In an effort to find prognostic indicators of improvement for a group of 34 hospitalized children, the relationship between improvement and initial test score was computed. A combination of rated improvement and improvement in Full Scale Wechsler IQ was used as the criterion of improvement. Initially high scores on the Goodenough Draw-A-Man, Wechsler Performance IQ, Similarities, and Picture Completion subtests were significantly related to subsequent improvement in the hospital setting. Initially low deviation scores on Digit Span and Comprehension relative to the other subtests were found related to subsequent improvement. It is concluded that children with a normal intellectual potential but incapacitated by anxiety or other acute emotional disturbances show the most improvement in a hospital setting.

OBJECTIVES: We correlated preoperative urodynamic and intraoperative endoscopic findings with initial improvement, single collagen injection effectiveness for intrinsic sphincter deficiency (ISD), and long-term improvement following transurethral collagen injection for stress urinary incontinence (SUI). METHODS: Since 1993, 79 patients have been treated with transurethral collagen injection by the same urologist. Of these patients, intraoperative photographs of urothelial coaptation immediately after injection were available in 67 patients: 35 women with ISD, 24 men with incontinence, primarily following prostatectomy, and 8 children with neurogenic bladder. Urothelial coaptation was described as snug, fair, or poor. Preoperative Valsalva leak point pressure (VLPP), detrusor instability, impaired bladder compliance, bladder neck appearance, urothelial scarring, and degree of coaptation were correlated with both initial and long-term improvement. Initial improvement was compared with long-term improvement. RESULTS: Initial improvement was experienced by 85% of all the subjects (86%) of the women, 80% of the men, and 100% of the children with a neurogenic bladder condition). Overall, 31% of patients had long-term improvement after a mean follow-up of 2.2 years, including 43% of the women, 13% of the men, and 33% of the children. The patients underwent a mean of 1.5 (1 to 4) collagen injections. There was a significant correlation between degree of coaptation and initial improvement (P = 0.003), but not with long-term improvement. There was no correlation between VLPP detrusor instability, impaired compliance, bladder neck appearance, or urethral scarring and initial improvement. There was no correlation between any parameter and long-term improvement or between initial and long-term improvement. CONCLUSIONS: Initial endoscopic appearance following collagen injection predicted initial, but not long-term, improvement after one collagen injection. Initial improvement was high in both men and women but decreased considerably over time, more so in men, and was not significantly correlated with long-term success. Urodynamic and endoscopic findings do not predict long-term success following collagen injection.  相似文献

Quality improvement efforts in the Iowa Department of Transportation Offices of Construction have persisted for three years and it appears that they will continue for the foreseeable future. This paper explains how the quality improvement process was started in those offices, describes how it operates, and examines why it continues. First the key functions and performance measuring system are described. Then the process improvement system is described, including both statewide activities and local field office activities. A discussion is included regarding steering team activities and reasons for the persistence of quality improvement activities. Finally, a model is provided that shows the foundations of quality improvement and the two plan-do-check-act cycles that are necessary for continued improvement.  相似文献
