessed before and after a modest reeducation program both with and without the use of reflectance meters. A total of 380 capillary glucose determinations were performed by nurses and the hospital laboratory on the same samples. Prior to reeducation, nurses using meters were more accurate than those reading visually, but no difference was found in precision. Reeducation improved precision equally in both groups while improving accuracy only in the group using meters. While glucose readings with the use of reflectance meters were statistically more accurate than those read visually, the percentage of readings within 10% and 20% of the laboratory readings was the same. Thus, the increased accuracy observed with meters may have little practical significance, suggesting that their use might better be based on other considerations, such as user confidence, convenience, cost, and quality control. Periodic education is, however, an essential component of any quality assurance program.

Variation in intravaginal pressure measurements.
The wide variation in intravaginal pressure measurements of the circumvaginal muscles (CVM) was studied in five subjects under well-controlled conditions. Previous research and clinical observations have indicated that fluctuations in the measurement of intravaginal pressure may be associated with time of day, day of testing, and existing stress factors. Subjects were assessed four times per day, on four consecutive days, for a total of 16 assessments. At each of the 16 conditions for a given subject, 10 CVM contractions lasting 12 seconds each were recorded and the variables, maximum pressure (MP10), peak maximum pressure (PMP), and abdominal pressure were analyzed. The within-subject variance was 15.5 (SD = 3.9); the between-subject variance was 132.4 (SD = 11.5). The effects of day, time, and stressor were analyzed by ANOVA specifically designed for variance estimates; no significant differences were found. The clinical observations that led to the study were not supported when systematically investigated. However, consistent data collection procedures appeared to reduce within-subject variance.
